Abstract
Abstract A direct-current supply connector is disclosed comprising at least one pair of terminals for providing electrical connection between, on the one side of said connector an elongated flat module provided on the inside with low-inductance direct-current supply lines and, on the other side of said connector a module rack for receiving a plurality of said elongated modules. The module rack is connected with each of said modules over one of the connectors, current being supplied from said module rack to said module. A first individual pair section of said terminal pair which is connected to an outgoing line of the direct-current supply is connected with a second pair section of said terminal pair which is connected to a return line of the direct-current supply over a shunt capacitor disposed in the immediate vicinity of said connector thereby reducing interaction between elements in modules connected to one rack. The shunt capacitor may be located in the module rack or the module. It may be sized and connected to provide impedance matching between rack and module.

Claim 1
Independent Claim
146 words
A direct-current supply connector comprising a plurality of pairs of terminals for providing electrical connection between, on the one side of said connector an elongated flat module (2) provided with a low-inductance direct-current supply line and, on the other side of said connector a module rack for receiving a plurality of said elongated modules, said module rack being connected with each of said modules over one of said connectors, current being supplied from said direct current supply linE of said module rack to said module, wherein a first individual pair section of each of said terminal pairs which is connected to an outgoing line of said direct-current supply line is connected with a second pair section of said each terminal pair which is connected to a return line of the direct-current supply over a shunt capacitor disposed in the immediate vicinity of said each terminal pair.
Claim 2
Dependent Claim
146 words
A direct-current supply connector comprising a plurality of pairs of terminals for providing electrical connection between, on the one side of said connector an elongated flat module (2) provided with a low-inductance direct-current supply line and, on the other side of said connector a module rack for receiving a plurality of said elongated modules, said module rack being connected with each of said modules over one of said connectors, current being supplied from said direct current supply linE of said module rack to said module, wherein a first individual pair section of each of said terminal pairs which is connected to an outgoing line of said direct-current supply line is connected with a second pair section of said each terminal pair which is connected to a return line of the direct-current supply over a shunt capacitor disposed in the immediate vicinity of said each terminal pair.
