Problems solved by technology
The problem with these power supplies is that when the power supply is plugged into the input supply and left there, energy is dissipated, although the power is low, but because the power supply is often left there for long periods of time, energy is consumed. neglected energy
For example, a mobile phone charger is permanently connected to the power grid and is used to charge a mobile phone during a few hours a week, consuming standby power the rest of the time
Therefore, the question is how to reduce the energy consumption in power supply equipment

Embodiment Construction
[0026] In this context, the term "connector" is used to refer to an assembly of functional elements that form both a mechanical and electrical connection, while the term "contact" (noun) is used to refer to a functional element that provides a specific electrical connection, such as a Pins, pads, balls, fingers, etc.
[0027] Figure 1a A connector 100 of a power supply according to an embodiment of the present invention is illustrated. The connector includes electrical contacts 101 for providing electrical contact with mating contacts (not shown). Figure 1a A connector is shown having a first part 102 arranged so that the user can grip the part 102 when connecting and disconnecting the connector so that power is to be supplied due to the applied power for plugging the connector The force of powering the connected device for mating and unplugging the connector from the device causes the first part 102 to slide relative to the second part 104 , the sliding being defined by the...

A connector for an electric power supply device is disclosed. The connector is arranged to mate a corresponding connector at an apparatus to which the electrical power supply device is arranged to supply electrical power, wherein the connector comprises at least one electrical contact; a housing having a first part arranged grippable by a user when the user connects or disconnects the connector to the device, and a second part slidably arranged with the first part; at least one electrical contact arranged on one of said first or second part, wherein a first force for connecting the at least one electrical contact to the corresponding mating connector is higher than a second force for causing sliding between said first and second parts; and a switch arranged to be actuated based upon relative positions of said first and second parts, wherein said switch is arranged to electrically control connection and disconnection of an electrical power input of the electric power supply device. A power supply device is also disclosed.
Description
technical field [0001] The present invention relates to a power supply device and a connector for a device. More specifically, the present invention relates to user intuitive control of the input of power to a power supply device. Background technique [0002] Power supply equipment for devices is frequently used. It may be a charger for a mobile phone, personal digital assistant, laptop computer, etc., or a direct current (DC) power supply device for electronic products such as wireless local area network nodes, computer accessories, consumer electronics, and the like. Power supplies are usually set up to provide a DC output. The power supply unit may be connected to AC mains for down-conversion and voltage rectification, or to a DC output for down-conversion or up-conversion of the voltage to a desired level, eg in a vehicle. The problem with these power supplies is that when the power supply is plugged into the input supply and left there, energy is dissipated, althoug...
