Abstract
The utility model discloses a battery serial connection device. Two cylindrical batteries are connected in series with each other by the battery serial connection device. In the specific embodiment, the battery serial connection device comprises at least two elastic clamp pieces, and as least one of the upper end faces of the elastic clamp pieces is formed by bending inwards; the elastic clamp pieces are characterized in that a battery cathode is inserted into the elastic clamp pieces, and elastic pieces of which the upper end faces are formed by bending inwards radially clamp a battery shell; the bottom surface of the battery serial connection and clamping device is provided with the elastic pieces contacting the cathode, and the middle of the reverse side of the bottom surface is provided with a boss stretching downwards; an I-shaped diffluent trough is formed in the boss; bumps which are spot-welded with an anode cap of the other battery are uniformly distributed on two sides of the diffluent trough; and therefore, the batteries are serially connected with each other. The battery serial connection device is made of high-elasticity electric conduction metal.
Description
Technical field:
The utility model relates to the battery series connection apparatus, is specially adapted to use when cylindrical battery is connected in series.
Background technology:
Battery pack generally is a plurality of cells to be connected realize 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.General cylindrical battery positive pole is drawn by block; The whole negative pole that belongs to of battery case; There is very big pressure release cavity the block below; Therefore can bear very big welding current during anode spot welding, and negative pole is a shell because the hidden danger of the electric in-core of damage portion is just arranged when weld apart from internal cell pole piece very near point.A kind of battery connecting apparatus is disclosed among the CN201270266Y; 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.
Summary of the invention:
The task of the utility model is to propose a kind of the assurance to have enough big contact-making surface when battery is connected, and significantly reduces contact resistance, improves the battery series connection apparatus of the overall performance of battery pack.
The task of the utility model is to accomplish like this; It is to rely on the battery series connection apparatus to accomplish that two pitch circle cylindricality battery strings join together; The elastic clip of concrete enforcement more than at least 2 formed, and has at least a place that inside brake forming is arranged in the upper surface of described elastic clip, the feature structure of elastic clip described above; Purpose is that GND inserts in the elastic clip, radially clamps battery case by the moulding that curves inwardly on the said flexure strip end face;
The bottom surface of said battery series connection gripping mechanism is designed with the flexure strip that touches mutually with negative pole; Boss to stretched is arranged in the middle of the back side of bottom surface; It on the boss " worker " font splitter box; Being evenly distributed with and the salient point of the anodal block of another batteries spot welding of its both sides, thus being connected in series of battery accomplished.
The utlity model has following effect: this jockey is processed by the high resiliency conducting metal; Jockey is provided with anode connection terminal and negative pole link; Adopt electric resistance welding to be connected between anode connection terminal and the anode block; Adopt the close physical contact to be connected between negative pole link and the GND end, can avoid GND is implemented to have the spot weld operation of potential safety hazard, can guarantee that battery has enough big contact-making surface when connecting simultaneously again; Significantly reduce contact resistance, improve the overall performance of battery pack.

Illustrate: 1, flexure strip, 2, elastic clip, 3, the bottom surface, 4, the slit, 5, " worker " font splitter box, 6, salient point, 7, boss, 8, the boss panel, 9, the GND end, 10, the anode block.
Embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing; The technical scheme that the utility model will solve is will be connected in series cylindrical battery to be snapped together; Said battery series connection gripping mechanism is made up of a plurality of elastic clips 2, and (seeing shown in Figure 1) has slit 4 between the elastic clip; The shape of the upper surface of said elastic clip is the shaping that curves inwardly; On the bottom surface of said battery series connection gripping mechanism, the flexure strip 1 that touches mutually with GND end 9 is arranged, the boss 7 of stretched is arranged in the middle of the back side of bottom surface 3, the salient point 6 with 10 spot welding of the anodal block of another batteries is arranged on the panel 8 of said boss; Said salient point is to be evenly distributed on said boss panel " worker " font groove both sides; The shape of said flexure strip 1 can be the shell fragment of warpage upwards, also can be spring leaf, and the high resiliency conducting metal that said series connection gripping mechanism is selected for use is meant that copper, copper alloy and aluminium alloy process.
The utility model is not limited to above-mentioned execution mode, no matter in its shape or do any variation above the structure, every flexure strip that utilizes can radially clamp battery case; The protection range that all belongs to the utility model in addition, has the curve inwardly shell fragment of moulding of a place at least on the end face with flexure strip; The end face that changes flexure strip into has an elasticity card; After the edge distortion battery case being clamped, all is a kind of distortion of the utility model, all should think and drop in the utility model protection range.
