Description

Technical Field

[0001] This utility model relates to the technical field of cable end protective covers, specifically a cable end protective cover. Background Technology

[0002] 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, and so on. They are all composed of single or multiple strands of conductors and insulation layers, used to connect circuits and electrical appliances. To prevent short circuits and leakage caused by accidental contact of the wires inside the cable head, and to prevent flashover from dust, dirt, and condensation, protective devices are often installed on the cable head.

[0003] As cable end protective covers are used, the material gradually ages, becoming brittle, hardened, or losing elasticity. Aged covers struggle to maintain their original fastening properties and are prone to loosening or even detachment when subjected to external forces or environmental factors such as wind or vibration. This results in the cable end losing effective protection, increasing safety hazards. Therefore, we propose a new type of cable end protective cover. Utility Model Content

[0004] The purpose of this utility model is to provide a cable end protective cover to solve the problem mentioned in the background art that the cable end is prone to loosening or even falling off due to the influence of external environmental factors, thereby causing the cable end to lose effective protection and increasing safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable end protective cover, comprising a protective cover shell and a slot, the slot being formed inside the protective cover shell, limit rings being fixedly installed on both sides of the inner wall of the slot, positioning plates being fixedly installed on both sides of the surface of the limit rings, a fixing block being fixedly installed above the positioning plates, a tension spring being movably installed at the center of one side of the bottom surface of the fixing block, a connecting rod being fixedly connected to one side of the surface of the tension spring, a movable rod being movably connected to one side of the surface of the connecting rod, a sliding rod being fixedly connected to the bottom of the movable rod, a pull rod being fixedly connected to one side of the surface of the sliding rod, a buckle being fixedly connected to one side of the surface of the pull rod, and a tension ring being provided on one side of the surface of the fixing block.

[0006] The protective cover has a base fixedly installed at the bottom, a top cover rotatably connected to the top of the protective cover, a rotating ring rotatably connected at the intersection of the top cover and the protective cover, and a buffer pad is provided on the top inner side of the top cover.

[0007] The limiting ring and the fixing block are symmetrically distributed around the inside of the slot. A sliding groove is opened at the center of the surface of the fixing block, and the sliding groove is parallel and corresponding to the pull rod.

[0008] The movable rod is adjusted by rotating on the surface of the connecting rod via a pull rod and a slide rod, which causes the tension spring to drive the connecting rod to extend and retract on the bottom surface of the fixed block.

[0009] The tension clasp is telescopically connected to the surface of the fixed block on one side, and its extension and retraction are adjusted at both ends of the top inside the slot by a tension spring and a connecting rod.

[0010] The protective cover has slots on both sides of the upper surface of the outer shell, which are engaged with the buckles.

[0011] The bottom of the buffer pad is perpendicular to the surface of the elastic retaining ring.

[0012] This utility model has at least the following beneficial effects:

[0013] 1. The design of the protective cover, including slots, limiting rings, positioning plates, and buckles, simplifies the installation process. Simply place the cable end into the slot, and using the linkage of the movable rod, sliding rod, and pull rod, along with the adjustment of the tension spring, the buckle can be easily engaged with the buckle groove on the upper surface of the protective cover. No additional tools are required, greatly improving installation efficiency and reducing installation difficulty.

[0014] 2. The limiting rings and fixing blocks are symmetrically distributed around the inside of the slot. The tension of the locking rings at both ends of the top inside the slot allows for a tight fit to the cable end, ensuring a secure connection between the protective cover and the cable end. Simultaneously, the tension springs can be elastically adjusted according to the actual size of the cable end, further enhancing the reliability of the fixation. Even under external vibration or other forces, it effectively prevents the protective cover from loosening or falling off.

[0015] 3. The buffer pad installed on the top inner side of the top cover can buffer the impact when the protective cover is subjected to external impact, reducing the impact force on the cable end. The bottom of the buffer pad is perpendicular to the surface of the elastic retaining ring, further enhancing the buffering effect, effectively protecting the cable end from damage, and improving the safety and stability of cable operation.

[0023] 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.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a cable end protective cover, including a protective cover shell 100 and a slot 200. The slot 200 is formed inside the protective cover shell 100. Limiting rings 201 are fixedly installed on both sides of the inner wall of the slot 200. Positioning plates 202 are fixedly installed on both sides of the surface of the limiting rings 201. A fixing block 203 is fixedly installed above the positioning plate 202. A tension spring 205 is movably installed at the center position of one side of the bottom surface of the fixing block 203. A connecting rod 206 is fixedly connected to one side of the surface of the tension spring 205. A movable rod 207 is movably connected to one side of the surface of the connecting rod 206. The rod 207 is rotated and adjusted on the surface of the connecting rod 206 via the pull rod 209 and the slide rod 208, so that the tension spring 205 drives the connecting rod 206 to extend and retract on the bottom surface of the fixed block 203. The bottom of the movable rod 207 is fixedly connected to the slide rod 208, and the pull rod 209 is fixedly connected to one side of the surface of the slide rod 208. The buckle 210 is fixedly connected to one side of the surface of the pull rod 209. The tension ring 204 is provided on one side of the surface of the fixed block 203. The tension ring 204 is extended and retracted on one side of the surface of the fixed block 203, and is extended and retracted at both ends of the top inside the slot 200 via the tension spring 205 and the connecting rod 206.

[0025] A base 101 is fixedly installed at the bottom of the protective cover shell 100. The upper surface of the protective cover shell 100 has fastening grooves on both sides, which are corresponding to the buckles 210 for snapping. A top cover 102 is rotatably connected to the top of the protective cover shell 100. A rotating ring 103 is rotatably connected at the intersection of the top cover 102 and the protective cover shell 100. A buffer pad 104 is provided on the top inner side of the top cover 102. The bottom of the buffer pad 104 is perpendicular to the surface of the tensioning ring 204.

[0026] The limiting ring 201 and the fixing block 203 are symmetrically distributed around the inside of the slot 200. A sliding groove is provided at the center of the surface of the fixing block 203, and the sliding groove is parallel and corresponding to the pull rod 209.

[0027] Working principle: Align the cable end with the slot 200 and insert it. Guided by the limiting ring 201, the cable end is accurately positioned. The positioning plate 202 helps installers determine the position of the cable end, ensuring installation accuracy.

[0028] After the cable end is inserted, push the movable rod 207. The movable rod 207 rotates around the connecting rod 206, causing the sliding rod 208 and the pull rod 209 to move. Since the groove at the center of the surface of the fixed block 203 is parallel and corresponds to the pull rod 209, the pull rod 209 moves smoothly within the groove, eventually causing the buckle 210 to move towards the buckle slot on the upper surface of the protective cover 100 and complete the engagement. At the same time, the rotation of the movable rod 207 compresses the tension spring 205, causing the connecting rod 206 to retract on the bottom surface of the fixed block 203. This action pulls the tension ring 204 to extend and retract towards the cable end, tightly fitting the surface of the cable end.

[0029] The limiting retaining ring 201 and the fixing block 203 are symmetrically distributed around the inside of the retaining groove 200, constraining the cable end from multiple directions. The telescopic adjustment of the tension retaining ring 204 at both ends of the top inside the retaining groove 200, in conjunction with the limiting retaining ring 201, ensures a tight fit between the protective cover and the cable end, resulting in a stable connection. When subjected to external vibrations or other external forces, due to the elastic adjustment of the tension spring 205, the tension retaining ring 204 can adapt to the slight displacement of the cable end, always maintaining a tight fixation on the cable end and preventing the protective cover from loosening or falling off.

[0030] When the protective cover is subjected to external impact, the top cover 102 bears the impact force first. The buffer pad 104 on the inner top of the top cover 102 begins to function, absorbing part of the impact force through its own elastic deformation. Since the bottom of the buffer pad 104 is perpendicular to the surface of the tensioning ring 204, the buffer pad 104 further disperses the impact force onto the tensioning ring 204. When under force, the tensioning ring 204, with the help of the elasticity of the tensioning spring 205, performs secondary buffering and dissipation of the impact force, thereby significantly reducing the impact force transmitted to the cable end, effectively protecting the cable end from damage, and ensuring the safety and stability of cable operation.

[0031] The top cover 102 can be easily disassembled from the protective cover housing 100 by rotating the ring 103, and the tension ring 204 can be reset, so that it can be reused. The operation is convenient and simple.
