Abstract

1390472 Electric couplings KENTROX INDUSTRIES Inc 12 June 1973 [14 June 1972] 27928/73 Heading H2E [Also in Division H1] An attenuator pad comprises a substrate 30 with pairs of conductors 32, 34 thereon, each pair of conductors having a resistor connected therebetween, as shown, the conductors terminating at one edge of the substrate so as to form contacts to a connector 24, the substrate and resistors being housed in a hollow case 28 with an insulating filling 44, said one edge of the substrate extending from the case. The connector 24 includes resilient conductors 50, 52 making contact to the conductors 32, 34, the resilient conductors having fixed resistors, 10, attached thereto to determine the attenuation network.
