Abstract

The optical adapter includes a first housing 3, a second housing 5, and a sleeve 7. The first housing 3 includes a connector holding part 31, a first holder portion 33, an alignment part 35, and coupling portions 36. The first holder portion 33 is integrally formed with the connector holding part 31. The alignment part 35 includes an alignment part main body 351, a second holder portion 352 integrally formed with the alignment part main body 351, and a plurality of guide portions 352, 354, and 355, integrally formed with the alignment part main body 351. Protrusion-shaped coupling portions 36 for coupling the connector holding part 31 and the alignment part 35 are integrally formed with one of the connector holding part 31 and the alignment part main body 35.

Claims6

Dependent claims

An optical adapter comprising:

a first housing for receiving a first optical connector which is connectable to said first housing;
a second housing for receiving a second optical connector which is connectable to said second housing, said first housing being fitted to said second housing;
and
a sleeve that causes an end surface of an optical connection portion of the first optical connector and an end surface of an optical connection portion of the second optical connector to be brought into abutment with each other, when the first optical connector and the second optical connector are received by and connected to said first housing and said second housing, respectively,
wherein said first housing includes:
a connector holding part including a connector holding part main body for holding the first optical connector, and a first holder portion integrally formed with said connector holding part main body, for holding one end portion of said sleeve;
and
an alignment part including an alignment part main body which can be mounted on said connector holding part main body, a second holder portion integrally formed with said alignment part main body, for holding another end portion of said sleeve, and a plurality of protrusion-shaped guide portions integrally formed with said alignment part main body, for relatively guiding said second housing when said first housing and said second housing are fitted to each other,
wherein protrusion-shaped coupling portions for coupling said connector holding part main body and said alignment part main body to each other are integrally formed on one of said connector holding part main body and said alignment part main body, and
wherein at least one of the plurality of guide portions is different in size from another one of the plurality of guide portions.
