Electrical connector

An electrical connector housing of resilient insulating material including first and second housing parts, the first part having a through cavity for receiving a contact portion of a terminal, and the second part having a through cavity for receiving a wire connecting portion of the terminal, the housing parts being assembled with the cavities in general alignment, the connector housing comprising, interengaging guide means integral with said housing parts including parallel guide rails on one said housing part and cooperating ribs on the other said housing part, wherein said guide rails slidably engage said ribs to allow for relative sliding movement transversely of the cavities between said first and second housing parts to permit adjustment of the alignment between said cavities, said interengaging guide means additionally preventing separation of said first and second housing parts in the direction longitudinal of the cavities, said housing parts being moveable to a relatively offset position in which a portion of said second housing part overlaps an edge of the cavity in said first housing part thereby forming a retaining shoulder for securing and positively engaging a terminal contact therein, and position indexing means for releaseably holding said housing parts in either of two relative positions, one of said positions being said relatively offset position.
