Electrical connector with deflectable secondary

摘要

An electrical connector 2 includes a connector housing 4, terminals 40 positioned in the housing 4 and a rear secondary locking member 50. Both the terminals 40 and the secondary locking member are inserted into the housing 4 through the rear end. In a prelatched configuration, the rear secondary locking member 50 provides clearance for terminal insertion. When moved forward to a latched configuration, deflectable tongues 74 engage the terminals 40 from behind to either move the terminals 40 to a fully inserted position or to prevent removal of properly inserted terminal 40. The deflectable tongues 74 include slots in the tongues into which internal housing wall 12 extend when the tongues 74 are inwardly deflected to provide resistance to extraction forces applied to the terminals 40 through wires. The tongues 74 are joined to a locking member body 52 by a thinner connecting section 86 and the rear secondary locking member 50 can be molded by straight pull mold tooling.
