Galvanic electricity becomes direct current.
Currently, the rectifier bridge occurred in market and data mainly by two pieces stacking and between there are clamping space installation
It plate, the diode being arranged on two mounting plates, the conductive haptic element at diode and is extended to outside two mounting plates by conducting wire
Lead assemblies composition, positioning bolt, positioning column, pipe, the conductive electrode that diode extends with conduction haptic element be welded to connect.Hair
The promising avalanche diode of diode selected when motor rectification, avalanche diode are the collisions using carrier in semiconductor structure
Ionization and two kinds of physical effects of transition time and generate the solid state microwave device of negative resistance, existing avalanche diode is generally rectangular
Or irregular shape reduces efficiency, cost is also opposite to be improved to increasing difficulty in production process.And with automobile electricity
Increasing, the application of instantaneous power equipment of sub-platform, cause the output power of rectifier bridge also must with increase, therefore,
It also increased on existing single avalanche diode capacity.Automobile is usually in use, because road conditions problem inevitably can
There are big vibrations, moved so as to cause the positioning bolt of mounting plate, so that mounting plate positioning is not firm, so that rectification
Bridge working performance is unstable.
Utility model content
The utility model aim is to provide a kind of automobile generator rectifier bridge, can make mounting plate still in the big vibrations of automobile
Firm position, and output power increases and can reduce in process of production cost, improves efficiency.
Technical solutions of the utility model are as follows：A kind of automobile generator rectifier bridge, include two pieces stacking and between there are
It is clamped the mounting plate in space, the diode being arranged on two mounting plates, copper sheet, conductive haptic element at diode and by leading
Line extends to the lead assemblies outside two mounting plates, the pipe being located on mounting plate, fixed hole, it is characterised in that：Described two
Pole pipe is avalanche diode, the avalanche diode use chip be arranged and shape be circle and be directly welded on copper sheet,
The round chip diameter is more than avalanche diode diameter, and the circular core on piece is set there are one cooling fin, round chip
With insulating heat conductive silicon grease layer is additionally provided among cooling fin, the round chip is mutually fixed by bond plies with cooling fin,
It is equipped with crash roll on the outside of the mounting plate, several radiating ribs, the heat dissipation are additionally provided on the outer ledge of two pieces of mounting plates
Muscle is located at setting above crash roll.
The utility model is further arranged to, and described two pieces of mounting plates are positive plate and negative plate.
The utility model is further arranged to, and the crash roll is plastic cement material.
The utility model has the advantages that：Avalanche diode in automobile generator rectifier bridge is rectangular from before
Or irregular shape is changed to that production cost can be reduced after circle, improves production efficiency, the diameter of avalanche diode becomes larger, can
The output for increasing electric current is suitable for the occasion more than automotive electronics platform to make the output power of rectifier bridge increase, crash roll
The stability of rectifier bridge can be increased by being arranged, and make to occur shaking greatly when running car to cause mounting plate also can be very firm, will not
Influence the work of rectifier bridge.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Figure label meaning is as follows：1- mounting plates；2- copper sheets；3- circle chips；4- cooling fins；5- crash rolls；6- is led
Electric haptic element；7- pipes；8- fixed holes；11- radiating ribs.
Specific implementation mode
As shown in Figure 1, include two pieces stacking and between there are clamping space mounting plate 1, be arranged on two mounting plates
Diode, copper sheet 2 conductive haptic element 6 at diode and extends to the lead assemblies outside two mounting plates, position by conducting wire
In the pipe 7 on mounting plate, fixed hole 8, it is characterised in that：The diode is avalanche diode, the snowslide two
Pole pipe uses that chip 3 is arranged and shape is round and is directly welded on copper sheet that 3 diameter of round chip is more than existing
Avalanche diode diameter is set on the round chip 3 there are one cooling fin 4, and the round chip 3 passes through bond plies
It is fixed with 4 phase of cooling fin, 1 outside of mounting plate is equipped with crash roll 5, and existing rectifier bridge is typically all by avalanche diode
As direct chip attachment on copper sheet, avalanche diode, which makes round chip 3, can facilitate production, reduce cost, improve effect
The diameter increase of rate, avalanche diode can increase output, and rectifier bridge output power also improves, the instantaneous power equipment in automobile
It can preferably use, the installation of cooling fin 4 can carry out dissipation to being welded on the heat that avalanche diode generates on copper sheet, because
Become larger for the diameter of avalanche diode, heat fatigue may be will produce, influence service life, the installation of cooling fin 4 can slow down this
Phenomenon, crash roll 5 can make rectifier bridge fix the normal use for avoiding influencing parts when car big vibrations, described
Two pieces of mounting plates 1 are positive plate and negative plate, and insulating heat conductive silicon grease layer, institute are additionally provided among the circle chip 3 and cooling fin 4
The crash roll 5 stated is plastic cement material, and several radiating ribs 11, radiating ribs 11 are additionally provided on the lateral wall of described two pieces of mounting plates 1
On crash roll 5, the heat that can be generated to rectifier bridge sheds, and improves the service life of rectifier bridge.
