Abstract

The application discloses a communication control device. A first circuit board is electrically connected with a second circuit board. The second circuit board is electrically connected with an interface board. The second circuit board contains at least one lightning protection module. The lightning protection module has a first-stage lightning protection circuit and a second-stage lightning protection circuit. When the external interface of the interface board receives a transient overvoltage / over-current, there will still be a high residual voltage after the current flows through the first-stage lightning protection circuit, and the second-stage lightning protection circuit will further reduce the residual voltage to a lower voltage and clamp the voltage at an allowable value. The allowable value is tolerable for the protected first circuit board in the later stage, so that the internal components of the first circuit board will not be damaged by the impact of the transient overvoltage / over-current. The first circuit board and the second circuit board are electrically connected through insertion of a metal component and are supported and fixed by each other. The integrated designcan not only reduce the volume of the circuit and the complexity of manufacture, but also reduce the residual voltage of the circuit and 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...
