Abstract
Low impedance condenser, including casing, apron, lead wire, be equipped with the riveting hole on the lead wire, the lead wire passes through rivet connection with the apron, the rivet penetrates into riveting hole, its characterized in that: be equipped with the flange on the riveting hole, the flange is the narrow conical surface under the width, the flange is equipped with the direction grooving with the junction of lead wire. Through be equipped with the flange on riveting the hole, can suitably enlarge lead wire riveting hole diameter to increase riveting petal area of contact increases the riveting degree and the ductility that go between with the aluminium foil, reduces the product impedance, riveting point intensity is high in addition, the riveting steady quality, and the anti striking ability of product obtains improving, and the practical life of product is long.
Description
Technical field
The utility model belongs to electrolytic capacitor and manufactures field, is specifically related to low-impedance capacitor.
Background technology
Capacitor as the important electronic devices and components of electricity-saving lamp application, the impedance of capacitor as one of the important parameter of aluminium electrolytic capacitor, under same frequency, impedance is lower, electricity-saving lamp caloric value is lower, and bear resistance to ripple current larger, useful life is longer.The staking process quality of capacitor affects riveted degree and the ductility of lead-in wire and aluminium foil to a certain extent, and then determines the performance parameter of electrolytic capacitor.
Summary of the invention
The purpose of this utility model is to provide low-impedance capacitor, and it is simple and reasonable, significantly reduces product impedance.
The technical solution of the utility model is: a kind of low-impedance capacitor, comprise housing, cover plate, lead-in wire, described lead-in wire is provided with riveted holes, described lead-in wire and cover plate pass through rivet interlacement, described rivet penetrates into riveted holes, it is characterized in that: described riveted holes is provided with flange, described flange is the conical surface wide at the top and narrow at the bottom; The junction of described flange and lead-in wire is provided with guiding grooving.
Further, described guiding grooving is arc transition form.
Beneficial effect: by being provided with flange on riveted holes, suitably can expand lead-in wire riveted holes diameter, to increase riveted joint petal contact area, increases riveted degree and the ductility of lead-in wire and aluminium foil, reduces product impedance; In addition riveting point intensity is high, and riveting quality is stablized, and the impact resistant capability of product is improved, and the physical life of product is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation gone between in embodiment.
In figure 1, housing, 2, lead-in wire, 3, cover plate, 4, rivet, 5, riveted holes, 6, flange, 7, guiding grooving.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, a kind of low-impedance capacitor, a kind of low-impedance capacitor, comprise housing 1, cover plate 3, lead-in wire 2, described lead-in wire 2 is provided with riveted holes 5, and described lead-in wire 2 is connected by rivet 4 with cover plate 3, and described rivet 4 penetrates into riveted holes 5; Described riveted holes 5 is provided with flange 6, and described flange 6 is the conical surface wide at the top and narrow at the bottom; Described flange 6 is provided with the junction of lead-in wire the grooving 7 that leads.
Further, described guiding grooving 7 is in arc transition form.
The utility model product, the contact resistance between lead-in wire and cover plate is reduced.After tested, the utility model significantly reduces the impedance of product under same frequency, and same specification product is under same frequency (10K), and resistance value have dropped 8-10%, and the resistance to ripple performance of product gets a promotion, and the life-span of product obtains and ensures more reliably.
