Description

Technical Field

[0001] This invention relates to the field of cable installation technology, and more specifically, to a shielded cable installation mechanism. Background Technology

[0002] Cables, as crucial carriers of power transmission and signal transmission, are widely used in various fields such as industrial production, construction engineering, and communication facilities. The installation quality of cables directly affects the operational stability and service life of the entire electrical system. In current technology, cable installation methods are relatively simple, typically using ordinary clips, straps, or simple brackets for fixation. While this installation method is convenient, it suffers from poor sealing and stability. During long-term use, cables are prone to loosening or displacement due to external environmental factors such as moisture, dust, and vibration, resulting in gaps between the cable and the interface. This not only affects the reliability of the electrical connection but may also cause safety hazards such as leakage and short circuits. Especially in applications requiring electromagnetic shielding, simple installation methods cannot provide effective shielding protection, making the cables susceptible to external electromagnetic interference or electromagnetic radiation, severely affecting the normal operation of equipment and the quality of signal transmission.

[0003] To address the aforementioned issues, some existing technologies employ complex installation structures to improve the sealing and stability of cable installations. These include combinations of multiple fasteners, sealing rings, and metal sheaths. While these methods improve the installation effect to some extent, they also make the installation process more cumbersome and complex, requiring various tools and auxiliary materials. The numerous installation steps and long installation time significantly increase the labor intensity and construction costs for workers. Furthermore, when cable maintenance, replacement, or adjustment is needed, disassembly is equally difficult, often requiring damage to the original structure. This hinders quick and convenient repeated disassembly and assembly, making later maintenance and management inconvenient and affecting overall performance and work efficiency. Therefore, there is an urgent need to design a shielded cable installation mechanism to solve these problems. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] Compared with existing technologies, this invention provides a shielded cable installation mechanism with the following advantages: This invention overcomes the problem of traditional cable installation requiring separate fixing of the cable body, shielding tube, and corrugated tube. It designs an integrated synchronous locking mechanism, achieving simultaneous locking and fixing of the cable, shielding tube, and corrugated tube in one operation. Through mechanical transmission design, the operator only needs to rotate the threaded sleeve as a single operating component to simultaneously drive the first inclined block to radially clamp the cable's outer wall, drive the second inclined block to lock the corrugated tube's outer wall, and drive the pressure plate to fix the shielding tube's outer wall via transmission chains such as the intermediate ring, inner ring, and push ring. The three locking actions are completed collaboratively in the same operation, eliminating the need for repeated operations. This integrated locking method not only simplifies the cable installation process by merging the three previously separate procedures into a single continuous action, improving construction efficiency and ease of operation, but also ensures that the triple protection measures of cable body protection, electromagnetic shielding protection, and mechanical protection are simultaneously in place, enhancing the installation quality and reliability of the cable system.

[0020] This invention utilizes a double-layered inclined mechanism—combining an inclined groove with a first inclined block and an inclined pressure ring with a second inclined block—along with the elastic compensation force provided by the first and second springs, to achieve a reasonable distribution and uniform application of locking force. When the operator rotates the threaded sleeve, the threaded pair converts the rotational motion into axial thrust. This thrust is transmitted to the intermediate ring through the thrust bearing, and then acts on the inner ring and the push ring, two actuators. The inclined groove in the inner ring generates a radial tightening force on multiple sets of first inclined blocks, causing them to uniformly grip the outer surface of the cable. Combined with the wrapping effect of the sealing ring, this achieves both reliable mechanical fixation and a good locking effect. The sealing effect prevents moisture and contaminants from entering. At the same time, the push ring pushes multiple sets of second inclined blocks to slide and tighten along the inner wall of the inclined pressure ring, forming a circumferentially distributed clamping force on the bellows. The pressure plate then applies stable pressure and fixation to the shielding tube. Due to the design of multiple sets of circumferentially distributed inclined blocks, the force borne by each set of inclined blocks is relatively small and evenly distributed, avoiding deformation and damage to the cable, shielding tube, or bellows caused by local stress concentration. The introduction of springs gives the locking mechanism a certain degree of elastic self-adaptive capability, which can compensate for slight differences in cable diameter and dimensional fluctuations caused by temperature changes, and always maintain a stable and reliable locking effect.

[0021] This invention considers operational safety during cable installation. In the initial state, the end of the sliding rod abuts against the side wall of the locking ring, locking the sliding rod. Even if the operator rotates the threaded sleeve, the sliding rod cannot move, and the entire locking mechanism will not activate. This forces the operator to first complete the threaded connection between the fixed cylinder and the external equipment. Only when the fixed cylinder is rotated into place, and the friction strip on the side wall of the locking ring comes into contact with the surface of the external equipment to generate sufficient friction, causing the locking ring to be obstructed and rotate relative to the fixed cylinder, can the sliding rod be inserted into the unlocking slot to complete the unlocking. Only then can the operator carry out subsequent installation and locking operations for cables, shielding pipes, and corrugated pipes. This mechanical interlock design avoids quality problems such as loose connections and fixing failures caused by improper installation sequence, improving the controllability and safety of the installation operation.

[0022] This invention also considers the convenience of later disassembly and maintenance, realizing the rapid disassembly and flexible replacement of cable systems. When it is necessary to inspect, replace or adjust the cable, the operator only needs to rotate the threaded sleeve in the reverse direction. The rebound force of the return spring will drive the slide rod to return to its original position, thereby pushing a series of components such as the slip ring and the inner ring to move in the reverse direction, releasing the clamping of the first inclined block on the cable, and releasing the locking of the second inclined block and the pressure plate on the corrugated pipe and the shielding pipe. The entire disassembly process is simple and quick to operate, reducing maintenance costs and downtime. This convenient disassembly and assembly feature makes the daily inspection, fault diagnosis and preventive maintenance of the cable system easy and efficient, which is conducive to timely detection and resolution of potential problems and extends the service life of the cable.

The side wall of the push ring 213 abuts against the side wall of the multiple sets of second inclined blocks 227.

[0039] In this invention, the locking mechanism enables synchronous locking of the cable 11, shielding tube 12, and corrugated tube 13. Figure 1 As shown, locking mechanisms are fitted at both ends of cable 11. Workers can choose how to use them based on actual needs. If cable 11 needs to connect both ends, two sets of locking mechanisms are used; if only one end needs to be connected, only one locking mechanism is needed. Specifically, taking the installation of one locking mechanism as an example, according to... Figure 5 As shown, the operator needs to pass the cable 11 through the fixed cylinder 21 to connect it to the external device. Then, the operator uses an external tool to insert it into the hexagonal groove 26 and rotate the fixed cylinder 21, causing one end of the fixed cylinder 21 to be threaded into the external device. At this time, the fixed cylinder 21 drives the locking mechanism to rotate synchronously until the multiple sets of friction strips 29 on the side wall of the locking ring 27 are in contact with the surface of the external device. As the fixed cylinder 21 continues to rotate, the friction between the friction strips 29 and the external device increases until the locking ring 27 is obstructed and can no longer rotate. At this point, the locking ring 27 overcomes the thrust of the multiple sets of balance springs 24 and engages with the fixed cylinder 21. When the relative rotation occurs, the balance spring 24 will also undergo corresponding deformation, that is, one side is stretched and the other side is compressed. In the initial state, the end of the slide rod 219 abuts against the side wall of the locking ring 27, and the locking ring 27 keeps the slide rod 219 in a locked state. When the locking ring 27 and the fixed cylinder 21 rotate relative to each other, multiple sets of slide rods 219 can be inserted into the unlocking slot 28, and the slide rod 219 is unlocked. After that, the staff needs to put the shielding tube 12 and the corrugated tube 13 onto the cable 11, so that one end of the shielding tube 12 corresponds to the position of multiple sets of pressure plates 229, and one end of the corrugated tube 13 corresponds to the position of the second inclined block 227.

[0040] Afterwards, the staff rotated the threaded sleeve 210 using external tools, causing it to move along the fixed cylinder 21 towards the external equipment. The threaded sleeve 210, through the thrust bearing 212, drove the intermediate ring 211 to move to the left simultaneously. The left end of the intermediate ring 211 pushed the slip ring 218, causing the inner ring 214 to move to the left. The slide rod 219 slid along the slide groove 25, and the end of the slide rod 219 inserted into the unlocking groove 28. The return spring 220 was compressed, and the inclined groove 217 in the inner ring 214 squeezed the multiple sets of first inclined blocks 224, causing the multiple sets of first inclined blocks 224 to gradually tighten. The first spring 225 deformed accordingly, and the multiple sets of first inclined blocks 224 gradually clamped the outer wall of the cable 11. Because the diameter of the multiple sets of adjusting grooves 226 in the first inclined blocks 224 was larger than the diameter of the locking rod 223, even if the locking rod 223 was embedded in the adjusting groove... The tightening of the first inclined block 224 will not be affected by the 226. At the same time, the intermediate ring 211 drives multiple sets of second inclined blocks 227 and the pressure plate 229 inside the second inclined block 227 to move to the left through the push ring 213. Because the locking rod 223 is inserted into the locking groove 22, the sealing ring 222 and the inclined pressure ring 221 are fixed. Therefore, the second inclined block 227 moves along the inner side wall of the inclined pressure ring 221 and gradually tightens. The second spring 228 also deforms accordingly. Multiple sets of second inclined blocks 227 clamp the outer side wall of the bellows 13, and the pressure plate 229 clamps the outer side wall of the shielding tube 12. The sealing ring 222 wraps around the outer side wall of the cable 11 to achieve a sealing effect. Thus, by rotating the threaded sleeve 210, the cable 11, the shielding tube 12 and the bellows 13 can be locked at the same time. The bellows 13 protects the cable 11.

[0041] When it is necessary to disassemble cable 11, the operator only needs to rotate the threaded sleeve 210 in the opposite direction. The return spring 220 rebounds and drives the slide rod 219 to reset, which in turn pushes the slip ring 218 to move the inner ring 214 to the right, releasing the squeezing pressure on the multiple sets of first inclined blocks 224. The slip ring 218 drives the push ring 213 to reset through the intermediate ring 211. The push ring 213 also stops squeezing the second inclined block 227, thereby releasing the tight contact between the first inclined block 224 and the surface of cable 11, and releasing the locking of the second inclined block 227 and the pressure plate 229 on the corrugated pipe 13 and the shielding pipe 12, so that cable 11 can be disassembled.
