Abstract: Various electrical connector assemblies are disclosed. The electrical connector assembly can include a pin and a socket. An outer surface of the pin can have an external thread and an annular groove that has an outside diameter that is less than an outside diameter of an adjacent leading flange. The socket can have an internal thread that mates with the external thread on the pin. The connector can comprise independent securing features, such as a threaded connection and a ball detent connection. The connector can be configured such that disengagement of the first connection feature results in disconnection of mating electrical contacts of the pin and socket. In some variants, the second connection feature remains engaged and/or is disengaged independently of the first connection feature.
