Description

Technical Field

[0001] The utility model relates to the technical field of power cable connection, in particular to a connecting hardware used for power cable connection. Background Art

[0002] Power cables are wires and cables used to transmit and distribute electrical energy. They typically consist of a conductor, insulation, and sheath. Simply connecting the conductors together often fails to ensure good conductivity and stability. Using splicing hardware, however, provides a secure connection, ensuring smooth current flow, reducing contact resistance, and preventing heat, energy loss, and even failures caused by poor connections.

[0003] In the prior art, some connecting hardware usually inserts the conductors of two cables into the crimping tube of the connecting hardware to ensure that the conductors are fully inserted and aligned, and uses a crimping tool to crimp the crimping tube. By applying pressure, the crimping tube is deformed to tightly wrap the cable conductor to achieve electrical connection. However, the cable will have position deviation when inserted into the crimping tube, making it difficult to ensure that the conductors are fully inserted and aligned. This will result in some conductors not being effectively wrapped, the connection being loose, and easy to loosen when subjected to force or vibration, affecting the stability of power transmission. In addition, once the crimping is completed, the existing crimping method is difficult to adjust, which reduces the flexibility and accuracy of installation. Therefore, in response to the above shortcomings, a connecting hardware for power cable connection is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0023] Reference Figure 1 、 Figure 2 and Figure 4The present invention provides an embodiment of a connecting fitting for connecting power cables, comprising a connecting mold 1, the top of which is fixedly connected to a receiving block 2. The receiving block 2 is square-shaped and has a threaded structure inside that matches a threaded column 3. The top of the threaded column 3 is fixedly connected to a control assembly that is easy to twist. The control assembly includes a control disk 4. The control disk 4 is a circular structure, and its bottom end is firmly fixed to the top of the threaded column 3. The outside of the control disk 4 is fixedly connected to two rotating shafts 5. The rotating shafts 5 are solid columnar structures. The outsides of the two rotating shafts 5 are fixedly connected to portable operating rods 6. The portable operating rods 6 are convenient for operators to operate.

[0024] Reference Figure 1 、 Figure 2 and Figure 3 The bottom end of the threaded column 3 is rotatably connected to a clamping block 7. The material of the clamping block 7 is spring steel, which has good elasticity and strength. The bottom end of the clamping block 7 is fixedly connected to a pressure block 8. The material of the pressure block 8 is rubber. The rubber pressure block 8 can play a good role in buffering and increasing friction. The bottom end of the connecting mold 1 is fixedly connected to a telescopic rod 9. The telescopic rod 9 is a telescopic structure. The outside of the telescopic rod 9 is provided with a spring 10. The spring 10 has a certain elastic coefficient. The top of the telescopic rod 9 is fixedly connected to a clamping block 2 11. The clamping block 2 11 is a component of a specific shape. One end of the spring 10 is fixedly connected to the bottom end of the clamping block 2 11, and the other end is fixedly connected to the bottom end of the connecting mold 1. The outside of the clamping block 7 is slidably connected to the inside of the clamping block 2 11, and the outside of the pressure block 8 is in contact with the inside of the top of the clamping block 2 11;

[0025] The left and right sides of the connecting mold 1 are both threadedly connected with a connecting assembly for fixing. The connecting assembly includes a connecting rod 12. The connecting rod 12 is a long strip structure. The adjacent sides of the two connecting rods 12 are respectively threadedly connected to the inside of the left and right sides of the connecting mold 1. The outside of the connecting rod 12 is fixedly connected with a rotating disk 13. The rotating disk 13 is a circular disk structure. The outside of the rotating disk 13 is fixedly connected with a control rod 14. The control rod 14 facilitates the operator to rotate the rotating disk 13. The far sides of the two connecting rods 12 are respectively threadedly connected to the adjacent sides of the two connecting columns 15. The far sides of the two connecting assemblies are both threadedly connected to the connecting columns 15. The connecting columns 15 are columnar structures of a specific shape. One side of the rotating disk 13 is in contact with one side of the connecting mold 1, and the other side of the rotating disk 13 is in contact with one side of the connecting column 15, which plays the role of fixing and connecting.

[0026] The upper and lower sides of the connecting column 15 are fixedly connected to the inside of the tightening assembly for limiting the position. The tightening assembly includes a telescopic rod 2 16. The telescopic rod 2 16 is a telescopic columnar structure, and its exterior is fixedly connected to the interior of the connecting column 15. The exterior of the telescopic rod 2 16 is provided with a spring 2 17. The spring 2 17 has a certain elasticity. The adjacent side of each two telescopic rods 2 16 is fixedly connected with a tightening block 18. The tightening block 18 is a component of a specific shape and is used to tighten the cable.

[0027] Working Principle: First, place the two cables into the two connecting posts 15, respectively. The tightening assembly within the posts 15 then begins to function. The spring 17 on the telescopic rod 16 is compressed, pushing the tightening block 18 toward the cables, securing them within the posts 15. This ensures that the cables are positioned precisely during connection, preventing misalignment and ensuring that the conductors are fully inserted and aligned, resulting in a tighter connection.

[0028] Next, the connecting assembly is operated to connect the connecting post 15 to the connecting mold 1. Rotating the control lever 14 rotates the rotating disk 13, causing the connecting rod 12 to rotate along the threaded path within the connecting mold 1 and the connecting post 15, thereby connecting the connecting post 15 to the connecting mold 1. One side of the rotating disk 13 contacts one side of the connecting mold 1, while the other side contacts one side of the connecting post 15, providing both securement and connection.

[0029] Then, the cable is clamped. The control disk 4 is turned, and the control disk 4 drives the threaded column 3 to rotate. The threaded column 3 rotates and moves downward in the inner thread of the receiving block 2. The threaded column 3 drives the clamping block 17 to move downward, and the clamping block 17 slides inside the clamping block 2 11. The clamping block 17 is made of spring steel and has a certain elasticity and strength. The clamping block 8 at the bottom end of the clamping block 17 is in contact with the top inner part of the clamping block 2 11. The clamping block 8 is made of rubber and plays a role in buffering and increasing friction. As the threaded column 3 is continuously turned, the clamping block 17 drives the cable connection to move closer to the clamping block 2 11. At the same time, the spring 10 outside the telescopic rod 19 inside the bottom end of the connecting mold 1 is compressed. One end of the spring 10 is fixedly connected to the bottom end of the clamping block 2 11, and the other end is fixedly connected to the inner bottom end of the connecting mold 1. The elastic force of spring 10 causes clamping block 1 7 and clamping block 2 11 to exert force on each other, further clamping the cable, thereby greatly improving the flexibility and accuracy of installation.

[0030] When maintenance or inspection of the connection is required, the control lever 14 is rotated again, driving the rotating disk 13 to rotate in the opposite direction, so that the connecting rod 12 can loosen the connecting column 15 from the connecting mold 1 through the thread. The operator can quickly perform maintenance work. After maintenance is completed, the connecting column 15 and the connecting mold 1 can be reconnected by rotating the control lever 14, reducing maintenance time and workload.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
