Abstract
The invention discloses a high-power automobile rectifier bridge soldering method and a lug thereof. When diodes need to be soldered according to the conventional rectifier circuit connection method to form a high-power automobile rectifier bridge, the bases of the diodes are first fixedly embedded in a polar plate of the rectifier bridge, the polar plate is fixed on an insulating support of the rectifier bridge, lugs which are used for being soldered on the leads of the diodes to jointly form the high-power automobile rectifier bridge are respectively fixed beside each diode on the insulating support, the front soldering end of each lug is produced into the shape of a flat arrowhead, the butt-soldering method is then adopted to respectively solder the leads of the diodes on the soldering ends of the lugs fixed on the support, and thereby the high-power automobile rectifier bridge is formed. The invention not only has the advantages of lower soldering temperature and high product quality, but also has the advantages of simple structure, low production cost, small solder joints, material saving, high finished product rate and the like.
Description
Technical field
The present invention relates to a kind of welding method and lug plate thereof of high-power automobile-used rectifier bridge, belong to the rectifier bridge manufacture technology field.
Background technology
At present, when making high-power automobile-used rectifier bridge, the welding ends of lug plate often adopts the mode of U-shaped card structure on its high-power automobile-used rectifier bridge, when welding, after earlier 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 bigger, therefore formed bigger solder joint after the welding, this has not only wasted raw material, but also has taken assembly space; 2, existing this lug plate structure must adopt the higher soldering appliance of temperature 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 about 3000V), 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 the rectifier bridge, then corresponding main commutation diode will be switched on, thereby diode is caused great damage, sometimes even can make diode fails.3, because the volume of welding ends is bigger, temperature is higher when welding, and this high temperature that produces because of welding will cause very big damage, the service life that can reduce diode chip for backlight unit greatly to the chip of diode.Owing to have the problems referred to above, so the welding manner of existing high-power automobile-used rectifier bridge still is not ideal enough.
Summary of the invention
The objective 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, that 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, when diode is welded to form high-power automobile-used rectifier bridge by traditional rectification circuit connected mode, base with diode is mounted on the pole plate of rectifier bridge earlier, pole plate is fixed on the insulating support of rectifier bridge, on insulating support, the next door of each diode is fixing by the lug plate of forming high-power automobile-used rectifier bridge after the wire bonds that is used for diode jointly, the welding ends of this lug plate front end is made into flat arrowhead form, and the mode that adopts butt-joint is then welded the lead-in wire of each diode respectively with the welding ends that is fixed on the lug plate on the support.
The welding lug plate of a kind of high-power automobile-used rectifier bridge of the present invention that makes up 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 adopted technique scheme, the present invention is made into the welding ends of flat arrowhead form with the welding ends of lug plate, has reduced the volume of welding ends greatly, can adopt the mode of butt-joint to weld like this.Because the principle of butt-joint is to adopt the low pressure Short-Circuit High Current at short notice, makes 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 when therefore not having welding.Because the welding ends volume is less, the volume of the pad that produces is significantly smaller than existing pad volume, the welding temperature that produces simultaneously also is significantly less than the welding temperature of existing pad, so the welding temperature that 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 has not only that welding temperature is lower, the advantage of good product quality, but also have simple in structure, cost of manufacture is low, solder joint is little, save material, the yield rate advantages of higher.
