Description

Technical Field

[0001] The utility model relates to a network cable, in particular to an anti-interference network cable. Background Art

[0002] Since the network cable involves the transmission of a large amount of data and high-frequency signal interaction, the electromagnetic waves in the environment may interfere with it. In the prior art, one or more metal layers are generally provided in the PVC protective sheath of the network cable to shield the interference signal. For example, a Chinese patent discloses an anti-interference network cable, patent number 202120844244.3, which states: including a wire body, a buffer cavity is provided inside the wire body, and several groups of twisted pair wires and several ground wires are embedded inside the wire body, and the ground wires are abutted against the twisted pair wires. Several groups of twisted pair wires include an anti-electromagnetic layer and several signal wires. The outer surface of the wire body is provided with a metal film wrapped in a surrounding manner, and the outside of the metal film is provided with an insulating layer that fully covers the wire. The wire body, the metal film and the insulating layer are tightly fitted and fixed in sequence. The material of the anti-electromagnetic layer is aluminum. The material of the metal film is copper. The anti-electromagnetic layer abuts against the ground wire, and the anti-electromagnetic layer fully covers and wraps the signal wire.

[0003] The shortcomings of the existing technology are that the existing network cables are all covered with insulating PVC protective covers, and static electricity is easily generated and accumulated on the surface of the network cables during the winding, unwinding and installation processes of the network cables. The grounding components inside the network cables (such as aluminum foil and copper foil) require special connectors and are connected to the ground wire to eliminate static electricity. At present, the national standards of my country's network cable sockets, routers and other equipment do not require the installation of ground wires. In other words, the grounding components inside the network cables cannot eliminate static electricity at all. Summary of the invention

[0004] In view of the shortcomings of the prior art, the utility model provides an anti-interference network cable, which has an anti-interference effect and an effect that static electricity is not easily accumulated on the surface.

[0005] The technical solution of the utility model is:

[0006] An anti-interference network cable includes a wire body, the wire body includes a PVC protective sleeve and 4 groups of wire cores, the outer periphery of the PVC protective sleeve is provided with an antistatic finishing agent layer, each group of wire cores is coated with a layer of rib fabric, the rib fabric is woven with double-twisted yarn, and the double-twisted yarn is obtained by twisting hollow filaments and conductive wires. The hollow filaments play a role in enhancing the mechanical strength of the yarn and playing a buffering role, and the conductive wire plays a role in shielding interference signals. The antistatic finishing agent layer is conducive to the conduction and dissipation of static electricity.

[0007] In a preferred embodiment of the present disclosure, a conductive sleeve is provided outside the cable body, and the conductive sleeve is a circular conductive plastic sleeve that matches the shape of the cable body, so that the user can move the conductive sleeve to a position that is convenient for connecting the ground wire or grounding, thereby eliminating static electricity for the network cable.

[0008] In a preferred embodiment of the present disclosure, at least one conductive plastic strip is connected to the outer periphery of the conductive sleeve, and the conductive plastic strip naturally hangs down and contacts the ground, thereby achieving grounding and eliminating static electricity without the need for external equipment.

[0009] In a preferred embodiment of the present disclosure, the conductive sleeve is provided with a tension adjustment mechanism for locking.

[0010] In a preferred embodiment of the present disclosure, a counterweight block is provided at the end of the conductive plastic strip to facilitate the conductive plastic strip to naturally droop and ground.

[0011] Beneficial effects of the utility model

[0012] According to the present disclosure, yarn is obtained by twisting hollow filaments and conductive wires, and the yarn is woven into a fabric to wrap each group of wire cores, which plays a role in shielding interference signals, and the hollow filaments have the function of enhancing the mechanical strength of the fabric; the PVC protective cover is treated with an antistatic finishing agent to prevent static electricity from accumulating on its surface and facilitate charge diffusion.
