Axial array type rectifier bridge stack

Abstract

The invention relates to the technical field of electrical elements, and discloses an axial array type rectifier bridge stack; the axial array type rectifier bridge stack comprises a lower mounting shell, wherein an upper mounting shell is clamped on the top of the lower mounting shell; the top of the upper mounting shell is movably sleeved with four symmetric screws, and the bottoms of the screwsare in threaded connection with the top of the lower mounting shell; and a first frame, a second frame, a third frame and a fourth frame are clamped on the top of the lower mounting shell. Accordingto the axial array type rectifier bridge stack, by virtue of matching of the first frame and the second frame, and matching of the third frame and the fourth frame, the first frame and the third frameare connected with the second frame and the fourth frame respectively, and a first chip, a second chip, a third chip and a fourth chip are consistent in polarity arrangement, so that when a first jumper wire is connected with the first chip, the polarity of the first chip cannot be considered, so that the phenomenon of circuit damage is prevented.

Description

technical field [0001] The invention relates to the technical field of electrical components, in particular to an axial array rectifier bridge stack. Background technique [0002] The rectifier bridge stack is a rectifier device composed of two or four diodes. The bridge stack has half bridge, full bridge and three-phase bridge. The three kinds of half bridges have two types: positive half bridge and negative half bridge. Generally, there are four chips to be welded. The polarities of the two sides of these chips are different. Once the chips are installed upside down, it is easy to cause the components to burn early, and the existing device is often prone to tilt when soldering jumpers, resulting in inaccurate soldering positions. , which reduces the service life and performance of the components. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides an axial array rectifier bridge stack, which solves the problems ...
