[0002] Coaxial cable is a type of electrical wire and signal transmission line, generally made of four layers: the innermost layer is a conductive copper wire, surrounded by a layer of plastic as insulation and dielectric, then a thin mesh of conductive material, usually copper or an alloy, and finally the outermost insulating material as a sheath. Coaxial cable can be used to transmit analog and digital signals and is suitable for a wide variety of applications, most notably cable television transmission, long-distance telephone transmission, short-distance connections between computer systems, and local area networks. Coaxial cable has developed rapidly as a means of transmitting television signals to households, which is the origin of cable television.

For a long time, coaxial cable has been an important component of long-distance telephone networks.

[0003] Currently, conventional coaxial cables have the following problems in use: first, they lack quick-connect structures, making connection cumbersome; second, they are susceptible to electromagnetic interference, affecting their transmission performance. Therefore, those skilled in the art have provided highly shielded, quick-connect coaxial cables to solve the problems mentioned in the background. Utility Model Content

[0022] Please see Figures 1-4 In this embodiment of the invention, the high-shield, fast-connect coaxial cable includes a sheath 1. The sheath 1 includes an anti-corrosion layer 101, an outer shielding layer 102, a sound-absorbing layer 103, a flame-retardant layer 104, an inner shielding layer 105, and an insulation layer 106. A baffle 2 is fixedly connected to the outer surface of the sheath 1. A connecting cover 4 is fitted over the outer surface of the sheath 1. A fixing block 5 is fixedly connected to the outer surface of the sheath 1. A conductor 10 is fixedly connected to the inner wall of the sheath 1. An insertion hole 6 is provided at the rear end of the fixing block 5. The outer surface of the insulation layer 106 is fixedly connected to the inner shielding layer 105, and the outer surface of the inner shielding layer 105 is fixedly connected to the inner shielding layer 105. The flame-retardant layer 104 is fixedly connected, the outer surface of the flame-retardant layer 104 is fixedly connected to the sound-absorbing layer 103, the outer surface of the sound-absorbing layer 103 is fixedly connected to the outer shielding layer 102, and the outer surface of the outer shielding layer 102 is fixedly connected to the anti-corrosion layer 101. This not only facilitates the connection of cables but also improves the shielding effect of cables, thereby solving the following problems that exist in the use of general coaxial cables: first, the lack of a quick connection structure makes connection cumbersome; second, the cable is affected by electromagnetic fields during use, resulting in interference and affecting its transmission performance.

[0023] The diameter of the socket 6 is compatible with that of the conductor 10. The anti-corrosion layer 101 is made of perfluoroalkoxy resin material, the outer shielding layer 102 is made of copper wire and copper strip composite metal, the sound-absorbing layer 103 is made of porous glass wool, the flame-retardant layer 104 is made of fireproof polyester fiber cotton, and the inner shielding layer 105 is an ultra-thin conductive PVC shielding mesh. This allows the cable to have the characteristics of corrosion resistance, high shielding and fire resistance at the same time, thereby greatly increasing the service life of the cable.

[0024] The inner wall of the connecting cover 4 has an internal thread 8, the outer surface of the fixing block 5 has an external thread 9, the outer surface of the conductor 10 is fixedly connected to the insulation layer 106, the front of the baffle 2 is fixedly connected to a rubber pad 3, the outer surface of the connecting cover 4 has anti-slip texture 7, and the insulation layer 106 is made of polyolefin material, which can facilitate people to quickly connect cables.

[0025] The working principle of this utility model is as follows: First, the conductor 10 can be inserted into the socket 6, and then the connecting cover 4 can be rotated using the internal thread 8 and the external thread 9. The connecting cover 4 can prevent the cable from falling off or shaking at the connection point, thereby affecting the transmission performance of the cable. During the operation of the cable, the sound-absorbing layer 103 can absorb the noise generated by the cable during operation, the outer shielding layer 102 and the inner shielding layer 105 can block external magnetic fields and signals, the flame-retardant layer 104 can prevent external high temperature from damaging the cable, and the anti-corrosion layer 101 can prevent corrosion on the surface of the cable after long-term use, thereby reducing the service life of the cable.
