Abstract
The utility model discloses an easily-assembled electrolytic capacitor, comprising an aluminum cylinder, a casing, a core cover, a cover plate, an anode lead-out pin and a cathode lead-out pin, wherein the cover plate is arranged on the bottom of the aluminum cylinder; the casing is covered on the aluminum cylinder; the core cover is positioned in the aluminum cylinder; and the anode lead-out pin and the cathode lead-out pin are arranged on the cover plate. The electrolytic capacitor is characterized in that the outer side walls of the cover plate tightly contact the aluminum cylinder; the outer side walls of the cover plate are provided with a circular groove; the aluminum cylinder is provided with a circular inward concave part with inward radial direction; and the inward concave part is embedded in the groove. The easily-assembled electrolytic capacitor saves one bend component, has simple structure and good assembling easiness and is beneficial for controlling the size precision of the aluminum cylinder.
Description
Technical field
The utility model relates to a kind of easy assembled electrolytic capacitor.
Background technology
Traditional on the market electrolytic capacitor is by aluminum barrel, sheath body, core bag, cover plate, and just leading foot, negative leading foot are constituting, cover plate is located at the bottom of aluminum barrel, the bottom margin bending back of aluminum barrel clamps the edge of cover plate, sheath body is placed in outside the aluminum barrel, the core bag is positioned at aluminum barrel, and positive leading foot, negative leading foot are located at the cover plate place.The bottom of aluminum barrel bends kink and inner fold outside the corresponding formation in back respectively at the outer surface edge place of cover plate and the inner surface edge place of cover plate, and outer kink and inner fold clamp the edge of cover plate.The cover plate two ends of this kind capacitor all will clamp the bottom of just being fixed in aluminum barrel, and aluminum barrel has too much bending can cause uncertainty to accuracy to size, structure more complicated, assembly technical requirement height.
The utility model content
The utility model technical issues that need to address provide a kind of easy assembled electrolytic capacitor, and this kind electrolytic capacitor is simple in structure, and assembling easily.
The utility model technical solution problem can be by taking following technical scheme:
A kind of easy assembled electrolytic capacitor, comprise aluminum barrel, sheath body, core bag, cover plate, and positive leading foot, negative leading foot, cover plate is located at the bottom of aluminum barrel, and sheath body is placed in outside the aluminum barrel, the core bag is positioned at aluminum barrel, positive leading foot, negative leading foot are located at the cover plate place, and it is characterized in that: the lateral wall of cover plate closely contacts with aluminum barrel, and the lateral wall of cover plate is provided with annular groove, aluminum barrel is provided with radially inner annular recess, and recess imbeds in this groove.
The utility model technical solution problem can also further be taked following corrective measure:
The width of groove is 2mm to 5mm.
The utlity model has following technique effect:
The easy assembled electrolytic capacitor of the utility model, the lateral wall of cover plate closely contacts with aluminum barrel, and the lateral wall of cover plate is provided with annular groove, and aluminum barrel is provided with radially inner annular recess, and recess imbeds in this groove.The recess that securing cover plate only needs a bending just can securing cover plate, needs two kinks to compare with prior art, can reduce by a kink, and simple in structure, assembling is beneficial to the accuracy to size of control aluminum barrel easily.
Description of drawings
Fig. 1 is the easy assembled electrolytic capacitor of a utility model structural representation.
Embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
Embodiment: as shown in Figure 1, a kind of easy assembled electrolytic capacitor comprises aluminum barrel 1, sheath body 2, core bag 3, cover plate 4, and positive leading foot, negative leading foot, cover plate 4 is located at the bottom of aluminum barrel, sheath body 2 is placed in outside the aluminum barrel, and core bag 3 is positioned at aluminum barrel 1, and positive leading foot, negative leading foot are located at cover plate 4 places, the lateral wall of cover plate 4 closely contacts with aluminum barrel 1, the lateral wall of cover plate 4 is provided with annular groove 5, and aluminum barrel is provided with radially inner annular recess 6, and recess 6 imbeds in this groove 5.The width of groove is 2mm to 5mm.
Securing cover plate utilizes recess to realize securing cover plate.
