Data transmission module with protection function

Abstract

The invention discloses a data transmission module with a protection function, and belongs to the technical field of data transmission devices in mobile communication equipment. The module comprises an isolation transformer, a semiconductor device, a PCB for fixing the semiconductor device and a shell, the isolation transformer is mounted at a wiring end of the shell, a plated-through hole is reserved in the PCB, and the wiring end is welded and fixed with the plated-through hole. The data transmission module provided by the invention has relatively high security, can cope with surge, overvoltage, ESD and other interferences, saves circuit space, optimizes user circuit scheme design, employs epoxy resin for filling and fixing, enables a product to have good mechanical strength and sealingperformance, can satisfy vibration, impact, sealing, moisture resistance, salt spray and other test conditions, and has high reliability, safety and environmental adaptability.

Description

technical field [0001] The invention belongs to the technical field of data transmission devices in mobile communication equipment, and more specifically relates to a data transmission module with a protection function. Background technique [0002] For the data transmission modules currently on the market, the industry practice is to simply provide an isolation transformer. As for the surge, overvoltage, ESD interference, etc. that may occur in the circuit, other related electronic components are designed separately in the hardware circuit. , so that the components integrated on the circuit board are dense and the circuit is complicated, which increases the difficulty of circuit design, and at the same time, the space utilization rate of the data transmission module is not high. Contents of the invention [0003] In order to overcome the above technical problems, the present invention proposes a data transmission module with protection function, which can cope with interf...
