  • Publication number: 20220316594
    Abstract: The seal spring of the present invention has a dual functionality. The seal spring provides both a sealing property and spring function in use within an electrical connector system, which is accomplished by its elastomeric qualities. The seal spring is preferably comprised of Silicone, EPDM rubber or materials and compositions that provide similar performance during use, or the like. The seal spring of the present invention is not limited or defined into a spring section or a seal section by its geometry. Shown is an implementation of the seal spring within an outer housing and connector assembly. The seal spring compresses and provides adequate spring force against a tab or tabs within the outer housing. The seal spring also functions as an interface seal and an environmental seal during use. The seal spring is, substantially, in its entirety, of a contiguous and continuous single construction. No part or section of the seal spring is made up of welded, soldered, or brazen part or section.

  • Patent number: 11456553
    Abstract: A low profile high voltage connector, having a minimal height and meeting high voltage requirements and a method of assembling thereof, includes a male housing and a female housing, and further includes a terminal position assurance (TPA) device and a connector position assurance (CPA) device, the TPA device ensuring that a terminal, housed within the female housing, provides a secondary lock, so as to ensure that the terminal is secured or locked within the female housing. The CPA device assures that the male and female housings remain locked and inseparable from each other. The terminal is housed within the female housing in such a way as to have the female housing, engaged within the male housing, to meet a minimal height requirement. Each of the TPA device and the CPA device functions in a pre-lock position or a full-lock position when engaging with the low profile high voltage connector.

  • Patent number: 11404823
    Abstract: A connector system that uses an elastomeric suspension to provide compliance for mating alignment and to provide an axial compression force of the two connector halves. This connector system uses a first connector half mounted to a body and a second connected half that comprises a rigidly mounted outer housing with elastomeric suspension element(s) that suspend an inner connector housing. The outer housing could be mounted to another body in such a way that the mating process of the two connector halves might not be observable. The axial compression force of the two connector halves keeps them tightly mated.
