Abstract
The utility model provides an anode and cathode same-end leading-out cover of a capacitor, which comprises a foundation plate, a special-shaped rivet, a sealing ring, a sealing gasket and a stainless steel gasket. The foundation plate is provided with a center hole and a turn-up flange, the special-shaped rivet sequentially penetrates through the sealing ring, the center hole of the foundation plate, the sealing gasket and the stainless steel gasket to rivet the same integrally, the special-shaped rivet is a step cylinder, two ends of the special-shaped rivet are laser-weldable planes, and a cylindrical surface of the step cylinder is provided with a riveting ring with a turn-up riveting function, wherein the outer diameter of the riveting ring is cylindrical while the inner diameter of the riveting ring is conical. The anode and cathode same-end leading-out cover not only guarantees same-end leading-out of an anode and a cathode of the capacitor, but also guarantees isolation and sealing property between the anode and the cathode which are in high current. In addition, the anode and cathode same-end leading-out cover not only is simple in process, but also is stable in property and low in cost, and is particularly adaptable to high-current and anode and cathode same-end leading-out capacitors.
Description
Technical field
The utility model relates to the capacitor arrangement field, and particularly a kind of capacitor positive and negative electrodes in same end is drawn lid.
Background technology
When present cylindrical ultracapacitor is drawn at big electric current both positive and negative polarity, what usually adopt is to carry out both positive and negative polarity respectively in capacitor top and bottom to draw, because the ultracapacitor that heterodoxy is drawn can only carry out horizontal installation, take a large amount of installing spaces on the one hand, can not provide a good cooling platform that ultracapacitor is dispelled the heat on the other hand.And many ultracapacitors are subjected to the restriction of locus when using, and can only be made as the capacitor of drawing with end, and its exit mostly is welding and draws, and is limited by current energy, easily heating, and thermal diffusivity is bad, and complex manufacturing technology, unstable properties.
Summary of the invention
The purpose of this utility model provides that a kind of structure and technology are simple, lid is drawn in stable performance, capacitor positive and negative electrodes in same end that cost is low.
The utility model is that to address the above problem the technical scheme that adopts be that a kind of capacitor positive and negative electrodes in same end is drawn lid, comprises soleplate, special-shaped rivet, sealing ring, seal washer and stainless steel packing ring, and its innovative point is:
A, soleplate have centre bore and flange flange;
B, special-shaped rivet pass sealing ring successively, and the centre bore of soleplate, seal washer and stainless steel packing ring are riveted into one then;
C, special-shaped rivet are stepped cylinder, but two ends are the plane of laser welding, have on the face of cylinder of stepped cylinder flangable riveted joint function, external diameter is that cylinder, internal diameter are the riveted joint ring of cone.
Described sealing ring is that cross section has protruding super O RunddichtringO.Described seal washer be injection mo(u)lding, edge has the ring-type profile gasket of step.
The utility model is owing to utilized the special-shaped rivet of the riveted joint ring with flangable function, by sealing ring and seal washer with rivet and soleplate isolated insulation, sealing, the as a whole lid of riveted joint behind the company's of refilling stainless steel packing ring, the rivet both ends of the surface are respectively the inside and outside solder side of capacitor, anodal exit as capacitor, and the flange flange of soleplate, can weld with the housing of capacitor, negative pole exit as capacitor, so both guaranteed that capacitor positive and negative electrodes in same end drew, because the effect of sealing ring and seal washer has guaranteed isolation and the sealing between the big electric current both positive and negative polarity, this structure not only structural manufacturing process is simple again, and stable performance, cost is low, is specially adapted to big electric current, and the capacitor product that the positive and negative electrodes in same end is drawn uses.
Description of drawings
Fig. 1 is the structural representation that the utility model capacitor positive and negative electrodes in same end is drawn lid;
Fig. 2 is that Fig. 1 assembles explosive view before riveted joint.
Embodiment
The embodiment that provides below in conjunction with accompanying drawing describes in further detail the utility model.
Referring to Fig. 1,2, a kind of capacitor positive and negative electrodes in same end is drawn lid, comprises soleplate 1, special-shaped rivet 2, sealing ring 3, seal washer 4 and stainless steel packing ring 5, and soleplate 1 has centre bore 1-1 and flange flange 1-2; Special-shaped rivet 2 passes sealing ring 3 successively, and the centre bore 1-1 of soleplate 1, seal washer 4 and stainless steel packing ring 5 are riveted into one then; Special-shaped rivet 2 is a stepped cylinder, but two ends are plane 2-1, the 2-2 of laser welding, have on the face of cylinder of stepped cylinder flangable riveted joint function, external diameter is that cylinder, internal diameter are the riveted joint ring 2-3 of cone.
Adopt this structure to draw lid with the capacitor positive and negative electrodes in same end of special-shaped rivet 2 riveted joints, the flange flange 1-2 place of its soleplate 1 can carry out laser welding as the capacitor anode exit with capacitor casing, and the both ends of the surface 2-1 of special-shaped rivet 2,2-2 lay respectively at the interior outer end of capacitor, provide the laser welding face, as the capacitor anode exit.
Referring to Fig. 2, isolate in order to guarantee special-shaped rivet 2 and soleplate 1, improve sealing property and insulation property, described sealing ring 3 is protruding super O RunddichtringO for cross section has.Described seal washer 4 for injection mo(u)lding, edge has the ring-type profile gasket of step.
Referring to Fig. 1,2, the utility model in use, special-shaped rivet 2 passes sealing ring 3, soleplate 1, seal washer 4 and stainless steel packing ring 5 successively, and riveted joint becomes capacitor positive and negative electrodes in same end and draws lid, soleplate 1 and special-shaped rivet 2 are relative isolates, insulate, the flange flange 1-1 that soleplate 1 has can carry out laser welding with capacitor casing, as the negative pole exit of capacitor, the both ends of the surface of special-shaped rivet 2 lay respectively at inside and outside of capacitor and can be respectively carry out the anodal exit that its outer face of laser welding can be used as capacitor with the collector of inside and outside portion.Realized the purpose that the positive and negative electrodes in same end is drawn.Owing to adopted the lobed O RunddichtringO 3 and the injection mo(u)lding of particular design, edge has the ring-type profile gasket 4 of step, sealing and insulation property have been improved, when riveted joint, the special upper surface of stainless steel packing ring 5 that guarantees is after the riveted joint of the riveted joint ring 2-3 place of special-shaped rivet 2, and the distance between the riveted joint lower surface of special-shaped rivet 2 is in setting, after can guaranteeing that the utility model and capacitor are welded as a whole, carry out that helium leak check reaches designing requirement under the high/low temperature condition, this performance is the long-time use of ultracapacitor and uses under cold or extremely hot condition and established technical foundation, therefore, capacitor positive and negative electrodes in same end of the present utility model is drawn lid and is had structure, technology is simple, stable performance, the advantage that cost is low.
