Description
Technical field
The application is relevant with electric equipment generally, and is particularly relevant with electronic package and manufacture method thereof with diode rectifier bridge, adjuster and brush handle assembly of being used for motor.
Background technology
The electric loading of the vehicles is in sustainable growth.Simultaneously, generator can with whole package size continue to reduce.Therefore need the system of higher power density and the method for generation veneer electric current.
Growth of requirement to current generated by AC generator needing to cause the corresponding adaptive of electric current Adjustment System, especially the three-phase alternating current that produces of alternating current generator is used the system that rectification becomes direct current, and direct current can be stored among the battery of the vehicles or be directly used in the vehicles circuit of DC-voltage supply.
The rectification of three-phase alternating current generally realizes by the rectifier bridge with six power diodes.Three in these diodes is positive diode, and is connected between the positive terminal B+ of the phase terminal of alternator frame winding and generator, and positive terminal is connected to the battery and the circuit of the vehicles.Other three diodes are called negative diode, are connected the electrical grounding of the vehicles or greatly and between the phase terminal of stator former winding.
Diode has been formed rectifier bridge and has been born big electric current.Therefore, be necessary with effective method cooling diode as far as possible.In order to reach this purpose, well-known is that diode is placed on the metallic plate, and metallic plate is placed on the outside of alternating current generator and has formed the radiator of the heat that is used for the diode generation.The diode grouping is placed on two support plates, and one of them is specialized in positive diode and uses, and another is specialized in negative diode and uses.
Rectifier diodes is connected to support plate separately, and these support plates also are used as the radiator of these diodes.Rectifier diodes inserts the reception boring of support plate or radiator by pressure, or uses suitable welding alloy to be welded to support plate.The terminal lead that is connected to rectifier diodes makes rectifier diode can be connected to external power source.

The current capacity and the heat dissipation characteristics that improve bridge rectifier have been included in installation semiconductor diode chip on first and second metal heat sinks, and radiator is by a thin slice electrical insulating material electrically insulated from one another.Protected again insulating coating covered after diode chip for backlight unit was connected to separately radiator.One of metal heat sink comprises heat sink area, and it suffers cooling air when bridge rectifier is installed to generator.The radiator that has a plurality of fin comprises 12 air flues.Shown in Di Er people's such as (Steele) the United States Patent (USP) 4,606,000, it is combined in this to the bridge rectifier of this type by reference like that.
As time passes and vibration effect, the electrical integrity of electronic circuit can since the fatigue of mechanical stress generation lost efficacy.This will produce the electricity output loss of motor.And some elements are required to provide output to connect, so the cost of the cost of part or element and assembling is very high.
People need improve the performance characteristics of the bridge rectifier of prior art.In addition, also need support plate to increase heat radiation and more effective cooling diode to diode, this is by promoting to enlarge the surface area of the radiator that diode can use, thereby the rate of heat dissipation of the support plate of diode through laying diode is improved.And, also needing package assembling that can stand to vibrate, more solid, it can provide effective and cost-effective heat radiation.
