Description

  The present invention relates to an optical fiber with a connector for pulling the optical fiber cord with a connector when an optical fiber cord with a connector provided with an optical connector at an end of the optical fiber cord is laid and wired in, for example, an indoor pipe. The present invention relates to a cord pulling jig and method.

  When laying and wiring an optical fiber cord, a towline, that is, a rope or wire, is laid in advance on the route or pipe for wiring, and the towline and the optical fiber cord to be laid are connected to each other. An optical fiber cord is laid by winding the wire.

  In recent years, it has also been proposed to install an optical fiber cord with an optical connector attached to the tip. There exists a thing like patent document 1 as an optical fiber pulling device.

  In the conventional traction tool used to connect the tow rope and the optical fiber cord, since the locking piece is used for gripping the SC (Single Fiber Coupling) connector, the number of members is large. It becomes a long and large object, and it becomes difficult to pull by being caught at the uneven portion or the bent portion of the pipe, and there is a possibility that the optical connector portion and the optical fiber are damaged. In addition, the number of parts constituting the traction jig is large, and an expensive material and an expensive processing method are required, and there is a problem that the cost increases.

  Furthermore, the method of pulling the optical fiber cord by placing a pulling jig on the protrusion of the optical connector housing increases the load on the protrusion, and the optical connector housing may be damaged. There was a problem of lack of time stability.
