Abstract
A kind of automobile current generator, comprises rectifier bridge support connection inserting part and carbon brush holder, and the end of described connection inserting part is round-meshed anti-" Z " shape structure of tool, is fastenedly connected between connection inserting part and carbon brush holder.Material due to rectifier bridge support connection inserting part is copper sheet, its end has circular hole, when generator general assembly, be fastenedly connected with bolt and securing member thereof and carbon brush holder and instead of traditional bow-shaped shrapnel formula and contact and connect, can eliminate and time of contact of the bow-shaped shrapnel of beryllium-bronze material and carbon brush holder longly occur that elastic force fatigue failure causes the phenomenon of rupture of loose contact, thus extend generator useful life, reduce its cost, when rectifier bridge support brace can also be allowed to be connected with carbon brush holder, assembly process is simpler.
Description
Technical field
The utility model relates to auto parts and components, particularly a kind of automobile current generator.
Background technology
Automobile generator rectifier bridge support is automobile current generator center parts, it is by connecting to form generator commutation bridge to positive/negative plate and the electronic component such as corresponding diode and triode, when generator general assembly, rectifier bridge is that the bow-shaped shrapnel of 0.6 millimeter of beryllium-bronze material is connected conducting with carbon brush holder touch type by thickness, and the bow-shaped shrapnel of beryllium-bronze material is connected conducting and there are some defects with carbon brush holder:
(1) bow-shaped shrapnel of beryllium-bronze material is connected conducting in long-time use procedure with carbon brush holder, and shell fragment has tired elastic failure phenomenon, causes circuit not smooth and occurs open circuit.
(2) bow-shaped shrapnel and the carbon brush holder of beryllium-bronze material connect conducting is to be touched with carbon brush holder by arcuate front face flexure plane to contact conducting, generator has vibrations in the course of the work, touch and a little have fever phenomenon to cause carbon brush holder performance impairment, shorten generator useful life.
(3) beryllium-bronze needs just can have perfect elasticity through Overheating Treatment, heat-treat condition requires harsh, guarantee that heat treatment evenly just can make shell fragment have desirable elastic performance, and connection inserting part structure is more complicated, the high position of aeroelastic requirements is again at wedge angle position, flexible too high brittle failure phenomenon and the inadequate phenomenon of the too small elastic force of elasticity, have a strong impact on serviceability.
(4) beryllium-bronze is expensive, and cost is higher, and support cost performance is too low.
Summary of the invention
The purpose of this utility model is the deficiency overcoming automobile generator rectifier bridge support connection inserting part in prior art, provides a kind of automobile current generator, its longer service life.
The technical solution of the utility model is: a kind of automobile current generator, comprises rectifier bridge support connection inserting part and carbon brush holder, and the end of described connection inserting part is round-meshed anti-" Z " shape structure of tool, is fastenedly connected between connection inserting part and carbon brush holder.
As preferably, described rectifier bridge support connection inserting part adopts copper sheet to be made.
As preferably, be bolted between described connection inserting part and carbon brush holder.
Material due to rectifier bridge support connection inserting part is copper sheet, and its end has circular hole, when generator general assembly, is fastenedly connected instead of traditional bow-shaped shrapnel touch type and be connected with bolt and securing member thereof and carbon brush holder, desirable following technique effect:
(1) eliminate and time of contact of the bow-shaped shrapnel of beryllium-bronze material and carbon brush holder longly occur that elastic force fatigue failure causes the phenomenon of rupture of loose contact.
(2) generator useful life can be extended.Rectifier bridge support connection inserting part adopts bolt and securing member thereof and carbon brush holder to be fastenedly connected, and carbon brush holder can be protected to be without prejudice, thus prolongation generator useful life.
(3) red copper does not need Elastic Contact, does not also need heat treatment, and the toughness of red copper and the conduction of electric current are all superior to beryllium-bronze, does not have the possibility causing brace brittle failure because heat treatment is uneven.
(4) price of red copper only has 1/3rd of beryllium-bronze, and the material cost of support saves 67%.Cost performance significantly improves.Removing has more fastening bolt, pad, and total cost saves 38%.
(5) when rectifier bridge support brace is connected with carbon brush holder, assembly process is simpler.
Accompanying drawing explanation
Fig. 1 is the bow-shaped shrapnel schematic diagram of traditional beryllium-bronze material;
Fig. 2 is the schematic diagram of the utility model rectifier bridge support connection inserting part.
Embodiment
As shown in Figure 2, a kind of automobile generator rectifier bridge support connection inserting part, employing thickness is that the copper sheet of 0.8 millimeter is made, and its end is anti-" Z " shape structure 1 with circular hole 2.When generator general assembly, with bolt and securing member thereof, connection inserting part and carbon brush holder are fastenedly connected, thus substitute traditional bow-shaped shrapnel touch type connection (as shown in Figure 1).
Claims (2)
1. an automobile current generator, comprise rectifier bridge support connection inserting part and carbon brush holder, it is characterized in that, the end of described connection inserting part is for having anti-" Z " shape structure (1) of circular hole (2), be fastenedly connected between connection inserting part and carbon brush holder, described rectifier bridge support connection inserting part adopts copper sheet to be made.
2. automobile current generator according to claim 1, is characterized in that, is bolted between described connection inserting part and carbon brush holder.
