Connector containing front holder

Abstract

A connector is provided, which includes a connector housing and a front holder, wherein the connector housing has an insertion slot for receiving the front holder therein, a terminal receiving chamber for receiving the terminal therein, and a resilient locking arm which is resiliently deformed when pushed by the terminal and is resiliently recovered when the terminal is fully inserted into the terminal receiving chamber. The resilient locking arm has a detection end which is lowered toward the insertion slot when the resilient locking arm is resiliently deformed and is lifted toward the terminal receiving chamber when the resilient locking arm is recovered. The front holder has a holder end facing the detection end, and a stopper which stops the front holder at a provisional locking position where the holder end is spaced apart from the detection end and is pushed into the insertion slot when the front holder passes through the provisional locking position. The front holder, the stopper of which is released, is shifted upward so that the holder end is movable in a direction to abut against the lowered detection end of the resilient locking arm. Thus, a secure locking of the terminal in the connector housing and an incomplete terminal insertion detector is realized, even if there are some dimensional errors for the related parts accompanying the fabrication thereof.
