Novel dual-purpose bridge rectifier

Abstract

A novel dual-purpose bridge rectifier includes a frame and a jumper, the frame comprises a first frame, a second frame and a third frame, the first frame comprises a transverse first connecting piece,the right end of the first connecting piece vertically extends downwards to form a first pin, the second frame and the third frame are the same in structure and are arranged below the first frame ina bilateral symmetry mode, the second frame comprises a square second connecting piece, and a third chip is welded to the second connecting piece. The novel dual-purpose bridge rectifier has the advantages that two appearances are packaged through one frame at the same time, the frame is compatible with different client application scenes, two packaging modes can be compatible, a radiator can be added, automatic surface mounting is achieved, production raw materials and labor cost are saved, the operation efficiency is improved, the production yield is increased, and equipment investment costis reduced.

Description

technical field [0001] The invention relates to a novel dual-purpose rectifier bridge stack. Background technique [0002] Existing rectifier bridge stacks are generally divided into two packaging structures with screw holes in the middle and without screw holes in the middle, and these two structures are not compatible, that is, two frames must be produced for the two packaging structures, which requires production allocation. caused a certain impact. Moreover, in the existing structure, the size of the connecting piece is relatively limited, so the size of the chip is also limited, and the maximum power of the rectifier generally reaches 4 amperes. After the chip is soldered, the corners of the chip are closer to the screw holes, such as figure 1 As shown, in the process of soldering the chip, the corners of the chip are easily shifted into the screw holes. When a bolt is penetrated into the screw hole and fixed, the chip will be squeezed, causing the risk of chip failur...

[0002] Existing rectifier bridge stacks are generally divided into two packaging structures with screw holes in the middle and without screw holes in the middle, and these two structures are not compatible, that is, two frames must be produced for the two packaging structures, which requires production allocation. caused a certain impact

Moreover, in the existing structure, the size of the connecting piece is greatly limited, so the size of the chip is also limited, and the maximum power of the rectifier generally reaches 4 amperes.

After the chip is soldered, the corners of the chip are closer to the screw holes, such as figure 1 As shown, in the process of soldering the chip, the corners of the chip are easily shifted into the screw holes. When a bolt is penetrated into the screw hole and fixed, the chip will be crushed, causing the risk of chip failure.
