Description

[0002] Smart home appliances are home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. The network is the basis for the operation of smart home appliances. Most of them use Netcom's RF coaxial line to connect to complete the networking. The RF coaxial line consists of four parts: inner conductor, insulator, outer conductor and sheath. The dielectric determines the transmission speed and loss characteristics of the coaxial line to a large extent. The coaxial line is an indispensable signal transmission device for connecting routers and smart home appliances in modern life. By installing and connecting the coaxial line, the smart home appliances in the home can be directly controlled by the router. The coaxial line is a shielded and non-dispersive structure, and the main mode of the waveguide in the coaxial line is TEM wave, but it can also transmit TE mode and TM mode. Its cut-off frequency is zero, and the corresponding cut-off wavelength tends to infinity. It is a double-conductor transmission line composed of two inner and outer conductors of the coaxial line and the dielectric in the middle. Generally, the outer conductor of the coaxial line is grounded, and the electromagnetic field is limited between the inner and outer conductors. Therefore, the coaxial line has basically no radiation loss and is almost not interfered by external signals. Its working frequency band is wider than that of the double-wire transmission line and can be used for bands greater than centimeter waves.

[0003] In the prior art, the interior of the coaxial cable is mostly installed with a braided layer made of metal wire, which can effectively improve the tensile strength of the coaxial cable, making the coaxial cable less prone to damage and greatly increasing its service life.
