DEFINITION

Classification: 439/349

Toroidal band urged radially of connection or adapted to be compressed for retention, e.g.., O-ring:

(under subclass 345) Coupling part wherein the means to maintain electrical connection has the shape of a tube curved upon itself into a ring and is adapted to function for maintaining interengagement by being resiliently urged toward or away from the center of the ring or by being resiliently urged toward the center of the tubular configuration.

(1) Note. The "tube" of this subclass may be circular or

rectangular, but must be of such configuration that force on one part is transmitted to other parts of the tubular cross-section, as compared to a sleeve wherein one portion can be forced to move without affecting other portions.

252, for a self-aligning contact formed in a tubular configuration biased towards its axis by a contractile band.
