Abstract
The utility model relates to a rivet for condenser belongs to capacitor bank spare technical field, including tip, nail pole and head, the position that is close to the head on the nail pole is provided with the head of a nail, and the face that the head of a nail is close to the head is perpendicular with the nail pole, the position that nail pole surface is close to the head of a nail is provided with a plurality of stupefied, stupefied sets up along nail pole axial. The rivet that this technical scheme provided is when using, the head that to follow closely the pole passes the through -hole of hard board, stupefied on the nail pole will be blocked in the through -hole, improve the area of contact between the through -hole on nail pole and the hard board, contact friction power has between the two been increased, thereby reach restraint rivet pivoted effect, the rivet that adopts above -mentioned structure simultaneously is during with the hard board cooperation, no longer need artifical the alignment, and improves the production efficiency, beneficial effect is showing, and need not not set up the bar hole on the hard board, and saves manufacturing cost, thus the device has a broad market prospec.
Description
Technical field
The utility model relates to a kind of rivet, and particularly a kind of rivet for capacitor, belongs to capacitor assembly technical field.
Background technique
Capacitor is a kind of element can storing electric charge, is also one of the most frequently used electronic component, is widely used in fields such as power electronics, communications service and rail transport.The Copper Foil of electrode tip, explosion-proof fast, millboard, seal ring and upper capacitor cover are generally coupled together by rivet by common capacitor; the nail bar of common rivet is round column structure; can rotate because of distortion power in connection procedure; fixed effect is poor; therefore in capacitor assembly field, the rivet preventing from reversing can usually be used.
Fig. 1 is the structural representation of rivet in prior art, this rivet is by end 10, the head of a nail 20 and nail bar 40 form, side away from end 10 between nail bar 40 and the head of a nail 20 is provided with two stiffening ribs 30, the structural representation of millboard of Fig. 2 for using with the rivets shown in Fig. 1, this millboard comprises plate body 1 and the through hole 2 running through plate face and the bar hole 3 be connected with through hole 2, in Capacitor banks process of assembling, the nail bar 40 of rivet passes the through hole 2 of millboard, stiffening rib 30 is registered to bar hole 3, the constraint that rivet is subject to bar hole 3 cannot freely be rotated, reach fixing effect.But find during actual use, the rivet of this structure and millboard need manual-alignment when assembling, and manufacturing efficiency is lower.
Summary of the invention
For solving problems of the prior art, the utility model provide a kind of need not the rivet for capacitor of manual-alignment, concrete technological scheme is as follows:
A kind of rivet for capacitor, comprise end, nail bar and head, the position near head on described nail bar is provided with the head of a nail, and the head of a nail is vertical with nail bar near the face of head, described nail bar surface is provided with multiple stupefied bar near the position of the head of a nail, and described stupefied bar is axially arranged along nail bar.
As the improvement of technique scheme, described stupefied bar has oblique muscle near the side of head.
As the improvement of technique scheme, described stupefied bar is provided with bladed protuberance away from the side of nail bar.
As the improvement of technique scheme, the described head of a nail is provided with pyramid near the side of stupefied bar.
As the improvement of technique scheme, described pyramid is evenly distributed on head of a nail surface.
The rivet that technique scheme provides in use, by the through hole of the head of nail bar through millboard, stupefied bar on nail bar will snap in through hole, improve the area of contact between the through hole on nail bar and millboard, increase contact friction force between the two, thus reach the effect of constraint rivet rotation, when adopting the rivet of said structure to coordinate with millboard simultaneously, no longer need manual-alignment, improve manufacturing efficiency, beneficial effect is remarkable, and millboard need not offer bar hole, save manufacture cost, wide market.

Embodiment
As shown in Figure 3, the utility model provides a kind of rivet for capacitor, comprise end 10, nail bar 40 and head 41, position near head 41 on described nail bar 40 is provided with the head of a nail 20, the head of a nail 20 is vertical with nail bar 40 near the face of head 41, described nail bar 40 surface is provided with multiple stupefied bar 50 near the position of the head of a nail 20, described stupefied bar 50 is axially arranged along nail bar 40, during use, by the through hole 2 of the head 41 of nail bar 40 through millboard as shown in Figure 2, stupefied bar 50 on nail bar 40 will snap in through hole 2, improve the area of contact between the through hole 2 on nail bar 40 and millboard, increase contact friction force between the two, thus reach the effect of constraint rivet rotation, when adopting the rivet of said structure to coordinate with millboard simultaneously, no longer need manual-alignment, improve manufacturing efficiency, and millboard need not offer bar hole 3, save manufacture cost.
Further, as shown in Figure 4, stupefied bar 50 has oblique muscle 51 near the side of head 41, and this oblique muscle 51 can play the effect of transition when the nail bar 40 of rivet is inserted in the through hole 2 of millboard, and stupefied bar 50 is progressively increased with the area of contact of through hole 2; Further, stupefied bar 50 is provided with bladed protuberance 52 away from the side of nail bar 40, and the object of this structure improves the fixed effect of stupefied bar 50 and through hole 2; Further, at the head of a nail 20, pyramid 60 can be set near the side of stupefied bar 50, the number of pyramid 60 can be multiple, be evenly distributed on the head of a nail 20 surface, when rivet contacts with millboard, pyramid 60 is embedded in millboard, increases the area of contact between the head of a nail 20 and millboard to a certain extent, with stupefied bar 50 with the use of the torsional restraint effect that can improve rivet.
