摘要

A contact block has a plurality of contact units each formed by two U-shaped strips inserted one inside the other. The strips have base portions connected with one another and with a support member by rivets. Each strip has two lateral portions each provided with a slot extending over a part of the length thereof so as to form two resilient tongues in each lateral portion. Thereby, each contact unit has eight tongues forming four contacts. The contacts are separated from one another by a grid of insulating material.
