Miniaturized electrical connector systems

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.
