  • Connector system for a race equipment
    Patent number: 4062611
    Abstract: In a rack mounted electrical equipment modules, for example, printed circuit cards are plugged into connectors arranged on the back plate of a shelf. Several shelves are mounted in a rack and are interconnected by cables mounted in the rack. In order to dispense with the connectors normally used to interconnect the shelves with the cables the back plate connectors are provided with a fixed part and a detachable part. The fixed part is used for the internal wiring of the shelf and the detachable part is connected to the cable. When the shelf is mounted in the rack the detachable part is snapped into the connector.
