The optical connector that is attached to the end of the optical fiber and used for switching connection of the optical transmission line is butt-connected with the optical connector of the other side, while pressing in the butt direction with a spring etc. to maintain the butt state of both optical connectors, It is known that one of the optical connectors is mechanically moved in parallel along the abutting end faces to switch the optical transmission line, and for example, the one disclosed in Japanese Patent Laid-Open No. 63-231308 is known.

伝送特性に悪影響を生ずるという問題があった。By the way, in such an optical connector for mechanically switching the optical transmission line, a mechanical structure using a solenoid, for example, is used as a driving means for moving the optical connector in parallel with the switching. Since it has to be arranged around the optical switch, there is a problem that the switching device used for switching the optical connector becomes large. In addition, since the optical connector moves parallel with the abutting end faces abutting when switching, the end faces of the optical fibers exposed at the abutting end faces rub against each other, resulting in scratches on the fiber end faces and optical signal transmission loss. However, there is a problem in that the transmission characteristics of the optical signal are adversely affected, such as the increase in noise.

供することを目的とする。Further, since the abutting state of the optical connectors is held by utilizing the pressing force of the spring, the pressing force changes depending on the mounting state of the spring, the connection loss changes, and the stability of the abutting state changes. There was also the problem of doing it.
The present invention has been made in view of the above points, and it is possible to downsize the switching device, without causing scratches on the end face of the optical fiber at the time of switching, and to keep the abutted state of the abutted optical connectors constant. An object is to provide an optical connector that can be held.

態で相対移動する。First, in the state shown in FIG. 3, the iron core 6a
The coil 6d of each straight pin 6 is energized so that the end of the coil becomes the S pole. Then, since the leg 5a of the U-shaped pin 5 facing each iron core 6a also has the S pole, the leg 5a and the iron core 6
A repulsive force acts between the optical connectors 1 and 1 and the optical connectors 1 and 1 start relative movement, and at the intermediate position, the tips of the iron cores 6a ride on the front surface of the ferrule 1a, and the state shown in FIG. 4 is obtained.

The tip of the iron core 6a is changed to the N pole, and the optical connectors 1 and 1 relatively move in the opposite direction by the operation opposite to the above, and the optical transmission path is switched to the original connection state. At this time, even if the coil 6d is de-energized, the optical connectors 1 and 1 are maintained in the butt connection state due to the attractive force applied to the iron core 6a from the leg 5a of the U-shaped pin 5.

の小型化が可能である。As is apparent from the above description, according to the optical connector of the present invention, the positioning pin inserted into the pin hole of at least one optical connector is the permanent magnet, and the pin hole of at least the other optical connector. Since the positioning pin inserted in the is an electromagnet, by changing the energizing direction to the positioning pin of the electromagnet, it is possible to switch the optical connectors butt-connected to each other, unlike the conventional optical connector,
It is possible to downsize the switching device without requiring a separate driving means for switching driving.

Since the transmission characteristics of the optical signal are not deteriorated and the abutting state of the optical connectors is held by the magnetic force, the abutting state is kept constant.
