Embodiment 1
[0022] Embodiment one: see figure 1 , figure 2 , an automatic switching resistor connector comprising a socket 2, an elastic connector 3, a fixed terminal 4, a sliding rheostat 5, a card slot 6, an electromagnet 7, and a fixed spring 11. The electromagnet 7 will have an attractive force when the car is started. Suction the elastic connection 3 to the top, and connect the fixed terminal 4 above, so that the resistance in the circuit can be a larger resistance value, and when the flame is turned off, the electromagnet 7 is powered off, and if there is no force, the fixed spring 11 will turn the elastic The connecting body 3 is pressed downward and is connected to the sliding rheostat 5 with a smaller resistance.
Embodiment 2
[0023] Embodiment two: see figure 1 , image 3 , Figure 4 , an automatic switching resistor connector including plug 1, plug 2, electromagnet 7, power supply 8, temperature resistor 9, and cylinder 10. When the car starts, the temperature of cylinder 10 rises, and the resistance value of temperature resistor 9 is very small. The circuit forms a loop, and the electromagnet 7 will generate an attractive force to adjust the change of the resistance. The connection between the plug 1 and the socket 2 is circular, which is more stable and better connected.
