Description

Technical Field

[0001] The utility model relates to the technical field of shielding belts, in particular to an electric power shielding belt. Background Art

[0002] With the continuous development of my country's industry, my country has now fully entered the era of electrification, and the use of power cables is increasing. The main component of the conductor of the cable is copper, accounting for about 70% of the total copper used. However, my country's copper resources are very scarce. With the depletion of China's copper resources, 80% of China's copper needs to be imported, and the dependence is high. With the continuous rise in copper prices, replacing copper with aluminum is an inevitable trend in the development of wires and cables.

[0003] Currently, when producing cables, it is necessary to cover the outer surface of the cable core with a layer of shielding tape to prevent static electricity from being generated when transmitting current. At the same time, the shielding tape can also constrain the multiple strands of cells, making the multiple strands of cells more compact. However, after covering with the shielding tape, it is easy for the cells to slip between the cells and the insulating protective sleeve, and it is impossible to fill the threaded gaps formed after the multiple strands of cells are wound and connected, resulting in relative sliding between the cells and the insulating sleeve. Utility Model Content

[0004] In order to solve the problems in the prior art, the utility model provides an electric power shielding belt.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0006] An electric power shielding tape comprises an elastic guide rib, wherein a plurality of battery cell bodies are arranged equidistantly along the circumferential direction on the outer surface of the elastic guide rib, wherein the plurality of battery cell bodies are all spiral-shaped, a shielding tape body is arranged between the outer surfaces of the plurality of battery cell bodies, an insulating protective sleeve is arranged on the outer side of the shielding tape body, and a plurality of thread grooves are opened on the inner wall of the insulating protective sleeve at equal intervals along the circumferential direction.

[0007] Optionally, the shielding tape body includes a foam rubber pad, the bottom of which is in contact with the outer surfaces of the plurality of battery cell bodies and is filled into the thread-shaped gaps between the plurality of battery cell bodies.

[0008] Optionally, a buffer layer is provided on the top of the foam rubber pad, and an elastic net is filled between the buffer layer and the foam rubber pad.

[0009] Optionally, a bridging layer is provided on the top of the buffer layer, and a high temperature resistant and fireproof layer is provided on the top of the bridging layer.

[0010] Optionally, a plurality of anti-slip strips are provided on the top of the high temperature resistant and fireproof layer, and the plurality of anti-slip strips are correspondingly attached to the inner wall of the insulating protective sleeve.

[0011] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0012] 1. In the utility model, when using the device, firstly, a plurality of battery cell bodies are spirally wound on the outer surface of the elastic guide ribs, and the plurality of battery cell bodies are supported by the elastic guide ribs. Then, the shielding belt body is wrapped between the outer surfaces of the plurality of battery cell bodies so that the plurality of battery cell bodies can be restrained and tightened. At the same time, an insulating protective sleeve is arranged on the outer side of the shielding belt body to provide insulation protection for the battery cell body as a whole.

[0013] 2. In the utility model, a foam rubber pad is arranged at the bottom of the shielding tape body, so that when the battery body is covered, the foam rubber pad can be squeezed into the gap between the spirally wound battery bodies by the elastic deformation force of the foam rubber pad to fill it. At the same time, the elastic net is woven with rubber wire. The elastic net is arranged between the buffer layer and the foam rubber pad to buffer the connection between the foam rubber pad and the buffer layer, so as to prevent the connection between the foam rubber pad and the buffer layer from being torn when the foam rubber pad is elastically stretched and deformed.
