A multi-core tensile network cable

Abstract

The invention discloses a multi-core tensile network cable, include a protective coat, a reinforcing layer, a support layer and a core layer, the inner side of the protective outer layer is provided with a reinforcing layer, A plurality of first reinforcing ribs are arranged in the reinforcing layer, the axial direction of the reinforcing rib is arranged parallel to the axial direction of the network line, the inner side of the reinforcing layer is provided with a support layer, The inner side of the support layer is provided with a core wire layer, and the core wire layer sequentially comprises an insulating outer film, a filler, an insulating inner film and a plurality of core wires from the outside to the inside. The core wire is formed by screwing a plurality of wires, and the insulating inner film is wrapped on the outer side of the core wire. A filler is arranged between the insulating outer film and the insulating inner film. The invention discloses a multi-core tensile networkwire, which is simple in structure, comprises a plurality of first reinforcing ribs in a reinforcing layer and a plurality of second reinforcing ribs in a supporting layer, wherein the reinforcing ribs can improve the ductility and tensile performance of the network wire, so that the network wire is not easy to be damaged or broken when subjected to axial tensile force.

Description

【Technical field】 [0001] The invention relates to the technical field of network cables, in particular to the technical field of multi-core tensile network cables. 【Background technique】 [0002] A network cable is essential for connecting to a LAN. The common network cables in the local area network mainly include twisted pair, coaxial cable and optical cable. A twisted pair is a data transmission line composed of many pairs of wires. It is characterized by low price, so it is widely used, such as our common telephone lines. It is used to connect with the RJ45 crystal head. [0003] The network cable in the traditional technology has poor tensile strength. Users often pull the network cable when using and installing the network cable. If the tensile performance is insufficient, it is easy to cause the inner core wire or jacket of the network cable to break, which not only affects normal use, The connection is prone to problems and may cause dangerous accidents, so it is...

Problems solved by technology

[0003] The network cable in the traditional technology has poor tensile strength. Users often pull the network cable when using and installing the network cable. If the tensile performance is insufficient, it is easy to cause the inner core wire or jacket of the network cable to break, which not only affects normal use, The connection is prone to problems and may cause dangerous accidents, so it is necessary to propose a network cable with better tensile properties
