Abstract
The invention reduces the mold costs of a connector provided with an incorrect fitting preventing means. Sub-connectors 20A and 20B, which are respectively fitted into fitting cavities 11A and 11B of a frame 10, are each provided with a connector housing 21, and a cover 45A and 45B respectively. Protrusions 49A and 49B, which function as incorrect fitting preventing members, are formed on the covers 45A and 45B respectively. The connector housings 21, which house terminal fittings 30, have a complex shape. In contrast, the covers 45A and 45B, each of which merely maintains a collective rubber stopper 40 in position, are simple in shape and consequently the mold cost thereof is low. The components provided with the protrusions 49A and 49B are molded as a plurality of types and yet have lower mold costs.
Claims14
An electrical connector comprising a frame defining a cavity therein, said cavity having an anterior end and a posterior end, and an insert having an anterior end and a posterior end, said anterior end of said insert insertable into a posterior end of said cavity in a close fitting manner, an inner circumference of said cavity and an outer circumference of said insert having mutually engageable discontinuities adapted to prevent incorrect fitting of said insert in said cavity when said anterior end of said insert is inserted into said posterior end of said cavity, wherein said insert comprises a housing adapted to receive electrical terminal fittings, and an orientation member separable from and attachable to said housing, the discontinuity of said insert being provided on said orientation member, said housing including a plurality of openings adapted to receive electrical terminals, and said orientation member including corresponding apertures for wires of said terminals.
An electrical connector comprising a frame defining a cavity therein, said cavity having an anterior end and a posterior end, and an insert having an anterior end and a posterior end, said anterior end of said insert insertable into a posterior end of said cavity in a close fitting manner, an inner circumference of said cavity and an outer circumference of said insert having mutually engageable discontinuities adapted to prevent incorrect fitting of said insert in said cavity when said anterior end of said insert is inserted into said posterior end of said cavity, wherein said insert comprises a housing adapted to receive electrical terminal fittings, and an orientation member separable from and attachable to said housing, the discontinuity of said insert being provided on said orientation member, and a resilient seal between said housing and said orientation member, said seal engaging the inner circumference of said cavity.
