The invention has a simple and compact structure, is convenient for processing, and has low manufacturing cost; the holding power between batteries is increased, and the installation efficiency is high; the contact surface of the connection between electrode ends of the battery is increased, and the contact internal resistance is reduced; with the invention, the disassembly of the battery is simple, and the battery is convenient for maintenance.

Description

Jockey between a kind of assembled battery
Technical field
The present invention relates to the jockey between a kind of assembled battery.
Background technology
At present, cell is that bottom adopts a columned metal shell as negative pole mostly, and top adopts a metal electrode plate seals as positive pole.In the process that multiple cells are connected, a certain electrode of each cell is connected to by spot welding on the opposite electrode of another one cell, then, at storage battery overcoat one deck macromolecule shrink film of series connection, forms battery module.
In pinpoint welding procedure, because the electric current of crossing from electrode stream is larger, if use very thick connector, operate very difficult, waste time and energy; If adopt thinner or banded connector, easily breakdown while welding, and connector electroplating equipment wielding machine intensity is lower, and the connection power between battery is not strong yet, easily produces and opens circuit, and useful life is short, and scrappage is higher; In addition, while adopting spot welding mode, process velocity is slower, inefficiency; And when multiple cells being fastened as a whole by macromolecule shrink film, support force is inadequate, easily causes the phenomenons such as battery module distortion.
Summary of the invention
The above-mentioned defect existing in order to overcome prior art, the invention provides one and can effectively extend battery module useful life, handling ease, the jockey between the larger assembled battery of support force.
Technical scheme of the present invention is: it comprises insulating part and nonisulated, be located at insulating part inner side for described nonisulated, insulating part middle part madial wall is corresponding with nonisulated lateral wall shape, nonisulated upper surface shape and battery cathode bottom shape are similar, nonisulated bottom is provided with the groove suitable with the projection at anode top, insulating part upper inner wall and battery cathode end housing closely cooperate, and insulating part lower inside wall and anode end housing closely cooperate.
Described insulating part can adopt plastic cement, pottery, rubber or other insulating composite material manufacture; Nonisulated can adopt metal, alloy or other electric conducting material manufacture.
Between anode end housing and anode top, being provided with anode insulation cushion, is the parts of battery itself, for isolated anode end housing and anode top.
Jockey between assembled battery of the present invention is combined by insulating part and nonisulated, metal solder joint can be set according to the actual requirements or connect battery electrode by complete contact-making surface; Insulating part plays the effect of isolated anode end housing, prevents that nonisulated contacts with anode end housing, causes opening circuit; Under insulating part and nonisulated 's effect, the negative pole end of a cell and the positive terminal of next cell are surrounded completely, strengthen by surrounding the support force that the mode of electrode tip makes battery completely; Contact with the complete of anode top by the bottom of nonisulated, and the upper surface of nonisulated is realized contact area maximization with complete contact of battery cathode bottom, the maximization area of realizing the negative pole end of a upper cell and the positive terminal of next cell is closely connected, and contact internal resistance is little; In the time that wherein a certain cell goes wrong, only it need be taken out from jockey, change new cell.
The present invention is simple in structure, compact, easy to process, low cost of manufacture; Support force between battery increases, and installation effectiveness is high; Use the present invention, battery dismounting is simple, is convenient to safeguard.
Brief description of the drawings
Fig. 1 is one embodiment of the invention structural representation.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to Fig. 1, the present embodiment comprises insulating part 1 and nonisulated 2, be located at insulating part 1 inner side for described nonisulated 2, insulating part 1 middle part madial wall is corresponding with nonisulated 2 lateral wall shapes, nonisulated 2 upper surface shape and battery cathode bottom 7 shapes are similar, nonisulated 2 bottoms are provided with the groove suitable with the projection 8 at anode top 5, and insulating part 1 upper inner wall and battery cathode end housing 4 closely cooperate, and insulating part 1 lower inside wall and anode end housing 3 closely cooperate.
Described insulating part 1 adopts plastic cement or pottery to manufacture, but also other insulating material is manufactured.Adopt metal or alloy manufacture for nonisulated 2, also can manufacture with other electric conducting material.
Between anode end housing 3 and anode top 5, have anode insulation cushion 6, anodal insulation cushion 6 is the parts of battery itself, for isolated anode end housing 3 and anode top 5.
Insulating part 1 plays the effect of isolated anode end housing 3, prevents that nonisulated 2 contacts with anode end housing 3, causes opening circuit.Contact with the complete of anode top 5 by the bottom of nonisulated 2, and complete contact of the upper surface of nonisulated 2 and battery cathode bottom 7, contact area is maximized, the area of realizing the negative pole end of a upper cell and the positive terminal of next cell maximizes close contact, thereby is conducive to reduce to contact internal resistance.

Claims (2)

1. the jockey between an assembled battery, it is characterized in that, comprise insulating part and nonisulated, be located at insulating part inner side for described nonisulated, insulating part middle part madial wall is corresponding with nonisulated lateral wall shape, nonisulated upper surface shape and battery cathode bottom shape are similar, nonisulated bottom is provided with the groove suitable with the projection at anode top, insulating part upper inner wall and battery cathode end housing closely cooperate, and insulating part lower inside wall and anode end housing closely cooperate;
