Network cable with high safety

Abstract

The utility model discloses a network cable with high safety, which comprises a plastic protective layer, eight thin wires are arranged in the plastic protective layer, a mica tape is wound outside each thin wire, every two thin wires wound with the mica tapes are wound together to form a twisted pair, a shielding layer is wrapped outside each twisted pair, and the shielding layer is wrapped outside the plastic protective layer. The outer side of the shielding layer of the four twisted pairs is a braid layer, and the outer side of the braid layer is a plastic protection layer. According to the utility model, the mica tape is wound on each thin wire of the twisted pair, so that when the wires are overheated to burn off an external insulating layer, the wires are blocked by the mica tape on the outer side and cannot be contacted together immediately, thereby causing short circuit.

Description

Technical Field

[0001] The utility model relates to the field of cable manufacturing and processing, in particular to a network cable with high safety. Background Art

[0002] A network cable is a cable used to connect various network devices, such as computers, routers, switches, etc., to transmit data, sound, and video signals.

[0003] The primary function of a network cable is to transmit data from one network device to another. There are many different types of network cables, categorized by various criteria, such as transmission rate, transmission medium, application, structure, and interface. Common types of network cables include twisted pair (for low-speed transmission), fiber optic (for high-speed transmission), and shielded twisted pair (to reduce electromagnetic interference).

[0004] When the equipment circuit is overloaded or used for too long, the temperature of the twisted pair in the cable increases. When the temperature is too high, the insulation layer on the outside will burn off, causing the two wires to touch each other, resulting in a short circuit. If it is not discovered in time, it will burn the equipment, causing property loss and safety accidents. Utility Model Content

[0005] The utility model aims to provide a network cable with high safety, which has the advantage of prolonging the time before a short circuit occurs.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A highly secure network cable comprises a plastic protective layer with eight thin conductors within the plastic protective layer. The outside of each thin conductor is wrapped with mica tape, and two of the thin conductors wrapped with mica tape are twisted together to form a twisted pair. The outside of each twisted pair is coated with a shielding layer. The outside of the shielding layer of the four twisted pairs is a braided layer, and the outside of the braided layer is a plastic protective layer.

[0008] With the above technical solution, when the temperature of the thin wire is too high and burns off its outer insulation layer, the two wires are blocked by the mica tape wrapped around the outside of the insulation layer and will not touch each other immediately, providing more time for discovering and solving the problem, and reducing the possibility of burning the equipment.

[0009] Preferably, the shielding layer is aluminum foil.

[0010] The above technical solution is used to isolate the interference of electromagnetic signals from the outside world and between twisted pairs, while increasing the fire prevention effect.

[0011] Preferably, the braided layer is woven from copper wires or tinned wires.

[0012] The above technical solution is adopted to further improve the shielding effect against external electromagnetic signals.

[0013] Preferably, glass wool is filled between the twisted pair and the braided layer.

[0014] The above technical solution is adopted to increase the insulation performance and tensile strength of the cable.

[0015] In summary, the network cable has high safety and good durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions based on the principles of the present invention should be included in the scope of protection of the present invention. It should also be noted that improvements and modifications that do not depart from the principles of the present invention by ordinary skill in the art should also be considered within the scope of protection of the present invention.

[0019] See Figure 1 A highly secure network cable comprises a plastic protective layer 1, wherein the plastic protective layer 1 contains four twisted pairs of wires, wherein the two thin conductors 2 of each twisted pair of wires are each wrapped with a mica tape 3, and the outer side of the mica tape 3 of each twisted pair of wires is covered with an aluminum foil shielding layer 4, which is used to isolate the interference of electromagnetic signals from the outside world and between the twisted pairs, while increasing the fire prevention effect. The outer side of the shielding layer 4 of the four twisted pairs of wires is a braided layer 5, which is woven from copper wire or tinned wire to further improve the shielding effect against external electromagnetic signals. Glass wool is filled between the twisted pairs and the braided layer 5 to increase the insulation performance and tensile strength of the cable, and the outer side of the braided layer 5 is a plastic protective layer 1.

[0020] Working principle: When the temperature of the thin wire 2 is too high and its outer insulation layer is burned off, the mica tape 3 is wrapped around the outside of the insulation layer. The two wires are blocked by the mica tape 3 and will not touch each other immediately, providing more time for discovering and solving problems, and reducing the possibility of burning equipment.
