Description

Technical Field

[0001] The utility model relates to the technical field of backup wire clamps, in particular to a safety backup wire clamp. Background Art

[0002] Cable securing and protection are crucial in fields such as power, communications, and data transmission. Traditional cable securing methods, such as tape, cable ties, or cable clamps, often suffer from issues such as insecure fixation, loosening, and difficulty adapting to cable movement. These issues are particularly acute when subjected to external forces or environmental vibrations. Therefore, the market urgently needs a secure backup cable clamp that can effectively secure cables while also accommodating cable movement within a certain range.

[0003] Existing backup cable clamp designs are often complex and difficult to install. Their clamping effectiveness is unstable when cables are displaced, which can easily cause cables to loosen or even fall off, posing a risk to the stable operation of power and communication systems. Furthermore, some cable clamps can damage cables during use, affecting their transmission performance and service life. Utility Model Content

[0032] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figure 1 As shown in the figure, in actual use, the backup clamp is used in conjunction with the tension clamp 19, and the cable 20 passes through the tension clamp 19 and the backup clamp at the same time. Figure 2-Figure 4 As shown, the backup wire clamp includes a housing 10 having a cavity 11, and first through holes 13 for the cable 20 to pass through are provided at both ends of the housing 10; a movable clamp 15 is movably arranged in the cavity 11, and second through holes 14 are provided at both ends of the movable clamp 15 that coincide with the first through holes 13;

[0035] An inclined wall 12 is provided in the cavity 11, and the inclined wall 12 extends toward the first through hole 13. An outer surface of the movable clamp 15 is provided with a beveled edge that cooperates with the inclined wall 12. One end of the movable clamp 15 clamps the cable 20. When the cable 20 is displaced under the action of external force, the movable clamp 15 can move with the cable 20 in the cavity 11, and when the movable clamp 15 moves to one side, it clamps the cable 20 under the action of the inclined wall 12.

[0036] Specifically, the movable fixture 15 includes a first movable body 16 and a second movable body 17 . The first movable body 16 and one end of the second movable body 17 are connected to form the second through hole 14 . The cavity 11 further includes a movable area 21 for the movable body to move.

[0037] The movable clamp 15 can clamp the cable 20 leftward or rightward or up and down, that is, the inclined wall 12 of the cavity 11 can be provided on both the upper and lower sides or on both the left and right sides.

[0038] There are two inclined walls 12 and they are relatively arranged on the top wall, bottom wall or left wall and right wall of the cavity 11. The two inclined walls 12 are mirror-symmetrical to each other, and both of them extend obliquely toward the first through hole 13 on the same side.

[0039] Specifically, a plurality of arc-shaped protrusions 18 are provided in the second through hole 14 to increase the friction between the movable clamp 15 and the cable 20. The slope of the inclined wall 12 is the same as that of the hypotenuse. The first movable body 16 and the second movable body 17 are an integrated structure.

[0040] This embodiment provides a manufacturing process for a safety backup wire clamp, which includes a housing 10 having a cavity 11. Both ends of the housing 10 are provided with first through holes 13 for passing cables 20. The housing 10 is made of high-strength copper alloy material, and the diameter of the first through hole 13 is 10 mm.

[0041] A movable fixture 15 is fabricated. The movable fixture 15 includes a first movable body 16 and a second movable body 17. The first movable body 16 and the second movable body 17 are connected at one end to form a second through hole 14. Both the first movable body 16 and the second movable body 17 are made of highly elastic rubber material. The diameter of the second through hole 14 is 8 mm.

[0042] An inclined wall 12 is provided within the cavity 11, extending toward the first through hole 13. The inclined wall 12 is inclined at a 12-degree angle and is positioned relative to the top and bottom walls of the housing 10. A beveled edge is provided on the outer surface of the movable clamp 15 to mate with the inclined wall 12. The slope of the beveled edge is the same as that of the inclined wall 12, both at 12 degrees. A plurality of arcuate protrusions 18 are provided within the second through hole 14 to increase friction between the movable clamp 15 and the cable 20. The arcuate protrusions 18 have a diameter of 2 mm and are spaced 5 mm apart.

[0043] The movable clamp 15 is placed in the cavity 11 so that its two ends coincide with the first through hole 13. The cable 20 is displaced under the action of an external force, and the movement of the movable clamp 15 in the cavity 11 is observed. The results show that the movable clamp 15 can move with the movement of the cable 20, and when the movable clamp 15 moves to one side, it gradually clamps the cable 20 under the action of the inclined wall 12, thereby increasing the contact area with the cable 20 and increasing the resistance of the wire clamp. Through the above steps, the production and testing of the safety backup wire clamp are completed. The results show that the safety backup wire clamp can effectively fix the cable 20 and prevent the cable 20 from loosening and falling off, thereby improving the safety of the power system. At the same time, due to its simple structure, low manufacturing and installation costs, it has good practical value.

[0044] Example 2

[0045] like Figure 5-Figure 6 As shown, the difference from Example 1 is that the number of the inclined walls 12 is four and they are relatively arranged on the top wall, bottom wall or left wall and right wall of the cavity 11, wherein the inclined walls 12 are arranged opposite to each other in pairs, and the two inclined walls 12 arranged on the same wall surface are mirror images of each other, and the two inclined walls 12 arranged opposite to each other extend toward the first through hole 13 on the same side.

[0046] That is, no matter whether the cable 20 moves leftward or rightward, the movable clamp 15 can move along with the cable 20 and gradually clamp the cable 20 .

[0047] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
