Abstract
Abstract This invention provides a connector which can receive a terminal member easily and positively. In the connector, a retainer 10 is provided on each engaging portion 12 with a guide ramp face 20 which is opposed to a cavity 2 at a temporary locking position. A terminal member 30 is pushed into the cavity 2 when the retainer is at the temporary locking position. The member 30 does not enter into an opening 6 on account of the correcting action of the guide ramp face 20, even if the terminal member 30 is pushed toward the opening 6. After the distal end of the terminal member 30 passes over the guide ramp face 20, and outer periphery of the terminal member 30 is pushed down by a front end of the face 20. Consequently, the terminal member 30 is prevented from entering into the opening 6 and moves in the proper passage.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
302 words
A connector comprising a housing and a retainer, said housing having a rear end, a front end, and housing sides therebetween, each of a plurality of cavities in said housing extending from said rear end to said front end and having an opening at said rear end, each of said cavities adapted to receive a corresponding terminal, ramp faces on said housing adjacent said rear end of at least two of said cavities, said ramp faces adapted to guide said retainer between a temporary locking position and a secured locking position, first engaging elements in said cavities and including elastic lock pieces projecting into said cavities and adapted to engage respective locking holes in said terminals while said retainer is in said temporary position, a guide boss on each of said housing sides slanting parallel to said ramp faces, said retainer having a front facing said rear end, a rear, facing away from said rear end, and retainer sides therebetween, side plates on said retainer sides each having an elongated slot therein, which slot is adapted to receive therein a respective one of said guide bosses, a plurality of engaging portions on said retainer and between said side plates, each of said engaging portions having a guide face parallel and complementary to said elongated slot and adapted to secure terminals in respective ones of said cavities, whereby said retainer, when moving between said temporary position and said secured position, is guided by said ramp face when said guide bosses are received in said elongated slots, thereby to mount said retainer on said housing, said guide faces guiding said terminals as they enter said cavities when said retainer is in said temporary position and moving to said secured position, wherein second engaging elements are adapted to lock said retainer in said secured position.
Claim 2
Dependent Claim

A connector comprising a housing and a retainer, said housing having a rear end, a front end, and housing sides therebetween, each of a plurality of cavities in said housing extending from said rear end to said front end and having an opening at said rear end, each of said cavities adapted to receive a corresponding terminal, ramp faces on said housing adjacent said rear end of at least two of said cavities, said ramp faces adapted to guide said retainer between a temporary locking position and a secured locking position, first engaging elements in said cavities and including elastic lock pieces projecting into said cavities and adapted to engage respective locking holes in said terminals while said retainer is in said temporary position, a guide boss on each of said housing sides slanting parallel to said ramp faces, said retainer having a front facing said rear end, a rear, facing away from said rear end, and retainer sides therebetween, side plates on said retainer sides each having an elongated slot therein, which slot is adapted to receive therein a respective one of said guide bosses, a plurality of engaging portions on said retainer and between said side plates, each of said engaging portions having a guide face parallel and complementary to said elongated slot and adapted to secure terminals in respective ones of said cavities, whereby said retainer, when moving between said temporary position and said secured position, is guided by said ramp face when said guide bosses are received in said elongated slots, thereby to mount said retainer on said housing, said guide faces guiding said terminals as they enter said cavities when said retainer is in said temporary position and moving to said secured position, wherein second engaging elements are adapted to lock said retainer in said secured position.
Claim 3
Dependent Claim
13 words
