Collecting ring used for alternating-current generator and manufacturing method thereof

Abstract

The invention discloses a collector ring applied to alternators and a manufacturing method thereof, which can retain and simplify the characteristic of the overall shaping of the collector rings and avoid the defect of short circuit between the positive and negative electrodes of collector rings, thereby optimizing the manufacture technique of collector rings. The collector ring comprises a positive electrode ring, a negative electrode ring, lead wires of the positive electrode ring and the negative electrode ring, and, an insulation caulking ring arranged between the positive electrode ring and the negative electrode ring and used for separating the positive electrode ring and the negative electrode ring. The manufacturing method of the collector ring is that: firstly, the positive electrode ring and the negative electrode ring of the collector ring are processed respectively; secondly, the positive electrode ring and the negative electrode ring are positioned at the upper end and the lower end of the insulation caulking ring respectively; thirdly, the positive electrode ring, the negative electrode ring and the insulation caulking ring are injected integrally.

Description

Slip ring applied to alternator and manufacturing method thereof technical field The invention relates to an alternator part for automobiles, in particular to a collector ring applied to the alternator. In addition, it also relates to a slip ring manufacturing method. Background technique In the current manufacturing process of the collector ring of the alternator, it is generally to simplify the manufacturing process of the collector ring. At present, the most practical way is to adopt an integral structure to integrate the positive and negative poles of the collector ring, and then after manufacturing and assembling Perform mechanical processing to separate the positive and negative electrodes. In addition, since the lead-out wires of the negative electrode need to pass through the inner side of the positive electrode ring, the process of injection molding the lead-out wires of the positive and negative electrodes requires high process requirements, and because the lea...

Problems solved by technology

In addition, since the lead-out wires of the negative electrode need to pass through the inner side of the positive electrode ring, the process of injection molding the lead-out wires of the positive and negative electrodes requires high process requirements, and because the lead-out wires are prone to displacement during the injection molding process, it is easy to use A short circuit occurs during the

However, due to the material defect of the copper ring, during the machining process, there are copper scraps attached to the collector ring, and the copper scraps are too small to be found and cleaned, so it is easy to cause a short circuit between the positive and negative poles of the collector ring. And then cause a safety hazard to the generator
