Electrical connector having a terminal position assurance device
First Claim
1. An electrical connector comprising:
- a housing body having an outer wall which defines a passageway for receiving a contact, the outer wall having a deflectable contact retention member for retaining the contact within the passageway; and
a terminal position assurance member having a locking surface and a prelatch surface, the terminal position assurance member being movable between a prelatch position and a latch position, whereby when the terminal position assurance member is in the prelatch position the prelatch surface is positioned adjacent the contact retention member but distanced from the contact retention member by a recess to accommodate deflection of the contact retention member and insertion of the contact into the passageway, and when in the latch position the locking surface is adjacent to and in contact with the contact retention member, thereby preventing deflection of the contact retention member and removal of the contact from the passageway.

Abstract
The invention is directed to an electrical connector having a housing body with a contact receiving passage therein. The contact receiving passage has a contact retention arm for securing a contact within the passage. The contact retention arm forms the outer wall of the body. A terminal position assurance member has an outer wall with an inner shoulder and a locking surface. The outer wall is received around the contact retention arm. The terminal position assurance member has a first position in which the terminal position assurance member forms a space behind the contact retention arm. The terminal position assurance member has a second position wherein the locking surface is received behind the contact retention arm thereby preventing deflection of the contact retention arm.

9. An electrical connector comprising:
-
a housing body having at least one contact receiving passageway bound by an outer wall, the outer wall having at least one contact retention member aligned with each contact receiving passageway for releasably engaging each contact; and a terminal position assurance member about the housing body movable between a prelatch position and a latch position, the terminal position assurance member having a prelatch surface and a locking surface, such that when the terminal position assurance member is in the prelatch position, the prelatch surface is located adjacent the contact retention member but distanced from the contact retention member by a recess so as to accommodate deflection thereof and insertion of the contact into the passageway, and when the terminal position assurance member is in the latch position, the locking surface is located adjacent to and in contact with the latch member thereby preventing deflection thereof and removal of the contact from the passageway. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
