Abstract
Description
Technical Field
[0001] This utility model relates to the field of wires and cables, specifically to an anti-electromagnetic interference composite shielded wire and cable. Background Technology
[0002] Wires and cables are wire products used to transmit electrical energy, electrical signals, or realize electromagnetic energy conversion. In a broad sense, they include all conductor products; in a narrow sense, they specifically refer to multi-core cables with an insulation layer. Anti-electromagnetic interference composite shielded wires and cables are special cables that have an added shielding layer on the basis of ordinary wires and cables. Their main purpose is to reduce the impact of external electromagnetic interference on signal transmission. Through its special structure and material design, this type of cable provides a highly efficient electromagnetic shielding effect, ensuring the purity and stability of the signal. Existing composite wires and cables have weak anti-shielding and anti-electromagnetic interference performance, which cannot meet people's needs. At the same time, the outer sheath of wires and cables is often pulled, which can easily cause breakage.
[0003] To address the aforementioned issues, the electromagnetic interference-resistant composite shielded wire and cable with Chinese patent publication number CN213400649U allows users to add a strong fiber braided layer to the outside of the cable's outer sheath during operation. This enhances the protective performance of the outer sheath. The spirally arranged strong fiber braided layer evenly wraps around the outside of the outer sheath, increasing its tightness and reducing the likelihood of breakage. By sequentially wrapping the shielding layer and the electromagnetic interference-resistant layer around the outside of the wire core, the cable achieves high-strength shielding performance, meeting user needs and facilitating future promotion.
[0004] While the comparative patent addresses the weak shielding and electromagnetic interference resistance of composite wires and cables, failing to meet people's needs, and the fact that the outer sheath of the wires and cables is easily broken due to frequent pulling, the device's protective effectiveness is reduced when used underground. This is because underground creatures such as rats may bite the cables, leading to cable damage.
[0005] Regarding the aforementioned technologies, when this device is used underground, it is prone to damage to the cable due to creatures such as rats gnawing at it, thus reducing the protective effect of the device. Utility Model Content
[0006] (a) Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this utility model provides an anti-electromagnetic interference composite shielded wire and cable. When the anti-bite layer is torn or damaged, the chemical powder will be released. The powder has a highly irritating odor, which can repel the biting organisms and improve the protection of the device. This solves the problem that when used underground, rodents and other organisms may bite the cable, easily causing damage and reducing the protection of the device.
[0008] (II) Technical Solution
[0009] To achieve the goal of repelling biting organisms and improving the protection of the device by releasing chemical powder when the anti-biting layer is torn, the present invention provides the following technical solution: an anti-electromagnetic interference composite shielded wire and cable, comprising a binding sleeve, an internal wire assembly, an anti-electromagnetic interference layer fixedly sleeved on the outer wall of the binding sleeve, a shielding layer fixedly sleeved on the outer wall of the anti-electromagnetic interference layer, a waterproof layer fixedly sleeved on the outer wall of the shielding layer, a protective sleeve fixedly sleeved on the outer wall of the waterproof layer, and a protective component inside the protective sleeve.
[0010] As a preferred embodiment of the present invention, the wire assembly includes a filler layer and a wire core, wherein the wire core is located inside the binding sleeve, and the filler layer fills the space between the wire core and the binding sleeve.
[0011] As a preferred technical solution of this utility model, the protective component includes a receiving cavity formed in the inner wall of the protective sleeve, the inner wall of the receiving cavity is fixedly sleeved with a metal covering layer, and the inner wall of the receiving cavity is fixedly connected with a wear-resistant component.
[0012] As a preferred technical solution of this utility model, the wear-resistant component includes a wear-resistant layer fixedly connected to the inner wall of the receiving cavity, and the inner wall of the wear-resistant layer is provided with a receiving groove, and the receiving groove is provided with medicine powder.
[0013] As a preferred embodiment of this utility model, the outer wall of the protective sleeve is fixedly fitted with an anti-corrosion layer.
[0014] As a preferred embodiment of this invention, a wear-resistant layer is fixedly sleeved on the outer wall of the anti-corrosion layer.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides an anti-electromagnetic interference composite shielded wire and cable, which has the following beneficial effects:
[0017] 1. A metal sheath is wrapped around the inner wall of the containment cavity. When the protective sleeve is torn or damaged, the metal sheath will bite before contacting the wire core. The metal sheath is made of a relatively hard metal material, which can prevent biting. The bite-resistant layer is made of a highly elastic material, which will reflect the force back to the biting creature when it is bitten, thus providing a protective function. When the bite-resistant layer is torn, the chemical powder will be spilled out. The chemical powder has a very irritating odor, which can repel the biting creature, thus improving the protection of the device.
[0018] 2. An anti-corrosion layer is fixedly fitted onto the outer wall of the protective sleeve. The anti-corrosion layer is a protective material located on the outermost layer of the device, thus playing a role in corrosion prevention. A wear-resistant layer is fixedly fitted onto the outer wall of the anti-corrosion layer. The wear-resistant layer is in direct contact with the external soil or ground, which will cause friction. The wear-resistant layer is a wear-resistant material, thus playing a role in wear resistance. Attached Figure Description

A metal sheath 10 is fixedly sleeved on the inner wall of the receiving cavity 9. A bite-resistant component is fixedly connected to the inner wall of the receiving cavity 9. The metal sheath 10 is wrapped around the inner wall of the receiving cavity 9. Therefore, when the protective sleeve 7 is torn and damaged, it will bite the metal sheath 10 before contacting the wire core 3. The metal sheath 10 is made of a relatively hard metal material, which can play a role in preventing biting.
[0029] Reference Figure 1-4 The chew-resistant component includes a chew-resistant layer 11 fixedly connected to the inner wall of the receiving cavity 9. The inner wall of the chew-resistant layer 11 has a receiving groove 13, and the receiving groove 13 contains a medicine powder 12. The chew-resistant layer 11 is made of a highly elastic material, so when it is bitten, it will reflect the force back to the biting creature, thus playing a protective role. When the chew-resistant layer 11 is bitten and damaged, the medicine powder 12 will be spilled out. The medicine powder 12 has a very pungent odor, which can drive away the biting creature.
[0030] Specifically, the outer wall of the protective sleeve 7 is fixedly fitted with an anti-corrosion layer 8, which is a protective material located on the outermost layer of the device, thus playing a role in corrosion prevention.
[0031] Furthermore, a wear-resistant layer is fixedly sleeved on the outer wall of the anti-corrosion layer 8. The wear-resistant layer is in direct contact with the external soil or ground, which will cause friction. The wear-resistant layer is made of wear-resistant material, which can achieve the effect of wear resistance.
[0032] During use, the metal sheath 10 is wrapped around the inner wall of the receiving cavity 9. When the protective sleeve 7 is torn and damaged, it will bite the metal sheath 10 before contacting the wire core 3. The metal sheath 10 is made of a relatively hard metal material, which can prevent biting. The bite-resistant layer 11 is made of a highly elastic material, which will reflect the force back to the biting creature when it is bitten, thus playing a protective role. When the bite-resistant layer 11 is torn and damaged, the chemical powder 12 will be spilled out. The chemical powder 12 has a very irritating odor, which can drive away the biting creature.
[0033] The outer wall of the protective sleeve 7 is fixedly fitted with an anti-corrosion layer 8.
