DEFINITION

Classification: 439/613

Connector of the type having only concentric annular contacts or annular contact disposed concentrically about an axial contact:

(under subclass 611) Electrical connector wherein the glasslike body carries a connector of the type having at least two contacts* which are spaced-apart and electrically insulated one from the other the connector forming a coupling part* specially adapted to mate or interengage with a complementary plural-contact-carrying counterpart*, so that a readily separable electrical joint having at least two mutually-insulated electrical paths may be formed, and wherein one of the contacts is disposed symmetrically around and spaced from the longitudinal axis along which the coupling part is intended to be engaged and coupled with its counterpart, all points on the symmetrical contact at any point along said axis being equally spaced from said axis, and wherein the outer of the contacts is either (a) disposed on the longitudinal axis along which the coupling part is intended to be engaged and coupled with its counterpart or (b) also disposed symmetrically around and spaced from the said longitudinal axis in such a manner that all points on the second said symmetrical contact at any point along said axis is equally spaced from said axis a distance different from the corresponding contact-to-axis points on the first said symmetrical contact, whereby the symmetry of the contacts of the coupling part is such that the contacts will make electrical connection with their mating counter-contacts* regardless of the angular disposition of the coupling part about the longitudinal axis of engagement with its counterpart.

(1) Note. Included also in this and the indented subclasses are patents in which the connector carried by the glasslike body is disclosed to be of the type defined above, but in which the claims recite only one of the contacts.

coupling part having at least one annular contact disposed concentrically around the longitudinal axis of engagement with its counterpart, such coupling part usually having an axial contact or another annular contact coaxial with the longitudinal axis.
