Description
Technical field
The present invention relates to the electrode insulation technical field of sealing technology, relate in particular to the electrode insulation hermetically-sealed construction of a kind of battery or super capacitor, simultaneously the energy storage device that also relates to the assembly technology of this electrode insulation hermetically-sealed construction and adopt this electrode insulation hermetically-sealed construction.
Background technology
At present, the electrode of energy storage component (comprising battery and super capacitor) commonly used is drawn insulation and sealing structure as shown in Figure 1, this energy storage component is by electric core 01, housing 02, electrode deriving structure and insulated enclosure body, the lower end conductive communication of housing 02 and electric core 01, and electrode deriving structure conductive communication is in the upper end of electric core 01, so need be with the insulated enclosure body every being located between electrode deriving structure and the housing, contacting the short circuit problem that is caused to avoid the electrode deriving structure with housing 02.In concrete structure, be processed with on the housing 02 and be absorbed in the distortion fold 02-1 in the gap between end cap 03 and the collector plate 04, the 02-2 that turns edge that seals at this distortion fold 02-1 and housing 02 upper end open place is engaged on the edge, two ends up and down that axially is clamped on end cap 03, and distortion fold 02-1 is pressed on the edge of collector plate 04, thereby make the position that between housing 02 and electrode deriving structure, needs to insulate the upper surface of end cap be arranged adjacent to the part of outer peripheral face, 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 insulated enclosure body is divided into insulated enclosure cover 05, middle insulated enclosure circle 06 and following insulated enclosure cover 07, wherein go up insulated enclosure cover 05 and set up on the upper surface of end cap 03, last insulated enclosure overlaps 05 upper end and turns edge between the upper surface of 02-2 and end cap 03 every being located at sealing of housing 02, the lower end is between the outer peripheral face of the inner peripheral surface that is located at housing and end cap 02; Middle insulated enclosure circle 06 is between the lower surface that is located at distortion fold 02-2 and end cap 03; Following insulated enclosure cover 07 is set up on the upper surface of collector plate 04, the upper end of following insulated enclosure cover 07 between the upper surface that is located at distortion fold 02-2 and collector plate 04, the lower end is between the outer peripheral face of the inner peripheral surface that is located at housing 02 and collector plate 04, thereby disperse the insulated enclosures cover of installation and the purpose that the insulated enclosure circle has reached isolated electrode deriving structure and housing by three, but also because distributed insulated enclosure body structure has caused energy storage device that the problem of suffering is installed, as such energy storage device can assemble according to following installation steps:
In the 1st step, collector plate 04 and electric core 01 conduction are solidly fixed;
In the 2nd step, the assembly after step 1 installation is installed in the housing 02;
The 3rd goes on foot, and following insulated enclosure cover 07 is installed in the shaft shoulder place of collector plate 04;
The 4th step, housing 02 is carried out slot rolling, the slot rolling position is diagram distortion fold 02-2 correspondence position;
The 5th step, housing 02 is carried out the height shaping, the circular arc state when making slot rolling becomes the step state;
In the 6th step, insulated enclosure circle 06(is O type circle in install at the step place of the 5th one-step forming);
The 7th step is at the upper end of the collector plate 04 interference end cap 03 that is connected;
In the 8th step, install insulated enclosure cover 05 at the shaft shoulder place of end cap 03;
In the 9th step, seal processings at the opening part of housing 02, to obtain the 02-1 that turns edge that seals of needs.
The reason of part erection sequence must adopt three insulated enclosure members to combine and realize sealing and insulation in the therefore existing production technology; And relatively it seems with regard to production technology, the insulation and sealing structure assembly technology operation of energy storage device is longer in the prior art, production efficiency is low, and owing to the rigging error that three independent insulated enclosure members in use occur can be brought influence to the insulated enclosure performance of whole insulated enclosure body, so that in energy storage device, exist more potential uncertain influencing factor, the i.e. carelessness of the defective of any one part or assembling process all can cause the insulated enclosure of monomer to lose efficacy.
