Wire Wrap Puller

Fig. 1 illustrates a hand tool for compressing the oval form of a wire wrapping, positioned about a generally rectangular shaped connector pin. The wire coil is illustrated in both its uncompressed and compressed form in Fig. 2.

By flattening the oval form of the wire wrap illustrated in Fig. 2, the tool illustrated in Fig. 1 relieves the tension in the wire which causes it to grip the rectangular pin. The wire wrap may then be pulled off the pin quickly and easily.

As illustrated in Fig. 1, jaws 5 are designed to slide easily over the oval wire wrap in place about a rectangular connection pin. Lever 1 is then pulled so that it rotates about pivot A. The first few degrees of rotation cause cam follower D to rotate cam 4 about pivot C, thus closing jaws 5 to compress the wire wrap. Continued movement of lever 1 brings cam follower D into a dwell position in cam 4, to hold the wire wrap in its compressed condition without increasing the pressure further. Continued rotation of lever 1 about pivot A brings it into contact with cam 3, which is then forced to rotate about pivot B. Cam 3 pulls jaws 5 back along guideways 9 by wires 8 attached to cam 3. The guideways 9 are on frame 2 and cam 4 and may be simple slides for jaws 5. The front portions of cam 4 and frame 2 can be positioned against the chassis on which the rectangular pin is mounted, to provide a resisting force to the reaction as the compressed oval wire is pulled off the pin.
