Electric wire connection structure of connector terminal

摘要

A conductor (Wa) of the electric wire (W) whose insulated sheath (Wb) is removed from an extremity of the conductor to a location where the conductor projects backwards from a rear end of the terminal accommodating chamber (11) of the connector housing 10 is crimped and connected by means of a pair of crimping pieces (3b), and an area that ranges from the extremity of the conductor (Wa) to the location that includes an end of the insulated sheath (Wb) is covered with a resin (8).

1. An electric wire connection structure of a connector terminal in which an end of an electric wire is crimped and connected to a rear end of a connector terminal to be inserted, from behind, into a terminal accommodating chamber of a connector housing, the terminal accommodating chamber having a maximum cross-sectional dimension,
wherein the connector terminal comprises an electric connection section for connecting with a counterpart terminal in a front portion of the connector terminal, and an electric wire connection section to be crimped and connected to the end of the electric wire in a rear portion of the connector terminal, the electric wire connection section being formed from a bottom plate and a pair of crimping pieces that extend upwards from both side edges of the bottom plate so as to assume a substantially U-shaped profile when viewed in cross section; an insulated sheath of the end of the electric wire is removed from an extremity of the electric wire to a location where the electric wire projects backwards from a rear end of the terminal accommodating chamber of the connector housing, such that a conductor portion of the electric wire that is not covered by the insulated sheath extends outside of and projects outwardly beyond the rear end of the terminal accommodating chamber when the connector terminal is accommodated in the terminal accommodating chamber of the connector housing; a conductor of the electric wire exposed by removal of the insulated sheath is put on an upper surface of the bottom plate of the electric wire connection section, and the pair of crimping pieces of the electric wire connection section are curled inwardly so as to enwrap the conductor, whereby the conductor is crimped and connected so as to come into close contact with the upper surface of the bottom plate; and an area that ranges from an extremity of the conductor to a location including an edge of the insulated sheath by a portion of the conductor connected to the electric wire connection section is covered with a resin, wherein the area covered with the resin has a maximum cross-sectional dimension that is less than the maximum cross-sectional dimension of the terminal accommodating chamber.
