Plug and receptacle connectors.

摘要

A coaxial plug connector for use as an insert in a first connector housing comprises a first generally cylindrical outer shell (12), a socket (14) centered on the axis of the shell and a sleeve of electrically insulating material between the socket and the shell. The forward end of the insulating sleeve projects beyond the forward end of the socket and has peripheral regions defining a first male frustoconical or other convex face (20), it is used in combination with a coaxial receptacle connector for use as an insert in a second connector housing and has a second generally cylindrical outer shell (36) dimensioned to mate with the first outer shell, a contact pin (38) centered on the axis of the second shell and an insulating sleeve (30) whose forward end is recessed behind the forward end of the contact pin and has regions (44, 46) defining complementary frustoconical faces to those at the forward end of the plug connector. In use the convex face of the plug connector assists in eliminating misalignment between the plug and receptacle during mating of the first and second connector housings.
