  • Publication number: 20240162648
    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: 11831098
    Abstract: A method for improving clearance and creepage in a male or female high voltage connector assembly using a male terminal position assurance (TPA) device. The high voltage connector assembly is suitable for high voltage electrical terminals. The method includes the steps of allowing a clearance and creepage or electrical path to extend from at least a high voltage electrical terminal to a conductive male outer housing, and or between another terminal using a male or a female TPA device. The TPA device is inserted in the high voltage connector assembly, whereby a clearance and creepage or electrical path extends from the high voltage electrical terminal along at least a surface of the TPA device and to the male outer housing of the high voltage connector assembly or from the high voltage electrical terminal to another high voltage electrical terminal in using the male and or female TPA device.

  • Patent number: 11777252
    Abstract: A manufacturing method for assembling a high voltage vertical disk ferrule, the ferrule being stamped and having a vertical disk-like structure, which is not necessarily round or does not necessarily have any roundness. The high voltage disk ferrule has an opening residing and traveling over the wire core and/or a wire braided shield, to which an end portion of the wire braided shield is affixed thereto the ferrule, or between two ferrules, such that a portion of the wire braided shield is flared and substantially perpendicular to the direction along which the wire core extends. The high voltage vertical disk ferrule slides over the core insulation, towards the outer insulation when the wire is pushed. The end portion/flared portion of the braided shield and the high voltage vertical disk ferrule, or the end portion/flared portion of the braided shield between at least two high voltage vertical disk ferrules are soldered, welded, or brazed together.

  • Patent number: 11670892
    Abstract: A high voltage vertical disk ferrule, and method for assembling thereof, the ferrule being stamped and having a vertical disk-like structure, which is not necessarily round or does not necessarily have any roundness. The high voltage vertical disk ferrule has an opening residing and traveling over the wire core and/or a wire braided shield, to which an end portion of the wire braided shield is affixed to the ferrule, or between two ferrules, such that a portion of the wire braided shield is flared and substantially perpendicular to the direction along which the wire core extends. The high voltage vertical disk slides over the core insulation, and towards the outer insulation when the wire is pushed. The wire braided shield develops a natural spring force against the ferrule, and causes it to be accordioned, pleated, or folded against itself, and therefore pushes the vertical disk ferrule forward.

  • Publication number: 20220320804
    Abstract: The present invention involves a method for reducing the effect of electromagnetic interference (EMI) by providing EMI protection to a high voltage connector assembly, by employing a conductive outer housing, having a conductive tab or plurality of conductive tabs, the conductive outer housing also accommodating a seal (seal spring), a second outer housing, and a conductive third outer housing. The tabs being conductive coated to provide an element or portion of a grounding scheme for a connector assembly containing the outer housing. The conductive tabs make substantial contact with the conductive third outer housing and complete a portion of the connector assembly grounding scheme. The seal spring provides more force, additional force, for higher contact pressure with the third outer housing than would be present without the seal spring, resulting in better electrical conductivity between a conductive tab and the conductive third outer housing when in use.
