Connector with integrally molded resin portions of different materials

1 . A connector, comprising:

a primary molding portion made of a primary resin material; and

a secondary molding portion made of a secondary resin material,

wherein the secondary molding portion being provided relatively movably with respect to the primary molding portion,

wherein the primary resin material and the secondary resin material being resin materials unbondable to each other so that the integrally molded primary molding portion and secondary molding portion are dividable,

wherein the primary molding portion and the secondary molding portion are integrally molded together by two-color molding such that the primary molding portion and the secondary molding portion are separable from each other along a boundary surface, and

wherein the primary molding portion includes a housing-side cavity having an open portion in a lower end thereof, the open portion forming the boundary surface between the housing-side cavity and the secondary molding portion.

2 . The connector of claim 1 , wherein the primary molding portion includes a locking portion, the secondary molding portion includes a lock receiving portion for restricting a relative movement of the secondary molding portion by being locked to the locking portion, and the locking portion and the lock receiving portion extend in a direction intersecting a moving direction of the secondary molding portion and face and contact each other in parallel.

3 . The connector of claim 2 , wherein the primary resin material and the secondary resin material are different resin materials, the primary molding portion is a connector housing, the secondary molding portion is a retainer, the connector housing includes a resiliently deformable locking lance for primarily locking a terminal fitting, and the retainer includes a retaining portion for secondarily locking the terminal fitting.

4 . The connector of claim 3 , wherein the connector housing includes a retainer accommodation recess for accommodating the retainer, and the retainer accommodation recess is open from a surface side facing the retainer in the moving direction of the retainer to a surface side facing the terminal fitting in an inserting direction of the terminal fitting.

5 . The connector of claim 4 , wherein the connector housing is shaped to be cut in an entire rear-lower part thereof in the retainer accommodation recess if the surface side facing the retainer is a lower surface side of the connector housing and the surface side facing the terminal fitting is a rear surface side of the connector housing.

6 . The connector of claim 5 , wherein the connector housing includes a housing-side cavity, the retainer includes a retainer-side cavity, the retainer-side cavity and the housing-side cavity communicate in a front-rear direction and form an insertion path for the terminal fitting, and a wall surface forming the insertion path with the retainer assembled at a temporary locking position with respect to the connector housing is continuous from the retainer-side cavity to the housing-side cavity without forming any step.
