Abstract

The optical connector has the receptacle which is fastened to the board provided with the optical waveguides and has the plug which holds the optical fibers and is connected to the receptacle. The receptacle has the positioning member which positions the optical fibers to the optical waveguides to connect them optically by abutment against the plug and has the fastening member which is fastened to the board and fastens the positioning member to the optical waveguides.

First claim

The invention claimed is:

1. An optical connector, comprising:
a first connector part which is fastened to a base provided with a first optical transmission line; and
a second connector part which holds a second optical transmission line and is connected to the first connector part, wherein
the first connector part comprises:
a positioning member is on the first optical transmission line, the positioning member which is configured to position the second optical transmission line and optically connects the second optical transmission line with the first optical transmission line, and
a fastening member which is fastened to the base and fastens the positioning member with respect to the first optical transmission line, and
a first elastic member arranged between the fastening member and the positioning member, and pressing the positioning member to the base side in a direction perpendicular to the first optical transmission line.

2. The optical connector according to claim 1 , wherein:
the positioning member comprises a first opening in which the second connector part is fit in an abutment direction of the first optical transmission line and the second optical transmission line.

3. The optical connector according to claim 2 , wherein:
an inner circumferential surface of the first opening comprises a plurality of projections, the plurality of projections abutting against a portion of the outer circumferential surface of the second connector part and positioning the second connector part.

4. The optical connector according to claim 2 , wherein:
the first opening becomes larger toward an inlet side in the abutment direction.

5. The optical connector according to claim 2 , wherein:
the fastening member comprises a guide portion which guides the second connector part to the first opening, and
the guide portion comprises a second opening in which the second connector part is inserted, the second opening becoming broader toward the inlet side in the abutment direction.

6. The optical connector according to claim 1 , wherein: the first connector part comprises a plurality of the first elastic members.

7. An optical transmission module, comprising:
a first optical transmission line;
a base in which the first optical transmission line is provided;
a second optical transmission line;
a first connector part which is fastened to the base; and
a second connector part which holds the second optical transmission line and is connected to the first connector part,
wherein the first connector part comprises:
a positioning member is on the first optical transmission line, the positioning member which is configured to position the second optical transmission line and optically connects the second optical transmission line with the first optical transmission line, and
a fastening member which is fastened to the base and fastens the positioning member with respect to the first optical transmission line, and
a first elastic member arranged between the fastening member and the positioning member, and pressing the positioning member to the base side in a direction perpendicular to the first optical transmission line.

8. The optical connector according to claim 3 , wherein:
the first opening becomes larger toward an inlet side in the abutment direction.

9. The optical connector according to claim 3 , wherein:
the fastening member comprises a guide portion which guides the second connector part to the first opening, and
the guide portion comprises a second opening in which the second connector part is inserted, the second opening becoming broader toward the inlet side in the abutment direction.

10. The optical connector according to claim 4 , wherein:
the fastening member comprises a guide portion which guides the second connector part to the first opening, and
the guide portion comprises a second opening in which the second connector part is inserted, the second opening becoming broader toward the inlet side in the abutment direction.

11. The optical connector according to claim 8 , wherein:
the fastening member comprises a guide portion which guides the second connector part to the first opening, and
the guide portion comprises a second opening in which the second connector part is inserted, the second opening becoming broader toward the inlet side in the abutment direction.

12. The optical connector according to claim 2 , wherein:
the first connector part comprises a plurality of the first elastic members.

13. The optical connector according to claim 3 , wherein:
the first connector part comprises a plurality of the first elastic members.
