Description

Technical Field

[0001] The invention relates to a novel dual-purpose rectifier bridge stack. Background Art

[0002] The existing rectifier bridge stack is generally divided into two packaging structures: one with a screw hole in the middle and one without a screw hole in the middle. These two structures are incompatible, that is, two frames must be produced for the two packaging structures, which has a certain impact on production deployment. In addition, in the existing structure, the size of the connecting piece is greatly limited, so the size of the chip is also limited. The maximum power of the rectifier generally reaches 4 amperes. After the chip is welded, the corners of the chip are relatively close to the screw holes, such as Figure 1 As shown, during the chip welding process, the corners of the chip can easily deviate into the screw holes. When bolts are inserted into the screw holes to fix them, the chip will be squeezed and damaged, causing the risk of chip failure. Summary of the invention

[0003] In order to solve the above technical deficiencies, the present invention provides a novel dual-purpose rectifier bridge stack that is compatible with two packaging forms, improves operating efficiency, increases production yield, and reduces equipment investment costs.

[0004] The present invention is achieved by the following measures:

A jumper connecting piece, a second pin extending vertically downward from the lower end of the second connecting piece, the third frame includes a square third connecting piece, a fourth chip is welded on the third connecting piece, a second jumper connecting piece extends upward from the third connecting piece, a third pin extends vertically downward from the lower end of the third connecting piece, the upper right angle of the second connecting piece and the upper left angle of the third connecting piece are both cut off to form a hypotenuse, a first jumper is welded between the first chip and the first jumper connecting piece, a second jumper is welded between the second chip and the second jumper connecting piece, a third jumper is welded together with the fourth chip and the third chip, and a fourth pin extending vertically downward is welded at the left end of the third jumper. A through hole is provided in the middle of the first connecting piece of the first frame. A 45° hypotenuse is provided at the upper right corner of the first connecting piece of the first frame. The length of the first connecting piece is 10-11mm and the width is 2.5-3mm, and the length of the second connecting piece and the third connecting piece are 3-3.5mm and the width is 2.5-3mm. The first frame, the first jumper, the second jumper, the third jumper, the second frame and the third frame form a screw hole in the middle.
