[0002] CPCI is the abbreviation of Compact PCI, which is a high-performance industrial computer bus standard proposed by the International Industrial Computer Manufacturers Association in 1994. The electronic equipment chassis is the shell of the electronic equipment, which mainly plays the role of installing, supporting, accommodating and protecting electronic components, circuit boards and electrical connectors, and protecting them from various environmental influences and interferences. It is the basic structure to ensure the realization of electrical performance.

[0003] Chinese utility model patent (authorization announcement number: CN207424771U A reinforced chassis for integrated measurement and control equipment based on CPCI architecture) The chassis is rigidly connected to the upper cover, front panel, side panel, rear cover, upper air duct cover and lower air duct cover. The components connected to the chassis are made of high-strength aluminum alloy, and the upper cover, front panel, side panel, rear cover, upper air duct cover and lower air duct cover are all processed as a whole. The chassis is welded after overall processing, and has high structural rigidity and durability. The external connector of the chassis is electrically connected to the backplane through the CPCS module and the TRM connector. The external connector adopts a floating connector to eliminate the stress and poor contact of the connector caused by processing and assembly errors. The wire spring contact pair with low contact force is used to solve the connection problem of high-density multi-core TRM sockets and matching TRM plugs. The functional module adopts a standard CPCI design to achieve cable-free installation inside the whole machine, greatly improving the reliability and maintainability of the whole machine.
