Circuit structure of plastic-housing-based internet access connector with high electromagnetic compatibility

Disclosed in the utility model is a circuit structure of a plastic-housing-based internet port connector with high electromagnetic compatibility. The circuit structure is formed by an internet port, a transformer, a smith circuit, a medium access control layer, and a physical layer. A first pin, a second pin, a third pin, a fourth pin, a fifth pin, a sixth pin, a seventh pin, and an eighth pin are successively distributed in the internet port; and the first pin, the second pin, the third pin, and the sixth pin are connected with other network devices by cables. The structure is characterized in that the fourth pin, the fifth pin, the seventh pin, and the eighth pin are arranged in a suspended mode. According to the technical scheme, all interfering energy can be transmitted to the transformer; and when passing through the transformer, the energy is affected by the inhibiting effect of the common mode inductor, so that the interfering energy can not enter the working circuit and thus the normal working of the working circuit can be protected from the interference. Therefore, the circuit is protected and the product performance is improved.
