（AC）Become direct current (DC), filtered rear supply load, or supply inverter；Second, provide charging voltage to battery.
The primary structure of rectifier bushing, B+ output screws, rivet, positive diode, positive plate, bridge bracket, is born by screw rod
The parts such as pole plate (end cap), negative diode, nut form.W end nuts wherein on bridge bracket are connected using spot-welding technology
Connect.
Following defect be present in the rectifier of the structure：
1. due to be using nut and connection sheet direct spot welding structure, so in pinpoint welding procedure the screwed hole of nut with
Connection sheet mounting hole is also easy to produce hole center of circle inconsistent phenomenon, and can not be done over again after there is dislocation.
2. due to clamping spot welding up and down using nut and the W ends connection sheet direct spot welding structure on bridge bracket, spot welding head,
The height dimension at point postwelding W ends it is difficult to ensure that, virtual connection phenomenon occurs during follow-up installation.
3. due to using nut and connection sheet direct spot welding structure, causing connection sheet and nut in pinpoint welding procedure high temperature
Overlay coating is damaged, and corrosion, which occur, in W ends during subsequently installation use causes motor failure.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of prior art, there is provided a kind of auto rectifier W ends locking nut fixed knot
Structure
.Rectifier W end points weldering nut structure is changed to buckle-type protection cap+nut structure, so as to improve the reliable of product quality
Property.

Structure includes screw arbor assembly, bushing, B+ output screws, rivet, positive diode, positive plate, bridge bracket, negative plate, negative diode, spiral shell
Female and buckle-type protection cap, it is characterised in that：Rectifier W ends are buckle-type protection cap, using injection molding process, in buckle-type
Interior six side's anti-rotation grooves are provided with the endoporus of protection cap, nut is provided with outer six sides of nut, and outer six sides of nut are put into buckle-type guarantor
In the interior six sides anti-rotation groove of protecting cover, protection cap back-off is provided with buckle-type protection cap and support assorted;Bridge bracket is using note
Moulding process is moulded, the bridge bracket boss for coordinating back-off is provided with bridge bracket W ends, the protection cap back-off of buckle-type protection cap is buckled in bridge
Nut is pushed down using the W ends connection sheet of bridge bracket simultaneously on the bridge bracket boss of support, is pushed down on positive plate provided with anticreep convex tendon
Buckle-type protection cap.The nut at described W ends and the W ends connection plate rack of bridge bracket are loose fit, and locking screw is used at W ends
During bar, the center of circle of nut can align according to connection sheet central hole location adjust automatically.
Described buckle-type protection cap is used with bridge bracket and snapped connection.
The beneficial effects of the invention are as follows：
1. positive plate uses compression molding process, it is ensured that the fit dimension uniformity of increase anticreep convex tendon.
2. W ends buckle-type protection cap uses injection molding process, interior six sides anti-rotation groove in buckle-type protection cap and fall
Buckle structure effectively prevents nut rotation, the risk to come off.
3. the W ends of W end nuts and support connection plate rack is loose fit, when using tie down screw at W ends, the circle of nut
The heart can align according to connection sheet central hole location adjust automatically, ensure installation reliability.
4. the W ends of W end nuts and support connection plate rack is loose fit, it is ensured that the cooperation of W ends connection sheet height
Dimensional uniformity.
