Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
196 words
A system for assembling and connecting electrical apparatus on frame works comprising an assembly frame, a plurality of connection plinths module-determined in size on the assembly frame, each plinth comprising a lower part and said upper part having holes therein arranged in pairs in rows constituting means to receive contact members inserted in the plinth from the lower side and from the upper side, each pair of holes in the upper part being situated opposite a corresponding pair of holes in the lower part, said lower part being provided with enclosure means forming a hollow opposite each pair of holes in the lower part, a connection element in each of said hollows, each connection element having a pair of resilient tongues, each connection element being arranged opposite two holes in the lower part and constituting an engaging and holding member for a contact member inserted in the plinth from the bottom side, a number of flexible connection members, each connection member comprising an electrical conductor provided with a contact element at each of its ends, said resilient tongues and said contact elements having cooperating means thereon for releasably holding to said contact elements in the holes.
Claim 2
Independent Claim
196 words
A system for assembling and connecting electrical apparatus on frame works comprising an assembly frame, a plurality of connection plinths module-determined in size on the assembly frame, each plinth comprising a lower part and said upper part having holes therein arranged in pairs in rows constituting means to receive contact members inserted in the plinth from the lower side and from the upper side, each pair of holes in the upper part being situated opposite a corresponding pair of holes in the lower part, said lower part being provided with enclosure means forming a hollow opposite each pair of holes in the lower part, a connection element in each of said hollows, each connection element having a pair of resilient tongues, each connection element being arranged opposite two holes in the lower part and constituting an engaging and holding member for a contact member inserted in the plinth from the bottom side, a number of flexible connection members, each connection member comprising an electrical conductor provided with a contact element at each of its ends, said resilient tongues and said contact elements having cooperating means thereon for releasably holding to said contact elements in the holes.
Claim 3
Dependent Claim
34 words
A system according to claim 1, in which the assembly frame is of rectangular shape, the length of the conductor of said connection member being at least equal to the diagonal of said frame.
Claim 4
Dependent Claim
40 words
