Abstract
The utility model belongs to capacitor components, provides a current collector of a super capacitor, and is formed by a current collector body. The current collector body comprises a main stem, a welding portion and a guide groove. The current collector of the super capacitor obtained according to the technical scheme can guarantee that the current collector is welded with convex foil tightly and firmly, and welding equivalent series resistance (ESR) value is little. The current collector of the super capacitor further guarantees that electrolyte is rapidly and sufficiently permeated into a whole core package of the super capacitor when the electrolyte is poured in super capacitor production process, and production quality and performance of the super capacitor can meet requirements.
Description
Technical field
The utility model discloses a kind of capacitor accessory, relates in particular to a kind of collector that is applicable to the ultracapacitor assembling process.
Background technology
Ultracapacitor is a kind of novel energy-storing device; Have that the speed of discharging and recharging is fast, specific power is high, have extended cycle life, plurality of advantages such as serviceability temperature wide ranges, energy-conserving and environment-protective, be widely used in fields such as automobile, wind power generation, urban light rail, subway, solar energy, UPS and heavy industry equipment at present.
In the product structure of ultracapacitor, collector is ultracapacitor utmost point group and the extraneous bridge that is communicated with, and its structure and performance have fundamental influence to the performance of ultracapacitor.In the Assembling Production technology of ultracapacitor; Collector needs and the prominent paper tinsel of utmost point group closely welds; It is little that it not only will guarantee to weld the ESR value, and intensity meets the demands, and will guarantee that more ultracapacitor is when the fluid injection operation; Therefore the whole core bag of electrolysis fluid power rapid osmotic to ultracapacitor utmost point group has proposed requirement to its structure.
Mostly conventional super capacitor collection liquid body is that sheet metal processes, and electrode is drawn difficulty, and the assembly technology difficulty is big, and if is guaranteeing that its weld strength and ESR value can not well meet the demands again under the situation that the electrolysis fluid power permeates fully.
Summary of the invention
The purpose of the utility model provides a kind of super capacitor collection liquid body of brand-new design structure; This structure not only guarantees the intensity and the low ESR value of collector and the prominent paper tinsel welding of utmost point group; Guarantee that more ultracapacitor is when the fluid injection operation; The whole core bag of electrolysis fluid power rapid osmotic to ultracapacitor guarantees that the production quality and the ultracapacitor performance of ultracapacitor meets the demands.
The utility model is for realizing above-mentioned purpose, and the technical scheme of employing is the super capacitor collection liquid body of a kind of brand new of design.Collector is made up of the collector body, and the collector body comprises the main body stem, and welding portion and guiding gutter are arranged on the main body stem.Its innovative point is: adopt the brand-new design structure, guarantee intensity and low ESR value that the prominent paper tinsel of collector and utmost point group welds, and ultracapacitor is when the fluid injection operation, the whole core bag of electrolysis fluid power rapid osmotic to ultracapacitor utmost point group.
Said super capacitor collection liquid body comprises the collector body, and wherein said collector body comprises the main body stem, and welding portion and guiding gutter are arranged on the main body stem.
Said main body stem comprises " * " type part and " excircle " part.
Said main body stem " * " type partly has 12 branches, and thickness does

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Referring to Fig. 1, the super capacitor collection liquid body of the utility model is made up of the collector body, and wherein said collector body comprises main body stem 1, and welding portion 2 and guiding gutter 3 are arranged on the main body stem 1.
The actual use of the collector of present embodiment size can be amplified or dwindles making according to the ultracapacitor size of coupling in proportion, but the ultracapacitor size diameter scope that is suitable for does
20 ~ 100Mm.Ultracapacitor utmost point core assembly bag diameter should be less than the interior diameter of main body stem excircle
0.5 ~ 5Mm.
In the present embodiment, at first should be with the prominent paper tinsel compacting of ultracapacitor utmost point core assembly bag, the super capacitor collection liquid body is close to the prominent paper tinsel face of utmost point group, carries out laser welding then.Because this collector is circular, non-directional, therefore the location is simple, convenient, but should guarantee as far as possible that super capacitor collection liquid body and ultracapacitor utmost point core assembly bag are positioned on same the axis, guarantees the homogeneity of welding and stressed homogeneity.
