ABSTRACT:
In a cabinet for electrical or electronic equipment, of the type in which the components of the equipment are mounted on vertically disposed printed circuit boards carried by supports movable on slides within a metal casing so that the supports can be easily withdrawn from the casing, the usual rigid drawer forming the support is replaced by a horizontally disposed printed circuit board movable in slides in the casing which also form connectors making electrical connection with conducting tracks on the horizontal printed circuit board. The horizontal board also carries a set of similar connectors to receive the vertically disposed printed circuit boards. The connectors are of the type whose contacts can be held open during insertion or extraction of a printed circuit board so that zero force is required for insertion or extraction.
