DETAILED DESCRIPTION

(11) Referring generally to FIGS. 1-9, by way of examples, the present disclosure is directed to an electrical connection system 100. By way of examples, the present disclosure is also directed to a manufacturing system 200 (FIG. 1). Examples of the manufacturing system 200 include or utilize the electrical connection system 100 to provide quick and reliable power connections between electrically powered devices in an industrial application.

(12) Referring generally to FIG. 1 and to FIGS. 2-6, in one or more examples, the electrical connection system 100 includes a first electrical connector assembly 102 and a second electrical connector assembly 104. The first electrical connector assembly 102 and the second electrical connector assembly 104 provide a physical interface for transfer of electrical signals, such as for power, data, and/or audiovisual applications.

(13) Referring to FIGS. 2-6, in one or more examples, the first electrical connector assembly 102 includes a first housing 106 and a first terminal assembly 108. The first terminal assembly 108 is supported by the first housing 106. In one or more examples, the first terminal assembly 108 is fixed (e.g., non-movable) relative to the first housing 106.

(14) Referring now to FIGS. 2-5 and 7, in one or more examples, the second electrical connector assembly 104 includes a second housing 110 and a second terminal assembly 112. The second terminal assembly 112 is supported by the second housing 110. At least a portion of the second terminal assembly 112 is movable relative to the second housing 110 between an extended position (e.g., as shown in FIGS. 2 and 4) and a retracted position (e.g., as shown in FIGS. 3 and 5). The second connector assembly 104 also includes biasing member 114. The biasing member 114 biases the second terminal assembly 112 toward the extended position (FIGS. 2 and 4).

(37) In one or more examples, upon contact of the first terminal assembly 108 and the second terminal assembly 112, the first insulator face 140 and the second insulator face 142 are not in contact. In one or more examples, upon contact of the first terminal assembly 108 and the second terminal assembly 112, the first insulator face 140 and the second insulator face 142 are adjacent and proximate to (e.g., at or near without touching) each other.

(38) In one or more examples, the first power-terminal face 132 and the second power-terminal face 136 are circular in shape, viewed along a respective one of the first terminal axis 122 and the second terminal axis 130. In one or more examples, the first ground-terminal face 134 and the second ground-terminal face 138 are annular in shape, viewed along a respective one of the first terminal axis 122 and the second terminal axis 130. In one or more examples, the first insulator face 140 and the second insulator face 142 are annular in shape, viewed along a respective one of the first terminal axis 122 and the second terminal axis 130.

(39) In one or more examples, the first power-terminal face 132 and the second power-terminal face 136 are planar (e.g., flat). In one or more examples, the first ground-terminal face 134 and the second ground-terminal face 138 are planar. In one or more examples, the first insulator face 140 and the second insulator face 142 are planar. In other examples, one or more of the first power-terminal face 132, the second power-terminal face 136, the first ground-terminal face 134, the second ground-terminal face 138, the first insulator face 140, and the second insulator face 142 have a planar portion and a non-planar (e.g., contoured, curved, or otherwise non-flat shaped) portion.

(40) Referring to FIGS. 8 and 9, in one or more examples, the first insulator face 140 includes a first insulator-face planar portion 144 and a first insulator-face nonplanar portion 146. The second insulator face 142 includes a second insulator-face planar portion 148 and a second insulator-face nonplanar portion 150. In one or more examples, upon contact of the first terminal assembly 108 and the second terminal assembly 112, the first insulator-face planar portion 144 and the second insulator-face planar portion 148 are proximate and not in contact with one another. In one or more examples, upon contact of the first terminal assembly 108 and the second terminal assembly 112, the first insulator-face nonplanar portion 146 and the second insulator-face nonplanar portion 150 are proximate, not in contact with, and mate with one another. In one or more examples, at least a portion of the first insulator-face nonplanar portion 146 and at least a portion of the second insulator-face nonplanar portion 150 initially mate with one another upon proximate and partial contact arrangement of the first terminal assembly 108 and the second terminal assembly 112. Generally, the mating, non-contact arrangement of the first insulator-face nonplanar portion 146 and the second insulator-face nonplanar portion 150 provides an insulation shield that closes a radial gap between the abutting first and second power terminals 116, 124 and abutting first and second ground terminals 120, 128 to prevent electrical arcing between the first and second power terminals 116, 124 and the first and second ground terminals 120, 128 during initial contact of the first terminal assembly 108 and the second terminal assembly 112.

(41) In one or more examples, as illustrated in FIGS. 8 and 9, the first insulator-face nonplanar portion 146 includes or takes the form of a recess or groove, such as an annular recess or groove, that depends inwardly from the first insulator-face planar portion 144. The second insulator-face nonplanar portion 150 includes or takes the form of a protrusion or ridge, such as an annular protrusion or ridge, that projects outward from the second insulator-face planar portion 148. However, in other examples, this arrangement can be reversed.

The second power-terminal face 136 includes a second power-terminal-face planar portion 156 and a second power-terminal-face nonplanar portion 158. In one or more examples, upon contact of the first terminal assembly 108 and the second terminal assembly 112, at least a portion of the first power-terminal-face nonplanar portion 154 and the second power-terminal-face nonplanar portion 158 mate with and contact one another. In one or more examples, upon contact of the first terminal assembly 108 and the second terminal assembly 112, at least a portion of the first power-terminal-face planar portion 152 and the second power-terminal-face planar portion 156 contact one another. Generally, the mating, contact arrangement of the first power-terminal-face nonplanar portion 154 and the second power-terminal-face nonplanar portion 158 ensures at least some degree of surface contact between the first power-terminal face 132 and the second power-terminal face 136. Additionally, the first power-terminal-face nonplanar portion 154 and the second power-terminal-face nonplanar portion 158 increase the contact surface area between the first power-terminal face 132 and the second power-terminal face 136. Further, the first power-terminal-face nonplanar portion 154 and the second power-terminal-face nonplanar portion 158 center and/or urge the first terminal assembly 108 and the second terminal assembly 112 into at least approximately co-axial alignment (e.g., approximate alignment of the first terminal axis 122 and the second terminal axis 130) upon contact.

(43) In one or more examples, as illustrated in FIGS. 8 and 9, the first power-terminal-face nonplanar portion 154 includes or takes the form of a protrusion, such as a spherical or semi-spherical protrusion that projects outwardly from the first power-terminal-face planar portion 152. The second power-terminal-face nonplanar portion 158 includes or takes the form of a recess that depends inwardly from the second power-terminal-face planar portion 156. However, in other examples, this arrangement can be reversed.

(44) Referring generally to FIGS. 2 and 3 and particularly to FIGS. 7 and 9, in one or more examples, the second power terminal 124, the second insulator 126, and the second ground terminal 128 are movable along the second terminal axis 130 relative to the second housing 110 (the second housing 110 is not shown in FIG. 9). Movement of the second power terminal 124, the second insulator 126, and the second ground terminal 128 enables establishing the electrical connection while accommodating for imperfect positioning or alignment of the first terminal assembly 108 and the second terminal assembly 112.

(45) In one or more examples, the second power terminal 124 is coupled and fixed relative to the second insulator 126. The second insulator 126 is coupled and fixed relative to the second ground terminal 128. The second ground terminal 128 is coupled and movable relative to the second housing 110. As such, in these examples, the second power terminal 124, the second insulator 126, and the second ground terminal 128 move as a unit relative to the second housing 110.

(46) In one or more examples, the biasing member 114 includes a first spring 160. The first spring 160 is engaged with the second housing 110 (not shown in FIG. 9) and the second ground terminal 128. In one or more examples, the first spring 160 is a coil spring disposed or situated around the second ground terminal 128 and between the second ground terminal 128 and the second housing 110. In these examples, the second ground terminal 128 and the second housing 110 each includes a motion limiter or stop that provides a stop to the extended position and the retracted position or that otherwise limits linear movement (e.g., extension and retraction) of the second terminal assembly 112.

(47) In one or more of these examples, the second electrical connector assembly 104 also includes a first gasket 162. The first gasket 162 is situated between the second housing 110 and the second ground terminal 128. The first gasket 162 provides an internal seal interface between mating surfaces of the second housing 110 and the second ground terminal 128 and prevents debris or other environmental contaminates from entering the second hollow interior 180 of the second housing 110. In one or more examples, the first gasket 162 is a rubber O-ring.

(48) In one or more examples, the first gasket 162 also provides some conformity to the second terminal assembly 112 for accommodating imperfect alignment of the first terminal assembly 108 and the second terminal assembly 112. For example, the first gasket 162 can enable the second terminal assembly 112 (e.g., the combination of the second power terminal 124, the second insulator 126, and the second ground terminal 128) to float relative to the second housing 110 or otherwise partially rotate or pivot about an axis that is perpendicular to the second terminal axis 130.

(49) In one or more examples, the second power terminal 124 and the second insulator 126 are movable relative the second ground terminal 128. Movement of the second power terminal 124 and the second insulator 126 relative to the second ground terminal 128 enables establishing the electrical connection while accommodating for imperfect positioning or alignment of the first terminal assembly 108 and the second terminal assembly 112. Movement of the second power terminal 124 and the second insulator 126 relative to the second ground terminal 128 also enables the second power terminal 124 and the second insulator 126 to be at a different position along the second terminal axis 130 relative to the second ground terminal 128 during contact between the first terminal assembly 108 and the second terminal assembly 112 and/or during extension and/or retraction of the second terminal assembly 112.

(50) In one or more examples, the second power terminal 124 is coupled and fixed relative to the second insulator 126. The second insulator 126 is coupled and movable relative to the second ground terminal 128. The second ground terminal 128 is coupled and fixed relative to the second housing 110. As such, in these examples, the second power terminal 124 and the second insulator 126 move as a unit relative to the second ground terminal 128 and the second housing 110.

(51) In one or more examples, the biasing member 114 includes a second spring 164. The second spring 164 is engaged with the second ground terminal 128 and the second insulator 126. In one or more examples, the second spring 164 is a coil spring disposed or situated around the second insulator 126 and between the second insulator 126 and the second ground terminal 128. In these examples, the second insulator 126 and the second ground terminal 128 each includes a motion limiter or stop that provides a stop to the extended position and the retracted position or that otherwise limits linear movement (e.g., extension and retraction) of the second terminal assembly 112.

(52) In one or more of these examples, the second electrical connector assembly 104 also includes a second gasket 166. The second gasket 166 is situated between the second ground terminal 128 and the second insulator 126. The second gasket 166 provides an internal seal interface between mating surfaces of the second insulator 126 and the second ground terminal 128 and prevents debris or other environmental contaminates from entering the second terminal assembly 112. In one or more examples, the second gasket 166 is a rubber O-ring.

(53) In one or more examples, the second gasket 166 also provides some conformity to the second terminal assembly 112 for accommodating imperfect alignment of the first terminal assembly 108 and the second terminal assembly 112. For example, the second gasket 166 can enable the combination of the second power terminal 124 and the second insulator 126 to float relative to the second ground terminal 128 or otherwise partially rotate or pivot about an axis that is perpendicular to the second terminal axis 130.

(54) In one or more examples, the second power terminal 124, the second insulator 126, and the second ground terminal 128 are movable relative to the second housing 110. The second power terminal 124 and the second insulator 126 are also separately movable relative the second ground terminal 128. In these examples, the biasing member 114 includes the first spring 160 engaged with the second housing 110 and the second ground terminal 128 and the second spring 164 engaged with the second ground terminal 128 and the second insulator 126. In one or more of these examples, the second electrical connector assembly 104 also includes the first gasket 162 situated between the second housing 110 and the second ground terminal 128 and the second gasket 166 situated between the second ground terminal 128 and the second insulator 126.

(55) In one or more examples, the second power terminal 124 is coupled and fixed relative to the second insulator 126. The second insulator 126 is coupled and movable relative to the second ground terminal 128. The second ground terminal 128 is coupled and movable relative to the second housing 110. As such, in these examples, the second power terminal 124, the second insulator 126, and the second ground terminal 128 can move as a unit relative to the second housing 110, the second power terminal 124 and the second insulator 126 can also move as a unit relative to the second ground terminal 128, and the second ground terminal 128 can move relative to the second housing 110 and the second power terminal 124 and the second insulator 126.

(56) Referring now to FIGS. 2-6, in one or more examples, the first electrical connector assembly 102 includes a seal 168. The seal 168 is situated around the first ground terminal 120 of the first terminal assembly 108. In one or more examples, the seal 168 is situated along a periphery of the first ground-terminal face 134. In one or more examples, the seal 168 circumscribes the first terminal axis 122 (FIG. 8) radially outward of the first ground-terminal face 134. In one or more examples, upon contact of the first terminal assembly 108 and the second terminal assembly 112 (FIG. 3), the seal 168 is configured to engage the second housing 110. The seal 168 provides an external seal interface around the abutting contact surfaces of the first terminal assembly 108 and the second terminal assembly 112 and prevents debris or other environmental contaminates from entering therebetween.

(57) Referring now to FIGS. 1-7, in one or more examples, the first electrical connector assembly 102 includes a third terminal assembly 170. The third terminal assembly 170 is supported by the first housing 106. The third terminal assembly 170 is electrically connected to the first terminal assembly 108. In one or more examples, the third terminal assembly 170 is electrically connected to the first terminal assembly 108 via a first electrical line 182 located in the first hollow interior 176 of the first housing 106.

(58) The third terminal assembly 170 includes any electrical connection terminal suitable for electrical connection to another device. For example, the third terminal assembly 170 is configured to be electrically connected to a machine tool 202 (FIG. 1). As an example, the third terminal assembly 170 includes a pair (e.g., male and female) electrical connector that are mated and mechanically coupled to establish an electrical connection between the machine tool 202 and the first terminal assembly 108.

The fourth terminal assembly 172 is electrically connected to the second terminal assembly 112. In one or more examples, the fourth terminal assembly 172 is electrically connected to the second terminal assembly 112 via a second electrical line 184 located in the second hollow interior 180 of the second housing 110.

(60) The fourth terminal assembly 172 includes any electrical connection terminal suitable for electrical connection to another device. For example, the fourth terminal assembly 172 is configured to be electrically connected to a power supply 206 (FIG. 1) or to an automated manipulator 204 (FIG. 1). As an example, the fourth terminal assembly 172 includes a pair (e.g., male and female) electrical connector that are mated and mechanically coupled to establish an electrical connection between the power supply 206 and the second terminal assembly 112.

(61) Referring to FIG. 1, in one or more examples, the electrical connection system 100 is utilized in an industrial application for supplying power to a machine, a tool, or other manufacturing device. In one or more examples, the manufacturing system 200 includes an automated manipulator 204 and the machine tool 202. The manufacturing system 200 includes the first electrical connector assembly 102 that is coupled to the machine tool 202 and that may also be referred to as a tool-side connector assembly. The manufacturing system 200 includes the second electrical connector assembly 104 that is coupled to the automated manipulator 204 and that may also be referred to as a machine-side connector assembly. The first terminal assembly 108 and the second terminal assembly 112 are configured to contact each other to establish an electrical connection upon coupling the machining tool 202 to the automated manipulator 204.

(62) In one or more examples, the automated manipulator 204 is an industrial robot or other robotic manipulator. The present disclosure recognizes that industrial robots perform a variety of tasks involving the movement and/or manipulation of physical objects. For example, a typical industrial robot includes a robotic arm equipped with a tool that allows the robot to automatically perform any one of various tasks, such as picking up, moving, drilling, cutting, welding, joining, applying fasteners, and the like. As a result, many different types of end effectors have been developed for deployment and use on robotic manipulators. The end effector includes the tool that is designed to perform one or more operations. The end effector also includes a linkage or coupling system that enables different end effectors to be interchangeably mounted to the end of the robotic manipulator. Such mechanical connection of different end effectors and, thus, different tools to the robot is often performed automatically. However, accommodating automatic electrical connections when interchanging different end effectors and, thus, different tools is more difficult. Accordingly, the electrical connection system 100 disclosed herein facilitates simple and reliable automatic electrical connection between the machine tool 202 and the power supply 206 during or upon mechanical connection of the machine tool 202 to the automated manipulator 204.

(63) In one or more examples, the machine tool 202 is any one of various tools used for processing or machining a workpiece and that requires electrical power. An example of the machine tool 202 includes a cutter, such as an ultrasonic or transducer cutter.

(64) In one or more examples, the manufacturing system 200 includes a mechanical coupling system 208. The coupling system 208 is configured to couple the machine tool 202 and the automated manipulator 204 together. In one or more examples, the mechanical coupling system 208 includes a first, or a tool-side, coupling assembly that is coupled to the machine tool 202. The mechanical coupling system 208 also includes a second, or a machine-side, coupling assembly that is coupled to the automated manipulator (e.g., robotic arm). The mechanical coupling system 208 is configured to automatically connect the first coupling assembly and the second coupling assembly when placed into alignment and contact, such as via an electromechanical or pneumatic actuator.

(65) In one or more examples, the first terminal assembly 108 and the second terminal assembly 112 are configured to contact each other to establish the electrical connection upon coupling the machining tool 202 to the automated manipulator 204 using the mechanical coupling system 208. In one or more examples, the first terminal assembly 108 and the second terminal assembly 112 are at least approximately aligned with each other during alignment and connection of the mechanical coupling system 208. During and/or following connection of the mechanical coupling system 208, the first terminal assembly 108 and the second terminal assembly 112 are in abutting contact and the electrical connection is established. The biasing member 114 holds the first terminal assembly 108 and the second terminal assembly 112 in abutting contact and maintains the electrical connection.

(66) As illustrated in FIGS. 2 and 3, in one or more examples, in the extended position (FIG. 2), a portion of the second terminal assembly 112 extends from the second housing 110. The first terminal assembly 108 and the second terminal assembly 112 are aligned upon coupling the machine tool 202 and the automated manipulator 204 together. The first terminal assembly 108 is configured to move the second terminal assembly 112 toward the retracted position (FIG. 3) upon contact of the first terminal assembly 108 and the second terminal assembly 112. The biasing member 114 urges the first terminal assembly 108 and the second terminal assembly 112 in abutting contact.

(67) Referring now to FIG. 10 and to FIGS. 1-9, by way of examples, the present disclosure is further directed to an electrical connection method 1000. Examples of the method 1000 are implemented using the electrical connection system 100 (FIGS. 1-9).

(68) Referring to FIG. 10, in one or more examples, the method 1000 includes a step of (block 1002) coupling the machine tool 202 and the automated manipulator 204 together. In one or more examples, the machine tool 202 and the automated manipulator 204 are automatically coupled together using the mechanical coupling system 208.

(69) In one or more examples, the method 1000 includes a step of coupling the first electrical connector assembly 102 to the machine tool 202. In one or more examples, the first housing 106 is mechanically coupled (e.g., via fasteners) to the machine tool 202. The first terminal assembly 108 is electrically coupled to the machine tool 202, for example, via the third terminal assembly 170. The step of coupling the first electrical connector assembly 102 to the machine tool 202 is performed before the step of (block 1002) coupling the machine tool 202 and the automated manipulator 204 together.

(70) In one or more examples, the method 1000 includes a step of coupling the second electrical connector assembly 104 to the automated manipulator 204.

The step of coupling the second electrical connector assembly 104 to the automated manipulator 204 is performed before the step of (block 1002) coupling the machine tool 202 and the automated manipulator 204 together.

(71) In one or more examples, the method 1000 includes a step of (block 1004) contacting the first terminal assembly 108 of the first electrical connector assembly 102, which is coupled to the machine tool 202, and the second terminal assembly 112 of the second electrical connector assembly 104, which is coupled to the automated manipulator 204, upon (e.g., during or upon completion of) the step of (block 1002) coupling the machine tool 202 and the automated manipulator 204 together.

(72) In one or more examples, the method 1000 includes a step of (block 1006) establishing an electrical connection between the first terminal assembly 108 and the second terminal assembly 112 upon (e.g., during or upon completion of) the step of (block 1004) contacting the first terminal assembly 108 and the second terminal assembly 112.

(73) In one or more examples, the method 1000 includes a step of (block 1008) biasing the first terminal assembly 108 and the second terminal assembly 112 in abutting contact. Biasing the first terminal assembly 108 and the second terminal assembly 112 in abutting contact holds the electrical connection.

In various examples, the elements may be associated directly or indirectly. As an example, element A may be directly associated with element B. As another example, element A may be indirectly associated with element B, for example, via another element C. It will be understood that not all associations among the various disclosed elements are necessarily represented. Accordingly, couplings other than those depicted in the figures may also exist.

(80) As used herein, the term approximately refers to or represent a condition that is close to, but not exactly, the stated condition that still performs the desired function or achieves the desired result. As an example, the term approximately refers to a condition that is within an acceptable predetermined tolerance or accuracy, such as to a condition that is within 10% of the stated condition. However, the term approximately does not exclude a condition that is exactly the stated condition. As used herein, the term substantially refers to a condition that is essentially the stated condition that performs the desired function or achieves the desired result.

(82) In FIG. 10, referred to above, the blocks may represent operations, steps, and/or portions thereof and lines connecting the various blocks do not imply any particular order or dependency of the operations or portions thereof. It will be understood that not all dependencies among the various disclosed operations are necessarily represented. FIG. 10 and the accompanying disclosure describing the operations of the disclosed methods set forth herein should not be interpreted as necessarily determining a sequence in which the operations are to be performed. Rather, although one illustrative order is indicated, it is to be understood that the sequence of the operations may be modified when appropriate. Accordingly, modifications, additions and/or omissions may be made to the operations illustrated and certain operations may be performed in a different order or simultaneously. Additionally, those skilled in the art will appreciate that not all operations described need be performed.

(83) Further, references throughout the present specification to features, advantages, or similar language used herein do not imply that all of the features and advantages that may be realized with the examples disclosed herein should be, or are in, any single example. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an example is included in at least one example. Thus, discussion of features, advantages, and similar language used throughout the present disclosure may, but do not necessarily, refer to the same example.

(84) The described features, advantages, and characteristics of one example may be combined in any suitable manner in one or more other examples. One skilled in the relevant art will recognize that the examples described herein may be practiced without one or more of the specific features or advantages of a particular example. In other instances, additional features and advantages may be recognized in certain examples that may not be present in all examples. Furthermore, although various examples of the electrical connection system 100, the manufacturing system 200, and the method 1000 have been shown and described, modifications may occur to those skilled in the art upon reading the specification. The present application includes such modifications and is limited only by the scope of the claims.
