Description

Technical Field

[0001] This utility model relates to the field of wire clamp technology, specifically to a tension wire clamp. Background Technology

[0002] Wedge-shaped tension clamps secure conductors and transmit tension through a wedge-shaped structure, preventing loosening and vibration and ensuring stable operation of power lines. Existing technology, such as the utility model patent with publication number CN102044854B, discloses a wedge-shaped tension clamp with two semi-covers and two semi-clamping blocks inside. The conductor is fixed between the two semi-clamping blocks. This connection method results in the conductor only being stressed on the two sides with the semi-clamping blocks, leaving gaps at the connection point. Over time, the conductor insulation layer, after being compressed and deformed, can easily delaminate from the internal metal conductor, causing the outer insulation layer to slip and lose its grip on the metal conductor. Such products are prone to insulation layer slippage, thinning, or even breakage during long-term use, leading to the entire conductor slipping and increasing the risk of electrical safety accidents. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defects in the prior art that the insulation layer is prone to slippage, thinning or even breakage, and the internal conductor cannot be held, causing the entire wire to slip. Thus, a tension clamp is provided that makes the wire bear force evenly and prevents the insulation layer of the wire from separating from the metal conductor.

[0004] Therefore, this utility model provides a tension clamp, including at least four inner clamping blocks wrapped around the outside of the conductor. The inner clamping blocks are wrapped with a conical body. The conical body is provided with a first opening for inserting the inner clamping blocks, and a second opening is provided on the side of the conical body opposite to the opening for the conductor to pass through.

[0005] Furthermore: the inner clamping block is provided with a fixing guide for connecting adjacent inner clamping blocks, the fixing guide is arranged in a ring structure, and a positioning structure for fixing the two is provided between the fixing guide and the inner clamping block.

[0006] Furthermore, the positioning structure includes a positioning bead disposed on one side of the fixed guide or inner clamping block and a positioning groove disposed on the other side that can be adapted to the positioning bead.

[0007] Furthermore: the positioning bead is disposed on the fixed guide member, and the positioning groove is disposed on the inner clamping block.

[0008] Furthermore, the inner clamping block and the inner side of the fixed guide are provided with several anti-slip teeth that abut against the outer side of the wire.

[0009] Furthermore: the conical body is integrally formed, and the two sides of the conical body are provided with extension ears that connect to the hanging plate.

[0010] The technical solution of this utility model has the following advantages: 1. This utility model provides a tension clamp with four inner clamping blocks. The conductor is installed inside the inner clamping blocks, and the four inner clamping blocks form a surrounding structure that wraps around the conductor. Then, the installed inner clamping blocks and the conductor are inserted through the first opening and the conductor is exited through the second opening. Compared with the prior art, the four inner clamping blocks can evenly press the conductor from four directions, so that each surface can be subjected to uniform force. This can effectively prevent the outer insulation layer of the conductor from separating from the inner metal conductor after long-term use, thus preventing slippage between the two.

[0014] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] Example This embodiment provides a tension clamp, including at least four inner clamping blocks 1 wrapped around the outside of a conductor 10. The inner clamping blocks 1 are wrapped with a conical body 2. The conical body 2 is provided with a first opening 21 for inserting the inner clamping blocks 1, and a second opening 22 for the conductor 10 to pass through on the side of the conical body 2 opposite to the opening.

[0019] The specific improvements mentioned above are as follows: Figures 1-4 As shown, there are four inner clamping blocks 1. The wire 10 is installed inside the inner clamping blocks 1. The four inner clamping blocks 1 form a surrounding structure that encloses the wire 10. Then, the installed inner clamping blocks 1 and the wire 10 are inserted through the first opening 21 and the wire 10 is inserted through the second opening 22. Compared with the prior art, by setting four inner clamping blocks 1, the wire 10 can be pressed evenly from four directions, so that each surface can be subjected to uniform force. This can effectively prevent the insulation layer on the outside of the wire 10 from separating from the internal metal conductor after long-term use, thus preventing the problem of slippage between the two.

[0020] Based on the above embodiments: the inner clamping block 1 is provided with a fixed guide 3 for connecting adjacent inner clamping blocks 1, the fixed guide 3 is arranged in a ring structure, and a positioning structure 4 for fixing the two is provided between the fixed guide 3 and the inner clamping block 1.

[0021] Based on the above embodiments: the positioning structure 4 includes a positioning bead 41 disposed on one side of the fixed guide 3 or the inner clamping block 1 and a positioning groove 42 disposed on the other side and adapted to the positioning bead 41.

[0022] Based on the above embodiments: the positioning bead 41 is disposed on the fixed guide member 3, and the positioning groove 42 is disposed on the inner clamping block 1.

[0023] The specific improvements mentioned above are as follows: Figures 3-5 As shown, in order to ensure proper positioning between the inner clamping block 1 and the wire 10, a fixed guide 3 is provided on the side of the inner clamping block 1 near the first opening 21. A positioning bead 41 is provided on the fixed guide 3, and a positioning groove 42 that matches the positioning bead 41 is provided on the inner clamping block 1. During installation, the wire 10 can be passed through the fixed guide 3 first, and then the positioning groove 42 on the inner clamping block 1 can be matched with the positioning bead 41 in sequence. After the inner clamping block 1 is installed, the wire 10 is first passed through the first opening 21, and then the entire inner clamping block 1 and the fixed guide 3 are passed through the first opening 21. Finally, the wire 10 is passed out through the second opening 22, and the entire inner clamping block 1 and the fixed guide 3 are fixed inside the conical body 2.

[0024] Based on the above embodiments: the inner clamping block 1 and the inner side of the fixed guide 3 are provided with a plurality of anti-slip teeth 5 that abut against the outer side of the wire 10.

[0025] The specific improvements mentioned above are as follows: Figure 5 As shown, by setting the anti-slip teeth 5, the friction between the inner clamping block 1 and the inner side of the guide fixing part can be effectively increased, making the connection between the two more tight.

[0026] Based on the above embodiments: the conical body 2 is integrally formed, and the two sides of the conical body 2 are provided with extension ears 6 that are connected to the hanging plate 7.

[0027] The specific improvements mentioned above are as follows: Figure 6 As shown, the conical body 2 is integrally formed, and the inner clamping block 1 and the fixed guide 3 are embedded inside the conical body 2. The conical body 2 can apply a uniform clamping force to the inner clamping block 1 from all sides, thereby ensuring that the force applied by the inner clamping block 1 to the wire 10 is also uniform, and ultimately it can better hold the wire 10.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
