Background
The rectifier for the automobile engine has the main functions that alternating current generated by an automobile generator is rectified through the rectifier and converted into direct current to be used by all electrical appliances on an automobile, and meanwhile, an automobile storage battery is charged, so that enough electric energy is ensured when the automobile is started. The rectifier for the automobile generator in the prior art mainly comprises a plastic support, an anode heat dissipation plate, a cathode heat dissipation plate, an anode diode, a cathode diode, an insulation bushing, a hollow rivet, a B + screw rod, a nut and the like. The automobile generator rectifier utilizes the one-way conductive characteristic of the diode to realize the rectification function, the diode can generate a large amount of heat in the rectification process to cause the temperature of the diode to rise, and the heat is mainly distributed out in time through the anode cooling plate and the cathode cooling plate to help the diode to cool so as to ensure the normal work of the diode.

In the rectifier in the prior art, a stator wire connecting terminal is L-shaped, and when the stator wire is connected with the L-shaped terminal in the assembling process of the generator, the stator wire cannot be fastened by the L-shaped terminal, so that the stator wire cannot be fixed easily, and defects such as insufficient welding of the stator wire during welding, infirm fixing of the stator wire, vibration falling and the like easily occur, so that the function of the generator is lost, and the vehicle cannot be started or normally run.
Along with the development of the energy-saving and emission-reducing technology of the automobile industry, the energy efficiency conversion requirement of the generator is continuously improved, and the rectifier needs to meet the matching requirement of the double-star stator generator, so that the rectifier needs to meet two conditions: firstly, the rectifier is provided with a W1 terminal and a W2 terminal; and secondly, the position of a B + terminal mounting hole on the rectifier is matched with the position of a mounting hole of a regulator for the double star stator generator. The rectifier in the prior art has only one W1 terminal, and the position of a B + terminal mounting hole on the rectifier is not matched with the position of a mounting hole of a regulator for a double star stator generator, so the rectifier has poor universality.
