Description
Technical field
the utility model relates to a kind of high-power automobile-used rectifier bridge, belongs to the rectifier bridge manufacture technology field.
Background technology
are present; When making high-power automobile-used rectifier bridge; Generally adopt the diode of bolt type to make, the high-power automobile-used rectifier bridge of this employing bolt type diode must be screwed into the diode of bolt type on the mounting panel when making; According to the connected mode of bridge rectifier, after welding respectively, the mode of employing welding diode anodal to each and negative pole makes it to form a complete rectifier bridge then.The high-power automobile-used rectifier bridge that adopts existing this mode to make; Not only exist complex manufacturing technology, difficult installation, cost is higher, mechanical strength is relatively poor problem; And because traditional bolt type diode all is the secondary welding structure; Its thermal resistance is very big, the problem that heat radiation is relatively poor when therefore also existing work, useful life is short.So the result of use of existing high-power automobile-used rectifier bridge still is not ideal enough.
Summary of the invention
The purpose of
the utility model is, the high-power automobile-used rectifier bridge that a kind of thermal resistance is lower, heat radiation is better and simple in structure, fabrication and installation easy, cost is lower, useful life is long is provided, to overcome the deficiency of prior art.
The technical scheme of
the utility model is to constitute like this: a kind of high-power automobile-used rectifier bridge of the utility model is: this rectifier bridge comprises insulating support and connects to form the diode of bridge rectifier by the bridge rectifier mode; The base of its diode is mounted in respectively on two pole plates; Two pole plates are fixed on the insulating support; Each diode side all is fixed with a lug plate on insulating support; Each lug plate all respectively with the wire bonds of a diode together; Diode is through constituting a complete bridge rectifier with interconnecting of pole plate and lug plate, and the output cathode that pole plate is this bridge rectifier, and the output negative pole that another piece pole plate is this bridge rectifier.
all are equipped with 6 diodes on above-mentioned every pole plate.
The rated current of
above-mentioned diode is 35A～40 A, the puncture voltage>=300V of diode.
are equipped with electric capacity on above-mentioned insulating support; And the positive pole of electric capacity is connected with pole plate as output cathode; The negative pole of electric capacity is connected with pole plate as output negative pole, extremely goes up through bolt and is connected with the electric capacity lead-in wire respectively positive and negative two of electric capacity.
are owing to adopted technique scheme; The utility model has been abandoned the bolt type diode structure that is adopted on traditional high-power automobile-used rectifier bridge fully, and the utility model adopts the pole plate of the metallic plate of two conductions as the power rectifier bridge, and all directly is mounted on the pole plate respectively all diodes of forming bridge rectifier; Making and mounting process have so not only been simplified greatly; Reduced production cost, and because the diode that the utility model adopted all is the diode of a welded type, and only need when mounted the lead-in wire of diode is welded on the lug plate through the mode of welding; Therefore the thermal resistance of the rectifier bridge structure of the utility model is very little; Its heat all dispels the heat through the bigger pole plate of area of dissipation in use, so the utlity model has good performance of heat dissipation, the pole plate that is adopted simultaneously is the metal structure of conduction; And diode all is to be mounted on the pole plate of metal structure, therefore the utlity model has higher intensity.So the utility model compared with prior art, the utility model not only has lower, the advantage preferably of dispelling the heat of thermal resistance, but also has advantages such as simple in structure, that fabrication and installation easy, cost is lower, useful life is long.
