  • Connector latch for a housing
    Patent number: 10135182
    Abstract: Connector latch for a housing used to securely hold together a connector apparatus. The connector apparatus has at least a first housing and a second housing. The first housing has the connector latch. The first and second housings can be mated together. Initially, after the connector latch is manufactured, the connector latch is in an undeflected position. After manufacture, the connector latch is subjected to a pre-mating deflection process, in order to deflect the connector latch into a preloaded position. After the pre-mating deflection process has been completed, the connector latch is locked in the preloaded position. The preloaded connector latch provides a number of desirable characteristics, including at least an extra loud “click” sound when the first housing and the second housing are mated together.

  • CONNECTOR POSITION ASSURANCE DEVICE, CONNECTOR SYSTEM AND METHOD FOR OPERATING THE CONNECTOR SYSTEM
    Publication number: 20180316132
    Abstract: A connector position assurance device having multiple features for assuring a full coupling and locking of a female housing with a male housing in a connector system, such that the female housing and male housing are placed into a fully coupled and locked position when the connector position assurance device is moved from a pre-lock position to a full-lock position. When the connector position assurance device is at a full-lock position, a first member on the connector position assurance penetrates a window formed on the female housing, and at least one ledge extending from the connector position assurance device prevents a flexible member of the female housing from being moved downward, providing assurance that the female and male housings are fully coupled and locked together.

  • Electrical connector apparatus having a male housing and a female housing with ribs
    Patent number: 10109955
    Abstract: An electrical connector apparatus with a protected terminal position assurance device (TPA) provided in the male housing and the female housing, the male housing having a TPA for connecting thereto at least a set of terminals, and the female housing having a TPA for connecting thereto at least a set of terminals. Specifically, the male housing and the female housing of the electrical connector apparatus are designed with ribs and other protective features to prevent the TPA from moving from a pre-set position to a final lock position during shipping and/or handling. The ribs and other protective features of the male housing and the female housing ensure a physical barrier from any contact with the TPA which may alter the position of the TPA.
