Abstract:
A system for assembling and connecting electrical apparatus such as relays, supervision panels, circuit cards and electrode connections, multipole contacts and the like includes cabinets having frameworks fixed or pivoted in them. Assembly frames attached to the framework carry a number of connection plinths, module determined in size, having holes arranged in pairs in rows to receive contact sockets from one side of the plinth and contact pins for direct engagement in the sockets from the other side. The pins are held in the sockets by connecting elements provided with resilient tongues arranged in recesses inside the plinth. The connection elements are common to a pair of holes, and are provided with openings in their legs which are engageable over projections on the contact pins.
