Capacitor fixing structure of automobile generator rectifier

Abstract

The invention discloses a capacitor fixing structure of an automobile generator rectifier, which comprises a first spiral tube wound outside a capacitor, and the surrounding inner diameter of the first spiral tube is consistent with the diameter of the outer ring surface of the capacitor; a second spiral pipe and a conical spiral pipe are sequentially arranged outside the first spiral pipe, and the first spiral pipe, the second spiral pipe and the conical spiral pipe correspond to one another in position and are equal in screw pitch; a plurality of buffer marbles are uniformly distributed between the first spiral pipe and the second spiral pipe; a spiral thin plate is connected between the second spiral pipe and the conical spiral pipe; one end of the second spiral pipe is connected with a connecting frame, and the end, away from the second spiral pipe, of the connecting frame is provided with a circular ring pipe. The circular ring tube is in contact with one end, provided with the pin, of the capacitor, the circular ring tube and the capacitor are coaxial, and the pin of the capacitor penetrates through the circular ring tube. The capacitor can be fixed and protected conveniently, and the heat dissipation effect of the capacitor can be improved conveniently.

Description

technical field [0001] The invention relates to the technical field of automobile motor rectifiers, in particular to a capacitor fixing structure of an automobile generator rectifier. Background technique [0002] The car generator is one of the core components of the car. Its function is to supply power to the electrical equipment on the car and also to charge the battery. The function of the capacitor is to filter and provide a good waveform to the generator. When fixing the capacitor, most of the existing methods use a capacitor slot suitable for the capacitor to fix it. When the capacitor is arranged in the fixed slot, since the capacitor slot covers most of the outside of the capacitor, it is inconvenient for the capacitor to be quickly installed. At the same time, when the capacitor receives an external shock, the buffer protection effect of the capacitor is poor, so it is easy to cause the capacitor pin to fall off the connecting piece. SUMMARY OF THE INVENTION ...

AI Technical Summary

Problems solved by technology

When fixing the capacitor, the existing methods mostly use a capacitor slot that matches the capacitor to fix it. When the capacitor is placed in the fixing slot, since the capacitor slot covers most of the outside of the capacitor, it is inconvenient to fasten the capacitor. Heat dissipation, at the same time, when the capacitor receives an external impact, the buffer protection effect on the capacitor is poor, so it is easy to cause the capacitor pin to fall off the connecting piece
