Description

Technical Field

[0001] The utility model relates to the technical field of electric power hardware, in particular to a tension wire clamp with a limiting structure. Background Art

[0002] A tension clamp is a piece of hardware used to fix the conductor to withstand the conductor tension and hang the conductor on a tension string or pole tower.

[0003] The wedge-shaped tension clamp is a widely used type of tension clamp. The existing wedge-shaped tension clamp usually includes a clamp body and a core disposed in the clamp body. The core moves in the wedge-shaped cavity of the clamp body to achieve the clamping and loosening of the cable. Figure 1 shown.

[0004] In the prior art, there is a patent with a patent authorization announcement number of CN 219458623 U, which discloses an interlocking self-locking wedge for an overhead insulated conductor.

[0005] Due to the lack of a fixed limiting structure between the sandwich core and the sandwich body, after the sandwich core has completed clamping the cable, if the sandwich core slides again during use, the cable will fall out, thus affecting the use of the product. Utility Model Content

[0006] In view of the problems pointed out in the background technology, the utility model proposes a tension clamp with a limiting structure.

[0007] The technical solution of the utility model is achieved in this way:

[0008] A tension clamp with a limiting structure comprises a clamp body, a core is arranged in the clamp body, connecting parts are respectively arranged on both sides of one end of the clamp body, connecting parts are provided with connecting holes, a U-shaped pull ring, both ends of the pull ring are respectively connected to the connecting holes on both sides of the clamp body, both ends of the pull ring are respectively threadedly connected with fastening nuts, and a limiting plate is also included, the limiting plate is provided with through holes corresponding to the two ends of the pull ring, the limiting plate is provided with through holes corresponding to the core, the pull ring is threadedly connected with a limiting nut, and the limiting plate is located between the limiting nut and the core.

[0009] The utility model is further configured such that the width of the perforation gradually increases from one end to the other end, one end of the sandwich can enter the perforation from one end of the perforation, and the other end of the perforation can prevent one end of the sandwich from passing through the perforation.

[0010] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0011] (1) In the technical solution of the present application, a limiting plate is provided on the pull ring, and the limiting plate forms a limit on the sandwich, thereby preventing the sandwich from escaping from the sandwich body.

[0012] (2) In the technical solution of the present application, when the limiting nut is gradually tightened, one end of the core gradually enters the through hole, causing the core to gradually contract, further forming a clamping fixation for the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] For reference Figure 1-3 The utility model is described as follows:

[0020] Embodiment 1: A tension clamp with a limiting structure, comprising a clamp body 1, a core 2 is arranged inside the clamp body 1, connecting parts 3 are arranged on both sides of one end of the clamp body 1, connecting parts 3 are arranged on connecting holes 31, and a U-shaped pull ring 4 is also included, the two ends of the pull ring 4 are respectively connected to the connecting holes 31 on both sides of the clamp body 1, the pull ring 4 is a rigid structure made of metal material, the two ends of the pull ring 4 are respectively provided with external threads, the two ends of the pull ring 4 are respectively threadedly connected with fastening nuts 5, and the cable is clamped on the inner side of the core 2. The above is the prior art, and the following is the improved technical solution of this application:

[0021] It also includes a limiting plate 6, which is provided with through holes 61 corresponding to the two ends of the pull ring 4. The two ends of the pull ring 4 pass through the through holes 61. The pull ring 4 is threaded with a limiting nut 7. The limiting plate 6 is located between the limiting nut 7 and the core 2. When the limiting nut 7 is tightened, the limiting plate 6 is against the core 2, which can limit the core 2 from escaping from the clamp body 1.

[0022] The limiting plate 6 is provided with a through hole 62 corresponding to the sandwich core 2, and the through hole 62 is for the cable to pass through.

[0023] The width of the through hole 62 is gradually increased from one end to the other end. The cross-section of the core 2 is rectangular, and the cross-section of the through hole 62 is also rectangular. The thickness of the core 2 is equal to the length of the through hole 62 in the thickness direction of the core 2. The width of the other end of the through hole 62 is greater than the width of one end of the core 2, and the width of one end of the through hole 62 is less than the width of one end of the core 2. In this way, the core 2 can enter the through hole 62, and as the width of the through hole 62 gradually decreases, one end of the core 2 gradually converges to further clamp the cable.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
