Abstract

An optical connector comprising a connector body, an enclosure that is a slit-shaped hole formed from one surface of the connector body into the connector body and accommodates a sheet-like optical waveguide with a tip of the optical waveguide abutting against a bottom of the hole, and a pressing section that is provided on a first surface of the enclosure facing a sheet surface of the enclosed optical waveguide and presses the enclosed optical waveguide toward a second surface of the enclosure facing the first surface so as to bring the enclosed optical waveguide into contact with the second surface.

First claim

What is claimed is:

1. An optical connector comprising:
a connector body;
an enclosure that is a slit-shaped hole formed from one surface of the connector body into the connector body, and accommodates a sheet-like optical waveguide with a tip of the optical waveguide abutting against a bottom of the hole;
a pressing section that is provided on a first surface of the enclosure facing a sheet surface of the enclosed optical waveguide, and presses the enclosed optical waveguide toward a second surface of the enclosure facing the first surface so as to bring the enclosed optical waveguide into contact with the second surface; and
a plurality of micro-lenses provided on a second surface of the connector body opposite to the bottom of the hole, and aligned along a plane parallel to the second surface of the enclosure.

2. The optical connector according to claim 1 , wherein the pressing section presses a position at the enclosed optical waveguide in which no core is provided, or a position at the enclosed optical waveguide in which a core not used for transmitting optical signals is provided.

3. The optical connector according to claim 1 , further comprising a projection that is provided on a third surface of the enclosure located between the first surface and the second surface, and pushes the enclosed optical waveguide toward a fourth surface facing the third surface so as to bring the enclosed optical waveguide into contact with the fourth surface.

4. The optical connector according to claim 3 , wherein at least one of the pressing section and the projection is elastic.

5. The optical connector according to claim 1 , wherein the optical waveguide is deformed by being pressed by the pressing section.

6. The optical connector according to claim 2 , further comprising a projection that is provided on a third surface of the enclosure located between the first surface and the second surface, and pushes the enclosed optical waveguide toward a fourth surface facing the third surface so as to bring the enclosed optical waveguide into contact with the fourth surface.

7. The optical connector according to claim 6 , wherein at least one of the pressing section and the projection is elastic.
