Description

A kind of welding method of high-power automobile-used rectifier bridge and lug plate thereof
Technical field
The welding method and the lug plate thereof that the present invention relates to a kind of high-power automobile-used rectifier bridge, belong to rectifier bridge manufacture technology field.
Background technology
At present, in the time making high-power automobile-used rectifier bridge, on its high-power automobile-used rectifier bridge, the welding ends of lug plate often adopts the mode of U-shaped card structure, in the time of welding, after first the lead-in wire of diode being mounted on the welding ends of U-shaped cassette of lug plate, weld again, adopt the lug plate of existing this structure to weld, mainly exist following problem: 1, because the volume of welding ends is larger, therefore after welding, formed larger solder joint, this has not only wasted raw material, but also has taken assembly space, 2, existing this lug plate structure must adopt the soldering appliance that temperature is higher to weld, often adopt argon arc welding to weld in prior art, and the principle of argon arc welding is argon arc welding machine generation high frequency oscillation voltage (about 3000V left and right), utilize thorium tungsten or cerium tungsten bar to do electrode, point discharge, puncture air, between solder joint, produce electric arc, utilize the contact resistance generation high temperature at pad place to carry out molten solder, because the physical location of argon arc soldering tip has certainty scarcely, if metal parts mistake arcing phenomenon on appearance and rectifier bridge, corresponding main commutation diode will be switched on, thereby diode is caused to great damage, sometimes even can make diode fails. 3, because the volume of welding ends is larger, in the time of welding, temperature is higher, and this high temperature producing because of welding will cause very large damage to the chip of diode, can greatly reduce the service life of diode chip for backlight unit. owing to there being the problems referred to above, so the welding manner of existing high-power automobile-used rectifier bridge or not ideal enough.
Summary of the invention
The object of the invention is to, provide that a kind of welding temperature is lower, product quality is higher and welding method and the lug plate thereof of high-power automobile-used rectifier bridge simple in structure, cost of manufacture is lower, to overcome the deficiencies in the prior art.
Technical scheme of the present invention is achieved in that the welding method of a kind of high-power automobile-used rectifier bridge of the present invention is, in the time that diode is welded to form to high-power automobile-used rectifier bridge by traditional rectification circuit connected mode, first the base of diode is mounted on the pole plate of rectifier bridge, pole plate is fixed on the insulating support of rectifier bridge, on insulating support, the side of each diode be fixed with one for the wire bonds of diode after the lug plate of the high-power automobile-used rectifier bridge of common composition, the welding ends of this lug plate front end is made into flat arrowhead form, then the mode that adopts butt-joint is welded the lead-in wire of each diode respectively with the welding ends that is fixed on the lug plate on support.
The welding lug plate of a kind of high-power automobile-used rectifier bridge of the present invention building according to said method is: comprise the lug plate on the insulating support that is fixed on high-power automobile-used rectifier bridge, be provided with the welding ends that is shaped as flat arrowhead form at the front end of lug plate.
Above-mentioned lug plate is the laminated structure of copper coin, and the welding ends of the lug plate of the laminated structure of its copper coin be shaped as flat arrowhead form.
Owing to having adopted technique scheme, the present invention is made into the welding ends of lug plate the welding ends of flat arrowhead form, has greatly reduced the volume of welding ends, can adopt like this mode of butt-joint to weld. Because the principle of butt-joint is to adopt at short notice the large electric current of low-voltage short-circuiting, make pad place metal molten, its welding temperature is lower than argon arc welding, and can not produce electric arc between solder joint, the short circuit problem while therefore there is not welding. Due to welding ends small volume, the volume of the pad that produces is significantly smaller than existing pad volume, the welding temperature producing is also significantly less than the welding temperature of existing pad simultaneously, and the welding temperature that therefore the present invention produces can not cause harmful effect to the chip of diode. So the present invention is compared with prior art, the present invention not only has advantages of that welding temperature is lower, good product quality, but also have simple in structure, cost of manufacture is low, solder joint is little, save material, yield rate advantages of higher.
