Abstract

A plug connector is attachable with an optical fiber cable and is connectable with a receptacle connector. The receptacle connector comprises a receptacle shell. The plug connector comprises a front holder, a cable holding portion, a rear holder and a coupling member. The front holder is made of metal. The front holder is mated with the receptacle shell when the plug connector is connected with the receptacle connector. The cable holding portion is made of metal. The cable holding portion is configured to hold the optical fiber cable. The rear holder guards the cable holding portion. The rear holder comprises, at least in part, a thermal insulating portion made of non-metal material. The coupling member couples the front holder and the rear holder with each other. Each of the coupling member and the front holder is in contact with the rear holder only on the thermal insulating portion.

First claim

The invention claimed is:

1. A plug connector attachable with an optical fiber cable and connectable with a receptacle connector along a front-rear direction, wherein:
the receptacle connector comprises a receptacle shell;
the plug connector comprises a front holder, a cable holding portion, a rear holder and a coupling member;
the front holder is made of metal;
the front holder is mated with the receptacle shell when the plug connector is connected with the receptacle connector;
the cable holding portion is made of metal;
the cable holding portion is configured to hold the optical fiber cable;
the rear holder guards the cable holding portion;
the rear holder comprises, at least in part, a thermal insulating portion made of non-metal material;
the coupling member couples the front holder and the rear holder with each other; and
each of the coupling member and the front holder is in contact with the rear holder only on the thermal insulating portion;
the coupling member is a coupling nut; and
the coupling member is attached to an outer circumference of the rear holder so as to be rotatable on the outer circumference of the rear holder and movable on the outer circumference of the rear holder in the front-rear direction.

2. The plug connector as recited in claim 1 , wherein the rear holder is made of resin.

3. The plug connector as recited in claim 1 , wherein:
the plug connector further comprises an optical module with a photoelectric conversion portion; and
the photoelectric conversion portion converts optical signals to electrical signals and vice versa.
