DEFINITION

Classification: 439/558

Including lamp or electron tube socket:

(under subclass 557) Coupling part particularly adapted to detachably receive and electronically couple to a member intended to radiate light, or to a member including electrical amplifying or switching means utilizing an environment excluding, vacuum envelope.

SEE OR SEARCH THIS CLASS, SUBCLASS:

56+, for a preformed panel circuit arrangement with an electrical for connection to a lamp or electron tube.

168, for a lamp or electron tube socket or base convertible by internal change to selectively cooperate with a different contact.

220, for a lamp or electron tube socket or base adapted to engage a mating connector in alternative manners.

226+, for a coupling part to receive a fluorescent or neon lamp.

280, for a lamp or electron tube socket or base having a resilient housing for sealing with a coupled connector. 336, for a lamp or electron tube socket adapted to receive a cooperating lamp or tube by bayonet action, including a movement-actuating means or retaining means in addition to the contact of the socket.

356, for a lamp or electron tube socket including a retaining means comprising a finger or stretchable sleeve resiliently urged laterally of connection with a mating part.

375, for a lamp or electron tube socket or base with a guiding means for mating of a coupling part.

414, for a lamp to electron tube socket or base including a conductor sheath penetrating contact and screw means to move the conductor against the cutting contact.

419, for a lamp or electron tube socket or base including a conductor sheath penetrating contact adapted to cut to engage a first conductor and to also engage (and interconnect) a second conductor.

541, for plural lamp or electron tube sockets including supporting means therefor.

602, for a lamp or electron tube socket or base including flexing insulation.

611+, for a connector or contact having vitreous-type envelope secured thereto (e.g.., a base of a lamp or vacuum tube).

661+, for a plural contact coupling part including a screw-threaded contact and insulation other than the conductor sheath.
