Abstract
Abstract A connector includes a retainer that can be provisionally retained by a connector positioning device. Each retainer is integrally molded on a connector housing through hinge pieces, and can be attached to the connector housing by fitting a guide slot of each of the retaining pieces on a guide projection. Therefore, the retainer can be attached by a pusher that pushes the retainer in a direction perpendicular to the connector housing. At this time, for attaching the retainer to a provisionally-retained position, there is provided a guide for holding the retainer in such a posture that the retainer can be attached in the provisionally-retained position.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
220 words
A connector comprising an integral retainer that is molded on a connector housing through flexible hinge pieces, wherein: said connector housing comprises tubular shaped terminal receiving chambers for receiving metal terminals that are each connected to an end of a wire, retainer insertion holes open to one side of said terminal receiving chambers, and recesses formed by substantially parallel walls within the connector housing for receiving said hinge pieces; said retainer includes a retainer body having terminal lock portions each insertable into respective ones of said retainer insertion holes to retain and engage a side of each said inserted metal terminal, and retaining pieces formed respectively at opposite ends of said retainer body in such a manner that said retainer has a gate-shape, said retaining pieces being attached respectively to opposite sides of said connector housing; and said retainer is attachable in a provisionally-retained position where said hinge pieces are protectively disposed within said recesses in said connector housing, said retaining pieces are attached to said connector housing, and terminal lock portions formed on said connector housing being disengaged from said metal terminals, said retainer also being attachable in a completely-retained position where said terminal lock portions engage with respective said metal terminals, said retainer being slidingly movable along an outer surface of said connector housing into said completely-retained position.
Claim 2
Dependent Claim

A connector comprising an integral retainer that is molded on a connector housing through flexible hinge pieces, wherein: said connector housing comprises tubular shaped terminal receiving chambers for receiving metal terminals that are each connected to an end of a wire, retainer insertion holes open to one side of said terminal receiving chambers, and recesses formed by substantially parallel walls within the connector housing for receiving said hinge pieces; said retainer includes a retainer body having terminal lock portions each insertable into respective ones of said retainer insertion holes to retain and engage a side of each said inserted metal terminal, and retaining pieces formed respectively at opposite ends of said retainer body in such a manner that said retainer has a gate-shape, said retaining pieces being attached respectively to opposite sides of said connector housing; and said retainer is attachable in a provisionally-retained position where said hinge pieces are protectively disposed within said recesses in said connector housing, said retaining pieces are attached to said connector housing, and terminal lock portions formed on said connector housing being disengaged from said metal terminals, said retainer also being attachable in a completely-retained position where said terminal lock portions engage with respective said metal terminals, said retainer being slidingly movable along an outer surface of said connector housing into said completely-retained position.
Claim 3
Dependent Claim
142 words
A connector comprising: a connector housing having terminal receiving chambers communicating with retainer insertion holes, at least one recess formed by substantially parallel walls in a central portion within outer surfaces of the connector housing and guide projections formed on opposite sides of the connector housing; and a retainer flexibly molded on the connector housing through at least one flexible hinge piece adapted to fit within the at least one recess, said retainer including lock pieces that are engageable with the retainer insertion holes, and retaining pieces formed at each end of the retainer, said retaining pieces each having a guide slot that engages one of the guide projections when the lock pieces assume a provisionally retained position such that said at least one flexible hinge piece is disposed within said at least one recess during transportation to a terminal insertion station.
Claim 4
Dependent Claim
142 words
A connector comprising: a connector housing having terminal receiving chambers communicating with retainer insertion holes, at least one recess formed by substantially parallel walls in a central portion within outer surfaces of the connector housing and guide projections formed on opposite sides of the connector housing; and a retainer flexibly molded on the connector housing through at least one flexible hinge piece adapted to fit within the at least one recess, said retainer including lock pieces that are engageable with the retainer insertion holes, and retaining pieces formed at each end of the retainer, said retaining pieces each having a guide slot that engages one of the guide projections when the lock pieces assume a provisionally retained position such that said at least one flexible hinge piece is disposed within said at least one recess during transportation to a terminal insertion station.
Claim 5
Dependent Claim
166 words
A connector comprising: a connector housing having terminal receiving chambers communicating with retainer insertion holes, a guide projection formed on each of opposite sides of the connector housing, and a lock projection formed on said each of said opposite sides adjacent said guide projection; and a retainer flexibly molded on the connector housing through flexible hinge pieces, said retainer including lock pieces that are engageable with the retainer insertion holes, and retaining pieces formed at each end of the retainer outside the flexible hinge pieces, said retaining pieces each having a guide slot that 1) engages the corresponding guide projection when the retainer assumes a provisionally retained position while being transported to a terminal insertion station, and 2) engages the corresponding guide projection and the adjacent lock projection when the retainer assumes a completely retained position, and the lock pieces thus secure terminals that have been inserted at said terminal insertion station, said connector housing further including recesses receiving said flexible hinge pieces during said transportation.
Claim 6
Dependent Claim
166 words
A connector comprising: a connector housing having terminal receiving chambers communicating with retainer insertion holes, a guide projection formed on each of opposite sides of the connector housing, and a lock projection formed on said each of said opposite sides adjacent said guide projection; and a retainer flexibly molded on the connector housing through flexible hinge pieces, said retainer including lock pieces that are engageable with the retainer insertion holes, and retaining pieces formed at each end of the retainer outside the flexible hinge pieces, said retaining pieces each having a guide slot that 1) engages the corresponding guide projection when the retainer assumes a provisionally retained position while being transported to a terminal insertion station, and 2) engages the corresponding guide projection and the adjacent lock projection when the retainer assumes a completely retained position, and the lock pieces thus secure terminals that have been inserted at said terminal insertion station, said connector housing further including recesses receiving said flexible hinge pieces during said transportation.
Claim 7
Dependent Claim

The connector of claim 3, wherein the flexible hinge pieces are protectively disposed within the recesses.
Claim 11
Dependent Claim

Claim 13
Independent Claim
110 words
A method for connecting terminals to a connector having a connector housing and a pair of retainers that are hingeably connected to the connector housing, comprising the steps of: positioning the retainers in a provisional retained position such that flexible hinge pieces formed on the retainers are disposed within protective recesses provided within outer surfaces of the connector housing between terminal receiving chambers of said connector housing; inserting terminals into said terminal receiving chambers to effect primary retaining of the terminals while the retainers are in said provisionally retained position; and shifting the retainers toward the connector housing until lock pieces of the retainers effect secondary retaining of the terminals.
