Abstract
In an optical connector, a connector main body includes an integrally formed plug frame. The plug frame has a connecting portion accommodation portion accommodating a ferrule, a mechanical splice, and a spring biasing the mechanical splice toward the ferrule, and a guide portion guiding the optical fiber extending from an optical cable. The connecting portion accommodation portion and the guide portion are partitioned via a partition wall having a cylindrical protrusion protruding into the connecting portion accommodation portion. The guide portion has a curved face extending in a conical shape from the partition wall.

An optical connector comprising:
- a connector main body;
- an optical fiber connecting portion incorporated in the connector main body and having a built-in fiber connected to an optical fiber of an optical cable;
- and
- an outer sheath fixing portion fixing an outer sheath of the optical cable,
- wherein the connector main body includes an integrally formed plug frame,
- wherein the optical fiber connecting portion includes:
- a ferrule holding the built-in fiber;
- and
- a mechanical splice connecting the built-in fiber and the optical fiber to each other,
- wherein the plug frame includes:
- a connecting portion accommodation portion accommodating the ferrule, the mechanical splice, and a spring biasing the mechanical splice;
- and
