Description

Technical Field

[0001] This utility model relates to flexible cables, conductors, or flexible wires, such as in the field of traction cable technology, specifically a sheathed wire module. Background Technology

[0002] Sheathed wires, as a common type of electrical wire, play an important role in home decoration and electrical appliance connections. Sheathed wires refer to single-core or multi-core wires with a sheath layer, usually composed of three or two cores. This design provides additional safety and protection. The structure of sheathed wires includes an inner insulated conductor and an outer protective layer. Common conductor materials include copper and aluminum.

[0003] During home renovations, the sheathed cables used are usually embedded inside the walls. However, the sheathed cables for electrical connections are typically exposed. These exposed cables can be pulled as needed, causing them to bend. When bending, one side of the cable is compressed while the other side is stretched. If the bending is too extreme, it can exceed the cable's tolerance, leading to damage to the bent portion. Furthermore, some of the exposed cable may be on the ground, where it can be stepped on unnoticed, causing wear and tear and shortening the cable's lifespan. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sheathed wire module that enhances the bending resistance and wear resistance of the sheathed wire, thereby effectively reducing the damage caused by bending and preventing the sheathed wire from being easily damaged by compression and wear, thus improving the service life of the sheathed wire.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a sheathed wire module, comprising three copper cores and a protective sleeve, wherein the outer surface of each of the three copper cores is covered with a first rubber sleeve, and the three copper cores are all disposed inside the protective sleeve;

[0008] The outer surfaces of the three copper cores and the inner wall of the protective sleeve are filled with a filler core, which is made of rubber.

[0009] The outer surface of the protective cover is fixedly fitted with a metal armor sleeve, and the outer surface of the metal armor sleeve is fixedly fitted with a wear-resistant sleeve.

[0010] The outer surface of the wear-resistant sleeve has several annular grooves, which are arranged in a left-right configuration.

[0011] Preferably, the protective sleeve includes a second rubber sleeve that wraps around the outer surface of the three copper cores;

[0012] An anti-interference sleeve is fixedly fitted onto the outer surface of the second rubber sleeve. The anti-interference sleeve is composed of copper wire winding and copper strip wrapping.

[0013] Preferably, a heat dissipation sleeve is fixedly fitted onto the outer surface of the anti-interference sleeve, and the heat dissipation sleeve is made of polyvinyl chloride material.

[0014] Preferably, a waterproof sleeve is fixedly fitted onto the outer surface of the heat dissipation sleeve, and the waterproof sleeve is made of ethylene propylene rubber.

[0015] Preferably, a heat-absorbing sleeve is fixedly fitted onto the outer surface of the waterproof sleeve, and the heat-absorbing sleeve is made of a low-smoke halogen-free material.

[0016] Preferably, a fireproof sleeve is fixedly fitted onto the outer surface of the heat-absorbing sleeve, and the fireproof sleeve is made of refractory material.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a sheathed wire module, which has the following beneficial effects:

[0019] (1) When the sheathed wire is pulled, the sheathed wire will bend. When the wear-resistant sleeve bends, the annular groove will deform along with the bending. The presence of the annular groove improves the flexibility of the sheathed wire when bending, reduces the damage caused by excessive stretching or compression, and thus improves the bending resistance of the sheathed wire. At the same time, the metal armor sleeve improves the mechanical strength of the sheathed wire, which in turn improves the wear resistance of the sheathed wire. In this way, the bending resistance and wear resistance of the sheathed wire can be improved, thereby effectively reducing the damage caused by bending to the sheathed wire. It also avoids the situation where the sheathed wire is easily damaged by compression and wear, and improves the service life of the sheathed wire.

[0020] (2) In this sheathed cable module, the first rubber sleeve, the filling core and the second rubber sleeve can protect the internal copper core. The anti-interference sleeve can protect the cable and the connected equipment from electromagnetic interference. The heat generated by the copper core during operation can be dissipated through the heat dissipation sleeve. The waterproof sleeve can prevent external moisture and humidity from entering the interior of the sheathed cable. The heat-absorbing sleeve can absorb heat and release water vapor when heated. In this process, heat absorption can play a cooling role. At the same time, the evaporation of water vapor can continuously carry away heat and maintain the fire resistance of the cable. The fireproof sleeve protects the cable from the impact of fire and prevents flames from entering the interior of the cable. It ensures that the cable can maintain normal electrical and mechanical properties in high-temperature environments, thereby reducing the impact of various external factors on the sheathed cable and ensuring that the sheathed cable can work normally.

[0025] 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.

[0026] Please see Figures 1 to 3 This utility model provides a new technical solution: a sheathed wire module, including three copper cores 1 and a protective sleeve 3. The outer surface of each of the three copper cores 1 is wrapped with a first rubber sleeve 2. The three copper cores 1 are all located inside the protective sleeve 3. A filler core 4 made of rubber is filled between the outer surface of the three copper cores 1 and the inner wall of the protective sleeve 3. A metal armor sleeve 5 is fixedly sleeved on the outer surface of the protective sleeve 3. A wear-resistant sleeve 6 is fixedly sleeved on the outer surface of the metal armor sleeve 5. Several annular grooves 7 are opened on the outer surface of the wear-resistant sleeve 6, and the several annular grooves 7 are arranged in a left-right arrangement.

[0027] Furthermore, the protective sleeve 3 includes a second rubber sleeve 8, which wraps around the outer surface of the three copper cores 1. An anti-interference sleeve 9 is fixedly fitted onto the outer surface of the second rubber sleeve 8. The anti-interference sleeve 9 is composed of copper wire winding and copper strip wrapping. A heat dissipation sleeve 10 is fixedly fitted onto the outer surface of the anti-interference sleeve 9. The heat dissipation sleeve 10 is made of polyvinyl chloride material. A waterproof sleeve 11 is fixedly fitted onto the outer surface of the heat dissipation sleeve 10. The waterproof sleeve 11 is made of ethylene propylene rubber. A heat-absorbing sleeve 12 is fixedly fitted onto the outer surface of the waterproof sleeve 11. The heat-absorbing sleeve 12 is made of low-smoke halogen-free material. A fireproof sleeve 13 is fixedly fitted onto the outer surface of the heat-absorbing sleeve 12. The fireproof sleeve 13 is made of fire-resistant material.

[0028] When in use, the sheathed wire bends when pulled. As the wear-resistant sleeve 6 bends, the annular groove 7 deforms accordingly. The presence of the annular groove 7 improves the flexibility of the sheathed wire during bending, reducing damage caused by excessive stretching or compression, thus enhancing its bending resistance. Simultaneously, the metal armor sleeve 5 increases the mechanical strength of the sheathed wire, further improving its wear resistance. In this way, the bending and wear resistance of the sheathed wire are enhanced, effectively reducing damage caused by bending and preventing damage from compression and wear, thereby extending its service life.

[0029] Furthermore, the first rubber sleeve 2, the filler core 4, and the second rubber sleeve 8 can all protect the internal copper core 1. The anti-interference sleeve 9 can protect the cable and connected equipment from electromagnetic interference. The heat generated by the copper core 1 during operation can be dissipated through the heat dissipation sleeve 10. The waterproof sleeve 11 can prevent external moisture and humidity from penetrating the interior of the sheathed wire. The heat-absorbing sleeve 12 can absorb heat and release water vapor when heated. In this process, heat absorption can play a cooling role. At the same time, the evaporation of water vapor can continuously remove heat and maintain the fire resistance of the cable. The fireproof sleeve 13 protects the cable from the impact of fire and prevents flames from entering the interior of the cable. It ensures that the cable can maintain normal electrical and mechanical properties in high-temperature environments, thereby reducing the impact of various external factors on the sheathed wire and ensuring that the sheathed wire can work normally.

[0030] Working principle: When in use, the sheathed line bends when pulled. As the wear-resistant sleeve 6 bends, the annular groove 7 deforms along with the bending. The presence of the annular groove 7 improves the flexibility of the sheathed line when bending, reduces damage caused by excessive stretching or compression, and thus improves the bending resistance of the sheathed line. At the same time, the metal armor sleeve 5 improves the mechanical strength of the sheathed line, which in turn improves its wear resistance.

[0031] Furthermore, the first rubber sleeve 2, the filler core 4, and the second rubber sleeve 8 can all protect the internal copper core 1. The anti-interference sleeve 9 can protect the cable and connected equipment from electromagnetic interference. The heat generated by the copper core 1 during operation can be dissipated through the heat dissipation sleeve 10. The waterproof sleeve 11 can prevent external moisture and humidity from penetrating the interior of the sheathed cable. The heat-absorbing sleeve 12 can absorb heat and release water vapor when heated. In this process, heat absorption can play a cooling role. At the same time, the evaporation of water vapor can continuously remove heat and maintain the fire resistance of the cable. The fireproof sleeve 13 protects the cable from the impact of fire, prevents flames from entering the interior of the cable, and ensures that the cable can maintain normal electrical and mechanical properties in high-temperature environments.

[0032] 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.
