The utility model has carried out structural improvement to traditional alkaline secondary cell sealing means, has effectively solved the sealing problem of alkaline secondary cell, and alkali lye can't be climbed out of, thereby overcomes " climbing alkali " phenomenon of battery, improves the battery rate of finished products.
Description of drawings
Fig. 1 is an alkaline secondary cell profile of the present utility model;
Fig. 2 is an alkaline secondary cell combination cover cap assembly profile of the present utility model.
Embodiment
In conjunction with the accompanying drawings the utility model is described in detail as follows:
Make long 31mm, wide 15mm, thick 5mm, wall thickness 0.5mm and open-topped square stainless steel metal battery case 8 (all not illustrating among Fig. 1), reach bottom 3 some covers of long 15mm, wide 5mm, wall thickness 0.5mm; As shown in Figure 2, on bottom 3, form the following concave station of long 14mm, wide 4mm by mechanical stamping, the width of periphery seam is 0.5mm, the middle part of bottom concave station is provided with the depression that contains perforate, the about 1.0mm of cup depth, corresponding with sealing ring thickness, the upper surface of around opening is provided with projection and the lower surface is provided with fovea superior; Make as shown in Figure 2 last cap 1, explosion-proof ball 2, rivet 4, sealing ring 5, insulation cushion 6, lug sheet 7.
As shown in Figure 1, bottom 3 is cores of combination plate assembly, and the upper surface by around opening is provided with projection and is placed on it limit sealing ring 5 edges and closes.Insulation cushion 6 major functions are that bottom 3 and lug sheet 7 are kept apart, and rivet 4, lug sheet 7 link to each other with anode, and bottom 3 links to each other with battery case 8, is the negative pole of battery.Rivet 4 is hollow, passes through the perforate of sealing ring 5, bottom 3, insulation cushion 6, lug sheet 7 successively and makes it to form a close body through riveting, and last cap 1 compression explosion-proof ball, 2 sealing rivet perforates are also fixing with the rivet head welding.
Adhesive coating before assembling after the riveted joint pressurization, more can improve the ability that prevents to climb alkali.Preferred above-mentioned bottom 3, sealing ring 5, lug sheet 7 geometries more help to increase the area of riveted joint faying face, and anti-creep alkali is played a crucial role.
The combination plate assembly shortens at the vertical direction pressurized, three-dimensional pressurized makes faying face chimeric good, add adhesive and stop up the capillary channel effect, form good sealing, the peripheral fixing structure of bottom 3, concave station location combination plate embed battery case, and the joint line of battery case and combination plate is in the battery side, joint line is by laser welded seal, in the time of can guaranteeing to carry out laser welding sealing, heat does not destroy established sealing, and alkali lye can't seepage.
