Description
Technical field
The utility model relates to a kind of power rectifier bridge for automobile current generator.
Background technology
The effect of automobile rectifier bridge is, by the characteristic of the one-way conduction of diode, level is converted to unidirectional direct current at the alternating current that zero point fluctuates.The deficiency that typical high power rectifier bridge exists has: 1. structure is not compact, is inconvenient to assemble, and efficiency of assembling is low; Originally 12 diodes adopt 6 braces first to weld with scolding tin, connect with 6 high temperature silicon wires again, end gets up (each joint welds 2 lines) with 3 weld in addition, easy welding mistake, and wire sheath is silicon rubber, intensity difference, how crowded line is easily with pole plate vibration friction, crust damaged and causes short circuit; 2. original diode frenulum boss diode, this structure diodes is due to technological problems, and heatproof is low, and interference fit when press-fiting with heating panel produces stress easily makes diode chip for backlight unit lose efficacy, and the poor reliability life-span is short; 3. original wire generally uses scolding tin soldering with between diode, and heatproof is low, easy rosin joint, unstable product quality.
Summary of the invention
In view of the deficiency of background technology, the technical problems to be solved in the utility model is to provide a kind of compact conformation, is easy to assembling, the power rectifier bridge of effective improve production efficiency and product quality.
The technical solution adopted in the utility model is:
A kind of power rectifier bridge, comprise and being symmetrical set and the positive plate be fixedly connected with and negative plate, positive plate installs six positive diodes, four, outer ring inner ring two, six negative diodes installed by negative plate, also be four, outer ring inner ring two, it is characterized in that: pin and the metallic plate inserts A of inner ring four diodes are welded to connect, pin and the metallic plate inserts B of four diodes that outer ring is close to each other are welded to connect, outer ring mutually away from the pin of four diodes and metallic plate inserts C be welded to connect, metallic plate inserts A, metallic plate inserts B and metallic plate inserts C point of upper, middle and lower three layers are injection-moulded in same working of plastics, described working of plastics fixedly mounts at the upper surface of positive/negative plate.
The power rectifier bridge of said structure, adopts three strip metal plate inserts to be connected with 12 welding diodes, and three strip metal plate inserts integral molded plastics are inside same working of plastics simultaneously, compact conformation, can not make to produce mistake between line, be easy to assembling, effective improve production efficiency and product quality.
As preferably, described working of plastics is secondary injection molding, first time with metallic plate inserts B for the first injection-moulded plastic protective layer of inserts, second time with plastic protective layer, metallic plate inserts A and metallic plate inserts C for insert injection molding.Because the metallic plate insert design inside working of plastics is three-decker; distortion is easily produced in the processes such as plating, transport; particularly when injection moulding; can make under the effect of plastic injection power one, two layer or two, easily short circuit between three-ply metal inserts; technique scheme is adopted just to solve this problem; first first for metallic intermediate layer plate inserts injection-moulded plastic protective layer; and then injection moulding; no matter how metallic plate inserts is out of shape with plastic injection pressure much, all can not produce short circuit each other.
As preferably, described diode adopts press mounting type diode.Solve original band boss diode exist heatproof low, easily make the defect that diode chip for backlight unit lost efficacy, the poor reliability life-span is short when press-fiting.
As preferably, described metallic plate inserts adopts copper plate material.
As preferably, described working of plastics adopts the PPS material of fiberfill fibers glass.Ensure the heatproof requirement of rectifier bridge entirety.
As preferably, described metallic plate inserts adopts spot welding to be connected with between diode pin.Product is connected reliable.Also ensure the requirement of product heatproof simultaneously.
