Abstract
Abstract A latching mechanism and connector position assurance (CPA) system is provided for use with a two-part electrical connector having a first connector half which may be assembled to a second connector half. A raised stop is located on the first connector half, and the stop includes a ramp facing the second connector half during assembly of the first and second halves. A latch pocket is located on the second connector half, and the latch pocket includes an upperwall, a pair of sidewalls, and a deck. A latch member made of resilient metal is located within the latch pocket, and the latch member includes a latch arm having an aperture capable of receiving the raised stop. The latch arm is spring biased toward the deck, so that when the first connector half is assembled to the second connector half, the raised stop enters the aperture. The raised stop is retained within the aperture, and the first and second connector halves are thereby latched together. A CPA device is insertable into the latch pocket for contacting the latch and for preventing the latch arm from being raised to release said stop from said aperture. The CPA device can not be moved to the full forward position unless the connector halves are properly assembled and latched.

Claim 9
Dependent Claim
210 words
A combination of a connector, a latch mechanism, and a CPA device, said combination comprising: a first connector half mateable with a second connector half, a raised stop located on said first connector half, said raised stop having a ramped side; a latch located on said second connector half, whereby when said connector halves are mated, a portion of said latch slides up and over said ramped side for engaging said raised stop, thereby latching said connector halves together; and a CPA device mounted on said second connector half and being movable from an unlocked position to a locked position, said CPA device having a main body with a centrally-located elongate flexible arm extending therefrom, said flexible arm having a distal securing member located on the distal end thereof, whereby, following mating of the first and second halves of the connector, if the connector halves are not properly assembled or not properly latched, said distal securing member will prevent movement of the CPA device to said locked position, and further whereby, if the connector halves are properly assembled and latched, the distal securing member will be able to slide up and over said ramped side of said raised stop and will thereby retain the CPA device in the locked position.
