Abstract
A drain ground structure for use with telephone connector blocks interconnecting shielded conductor pairs in installations requiring maximum noise and induced current suppression. The structure includes an elongated coil spring capable of frictional engagement with the ground wire of the shielded conductor cable between adjacent convolutions. To prevent the development of induced current in the spring itself, a metallic shorting bar is positioned parallel to the axis of the spring, the bar having lanced tabs which extend laterally from the plane of the bar and are engaged between the convolutions of the spring at periodic intervals.
