Background

CPCI (compact Peripheral Component interconnect), a unified new bus and interface standard that is intended to fully replace CPCI and AGP and eventually implement the bus standard. Its main advantage is high data transmission rate and considerable development potential.

In the aspect of mechanical structure, the connectors used by the CPCI bus structure adopt pin hole connectors with the density of 2mm, and the plugging force is moderate. Most CPCI reinforced modules are not provided with an insertion assisting mechanism, and the modules can be easily pulled out only through the pulling-out devices on the left side and the right side.

Compared with the CPCI plug-in module, the CPEX plug-in module uses a large number of reed connectors, so that the plugging force is large. In addition to the need to separate and extract the plug by means of a special device, i.e. the extraction aid, the plug must also be made possible by the interaction of the extraction aid with the insertion aid during the insertion process.
