Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a pre-installed welding cable connector. Background Technology

[0002] With rapid economic development and accelerated industrialization and urbanization, the demand for electricity continues to grow. This necessitates higher reliability, stability, and security in power systems to meet the ever-increasing electricity demand. As a crucial component of power transmission, the quality and performance of cable connections directly impact the operational efficiency and safety of the power system.

[0003] Fusion splicing of cable joints typically involves inserting the cores of two cables into a pre-placed fusion sleeve, ensuring the cores are correctly positioned and in contact with each other. Then, using specific fusion equipment or processes, the fusion sleeve and cable cores are heated, causing the metal materials of the fusion sleeve and cable cores to melt and fuse together at high temperatures. However, the reserved fusion space can easily allow dust, moisture, etc. to enter after the cable is fused, affecting the normal use of the cable and even causing short circuits.

[0004] To address this issue, we designed a pre-installed fusion splice cable connector. Utility Model Content

[0005] The purpose of this invention is to provide a pre-installed fusion splice cable connector to solve the problems mentioned in the background art.

[0007] Furthermore, a flange is fixedly connected to one end of the threaded ring, a connecting part is fixedly connected to the outer wall of the flange, an iron plate is fixedly connected to the end of the connecting part away from the flange, and a magnet is fixedly connected to one end of the connecting pipe, with the magnet and the iron plate being magnetically connected.

[0008] Furthermore, the number of connecting parts is multiple, arranged in a ring on the flange.

[0009] Furthermore, a bolt is threaded onto the outer wall of the flange, one end of which penetrates the outer wall of the flange and extends into the flange, and a clamping plate is fixedly connected to one end of the bolt.

[0010] Furthermore, a limit block is threaded onto the bolt, and there are two bolts symmetrically arranged on the flange.

[0011] Furthermore, a gasket is provided on each of the two clamping plates facing each other, and the gasket is made of rubber.

[0012] Furthermore, a spring is fixedly connected to the inner wall of the connecting pipe, and a clamping plate is fixedly connected to the other end of the spring.

[0013] Furthermore, the surfaces of both the protective tube and the connecting tube are made of insulating material.

[0014] Compared with the prior art, the beneficial effects of this utility model are: rotating the threaded pattern allows the threaded pattern to be screwed between the threaded ring and the connecting part, and the protective tube is fixed on the periphery of the connecting part by the threaded pattern and the threaded ring, preventing dust and moisture in the air from entering the connecting part after welding, thus preventing the normal use of the welded cable, preventing the cable from being affected by external factors, and improving its service life.

[0015] Compared with the prior art, the beneficial effects of this utility model are: since gaskets are provided on both sides of the clamping plate, the cable is prevented from being worn by the pressure of the clamping plate during clamping, thus protecting the cable and enabling it to be used normally.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 3 This utility model provides a technical solution: a pre-installed fusion splice cable connector, including a connector 1, a T-shaped block 101 fixedly connected to the outer wall of the connector 1, a protective tube 5 provided on the connector 1, a T-shaped groove 501 opened on the inner wall of the protective tube 5, the T-shaped block 101 slidably fastened in the T-shaped groove 501, a cap 3 rotatably connected to the outer wall of the protective tube 5, the outer wall of the cap 3 is provided with a threaded pattern 301, a threaded ring 201 is provided on the outside of the connector 1, and the threaded ring 201 and the threaded pattern 301 are threadedly connected.

[0023] In practice, a T-shaped block 101 is fixedly connected to the outer wall of the connector 1. Simultaneously, a protective tube 5 is provided on the connector 1, and a T-shaped groove 501 is formed on the inner wall of the protective tube 5. The T-shaped block 101 can slide and engage within this T-shaped groove 501, thus connecting the protective tube 5 to the connector 1. Furthermore, a cap 3 is rotatably connected to the outer wall of the protective tube 5, and the outer wall of the cap 3 is provided with threaded lines 301. A threaded ring 201 is also provided on the outside of the connector 1, and the threaded ring 201 is threadedly connected to the threaded lines 301 on the outer wall of the cap 3.

[0024] See Figure 4 As shown, a flange 4 is fixedly connected to one end of the threaded ring 201, a connecting part 2 is fixedly connected to the outer wall of the flange 4, an iron sheet 202 is fixedly connected to the end of the connecting part 2 away from the flange 4, and a magnet 103 is fixedly connected to one end of the pipe 1. The magnet 103 and the iron sheet 202 are magnetically connected.

[0025] In practice, the connecting part 2 and the connecting pipe 1 are brought close to each other. Since the connecting part 2 is provided with an iron sheet 202 and the connecting pipe 1 is provided with a magnet 103, the magnet 103 and the iron sheet 202 are attracted by magnetism, and then they are welded together using welding equipment or process. Since the connecting part 2 is arranged in a ring, there is a gap between each two connecting parts 2 to facilitate the operation of the welding equipment on the cable.

[0026] See Figure 1 There are multiple connecting parts 2, which are arranged in a ring on the flange 4.

[0027] In practice, multiple connecting parts 2 are evenly distributed around the central axis of the flange 4, and are tightly connected to the flange 4 from all directions. This ring-shaped arrangement makes the connection more stable and uniform, better able to withstand forces from all directions, and improves the structural stability and reliability of the entire cable joint. At the same time, the presence of multiple connecting parts 2 also increases the connection points with other components, further enhancing the overall performance of the cable joint.

[0028] See Figure 2 Bolt 401 is threaded on the outer wall of flange 4. One end of bolt 401 penetrates the outer wall of flange 4 and extends into flange 4. One end of bolt 401 is fixedly connected to clamping plate 402. Limiting block 404 is threaded on bolt 401. There are two bolts 401, which are symmetrically arranged on flange 4.

[0029] In practice, rotating the bolt 401 moves the clamping plate 402 inside the flange 4, effectively clamping and fixing the cable placed inside the flange 4. The presence of the limiting block 404 restricts the movement range of the bolt 401, preventing excessive tightening of the bolt 401 and causing excessive compression damage to the cable. The two symmetrically arranged bolts 401 can clamp the cable simultaneously from two opposite directions, making the clamping more stable and reliable.

[0030] See Figure 2 Each of the two clamping plates 402 has a gasket 403 on its opposite side, and the gasket 403 is made of rubber.

[0031] In practical implementation, on the one hand, rubber has a certain degree of elasticity. When the clamping plate 402 clamps the cable, the gasket 403 can act as a buffer, preventing the clamping plate 402 from directly contacting the cable and causing damage. On the other hand, the rubber gasket 403 can increase the friction between the gasket and the cable, making the cable more stable when clamped and less prone to slipping or loosening. This design further improves the reliability and safety of the cable joint, ensuring the firmness and stability of the cable connection.

[0032] See Figure 3 A spring 102 is fixedly connected to the inner wall of the connector 1, and a clamping plate 402 is fixedly connected to the other end of the spring 102.

[0033] In practical implementation, the presence of spring 102 allows the clamping plate 402 a certain amount of elastic movement. When the cable is inserted into the connector 1, spring 102 can adjust its extension and retraction to a certain extent according to the diameter of the cable, thereby enabling the clamping plate 402 to better adapt to cables of different sizes and ensuring a tighter and more stable clamping of the cable. At the same time, the elasticity of spring 102 can also buffer the impact of external vibration or shock on the cable to a certain extent, protecting the cable from damage and improving the reliability and service life of the cable joint.

[0034] See Figure 1 The surfaces of both the protective tube 5 and the connecting tube 1 are made of insulating material.

[0035] In practical implementation, on the one hand, the insulation material effectively prevents current leakage and the risk of electric shock, improving the safety of the cable joint during use. When the cable joint is energized, the insulation material ensures that the current is transmitted normally inside the cable and is not conducted out through the surface of the protective tube 5 or the connecting tube 1, thus avoiding potential hazards to the surrounding environment and personnel. On the other hand, the insulation material also protects the internal structure of the cable joint. It prevents external dust, moisture, humidity, and other impurities from entering the cable joint, thereby reducing the possibility of electrical faults and damage caused by impurities. At the same time, the insulation material also has a certain degree of corrosion resistance and wear resistance, which can extend the service life of the cable joint.

[0036] Working principle: Two cables to be fused are respectively introduced into flange 4 and connector 1, abutting against clamping plate 402. Since gaskets 403 are provided on opposite sides of clamping plate 402, the pressure from clamping plate 402 during clamping prevents cable wear and protects the cables for normal use. Ensure the points where the two cables need to be fused are in contact. Then, bring connecting part 2 and connector 1 closer together. Since connecting part 2 has an iron plate 202 and connector 1 has a magnet 103, the magnet 103 and iron plate 202 are attracted magnetically. Then, fusion welding equipment or processes are used to fuse them. Because connecting part 2 is annular, a gap is left between every two connecting parts 2. This facilitates the operation of the fusion splicing equipment on the cable. After the fusion is completed, the protective tube 5 set on the connector 1 is pushed and slid into the connecting part 2. Since the T-shaped block 101 is slidably engaged in the T-shaped groove 501, the protective tube 5 can slide back and forth without falling off. The threaded pattern 301 comes into contact with the threaded ring 201. Then, the threaded pattern 301 is rotated so that it is screwed into the space between the threaded ring 201 and the connecting part 2. The threaded pattern 301 and the threaded ring 201 fix the protective tube 5 to the outside of the connecting part 2, preventing dust and moisture in the air from entering the connecting part 2 after the fusion, thus affecting the normal use of the fused cable, preventing the cable from being affected by the outside world, and improving its service life.
