Description

[0001] Technical cable technology field

[0002] This utility model belongs to the field of cable technology, specifically, it relates to a motor cable. Background Technology

[0003] With the development of the power industry, the requirements for power supply reliability and power safety have been further improved. The heat dissipation of power equipment has also gradually attracted more and more attention. Wires and cables are the most commonly used power equipment. Wires and cables are mainly composed of single or multiple strands of conductors and insulation layers.

[0004] 1. Existing cable equipment does not yet have the capability to prevent cable cracks caused by high-frequency bending.

[0005] 2: Existing cable equipment uses electromagnetic interference shielding layers to form its resistance to external electromagnetic interference. However, in harsh noise environments, it is impossible to effectively solve electromagnetic interference, thus greatly reducing the working efficiency of the cable equipment.

[0006] To address the aforementioned problems, this application proposes a motor cable. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes a motor cable to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A motor cable includes a cable body; a shielding assembly located inside the cable body and outside a tensile component; a tensile component located inside the cable body and outside an insulation component; and an insulation component located inside the cable body and inside the shielding assembly. The shielding assembly includes a metal foil, a braided mesh, and a first slot. The metal foil is fixedly connected to the inner circumferential wall of the cable body, and the braided mesh is fixedly connected to the outer circumferential wall of the metal foil. The first slot is formed inside the metal foil.

[0010] Preferably, the tensile component includes a tensile frame, tension rings, a fixing tube, a connecting plate, a fixing groove, a tension groove, and a placement groove. The tensile frame is fixedly connected inside the circumference of the first groove. Multiple tension rings are fixedly connected to both sides of the tensile frame. A connecting plate is fixedly connected to the other side of the tensile frame. A fixing tube is fixedly connected to the other side of the connecting plate. A fixing groove is opened inside the fixing tube. Tension grooves are provided between the multiple tension rings. Multiple placement grooves are opened between the tensile frame and the tension rings.

[0011] Preferably, the insulating component includes an insulating block, a connecting hole, a fixing hole, and a limiting groove. Multiple insulating blocks are fixedly connected to the inner circumferential walls of the multiple placement grooves. The interior of each of the multiple insulating blocks is provided with a connecting hole, and a connecting hole is provided between the multiple insulating blocks. The interior of each of the multiple insulating blocks is provided with a fixing hole, and the inner sidewall of the multiple insulating blocks is fixedly connected with a limiting groove.

[0012] Preferably, a plurality of first cables are fixedly connected to the inner circumferential walls of the plurality of fixing holes, and the plurality of first cables are located around the second cable.

[0013] Preferably, a second cable is fixedly connected to the inner circumference of the limiting groove, and the second cable is fixedly connected to the connecting plate.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. When electromagnetic interference occurs within the cable, the metal foil and braided mesh on the cable body can provide sufficient noise protection in ordinary electromagnetic interference environments. In more severe noise environments, shielded cables combining braided mesh and metal foil must be used, which have stronger anti-electromagnetic interference capabilities, thus solving the problem of electromagnetic interference with the cable.

[0016] 2: When the cable is bent, by rotating the tension rings on the tension bracket, the tension grooves between the tension rings protect the first and second cables when the cable is bent, thus preventing cracks from forming inside the first and second cables. Attached Figure Description

The connecting plate 304 is fixedly connected to the other side of the tensile frame 301. The fixing tube 303 is fixedly connected to the other side of the connecting plate 304. A fixing groove 305 is opened inside the fixing tube 303. Tension grooves 306 are provided between the multiple tension rings 302. Multiple placement grooves 307 are opened between the tensile frame 301 and the tension rings 302. The design of the tensile frame 301, tension ring 302, fixing tube 303, connecting plate 304, fixing groove 305, tension groove 306 and placement groove 307 is used to buffer the cable through the tension ring 302 on the tensile frame 301, to fix the second cable 6 through the fixing tube 303, to connect the fixing tube 303 and the tensile frame 301 through the connecting plate 304, and to fix the first cable 5 through the placement groove 307.

[0027] It is worth noting that the insulating assembly 4 includes an insulating block 401, a connecting hole 402, a fixing hole 403, and a limiting groove 404. Multiple insulating blocks 401 are fixedly connected to the inner circumferential walls of multiple placement grooves 307.

[0028] It is worth noting that multiple first cables 5 are fixedly connected to the inner circumference of the multiple fixing holes 403, and the multiple first cables 5 are located around the second cable 6. The design of the fixing holes 403 is to place the first cables 5 inside the fixing holes 403, thereby achieving the effect of fixing the first cables 5.

The design of the limiting groove 404 is used to place the second cable 6 inside the limiting groove 404, thereby achieving the effect of fixing the second cable 6.

[0030] Working principle:

[0031] 1. When the staff performs a bending test on the cable, the cable body 1 is placed in the testing equipment. When the cable body 1 is bent, the tension rings 302 on the tension bracket 301 inside the cable body 1 first buffer the first cable 5 and the second cable 6 inside the cable body 1 when the cable body 1 is bent. Then, the tension grooves 306 between the multiple tension rings 302 relieve the bending tension generated by the tension rings 302, thereby protecting the first cable 5 and the second cable 6 from cracking when bending.

[0032] 2: When the staff conducts interference testing on the cable, the metal foil 201 inside the cable body 1 first reduces electromagnetic interference from the interference device, and then the braided mesh 202 inside the metal foil 201 strengthens the electromagnetic interference resistance of the cable body 1.
