Further, the speed adjusting resistance is ceramic coiling speed adjusting resistance, and ceramic coiling speed adjusting resistance is provided at both ends with piece
Shape pin is provided with the mating slot of blade prongs on the resistance mounting plate.
Further, also it is connected on the bottom surface of the resistance mounting plate and socket, has first to connect in the socket
The first power supply lead wire connection of line piece, the second lug plate and the 3rd lug plate, first lug plate and fan electromotor, described the
One end lead of two lug plates and speed adjusting resistance connects, the other end lead of the speed adjusting resistance and the first power supply of fan electromotor
Lead connects, and the second source lead of the 3rd lug plate and fan electromotor connects.
The beneficial effects of the utility model：
1st, the automotive electronics fan of the anti-speed adjusting resistance high temperature damage of the utility model, by the way that speed adjusting resistance is installed on fan
The leading flank of frame, the leading flank of fan frame are windward side, the natural wind and electronic fan so driven in vehicle traveling process
The wind generated that works can pass through speed adjusting resistance, so as to effectively be radiated to speed adjusting resistance, avoid speed adjusting resistance in high temperature
Lower work, ensures its reliably working, can extend the speed adjusting resistance service life.
2nd, the automotive electronics fan of the anti-speed adjusting resistance high temperature damage of the utility model, since speed adjusting resistance is mounted on fan frame
Leading flank so that speed adjusting resistance will not occupy engine nacelle, can effectively reduce the installation occupied space of electronic fan,
Suitability, the commonality of electronic fan can be improved.
