Abstract

An optical connector socket includes: a body having an insertion section in which a socket-side optical element is arranged and into which an optical connector plug is inserted; a cover, covered on the body, having an opening communicated with the insertion section; a shutter, openably/closably attached to the cover, for closing the opening; and a herical spring for elastically urging the shutter in a constant-closing direction. The opening is larger than an outside dimension of the optical connector plug inserted into the cover and smaller than that of the shutter. Therefore, there is no light leakage and dust intrusion, the socket can be attached to a device or a wall so as to direct an opening toward a front face without a cap, and an inspection in a state where the socket is assembled in an electronic device can be performed without attaching/detaching the cap to/from the socket.

Claims3

Dependent claims

An optical connector socket comprising:

a body having a socket-side optical device installed therein and an insertion section to which a connected optical connector plug is inserted,
a cover that is covered on the body and having a front frame section, the front frame section having an opening section communicating with the insertion section;
a shutter openably and closably attached to the cover for closing the opening section and a helical spring that always elastically urges the shutter in a closing direction, against a back surface of the frame section;
wherein the opening section is set to have an outside dimension greater than the outside dimension of the optical connector plug inserted into the cover and smaller than the outside dimension of the shutter;
wherein the helical spring urges the shutter so as to bring all the periphery of the shutter into abutment with a back surface of the first frame section;
wherein a pair of guide projections is provided at the inside of the insertion section of the body for guiding the inserted optical connector plug toward the socket-side optical device, and
wherein a distance between the guide projections becomes narrower toward the backside of the insertion section.
