An automatic power-off device for notebook power cords

Abstract

The invention discloses an automatic power-off apparatus for a notebook computer power wire. The automatic power-off apparatus comprises a main body box, wherein the inner bottom wall of the main bodybox is fixedly connected with a fixed block, the top of the fixed block is provided with a sliding groove, the left inner side and the right inner side of the sliding groove are respectively movablyconnected with a sliding block, the tops of the two sliding blocks are respectively fixedly connected with a sliding rod, the top ends of the two sliding rods are respectively fixedly connected with afixed ring, the inner surface of the fixed ring on the left side is fixedly connected with a first power supply wire, the inner surface of the fixed ring on the right side is fixedly connected with asecond power supply wire, the right end of the first power supply wire and the left end of the second power supply wire are respectively fixedly provided with a contact sheet, the separated sides ofthe two sliding blocks are respectively fixedly connected with a movable rod, one sides, facing each other, of the two sliding blocks are respectively fixedly connected with a moving rod. The automatic power-off apparatus for the notebook computer power supply wire, a notebook computer can be automatically protected in a power-off manner, so that the damage of the notebook computer components andthe unnecessary economical loss can be avoided.

Description

technical field [0001] The invention relates to the technical field of notebooks, in particular to an automatic power-off device for notebook power cords. Background technique [0002] The power cord is a wire that transmits current. Usually, the mode of current transmission is point-to-point transmission. The power cord can be divided into AC power cord and DC power cord according to the purpose. Usually, the AC power cord is a wire through a higher voltage alternating current. Due to the high voltage, wires can be formally produced only after obtaining safety certification under unified standards, while DC wires basically pass direct current with low voltage, so the safety requirements are not as strict as AC wires, but for safety reasons, countries still require unified safety certification. [0003] In a notebook, it is necessary to use the power line to transmit current to provide energy for the notebook. However, when the temperature of the notebook itself is too high,...
