Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a tensile-resistant power cable. Background Technology

[0002] Cables are typically rope-like structures made up of several or groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being internally energized and externally insulated. Types of cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple strands of conductors and insulation layers, and are used to connect circuits, electrical appliances, etc.

[0003] In existing technologies, the linear expansion coefficient matching degree is low, and cumulative deformation is easily generated in environments with temperature fluctuations or mechanical vibrations, leading to sheath cracking or conductor exposure. Fixed terminals are mostly static interlocking structures, lacking elastic compensation space. After long-term tension, plastic deformation is easily caused, resulting in poor electrical contact. The connection between cable bodies is not additionally fixed, which can easily cause the cable body connection to break after long-term use. Utility Model Content

[0005] Preferably, the filler evenly coats the cable body, and the insulating sleeve is slidably connected to the base through a fixing groove.

[0006] Preferably, the mounting plates are symmetrically distributed at the front and rear ends of the base, and mounting grooves are symmetrically opened at the top of the mounting plates. The caliper pins A are evenly distributed inside the base through the fixing grooves.

[0007] Preferably, the side block is slidably connected to the base, the threaded rod is rotatably connected to the fixed block through the positioning groove, the threaded rod is rotatably connected to the base through the threaded groove, and the top end of the threaded rod is fixedly installed with a rotating block.

[0008] Preferably, the mounting plate has a slot inside, a pad is provided inside the slot, a connecting plate is fixedly installed on the back of the pad, and a cover is fixedly installed on the top of the connecting plate.

[0009] Preferably, the pad is fixed inside the mounting plate by a slot, the connecting plates are evenly distributed at the bottom of the cover, and the connecting plates are slidably connected to the mounting plate.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the mechanical performance and reliability are improved by using a base, mounting plate, mounting groove, fixing groove, jack A, threaded groove, fixing plate, jack B, side block, fixing block, positioning groove, threaded rod and rotating block. The filler evenly covers the cable body to form a flexible buffer layer, which effectively disperses axial tensile force and suppresses local stress concentration. The double-stage locking structure of jack A and fixing groove, and jack B and fixing plate enhances the stability between components. Combined with the fine adjustment mechanism of side block and threaded rod, the cable body is stably fixed, which extends the service life of the cable. It is especially suitable for dynamic load scenarios under complex working conditions.

[0011] 2. In this utility model, the reliability and maintainability of the cable system are optimized by using a slot, a pad, a connecting plate, and a cover. The slot inside the mounting plate, together with the elastic pad, forms an adaptive clamping interface, which not only ensures the positioning accuracy of the cable but also absorbs the stress caused by assembly errors. The sliding linkage mechanism formed by the connecting plate and the cover enables quick assembly and disassembly while maintaining structural rigidity. The flexible nature of the pad effectively prevents hard contact wear between metal parts. The cover forms a physical barrier for key connection parts to prevent the intrusion of external impurities.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Please see Figures 1-3 , Figure 5 This utility model provides a technical solution: a tensile-resistant power cable, comprising a cable body 1; the surface of the cable body 1 is provided with a filler 2 and an insulating sleeve 3; a base 4 is provided at the bottom end of the insulating sleeve 3; an mounting plate 5 is fixedly installed on the surface of the base 4; a fixing groove 7 is formed at the top end of the base 4; a locking pin A8 is provided inside the fixing groove 7; a fixing plate 10 is provided at the top end of the base 4; a locking pin B11 is fixedly installed on the inner wall of the fixing plate 10; a side block 12 is fixedly installed at the bottom end of the fixing plate 10; a fixing block 13 is fixedly installed at the top end of the side block 12; and the fixing block 13... The cable body 1 is uniformly wrapped with filler 2 and the insulation sleeve 3 is slidably connected to the base 4 through the fixing groove 7. The mounting plate 5 is symmetrically distributed at the front and rear ends of the base 4. The top of the mounting plate 5 is symmetrically opened with mounting groove 6. The pin A8 is uniformly distributed inside the base 4 through the fixing groove 7. The side block 12 is slidably connected to the base 4. The threaded rod 15 is rotatably connected to the fixing block 13 through the positioning groove 14. The threaded rod 15 is rotatably connected to the base 4 through the threaded groove 9. The top of the threaded rod 15 is fixedly installed with the rotating block 16.

[0017] like Figure 1 and Figure 3 as well as Figure 4 As shown, a slot 17 is opened inside the mounting plate 5, and a pad 18 is set inside the slot 17. A connecting plate 19 is fixedly installed on the back of the pad 18, and a cover 20 is fixedly installed on the top of the connecting plate 19. The pad 18 is fixed inside the mounting plate 5 through the slot 17. The connecting plates 19 are evenly distributed at the bottom of the cover 20, and the connecting plates 19 are slidably connected to the mounting plate 5.

[0018] The usage and working principle of this device are as follows: First, cut the filler 2 and insulation sleeve 3 on the surface of the cable body 1. Then connect the cable body 1. After connection, wrap it with insulating tape, then place it inside the base 4 through the fixing groove 7. Next, lift the fixing plate 10 and press it down onto the base 4, causing the fixing plate 10 to move the pin B11 to adhere to the top of the insulation sleeve 3. Then, pass the threaded rod 15 through the positioning groove 14, through the fixing block 13 and side block 12, and align it with the threaded groove 9. Then, use a tool to rotate the rotating block 16, causing the threaded rod 15 to rotate downwards through the threaded groove 9 at the top of the base 4. After the threaded groove 9 is fully inserted into the base 4, the clamping pins A8 and B11 can then use the insulating sleeve 3 and filler 2 to fix the cable body 1 between the base 4 and the fixing plate 10. Next, place the base 4 in the desired position and fix it through the mounting groove 6. Finally, pinch the cover 20 to align the connecting plate 19 with the mounting groove 6 and press it down. This will cause the connecting plate 19 to move the clamping pad 18 through the mounting groove 6 and slide it downwards at the top of the mounting plate 5. Once the clamping pad 18 is fixed inside the mounting plate 5 through the clamping groove 17, the clamping pad 18 will then use the connecting plate 19 to hold the cover 20 at the top of the mounting plate 5, thus protecting the fixing bolts.
