Electrical receptacle
First Claim
1. A duplex electrical receptacle, comprising:
- a housing having a base and a cover releaseably secured to the base, said base and cover together defining an interior chamber, said base having a support surface and means for introducing electrical conductors into said chamber, said cover having a pair of spaced aperture means for admitting blade-type contacts of a plug into said chamber, and a pair of spaced slots in said cover associated with each said aperture means and extending between said chamber and an exterior surface of said housing;
a pair of blade-type electrical contact members disposed in said chamber, each said member having an elongated base adapted to be releasably secured to said support surface and electrically connected to an electrical conductor, an arm extending longitudinally from each end of said base, a flexible contact portion extending from each said arm and being longitudinally aligned with an aperture of one of said aperture means for electrically contacting a plug contact inserted through said aperture, a projection extending from a side surface of each said contact portion for interlockingly engaging an aperture in a plug contact, each said projection having having a locking surface extending substantially transversely of said side of said contact portion and a camming surface extending from said locking surface to said side at an angle thereto and toward a free end of said side, and a finger extending from said arm and outwardly of said chamber through one of said slots, said fingers being arranged to laterally displace said contact portions and release interlocking engagement between said contact portion and a plug contact upon movement of said fingers along said slots.

Abstract
The invention describes an electrical receptacle comprising a housing having apertures for receiving blade-type contacts of a plug in which the plug is formed with an aperture at its free end, and a pair of contacts secured in the interior of the housing in longitudinal alignment with the apertures for electrically conductively contacting plug contacts inserted through the apertures, each contact member having a flexible contact portion having a projection releasably interlockable with the aperture of a plug contact to prevent inadvertent withdrawal of the plug contacts from the housing and an arrangement for selectively manually displacing the contact portions for releasing the plug contacts.
