BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a connector fitting pin according to the present invention will be described below in detail with reference to FIGS. 1 to 5. 1 is an exploded perspective view of an optical fiber connector including a connector fitting pin according to the present invention, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a plan view showing a connection state of FIG. 2, and FIG. 4 is a connector of FIG. FIG. 5 is a perspective view showing a modification of the fitting pin, and FIG. 5 is a perspective view showing still another modification of the connector fitting pin in FIG.

As shown in FIG. 1, an optical fiber connector 1
Is composed of a pair of optical fiber connectors 1a and 1b and a connector pin 10 having a substantially U shape. The connector fitting pin 10 is provided in a pair of guide holes 4 provided in the optical fiber connector 1 in order to position the pair of optical fiber connectors 1 for connecting the end faces of the core wires 3 of the multi-core optical fiber tape 2 to each other. It is composed of a pair of fitting pins 5 and 5 to be fitted and a connecting member 6 integrally connected to one end of the pair of fitting pins 5 and 5.

Further, since the connecting member 6 is provided with the escape portion 7, the connecting member 6 can be brought into contact with the rear end face of the optical fiber connector 1b without interfering with the boot 8 at the time of connection. Therefore, since the connector fitting pin 10 is stably held in the optical fiber connector 1b, the reliability of the optical fiber connector 1 can be improved. Further, since the connector fitting pin 10 can be applied to the conventional optical fiber connectors 1a and 1b, it can be expected economically.

The present invention is not limited to the above-described embodiment, but can be embodied in other modes by making appropriate changes. For example, the relief portion 7 shown in FIG. 1 has a shape matching the shape of the boot 8, but like the connector fitting pin 20 shown in FIG. 4, it has an arc-shaped relief portion that also serves as the connecting member 26. Even if it is 27, it does not matter. Also, like the connector fitting pin 30 shown in FIG. 5, a pair of fitting pins 35 may be fitted and adhered to the guide hole 34 of the connecting member 36 formed of synthetic resin or the like having the escape portion 37. It doesn't matter. In this case, the pitch of the fitting pins 35 can be set more accurately.
