Abstract: A carbon brush holder with improved air vents includes a body, a housing, and an exhaust lid, which are provided with corresponding fixing structures for their convenient assembly or disassembly. The exhaust lid is formed with a diverging air channel. By the exquisite configurations of the fixing structures provided on its components, the carbon brush holder is easy to assemble and disassemble so as to facilitate replacement or repair of parts settled in the carbon brush holder. Besides, since the exhaust lid in the present invention has the diverging air channel opened at two sides thereof as the air vents, it significantly improves the efficiency in dust expelling and heat dissipating, thereby effectively preventing the air vent from blocked and preventing overheat caused by poor exhaust.

Abstract: A welding assembled structure of a diode in a rectifier is disclosed. Therein, a solid joint lead which is a lengthwise member with one end contacting a leader frame of the rectifier, and an opposite extended end bent and extended outward the leader frame, while having a soldering tag located at one side of the extended end. The diode has a pin with an extended end located in a restricting area defined by the solid joint lead and the soldering tag. The soldering tag is welded by a spot welding process and bent toward the solid joint lead under stress when melted at a high temperature and, so as to deform and clamp the pin of the diode together with the solid joint lead, thereby fix-clamping the pin of the diode. The diode is secured by spot welding from loosening during operation, thereby ensuring the performance of the rectifier.
