Abstract

An optoelectrical connector is composed of a plug to which a wire and an optical fiber are assembled and a receptacle to which the plug is inserted and connected. A receptacle includes insulation sleeves and conductive contacts in openings of receptacle housings, and plugs include a ferrule assembled bodies which are composed of an insulation ferrule which holds an optical fiber and a conductive cylindrical member which holds the ferrule and to which a wire is assembled, in an opening of the plug housing. When the plugs are inserted into the receptacle, the contacts and the cylindrical member contact with each other and the ferrules are inserted into the sleeves. Parts which serve electrical connection are not exposed.

Claims

1. An optoelectrical connector, comprising:

a plug to which a wire and an optical fiber are assembled; and

a receptacle into which the plug is inserted;

wherein

the receptacle includes an insulation sleeve and a conductive contact in an opening of a receptacle housing thereof,

the plug includes a ferrule assembled body that is composed of an insulation ferrule that holds the optical fiber and a conductive cylindrical member that holds the insulation ferrule and to which the wire is assembled, in an opening of a plug housing thereof, and

when the plug is inserted into the receptacle, the conductive contact and the conductive cylindrical member contact with each other and the insulation ferrule is inserted into the insulation sleeve.

2. The optoelectrical connector according to claim 1, wherein the receptacle is provided to a photoelectric composite device.

3. The optoelectrical connector according to claim 1 or 2, wherein the conductive contact has a cantilevered shape that protrudes toward an end of the opening of the receptacle housing, and one of an insertion hole or an insertion groove for the conductive contact is provided to the plug housing.

4. The optoelectrical connector according to claim 3, wherein

external dimensions of the plug and external dimensions of the receptacle are identical to the IEC61754-20 standard,

the plug has one of one to four insertion holes and one to four insertion grooves, and

the receptacle has conductive contacts corresponding to the number of one of the insertion holes or the insertion grooves.

5. The optoelectrical connector according to claim 1 or 2, wherein the receptacle housing has a convex part in the opening thereof, and the plug housing has a concave part corresponding to the convex part, in the opening thereof.

6. The optoelectrical connector according to claim 3, wherein the receptacle housing has a convex part in the opening thereof, and the plug housing has a concave part corresponding to the convex part, in the opening thereof.

7. The optoelectrical connector according to claim 4, wherein the receptacle housing has a convex part in the opening thereof, and the plug housing has a concave part corresponding to the convex part, in the opening thereof.
