Multipurpose welder rectifier bridge

Abstract

The invention discloses a multipurpose welder rectifying bridge which comprises two C-shaped radiating fins and rectifying tubes, wherein the two C-shaped radiating fins are an upper radiating fin and a lower radiating fin respectively. The radiating fins are superposed in an insulating manner, an insulating plate is arranged between the radiating fins, a plurality of through holes are arranged on the upper radiating fin and the lower radiating fin correspondingly, the rectifying tubes are fixed in the through holes, the rectifying tubes on the upper radiating fin are connected with the rectifying tubes on the lower radiating fin correspondingly, leading slices are connected at interconnected joints and convexly extend out of the edges of the radiating fins so as to face the centers of the C shapes, conductive connection holes are arranged at the ends of the portions of the leading slices convexly extending out of the edges of the radiating fins, and a conductive contact angle is arranged at one end of each of the upper radiating fin and the lower radiating fin. The two C-shaped radiating fins are assembled by superposing, so that the rectifying bridge is not easy to deform. The multipurpose welder rectifying bridge is simple in process and fine in reliability, cannot cause blockage of important air ducts of an electric welder, good ventilation performance of the electric welder is kept, and accordingly normal operation of the electric welder can be guaranteed.

Description

technical field [0001] The invention relates to a circuit structure of a rectifier bridge, in particular to a multi-purpose welder rectifier bridge with good heat dissipation performance. Background technique [0002] Existing generators still use excitation generators, which adopt a carbon brush structure, which has the disadvantages of short service life, high manufacturing cost, and high power consumption. The rectifier bridge group for generators is a motor accessory that rectifies alternating current to direct current. Its structure generally includes a rectifying element plate and a rectifying tube. refer to figure 1 as well as figure 2 , the rectifier bridge group of the existing generator is generally equipped with C-shaped rectifier element boards, two rectifier element boards are connected, each rectifier element board is provided with a rectifier tube, and the three-phase AC input wiring is respectively connected to the rectifier on the heat sink. The current...

Problems solved by technology

There are some shortcomings in practical application of this structure applied to the rectifier bridge group of the generator. The large and small C-shaped structure connected by the inner and outer rings has poor heat dissipation performance, and the assembly of this structure is more troublesome, which is not conducive to later maintenance, etc.
