Abstract

Miniature coaxial cables which include a terminal or drain wire under the ground sheath can be stripped for termination by hand, but this requires some care to avoid damaging the drain wire.

Coax Shield Stripping Tool

Miniature coaxial cables which include a terminal or drain wire under the ground sheath can be stripped for termination by hand, but this requires some care to avoid damaging the drain wire.

The process can be mechanized by a tool having a gripper block or jaw assembly 10, which also serves as a die for the stripping operation. Coaxial cable 12 is held in 10 with one end of 12 projecting. Hollow punch member 14 has a passageway 16 which serves to conduct air from a pressure source, not shown. As punch 14 approaches the outer end of the unstripped cable, the air is turned on to lift initially the outer edge of ground braid 18 of the coaxial cable. This leaves the end of dielectric core 20 and drain wire 22 exposed.

Then, with or without continued application of air, punch 14 is advanced in direction 24, over 20 and 22, and under 18, to the position shown. Punch 14 has a knife edge 26 which is bevelled internally to glide over 20 and 22 and is dimensioned to intercept the bore of anvil member 10, pinching off 18 without damage to other parts of the cable.

In a separate operation, not shown, punch 14 is reciprocated away from the cable, drain wire 22 is separated from 20, and a portion of 20 is stripped. This leaves a stub end of the central conductor 26 which, together with the end of 22, can be soldered to a plug or the like.
