摘要： This optical connector with a shutter is for blocking emitted light from the connected optical connector, such as an optical connector adaptor, provided in a connector hole of a connector housing by using a shutter. In this optical connector with a shutter, the shutter unit is assembled in the center part of the connector housing, and the emitted light in the connector hole from the connected optical connector is blocked by shutter pieces of the shutter unit. Furthermore, an electromagnetic shielding capacity can be obtained without enlarging the optical connector by making the shutter unit from electrically conducting members.

摘要： The present invention relates to a technique for intercepting light which is emitted from a connection reception side optical connector which is housed inside a connector hole of a connector housing of a device such as an optical connector adapter or the like using a shutter, and more particularly relates to a development of this technology which makes it possible to arrange the shutter without exerting the negative effect of increasing the size of the connector housing. With the present invention such light interception is implemented, without increasing the size of the connector housing 14, by providing a structure in which a shutter unit is fitted within a connector hole 14a of a connector housing 14, with this shutter unit comprising two shutter leaves 53A and 53B for light interception supported upon shafts in a main section 51 of the assembly. Furthermore it is possible to guarantee the dust interception characteristic of the connector hole, since the plurality of shutter leaves 53A and 53B mutually overlap with one another so as to close off the connector hole 14a when they are in their light interception positions.

摘要： An optical connector includes a connector housing; an optical ferrule that is housed in the connector housing; a coil spring that is housed in the connector housing and impresses the optical ferrule in a forward direction; and a spring pressing portion that is attached to an rear end of the connector housing, has an optical fiber inserting through-hole and a spring reception portion, and receives a reaction force of the coil spring. The spring pressing portion is divided into two half bodies. Since the spring pressing portion is divided into two parts, at the time of assembly of the optical connector, the optical ferrule is attached to the optical fibers and is terminated, and then the optical fibers can be covered with the spring pressing portion. At the time of the terminating operation, since there is no spring pressing portion that causes interference in the operation, it is easy to perform the terminating operation of the optical ferrule.
