Abstract

Associable coupling connector for each of the storage relays of a sequential automatic device. The coupling connector comprises on the one hand the pins placed at the back of sockets which are assembled in three different areas of the front face, allotted respectively to the relay, to the input signals and to the output signals and, on the other hand, transversal conductors and transversal terminals to receive and transmit the voltage from the supply and the return to zero signal and respectively to transmit the sequential signals from the coupling connectors to the next ones.

Dependent claims

A sequential automatic control device for controlling electrical apparatuses which provide feedback signals upon completion of an operation, said control device comprising a plurality of mechanically coupled and electrically interconnected modules, electrical circuit means providing electrical supply and resetting signals to the modules;

sequence circuit means connecting each module to each adjacent module and adapted to transmit setting signals from each module to the next module and resetting signals from each module to the preceding module, each module consisting of an insulating housing having a back face provided with means for securing the respective modules to a common supporting member, a front face opposite to the back face and first and second side faces substantially parallel to each other, the first side face of each module cooperating with the second side face of an adjacent module, said front face having first, second and third surface portions, input terminals projecting through the bottoms of outwardly opening sockets arranged on the first surface portion, connecting terminals projecting through the bottoms of outwardly opening sockets arranged on the second surface portion, output terminals projecting through the bottoms of outwardly opening sockets arranged on the third surface portion, said output terminals being connected to the said apparatuses, and said input terminals receiving the said feedback signals, a storage relay unit mechanically coupled in a removable manner to each module, said storage relay unit having a plurality of terminals which are electrically connected in a removable manner to said connecting terminals of the modules, first and second recesses in said first side face and first and second projections on said second side face, each first recess being adapted to receive the first projection of an adjacent module and each second recess being adapted to receive the second projection of an adjacent module;
a plurality of transverse conductors within each module, said transverse conductors each having first and second terminals, the said first terminals in each module being adapted for electrical coupling with the second terminals of an adjacent module when said first projections are lodged into said first recesses, to complete the said electrical circuit means, first and second further terminals, the first further terminals in each module being adapted for electrical coupling with the second further terminals of an adjacent module when said second projections are lodged into said second recesses, to complete the said sequence circuit means;
and interconnecting means, lodged within the module housing, for connecting the said connecting terminals to the said electrical circuit means, to the said sequence circuit means and to said input and output terminals.

Dependencies are inferred from the claim text.
