Abstract

A connector module is provided that includes a first connector housing, a second connector housing and a connector positive assurance member. Insertion of the first housing into the second housing will cause a latching mechanism located within the assembled first and second housings to latch the housings together so that they can not be readily disengaged. When the first and second housings are fully engaged in this manner, the connector positive assurance member may be moved from a first position to a second position to assure complete engagement has been effected and to lock the housings together. If the first and second housings are not filly engaged, the connector positive assurance member can not be moved from such first position to such second position.

11. The connector module of claim 10 wherein said first arm comprises a first distal end surface and an opposite second distal end surface, said first distal end surface being engagable with a first surface of said engagement member in said locked mode so as to prevent movement of said positive assurance member in a direction opposite to said locking direction, and said second distal end surface being engagable with an opposite second surface of said engagement member in a pre-locked mode, said second distal end surface and said second surface of said engagement member, and said first and second detents and respective first and second detent abutment members, being structured an arranged to resist movement of said positive assurance member in the direction of said longitudinal axis except in said engaged mode.

12. The connector module of claim 11 wherein said lug and said first abutment member are structured and arranged such that said lug is engagable with said first abutment member to displace said first abutment member away from said longitudinal axis to permit movement of said positive assurance member in said locking direction.
