Abstract

The invention provides a pushing structure of a high-voltage direct-current relay. The pushing structure comprises a fixed support, a stop piece, a movable reed and an elastic piece. The fixed supportcomprises two fixed side arms, a carrying plate and a pushing rod. The two fixed side arms are arranged on the two sides of the carrying plate respectively, and the push rod is connected with the bottom of the carrying plate. One end of the stop piece is connected with the tail end of one fixed side arm, and the other end of the stop piece is connected with the tail end of the other fixed side arm. One end of the elastic piece abuts against the carrying plate, the other end of the elastic piece abuts against the movable reed; and the movable reed is connected with the stop piece in an abutting mode, and the stop piece is provided with an arc separating portion. According to the pushing structure of the high-voltage direct-current relay, the assembling mode from the bottom up is adopted, the elastic piece, the movable reed and the stop piece are sequentially stacked, and the stop piece is fixedly connected with the two fixed side arms, so that the assembling process is simple and rapid, and the assembling efficiency of the high-voltage direct-current relay is improved. In addition, the arc separating portion plays a role in isolating the electric arc, so that the reverse electric life of the high-voltage direct-current relay is prolonged.

Description

technical field [0001] The invention relates to the technical field of high voltage direct current relays, in particular to a driving structure of high voltage direct current relays. Background technique [0002] At present, Chinese patent CN105551897B discloses a high-voltage DC relay and its assembly method, including two static contacts and a moving assembly; the moving assembly includes a moving spring part, a main spring and a push rod assembly; it is characterized in that: The push rod assembly is composed of two independent parts, the push rod part and the U-shaped basket. After being installed on the top of the push rod part in turn, fix the two ends of the straight piece type fixed piece to the bottom of the side part of the U-shaped basket respectively, so that the main spring is elastically tensioned on the bottom surface of the moving spring part and the insulation of the push rod part. Between the plastics, push the moving reed of the moving spring part to the ...
