Abstract

Disclosed is an optical-connector fixing member including: an upper plate part for pressing, toward a receptacle provided on a substrate, a ferrule that holds an end section of an optical fiber; and a pair of engagement side plate parts formed so as to extend from the upper plate part toward the substrate, each engagement side plate part having a connector-side engagement section that engages with a receptacle-side engagement section formed on a side surface of the receptacle. An engaged state in which the connector-side engagement section is engaged with the receptacle-side engagement section is releasable by inserting an end section of a tool into a gap between each engagement side plate part and a member that is arranged between the pair of engagement side plate parts, and spreading each engagement side plate part outward.

Claims

1. An optical-connector fixing member comprising:

an upper plate part for pressing, toward a receptacle provided on a substrate, a ferrule that holds an end section of an optical fiber; and

a pair of engagement side plate parts formed so as to extend from said upper plate part toward said substrate, each said engagement side plate part having a connector-side engagement section that engages with a receptacle-side engagement section formed on a side surface of said receptacle,

wherein an engaged state in which said connector-side engagement section is engaged with said receptacle-side engagement section is releasable by inserting an end section of a tool into a gap between each said engagement side plate part and a member that is arranged between said pair of engagement side plate parts, and spreading each said engagement side plate part outward.

2. The optical-connector fixing member according to claim 1, wherein said gap becomes narrower toward said substrate.

3. An optical connector comprising:

a ferrule that holds an end section of an optical fiber; and

a fixing member that fixes said ferrule in a state where said ferrule is arranged between said fixing member and a receptacle provided on a substrate, wherein;

said fixing member includes

an upper plate part for pressing said ferrule toward said receptacle, and

a pair of engagement side plate parts formed so as to extend from said upper plate part toward said substrate, each said engagement side plate part having a connector-side engagement section that engages with a receptacle-side engagement section formed on a side surface of said receptacle; and

an engaged state in which said connector-side engagement section is engaged with said receptacle-side engagement section is releasable by inserting an end section of a tool into a gap between each said engagement side plate part and a member that is arranged between said pair of engagement side plate parts, and spreading each said engagement side plate part outward.

4. An optical connector device comprising:

a receptacle to be attached onto a substrate; and

an optical connector that is attachable to and detachable from said receptacle, wherein;

said optical connector includes

a ferrule that holds an end section of an optical fiber, and

a fixing member that fixes said ferrule in a state where said ferrule is arranged between said fixing member and said receptacle provided on a substrate;

said fixing member includes

an upper plate part for pressing said ferrule toward said receptacle, and

a pair of engagement side plate parts formed so as to extend from said upper plate part toward said substrate, each said engagement side plate part having a connector-side engagement section that engages with a receptacle-side engagement section formed on a side surface of said receptacle; and

an engaged state in which said connector-side engagement section is engaged with said receptacle-side engagement section is releasable by inserting an end section of a tool into a gap between each said engagement side plate part and a member that is arranged between said pair of engagement side plate parts, and spreading each said engagement side plate part outward.
