Grounding structure of the inner shield of the cable of the connector

The present invention relates to a grounding structure of a cable inner shield of a connector. In particular, it refers to a grounding structure of an inner cable shield of a connector that can be automatically produced therefrom.

The circuit is inevitably affected by various internal factors or external factors, which affects the correctness of its operation. For example, the interference voltage acting between the two poles of the signal is mainly caused by the coupling of the electromagnetic electromagnetic field between the signals and the voltage formed by the unbalanced circuit to convert the common mode interference, which is directly superimposed on the signal, directly affecting the measurement and control precision. Most of the circuit layouts of the conventional electronic devices are exposed on the surface of the printed circuit board, which is inevitably affected by the electromagnetic induction of the electromagnetic field (Electromagnetic Interference (EMI) or Radio Frequency Interference (Radio Frequency Interference). The trouble of RFI for short.

In order to prevent the interference of the external incoming magnetic field, the cable for transmitting signals will be covered with an inner layer of a metal mesh on the outer layer of the inner layer after the insulating layer is first added to the outer layer of the inner layer. It has two main functions. One is to shield the electromagnetic field generated when the cable is energized in the insulated core to reduce electromagnetic interference to the outside world; the other is to safely introduce the fault current in the design range generated by the system into the grounding system. The protection system operates safely. The inner shield made of this metal mesh acts as a short-circuit current channel when the system is short-circuited, and also plays a role of shielding the electric field.

However, when connecting multiple cables to the connector, the inner shield of each cable must be twisted before being connected to the ground source of the connector. This manufacturing method has the following disadvantages:

1. In the manufacturing process, the action of the inner shield layer to be twisted first must be done manually, and cannot be automatically produced, which has long been a problem for the process.

2. After the twisting, the inner shield layer has a large cross section, which inevitably takes up a large space, which is not conducive to miniaturization of the connector.
