Description

Technical Field

[0001] This utility model relates to the field of cable head technology, and specifically to a reinforced cable head. Background Technology

[0002] Cable terminations are key components in cable lines used to connect cable conductors, restore insulation, provide sealing protection, and mechanically secure the cable. They are typically installed at the end (terminal head) or in the middle (intermediate joint) of the cable to ensure a safe and reliable connection between the cable and equipment, other cables, or conductors.

[0003] In existing technologies, the connection between cables and cable heads mainly relies on two methods: one is to use crimping pliers to perform hexagonal crimping, which uses mechanical pressure to cause plastic deformation of the contact surface between the conductor and the terminal, forming a stable connection; the other is to use solder or silver-copper solder to fuse the metal, which achieves metallurgical bonding between the conductor and the terminal by melting the metal at high temperature.

[0004] However, both methods have significant drawbacks. The plastic deformation of the crimping method is an irreversible process, and the original structure must be destroyed during disassembly. Repeated crimping will lead to coarsening of the grains on the contact surface and an increase in resistance. The high-temperature operation of the welding method is prone to conductor oxidation and insulation carbonization. Especially during repeated disassembly and assembly, the solder becomes more brittle and is prone to cracking or poor soldering. In addition, the interconnection between cable heads still commonly uses these two traditional processes, which are not only cumbersome and inefficient, but also have a high material loss rate. In long-term use, the decline in contact reliability may cause local overheating, accelerate the aging of cable insulation, and ultimately shorten the overall service life. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a reinforced cable head. This head utilizes a spring-driven arc-shaped plate to adaptively clamp the cable, combined with a heat-shrink sleeve for sealing. This effectively overcomes the problems of increased contact resistance and insulation aging caused by loose contact or seal failure in traditional crimping / welding processes. Furthermore, the plug and retaining ring employ a threaded locking design, enabling quick plug-and-play connection between the cable head and the equipment. This significantly simplifies the cumbersome procedures of traditional crimping and welding, and substantially improves on-site maintenance efficiency.

[0006] The purpose of this utility model is achieved by the following technical solution: a reinforced cable head, including a cable head, a plug two fixedly connected inside the cable head, a fixing plate fixedly connected to the end of the cable head away from the plug two, a fixing component provided inside the fixing plate, a reinforced dustproof component provided on the cable head, and a quick connection component provided at the end of the cable head away from the reinforced dustproof component.

[0007] In one optional embodiment, the fixing assembly includes a plurality of fixing boxes threadedly connected to a fixing plate, a fixing post fixedly connected to the fixing box, a rotating ring rotatably connected to the fixing box, and a spring with one end connected to the fixing post. The other end of the spring is fixedly connected to the rotating ring. A plurality of rotating plates arranged in a circular array are mounted on the rotating ring. The rotating plates are rotatably connected to the rotating ring. An arc-shaped plate is fixedly connected to one end of the rotating plate. A connecting post is fixedly connected to the rotating ring. A movable block is fixedly connected to one end of the connecting post. The movable block is slidably connected to the fixing box.

[0008] In one optional embodiment, the reinforced dustproof component includes a dustproof cover slidably connected to the cable head, a cross-shaped dustproof ring arranged circumferentially on the dustproof cover, a swivel ring threadedly connected to the cable head rotatably connected to the dustproof cover, a heat-shrink sleeve connected to the cable head on the dustproof cover, and a connecting cable disposed within the cross-shaped dustproof ring.

[0009] In one alternative implementation, when the moving block moves closer to the fixed post, the rotating ring will cause the arc-shaped plates on the rotating plate to move away from each other, and when the moving block moves away from the fixed post, the rotating ring will cause the arc-shaped plates on the rotating plate to move closer to each other.

[0010] In one alternative embodiment, the surface of the curved plate is provided with an anti-slip layer.

[0011] In one alternative embodiment, the other end of the rotating plate is rotatably connected to a fixed box.

[0012] In one alternative implementation, the star-shaped dustproof ring undergoes elastic deformation according to the cable diameter, conforming to the surface of cables of different diameters.

[0013] In one optional embodiment, the quick-connect assembly includes a connecting ring connected to the end of the cable head away from the heat shrink sleeve, a plug first that is inserted into the connecting ring is fixedly connected to the connecting ring, a retaining ring is threadedly connected to the connecting ring, a connector connected to the plug first is movably fixedly connected to the retaining ring, and a retaining head is fixedly connected to the end of the retaining ring away from the connector.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The cable is self-clamped by a spring-driven arc plate, combined with the sealed wrapping of heat shrink tubing, which effectively solves the problems of increased contact resistance and insulation aging caused by loose contact or sealing failure in traditional crimping / welding.

[0016] 2. The threaded locking design of the plug and the retaining ring enables quick insertion and removal of the cable head and the equipment, solving the problems of cumbersome and inefficient traditional crimping or welding operations and improving the speed of on-site maintenance.

[0031] Please refer to Figure 1-9 A reinforced cable head includes a cable head 1, a plug 4 fixedly connected inside the cable head 1, a fixing plate 21 fixedly connected to the end of the cable head 1 away from the plug 4, a fixing component disposed within the fixing plate 21, a reinforced dustproof component disposed on the cable head 1, and a quick-connect component disposed at the end of the cable head 1 away from the reinforced dustproof component. This design significantly improves the overall performance of the cable head, including connection stability, sealing, and ease of operation, by integrating fixing, dustproofing, and quick-connect functions.

[0032] In a preferred embodiment of this invention, the fixing assembly includes several fixing boxes 22 threadedly connected to a fixing plate 21, fixing posts 23 fixedly connected within the fixing boxes 22, a rotating ring 25 rotatably connected to the fixing boxes 22, and a spring 24 with one end connected to the fixing post 23. The other end of the spring 24 is fixedly connected to the rotating ring 25. Several rotating plates 26 arranged in a circular array are mounted on the rotating ring 25, and the rotating plates 26 are rotatably connected to the rotating ring 25. An arc-shaped plate 29 is fixedly connected to one end of the rotating plate 26. A connecting post 27 is fixedly connected to the rotating ring 25, and a moving block 28 is fixedly connected to one end of the connecting post 27. The moving block 28 is slidably connected to the fixing box 22. By utilizing the elasticity of the spring and the linkage of the rotating mechanism, the arc-shaped plate achieves adaptive clamping of the cable, improving the stability and reliability of the connection.

[0033] In a preferred embodiment of this invention, the reinforced dustproof component includes a dust cover 210 slidably connected to the cable head 1, a circumferential array of star-shaped dustproof rings 211 on the dust cover 210, a rotatable ring 212 threadedly connected to the cable head 1 on the dust cover 210, a heat-shrink sleeve 213 connected to the cable head 1 on the dust cover 210, and a connecting cable 214 disposed within the star-shaped dustproof rings 211. The double-sealing design of the star-shaped dustproof rings and the heat-shrink sleeve effectively prevents the intrusion of dust and moisture, protecting the insulation performance of the cable connection.

[0034] In a preferred embodiment of this invention, when the moving block 28 moves closer to the fixed post 23, the rotating ring 25 causes the arc-shaped plates 29 on the rotating plate 26 to move away from each other; conversely, when the moving block 28 moves away from the fixed post 23, the rotating ring 25 causes the arc-shaped plates 29 on the rotating plate 26 to move closer together. This simplifies and speeds up cable installation and removal while ensuring a uniform distribution of clamping force.

[0035] In a preferred embodiment of this invention, an anti-slip layer is provided on the surface of the curved plate 29. The anti-slip layer increases the friction between the curved plate and the cable, further stabilizing the cable connection and preventing poor contact caused by slippage.

[0036] In a preferred embodiment of this invention, the other end of the rotating plate 26 is rotatably connected to the fixed box 22. The double-end rotating design makes the movement of the rotating plate more flexible and stable, improving the overall performance and durability of the fixing assembly.

[0037] In a preferred embodiment of this invention, the star-shaped dustproof ring 211 elastically deforms according to the cable diameter, conforming to the surface of cables of different diameters. This feature allows the cable head to adapt to various cable specifications, enhancing its versatility and flexibility.

[0038] Please refer to Figure 9In a preferred embodiment of this utility model, the quick-connect assembly includes a connecting ring 31 connected to the end of the cable head 1 away from the heat shrink sleeve 213. A plug 32, which is inserted into the plug 4, is fixedly connected to the connecting ring 31. A fixing ring 33 is threaded onto the connecting ring 31. A connector 34, which is connected to the plug 32, is movably and fixedly connected to the fixing ring 33. A fixing head 35 is fixedly connected to the end of the fixing ring 33 away from the connector 34. The threaded locking design enables a quick and reliable connection between the cable head and the equipment, improving the efficiency and safety of on-site maintenance. The main manufacturing materials of the plug 4, plug 32, and connector 34 are beryllium copper. Beryllium copper has high strength and good elasticity, making it suitable for connectors with extremely high mechanical performance requirements. It also balances high conductivity and fatigue resistance, reducing contact surface deformation caused by repeated disassembly and assembly, and improving long-term reliability. Ethylene-vinyl acetate is the main processing raw material for the heat shrink sleeve 213. The EVA heat shrink tubing has good elasticity and flexibility, allowing it to better fit the cable, and also has a certain degree of waterproofing.

[0039] Other embodiments: The ethylene-vinyl acetate material used for the heat shrink tubing 213 can adopt other structures in the prior art, such as: polytetrafluoroethylene (PTFE) heat shrink tubing has excellent high-temperature resistance, up to 260℃, and also has excellent chemical stability and electrical insulation properties; polyvinyl chloride (PVC) heat shrink tubing is relatively inexpensive, has good insulation and wear resistance, but poor environmental performance, and is rarely used abroad. Its shrinkage temperature is relatively low, generally shrinking only above 98℃.

[0040] During operation, the connecting cable 214 is passed through the star-shaped dustproof ring 211 of the dust cover 210. The star-shaped dustproof ring 211 automatically fits according to the cable diameter. The heat shrink sleeve 213 wraps around the connection between the cable head 1 and the cable to achieve a seal. The sliding block 28 moves closer to the fixed post 23, causing the rotating ring 25 to rotate, which expands the arc plate 29 on the rotating plate 26 outward. Then, the connecting cable 214 is inserted into the inside of the arc plate 29. After that, the sliding block 28 is released, and the spring 24 provides continuous pressure to ensure a stable fixation. The arc plate 29 is tightly attached to the connecting cable 214. The plug 4 at the other end of the cable head 1 is inserted into the plug 32 of the quick connection assembly. The fixing ring 33 is rotated to lock the connector 34 and the plug 32, completing the quick connection between the cable and the equipment. The dust cover 210 is fixed to the cable head 1 by the screw ring 212 to further prevent dust from entering. Alternatively, the connector 34 can be removed from the connecting ring 31, and the cable head 1 of another set can be directly connected to one end of the connecting ring 31, so that the two sets of devices can be quickly connected together.

[0041] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations will be apparent to those skilled in the art without actually departing from the scope and spirit of the claims, such as variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.

[0042] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
