Description

A special fastener for signal cable termination Technical Field

[0001] This utility model relates to the field of box termination manufacturing technology; specifically, this utility model relates to a special fixing device for signal cable termination. Background Technology

[0002] In traditional signal cable termination construction, to prevent the cable from falling out of the protective conduit, wire is used to bind the bottom of the cable termination and then press the wire down at the connection between the protective conduit and the auxiliary protective conduit. However, using wire to fix the termination has two drawbacks: First, binding the wire too tightly can damage the cable core, while binding it too loosely can easily cause the cable to fall out of the protective conduit; second, wire is prone to metal fatigue, easily twisted and broken during binding, and it will rust, losing its function of fixing the cable after corrosion. Summary of the Invention

[0003] In view of this, the present invention provides a special fixing device for signal cable termination, thereby solving or at least alleviating the above-mentioned problems existing in the prior art.

[0004] To achieve the aforementioned objective, this utility model provides a special fixing device for signal cable termination, comprising an annular fixing part and a strip fixing part. The annular fixing part can be fixed to the outside of the signal cable, one end of the strip fixing part is connected to the annular fixing part, and the other end of the strip fixing part is pressed between the connection between the protective tube and the auxiliary protective tube.

[0006] In the signal cable termination fastener described above, optionally, the front end of the strip-shaped fastening part is bent and fitted onto the annular fastening part.

[0007] In the signal cable termination fastener described above, optionally, the strip-shaped fixing part has a straight section on the rear side of the annular part, and the straight section is covered with an auxiliary clamp that presses it against the signal cable, and the outer diameter of the auxiliary clamp is adapted to the inner diameter of the protective tube.

[0008] In the signal cable termination fastener described above, optionally, the rear end of the strip-shaped fixing part is bent and attached between the connection end of the pre-protective tube and the auxiliary protective tube, and the outer side of the rear end bend of the strip-shaped fixing part is covered with a pressure ring that is pressed against the bend, and the pressure ring is provided with bolt holes that cooperate with the protective tube.

[0009] The advantages of this utility model compared to the prior art are:

[0010] 1. In this application, the front end of the strip-shaped fixing part is bent and pressed between the ring-shaped fixing part and the signal cable, and the rear end of the strip-shaped fixing part is bent and pressed between the protective tube and the auxiliary protective tube, which serves to fix the signal cable and solves the problems of easy twisting and breakage of the cable core and easy rusting and breakage of the iron wire when using iron wire to bind the cable.

[0011] 2. This application has a simple structure, is easy to operate, saves time and effort, and has low manufacturing cost. It can be widely used in signal cable termination manufacturing, improves construction efficiency, and avoids subsequent problems. Attached Figure Description

[0017] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] As shown in Figures 1 to 4, a typical embodiment of this utility model provides a special fixing device for signal cable termination, including an annular fixing part 1 and a strip fixing part 2. The annular fixing part 1 can be fixed to the outside of the signal cable. One end of the strip fixing part 2 is connected to the annular fixing part 1, and the other end of the strip fixing part 2 is pressed between the connection between the protective tube 6 and the auxiliary protective tube 7.

[0019] The front end of the strip-shaped fixing part 2 is connected to the ring-shaped fixing part 1, and its rear end is pressed between the protective tube 6 and the auxiliary protective tube 7, so that the strip-shaped fixing part 2 can fix the ring-shaped fixing part 1. At this time, the signal cable is fixed in conjunction with the ring-shaped fixing part 1 to achieve the effect of fixing the signal cable on the protective tube 6.

[0020] In a relatively specific embodiment, the annular fixing part 1 is a stainless steel clamp, and the strip fixing part 2 is a stainless steel clip. Specifically, the stainless steel clamp is 8mm wide and 40mm in diameter, and the stainless steel fixing clip is 8mm wide and not less than 150mm in length.

[0021] In this design, the front end of the strip-shaped fixing part 2 is bent and fitted onto the annular fixing part 1, and the rear end of the strip-shaped fixing part 2 is bent and attached to the connection end between the pre-protective tube 6 and the auxiliary protective tube 7. This design allows the strip-shaped fixing part 2 to be flexibly bent on-site according to actual conditions, and the operation is simple and easy to implement.

[0022] A straight section 3 is provided on the rear side of the annular portion 2 of the strip-shaped fixing part 2. An auxiliary clamp 4 is wrapped around the straight section 3 to press it against the signal cable, and the outer diameter of the auxiliary clamp 4 matches the inner diameter of the protective tube 6. By providing the straight section 3 and the auxiliary clamp 4, the auxiliary clamp 4 can press the bent portion at the front end of the strip-shaped fixing part 2 against the signal cable, thus shaping the front end of the strip-shaped fixing part 2. Furthermore, after the protective tube 6 is installed, it is pressed against the outside of the auxiliary clamp 4, further stabilizing the auxiliary clamp 4 and improving the stability of the strip-shaped fixing part 2, ensuring that it can stably fix the annular fixing part 1.

[0023] The rear bend of the strip-shaped fixing part 2 is covered by a pressure ring 5 that is pressed against the bend. The pressure ring 5 has bolt holes that mate with the protective tube 6. By setting the pressure ring 5, when the strip-shaped fixing part 2 is bent, the connecting bolts of the protective tube 6 and the auxiliary protective tube 7 are passed through the threaded holes on the pressure ring 5 to press the pressure ring 5 against the auxiliary protective tube 7. The pressure ring 5 can shape the rear end of the strip-shaped fixing part 2 by pressing it against the auxiliary protective tube 7, so that the shaped state of the strip-shaped fixing part 2 can completely match the auxiliary protective tube 7. Moreover, after the strip-shaped fixing part 2 is fixed by the protective tube 6 and the auxiliary protective tube 7, it can effectively maintain the position of the annular fixing part 1, thereby improving its anti-detachment effect on the signal cable.

[0024] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
