[0017] 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.

[0018] Please see Figures 1-5 The present invention provides the following technical solution: A low-voltage multi-core cable includes a cable body 1; a protective mounting assembly 2 is provided on the outside of the cable body 1, the protective mounting assembly 2 includes an insulating protective layer 201, and a fireproof layer 202 is fixedly connected inside the insulating protective layer 201, and a water-blocking layer 203 is fixedly connected inside the fireproof layer 202; wherein, a support layer 204 is fixedly connected inside the water-blocking layer 203. Furthermore, the insulating protective layer 201, fireproof layer 202, water-blocking layer 203, and support layer 204 are well known in the prior art, therefore, the specific manufacturing materials will not be elaborated here, and a groove 205 is provided inside the support layer 204; wherein, fixing strips 206 are symmetrically fixed around the perimeter of the cable body 1, and connecting blocks 207 are fixedly connected to the front of the fixing strips 206 on the upper and lower sides, such as... Figure 1 , Figure 4 As shown, when it is necessary to install the cable body 1, the cable body 1 can be gradually inserted into the groove 205.

[0019] At the same time, it is necessary to ensure that the fixing strip 206 corresponds to the positioning groove 209. Then, the cable body 1 will be gradually wrapped by the insulation protection layer 201, the fireproof layer 202, the water-blocking layer 203 and the support layer 204. Before the cable body 1 is wrapped, the fixing strip 206 will move with the cable body 1. A locking block 208 is fixedly connected to one side of the connecting block 207, and the cable body 1 is compatible with the sliding groove 205.

[0020] The support layer 204 has symmetrically formed positioning grooves 209 inside, and the positioning grooves 209 are compatible with the fixing strips 206. Both the positioning grooves 209 and the fixing strips 206 are distributed in a ring shape. The support layer 204 also has symmetrically formed snap-fit ​​grooves 210 on its upper and lower surfaces. Figure 4 As shown, the connecting block 207 drives the locking block 208 to move, and then the locking block 208 locks into the inside of the locking slot 210. At the same time, the cable body 1 is completely covered, thus realizing the installation of the sleeve on the outside of the cable body 1, so that the cable can be put into use. When the cable body 1 is damaged and needs to be repaired, it is only necessary to pull the cable body 1 outward to detach the sheath, thus facilitating the repair and use of the cable body. Finally, since this application requires the entire protective sleeve to be removed when disassembling the cable body 1, for example, in scenarios such as computer rooms and data centers, the connection between network devices (such as switches and routers) needs to ensure high-speed and stable signal transmission. High-frequency signals or high-speed data are more sensitive to the length and curvature of the cable. Longer cables or curved installation methods may cause signal attenuation or distortion. Therefore, controlling the connection length of multi-core cables to within one meter and using straight installation can minimize signal loss and ensure the accuracy and reliability of data transmission. Therefore, this application is only convenient for repair when the wiring is short, and the locking block 208 and the locking slot 210 are mutually compatible.

[0021] One end of the cable body 1 is provided with a filling component 4. The filling component 4 includes a slider 401, and the slider 401 has an adapter groove 402 inside, which is adapted to the cable 1. The slider 401 also has symmetrically provided empty grooves 403 on its outside, which are adapted to the fixing strip 206. A positioning block 404 is symmetrically fixed on one side of the slider 401. Figures 3-5 As shown, after the cable body 1 is covered with protection, the slider 401 can be slid to the left, causing the slider 401 to slide. At the same time, the slider 401 will drive the positioning block 404 to move, and then the positioning block 404 will be locked into the interior of the limiting groove 405, so that the position of the slider 401 is fixed.

[0022] Then the slider 401 will block the gap between the fixing strip 206 and the support layer 204 to prevent dust from entering and affecting the life of the cable body 1. The support layer 204 has symmetrically opened limit grooves 405, and the positioning block 404 is compatible with the limit groove 405.

[0023] Working principle: Before using this type of low-voltage multi-core cable, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, when the cable body 1 needs to be installed, the cable body 1 can be gradually inserted into the sliding groove 205, while ensuring that the fixing strip 206 corresponds to the positioning groove 209. Then, the cable body 1 will be gradually wrapped by the insulation protective layer 201, the fireproof layer 202, the water-blocking layer 203, and the support layer 204. Before the cable body 1 is wrapped, the fixing strip 206 will move with the cable body 1, causing the fixing strip 206 to slide into the positioning groove 209, thus limiting the position as the cable body 1 slides in. Then, the fixing strip 206 will drive the connecting block 207 to move, and then the connecting block 207 will drive the locking block 208 to move. Then, the locking block 208 will lock into the locking groove 210. At the same time, the cable body 1 is completely covered, thus realizing the installation of the sleeve on the outside of the cable body 1, so that the cable can be put into use. When the cable body 1 is damaged and needs to be repaired, the sheath core can be detached simply by pulling the cable body 1 outward, thus facilitating the repair and use of the cable body.

[0024] After the cable body 1 is covered with protection, the slider 401 can be slid to the left, causing the slider 401 to slide. At the same time, the slider 401 will drive the positioning block 404 to move. Then the positioning block 404 will be locked into the interior of the limiting groove 405, fixing the position of the slider 401. Then the slider 401 will block the gap between the fixing strip 206 and the support layer 204 to prevent dust from entering and affecting the life of the cable body 1.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
