The invention relates to the technical field of current protection equipment, and discloses a current protection device for electronic equipment installed on a vehicle, which includes a fixed base and a storage groove arranged at the upper end of the fixed base, and an electrode is used on the inner wall of one side of the installation groove on the top of the protector shell The fixed contact is set on the other side of the inner wall, and the moving contact rod is movably connected to the moving contact rod through the fixed block. The rod is movably socketed in the inner cavity of the fixed cylinder and connected to the metal block. An electromagnet is arranged on the bottom plate of the fixed cylinder. The electromagnet, the automatic control switch, the single-chip microcomputer and the current sensor form a series circuit. After the device is connected to the circuit of the car, the current The large-time current sensor detects the signal and transmits it to the single-chip microcomputer to control the automatic control switch to disconnect, drive the electromagnet to release the metal block to reset the support spring, push the boom top to separate the starting contact rod from the fixed contact, and disconnect the circuit of the additional equipment prevent it from being burned.
Description
technical field [0001] The invention relates to the technical field of current protection equipment, in particular to a current protection device for electronic equipment installed on a vehicle. Background technique [0002] In recent years, people's living standards have been continuously improved, and vehicles are playing an increasingly important role in life. In order to better meet people's use needs, vehicles are equipped with electronic equipment after purchase. Some parts are designed to meet the need of circuit overcurrent protection, and the current protection device has to be used in the installation of the circuit. [0003] Existing current protection devices generally use blown fuses. However, when the circuit current is too large, the fuse will be blown due to high temperature, and the equipment will be protected from power failure to prevent the equipment from being burned by the excessive current in the circuit. Once the fuse After the fuse is blown, the use...
