DEFINITION

Classification: 439/578

INCLUDING OR FOR USE WITH COAXIAL CABLE:

(under the class definition) Electrical connector having one or more contacts* adapted to be either (a) electrically secured in one-to-one relationship to one or more conductors* of an elongated plural-conductor cable* or (b) electrically coupled to one or more contacts of a complementary mating connector, the contacts of which being securable in one-to-one relationship to one or more conductors of an elongated plural-conductor cable, the elongated cable having an inner conductor centrally disposed within the cable and extending along the longitudinal axis thereof and further having at least one tubular outer conductor concentrically surrounding and fixedly spaced apart from the inner conductor, and wherein the conductors of the cable are electrically insulated from one another.

(1) Note. The term "coaxial cable" is interpreted to encompass any form of coaxial transmission line having the defined coaxial configuration of conductors and may include,

for example, a cable having flexible coaxial conductors with flexible insulation interposed between the conductors or rigid conductors disposed in spaced coaxial relationship.

(2) Note. A connector of this and the indented subclasses usually has a contact configuration similar to the coaxial cables used therewith in that the connector often has an inner contact centrally disposed within the connector and has a tubular-shaped outer contact concentrically surrounding and fixedly spaced apart from the inner contact by means of an intermediate layer of insulation.

(3) Note. The inner, centrally-disposed conductor of the cable may also be tubular in cross-section, in which case the cable comprises inner and outer tubular conductors held in fixed spaced-apart concentric relation from one another.

(4) Note. The outer tubular conductor of a coaxial cable is often used as an electrostatic or inductive shield for the inner signal-carrying conductor (or conductors) or used as the common return or grounded line of an electrical circuit.

92+, particularly subclasses 98+ for an electrical connector having a specific provision to electrically connect a portion thereof to the earth for the purpose of providing a safety ground for the electrically connector. 274, 275 and 279, for an electrical connector, which may be of a coaxial cable type, combined with a distinct cable sheath sealing element or material.

394, for a coaxial-cable type electrical connector having a cutter-type electrical contact for piercing the insulative sheath of a coaxial cable.

607+, for an electrical connector adapted to be electrically connected to a conductor or cable other than a coaxial cable and which provides electrostatic or inductive shielding or internally disposed contacts, and see Note (1) appended to subclass 607.
