What is the connection method of the CCTV socket 

First, strip the outer sheath of the cable. When doing this step, everyone must be careful not to damage the shielding network, because the quality of the ratings depends entirely on the shielding network. If the tin-plated shielding layer is too damaged, it will directly affect the final ratings. Then remove the shielding layer and fold it outward. Since the inner layer of the aluminum composite film is an insulating layer, once it is folded over, it will affect the normal conduction, so this section of the aluminum composite film needs to be cut off. Then strip the insulation layer of the core wire,

When stripping, pay attention to that the length of the core wire should be the same as that of the plug. Connect the plug, tighten the copper core with the fixing screws, and check whether the shielding layer holder is well connected with the metal shielding wire. The role of the shielding layer holder here can be said to be very important. In addition to the role of fixing the metal shielding wire, it also serves as a bridge between the shielding layer and the metal shell of the plug. The metal shell of the plug is connected with the metal shell of the antenna interface of the TV card and connected to the ground of the TV card. At this point, a complete shielding channel is completed, and the external conductive effect of the tinned shielding net can be truly brought into play. The final job is to tighten the plug. There is one more thing that needs to be reminded-the firmness of the plug. Once encountered such a situation, a friend did all the previous steps very well: the insulation layer was stripped very horizontally and the metal shielding net was basically not damaged, but the effect was not ideal. Often the wiring screen will suddenly become very clear when you move it, but it won't work when you loose your hand. It was discovered after inspection that the problem was that the plug was not tightened.
