An extendible electrical socket includes: a mother socket connected to a power supply source; and a plurality of daughter sockets which are connectable with one another to be an extendible electrical socket adapted for simultaneously connecting a plurality of electrical devices; each daughter socket including a locking device to be safely engaged with the mother socket or engaged with another or neighboring daughter socket to prevent from their disconnection when coupled and locked by each locking device.

A power station includes a wedge-shaped body including first and second surfaces extending between respective first and second ends. The respective first ends meet with the respective second ends being spaced apart in a rest position. The first and second surfaces are biased apart from each other such that an outward force is generated thereby when urged together from the rest position. At least one power socket is located on the wedge-shaped body and configured for connection to an electrical power source.

A coaxial tap in a hybrid fiber coaxial cable distribution system serves subscribers with an RF signal.

A standing structure for a shell of an extension cord is provided. Intercalating trenches are disposed on rear edges of a pair of opposite surfaces of the shell of the extension cord. A support frame includes a horizontally-disposed bottom plate and a vertically-disposed support plate connecting the bottom plate and having two intercalating strips intercalated into the intercalating trenches. Thus, the shell of the extension cord can be combined with the support frame to form the standing structure. The planar surface, not combined with the shell of the extension cord, of the support plate thus can face to a user for hiding power outlets and power cables plugged into the power outlets.

The panel (220), the energy-saving switch (230), and the connector (240) may be formed in a separable module type corresponding to each of the power sockets (130). The separable module type increases usability, because it is possible to use the modules only for necessary ones of the plugs (P) in the power sockets (130) and not to insert them into the power sockets (130) without a plug (P) connected.

In a connector unit including a connector and a connector cover that fits on the connector, the connector includes a guide means that guides electric wires in one direction, while the connector cover includes a pressing means that presses on and deforms the guide means so as to restrict the movement of the electric wires that are guided by the guide means, whereby the electric wires that are pulled out of the connector are oriented in the one direction in which the electric wires are guided by the guide means.

A multiple socket outlet (100) for an electrically adjustable table system is provided with a power supply unit (50) for the provision of a DC supply voltage for the table system from a mains AC voltage. The multiple socket outlet (100) forms an integrated unit together with the power supply unit (50).

Power socket extension lead

An extension lead having a body provided with at least one power socket area for receiving connecting plugs of the “Schuko” type, and having inside it electrical connection means, and a cable for connecting to the electrical power network with a connecting plug at its end that exits from the said body, characterised in that the body has externally two flexible covers, one upper cover and one lower cover, which form an internal cavity that encircles the said body and allows the electrical power network connecting cable to be housed in wound form.

A power strip having two or more powers strips daisy chained together where each of the two or more power strips include a sequence control module operable to sequentially activate and/or deactivate the outlets, thereby powering up or powering down each outlet separately across the two or more power strips. A pre-determined time delay, that can be set by a user, occurs between the activation and/or deactivation of the outlets. The sequence control module of each power strip is operatively coupled to the sequence control module of the subsequent next power strip so that one power strip can be used to trigger activation of the next power strip.

The invention is applicable to the technical field of electronics, and provides a jump wire-free patch board comprising a patch board body and a power line. The patch board body comprises at least a switch module, a power supply conversion device, a jack module, an elastic metal sheet assembly and a protection module. All components of the patch board body are integrally packaged on a circuit board, the protection module comprises an overload protection switch and a lightning protection and anti-surge device, the power supply conversion device comprises at least one of a high voltage AC output terminal and/or a low voltage DC output terminal, and the protection module is electrically connected to the high voltage AC output terminal and/or the low voltage DC output terminal through the elastic metal sheet assembly. Whereby, the invention realizes a more safe connection structure without jump wire.
