Description
Technical field
The utility model relates to a kind of rivet, and particularly a kind of rivet for capacitor, belongs to capacitor assembly field.
Background technique
Current capacitor is widely used in fields such as power electronics, communications service and rail transport, in most of capacitor, the Copper Foil of electrode tip, explosion-proof fast, millboard, seal ring and upper capacitor cover is coupled together usually through rivet.Such as, often can heat occur and can not discharge in time in capacitor, after long-time use, capacitor casing produces dilatancy to a certain degree, and then causes capacitor inner assembly generation dislocation in various degree, causes the rivet connecting each assembly to twist.The nail bar of common rivet is round column structure, and can rotate because of distortion power in connection procedure, fixed effect is poor, therefore in capacitor assembly field, usually can use the rivet preventing from reversing.
Fig. 1 is applied to the rivet that in capacitor, each assembly connects in prior art, this rivet comprises end 11, nail bar 12, the head of a nail 13 and head 14, side near end 11 between nail bar 12 and the head of a nail 13 is provided with two stiffening ribs 15, the design of this additional stiffening rib 15 needs supporting millboard as shown in Figure 2, this cardboard comprises plate body 1, plate body 1 is provided with the through hole 2 running through plate face, through hole 2 bilateral symmetry is provided with the bar hole 3 running through plate face, and bar hole 3 and through hole 2 are interconnected.During use, the nail bar 12 of rivet passes through hole 2, the stiffening rib 15 of rivet and the bar hole 3 phase coadaptation of millboard of millboard.The rivet of this structure can be subject to the constraint of bar hole 3 and can not twist.But because two stiffening ribs 15 are in together in a plane, when rivet be subject to along two stiffening ribs 15 torsion in the plane time, rivet still produces the displacement of stiffening rib 15 in-plane, and fixed effect is bad.
Model utility content
The deficiency that the utility model exists for prior art, provide the comprehensive rivet for capacitor avoiding rivet rotation, movement of a kind of energy, concrete technological scheme is as follows:
A kind of rivet for capacitor, described rivet comprises end, nail bar and head, position near head on described nail bar is provided with the head of a nail, the head of a nail is vertical with nail bar near the face of end, nail bar with contact between the head of a nail and be provided with the stiffening rib of more than three or three near the side of end, described stiffening rib is uniformly distributed along the surface circumference of following closely bar.
As the improvement of technique scheme, described stiffening rib has chamfering away from the side of nail bar and the head of a nail.
As the improvement of technique scheme, described stiffening rib surface is provided with protuberance.
As the improvement of technique scheme, described protuberance be bottom surface at stiffening rib on the surface, summit is away from the pyramid of stiffening rib.
As the improvement of technique scheme, described protuberance be bottom surface at stiffening rib on the surface, upper surface is away from the convex parts of stiffening rib.
As the improvement of technique scheme, described convex parts is pyramid.
Technique scheme improves the fixed effect of rivet by the stiffening rib increasing rivet, rivet can be made when being subject to the torsion in all directions, symmetrical stiffening rib can uniform stressed, make to combine closely between rivet and millboard, thus reach good fixed effect, overall structure is symmetrical simultaneously, is convenient to Mechanized Processing, has useful technique effect and reliable use value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the rivet for capacitor in background technique;
Fig. 2 be in background technique in capacitor with the structural representation of the millboard of rivets;
Fig. 3 is the structural representation of a kind of rivet for capacitor of the utility model.
Embodiment
As shown in Figure 3, described rivet comprises end 11, nail bar 12 and head 14, end 11 and head 14 are all with chamfering, chamfering structure is conveniently fixed on the corresponding assembly of capacitor, position near head 14 on described nail bar 12 is provided with the head of a nail 13, the head of a nail 13 is vertical with nail bar 12 near the face of end 11, the head of a nail 13 can limit rivet and move to millboard further on the direction along nail bar, nail bar 12 with contact between the head of a nail 13 and be provided with the stiffening rib 15a of more than three or three near the side of end 11, stiffening rib 15a is uniformly distributed along the surface circumference of nail bar 12, the distributed architecture one of this stiffening rib 15a is conveniently rivet processing, two is to make rivet overall structure symmetrical, thus when being subject to torsion each position stress balance, reach more stable firmly effect.In entirety, the rivet of the program due to the number of stiffening rib 15a many compared with existing rivet, therefore need to make the millboard adapted with rivet in the technical program, this rivet arrangement is in the process that millboard coordinates, and can bear the torsion in all directions and does not rotate or move.
In the above-described embodiments, in order to make rivet be inserted to smoothly in millboard, away from nail bar 12, chamfering 16 can be set at stiffening rib 15a with the side of the head of a nail 13.Simultaneously, protuberance 20 can be set on stiffening rib 15a surface, increase the frictional force between stiffening rib 15a surface and millboard, adopt the rivet designing protuberance 20 on stiffening rib 15a, can after stiffening rib 15a be inserted to millboard, make to combine between stiffening rib 15a and millboard more tight, avoiding at rivet when being subject to along nail bar to power on head 14 direction, causing loosening between rivet and millboard.
In the above-described embodiments, protuberance 20 can adopt the structure of pyramid, the bottom surface of pyramid at stiffening rib 15a on the surface, the summit of pyramid is away from stiffening rib 15a, adopt the rivet of this structure when fixing, the top of icicle can be embedded in millboard, further limit the relative movement between rivet and millboard.Simultaneously, protuberance 20 pages can adopt other any one bottom surfaces at stiffening rib 15a on the surface, upper surface is away from the convex parts of stiffening rib 15a structure, such as adopt pyramid, because these structures can increase the area of contact between stiffening rib 15a and millboard, and then the frictional force increased between the two, reach the object of both restrictions relative movement.
