SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a generator is with excessive pressure self preservation protection rectifier bridge module, bottom plate and protection casing pass through injection mold one shot forming in the production and processing process, can reach sparingly process, and the bottom plate is guaranteed steadily unbending simultaneously.

In order to achieve the above object, there is provided an overvoltage self-protection rectifier bridge module for a generator, including: the LED lamp comprises a bottom plate, wherein a protective shell is fixedly connected above the bottom plate, a plurality of diodes are inserted into the protective shell, and the bottom ends of the diodes are fixedly connected with a connecting gap bridge;

fixing through holes are formed in the middle of the two ends of the bottom plate, arc-shaped lugs are inserted into the fixing through holes, and fixing plates are fixedly connected to the bottom ends of the arc-shaped lugs.

According to the overvoltage self-protection rectifier bridge module for the generator, the threaded opening is formed in the arc-shaped convex block, and the bolt is connected to the inner thread of the threaded opening in a threaded mode.

Has the advantages that:

1. compared with the prior art, the utility model discloses be provided with bottom plate and protective housing, bottom plate and protective housing pass through injection mold one shot forming in the production and processing process, can reach and save the process, and the bottom plate is guaranteed steadily not crooked simultaneously, compares in figure description 4 rectifier bridge module product processes complicacy, workman with high costs, inefficiency and the qualified not high problem of product.

2. Compared with the prior art, the utility model discloses be provided with bottom plate, fixing hole, bolt and arc lug, when needs are installed, peg graft the both ends fixing hole of bottom plate in the outside of arc lug, through bolt and screw thread mouth screw-thread fit afterwards, reach the screw-thread fastening, be difficult for droing, be convenient for through this structure damage the back to the bottom plate dismantle change and quick installation effect.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
