DETAILED DESCRIPTION
(22) Disclosed examples will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all of the disclosed examples are shown. Indeed, several different examples may be described and should not be construed as limited to the examples set forth herein. Rather, these examples are described so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those skilled in the art.
(23) Within examples herein, a bracket is described to provide self-aligning features between two mated connectors, and is advantageously suited to circular connectors that are intended to be autonomously de-mated or decoupled. The bracket can also be used for rectangular connectors, or other configured and oriented connectors, where rotational and translational degrees of freedom are needed for decoupling. The bracket helps to lessen or eliminate any potential for the two mated connectors to bind, which may be caused by manufacturing, assembly, vibration, or thermal variations of an apparatus. In one example, an apparatus is described for reducing risk of binding between two connectors during decoupling of the two connectors. A first connector is associated with a first component and a second connector is attached to a cable that is subjected to a pulling force to effect decoupling. The apparatus includes a bracket that is rigidly affixed to the first component and that supports the first connector so as to enable the first connector to automatically align with the pulling force. The bracket may include a spherical bearing, a shoulder bolt, a mounting bracket, and a pivot bracket coupled to the first connector. The shoulder bolt is oversized so that the pivot bracket can move forward and backward in addition to right/left and roll/pitch movements enabled by the spherical bearing. The bracket configuration enables a smooth disconnect of the two mated connectors regardless of any connectors orientation.
(24) Referring now to
(25) The first connector 102 is connected to the first component 104 through cable(s) 103. The first connector 102 may be an electrical connector, and thus may include pins or slots to receive pins. The first connector 102 may also be a fluid connector to transfer fluid from the first component 104 to the second connector 106. In such an example, the cable(s) 103 and 108 may be replaced by fluid pathways, such as tubing. In addition, although the cable(s) 103 and 108 are shown as multiple cables, a single cable or wire, or a single cable harness or wire harness may be used. The first connector 102 may be any shapes (circular, rectangle, etc.) and may be configured in a male or female format.
(26) The first component 104 may be any type of component such as an electrical component or electrical controller, or a fluidic component such as a fluid storage container, for example.
(27) The second connector 106 is configured to secure to the first connector 102, and can be the male/female connector that matches to the female/male connector configuration of the first connector 102. The second connector 106 is attached to the cable(s) 108 that connect to a second component 109. The second component 109 can be similar to the first component 104 or complimentary to the first component 104 depending on an application of use of the apparatus 100.
(28) The bracket 110 is rigidly affixed to the first component 104. As shown in
(29) The bracket 110 includes a mounting bracket 112, a spherical bearing 114 disposed within the mounting bracket 112, a pivot bracket 116 disposed adjacent the mounting bracket 112, and a shoulder bolt 118 extending through the spherical bearing 114, the mounting bracket 112, and the pivot bracket 116. The shoulder bolt 118 connects the pivot bracket 116 to the mounting bracket 112, and the shoulder bolt 118 is secured in place using washers and nut 119.
(30) The mounting bracket 112 includes a mount 120 in which the spherical bearing 114 is disposed, and the pivot bracket 116 is positioned over the mount 120 with the shoulder bolt 118 extending through the spherical bearing 114, the mount 120, and the pivot bracket 116.
(31) The mounting bracket 112 includes a base 122, and a first arm 124 and a second arm 126 coupled to sides of the base 122. In this example configuration, the mounting bracket 112 is a U shape. A first end 128 of the pivot bracket 116 is coupled to the mount 120 of the base 122 and a second end 130 of the pivot bracket 116 is coupled to the first connector 102. The first connector 102 is connected to the pivot bracket 116 using screws 105. As shown in
(32) The mounting bracket 112 also includes supports 121 and 123 that connect sides of the mount 120 with the first arm 124 and the second arm 126, respectively. The base 122, the first arm 124, the second arm 126, the supports 121 and 123, and the mount 120 of the mounting bracket 112 can all be formed as an integral component, or as a single part, so that all of these features are manufactured to be integral into the mounting bracket 112, for example. In some examples, the mounting bracket 112 comprises aluminum, steel, or other metal.
(33) The base 122 of the mounting bracket 112 includes a slot 132 to enable the cable(s) 103 to extend down to the first component 104. The cable(s) 103 can be routed around the shoulder bolt 118 through a center of the pivot bracket 116 and through the slot 132 to the first component 104.
(34) The pivot bracket 116 is attached to the mounting bracket 112 and a space 133 is provided between the second end 130 of the pivot bracket 116 and each of the first arm 124 and the second arm 126 enabling the pivot bracket 116 to rotate via the spherical bearing 114 with respect to the mounting bracket 112. This enables a roll, pitch, and yaw freedom of movement of the pivot bracket 116 with respect to the mounting bracket 112 because the pivot bracket 116 may move into the space 133 as enabled by the spherical bearing 114. The spherical bearing 114 may be many sizes, and scaled up or down, enabling more or less freedom of movement along the roll, pitch, and yaw axis. The spherical bearing 114 may also comprised of TEFLON and can rotate with application of low torque.
(35) In addition, within examples, the shoulder bolt 118 is oversized enabling the pivot bracket 116 to move along a longitudinal axis of the shoulder bolt 118. The shoulder bolt 118 is also lubricated with a lubricant, such as grease or a dry film lubricant, allowing movement of the pivot bracket 116 along the shoulder bolt 118 more easily, for example. Thus, because the pivot bracket 116 is connected to the mounting bracket 112 via the shoulder bolt 118 and the spherical bearing 114, this enables five degrees of freedom of movement of the pivot bracket 116 with respect to the mounting bracket 112.
(36) The cable(s) 103 that extends from the first connector 102 to the first component 104 can also have some extra length (e.g., slop) to allow movement of the pivot bracket 116 in various degrees of freedom.
(37) The first arm 124 and the second arm 126 of the mounting bracket 112 include flanges 134 and 136. The flanges 134 and 136 enable connection of a plate 138 using screws 140 and 142 to the mounting bracket 112. The plate 138 is secured over the first connector 102 and functions to partially enclose the mounting bracket 112 and/or the first connector.
(38)
(39)
(40) The pivot bracket 116 also includes an opening 158 on a top surface 160 of the pivot bracket 116 into which the first connector 102 is positioned. Then, the first connector 102 is connected to the pivot bracket 116 using screws 105 (shown in
(41) The first leg 150 and the second leg 154 of the pivot bracket 116 are triangular in shape to enable rotation of the pivot bracket 116 via the spherical bearing 114. The triangular shape provides clearance at the first end 128 of the pivot bracket 116 for the pivot bracket 116 to rotate and not contact the base 122 of the mounting bracket 112.
(42)
(43)
(44)
(45)
(46)
(47) Within examples, the pivot bracket 116 includes the opening 152 and the opening 156 through which the shoulder bolt 118 extends enabling longitudinal translation freedom of movement. The pivot bracket 116 is also coupled to the mounting bracket 112 with clearance and the open space 164 enables lateral translation freedom of movement. Furthermore, the pivot bracket 116 is coupled to the spherical bearing 114 with clearance enabling yaw, pitch, and roll freedom of movement.
(48)
(49) Thus, the apparatus 100 enables the first connector 102 to automatically align with a pulling force of the cables 108 of the second connector 106 so that a disconnection or decoupling of the first connector 102 and the second connector 106 can occur with little or no binding. The multiple degrees of freedom of movement provided by the bracket 110 including pitch, roll, yaw as well as shifting in an x-y plane enables a smooth disconnect of the first connector 102 from the second connector 106 regardless of any orientation of the first connector 102 and the second connector 106. In addition, within some examples, the multiple degrees of freedom of movement provided by the bracket 110 enable self-aligning of the first connector 102 to the pulling force of the cables 108. Thus, in an example where the second connector 106 and the first connector 102 are pulled apart, and the second connector 106 and the first connector 102 are not aligned with the pulling force, the pivot bracket 116 can enable self-aligning (through translational and/or rotational movement) toward the pulling force to prevent binding during decoupling. Preventing binding can be particularly useful in applications where two different connectors are separating from one another, and each of the connectors may be influenced by a different set of physical factors due to high speed, motion/rotation, mass etc.

(51) It should be understood that for this and other processes and methods disclosed herein, flowcharts show functionality and operation of one possible implementation of present examples. Alternative implementations are included within the scope of the examples of the present disclosure in which functions may be executed out of order from that shown or discussed, including substantially concurrent or in reverse order, depending on the functionality involved, as would be understood by those reasonably skilled in the art.
(52) The method 200 is useful in example scenarios with the first connector 102 associated with the first component 104 and the second connector 106 attached to the cable(s) 108 that is subjected to a pulling force to effect decoupling.
(53) At block 202, the method 200 includes securing the bracket 110 to the first component 104. The bracket 110 may be secured to the first component 104 through the cable(s) 103 or through other means such as screws, bolts, snap-fit, etc.
(54) At block 204, the method 200 includes aligning the first connector 102 with the pulling force via one or more of translational or rotational movement of the pivot bracket 116.
(55)
(56)
(57)
(58)
(59)
(60)
(61) The method 220 is useful in example scenarios with the first connector 102 associated with the first component 104 rigidly affixed to the bracket 110 that supports the first connector 102 and the second connector 106 is attached to the cable(s) 108.
(62) At block 222, the method 220 includes subjecting the cable(s) 108 to a pulling force. The pulling force may be performed in a number of manners, such as causing the second component 109 to move away from the first component 104. This can be performed manually, or autonomously.
(63) At block 224, the method 220 includes aligning the first connector 102 with the pulling force via one or more of translational or rotational movement of the pivot bracket 116 of the bracket 110.
(64) At block 226, the method 220 includes decoupling the first connector 102 and the second connector 106. The first connector 102 and the second connector 106 may snap into one another and decoupling can be performed by pulling the two connectors apart, or by application of the pulling force to the cable(s) 108, for example. Thus, the first connector 102 and the second connector 106 may not be rigidly affixed to one another so that they can be decoupled using the pulling force.
(65)
(66)
(67)
(68) At block 242, the method 240 includes inserting the spherical bearing 114 within the mounting bracket 112.
(69) At block 244, the method 240 includes positioning the pivot bracket 116 adjacent to the mounting bracket 112, and the first connector 102 is coupled to the pivot bracket 116.
(70) At block 246, the method 240 includes extending the shoulder bolt 118 through the spherical bearing 114, the mounting bracket 112, and the pivot bracket 116.
(71) At block 248, the method 240 includes securing the first component 104 to the first connector 102 coupled to the pivot bracket 116, and the pivot bracket 116 floats along two or more degrees of freedom of movement with respect to the mounting bracket 112 to prevent the first component 104 from binding during disconnect from the first connector 102.
