Abstract
The utility model discloses an automobile rectifier positive and negative plate riveted-fixing structure. The structure comprises a backing plate, a negative plate, an iron hollow rivet, a bridge support, and a positive plate. The structure is characterized in that an epoxy pad is arranged in the connection place of the bridge support and the positive plate; the iron hollow rivet penetrates through the epoxy pad and passes through the bridge support, and then connects the positive plate with the bridge support in a rotary riveting manner; and the backing plate is arranged on the negative plate, and the riveted positive plate and bridge support are in interference fit with the negative plate through bumps on the bridge support. The structure is advantaged in that the negative plate, and the positive plate, the support, and the rivet are riveted and fixed separately so that the poor heat dissipation caused by contact failure can be prevented effectively; and the generator output instability caused by loosening of an output screw rod due to loosening of locking of the positive plate can be also prevented.
Description
Technical field
The utility model relates to a kind of auto parts machinery, is specifically related to a kind of auto rectifier positive/negative plate and rivets fixing structure.
Background technology
Rivet fixedly positive/negative plate can play effective fixed effect, and negative plate coordinates basic laminating with end cap, and radiating effect can meet product user demand substantially.At present, in the middle of existing rivet, contain support (PPS), screw rod protective sleeve (PA66), these plastic materials shrink because itself performance factor there will be product in high chilling process, and remain in certain gap after rivet negative plate and between end cap; The bad phenomenon such as the contraction of product can cause that loosening, the radiating effect between matching loose, rivet and other mating parts of pole plate and end cap reduces, rectifier is loosening in use procedure.Long-time vibrations and high low temperature destructions that easily riveted joint screw rod fractureed, causes rectifier to become flexible, and when rivet is subject to external impacts or vibrates for a long time, is easy to rotate or becomes flexible like this, thereby causing the loose contacts such as rivet and positive plate, negative plate.
Above problem causes generator when work, to have following problem:
1. the fixing and heat radiation of positive/negative plate is the necessary condition that guarantees the normal work of each power consumption equipment of automobile, during generator work, having very large electric current passes through, when rivet contacts with positive plate when loosening, can produce very large virtual connection and sparking risk, thereby make positive plate and wait very large heat and the brittle failure hidden danger of junction generation, finally cause generator cisco unity malfunction.
2. in addition, when negative plate and end cap loose contact, positive plate causes output screw to become flexible (output screw is fixed on positive plate) when loosening, also can cause that generator heat-radiation is bad, output current is unstable, finally cause vehicular electrical appliance cisco unity malfunction or Yin Gaowen to damage.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of prior art, provides a kind of auto rectifier positive/negative plate to rivet fixing structure.This auto rectifier positive/negative plate rivets that fixing structure will be born plate and positive plate, support, rivet flog are fixed, and can effectively avoid the heat radiation that produces because of loose contact bad; And avoid exporting unstable because of the loosening output screw causing of positive plate locking generator loosening and then that cause.
The purpose of this utility model is achieved in that a kind of auto rectifier positive/negative plate rivets fixing structure and comprise backing plate, negative plate, iron tubular rivet, bridge bracket, positive plate, it is characterized in that: in the junction of bridge bracket and positive plate, be provided with epoxy pad, iron tubular rivet passes through bridge bracket through epoxy pad, and by revolving the mode of riveting, positive plate and bridge bracket is riveted together.Backing plate is housed on negative plate.The positive plate being riveted together and bridge bracket are by salient point on bridge bracket and negative plate interference fit.
Described iron tubular rivet directly withstands negative plate, with screw rod, is locked.
Its beneficial effect is: due to iron tubular rivet and negative plate are separated to assembling, with iron tubular rivet, directly withstand negative plate, then with screw rod, be locked, can make coordinating between rectifier and end cap really play hardwired assembling, can avoid the gap between loosening and negative plate and the end cap of screw rod to produce, negative plate and end cap are mounted with by effective locking, avoid producing virtual connection because positive plate is loosening or dispel the heat bad, and the generation of avoiding the wild effects such as generator output current that cause because of screw bolt loosening.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is that the auto rectifier of new technique is riveted fixedly assembling front view;
Fig. 2 is the left view of Fig. 1.
In figure: the 1st, backing plate, the 2nd, negative plate, the 3rd, bridge bracket, the 4th, epoxy pad, the 5th, iron tubular rivet, the 6th, positive plate.
embodiment
In seeing figures.1.and.2, the utility model comprises backing plate 1, negative plate 2, iron tubular rivet 5, bridge bracket 3, positive plate 6, in bridge bracket 3 and the junction of positive plate 6, be provided with epoxy pad 4, iron tubular rivet 5 is riveted together product by revolving the mode of riveting by bridge bracket 3 through epoxy pad 4 again; In addition, first backing plate 1 is assembled on negative plate to 2, then by above semi-finished product by salient point and negative plate 2 interference fit on bridge bracket 3, then by bearing the welding of single tube, above all parts are fixed together.
Claims (2)
1. an auto rectifier positive/negative plate is riveted fixing structure, comprise backing plate, negative plate, iron tubular rivet, bridge bracket, positive plate, it is characterized in that: in the junction of bridge bracket and positive plate, be provided with epoxy pad, iron tubular rivet, is riveted together positive plate and bridge bracket by revolving the mode of riveting by bridge bracket through epoxy pad; On negative plate, be provided with backing plate, the positive plate being riveted together and bridge bracket are by salient point on bridge bracket and negative plate interference fit.
2. auto rectifier positive/negative plate according to claim 1 is riveted fixing structure, it is characterized in that: described iron tubular rivet directly withstands negative plate, with screw rod, is locked.
