Abstract

The present application discloses a communication control device, which includes a first circuit board electrically connected to a second circuit board, the second circuit board electrically connected to an interface board, the second circuit board includes at least one lightning protection module, and the lightning protection module has a The first-level lightning protection circuit and the second-level lightning protection circuit. When the external interface of the interface board receives a transient overvoltage / overcurrent, there will still be a high residual voltage after passing through the first-level lightning protection circuit, and the second-level lightning protection circuit will The residual voltage is further reduced to a lower voltage, and the voltage is clamped at a permissible value. This permissible voltage value can be tolerated by the first circuit board protected in the subsequent stage, thereby preventing the internal components of the first circuit board from being subjected to transient overvoltage / Damaged by the impact of overcurrent. The first circuit board and the second circuit board are electrically connected through the plug-in of metal components and are supported and fixed to each other. The integrated design can not only effectively reduce the size of the circuit design, reduce the complexity of manufacturing, but also reduce the residual voltage of the circuit and the subsequent Sensitive circuit problems.

Description

technical field [0001] The present application relates to the technical field of independent design and signal integration design of a lightning protection circuit and a communication control circuit, and particularly relates to a communication control device. Background technique [0002] Communication places have certain requirements for lightning protection and surge protection. It is very important to use overvoltage protection and overcurrent protection components in communication devices. Lightning surge protection is the key to protecting the safety of communication devices and normal communication. [0003] As for the protection of communication devices, the lightning protection circuit and the main circuit are designed on the same main circuit board. This design will cause the main circuit board to be too large. Since the main circuit is a low-voltage circuit, the lightning protection circuit is a high-voltage circuit. , If the low-voltage circuit and the high-volta...
