The positive cartridge set on housing tip is included, the outer end of the positive cartridge is provided with insulator cap, further includes being arranged in housing cavity
Circuit board further includes the output interface and end cap for being set to housing rear end, and the positive cartridge is additionally provided with an inner cavity, described interior
Be provided with positive spring in chamber, the positive cartridge is connected by the anode of positive spring and circuit board, the cathode shrapnel it is interior
Side is equipped with negative spring, and cathode shrapnel is connected by the cathode of negative spring and circuit board, and the lateral surface of the housing rear end is set
There is ventilation slot.
Wherein, the ventilation slot is along the axially extending of the shell.
Wherein, the lateral cross section of the ventilation slot is arc-shaped, and the ventilation slot has 2.
Wherein, the contact surface of the inner cavity of the positive cartridge and positive spring is planar structure.
Wherein, the output interface can be an output interface or multiple output interfaces.
The utility model due to cathode shrapnel by the cathode of negative spring and circuit board connect, ensure that cathode shrapnel with
The sensitivity of automobile cigarette lighter cathode contact and reliability enable to vapour since the lateral surface of housing rear end is equipped with ventilation slot
Heat in vehicle cigar lighter comes out, and has good heat sinking function, to improve the reliability of the utility model and make
Use the service life.
Description of the drawings
