SNAP ADAPTER FOR TOOL COMPONENT

Abstract

A snap adapter for a wire stripping tool has a hollow body with a tool end, a component end, and a button. The tool end is sized for insertion into the tool body and the component end is sized for receiving a component meant to strip a cable of a specified diameter. The button comprises a pin feature for attaching the received component. Inserting the component into the snap adapter forces the pin away from the snap adapter hollow body to allow for full insertion of the component into the tool body. A spring disposed between the hollow body and button pushes the pin feature upwards through the hollow body to hold the component inside the snap adapter once the component is fully inserted. Removing the component requires pushing down the button to extract the pin feature, which allows the component to be slideably removed from the tool body.

DESCRIPTION OF THE EMBODIMENT(S)

[0028] In describing the embodiment(s) of the present invention, reference will be made herein to FIGS. 1-10 of the drawings in which like numerals refer to like features of the invention.

[0029] A snap adapter 10 of the present invention is used to provide a more efficient way of quickly changing a sized working component 50 to the end 44 of a wire stripping tool body 40. The snap adapter 10 comprises an adapter body 12, with a component end 14 of the adapter body 12 being sized for receiving and holding a working component 50, and an end 16 of the adapter body 12 sized for securing into the end 44 of wire stripping tool 40. The snap adapter 10 is configured to be compatible with several different tool body types, including but not limited to the Ripley 22 Plus (FIGS. 8-9) and Ripley 44 Plus (FIG. 10) for securing one or more different components for stripping and/or cutting cables of different sizes or types.

[0030] As shown in FIGS. 8-9, the 22 Plus tool comprises a cylindrical tool body 40 with one female end 44 have a cylindrical opening sized for receiving the cylindrical tool end 16 of the snap adapter 10. The other end of the tool body 40 comprises a hexagonal-shaped node 60 projecting from its planar edge for insertion into a drill (not shown). This node 60 allows for drill-powered rotation of the tool about its longitudinal axis 70 when properly affixed to the drill, thus providing the proper motion needed for the attached component 50 to strip the outer jacket 82 from the cable 80.

[0031] FIG. 10 shows the Ripley 44 Plus tool embodiment of the tool body 40 using the snap adapter 10 of the present invention to secure a component 50 for hand powered stripping of the outer jacket from a cable. The tool body 40 of this embodiment comes in a cross, or X shaped profile, with each planar edge being sized for receiving the tool end 16 of the snap adapter 10. Adapter tool body end 16 is sized to be received within any of the four end 44 openings in the tool body 44. It is thus possible to attach four different sized components 50 to this particular tool body 40 at the same time. This tool in combination with the snap adapter 10 of the present invention especially is useful when the end-user is working with multiple sizes and types of cable (i.e. electrical, coaxial, Cat 5e, Cat 6, fiber optic, and the like). It eliminates the need for the end user to keep replacing the components attached to the tool body 40, therefore resulting in faster and more efficient results in cable-stripping tasks.

[0032] The snap adapter 10 attaches to the end 44 of the tool body 40/40 where cylindrical end 56 of a working component 50 would otherwise normally assemble. Component end 56 as shown has indentation or opening 57 which would normally receive a set screw 42 extending through an opening in the side of tool body end 44 to secure the component in place. As shown in FIGS. 8-10, the exemplary component 50 has a cylindrical body with a hollowed center, bore, or opening 52 for receiving a cable 80 end (FIG. 8). A portion of the planar surface of the component 50 cylindrical body is open into the hollowed center 52, and a blade 54 for stripping the outer jacket 82 off of a wire is affixed to the inside walls of the hollowed center 52 in a downward sloping angle. Insertion of a wire 80 end into the hollowed center 52 and rotation of the component 50 will create enough force for the blade 54 to cut, pierce and strip the cable jacket 82, exposing the wire or other core 84. A full 360 rotation of the component 50 will cut and remove the entirety of the cable jacket inserted into the component's 50 hollowed center 52, while the actual cable core 84 remains unscathed. Any other type of working component for cutting or stripping power- or data-carrying cable may be used in the present invention.

[0033] The snap adapter 10 of the present invention attaches at cylindrical end 16 to the opening in end 44 of the tool body 40/40 where a working component 50 would otherwise normally assemble, and end 16 is configured in a manner similar to component end 56. An indentation or opening 17 in end 16 receives set screw 42 in tool body end 44 to secure the adapter in place. At the opposite end 14 snap adapter 10 is configured to mate with the cylindrical end 56 of component 50, and the opening in end 14 is sized in a manner similar to the opening at end 44 of the tool body. Adapter 10 has a hollowed body with an inner diameter at end 14 where the end 56 of component 50 can be inserted in a tight-sliding fit, and then secured, as will be described further below. As shown in an exemplary embodiment in FIGS. 1-2, the snap adapter 10 is comprised of a generally cylindrical adapter body 12 with a component end 14 and a tool end 16, a slide member 20, a compression spring 22, and a retaining member 30. Adapter body 10 further includes a pin opening 19 on one surface of the opening in end 14 and on the exterior surface a spring relief opening 13 opposite the pin opening 19.

[0034] The slide member 20 is, in the embodiment shown, disposed between adapter ends 14 and 16 and moves with respect to adapter 10 in a direction normal to axis 70, and extends around and encompasses the body 12 of adapter 10. The retaining member 30 holds the slide member 20 in place on the adapter body 12 in a tight-sliding fit adjacent end 16, holding the slide member 20 between the component end 14 and the retaining member 30 (FIGS. 1 and 2). Its shape is generally round and ring-like with interior and exterior features configured for optimal functional and ergonomic operation. These features include pin 25, bearing flats 24, button 21, and a spring surface 23 as shown in FIG. 7.

[0035] The pin feature 25 extends within and protrudes through opening 19 in body 12 into the interior circumference of the slide member 20, on the opposite side of button portion 21. Force exerted on the button portion 21 allows for manual operation and movement of the pin 25. The pin 25 has a tapered entry point 25a in the form of a forward-facing ramp to allow components 50 to be inserted into the adapter 10 without the need to use the button 20. The ramp 25a will contact the leading edge of component end 56 and the pin 25 will be pushed and activated to move downward upon the continued insertion of the component 50. The angle of ramp 25a will not cause a jam or prevent a component 50 from being quickly assembled into the adapter 10. Upon full insertion of component end 56 into the opening in adapter end 14, pin 25 may slide upward into opening 57 in component end 56 to secure the component in place.

[0036] A compression spring flat surface 23 is disposed in a relief opening directly opposite the pin 25 on the interior of the slide member 20, and is aligned with spring relief opening 13 in adapter body 12. A compression spring 22 is disposed between surface 13 and opening 23 to urge button portion 20 away from adapter body 12 and pin 25 through opening 19 into the interior of the adapter body. Spring 22 is disposed directly beneath the button portion 21 to allow the user a tactical feel of the compression of the spring 22 and to align the force created by the spring 22 with the button portion 20 and pin 25. Once component end opening 57 is aligned with pin 25, the force of spring 22 causes the pin 25 to move into the opening.

[0037] Parallel bearing flats 24 along opposite sides of the inner surface of the slide member 20 slide along in contact with corresponding parallel bearing flats 18 on either side of the outer surface of adapter body 12. They are sufficiently long and broad to transmit torque from the adapter 10 to the pin feature 25, and provide the bearing surfaces for operation of the adapter 10.

[0038] The button portion 21 is the only part of the adapter 10 that the user needs to touch to remove the component 50. Its location approximately 180 opposed from the pin 25 enables the operator to exert force to move pin 25 along the line of movement of both button 20 and pin 25. Button portion 21 protrudes outside the diameter of the adapter 10 to allow for easy location and operation with a gloved hand, and may have a grooved/textured surface for a no-slip grip, which simultaneously makes it easier for an end user to locate.

[0039] The snap adapter 10 normally rests in the closed position as shown in FIGS. 3 and 4. When the component 50 is pressed into the tool body 40 by movement along axis 70, the leading edge of the end 56 of component 50 contacts a beveled pin 25 protruding from the slide member 20. The pushing force exerted onto the pin 25 which contacts the pin's sloped surface 25a naturally forces the slide member 20 into the open position (FIGS. 5-6). The end user can also physically push the button portion 21 of the slide member 20 to set the snap adapter 10 into the open position when they want to insert a component 50. To remove the component 50, the button portion 21 is depressed as shown in FIGS. 5 and 6 to remove pin 25 from component opening 57, and the component may be slid outward from adapter end 14.

[0040] When the slide member 20 is depressed in the open position, wherein button portion 21 is urged downward toward the adapter body 12 (FIG. 5), the exterior surface of slide member 12 may be sized so that it does not protrude beyond the adjacent surface of adapter body end 14 or retainer ring 30. When the button portion 21 is released and spring 22 urges it away from the adapter body, a recessed relief or clearance arc 26 is created opposite the button portion 21 on the exterior of the slide member 20, between adapter body end 14 or retainer ring 30 (FIGS. 3, 4 and 7). This allows for the user's fingers to squeeze directly normal to and across the axis 70 of the tool 40 and not limit the downward movement of the adapter 10. It also is sized to be flush with the diameter of the adapter 10 once the button is pressed so it doesn't protrude outside the envelope of the tool 40. This avoids confusion over which side is the operating button portion 21.

[0041] The adapter 10 provides an easily operable device through which all other components may connect to a common tool body. The adapter 10 allows for proper rotational alignment of the component and torque transmission between the component and the tool body.

[0042] The overall construction of the snap adapter 10 is modular as shown in FIGS. 8-10. The design allows for the end user to convert any standard tools that were originally designed to work with a component 50 into a quick disconnect tool in accordance with the present invention.

[0043] The snap adapter 10 and method of operation of the present invention provides a one-piece snap button 20 with integrated pin 25 for strength, durability, and reliability; a ramped, non-rotating pin 25 for easy component 50 installation with no need for button 20 actuation to install component 50; and an ergonomic push operation to remove the component 50. Additionally, it is modular to allow conversion of tools from standard to quick disconnect operation.

[0044] Accordingly, the present invention may include one or more of the following features and advantages:

[0045] The snap adapter assembly of the present invention includes one end designed for attachment to a wire stripping tool body, and the other end designed for the quick attachment and release of a component containing a blade for stripping or cutting a wire of a desired diameter.

[0046] The snap adapter assembly of present invention provides a method of component interchangeability that eliminates the need to use outside tools to secure the component.

[0047] The snap adapter assembly of the present invention enables the use of a gloved hand of the user to execute proper component transposition.

[0048] While the present invention has been particularly described, in conjunction with a specific preferred embodiment, it is evident that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.

[0049] Thus, having described the invention, what is claimed is:
