Wire connector

摘要

Wire connector comprises a terminal of wound spring wire which is received in a cavity in a plastic base and contained therein by a plastic cover. The terminal comprises a first conical helix wound from a wire receiving end to a constricted end then back upon itself to form a shorter second helix ending at a shoulder. Conductors are twisted into the terminal causing it to expand and grip the conductors resiliently while a finger of spring metal prevents rotation relative to the housing. The first helix is nested in U-shaped recesses in partitions in the cavity so that the shoulder bears against a partition when the wires are pulled.
