[0028] The utility model provides Figure 1 A low-voltage cross-linked irradiated cable is shown, comprising a core 1, and further comprising:
[0029] A fixing mechanism 2, arranged outside the plurality of wire cores 1, for installing and fixing the wire cores 1;
[0030] The protection mechanism 3 is arranged outside the fixing mechanism 2 and is used to protect the internal structure of the cable.
[0031] In order to keep the core 1 stable inside the cable, Figure 2 and Figure 3 As shown, the fixing mechanism 2 includes a mounting block 201, and the outer wall of the mounting block 201 is provided with three placement grooves 203, the inner walls of the three placement grooves 203 are movably connected to the outer walls of the three wire cores 1 respectively, and the inner walls of the three placement grooves 203 are provided with a pressing plate 205 on the side away from the wire core 1. The placement grooves 203 can install and fix the wire core 1, and the pressing plate 205 can press and limit the three wire cores 1 so that the wire core 1 remains stable inside the placement grooves 203.
[0032] In order to make the cable adapt to more environments, such as Figure 2 and Figure 4 As shown, the protective mechanism 3 includes a reinforcing net 301, which is fixedly sleeved on the outer side of the mounting block 201, a sealing layer 302 is fixedly sleeved on the outer side of the reinforcing net 301, a waterproof layer 303 is fixedly sleeved on the outer side of the sealing layer 302, and a wear-resistant layer 304 is fixedly sleeved on the outer side of the waterproof layer 303. The reinforcing net 301 can reinforce the internal structure of the cable, making the internal structure of the cable more solid and making the cable have good ductility. At the same time, the waterproof layer 303 and the wear-resistant layer 304 can protect the wire core 1, and can extend the service life of the cable.
[0033] In order to make the internal structure of the cable more solid, Figure 2 and Figure 3 As shown, the fixing mechanism 2 includes a reinforcing rib 202, and three reinforcing ribs 202 are provided. The three reinforcing ribs 202 are inserted into the inner wall of the mounting block 201 in a ring shape with equal intervals. The reinforcing ribs 202 are arranged in the gap between two adjacent placement grooves 203. The reinforcing ribs 202 can reinforce the structure of the mounting block 201, so that the three wire cores 1 can remain stable inside the mounting block 201.
[0034] In order to ensure that the pressing plate 205 can be stably fixed to the inside of the mounting block 201 so that it can stably press and limit the wire core 1, as shown in FIG. Figure 2 and Figure 3 As shown, the fixing mechanism 2 includes a limiting groove 204, and the limiting groove 204 is provided with three groups. The three groups of limiting grooves 204 are respectively opened at the top of both sides of the inner walls of the three placement grooves 203, and the outer walls of both sides of the pressure plate 205 are fixedly installed with limiting blocks 206. The outer walls of the limiting blocks 206 are movably connected to the inner walls of the adjacent limiting grooves 204. The left-view vertical section of the placement groove 203 is set as a U-shaped structure, and the left-view vertical sections of the limiting groove 204 and the limiting blocks 206 are both set as rectangular structures. The connection between the limiting groove 204 and the limiting blocks 206 enables the pressure plate 205 to stably press and limit the wire core 1.
[0035] In order to make the cable have good anti-slip properties, such as Figure 2 As shown, the protective mechanism 3 includes an anti-skid protrusion 305, which is fixedly installed on the outside of the wear-resistant layer 304. The left-view vertical section of the anti-skid protrusion 305 is arranged as a fan-shaped structure. The arrangement of the anti-skid protrusion 305 enables the cable to have good anti-skid performance, which can facilitate the staff to pull and install the cable.
[0036] The specific implementation method is as follows: during the production process of the cable, a plurality of reinforcing ribs 202 are inserted into the inside of the installation block 201, and then three cores 1 are placed into the inside of the three placement grooves 203, and then the pressing plate 205 is installed to the outside of the placement groove 203, so that the limiting blocks 206 on both sides thereof can be inserted into the inside of the adjacent limiting grooves 204, so that the pressing plate 205 can stably press and limit the core 1, and then the reinforcing net 301 is fixedly sleeved to the outside of the installation block 201 and the pressing plate 205, and then the sealing layer 302 is fixedly sleeved to the outside of the reinforcing net 301 by injection molding, and then the waterproof layer 303 is fixedly sleeved to the outside of the sealing layer 302, and then the waterproof layer 303 is fixedly sleeved to the outside of the sealing layer 302, and then the waterproof layer 303 is fixedly sleeved to the outside of the waterproof layer 303. The wear layer 304 is fixedly sleeved onto the outside of the waterproof layer 303, and a plurality of anti-slip protrusions 305 are formed on the outside of the wear-resistant layer 304 by casting, and the internal structure of the cable is further stabilized by the arrangement of the reinforcing ribs 202 and the reinforcing net 301. The arrangement of the sealing layer 302 enables the reinforcing net 301 to stably seal the fixing mechanism 2, and the waterproof layer 303 enables the cable to have a good waterproof effect, and the arrangement of the wear-resistant layer 304 enables the cable to have a good wear-resistant effect, thereby extending the service life of the cable. This embodiment specifically solves the problem in the prior art that the connection between the internal cable core and the outer rubber structure of the cable is easily loose, which affects the service life of the cable.
[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
