Abstract
Plug-socket connector apparatus for optical fiber termination comprises first and second plugs and a socket. The first and second plugs are both single ferrule plugs. The socket is a molded interconnect device and a plug holder, and includes terminals located on the bottom face of the socket, first and second bores located at one side of the socket, and first and second retainers. The retainers retain latches formed in the plugs so as to prevent the plugs from falling out of the bores and to restrict rotation angles of the plugs around the axes within predetermined rotation angle ranges, when the plugs is plugged in the bores.

Plug-socket connector apparatus for optical fiber termination, comprising:
- a plug fixed at one end of an optical fiber cable enclosing an optical fiber;
- a socket configured to be mechanically connected with the plug, said socket having a cavity of which bottom faces the end face of the optical fiber projected form the end of the optical fiber cable when mechanically connected with the plug;
- and
- a photoelectric converter including an optical element located on the bottom of the cavity, said converter being provided for the socket;
- wherein the plug is a single ferrule plug comprising:
- a plug-base having a hole into which the end of the optical fiber cable is inserted, said plug-base fixing the end inserted into the hole;
- a circular plug-tip having a pinhole into which the optical fiber projected from the end of the optical fiber cable is inserted;
- and
- at least one latch formed on one part of the side face of the plug-tip;
- wherein the socket further comprises:
- terminals that are located on the bottom face of the socket and are electrically connected with the converter, said terminals being electrically connected with lands of a printed circuit board, respectively when the socket is mounted on the board;
- a bore located at one side of the socket, said bore coming in contact with the remaining part of the side face of the plug-tip so that the plug can rotate around the pinhole when the plug is mechanically connected with the socket;
- and
- a retainer that retains said at least one latch so as to prevent the plug-tip from falling out of the bore and to restrict a rotation angle of the plug around the pinhole within a predetermined rotation angle range, when the plug-tip is plugged in the bore.
