Abstract
The invention discloses a press-mounting automobile rectifier with excitation diodes, which consists of a positive plate, a negative plate, a forward rectifier diode assembled on the positive plate in an interference way, a reverse rectifier diode assembled on the negative plate in aninterference way, a plastic support, an insulation bushing and hollow rivets. The leading wire of the excitation diode is connected with the terminal of the corresponding insert on the plastic support; the positive plate and the negative plate are separated by the insulation bushing and are arranged on the plastic support; the hollow rivets penetrate through the plastic support and fix the negative plate in rivet connection; the leading wire of each rectifier diode is connected with the terminal of the corresponding insert on the plastic support. The invention has the advantages that the rectifier diodes are assembled in press-mounting interference fit so that welding points can not disconnect due to heating, thereby avoiding failure of the rectifier. Both the positive plate and the negative plates are punch-formed with an aluminum plate and do not damage the chip of the rectifier diode when in interference fit with the rectifier diodes. The rectifier bridge is provided with the excitation diode, thereby lowering the cost and reducing failure rate.
Description
Technical field
The present invention relates to a kind of auto rectifier, particularly a kind of press-mounting automobile rectifier of Japan electric coating series band excitation diode.
Background technology
At present, existing Japan electric coating series automobiles rectifier is the rectifier that the soldering formula does not have excitation diode, and the overall structure of this rectifier is semicircle, mainly is made of support, rectifier diode, positive plate and negative plate.Prop up positive plate and negative plate material and be red copper.There is following problem in this rectifier always when reality is used:
1. the rectifier diode of rectifier adopts soldering to be connected with positive plate, negative plate, can produce a large amount of heat when rectifier is worked on automobile, and the soldering solder joint at high temperature melts easily and throws off, and causes whole defective rectifier.
2. the positive plate of rectifier and the equal red copper of negative plate material cause the cost of rectifier higher, do not have the market competitiveness.
3. do not have excitation diode on the rectifier, can only use with the multifunction regulator combo during use, the electronic circuit of multifunction regulator is complicated, electronic original part is more, so the multifunction regulator price is expensive, and failure rate is higher, therefore leading this, to cause the rectifier scope of application less.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of press-mounting automobile rectifier with excitation diode is provided.It is to increase excitation diode in auto rectifier, at the inner metal inserted piece that increases of rectifier bracket, to form the excitation diode circuit.
The present invention is achieved through the following technical solutions: a kind of press-mounting automobile rectifier with excitation diode, by positive plate, negative plate, be assemblied in the forward rectifier diode on the positive plate, reverse rectifier diode, plastic stent, insulating bushing and the tubular rivet that is assemblied on the negative plate formed, it separates described positive plate, negative plate and is contained on the plastic stent with insulating bushing, pass plastic stent and negative plate riveted and fixed with described tubular rivet; It is characterized in that: three excitation diodes are housed, and corresponding mold insert terminal is continuous on its lead-in wire and the described plastic stent on auto rectifier.Described positive plate, negative plate are the aluminium sheet punch forming, are provided with rectifier installing hole and rectifier diodes pilot hole and ventilation hole above, and positive plate, negative plate and rectifier diode assemble in the mode of interference fit.Described forward rectifier diode and reverse rectifier diode are the pressing type diode, have axial straight burr around its cylindrical, copper base, and during assembling, straight burr plays the effect of interference fit.Be provided with five metal inserted pieces in the described plastic stent, wherein four metal inserted pieces are connected with the lead-in wire of forward rectifier diode, reverse rectifier diode and excitation diode positive pole respectively, and another metal inserted piece is connected with the negative pole of 3 excitation diodes.
The present invention has the following advantages:
1. in rectifier diode when assembling, adopt and press-fit the interference fit form, need not to adopt scolding tin, can avoid welding the high-temperature damage chip, also can not cause solder joint to be heated to throw off and make defective rectifier.
2. positive/negative plate all adopts the aluminium sheet punch forming, compare cost with copper coin and reduce greatly, and the aluminium sheet material is softer, can not damage the chip of rectifier diode when assembling with the rectifier diode interference.
3. have excitation diode on the rectifier bridge, during use and single functional regulator adapted, single functional regulator electronic circuit is simple, and electronic component is few, so price is lower, the operational failure rate is lower.
