Description

Terminal plugboard structure for reactor

Technical Field

The utility model relates to the technical field of auxiliary structures of reactors, in particular to a terminal plugboard structure for a reactor.

Background

At present, the terminal of the reactor is more in specification. In order to save cost, insulating paper is generally used as a terminal board, and the metal terminals are fixed in a wrapping and folding manner. The material of the insulating paper determines that the assembly is easy to tear, or the crease angle of the insulating paper is too small, so that the inserting plate is easy to move downwards when the insulating paper is matched with the coil. For example, the small-sized reactor terminal soldering tin structure provided by the Chinese patent grant publication No. CN202771926U is convenient, quick and low in cost, but is not as reliable as the reliability brought by integral injection molding although the solder tin structure is wrapped by insulating paper. To reduce the costs associated with manual folding assembly, those skilled in the art continue to devote their eyes to the integral injection molding direction. For example, chinese patent publication No. CN110767426a provides a reactor that employs integral injection molding to improve the strength of metal terminals. Although the side portions thereof are provided with U-shaped notches, the purpose thereof is not to fix the coil. The leading-out modes of coils of the reactors of different types are various, and some of the reactors are led out from the side parts, and others are led out from the bottom parts. Therefore, the above two patents cannot solve the problem of versatility of the board structure for different reactor coils.
