Problems solved by technology

[0004] However, some known CPA members are prone to failure by allowing premature and inadvertent movement of the CPA member into the locked position before the connector is fully mated
This premature actuation of the CPA member may be caused by forces acting on the CPA member that overcome, overstress and / or damage the relatively weak detent features designed to stop the CPA member from premature activation of

Embodiment Construction

[0019] Embodiments disclosed herein provide electrical connectors that include connector position assurance (CPA) elements. The CPA element is movable relative to the housing of the electrical connector. The CPA element is a mechanism for verifying that an electrical connector is fully mated with a corresponding connection connector. The CPA element provides sensory feedback (eg, via sight, sound, and / or touch) to an operator or robotic machine mating the connector. For example, the ability to unrestricted transition of the CPA element relative to the housing from the pre-locked position to the locked position after coupling the mating connector to the housing of the electrical connector provides an indication or notification that the two connectors are fully mated.

[0020] In one or more embodiments described herein, the CPA element and housing of the electrical connector are designed to provide various technical effects. One technical effect is the ability to inhibit, if ...

Abstract

Electrical connector (102) includes a housing (110) and a connector position assurance (CPA) element (112) mounted to the housing. The housing has a latch (140) configured to secure a mating connector(104) to the electrical connector. The CPA element includes a base (302) and an arm (304) extending therefrom. The CPA element is translatable relative to the housing between a pre-lock position anda lock position. As the CPA element is moved from the pre-lock position towards the lock position prior to the latch securing the mating connector, the arm of the CPA element engages the latch and deflects the latch away from a resting position with an increasing amount of deflection until the base of the CPA element abuts against a landing pad (222) of the housing to block further movement of theCPA element towards the lock position.

Description

technical field [0001] The subject matter herein relates generally to electrical connectors that provide connector position assurance. Background technique [0002] Some electrical connectors have a latch feature configured to releasably secure the electrical connector to a mating electrical connector against a pull-out force that would pull the connectors apart and break the conductive path therebetween. When mating two connectors, due to the small physical size of the connectors and / or the presence of other parts that impede the view and accessibility of the connectors. It may be difficult for an operator to determine if the two connectors are fully mated so that the complementary latching features are properly engaged. Some connector systems utilize a connector position assurance (CPA) feature, which is designed as a means of ensuring correct and complete mating of the connectors. [0003] Some CPA members are movable between a pre-locked position and a locked position....
