Abstract
The utility model relates to the weld of the sealing device and the draining member of a capacitor, which relates to a full-closed axial aluminium electrolytic capacitor. The capacitor is composed of an outer shell (1), a core cover (2), a draining strip (3), a sealing ring (4), CP lines (6), etc. The utility model is characterized in that both ends of the capacitor are respectively provided with a concave outer cap (5) which is capable of welding with the draining strip (3) and the CP lines (6), and the outer cap (5) is inserted in the sealing ring (4) provided with a groove. The capacitor is simple and feasible, the weld of the draining member is convenient and reliable, and the sealing and service performance is good. The utility model has a specific significance for the improvement of the quality of the products, and the capacitor is suitable for sounders and other electric appliances.
Description
The utility model relates to the sealing device of relevant capacitor and the welding manner of drainage part, belongs to the axial aluminium electrolytic capacitor of a kind of totally enclosed type, and it all has favorable applicability to multiple stereo set and electric equipment products thereof.
Existing axial aluminium electrolytic capacitor generally is made of shell, core bag, drainage strip, sealing ring and CP line.In the prior art, in order to improve the sealing of capacitor two terminations, the usual way that adopts the thickening elastic tape, but because all there is longitudinal groove in various degree in lead-out wire, the early failure problem that is difficult to realize effectively sealing and very easily causes capacitor, the welding of its drainage part of prior art still owes reliable in addition.
The utility model is intended to overcome the problems referred to above with not enough, proposes a kind of simple and reliablely, promptly is convenient to the welding of drainage part, can guarantee the axial aluminium electrolytic capacitor of reliable sealing totally enclosed type again.
Concrete structure of the present utility model is described in detail as follows to technology contents: this device structure is similar substantially to existing product, and it is made of bilateral shell (1), core bag (2), drainage strip (3), sealing ring (4), CP line (6) etc.The main points of its architecture advances are, all are equiped with one at these device two ends and can weld the aluminium matter outer end cap (5) that drainage strip (3) and CP line (6) and shape are concavity, and outer end cap (5) is inlaid in the thin type sealing ring (4) that has a groove.
When adopting the utility model, earlier means of spot welds (ultrasonic bonding) is carried out at core bag drainage strip (3) and outer end cap (5) medial surface center, CP line (6) and outer end cap (5) lateral surface central point are welded even; Then above-mentioned member is embedded in its groove of sealing ring (4), at last above-mentioned parts are pushed in the bilateral shell (1), two terminal tool crimpings can be realized totally-enclosed encapsulation.Sealing ring among the figure (4) outside can produce some normal deformation because of mechanical crimp.
The structural representation of accompanying drawing 1, the axial aluminium electrolytic capacitor of totally enclosed type
The A-A cut-away view of accompanying drawing 2, accompanying drawing 1
The utility model is compared with prior art: not only simple possible, structure Rationally, and drainage part convenient welding is reliable, sealing and serviceability is good, Has specific meaning for the quality of improving this series products.
