Description
Technical field
The present invention relates to electrode insulation technical field of sealing technology, particularly relate to the electrode insulation hermetically-sealed construction of a kind of battery or super capacitor, also relate to the assembly technology of this electrode insulation hermetically-sealed construction simultaneously and adopt the energy storage device of this electrode insulation hermetically-sealed construction.
Background technology
At present, the electrode of conventional energy storage component (comprising battery and super capacitor) draws insulation and sealing structure as shown in Figure 1, this energy storage component is by battery core 01, housing 02, electrode lead-out structure and insulating seal, housing 02 is communicated with the lower conductive of battery core 01, and electrode lead-out structure conductive communication is in the upper end of battery core 01, therefore need insulating seal every being located between electrode lead-out structure and housing, to avoid electrode lead-out structure to contact caused short circuit problem with housing 02.In concrete structure, housing 02 is processed with the distortion fold 02-1 be absorbed between end cap 03 and collector plate 04 in gap, the sealing at this distortion fold 02-1 and the housing 02 upper end open place 02-2 that turns edge is engaged in and is axially clamped on the edge, two ends up and down of end cap 03, and distortion fold 02-1 is pressed on the edge of collector plate 04, thus make between housing 02 and electrode lead-out structure, need the position of insulating to have the part of upper surface adjacent to outer peripheral face of end cap, the outer peripheral face of end cap 03, the lower surface of end cap 03 is adjacent to the part of outer peripheral face, the upper surface of collector plate 04 is adjacent to the part of outer peripheral face, the outer peripheral face of collector plate 04, therefore above-mentioned insulating seal is divided into insulated enclosure to overlap 05, middle insulated enclosure circle 06 and lower insulated enclosure cover 07, wherein going up insulated enclosure cover 05 sets up on the upper surface of end cap 03, the upper end of upper insulated enclosure cover 05 every the sealing being located at housing 02 turn edge 02-2 and end cap 03 upper surface between, lower end is every being located between the inner peripheral surface of housing and the outer peripheral face of end cap 02, middle insulated enclosure circle 06 is every being located between distortion fold 02-2 and the lower surface of end cap 03, lower insulated enclosure cover 07 is set up on the upper surface of collector plate 04, the upper end of lower insulated enclosure cover 07 every being located between distortion fold 02-2 and the upper surface of collector plate 04, lower end is every being located between the inner peripheral surface of housing 02 and the outer peripheral face of collector plate 04, thus the object of isolated electrode deriving structure and housing is reached by three insulated enclosure covers disperseing to install and insulated enclosure circle, but also because distributed insulated enclosure body structure result in energy storage device install the problem of suffering, as such energy storage device can assemble according to following installation steps:
1st step, conducts electricity collector plate 04 and battery core 01 and is solidly fixed;
2nd step, the assembly after step 1 being installed is installed in housing 02;
3rd step, is arranged on the shaft shoulder place of collector plate 04 by lower insulated enclosure cover 07;
4th step, carries out slot rolling to housing 02, and slot rolling position is diagram distortion fold 02-2 correspondence position;
5th step, carries out height shaper to housing 02, makes circular arc state during slot rolling become step state;
6th step, insulated enclosure circle 06(and O type circle in the step place of the 5th one-step forming installs);
7th step, to be connected end cap 03 in the upper end interference of collector plate 04;
8th step, installs insulated enclosure cover 05 at the shaft shoulder place of end cap 03;
9th step, carries out sealing process at the opening part of housing 02, turns edge with the sealing obtaining needing 02-1.
Therefore in existing production technology, the reason of part erection sequence must adopt three insulating seal member to combine and realize sealing and insulation; And compare with regard to production technology and it seems, in prior art, the insulation and sealing structure assembly technology operation of energy storage device is longer, production efficiency is low, and the rigging error in use occurred due to three independent insulating seal member can bring impact to the insulated enclosure performance of whole insulating seal, so that there is more potential uncertain influencing factor in energy storage device, namely the defect of any one part or the carelessness of assembling process all can cause the insulated enclosure of monomer to lose efficacy.
