A rectifier bridge frame with square contact surface and preparation method thereof

Abstract

The invention discloses a rectifier bridge framework with a square contact surface. The rectifier bridge framework comprises a left framework and a right framework, wherein the left framework is connected with the right framework through a connection plate; the left framework and the right framework are symmetrically arranged about the connection plate used as a center, and the left framework andthe right framework are of the same specification; and a left elastic sheet is arranged on the left framework, and a right elastic sheet corresponding to the left elastic sheet is arranged on the right elastic framework. According to the rectifier bridge framework with the square contact surface, by the adding of a supporting plate on the framework, the contact surface of the supporting plate is square and is matched with a welding plane of a chip; in a welding process, chip deviation can be avoided, and a certain deviation correction effect can be achieved on the chip deviation in a crystallization process; more effective supports are provided for welding of the square supporting plate to the contact surface framework under the same cross sectional area, so that the effective area of welding is enlarged.

Description

technical field [0001] The invention belongs to the technical field of rectifier bridges, in particular to a rectifier bridge frame with a square contact surface, and also relates to a preparation method for a rectifier bridge frame with a square contact surface. Background technique [0002] The rectifier bridge is to seal the rectifier tube in a shell, which is divided into full bridge and half bridge. The full bridge is to seal the four diodes of the connected bridge rectifier circuit together, and the half bridge is to seal the half of the four diode bridge rectifiers together. Two half bridges can be used to form a bridge rectifier circuit. The bridge can also form a full-wave rectification circuit with a center tap of the transformer, and the rectification circuit and operating voltage should be considered when selecting a rectifier bridge. [0003] The rectifier bridge is usually connected by two or four rectifier silicon chips, two of which are called half bridges, ...
