Abstract
The utility model discloses a rivet for welding an anti-explosion cover of a power capacitor. The rivet for welding the anti-explosion cover of the power capacitor comprises a metal round piece. Groove patterns are arranged on the upper surface and the lower surface of the metal round piece. A rivet rod is fixed in the middle of the metal round piece and comprises a cylindrical part and a cone-shaped part. An end portion of the cone-shaped part of the rivet rod is provided with a cross-shaped notch. According to the rivet for welding the anti-explosion cover of the power capacitor, the cross-shaped notch or a cross-shaped insertion groove is formed in the end portion of the round and smooth end of the rivet and copper foil is prevented from being disengaged when the rivet is used, the rivet is not easily torn from the anti-explosion cover in the time of explosion, excessively early explosion is prevented and the rivet is safe and reliable in use and high in practicability.
Description
Technical field
The utility model relates to electric capacitor Explosion-proof cap technical field, relates in particular to a kind of rivet of weld power electric capacity Explosion-proof cap.
Background technique
In the process that the electric capacitor Explosion-proof cap is made, rivet is used for welding insulation terminal and wiring lug, in the time of will detonating when meeting accident, the electric capacitor Explosion-proof cap can be torn with rivet, insulated terminal and inserted sheet and separate, and the end of rivet of the prior art is round and smooth, such rivet when detonating, be easy to tear with anti-riot lid, can not play the effect that extends the burst time, and in use, Copper Foil comes off easily.
The model utility content
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of rivet that effectively prevents the weld power electric capacity that detonates too early Explosion-proof cap is provided.
The utility model is achieved through the following technical solutions:
A kind of rivet of weld power electric capacity Explosion-proof cap, include metal disk, the upper and lower surface of metal disk is equipped with the groove lines, be fixed with the rivet rod in the middle of described metal disk, described rivet rod includes cylindrical part and tapering part, in the end of the tapering part of described rivet rod, has the cross breach.
Described cross breach also can be the cross slot.
The utility model has the advantages that: the utility model has cross breach or cross slot by the end of the round and smooth end at rivet, can prevent that so in use Copper Foil from coming off, and be not easy while detonating to tear with Explosion-proof cap, can prevent from detonating too early, safe and reliable, practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of rivet of weld power electric capacity Explosion-proof cap, include metal disk 1, the upper and lower surface of metal disk 1 is equipped with groove lines 5, be fixed with rivet rod 2 in the middle of described metal disk 1, described rivet rod 2 includes cylindrical part and tapering part 4, in the end of the tapering part 4 of described rivet rod 2, has cross breach 3.
Described cross breach 3 also can be the cross slot.
Claims (2)
1. the rivet of a weld power electric capacity Explosion-proof cap, it is characterized in that: include metal disk, the upper and lower surface of metal disk is equipped with the groove lines, be fixed with the rivet rod in the middle of described metal disk, described rivet rod includes cylindrical part and tapering part, in the end of the tapering part of described rivet rod, has the cross breach.
2. the rivet of a kind of weld power electric capacity Explosion-proof cap according to claim 1, it is characterized in that: described cross breach also can be the cross slot.
