なければならないという煩わしさがあった。(Issues) However, because conventional optical connectors have the above configuration, when the two connector blocks are disconnected, it is not known which connector block the positioning pins will remain in, and if the positioning pins will remain in one connector block. Even if the pin is inserted, the insertion state may be incomplete, or even the pin may fall out without remaining in either connector block, and it is troublesome to have to check the state of the positioning pins each time they are reconnected. There was a time.

磁石を固定したことを特徴とするものである。In order to solve the problems of the prior art as described above, the present invention provides an optical connector that has two connector blocks whose end faces are butted against each other, and a pair of positioning pins that are inserted across the pin holes of both connector blocks. The positioning pin is made of a magnetic material, and a magnet is fixed to the back of one of the pin holes that face each other when the two connector blocks are butted together.

In the figure, IA-IB is a connector block, 2a/2
b is a positioning pin. Connector block LA/IB
are attached to the ends of the multi-core optical fibers 3A and 3B to be connected, respectively, and the end faces of the optical fibers 4 are exposed at the end faces arranged in a predetermined pinch. Further, a pair of pin holes 5a and 5b are formed on both sides of the connector blocks IA and IB, respectively. Pin holes 5a and 5b
The inner diameters of the locating pins 2a and 2a are all the same size.
2b has a uniform outer diameter so that the iHJ fits into the pin holes 5a and 5b. Further, the positioning pins 2a and 2b are made of a magnetic material such as steel.

なる。In the optical connector in Figure 1, one connector block IA
The connector block IB has a structure in which a permanent magnet 6 such as a ferrite magnet is fixed in the deep part of the pin holes 5a and 5b, and the other connector block IB has a structure in which the rear ends of the pin holes 5a and 5b are open to the outside. It becomes. Therefore, if you try to pull out the positioning pins 2a and 2b after inserting them into the pin holes 5a and 5b to which the magnet 6 is fixed, the positioning pins 2
Since a and 2b are attracted by the magnet 6, it is difficult to remove them from their pin holes (for this reason, both connector blocks IA and IB were inserted and connected so that the positioning pins 2a and 2b spanned both. Afterwards, when the connection is released, the positioning pins 2a and 2b will always remain in the pin hole to which the magnet 6 is fixed, that is, on the one connector block IA side.

のようにしても図−１と同様の作用効果が得られる。Next, in the optical connector of FIG. 2, one connector block IA has a magnet 6 fixed to the inner part of the pin hole 5a on one side.
The inner part of the pin hole 5b on the opposite side is opened to the outside, and the other connector block IB has a structure in which the inner part of the pin hole 5a on one side is opened to the outside, and the inner part of the pin hole 5b on the opposite side is opened to the outside. It has a structure in which a magnet 6 is fixed in the inner part of the body. Even in this case, the same effect as shown in FIG. 1 can be obtained.

The positioning pin will remain in the pin hole on the side where the magnet is located due to the attractive force of the magnet. Therefore, both connector blocks can always be reconnected in the same state, which has the advantage of improving work efficiency.
