Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically a double magnetic ring high anti-interference wire harness. Background Technology

[0002] In electronic devices and systems, wire harnesses, as carriers of signal transmission, are highly susceptible to external electromagnetic interference, such as strong electromagnetic fields generated by industrial equipment, communication base stations, lightning, or electromagnetic radiation generated by high-frequency devices, switching power supplies, motors, etc. in the equipment's own circuits. Interference signals can cause distortion, noise, or bit errors in the electrical signals transmitted by the wire harness, and in severe cases, may lead to abnormal equipment function, data transmission interruption, or even system failure.

[0003] Chinese Utility Model Patent Publication No. CN208539286U discloses an anti-interference integrated wire harness. The specification of this anti-interference integrated wire harness describes how the wire harness uses wire harness clips, through holes, and L-shaped clips to organize the connecting wires, enabling multiple sets of wire harness clips to be used simultaneously for guidance. The wire harness connectors, slots, bosses, sockets, and contact springs prevent the connecting wires from becoming tangled. The slots and bosses are matched, allowing multiple wire harness connectors to be connected together when a component has too many pins, facilitating installation. However, this anti-interference integrated wire harness lacks a multi-layer anti-interference structure, which can easily lead to interference during data transmission due to magnetic fields and other factors, thus hindering its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a double magnetic ring strong anti-interference wire harness, which can effectively solve the problem in the prior art that the lack of a multi-layer anti-interference structure makes it easy for the overall wire harness to cause interference during data transmission due to magnetic fields and other reasons during use, thus making it inconvenient for widespread use.

[0005] The technical solution adopted by this utility model is: a double magnetic ring strong anti-interference wire harness, including a first connector, a connecting wire harness and a second connector, wherein a sleeve assembly is provided at the outer edge of the connecting wire harness away from the first connector, and a magnetic ring assembly is provided at the outer edge of the connecting wire harness away from the sleeve assembly.

[0006] The sleeve assembly includes a sleeve body and a connecting sleeve. A first cavity is formed at the inner edge of the sleeve body, a buckle is formed at the inner edge of the first cavity, a rubber ring is fixedly installed at the inner edge of the sleeve body, and a second cavity is formed at the inner edge of the connecting sleeve.

[0007] Preferably, the first cavity and the second cavity are interconnected, and the cross-section of the second cavity has a funnel-shaped structure.

[0008] Through the above technical solution, the first cavity and the funnel-shaped second cavity are interconnected to form a gradually changing shielding channel. When interfered with, the external electromagnetic interference wave can be guided to reflect and attenuate in the cavity, so that the energy of the interference signal is weakened after multiple reflections in the cavity, thereby improving its anti-interference ability.

[0009] Preferably, the sleeve body is a thermoplastic elastomer, and the buckle is located on the inner wall of the first cavity and at the end away from the connecting sleeve.

[0010] The above technical solution uses a sleeve made of thermoplastic elastomer material, which has high flexibility and wear resistance. When the wire harness is bent, it is not easily damaged, making it easy to adapt to complex wiring scenarios. In addition, the design of the buckle, which is located on the inner wall of the first cavity, can tighten and compress the outer layer of the wire harness when the connecting wire harness passes through.

[0011] Preferably, the magnetic ring assembly includes a first magnetic ring sleeve and a second magnetic ring sleeve. A first through groove, a second through groove, and a third through groove are provided on the inner edges of both the first magnetic ring sleeve and the second magnetic ring sleeve. The connecting wire harness passes through the first through groove, the second through groove, and the third through groove and extends to its outer edge.

[0012] Through the above technical solution, the connection harness can pass through the first through slot, the second through slot and the third through slot by cooperation, and then the connection harness and the magnetic ring assembly can form two layers of winding, which can improve its anti-interference ability.

[0013] Preferably, a slot is provided on the outer edge of the first magnetic ring sleeve, and a rotating rod is fixedly installed on the other end of the first magnetic ring sleeve away from the slot. A second magnetic ring sleeve is rotatably installed on the first magnetic ring sleeve through the rotating rod. An extension plate and a locking element are fixedly installed on the end of the second magnetic ring sleeve near the slot. The locking element is snapped into the slot. The cross-section of the end of the locking element near the slot has an "oblique angle" shape. The locking element is a plastic elastic locking element.

[0014] Through the above technical solution, by cooperating with the rotating rod and the locking device, when connecting, the locking device can be inserted into the slot, which can realize the connection of the first magnetic ring sleeve and the second magnetic ring sleeve. The angled locking device can be easily inserted into the slot to lock the two together. The rotating rod can facilitate the opening and closing of the first magnetic ring sleeve and the second magnetic ring sleeve.

[0015] Preferably, at least two identical sleeve assemblies and magnetic ring assemblies are provided, with the two sleeve assemblies and magnetic ring assemblies located at the two ends of the connecting harness near the first connector and the second connector, respectively.

[0016] Through the above technical solution, the sleeve assembly and magnetic ring assembly are symmetrically arranged at both ends of the wire harness to form a multi-layer protection structure, which can simultaneously block the electromagnetic interference generated by the devices at both ends, so that the signal is not affected by the interference of the environment at both ends during transmission, thus improving the overall anti-interference performance.

[0017] Preferably, a label is provided at the outer edge of the connecting wire harness, and at least two identical labels are provided.

[0018] The above technical solution uses labels on the outer edge of the wire harness to identify its function, specifications, or routing, facilitating wiring differentiation during installation and subsequent maintenance and management. It also allows staff to quickly connect the wire harness body to its function and other data.

[0019] Compared with the prior art, this utility model provides a double magnetic ring strong anti-interference wire harness, which has the following beneficial effects:

[0020] 1. This double magnetic ring strong anti-interference wire harness has a first cavity and a funnel-shaped second cavity that are interconnected to form a gradually changing shielding channel. When it is interfered with, it can guide the external electromagnetic interference wave to be reflected and attenuated in the cavity, so that the interference signal is weakened after multiple reflections in the cavity, thereby improving its anti-interference ability.

[0021] 2. This dual-magnetic-ring strong anti-interference wire harness, with its sleeve made of thermoplastic elastomer material, possesses high flexibility and wear resistance. Furthermore, the high magnetic permeability of the magnetic ring assembly suppresses electromagnetic interference, further enhancing its anti-interference capability. Through the cooperation of the first, second, and third through slots, the connecting wire harness passes through them, forming a two-layer winding with the magnetic ring assembly, thus improving its anti-interference ability and creating a dual-magnetic-ring filter structure that can suppress interference sources in different frequency bands.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: As Figure 1-8 As shown, the present invention provides a double magnetic ring strong anti-interference wire harness including a first connector 1, a connecting wire harness 2 and a second connector 6. A sleeve assembly 3 is provided at the outer edge of the other end of the connecting wire harness 2 away from the first connector 1, and a magnetic ring assembly 5 is provided at the outer edge of the other end of the connecting wire harness 2 away from the sleeve assembly 3.

[0033] The sleeve assembly 3 includes a sleeve body 301 and a connecting sleeve 305. A first cavity 302 is provided at the inner edge of the sleeve body 301. A buckle 303 is provided at the inner edge of the first cavity 302. A rubber ring 304 is fixedly installed at the inner edge of the sleeve body 301. A second cavity 306 is provided at the inner edge of the connecting sleeve 305.

[0034] Specifically, the first cavity 302 and the second cavity 306 are interconnected. The cross-section of the second cavity 306 is funnel-shaped. The advantage is that the first cavity 302 and the funnel-shaped second cavity 306 are interconnected, forming a gradually changing shielding channel. When interfered with, the external electromagnetic interference wave can be guided to reflect and attenuate in the cavity, so that the energy of the interference signal is weakened after multiple reflections in the cavity, thereby improving its anti-interference ability.

[0035] Specifically, the sleeve body 301 is a thermoplastic elastomer, and the buckle 303 is located on the inner wall of the first cavity 302 and at the end away from the connecting sleeve 305. The advantage is that the sleeve body 301, made of thermoplastic elastomer, has high flexibility and wear resistance. When the wire harness is bent, it is not easy to be damaged, which can easily adapt to complex wiring scenarios. In addition, with the design of the buckle 303, since it is located on the inner wall of the first cavity 302, when the connecting wire harness 2 passes through, it can tighten and compress the outer layer of the wire harness.

[0036] Specifically, the connecting wire harness 2 passes through the magnetic ring assembly 5 and extends to its other end. A ferrite ring 7 is provided at the outer edge of the magnetic ring assembly 5. The advantage is that when the connecting wire harness 2 passes through the magnetic ring assembly 5, electromagnetic interference is suppressed by the high permeability of the magnetic ring assembly 5. When the interfering magnetic field passes through the magnetic ring assembly 5, the magnetic domain movement generates hysteresis loss, which converts electromagnetic energy into heat energy, thus playing a role in interference suppression and further improving its anti-interference ability.

[0037] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, the magnetic ring assembly 5 includes a first magnetic ring sleeve 501 and a second magnetic ring sleeve 507. The inner edges of the first magnetic ring sleeve 501 and the second magnetic ring sleeve 507 are provided with a first through groove 502, a second through groove 503 and a third through groove 504. The connecting wire harness 2 passes through the first through groove 502, the second through groove 503 and the third through groove 504 and extends to its outer edge. The advantage is that, through the cooperation of the first through groove 502, the second through groove 503 and the third through groove 504, the connecting wire harness 2 can pass through the first through groove 502, the second through groove 503 and the third through groove 504, and then the connecting wire harness 2 and the magnetic ring assembly 5 can form two layers of winding, which can improve its anti-interference ability.

[0039] Specifically, a slot 505 is provided on the outer edge of the first magnetic ring sleeve 501. A rotating rod 506 is fixedly installed at the other end of the first magnetic ring sleeve 501 away from the slot 505. A second magnetic ring sleeve 507 is rotatably installed on the first magnetic ring sleeve 501 via the rotating rod 506. An extension plate 508 and a locking piece 509 are fixedly installed at the end of the second magnetic ring sleeve 507 near the slot 505. The locking piece 509 is snapped into the slot 505. The cross-section of the end of the locking piece 509 near the slot 505 is at an angle. The structure is shaped like a " ". The locking element 509 is a plastic elastic locking element. Its advantage is that, through the cooperation of the rotating rod 506 and the locking element 509, when connecting, the locking element 509 can be inserted into the slot 505, which can realize the connection of the first magnetic ring sleeve 501 and the second magnetic ring sleeve 507. Furthermore, the angled locking element 509 can be easily inserted into the slot 505 to lock the two together. The rotating rod 506 can facilitate the opening and closing of the first magnetic ring sleeve 501 and the second magnetic ring sleeve 507.

[0040] Specifically, a label 4 is provided on the outer edge of the connecting harness 2. At least two identical labels 4 are provided. The advantage is that the label 4 on the outer edge of the harness is used to identify the function, specifications or route of the harness, which facilitates the differentiation of the wiring during installation and the subsequent maintenance and management. It also makes it easier for staff to quickly connect the function of the harness body 2 and other data.

[0041] Working principle: During use, the first cavity 302 and the funnel-shaped second cavity 306 are interconnected, forming a gradually changing shielding channel. When interference occurs, it can guide the external electromagnetic interference wave to reflect and attenuate within the cavity, reducing the energy of the interference signal after multiple reflections within the cavity, thus improving its anti-interference capability. The sleeve body 301, made of thermoplastic elastomer material, has high flexibility and wear resistance, making it less prone to damage when the wire harness is bent, and easily adaptable to complex wiring scenarios. In addition, the design of the buckle 303, located on the inner wall of the first cavity 302, can tighten and compress the outer layer of the wire harness 2 when it passes through. When the wire harness 2 passes through the magnetic ring assembly 5, the high magnetic permeability of the magnetic ring assembly 5 suppresses electromagnetic interference. When the interfering magnetic field passes through the magnetic ring assembly 5, the magnetic domain movement generates hysteresis. The loss converts electromagnetic energy into heat energy, which can play a role in suppressing interference and further improve its anti-interference ability. Through the cooperation of the first through slot 502, the second through slot 503 and the third through slot 504, the connecting wire harness 2 can pass through the first through slot 502, the second through slot 503 and the third through slot 504. Then, the connecting wire harness 2 and the magnetic ring assembly 5 can form two layers of winding, which can improve its anti-interference ability. Through the cooperation of the rotating rod 506 and the locking piece 509, when connecting, the locking piece 509 can be inserted into the locking slot 505, which can realize the connection of the first magnetic ring sleeve 501 and the second magnetic ring sleeve 507. The angled locking piece 509 can be easily inserted into the locking slot 505 to realize the locking of the two. The rotating rod 506 can facilitate the opening and closing of the first magnetic ring sleeve 501 and the second magnetic ring sleeve 507.
