Kinghelm R&D, production and sales of electronics - line radio frequency line coaxial cable

The electronic line RF line coaxial cable of Jinhangbiao Electronics (www.bds666.com) builds a bridge between electronic signals and radio frequency signals between two or more isolated and unconnected electronic circuits, thereby enabling current and radio frequency signals to flow and realizing various functions of various components. It is an indispensable component in various electrical and electronic equipment. To identify the quality of electronic line, radio frequency line, coaxial cable connection terminal, detection requires special equipment and instruments. In actual engineering, preliminary identification can be carried out according to the following methods:

1. Check the core diameter of the silicone electronic wire: SYV cable has a diameter of 0.78 to 0.8mm, and SYWV cable has a diameter of 1.0mm. Recently, a SYV75-5 cable with a core diameter of 1.0mm has appeared. The characteristic impedance of this cable must not reach 75Ω and should not be used in 75Ω transmission systems.
​​ 2. Check the braiding of the shielding layer metal wires: whether the number of braids is enough, check the weldability of the copper braiding, and scrape the tinned copper wire to see if there is copper wire inside. The hardness of the aluminum-magnesium alloy wire is obviously greater than that of the copper wire; the braiding is sparse and unevenly distributed, and the insulation layer is not tightly wrapped, etc. It is a poor cable.
3. Check the adhesion between the metal wire core and the insulating layer: cut the insulating layer diagonally and pull the core wire in the peeling direction to see if the core wire and the insulating layer are bonded with process materials. Good cables have greater adhesion, while poor cables have no adhesion. Longitudinal tensile test: Take the morning cable about one meter in length, peel off the core wires, insulation layer, shielding layer and outer sheath in layers, leaving 250px long each. The method is: hold the two adjacent layers of the cable with both hands and pull in opposite directions; good cables generally cannot be pulled out with force, but poor cables can be easily pulled out without much effort.
4. Observe the PVC sheath with the naked eye: Regular "irregularities" in the compressed mesh inside can be seen on the surface, indicating that the processing technology is good and there will be no relative sliding. It is a good cable; the appearance is smooth, and the "unevenness" of the compressed mesh and the texture of the wire cannot be seen. If the sheath feels loose when pinched by hand, it is a poor cable RF line coaxial cable.

Kinghelm (www.bds666.com) company launched the HDMI interface connector based on the previous development and production of Beidou antenna and GPS antenna cable. The HDMI interface is a dedicated digital interface suitable for image transmission. It can be used for cable TV set-top boxes, DVD players, personal computers, video game consoles, integrated amplifiers, digital audio and televisions. It can also transmit audio and video signals at the same time. HDMI can not only meet the resolution of 1080P, but also support digital audio formats such as DVD Audio. It supports eight-channel 96kHz or stereo 192kHz digital audio transmission, and can transmit uncompressed audio signals and video signals with high quality. A variety of kinghelm brand HDMI interfaces and HDMI connectors developed and produced by Jinhangbiao Company have received very good response after being put into the market! The application benefit of Jinhangbiao HDMI interface is that only one HDMI cable is needed to transmit audio and video signals at the same time. At the same time, due to wireless digital/analog or analog/digital conversion, higher audio and video transmission quality can be achieved, which is widely loved by consumers.
