Electrical assemblies

Claim 1

An electrical assembly for making connection with a plurality of pin elements, the assembly comprising: a ground plane member, a plurality of socket members, and means mounting each socket member with and extending through the ground plane member, each socket member being shaped to receive a respective one the pine elements, each socket member including within it capacitor means, an inductive element, and a plurality of spring wire elements disposed around the socket member and extending obliquely of the axis of the socket member, the spring wire elements making resilient sliding contact around a surface of a respective pin element inserted in the socket member at least at opposite ends of the socket member, and the spring wire elements making electrical contact with opposite ends of the capacitor means, the ground plane member making electrical connection with the capacitor means intermediate its ends so as to form two capacitor elements of a π filter circuit, the inductive element being located between opposite ends of the capacitor means, and each pin element being so shaped that it can be slid into and out of the assembly without disturbing others of the pin elements.
