Wire Stripper

This hand-operated wire stripper parts insulation near the end of a wire so that the parted portion can then be manually removed.

The device comprises handle 9 having lower fixed jaw 10 and upper movable jaw 11. The jaws each carry one half of split holding die 12 and of stripping die
13. The latter die is carried by slide 19 that is movable along jaw 10 in response to movement of a trigger 14 connected to it by link 20. The upper end of trigger 14 is a cam comprising two notches 15 and 16 located at opposite ends of land
17. The cam actuates a cam follower 18 to open and close the jaws upon movement of trigger 14.

In operation, the end of an insulated wire is inserted into the open jaws and dies. Trigger 14 is squeezed causing the jaws to close and causing dies 12 and 13 to bite into the insulation. Continued squeezing of trigger 14 moves die 13 away from die 12 to part the insulation until the jaws open, as follower 18 drops into notch 16. Then, the wire can be removed. During parting, die 12, because it bites into the insulation, positively holds the insulation in contrast to a frictional or pressure holding action. It provides a clean circular cut free from tails or damaged ends.
