Abstract

An optical connector includes a board including an element that performs conversion between an electric signal and light, a first ferrule and a second ferrule that are butted against each other, an optical waveguide that optically connects the first ferrule with the element, and a guide that guides the optical waveguide disposed between the first ferrule and the element.

First claim

What is claimed is:

1. An optical connector, comprising:
a housing;
a ferrule attached to the housing, an optical waveguide being connected to the ferrule; and
a guide that guides the optical waveguide, the guide being housed in the housing and protruding from an inner bottom surface of the housing in a direction perpendicular to the inner bottom surface, wherein
the guide includes an upper part, an inclined part, and a first bent part connecting the upper part and the inclined part; and
a height of the upper part of the guide is equal to a distance in height between a part of the optical waveguide coming out from the ferrule and the inner bottom surface of the housing.

2. The optical connector as claimed in claim 1 , wherein the guide further includes a lower part and a second bent part connecting the inclined part and the lower part.

3. The optical connector as claimed in claim 1 , wherein
the housing includes an attaching part to which the ferrule is attached; and
a step is formed between the attaching part and the inner bottom surface.

4. The optical connector as claimed in claim 1 , wherein the housing and the guide are formed as a monolithic part.

5. An optical connector, comprising:
a ferrule;
an optical waveguide extending from the ferrule;
a guide that is attached to the ferrule and guides the optical waveguide; and
a guide pin connected to the guide, wherein
the guide includes an upper part, an inclined part, and a bent part connecting the upper part and the inclined part; and
the ferrule includes a hole into which the guide pin is inserted.

6. The optical connector as claimed in claim 5 , wherein the guide and the guide pin are formed as a monolithic part.

7. An optical connector, comprising:
a first ferrule;
a second ferrule;
an optical waveguide extending from the second ferrule;
a guide that guides the optical waveguide, and includes an upper part, an inclined part, and a bent part connecting the upper part and the inclined part; and
a clip that pinches the first ferrule and the second ferrule together,
wherein the guide is attached to the clip.
