Description

Technical Field

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

[0002] In many fields such as power transmission, communication engineering, and industrial automation, cables serve as the key carriers of electrical energy and signal transmission, and their stability and reliability directly affect the safe operation of the entire system. Cable heads, as critical components connecting cables to equipment and between cables themselves, are of paramount importance in terms of performance.

[0003] Existing cable head reinforcement methods mostly involve simple wrapping, binding, or the use of ordinary fixing clamps. While these methods can provide some degree of fixation for the cable head, their ability to withstand dynamic loads such as vibration and tension in complex environments is limited. Therefore, there is a need for a cable head-reinforced cable. Utility Model Content

[0004] The purpose of this utility model is to provide a cable with a reinforced cable head, which strengthens the cable head by setting a reinforcement component to prevent the connection between the cable head and the cable body from loosening due to vibration and tension, thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable with reinforced cable head includes a cable body, and a reinforcement component is sleeved on the outside of the connector of the cable body;

[0007] The reinforcement assembly includes two sets of reinforcement shells fitted over the cable body. Each set of reinforcement shells has a rubber sleeve that fits against the outer wall of the cable body. Each set of rubber sleeves has anti-slip textures on the side that fits against the outer wall of the cable body. Several sets of springs are installed between each set of rubber sleeves and the reinforcement shells. The two ends of each set of springs are respectively connected to the outer wall of the corresponding rubber sleeve and the inner wall of the reinforcement shell.

[0008] Preferably, each set of spring sleeves is provided with a flexible corrugated tube, and the two ends of each set of corrugated tubes are respectively fixed to the inner wall of the reinforcing shell and the outer wall of the rubber sleeve.

[0009] Preferably, each set of reinforced shells has two sets of extension blocks symmetrically fixed to its sidewalls, and the corresponding extension blocks of the two sets of reinforced shells are connected by several sets of bolts.

[0010] Preferably, the front ends of both sets of reinforced shells are provided with threaded ends, and the external threads of the threaded ends are fitted with top covers that seal the two sets of reinforced shells.

[0011] Preferably, the inner wall of the top cover is provided with an annular insulating sealing gasket, and the inner wall of the insulating sealing gasket is provided with an arc-shaped groove that is adapted to the outer wall of the cable body.

[0012] Preferably, each set of reinforcing shells has a connecting shell at its rear end that fits against the outer wall of the cable body. The outer walls of the two sets of connecting shells are provided with annular grooves, and rubber rings for fixing the two sets of connecting shells are installed inside the annular grooves.

[0013] Preferably, the inner wall of the connecting shell is provided with an annular buffer protrusion, which is interference-fitted with the outer insulation layer of the cable body.

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

[0015] The elastic deformation of the spring effectively absorbs vibration energy, and when combined with the rubber sleeve, it significantly enhances the resistance to dynamic loads such as vibration and tension in complex environments, thus effectively preventing loosening or poor contact at the connection due to vibration. Simultaneously, the anti-slip texture of the rubber sleeve increases the friction of the contact surface, which, together with the elastic support of the spring, forms a composite fixing structure, further enhancing tensile strength. Through the coordinated cooperation of the various components of the reinforcement assembly, loosening between the cable body and the cable head due to vibration and tension can be effectively prevented, ensuring long-term stable cable use.

[0022] 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.

[0023] This utility model provides: a cable with a reinforced cable head, such as... Figures 1-5 As shown, the cable includes a cable body 1, and a reinforcing component 2 is fitted over the connector of the cable body 1. The cable body 1 is the core component for transmitting electrical energy or signals, and the reinforcing component 2 is fitted over its connector to provide protection at the connection between the cable body 1 and the connector.

[0024] The reinforcement component 2 includes two sets of reinforcement shells 201 fitted over the cable body 1. Each set of reinforcement shells 201 has a rubber sleeve 202 movably mounted inside, conforming to the outer wall of the cable body 1. Each rubber sleeve 202 has anti-slip textures 203 on one side conforming to the outer wall of the cable body 1. Several sets of springs 204 are installed between each set of rubber sleeves 202 and the reinforcement shell 201. The two ends of each spring 204 are respectively connected to the outer wall of the corresponding rubber sleeve 202 and the inner wall of the reinforcement shell 201. The reinforcement shell 201 is fitted over the connector of the cable body 1, providing a rigid mounting carrier for the internal rubber sleeves 202 and springs 204. Its inner wall conforms to the outer wall of the rubber sleeve 202, forming a cavity structure supporting the springs 204. The rubber sleeve 202 directly contacts the outer wall of the cable body 1, and the anti-slip textures 203 on its surface significantly increase the roughness of the contact surface with the cable's outer insulation layer, thereby directly preventing relative sliding between the rubber sleeve 202 and the cable body 1. Spring 204 is evenly distributed circumferentially between rubber sleeve 202 and reinforcing shell 201. When the cable is vibrated, spring 204 absorbs vibration energy through compression or stretching deformation, converting mechanical vibration into elastic potential energy of the spring. When subjected to tension, the elastic support force of spring 204 and the friction force of anti-slip texture form a resultant force to jointly resist axial tension.

[0025] The anti-slip texture 203 adopts a three-dimensional structure such as serrated, cross stripes, or raised dot array. By increasing the roughness of the contact surface between the rubber sleeve 202 and the outer wall of the cable body 1, the friction between the two is significantly increased. The texture direction forms a specific angle with the cable axis, which can resist axial tension and radial vibration at the same time. Under oblique load, it provides multi-directional anti-slip capability and effectively prevents relative sliding between the rubber sleeve and the cable.

[0026] Preferably, each set of springs 204 is fitted with a flexible bellows 205, with both ends of each bellows 205 fixed to the inner wall of the reinforcing shell 201 and the outer wall of the rubber sleeve 202, respectively. The flexible bellows 205, fitted over the springs 204, with their wavy structure, isolate external dust, liquids, and other contaminants without affecting the normal expansion and contraction of the springs 204, preventing corrosion or wear, ensuring the long-term stable elastic performance of the springs 204, and extending the service life of the reinforcing components.

[0027] The flexible corrugated tube 205 is made of silicone rubber or EPDM rubber with excellent weather resistance, possessing good flexibility and environmental adaptability. Its corrugated structure can freely deform with the extension and contraction of the spring 204, while forming a closed protective layer to isolate external dust, liquids and other contaminants, preventing the spring from being directly exposed to harsh environments, preventing corrosion or wear, and ensuring that the spring maintains stable elastic performance over a long period of time.

[0028] Furthermore, each set of reinforced shells 201 has two sets of extension blocks 206 symmetrically fixed to its sidewalls. The corresponding extension blocks 206 of the two sets of reinforced shells 201 are connected by several sets of bolts 207. The extension blocks 206 are symmetrically fixed to the sidewalls of the reinforced shells 201, and the two sets of reinforced shells 201 are locked into a complete ring structure by the bolts 207. This connection method facilitates the quick assembly and disassembly of the reinforced components 2, and improves the overall structural strength through rigid mechanical connection, preventing the reinforced shells 201 from loosening during vibration and causing internal component failure.

[0029] Furthermore, both sets of reinforced shells 201 have threaded ends at their front ends, and top covers 208 that seal the two sets of reinforced shells 201 are installed on the external threads of the threaded ends. The top covers 208 are connected to the front ends of the reinforced shells 201 through threads, thereby sealing the reinforced components and preventing external contaminants from entering the interior from both ends of the reinforced shells 201, thus protecting other internal components and preventing partial damage that would render the reinforced components 2 unusable.

[0030] It is worth noting that the inner wall of the top cover 208 is provided with an annular insulating sealing gasket 209, and the inner wall of the insulating sealing gasket 209 has an arc-shaped groove that fits the outer wall of the cable body 1. The insulating sealing gasket 209 on the inner side of the top cover 208 fits tightly with the outer wall of the cable body 1 through the arc-shaped groove, which not only isolates the metal reinforcing shell from the cable insulation layer to prevent leakage, but also forms a sealing structure through interference fit to prevent the intrusion of external pollutants such as water and dust, and protects internal components such as springs and rubber sleeves from environmental corrosion.

[0031] Specifically, each set of reinforcing shells 201 has a connecting shell 210 at its rear end that fits against the outer wall of the cable body 1. The outer walls of both sets of connecting shells 210 have annular grooves 211, and rubber rings 212 are installed inside the annular grooves 211 to fix the two sets of connecting shells 210. The connecting shells 210 are located at the rear end of the reinforcing shells 201, with their inner walls fitting against the cable body 1 and the annular grooves 211 on their outer walls embedding the rubber rings 212. The elastic fastening force of the rubber rings secures the outer insulation layer of the cable, preventing the reinforcing components from sliding along the cable axis and enhancing overall installation stability.

[0032] More specifically, the inner wall of the connecting shell 210 is provided with an annular buffer protrusion 213, which is interference-fitted with the outer insulation layer of the cable body 1. The buffer protrusion 213 is an annular elastic protrusion on the inner wall of the connecting shell 210, which absorbs low-frequency vibration energy through elastic deformation, while increasing the contact area to improve friction and reduce wear on the cable's outer insulation layer. When the cable is subjected to vibration or tension, the buffer protrusion 213 absorbs part of the energy through its own elastic deformation. At the same time, its protruding structure increases the contact area and frictional resistance between the connecting shell 210 and the outer insulation layer of the cable body 1, further preventing relative sliding between the reinforcing component 2 and the cable body 1.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
