Technical Field
[0001] The invention relates to an integrated structure of a brush holder ring and a connector of a rear wiper motor, which is mainly used in rear wiper motors of various types of automobiles. Background Art
[0002] As for the structure realizing the electrical function of the rear wiper motor, most of the structures on the market now adopt the split docking structure of the connector and the brush holder ring. This type of structure requires manual docking of the connector and the brush holder ring, which has the risk of poor contact between the two after docking and the problem of high manual docking assembly cost. Figure 4 The figure shows a schematic diagram of a conventional rear scraper motor brush holder ring component, 1 represents the brush holder ring component, 2 represents the connector, and the brush holder ring component and the connector need to be manually connected together.
