Background

On a traditional CPCI board card, all the sockets are through-hole plug-in components, the sockets are arranged according to pin hole positions of the sockets on the CPCI board card, and the welding surfaces of the CPCI board card are welded or crimped by soldering irons, so that the electrical connection and the mechanical connection between the sockets and the CPCI board card are realized. In recent years, circuit designers have adopted a computer bus jack, i.e., a CPCI jack. The socket pins of the packaging type are high in density and troublesome to insert and pull, a plurality of CPCI board cards are in a debugging stage, complicated inserting and pulling actions are not convenient, and meanwhile after irreversible problems are found in debugging, the board cards are scrapped along with the CPCI connector, so that the burden is increased on the product cost.

As shown in fig. 1, the 3UCPCI board has 6 rows of pins, the row pitch is 2mm, and the row pitch is 2mm, so that the pins are more and dense, and even the solder socket is difficult to disassemble, the pins are easily damaged, and the CPCI socket is easily damaged.

As can be seen from fig. 2, in the welding type, socket pins need to be inserted into the metal holes of the board card for welding; in the crimping type, the socket is pushed into the metal hole of the board card under the action of external force, so that the pins of the socket are forced to generate elastic deformation, the pins are pressed into the metalized mounting holes of the printed board, and the socket and the printed board are electrically and mechanically connected by virtue of the elastic contact pressure of the pins of the socket.
