Abstract: An electric socket includes an electrically insulative bottom shell, two metal electrode clamps mounted inside the electrically insulative bottom shell, an electrically insulative top shell covering the electrically insulative bottom shell and having two bottom spacer ribs set between the two metal electrode clamps to keep them apart, and a sliding block slidably coupled to the electrically insulative top shell and movable between a locking position where a bottom protruding block of the sliding block pushes the free end of each spacer rib sideways against the front clamping strips of the metal electrode clamps, thereby causing the metal electrode clamps to be locked to the metal conducting blades of the inserted electric plug and an unlocking position where the bottom protruding block of the sliding block is released from the spacer ribs, thereby unlocking the meal electrode clamps from the metal conducting blades of the inserted electric plug.

Abstract: In some embodiments, the present invention provides an independently tightening collet surrounding each socket for each of a plurality of corresponding high-electrical-power prongs, wherein the collet is loosened for normal (low-insertion-force) insertion and withdrawal of the plug from the outlet. Once the plug is inserted, the collet is tightened, providing a high-contact force to lower the contact resistance and to help keep the plug from coming unplugged. In some embodiments, the plug is not “locked”, in that a tension force pulling on the plug will overcome the contact force at a point before the plug or outlet is damaged, and the plug is allowed to come unplugged. In some embodiments, engaging the collet will also provide a wiping or sliding motion between the prong and socket for each connection, thus wiping at least some dirt or corrosion away and providing a lower-resistance better electrical contact.

The female receptacle and male plug of the device can be separated by a cord to create an extension cord. The female receptacle or male plug could also be placed on the cords of a tool or appliance. A plurality of female receptacles could be used in a single unit to create a power strip having locking receptacles.

Abstract: A locking electrical plug 1 includes a plug body 8 and a securement arm 18 residing in a securement arm slot 32 located in the flat of a power blade 16. The securement arm 18 is normally biased orthogonal to the flat of the power blade 16 by a biasing member 20. The securement arm 18 includes a securing nib 25 capable of mating with the biasing member 20. In the normal locked position, the securing nib 25 is not mated with the biasing member 20 causing the securement arm 18 to extend orthogonally outward from the securement arm slot 32. When the securement arm 18 is slid along the major axis of the power blade 16 towards the unlocked position, the biasing member 20 and the securing nib 25 mate such that the securement arm 18 lies in the flat of the power blade 16. A shaft 14 is positioned in the plug body 8 and allows a user to control the locked/unlocked characteristics of the locking electrical plug 1. In one embodiment a spring 15 acts to position the securement arm 18 in the normal locked position.

Abstract: A lock releasing mechanism of a connector in which connector terminals are received in terminal receiving chambers respectively in a manner that tongue pieces of the connector terminals are in opposition to each other, and a wiring groove is provided in the outside of the terminal receiving chambers so that all of electric wires connected to the connector terminals are laid in the same direction, whereby the connector terminals can be made the same with each other in configuration to thereby reduce the cost. Further, by pushing a single lock releasing member, lock releasing levers are moved to thereby simultaneously urge the tongue pieces of the connector terminals in opposition to each other to release the connector terminals in a lump from locking with partner-side connection terminals, whereby the workability in maintenance can be improved.

Abstract: A locking, non-catching electrical cord has smoothly rounded edges so as not to catch on foreign objects. The male prongs of the extension cord taper from the end of the cord to a rounded end of the same height, and the prong receptacles are shaped to fit the male prongs, so as to allow the prongs to snap-fit into the receptacles. Alternatively, the prong receptacles may have two cavities skewed from one another, and the male prong end of the cord may be twisted once situated within the prong receptacle to create a locking fit.

Abstract: An apparatus for handling the removal of a memory card from a computer system. The apparatus includes a socket for receiving the memory card having a first section of card detect pins and a second section of single pins. The second section is aligned with the first section during insertion of the card into the socket. The second section slides out with the card during removal of the card from the socket. The apparatus also includes an interrupt handler for transferring control to the interrupt handler upon a break in contact between the card and card detect pins in the socket. The interrupt handler disables signal lines connected to the signal pins before the second section begins pulling out from the card upon removal of the card from the socket.

Abstract: A safety electrical outlet is disclosed which uses a covered outlet box in which the electrical contacts are on the back of the cover, and cannot easily be reached by a person (especially a child) poking into the socket. The contacts in turn form a portion of a circuit with electrically conductive leads and risers from the ordinary business power conduits. The corresponding plug has retractable contact prongs or blades which extend out from the sides of the plug, so that when the plug is inserted into the socket, the sideways-extending blades touch the contacts on the underside of the cover plate and the electrical connection is completed. When it is desired to disengage the plug, the blades are retracted and the plug removed from the socket. Built-in spring-loaded panels cover the plug openings in the cover plate when the plugs are not inserted. There may be a single socket/opening in the cover or there may be two or more ganged openings/sockets.

Abstract: The connector includes a body, a resilient locking arm provided on the body and with a locking projection at its free end which engages in a connection hole in a panel to lock the connector to the panel, and a lock-up detector. The lock-up detector is provided in a preliminarily engaged state between the locking arm and the body prior to the fitting of the connector to the panel with a length thereof protruded more than the locking projection. When the connector is completely locked to the panel, the lock-up detector is released from the preliminarily engaged state and becomes insertable by a push from the opposite side of the panel to the connector. This enables confirmation of whether a connector attached to the end of a wire harness is completely fitted to a panel, e.g., at a door portion of an automobile from outside the panel and improves the reliability of a connector as a product.

Abstract: An electrical plug for 3-wire line cords includes a plug body having a U-shaped grounding pin. A rise pin is disposed between opposing walls of the U-shaped grounding pin. A locking element extending through the plug body includes a threaded proximal portion and a flat distal portion, the distal portion having a ramp disposed over the rise pin and a serrate edge opposite the ramp with the distal portion disposed within the grounding pin opposing walls. A locking knob is threaded onto the proximal portion. With the plug in an outlet, the knob is rotated clockwise to draw the flat distal portion rearward causing the ramp to ride up the rise pin and to cause the serrate edge to grip the inner surfaces of the grounding socket. Rotating the knob counterclockwise releases the serrate edge to permit withdrawal of the plug from the outlet.
