Abstract
The utility model relates to a series connection device for single batteries. The device is made of conducting materials with good elasticity, and comprises a bottom surface and claw pieces, wherein the bottom surface is a round plane, the periphery of the bottom surface is provided with the plurality of claw pieces, and a certain angle is formed between the claw pieces and the bottom surface, thus leading the claw pieces to have certain axial elasticity; the shape of each claw piece is rectangular, cone-shaped, frustum-shaped, or arc-table-shaped; the outline of the periphery of the claw piece is adaptive to the outer outline of the ground surface of a battery; the bottom surface corresponds to the outline of the anode surface of the battery; and an annular table-board is arranged between the claw piece and the bottom surface. The series connection device for the single batteries is placed in a battery fixture block, applies axial pressure on the battery to lead the claw piece to be closely contacted with the cathode of the battery, and simultaneously the bottom surface is closely contacted with the anode of another battery, thus ensuring that the battery has enough contacting surface when in series connection, greatly reducing contact resistance, improving the whole performance of the battery pack, and simultaneously reducing the radial connecting size of the battery pack, improving the energy-volume ratio, and leading the assembly process of the battery pack to have simple operation, safety and reliability.
Description
Technical field
The utility model relates to a kind of cell jockey, particularly a kind of cell series connection apparatus.
Background technology
Battery pack is generally connected a plurality of cells and is realized the required voltage requirement, and whether the tandem compound connected mode of cell science, convenient, is directly connected to the packaging efficiency and the performance of battery strings joint group.The cell series system normally adopts the cell both positive and negative polarity directly to contact, and contact area is little and axial contact force is inconsistent.Disclose a kind of battery among the CN201270266Y and connected conducting strip, its conducting strip is the clamping battery radially, and this device need not apply axial force and can couple together battery plus-negative plate, and its defective is that calvus contacts with battery and is some contact or line contact, contact-making surface is less, and contact resistance is bigger.
The utility model content
For remedying above-mentioned deficiency, the utility model provides a kind of contact area big cell series connection apparatus.
The utility model cell series connection apparatus adopts the electric conducting material with favorable elasticity to make, and comprises bottom surface and calvus, the bottom surface is a circular flat, be provided with some calvus around it, have a certain degree between calvus and the bottom surface, make calvus have certain axial elasticity.
The utility model cell series connection apparatus, wherein: it is one of rectangle, taper, taper type, arc platform shaped that described calvus is shaped as.
The utility model cell series connection apparatus, wherein: peripheral profile of described calvus and battery ground outline adapt.
The utility model cell series connection apparatus, wherein: described bottom surface is corresponding with the anode facial contour.
The utility model cell series connection apparatus, wherein: be provided with ring-like table top between described calvus and the bottom surface.
The utility model cell series connection apparatus, be placed in the battery fixture block, during installation, by battery being applied axial compressive force calvus is closely contacted with the negative pole of a battery, the bottom surface closely contacts with the anodal of another battery simultaneously, thereby have enough big contact-making surface in the time of can guaranteeing the battery series connection, significantly reduce contact resistance, improve the overall performance of battery pack.Reduce the radially size for connection of battery pack simultaneously, improve the energy volume ratio.This brace device makes the battery pack assembling process simple to operate, safe and reliable.

Fig. 1 is the schematic diagram of the utility model cell series connection apparatus, and Fig. 2 is its vertical view, and Fig. 3 is its end view, and Fig. 4 is the stereogram after it flattens.
The utility model cell series connection apparatus, employing has the electric conducting material of favorable elasticity and makes, comprise bottom surface 12 and calvus 11, bottom surface 12 is a circular flat, be provided with some calvus 11 around it, the (see figure 3) that has a certain degree between calvus 11 and the bottom surface 12 makes calvus have certain axial elasticity.
It is one of rectangle, taper, taper type, arc platform shaped that calvus 11 is shaped as.
Calvus 11 peripheral profiles and the battery ground outline (see figure 2) that adapts.
Bottom surface and the corresponding (see figure 2) of anode facial contour.
Be provided with ring-like table top (see figure 3) between calvus and the bottom surface.
Its concrete use is seen Fig. 5.Cover one connects fixture block 3 between two batteries 2, and the bottom surface 12 of jockey 1 is facing to the positive pole of following battery 2, and calvus 11 is facing to the negative pole of a last batteries 2, applies certain pressure and promptly finishes connection between the chain batteries connecting battery.According to same method, can continue to connect the 3rd, the 4th battery.
