Abstract: An electrical receptacle is provided herein which has a special locking mechanism preventing the plug from falling off. The receptacle mainly contains a body housed inside a sleeve. The body has at least a locking blade with a bended portion extended out of the body and pressed against the inside of the sleeve. A slot opening on the bended portion is roughly aligned with the slot of the body. When the prong of a plug is inserted into the sleeve, the sleeve presses the bended portion so that the slot opening and the slot on the body are completely aligned and the prong could go all the way into the slot of the body. The bended portion of the locking blade then springs back to a slant position to lock the prong. To unplug, the pulling force applied to the plug drags the body toward the sleeve which again presses the bended portion of the locking blade so that the prong could be pulled out of the slot of the body easily.

The cantilever has a concave portion (206) near a free end thereof. When the CPU with a multiplicity of solder balls is attached onto the connector, the concave portions of the terminals cover bottom portions of the solder balls. Therefore, the terminals of the connector electrically connect with the solder balls of the CPU steadily, and a reliable connection between the CPU and the PCB is established.

In the second position, the second blocking surface blocks at least a portion of the second insertion path, but the first blocking surface clears the first insertion path. Thus the connector assembly may receive plugs in either the first or the second socket, but not in both sockets simultaneously.

With the blade stabilizer held in a pre-staged position, the distal ends of the blades are protected from being inadvertently knocked and bent which would cause misalignment. Furthermore, the stabilizer prevents entry of debris into the chamber of the male connector which would hinder or prevent full mating of the electrical connector.

Abstract: A blocking outlet and corresponding locking plug provide a completely enclosed safety electrical connection system for supplying electrical power from a wall fixture. The blocking outlet installs in a conventional wall-mounted electrical box, providing access to building electrical wiring. The outlet has receptacles that retain spring-loaded covers, which have a closed position generally flush with the front side of the face plate. The springs provide sufficient tension to the covers to block small children from inserting fingers or foreign objects into a receptacle, preventing inadvertent exposure to hazardous voltage.

Small access apertures in the interior of an outlet receptacle contain recessed contacts.

Abstract: A ceiling fan or light fixture is provided with a sliding support member that slides horizontally into a support channel attached to a ceiling box. An electrical plug and receptacle attached to the two support members automatically mate as the two support members are slid together. A bell is then raised to cover the two support members and prevent them from sliding apart. The sliding support member is held above the bell by telescopic standoffs with a frictional action. A screw is captive within each standoff. As the bell is raised, the part of each standoff fixed to the bell slides upwards until its upper end positions the tip of the screw just in front of a threaded hole in the fixed support channel. Fastening the screws into the threaded holes then both locks the sliding mechanism and attaches the bell directly to the fixed support channel.
