  • Patent number: 11699869
    Abstract: An electrical female terminal for mating with a connector assembly generally including a main body, a two-bodied spring, and a wire fastening portion. A protrusion extends from an unattached end portion of the lever member, the protrusion having faces angled relative to each other to efficiently deflect the lever member upwards when the protrusion interacts with an internal protrusion of a housing or a connector assembly. A top portion of the retainer member of the electrical female terminal, located above the two-bodied spring, has a dimple portion. The terminal face or leading end portion of the electrical female terminal is prevented from damaging or cutting a silicone seal. The overstress feature of the tang member of the lever is improved upon by relocating and reshaping the protruding member thereof. The configuration or shape of the cross-section across the upper portion and the support member at the front end portion of the main body of the electrical female terminal is substantially U-shaped.

  • Publication number: 20230198173
    Abstract: An electrical male terminal of this invention includes a clamp or crimp area, a main body, and a blade. Protruding members and support members of the main body act as overstress protection. A panel shield member protects a protruding guide member. In another embodiment of this invention, a protruding member extends from a first support member of the main body, and a cut-out portion at the lower portion of the main body accommodates therein the protruding member to prevent the tang member fr©m inadvertently or accidentally rotating relative to the lower portion of the main body.

  • 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: 20230170643
    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 a conductive female housing and connector assembly. The seal spring compresses and provides adequate spring force against a disk ferrule assembly, pressing the disk ferrule assembly, with a wire shield, against a conductive female outer housing, providing a grounding scheme for the connector assembly. The seal spring also seals against the female outer housing and a wire.

  • Patent number: 11658426
    Abstract: An Insulation Displacement Contact Compliant connector system (IDCC) which includes a housing, header pins, and a Printed Circuit Board (PCB). Each header pin has at least a single barb to be retained into the housing. Each pin has a blade for contacting a wire. A compliant feature on the pin retains itself into holes in the PCB. The housing has a negative space similarly shaped to the pin. The housing includes a strain relief which provides a lead-in for a wire. When the system is fully assembled, the pins reside in the housing, and exit through the housing and into and through respective holes in the PCB. A wire can be inserted into the housing once the pins reside in the housing. There are several options for the assembly process including a) a pin-to-housing insertion process; b) a housing assembly-to-PCB process or a connector-to-PCB process; and c) a wired housing assembly-to-PCB assembly process or a wire harness-to-PCB assembly process.

  • Publication number: 20230155312
    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.

  • 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.
