なり。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device-side optical connector consisting of a box-shaped front housing with an opening at the front and an optical connector body attached to the housing via a back wiring board. , relates to a plug-in optical connector that is mounted on an electronic circuit package and is configured with a mating optical connector that is inserted into and removed from the front housing. [Prior Art] Conventional plug-in optical connectors, such as the 1988 Electronic Communication The "Plug-in Optical Connector" (preliminary to this conference, see pages 3-349 and 350), which was announced at the national conference of the communications division of the academic society, is a plug-in optical connector that connects the front and back of the back wiring board of optical communication equipment, etc.
a device-side optical connector having a front housing with an open front and a rear housing equipped with a plug;
It consists of a mating optical connector that is inserted into and removed from the front housing.

には不必要であるなんらかの安全対策を施さねばならな
いので、装置自体の取扱いを難しくする問題があった。In the above conventional example, if the optical connector on the other side is not mated, the laser beam emitted from the optical connector on the device side to the outside reaches the front of the device without any obstruction, so the work is done in front of the device. This poses a safety problem because there is a risk that the laser beam may enter the eyes of the worker who is performing the process. For this reason, it is necessary to take some kind of safety measures that are unnecessary for a device equipped with only an electrical connector, which poses a problem that makes the device itself difficult to handle.
又、上記の場合、元コネクタのプラグはオープン状態に
あるので、該プラグにとみ及び塵埃などが付着しやすく
なるから、光損失などの特性劣化を生ずる恐れがある。Further, in the above case, since the plug of the original connector is in an open state, dirt and dust are likely to adhere to the plug, which may cause deterioration of characteristics such as optical loss.
このため、プラグの清掃作業を実施する必要があるので
、上記と同様に装置の取扱いを難しくする問題がありた
。For this reason, it is necessary to perform a cleaning operation on the plug, which poses the problem of making the device difficult to handle, similar to the above.

防止できる。When the device-side and other-party connectors are not mated, the pair of shield plates attached to the opening of the front housing of the device-side optical connector are closed by an elastic force to close the opening. Therefore, foreign matter can be prevented from entering the front housing.
