Impact tool head having cutting knife integrally molded with wire-insertion blade

摘要

A wire-insertion and cutting head for a telephone wire installing impact tool has a plurality of unitary wire-insertion and cutting blade elements embedded in a single resilient cutting blade support block. Each wire-insertion and cutting blade element has both a wire-insertion blade and an increased thickness knife edge molded as a single continuous hardened steel element. The knife edge is located relative to the slot in the cutting blade to ensure that the knife edge will consistently and reliably effect a clean cut of a respective wire against the surface of the terminal receptacle, as the wire is urged into the terminal receptacle by the blade during operation of the impact tool.
