Description

Technical Field

[0001] This application relates to the field of anti-interference magnetic ring technology, specifically an anti-interference device for vehicle signal cables. Background Technology

[0002] Anti-interference magnetic rings, also known as EMI absorption magnetic rings, are used to suppress EMI interference on multi-strand cables, including noise and spike interference on power lines. They also have the ability to absorb electrostatic pulses, enabling electronic equipment to meet the corresponding international standards for electromagnetic compatibility (EMI / EMC) and electrostatic discharge. When in use, a multi-core cable or a bundle of multi-strand cables can be threaded through it.

[0003] Chinese utility model patent CN 220342734 U discloses an anti-interference magnetic ring device for electronic communication cables. It employs a primary support assembly and a secondary support assembly, both equipped with anti-slip layers to protect the connection between the primary and secondary support assemblies and the communication cable. Connecting sleeves are positioned between two sets of transverse retaining rings, each fitted with a rubber sleeve. These rubber sleeves are then fitted onto the communication cable to strengthen the connection and improve stability. However, in practical use, the fixed dimensions of the primary and secondary support assemblies prevent flexibility in adjusting for varying cable thickness and quantity. To wrap more cables, different equipment sizes must be used, resulting in limited adjustability.

[0004] Therefore, this application provides an anti-interference device for vehicle signal cables to solve the above problems. Utility Model Content

[0005] This application provides an anti-interference device for vehicle signal cables, which aims to solve the problems mentioned in the background art, such as the poor adjustment flexibility of existing anti-interference magnetic ring devices.

[0006] To achieve the above objectives, this application provides the following technical solution: an anti-interference device for vehicle signal cables, comprising a wrapping portion and a magnet portion disposed within the wrapping portion.

[0007] Both the wrapping part and the magnet part are arranged in a sheet-like shape;

[0008] The magnet part is made of a flexible material;

[0009] The outer wall of the wrapping section is fixedly equipped with Velcro A and Velcro B, both of which are strip-shaped and are bonded together. In use, the wrapping section acts as a support, wrapping the magnet around one or more signal cables. Then, the wrapping section is tightened, attaching Velcro A to Velcro B, thus tightening the wrapping section and firmly securing the magnet to the cable. This allows for flexible adjustment of the tightness according to the size and quantity of the cable, making operation convenient. The tightened wrapping section presses the magnet firmly against the cable, preventing slippage and ensuring stable and reliable installation.

[0010] Preferably, to ensure anti-interference effect, the magnet part is specifically a ferrite magnetic sheet, and the magnet part is disposed in close contact with the inner wall of the wrapping part to effectively suppress interference signals, thereby ensuring anti-interference performance.

[0011] Preferably, in order to protect the magnet part, the wrapping part is specifically a rubber sheet, and an adhesive layer is coated between the wrapping part and the magnet part. The wrapping part and the magnet part are bonded to each other through the adhesive layer, which improves wear resistance and impact resistance, and extends the service life of the equipment.

[0012] Preferably, for heat dissipation, a plurality of ventilation holes are provided on the outer wall of the wrapping part. The plurality of ventilation holes are evenly distributed on the wrapping part. The ventilation holes penetrate the outer wall surface of the wrapping part and are fitted to the outer wall of the magnet part to reduce high heat damage and improve safety.

[0013] Preferably, in order to ensure heat dissipation, the hook and loop fastener B side is provided with a plurality of hook and loop fastener B sides, which are evenly distributed on the outer side wall of the wrapping part, so that the ventilation holes on the wrapping part can dissipate heat normally and ensure heat dissipation efficiency.

[0014] This anti-interference device uses the wrapping part as a support, wrapping the magnet part around one or more strands of signal cable, then tightening the wrapping part, and attaching the Velcro A side of the wrapping part to the Velcro B side, thereby tightening the wrapping part and tightly binding the magnet part to the cable. This allows for easy adjustment of the tightness according to the size and quantity of the cable harness, making the adjustment flexible and the operation convenient. After tightening, the wrapping part compresses the magnet part tightly to the cable and is not easy to slip, ensuring stable and reliable installation.

[0015] This anti-interference device allows the heat generated when passing through the magnet section's protective circuit to dissipate through the vent holes, ensuring that the equipment has a certain degree of heat dissipation, reducing high-temperature damage, and improving safety.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides an anti-interference device for vehicle signal cables, such as... Figs. 1-3 As shown, the anti-interference device includes a wrapping part 1 and a magnet part 2 disposed within the wrapping part 1.

[0024] Both the wrapping part 1 and the magnet part 2 are provided in a sheet-like shape;

[0025] The magnet part 2 is made of flexible material;

[0026] Hook and loop fastener A side 11 and hook and loop fastener B side 12 are fixedly installed on the outer wall of the wrapping part 1. Both hook and loop fastener A side 11 and hook and loop fastener B side 12 are strip-shaped and are bonded to each other.

[0027] In use, the wrapping part 1 serves as a support, and the magnet part 2 is wrapped around one or more strands of signal cable. Then, the wrapping part 1 is tightened, and the Velcro A side 11 on the wrapping part 1 is attached to the Velcro B side 12, thereby tightening the wrapping part 1 and tightly binding the magnet part 2 to the cable. This allows for easy adjustment of the tightness according to the size and quantity of the cable harness, making the adjustment flexible and the operation convenient. After tightening, the wrapping part 1 compresses the magnet part 2 tightly onto the cable, preventing it from slipping easily, ensuring stable and reliable installation.

[0028] Specifically, the magnet part 2 is a ferrite magnetic sheet, and the magnet part 2 is set to fit against the inner wall of the wrapping part 1.

[0029] In use, ferrite magnetic sheets utilize their high permeability to cause a sharp increase in impedance at high frequencies, converting interference signals into heat energy and thus suppressing electromagnetic interference. At low frequencies, the impedance of the ferrite ring is relatively low, allowing signals to pass through smoothly; while at high frequencies, the impedance increases significantly, effectively suppressing interference signals and ensuring anti-interference performance.

[0030] More specifically, the wrapping part 1 is a rubber sheet, and an adhesive layer 13 is coated between the wrapping part 1 and the magnet part 2, and the wrapping part 1 and the magnet part 2 are bonded to each other through the adhesive layer 13.

[0031] When in use, the rubber sheet-made wrapping part 1 is flexible and easy to adjust while protecting the magnet part 2, improving wear resistance and impact resistance, and extending the service life of the equipment.

[0032] It is understandable that the adhesive layer 13 is used to fix and bond the wrapping part 1 and the magnet part 2, which is convenient, quick and easy to process.

[0033] Example 2

[0034] Unlike Embodiment 1, the ferrite sheet utilizes its high permeability to rapidly increase impedance at high frequencies, converting interference signals into heat energy to suppress electromagnetic interference. However, intense heat generation can affect the safety and stability of the circuit. Therefore, a number of vent holes 14 are provided on the outer wall of the wrapping part 1. The vent holes 14 are evenly distributed on the wrapping part 1, penetrating the outer wall of the wrapping part 1 and fitting snugly against the outer wall of the magnet part 2.

[0035] When in use, the heat generated when passing through the protective circuit of the magnet part 2 can be dissipated through the vent 14, ensuring that the equipment has a certain heat dissipation, reducing high heat damage and improving safety.

[0036] Specifically, there are several hook and loop fasteners B-side 12, which are evenly distributed on the outer wall of the wrapping part 1.

[0037] It is understandable that the strip-shaped hook and loop fastener B side 12 is evenly distributed on the wrapping part 1 to ensure a firm bond when it is attached to the hook and loop fastener A side 11. At the same time, the dispersed design of the hook and loop fastener B side 12 will not cause large-area obstruction of the wrapping part 1, so that the ventilation holes 14 on the wrapping part 1 can dissipate heat normally and ensure heat dissipation efficiency.

[0038] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
