Communication interface device

Abstract

The invention discloses a communication interface device. The communication interface device comprises a front panel, a rear panel, a frame, a fixed support and a protective circuit positioned insidethe fixed support, wherein the fixed support is of a stepped rectangular structure, and an opening is formed in one end of the stepped rectangular structure; the front panel is arranged at the openingend of the fixed support; the frame is arranged on the peripheries of the front panel and the fixed support, and is used for fixing the front panel; the rear panel is arranged inside the fixed support, and the front panel and the rear panel are connected through the protective circuit; the front panel is provided with a plurality of signal wire interfaces including covered wires, magnets, internet accesses, radio frequency ports, video ports and power supply ports; communication equipment outside a vehicle is connected into the communication interface device through the signal line interfaceson the front panel; the rear panel is provided with signal wire interfaces corresponding to the front panel, and communication equipment inside the vehicle is connected with the communication interface device through the signal wire interfaces on the rear panel. According to the communication interface device, protective treatment can be carried out in a targeted manner according to the characteristics of different transmission signals, and the device is multiple in functions and small in equipment volume.

Description

technical field [0001] The invention belongs to the technical field of vehicle command communication, and more specifically relates to a communication interface device. Background technique [0002] Inductive lightning strikes intrude into equipment through the lines that transmit information outdoors, causing damage to electronic equipment that is serially connected in the middle or at the end of the lines. According to the lightning protection principles of electronic equipment recorded in the lightning strike test method standard for electronic equipment, when engaging in the design and production of electronic equipment, considering factors such as equipment quality, cost, and personal safety of operators, the lightning impact generated on electronic equipment must be limited. To the allowable range of equipment, in order to meet the technical requirements stipulated in the standard, this standard is also applicable to the anti-sensing lightning protection of electronic ...
