DEFINITION

Classification: 439/815

Screw or nut moves resilient or resiliently biased securing part:

(under subclass 801) Electrical connector including an elastic body which tends to return to its normal shape after being distorted and wherein the screw-threaded member to be rotated distorts the elastic body whenever it is rotated to clamp a conductor.

(1) Note. If the screw or nut is to be rotated with the bias of the resilient body to clamp a conductor, the resilient body usually provides part of or the initial clamping pressure while the screw or nut serves to lock the connector in its clamping condition or to increase the clamping pressure. If, on the other hand, the screw or nut is to be rotated against the bias of the resilient body to clamp a conductor, the screw or nut provides the clamping pressure while the resilient body usually serves to facilitate release of a previously clamped conductor or to hinder the screw or nut from becoming inadvertently unscrewed from its clamping condition.
