Abstract

An optical connector receptacle of the invention includes: a receptacle housing holding a ferrule; a flange protruding from an external surface of the receptacle housing; an elastic deformation portion extending from the flange along the external surface of the receptacle housing; and a locking protruding portion protruding from the elastic deformation portion to the opposite side of the external surface of the receptacle housing. The optical connector receptacle is attachable to an attachment wall by sandwiching a peripheral edge of an attachment hole of the attachment wall between the flange and the locking protruding portion. A state where the locking protruding portion is locked by the peripheral edge of the attachment hole of the attachment wall is releasable as a result of elastically deforming the elastic deformation portion to be directed to the external surface of the receptacle housing.

Claims

1. An optical connector receptacle comprising:

a ferrule to which an optical fiber is inserted and fixed;

a receptacle housing holding the ferrule;

a flange protruding from an external surface of the receptacle housing;

an elastic deformation portion extending from the flange along the external surface of the receptacle housing; and

a locking protruding portion protruding from the elastic deformation portion to the opposite side of the external surface of the receptacle housing, wherein

the flange, the elastic deformation portion, and the locking protruding portion are formed integrally with the receptacle housing,

the optical connector receptacle is attachable to an attachment wall by sandwiching a peripheral edge of an attachment hole of the attachment wall between the flange and the locking protruding portion, and

a state where the locking protruding portion is locked by the peripheral edge of the attachment hole of the attachment wall is releasable as a result of elastically deforming the elastic deformation portion to be directed to the external surface of the receptacle housing.

2. The optical connector receptacle according to claim 1, wherein

the elastic deformation portion extends from the flange so as to be formed in a cantilever shape.

3. The optical connector receptacle according to claim 1, wherein

the locking protruding portion is formed at a connector insertion portion side into which another connector is inserted with respect to the flange.

4. The optical connector receptacle according to claim 1, wherein

the locking protruding portion has a recess into which a protrusion is to be inserted, and the protrusion protrudes from a pressing face of a jig pressing the locking protruding portion.

5. The optical connector receptacle according to claim 1, wherein

the optical fiber includes a portion having a tape-shaped multi-core.

6. The optical connector receptacle according to claim 1, wherein

the receptacle housing comprises:

a spring pressing against the ferrule; and

an internal mechanism container accommodating a spring pusher receiving the spring.

7. The optical connector receptacle according to claim 6, wherein

the receptacle housing has an opening portion at an end of the internal mechanism container opposite to a connector insertion portion into which another connector is inserted,

the spring pusher comprises:

a substrate portion blocking the opening portion;

a bend portion bending from an end of the substrate portion along an inner surface of the internal mechanism container; and

a locking claw protruding from the bend portion, and

the receptacle housing comprises an engagement portion engaging with the locking claw at a side surface of the internal mechanism container.

8. The optical connector receptacle according to claim 6, wherein

the spring pusher has a through hole, through which the optical fiber passes, and has a spring applied part receiving the spring at a peripheral edge of the through hole.

9. A receptacle housing comprising:

a ferrule holder holding a ferrule to which an optical fiber is inserted and fixed;

a flange protruding from an external surface of the receptacle housing;

an elastic deformation portion extending from the flange along the external surface; and

the flange, the elastic deformation portion, and the locking protruding portion are formed integrally with the ferrule holder,

the receptacle housing is attachable to an attachment wall by sandwiching a peripheral edge of an attachment hole of the attachment wall between the flange and the locking protruding portion, and

a state where the locking protruding portion is locked by the peripheral edge of the attachment hole of the attachment wall is releasable as a result of elastically deforming the elastic deformation portion to be directed to the external surface.

10. The receptacle housing according to claim 9, wherein

the elastic deformation portion extends from the flange so as to be formed in a cantilever shape.

11. The receptacle housing according to claim 9, wherein

the locking protruding portion is formed at a connector insertion portion side into which another connector is inserted with respect to the flange.
