Abstract
The present invention relates to the technical field of electronic components, and in particular to an improved aluminum electrolytic capacitor which comprises an aluminum casing. The aluminum casing is wrapped with a rubber sleeve, and a core is arranged in the aluminum casing and provided with two conducting strips. An opening part of the aluminum casing is provided with a rubber plug, and the conducting strips penetrate the rubber plug and are exposed on the outer surface of the rubber plug. The conducting strips are provided with limiting structures, insulating barriers are arranged at the positions of the limiting structures, one side of each insulating barrier abuts against the limiting structure, and the other side of the insulating barrier abuts against the inner end face of the rubber plug. The conducting strips are sleeved with conductive sleeves which are connected with lead terminals. The improved aluminum electrolytic capacitor according to the present invention is provided with the conductive sleeves, and the conductive sleeves can be mounted in a last process of assembling the aluminum electrolytic capacitor. Besides, even if the lead terminals break accidentally, the conductive sleeves can also be taken out for reinstallation, thereby being favorable for improving production yield and reducing waste. The arrangement of the insulating barriers makes the conducting strips connected with the core more firmly and improves reliability of components.
Description
IMPROVED ALUMINUM ELECTROLYTIC CAPACITOR BACKGROUND
Technical Field
The present invention relates to the technical field of electronic components, and in particular to an improved aluminum electrolytic capacitor.
Related Art
An aluminum electrolytic capacitor is a commonly used electronic component and generally includes an aluminum casing. The aluminum casing is wrapped with a rubber sleeve, and a core is arranged in the aluminum casing and provided with two conducting strips which are connected with lead terminals. An opening part of the aluminum casing is provided with a rubber plug, and the lead terminals penetrate the rubber plug and are exposed on the outer surface of the rubber plug. During assembly, the rubber plug is plugged in finally. Since the lead terminals are long, the lead terminals break easily during assembly of the rubber plug, resulting in scrapping of the aluminum electrolytic capacitor. Thus, the rejection rate is high in the current process of producing the aluminum electrolytic capacitors.
Summary
Against the aforementioned shortcomings in the prior art, the objective of the present invention is to provide an improved aluminum electrolytic capacitor.
In order to achieve the aforementioned objective, the following technical solution is adopted according to the present invention:
An improved aluminum electrolytic capacitor, comprising an aluminum casing; the aluminum casing is wrapped with a rubber sleeve, and a core is arranged in the aluminum casing and provided with two conducting strips; an opening part of the aluminum casing is provided with a rubber plug, and the conducting strips penetrate the rubber plug and are exposed on the outer surface of the rubber plug; the conducting strips are provided with limiting structures, insulating barriers are arranged at the positions of the limiting structures, one side of each insulating barrier abuts against the limiting structure, the other side of the insulating barrier abuts against the inner end face of the rubber plug; and the conducting strips are sleeved with conductive sleeves which are connected with lead terminals.
Preferably, the conductive sleeves and the lead terminals are of an integrated structure.
Preferably, the limiting structures are step end faces.
Preferably, the conducting strips are provided with a plurality of protrusion structures.
Preferably, the aluminum casing is provided with grooves, and the inner walls of the grooves abut against the rubber plug.
By adoption of the aforementioned solution, the improved aluminum electrolytic capacitor according to the present invention is provided with the conductive sleeves, and the conductive sleeves can be mounted in a last process of assembling the aluminum electrolytic capacitor. Besides, even if the lead terminals break accidentally, the conductive sleeves can also be taken out for reinstallation, thereby being favorable for improving production yield and reducing waste; and the arrangement of the insulating barriers makes the conducting strips connected with the core more firmly and improves reliability of components.
