Abstract
Description
Technical Field
[0001] The utility model belongs to the field of new energy vehicles, and in particular relates to a shielding ring for an automobile high-voltage wire harness. Background Art
[0002] Electromagnetic radiation interference is an inevitable problem in power communications, and it also exists in the field of new energy vehicles. To solve this problem, high-voltage cables usually have shielding rings outside the cable shielding layer to shield the interference of electromagnetic radiation. Most of the shielding rings currently on the market are one-piece structures, and the side walls of the shielding rings are integrally formed with circumferentially arranged overlapping springs, which are overlapped with the conductive components through the overlapping springs. The disadvantages are: 1. A cable of a certain specification needs to be equipped with a shielding ring of the corresponding specification, which has the disadvantage of poor adaptability; 2. The adaptability between the overlapping springs on the shielding ring and the conductive components is also poor. Usually, a conductive component of a certain specification requires customized adaptive overlapping springs. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a chain-belt type metal shielding ring and a cable with good adaptability.
[0004] In order to solve the above problems, the technical solution adopted by the present invention is as follows: a chain belt body, wherein a group of overlapping spring plates arranged at intervals are integrally formed on the chain belt body, and a connector is provided at one end thereof, and the connector is provided with a socket adapted to the chain belt body.
[0005] The chain-belt type metal shielding ring is characterized in that the overlapping spring piece is in the shape of an elongated strip and forms a U-shaped gap between the overlapping spring piece and the chain-belt body.
[0006] The chain-belt type metal shielding ring is characterized in that there are 8 overlapping spring pieces.
[0007] A cable comprises a cable body, wherein the outer surface of the cable body is provided with a cable shielding layer, and is characterized in that the cable shielding layer of the cable body is provided with the chain-belt type metal shielding ring described in any one of the above items outside.
[0008] The advantages of the chain-belt type metal shielding ring and cable of the present invention are as follows: 1. By adjusting the length of the chain-belt body, it can be adapted to the outer diameters of cables of different specifications; 2. By bending and overlapping the spring sheets, it can be adapted to conductive components of different specifications.
[0009] The present invention will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a structural diagram of the chain-belt type metal shielding ring of the utility model;
[0011] Figure 2It is a structural schematic diagram of the utility model cable. DETAILED DESCRIPTION Embodiment 1:
[0012] Reference Figure 1 As shown, the chain-type metal shielding ring of the present invention includes a conductive chain-belt body 1, which is usually made of stainless steel and has a thickness of 0.5 mm, a width of 8 mm, and a length of 100 mm. A group of overlapping spring pieces 2 arranged at intervals are integrally formed on the chain-belt body 1, and a connector 3 is provided at one end thereof, and a socket 4 adapted to the chain-belt body 1 is provided on the connector 3. Crimping edges 5 are left on both sides of the chain-belt body 1. The length of the overlapping spring piece 2 is 9 mm and the width is 8 mm. The method of use is similar to a cable tie. Insert the end of the chain-belt body 1 into its socket 4, then tighten it to the outside of the shielding layer of the cable, and finally crimp the crimping edge 5 of the chain-belt body 1 with a crimping tool.
[0013] Preferably, the overlapping spring piece 2 is elongated, and a U-shaped gap 6 is formed between the overlapping spring piece 2 and the chain belt body 1. The gap distance of the U-shaped gap 6 is preferably 0.5 mm. With this structure, when the chain belt body 1 is wrapped around the shielding layer of the cable, the overlapping spring piece 2 can automatically extend to facilitate contact or bending.
[0014] Preferably, the ideal number of the overlapping spring pieces 2 is 8, so as to adapt to the main specifications of cables currently on the market. Example 2:
[0015] Reference Figure 2 As shown, a cable according to the present invention includes a cable body 7, the outer surface of which is provided with a cable shielding layer 8. The cable shielding layer 8 of the cable body 7 is provided with the chain-type metal shielding ring a described in Example 1. The specific installation method is similar to that of a cable tie. The end of the chain-type metal shielding ring 1 is inserted into the socket 4 of the chain-type metal shielding ring 8 and then tightened to the outer surface of the cable shielding layer. Finally, the crimping edge 5 of the chain-type metal shielding ring 1 is crimped and fixed using a crimping tool. If the cable body 7 is too long, the excess portion can be cut off.
[0016] The above does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
