  • Publication number: 20260058386
    Abstract: A compressible electrical contact, manufactured from a tube, includes a first contact end, a second contact end opposing the first contact end, and a medial portion disposed between the first contact end and the second contact end. The medial portion includes a plurality of divaricated cut sections based on at least one divaricating pattern cut into the tube. The at least one divaricating pattern preferably includes an upper tapered section and a lower tapered section such that a plurality of tapered slots are formed after the tube is cut and when the compressible electrical contact is substantially compressed.

  • Publication number: 20250118910
    Abstract: Various configurations of compressible electrical assemblies and connector systems are disclosed herein. Each variation of the compressible electrical assemblies includes at least one dielectric, an inner conductor and an outer conductor. Each inner and outer conductor may be configured as a compressible contact. One embodiment of a compressible electrical assembly includes an inner compressible contact, and outer compressible contact and a dielectric disposed at least partially between the inner compressible contact and the outer compressible contact. Each compressible contact also has a divaricated-cut section with a plurality of cuts defined by at least one cut angle measured between a pair of opposing inner surfaces.

  • Patent number: 11316294
    Abstract: Miniaturized electrical connector systems are disclosed herein. In exemplary aspects disclosed herein, the connector system includes a twinaxial female connector having a housing and at least one dielectric positioned therein. The at least one dielectric defines two parallel channels configured to receive at least a portion of two conductors of a twinaxial cable. The twinaxial female connector includes an oval interface configured to orient and align the conductors of the twinaxial cable with mating pins of a male connector. The twinaxial female connector further includes two spring-type interconnects positioned within the oval interface, each configured to directly contact a conductor of the twinaxial cable and a mating pin of the male connector. The twinaxial female connector further includes a retaining clip attached to an exterior of the housing with a lever arm biased towards and pivotable from an engaged orientation. Such features reduce the manufacturing complexity, cost, and overall size.
