Abstract
The present invention discloses an overload protection control mechanism for a power supply, wherein a control mechanism installed between two connectors automatically switches the DC power states of the output signal of the overload protection circuit according to the electric connection state between two connectors. Thereby, the present invention not only can prevent the user, who lacks the knowledge of the overload protection circuit, from incorrectly operating the overload protection circuit but also can protect electronic devices from the damage induced by that an unintended touch switches the overload protection circuit erroneously.
Claims22
An overload protection control mechanism for a power supply, comprising:
- an overload protection circuit, built inside a power supply and determining the DC power state of its output signal according to the value of the power output by said power supply;
- and
- a control mechanism, further comprising:
- a first connector, an adapter device and a control element, wherein said first connector is arranged in the output end of said power supply;
- said adapter device has a second connector, which can be electrically connected to said first connector, and transmits power to a back-end electronic device;
- said control element is installed in the place where said first connector is electrically connected to said second connector;
- said control element generates a first signal when said first connector and said second connector are in an electric connection state and generates a second signal when said first connector and said second connector are in an electric disconnection state;
- when said first signal is input into said overload protection circuit, said overload protection circuit enters a first overload protection mode;
- when said second signal is input into said overload protection circuit, said overload protection circuit enters a second overload protection mode.
