Abstract

The invention discloses a waterproof sealing structure design method of vehicle-mounted electronic equipment, which relates to the technical field of waterproof sealing. The input / output interface socket is a separated structure, comprising a shell sealing connector and an on-board socket connector. The integral seal between the upper shell and the lower shell is carried out through the forming seal ring, and the dimensions of the forming seal ring and the sealing groove are obtained through calculation, and the allowable manufacturing tolerances are calculated according to the tolerance compensation mode. The waterproof sealing design method of the vehicle-mounted electronic equipment is convenient for the installation, disassembly and maintenance of the whole machine wire harness, solvesthe problem that the board-mounted socket connector needs to be welded many times, improves the reliability and heat consumption of the large current input and output application, reduces the manufacturing and installation positioning process precision requirements, and realizes low-cost installation.

Description

technical field [0001] The invention relates to the technical field of waterproof sealing, in particular to a method for designing a waterproof sealing structure of vehicle-mounted electronic equipment. Background technique [0002] As the functional requirements of on-board electronic equipment become more and more complex and powerful, the tight space in the car can no longer fully satisfy the installation of electronic equipment in the trunk. Due to the volume, weight, heat dissipation and interconnection with other equipment, high-power electronic equipment requires the equipment to be installed in the harsh working environment of the vehicle body. Therefore, the vehicle-mounted electronic equipment is required to have IP67 protection function, and the shell protection design should not only consider the upper and lower shells The sealing design should also consider the sealing design of the input and output interfaces. [0003] The IP67 protection design of the existin...
