Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an electric wire and cable with a protective function. Background Art

[0002] In industrial, construction and outdoor applications, wires and cables are often exposed to harsh conditions such as sunlight, rain, and chemical corrosion. When working, traditional wires and cables will generate a lot of heat in the wire core due to their high power. If the heat cannot be effectively discharged or dispersed, it may cause damage to the wire core.

[0003] In order to address the above problems, the Chinese patent with the existing announcement number CN219832243U proposes a wire and cable with a protective function. The device can effectively absorb and diffuse the heat generated by the wire core during operation through a heat conductive sheet, thereby avoiding damage to the wire core due to heat concentration or failure to effectively and timely dissipate heat during operation.

[0004] However, although the above-mentioned wire and cable with a protective function can guide heat to the outside through the heat conductive sheet to avoid damage to the wire core, the multiple battery cells of the wire and cable with a protective function are wrapped together by the sponge layer, and the protective block alone cannot effectively prevent the wire core from being crushed, which causes the cable to be easily damaged when being crushed. Therefore, the utility model provides a wire and cable with a protective function to meet the demand. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a wire and cable with a protective function.

[0006] The technical problem to be solved by the utility model is to provide a wire and cable with a protective function to solve the problem that the multiple battery cores of the existing wire and cable are wrapped together by a sponge layer, and the protective block alone cannot effectively prevent the wire cores from being crushed, thereby causing the cable to be easily damaged when being rolled.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] A wire and cable with a protective function, comprising:

[0009] The insulating layer has a plurality of triangular support frames arranged around its axis, and adjacent support frames are fixedly arranged in a close relationship. Through holes are provided in the support frames for the electric core to pass through, and the support frames are made of a hard material;

[0010] The outer layer is wrapped around the outside of the insulating layer, a sponge layer is arranged between the outer layer and the insulating layer, and the outer layer is made of PVC material.

[0011] Preferably, an insulating filler is filled between the interior of the support frame and the battery core.

[0012] Preferably, the insulating filler is cross-linked polyethylene.

[0013] Preferably, the support frame is made of aluminum alloy, and the support frame does not contact the battery cell.

[0014] Preferably, a shielding layer is fixedly connected between the insulating layer and the sponge layer for preventing external electromagnetic interference from affecting the internal conductor of the cable.

[0015] Preferably, a protective layer is fixedly connected between the sponge layer and the shielding layer.

[0016] Preferably, a metal mesh is fixedly connected between the protective layer and the sponge layer.

[0017] Preferably, a plurality of protrusions are arranged around the circumference of the outer layer, the protrusions are integrally formed with the outer layer, and a groove is defined on the outer layer between adjacent protrusions.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] In the above scheme, by providing a support frame and installing the battery cell in the through hole of the support frame, the stability of the triangular structure is utilized to improve the protection of the battery cell, avoid the battery cell from being crushed, and increase the service life of the cable.

[0020] In the above scheme, by providing a metal mesh and a protective layer, the protective layer increases the compressive and tensile strength of the cable and protects the internal structure from external physical damage. The metal mesh can further improve the protection and buffering performance of the interior of the cable.

[0021] In the above scheme, by setting the protrusions and grooves, when external pressure is applied to the cable, the pressure will press the protrusions, so that the pressure block will release the pressure through the grooves on both sides thereof, thereby dispersing the pressure and avoiding all pressure being applied to the battery core inside the cable.

[0029] like Figures 1 to 4 As shown, an embodiment of the utility model provides a kind of wire and cable with protective function, including an insulating layer 5, inside which a plurality of support frames 2 with triangular structures are arranged around its axis, adjacent support frames 2 are fitted and fixedly arranged, and a through hole 10 for allowing the electric core 1 to pass through is penetrated in the support frame 2, the support frame 2 is composed of a hard material, an outer coating 3 is wrapped around the outside of the insulating layer 5, a sponge layer 4 is provided between the outer coating 3 and the insulating layer 5, and the outer coating 3 is made of PVC material.

[0030] Specifically, by placing the battery cell along the through hole 10 inside the through hole 10 of the support frame 2, the stability of the triangular structure can improve the stability of the battery cell inside the insulating layer 5. At the same time, the cooperation of the outer layer 3 and the sponge layer 4 can enhance the protection of the battery cell in the insulating layer 5, avoid the battery cell from being crushed, and increase the service life of the cable. This solves the problem that the multiple battery cells of the existing wires and cables are wrapped together by the sponge layer 4, and the protective block alone cannot effectively prevent the wire core from being crushed, thereby causing the cable to be easily damaged when being crushed.

[0031] It should be noted that the material of the insulating layer 5 can be polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), ethylene propylene rubber (EPR), etc., and the specific material can be adjusted according to actual conditions.

[0032] like Figure 4 As shown, in the present embodiment, an insulating filler 11 is filled between the inside of the support frame 2 and the battery cell 1. The insulating filler 11 is cross-linked polyethylene. Specifically, the insulating filler 11 can prevent the battery cell from directly contacting the support frame 2, thereby preventing a short circuit between the battery cells. At the same time, the cross-linked polyethylene can withstand higher operating temperatures, has a larger current carrying capacity and good corrosion resistance, and is suitable for a variety of environmental conditions.

[0033] like Figures 1 to 4 As shown, in this embodiment, the support frame 2 is made of aluminum alloy, the support frame 2 is not in contact with the battery core 1, a shielding layer 6 is fixedly connected between the insulating layer 5 and the sponge layer 4 to prevent the influence of external electromagnetic interference on the internal conductor of the cable, a protective layer 7 is fixedly connected between the sponge layer 4 and the shielding layer 6, and a metal mesh 8 is fixedly connected between the protective layer 7 and the sponge layer 4. Specifically, the material of the support frame 2 can also be selected from copper alloy, cross-linked polyethylene, etc.; the shielding layer 6 in the cable is usually composed of semi-conductive materials, metal wires or belts, etc., which adopts a metal braided layer or a foil layer structure to effectively block external electromagnetic interference and maintain the stability of signal transmission. The shielding layer 6 is mainly set to uniformly conduct the conductive core and the insulating electric field, especially in medium and high voltage power cables of 6kV and above, a conductor shielding layer 6 and an insulating shielding layer 6 are generally set at the same time to ensure the normal operation of the cable and the stable transmission of the signal; further, the protective layer 7 is made of polyurethane or rubber material to increase the compressive and tensile strength of the cable and protect the internal structure from external physical damage; secondly, the metal mesh 8 can further improve the protection and buffering performance of the cable.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, in the present embodiment, a plurality of protrusions 12 are arranged around the circumference direction of the outer sheath 3, the protrusions 12 are integrally formed with the outer sheath 3, and a groove 9 is defined on the outer sheath 3 between adjacent protrusions 12. Specifically, when external pressure is applied to the cable, the pressure will compress the protrusions 12, so that the pressing block releases the pressure through the grooves 9 on both sides thereof, thereby dispersing the pressure and avoiding all pressure being applied to the battery core inside the cable. Secondly, the groove 9 is an arc-shaped structure.

[0035] Working principle:

[0036] By placing the battery cell along the through hole 10 inside the through hole 10 of the support frame 2, the stability of the triangular structure can improve the stability of the battery cell inside the insulating layer 5. At the same time, the shielding layer 6 in the cable can effectively block external electromagnetic interference and maintain the stability of signal transmission. The protective layer 7 and the metal mesh 8 can increase the compressive and tensile strength of the cable and protect the internal structure from external physical damage. The cooperation of the outer layer 3 and the sponge layer 4 can enhance the protection of the battery cell in the insulating layer 5. The protrusion 12 and the groove 9 can disperse the pressure to avoid all pressure being applied to the battery cell inside the cable, avoid the battery cell from being crushed, and improve the service life of the cable. This solves the problem that the multiple battery cells of the existing wires and cables are wrapped together by the sponge layer 4, and the protective block alone cannot effectively prevent the wire core from being crushed, which causes the cable to be easily damaged when being crushed.
