Wire Stripper

These wire strippers remove an outer jacket from a twisted pair wire while simultaneously unwinding the pair.

The wire to be stripped is shown at A and includes ground conductor 10. The latter is wrapped around insulated signal conductor 12. Ductile plastic outer jacket 14 is used to provide insulation and protection for the twisted wire pair. To strip jacket 14 from the twisted pair and simultaneously unwind wires 10 and 12, the strippers shown at B and C can be used. The wire stripper shown at B and B' utilizes a pair of highly-polished, rounded jaws 16 and 18 to provide the stripping action. Jaw 18 is spring-biased by springs 20 and 22 towards jaw 16. Set screws 24 and 26 provide an offset distance between the jaws.

In performing the stripping action, jaws 18 and 16 are forced apart by devices, not shown, and the wire to be stripped is inserted. Jaws 16 and 18 are then allowed to close upon the wire and the wire is withdrawn. The spring tension exerted upon jaw 18 is sufficient to cold-flow jacket 14. The latter is caused to rupture at the point where initial contact is made between the jaws and the material. The spring pressure exerted upon jaw 18 is sufficient to unwind conductors 10 and 12 as they are withdrawn.

As shown at C and C', a different stripper is provided which achieves a more precise cut. Cutting blades 30 and 32 form an oval when closed upon one another and provide a desired cutting action upon jacket 14. Oval guideways 34 and 36...
