Abstract
A kind of three-edged type alternator rectifying bridge for vehicle, just comprise, negative pole fin, both positive and negative polarity diode and circuit board, just, negative pole fin and circuit board both sides are provided with through hole, just, between negative pole fin, insulation connection seat is set, insulation connection seat is inserted in described through hole, will just, press-fited by stay bolt after the assembling of negative pole fin and tighten together, its special character is: be vertical plane in corresponding positive pole welding diode position, the through hole of positive pole radiating fin both sides, the distance at described vertical plane and adjacent positive pole diode mounting groove edge is 0.9mm-1.1mm, on negative pole fin, between corresponding two adjacent diodes, centre position is provided with a single wing fin and single wing fin horizontal center line and adjacent diode horizontal centre linear distance are 7.4mm-7.6mm.Owing to not having expanding surface around radiating groove, scaling powder can not flow out fin along expanding surface, thus avoids solder flux to trickle to fin surface affecting product appearance, improve product surface quality, meet consumers' demand.
Description
Technical field
Basis is practical relates to a kind of three-edged type alternator rectifying bridge for vehicle.
Background technology
Existing three-edged type alternator rectifying bridge for vehicle comprises positive and negative electrode fin, multiple diode is installed in the radiating groove of positive and negative electrode fin, circuit board is connected with by diode pin, through hole is provided with in positive and negative electrode fin both sides, between positive and negative electrode fin, insulation connection seat is set, described insulation connection seat is inserted in the through hole of positive and negative electrode fin both sides, is fixed together between circuit board, both positive and negative polarity fin, insulation connection seat by stay bolt.Be provided with sloping platform in corresponding welding diode position, the through hole of positive pole radiating fin both sides, between the diode that correspondence two is adjacent on negative pole fin, position is respectively equipped with twin fin, and the corresponding diode location of each twin fin is sloping platform.First put scaling powder during welding diode and put solder plate, then putting diode, then entering high temperature furnace and weld.Problems existing is: after putting complete diode, and scaling powder is full of heat radiation film trap, and owing to there is expanding surface around radiating groove, scaling powder can flow out fin along expanding surface, thus causes bad order, affects product surface quality.
Summary of the invention
The utility model will solve the problems referred to above that prior art exists, and provides a kind of three-edged type alternator rectifying bridge for vehicle, to prevent scaling powder from trickling to fin surface along expanding surface, and then meets the requirement of product surface quality.
Technical solution of the present utility model is: a kind of three-edged type alternator rectifying bridge for vehicle, just comprise, negative pole fin, just, be welded with just multiple in the mounting groove of negative pole fin, negative pole diode, just, negative pole diode pin place is connected with circuit board, just, negative pole fin and circuit board both sides are provided with through hole, just, between negative pole fin, insulation connection seat is set, described insulation connection seat is just inserted into, in the through hole of negative pole fin both sides, will just, after the assembling of negative pole fin, by passing circuit board, the stay bolt of insulation connection seat by circuit board and just, negative pole fin press-fits and tightens together, its special character is: be vertical plane in corresponding positive pole welding diode position, the through hole of positive pole radiating fin both sides, distance between described vertical plane and adjacent positive pole diode mounting groove outer ledge is 0.9mm-1.1mm, on negative pole fin, between corresponding two adjacent diodes, centre position is provided with a single wing fin and distance between each single wing fin horizontal center line and adjacent diode horizontal center line is 7.4mm-7.6mm.
The beneficial effects of the utility model are: by improving heat radiating fin structure, do not have expanding surface around radiating groove, scaling powder can not flow out fin along expanding surface, thus avoids solder flux to trickle to fin surface affecting product appearance, improve product surface quality, meet consumers' demand.
