Description

Technical Field

[0001] The utility model relates to the technical field of elevator facilities, in particular to a flat cable clamp. Background Art

[0002] Elevator flat connecting wire, also known as flat cable, is a commonly used elevator power connection accessory. It is widely used in distribution cabinets, electrical equipment and elevators. During the installation process, the flat cable needs to be clamped and limited by a cable clamp to facilitate the sorting of the flat cables. The corners of the clips of traditional flat cable clamps are right-angle structures, resulting in sharp corners of the clips that are easy to scratch the surface of the cable, and the inner side of the clip is a flat structure. After long-term use, the surface of the flat cable is prone to deformation and slipping in the clamp. Therefore, it is necessary to design a new cable clamp structure to solve the above problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a flat cable clamp whose clamping piece is provided with a clamping arc surface. When clamping the cable, the clamping piece contacts the cable through the clamping arc surface to prevent the edges of the clamping piece from being too sharp and scratching the surface of the cable. The side walls of the clamping piece are provided with reinforcing ribs and form an accommodating groove. The deformed surface of the cable after long-term use can enter the accommodating groove, thereby limiting the cable to prevent the cable from slipping along the clamping piece.

[0004] A flat cable clamp comprises two clamps connected to each other by bolts, wherein the opposite sides of the two clamps are provided with reinforcing ribs protruding outwards, and a receiving groove is formed on the opposite sides of the two clamps, and the top and bottom of the clamps are provided with clamping arc surfaces.

[0005] Preferably, the top surfaces and bottom surfaces of the two clips extend horizontally in opposite directions.

[0006] Preferably, the accommodating grooves include two, and the two accommodating grooves extend along the length direction of the clip, and two mounting through holes are provided on the facing side walls of the two clips near the left and right sides, and the two mounting through holes are located between the two accommodating grooves.

[0007] Preferably, the side walls of the two clips facing each other are riveted with rivet nuts at the position of one of the mounting through holes, and the side walls of the clips are riveted with limiting frames at positions corresponding to the rivet nuts.

[0008] Preferably, a rivet nut is riveted on one side of one of the clips facing the other clip at the positions of the two mounting through holes, and a limiting frame is riveted on the side wall of one of the clips at the position corresponding to the rivet nut.

[0009] Preferably, the opening of the limiting frame is arranged outward along the length direction of the accommodating groove so that the rivet nut is accommodated in the limiting frame.

[0010] The beneficial effect of the utility model is that the flat cable clamp cooperates with the clamping piece and the reinforcing ribs so that the clamping piece is provided with a clamping arc surface. When clamping the cable, the clamping piece contacts the cable through the clamping arc surface to prevent the edges of the clamping piece from being too sharp and scratching the surface of the cable. The side walls of the clamping piece are provided with reinforcing ribs and form an accommodating groove. The deformed surface of the cable after long-term use can enter the accommodating groove, thereby limiting the cable to prevent the cable from slipping along the clamping piece.

[0017] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0018] like Figures 1 to 2 As shown, a flat cable clamp comprises two clips 1 connected to each other by bolts 8, and the opposite sides of the two clips 1 are provided with outwardly protruding reinforcing ribs 2, and a receiving groove 3 is formed on the opposite sides of the two clips 1, and the top and bottom of the clips 1 are provided with clamping arc surfaces 4.

[0019] The working principle of the flat cable clamp described in the utility model is achieved through mutual cooperation, such as Figure 1 and 2As shown, the staff connects and installs two clips 1 through bolts 8. The two clips 1 are arranged opposite to each other and clamp the flat cable 9. The clip 1 is provided with a clamping arc surface 4. Therefore, when clamping the cable 9, the clip 1 contacts the cable 9 through the clamping arc surface 4, thereby replacing the sharper corners of the clip 1 to contact the cable 9, so as to prevent the sharper corners of the clip 1 from scratching the surface of the cable 9. In addition, after the cable 9 has been used for a long time, the surface of the cable 9 is often pulled and easily deformed, and the deformed surface of the cable 9 will enter the accommodating groove 3, so that the cable 9 can be limited. Even if the surface of the cable 9 is deformed, it is not easy to slip along the side wall of the clip 1, and the reinforcing ribs 2 on the clip 1 can improve the compressive strength of the clip 1, so that the clip 1 is not easy to bend and deform. Compared with the traditional cable clamp, the clip 1 of the flat cable clamp contacts the cable 9 through the clamping arc surface 4 to avoid scratching the surface of the cable 9, and the side wall of the clip 1 is provided with reinforcing ribs 2 and forms an accommodating groove 3. The deformed surface of the cable 9 after long-term use can enter the accommodating groove 3, thereby limiting the cable 9 to prevent the cable 9 from slipping along the clip 1.

[0020] Specifically, the cross-section of the clip 1 is a U-shaped structure, and the top surfaces and bottom surfaces of the two clips 1 extend horizontally in opposite directions, wherein the accommodating grooves 3 include two, and the two accommodating grooves 3 extend along the length direction of the clip 1, and the two facing side walls of the two clips 1 are provided with two mounting through holes 5 near the left and right sides, and the two mounting through holes 5 are between the two accommodating grooves 3, and further, the facing side walls of the two clips 1 are riveted with a rivet nut 6 at the position of one of the mounting through holes 5, and the side walls of the clip 1 are riveted with a limiting frame 7 corresponding to the position of the rivet nut 6, as shown in FIG. Figures 1 to 2 As shown, it should be noted that the surface of the clip 1 is a rust-proof surface. Compared with the welding method, the rivet nut 6 is fixed on the clip 1 by riveting to avoid damaging the rust-proof layer on the surface of the clip 1. When installing the clip 1, the two clips 1 are arranged opposite to each other, and the two clips 1 are connected by bolts 8 and rivet nuts 6. The rivet nuts 6 replace the mounting through holes 5 to connect with the bolts 8, which can facilitate the disassembly and assembly of the clip 1. The staff does not need to use nuts and bolts 8 to cooperate with each other for installation. When it is necessary to clamp cables 9 of different specifications, the staff only needs to remove the bolts 8 on one clip 1 to swing the clip 1 to put in the cable 9, and there is no need to remove the bolts 8 on the two clips 1 at the same time, thereby reducing the workload of the staff for disassembly and assembly. Among them, a rivet nut 6 is riveted on the side of one clip 1 facing the other clip 1 at the position of the two mounting through holes 5, and a limit frame 7 is riveted on the side wall of one clip 1 corresponding to the position of the rivet nut 6, as shown in FIG. Figure 3 Another embodiment of the clip 1 is shown, one clip 1 is not provided with a limit frame 7, and the other clip is provided with two limit frames 7. Similarly, the two clips 1 are connected by bolts 8, and the two limit frames 7 are placed between the two clips 1 for easy disassembly and assembly.

[0021] Furthermore, the opening of the limiting frame 7 is arranged outward along the length direction of the accommodating groove 3 so that the rivet nut 6 is accommodated in the limiting frame 7. Figures 1 to 5 As shown, when the two clips 1 are installed, the two limit frames 7 are staggered, and when the two clips 1 clamp the cable 9, the limit frame 7 is between the two clips 1 to prevent the clips 1 from exerting too much pressure on the cable 9 and causing the cable 9 to be squeezed and deformed, and the cable 9 is between the two limit frames 7 to prevent the cable 9 from moving horizontally between the two clips 1, making the cable 9 neat and beautiful, and the opening of the limit frame 7 is facing away from the cable 9 to prevent the sharp opening of the limit frame 7 from scratching the surface of the cable 9, thereby protecting and limiting the cable 9.

[0022] The above are only specific embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
