Abstract: A component (30) is to be attached by means of a plug connector (10) in a hole (53) of a base plate (50). To this end, the plug connector (10) has a shaft (15) with a flat profile. When the plug is inserted in the socket, the shaft end (20) projects out of the hole (53) on the rear side of the circuit board (52). The shaft end (20) is followed by a shaft section (13), broadened relative to the hole width (54), which has an opening (14). By means of the opening (14), the shaft section (13) is split into two legs (11, 12), which are sprung against each another and which hold the shaft (15) in the hole (53) of the circuit board (50) when the plug is inserted in the socket. To improve the holding effect, the two legs (11, 12) are constructed differently one from the other, wherein one leg (11) has a greater longitudinal extension (21) than the other (12). This means that the broadened shaft section (13) splits into a long (11) and a short leg (12).

Abstract: A water and/or airtight electrical socket for portable electronic devices includes sealing elements that are shaped like an arc, and arranged to seal only a portion of the perimeter of the socket-plug interface. When this arc element experiences pressure, it will mechanically relay the force caused by the pressure only to that section of the perimeter of the socket-plug interface that it is arranged to seal. It will not relay mechanical forces any further. This way, the mechanical effect of any extra asymmetric pressure will simply be limited to increasing the pressure of the seal in the perimeter section of that particular sealing element, thereby tightening the seal further still. This allows the socket opening to be sealed in a water- and/or airtight manner even in asymmetric pressure conditions, both when there is no plug in the socket and also when a plug is inside the socket.

When the charger is inserted into the hole and pushes the pivot cover, the pivot cover is disposed in an opened position and the slide cover is pushed until the charger is electrically connected to the power source.

Abstract: The invention relates to an electrical socket (110) that is water and/or airtight. In particular, the invention relates to a water and/or airtight electrical socket (110) for portable electronic devices (500).

Abstract: Improvements to a 3-way light bulb socket are shown. The major improvement is to replace or complement the rigid middle contact element of the socket with an elastic/flexible contact spring. The 3-way light bulb has a solder blob on its middle contact ring, where said blob usually has a rough, uneven surface, and frequently does protrude beyond the general surface of the bulb middle contact ring. The solder blob interferes with the conventional socket middle contact element, which is rigid, and prevents the system from creating a good, permanent and reliable electrical connection between the socket and the bulb. Potential flicker and discomfort to the user can occur as a result. Also, the operating life of the bulb as well as the power consumption can be affected. The proposed flexible middle contact spring can alleviate most of these problems.

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.

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.

Abstract: An extractable conversion plug with a safety protection means includes a spring is located between a moveable pillar of a slab and a latching element, inside a connection head, such that the slab can cover conduction pieces through an elastic force from an expansion of the spring, thereby preventing the conduction pieces from being exposed. Upon emplacing the connection head at a base seat, the slab is stopped from moving by a stopper, and the conduction pieces are exposed and are contacted with spring leaves of the base seat, thereby constituting a close-circuit status. When the base seat falls off by accident, a stopping force of the slab is relieved to release a compression force from the spring, which will cause the spring to expand, so as to move the slab to cover the conduction pieces, thereby preventing from getting an electric shock by a careless touch.
