Description

Technical Field

[0001] The utility model relates to the technical field of CPCI chassis, in particular to a CPCI chassis which is convenient to assemble and disassemble. Background Art

[0002] CPCI bus is a high-performance industrial computer bus standard proposed by the PCII Industrial Computer Manufacturer's Group in 1994. Compact PCI is an industrial version of the standard PCI bus, using the shock-resistant Eurocard package. The jack connector is designed to be loaded into the rack-mounted system from the front. The computer telephony industry, guided by PICMG, has expanded the CompactPCI system architecture to support analog and digital telephone connectors.

[0003] However, in the current use of CPCI chassis, there are problems such as short service life, great difficulty in maintenance and long maintenance cycle. This is because there are a large number of wires, power supplies and circuit boards inside the CPCI chassis. Once a short circuit or other problems occur in a certain part, it is impossible to determine the problem from the outside for maintenance. At this time, it is necessary to disassemble the processing unit inside the chassis to determine the cause of the failure. The existing processing unit is generally installed inside the chassis by bolts. Therefore, when disassembling the processing unit, it is necessary to use a disassembly tool such as a screwdriver to disassemble each bolt in turn, which is time-consuming and labor-intensive and affects the maintenance speed. Therefore, a CPCI chassis that can be quickly disassembled and assembled is urgently needed. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the processing unit in the chassis cannot be quickly installed and disassembled, which affects the maintenance speed of the chassis, and proposes a CPCI chassis which is convenient to install and disassemble.
