Description
Technical field
The utility model is related to a kind of rectifier of automobile current generator, belongs to auto parts machinery, especially a kind of automobile hair
The B+ output screw protective case fixed structures of motor rectifier.
Background technology
Rectifier is one of critical piece of AC generator for vehicle, and it has two major functions：First, by alternating current
（AC）Become direct current (DC), filtered rear supply load, or supply inverter；Second, provide charging voltage to battery.
The primary structure of rectifier is by B+ output screws protective case, B+ output screws, positive plate, bridge bracket, screw rod, excitatory
The parts such as diode, positive diode, backing plate, negative plate (end cap), negative diode are constituted.The B+ output screws protection of rectifier
Covering major function is：B+ screw rods are connected with larger electric current, it is necessary to by B+ output screws protective case and external insulation when working.Its
Middle B+ output screws protective case and positive plate B+ output ends use the frame mode that gap coordinates, and the rectifier of the structure exists following
Defect：1st, due to being gap fit structure, so rectifier bridge is in transportation, easily come off damage.
2nd, the structure needs one locking nut of increase on B+ screw rods after assembling motor, and progress prevents screw rod from protecting
Set comes off, and in entrucking, the locking nut will also be taken off, and increases assembly process cost.
3rd, shaken after entrucking during use very greatly, because gap coordinates, screw rod protective sleeve can occur ceaselessly to quiver
It is dynamic, easily fasten Wiring Harness of Battery on abrasion output bolt, cause loose contact, produced between B+ screw rods compared with
Big contact resistance, generates heat rapidly under high current effect, can cause to burn car when serious.
The content of the invention
The purpose that the utility model is related to is to overcome the shortcomings of prior art there is provided a kind of B+ of automobile current generator rectifier
Output screw protective case fixed structure, the structure increase sets buckle boss and anti-rotation convex tendon, solves rectifier transport and uses
During cause B+ output screws protective case rotate or come off so that cause failure the problem of.Quality for raising rectifier can
By property, there is provided sound assurance for the safety traffic of vehicle.
The technical solution of the utility model is：A kind of B+ output screw protective case fixed knots of automobile current generator rectifier
Structure, including B+ output screws protective case, B+ output screws, positive plate, bridge bracket, screw rod, excitation diode, positive diode, backing plate,
Negative plate, negative diode, it is characterised in that：B+ output screws protective case is added with positive plate B+ output ends using interference to be clasped
Structure；Coordinate in B+ output screws protective case and positive plate B+ output ends and have additional 2 ~ 4 interference convex tendons and two anti-rotations on internal diameter
Groove, coordinates in B+ output screws protective case and positive plate and buckle is provided with plane.
In positive plate B+ output ends provided with the buckle boss coordinated, and two are provided with B+ output cylinder external diameters are coordinated
Anti-rotation convex tendon.
The beneficial effects of the utility model are：
1. positive plate uses compression molding process, it is ensured that the boss that is clasped is consistent with the fit dimension of anti-rotation convex tendon
Property；
2. B+ output screws protective case uses injection molding process, and interference convex tendon and buckle structure effectively prevent protective case from turning
Loosen, the risk come off.
3. B+ output screws protective case uses injection molding process, and anti-rotation groove effectively prevents protective case from rotating.

D, buckle boss；E, anti-rotation convex tendon；F, B+ export cylinder.
Embodiment
As depicted in figs. 1 and 2, the utility model includes B+ output screws protective case 1, B+ output screws 2, positive plate 3, bridge branch
Frame 4, screw rod 5, excitation diode 6, positive diode 7, backing plate 8, negative plate (end cap) 9, negative diode 10.B+ output screws are protected
Set 1, B+ output screws 2, positive diode 7 are assemblied on positive plate 3；Negative diode 10 is assemblied on negative plate (end cap) 9；It is excitatory
Diode 6 is assemblied on bridge bracket 4, is finally fixed bridge bracket 4, positive plate 3, backing plate 8, negative plate (end cap) 9 using screw rod 5
Together.
As shown in Fig. 3, Fig. 4 and Fig. 5, the B+ output circles on B+ output screws protective case 1 on interference convex tendon b and positive plate 3
Post f interference extrusions are assembled, on positive plate 3 in the anti-rotation groove c of anti-rotation convex tendon e insertion B+ output screws protective case 1, B+ output spiral shells
Buckle a is fastened on the buckle boss d of positive plate 3 on bar protective case 1, it is ensured that B+ output screws protective case 1 uses process in transport
Middle anti-rotation anticreep.
