Abstract

A novel optical cable junction box relates to the technical field of communication equipment and comprises a left box (1), a middle box (2) and a right box (3), wherein the left box (1) and the right box (3) are connected with the middle box (2) via threads; internal threads are formed on the right side of the left box (1); external threads are formed at the left end of the middle box (2) and internal threads are formed at the right end of the middle box (2); and external threads are formed at the left end of the right box (3). By adopting the scheme, the present optical cable junction box is designed into a retractable structure: the junction box can be lengthened when a connecting notch is longer or the number of the cable cores is large while the junction box can be shortened when the connecting notch is shorter or the cable cores are fewer, so that the work efficiency is improved, and the loss is reduced.

Description

A kind of novel cable junction box

Technical field:

The utility model relates to the communication facilities technical field, is specifically related to a kind of novel cable junction box.

Background technology:

Development of Communication Technique, optical cable is big because of its transmission capacity, speed is fast, distorted signals is little and be widely used, but the limited length of optical cable, in work progress, must carry out two optical fiber between the optical cable connects, perhaps work as optical cable and arrive certain node, when needing different directions branch family to use, also need the optical fiber between the optical cable to connect, so in communication engineering, cable junction box is indispensable equipment, but the big or small length of terminal box in the market is fixed, when running into the optical cable that connects the long or big core number of breach, the cable junction box of fixed size can't use.

The utility model content:

The purpose of this utility model provides a kind of novel cable junction box, it is that existing cable junction box is set to telescopic, run into the terminal box that to extend when growing the optical cable that connects breach or big core number, run into and shortly can shorten terminal box when connecting the less optical cable of breach or core number, improve work efficiency, reduced loss.

In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises left box 1, middle box 2 and right box 3, and left box 1 is connected with middle box 2 by screw thread with right box 3.

The right side of described left box 1 is provided with internal thread.

The left end of box 2 is provided with external thread in the middle of described, and right-hand member is provided with internal thread.

The left end of described right box 3 is provided with external thread.

The utlity model has following beneficial effect: it is that existing cable junction box is set to telescopic, run into the terminal box that to extend when growing the optical cable that connects breach or big core number, run into and shortly can shorten terminal box when connecting the less optical cable of breach or core number, improve work efficiency, reduced loss.

Description of drawings:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is the synoptic diagram of left box 1,

Fig. 3 is the synoptic diagram of middle box 2,

Fig. 4 is the synoptic diagram of right box 3.

Embodiment:

Referring to Fig. 1-4, it comprises left box 1, middle box 2 and right box 3, and left box 1 is connected with middle box 2 by screw thread with right box 3.

The right side of described left box 1 is provided with internal thread.

The left end of described right box 3 is provided with external thread.

During construction, the left end external thread of middle box 2 and the internal thread of left box 1 right-hand member can be connected, the right-hand member internal thread of middle box 2 and the external thread of right box 3 left ends are connected if run into when growing the optical cable that connects breach or big core number, form long terminal box, if run into short when connecting the less optical cable of breach or core number, the right-hand member internal thread of left box 1 and the external thread of right box 3 left ends can be connected, form less terminal box.

This embodiment is that existing cable junction box is set to telescopic, run into the terminal box that to extend when growing the optical cable that connects breach or big core number, run into and shortly can shorten terminal box when connecting the less optical cable of breach or core number, improved work efficiency, reduced loss.
