Technical Field

The invention relates to the field of battery structures, in particular to a military battery structure.

Background

In the manufacturing process of the miniature military battery structure, on one hand, the battery needs to be prevented from being interfered, and on the other hand, the battery needs to be noticed to be waterproof, but the existing battery cannot well solve the problems of water resistance and interference resistance.

In addition, traditional military battery need weld the utmost point ear on protection shield and the electric core in the manufacture process, but, the protection shield needs brush tin cream earlier, pastes the nickel piece among the prior art, just then can carry out spot welding with the utmost point ear of electric core, and whole technology is loaded down with trivial details, and the process is troublesome, and the cost is higher, and the military battery structure that produces like this is whole thick, is unfavorable for the ultra-thinness of military battery structure to be handled.

Disclosure of Invention

The invention provides a military battery structure, which solves the problems that the military battery in the prior art cannot prevent water and interference, and the welding process of a lug of a battery core and a protective plate is complicated, the working procedure is troublesome, the cost is high and the welding thickness is large.

In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides a military battery structure, includes electric core, protection shield, tin foil cover and the protective sheath of moulding plastics be equipped with anodal utmost point ear and negative pole utmost point ear on the electric core, anodal utmost point ear with negative pole utmost point ear all with the protection shield is connected be equipped with anodal lead-out wire and negative pole lead-out wire on the protection shield, tin foil cover parcel electric core with the protection shield, the protective sheath of moulding plastics sets up tin foil cover periphery, the protective sheath of moulding plastics is through the integrated into one piece that moulds plastics, anodal lead-out wire with the negative pole lead-out wire passes tin foil cover with the protective sheath of moulding plastics exposes externally.

Preferably, the protection shield contains PCB plate layer, copper plating layer and welding layer in proper order, the welding layer is nickel plating layer or heavy nickel layer, anodal utmost point ear with negative pole utmost point ear all with welding layer fixed connection.

Preferably, the positive electrode lug and the negative electrode lug are fixedly connected with the welding layer in a spot welding mode.

Preferably, a chip for controlling the protection plate is arranged on the protection plate.

Preferably, the chip 7 is disposed on one face of the PCB board layer.

Preferably, the overall shapes of the protection plate and the battery cell are both rectangular.

Preferably, the edges of the protection plate and the battery cell are arranged in parallel.

Preferably, the distance between the protective plate and the battery cell is 0.1mm-5.0 mm.

The invention has the following beneficial effects: compared with the existing design, the invention solves the problem of interference by wrapping the electric core and the protective plate by the tin foil cover, and solves the problem of water resistance by the injection protective sleeve formed by integral injection molding. Meanwhile, the structure of the protection plate is changed, the protection plate is changed into a three-layer structure, namely a PCB plate layer, a copper plating layer and a welding layer, the welding layer is a nickel plating layer or a nickel deposition layer, and the positive pole lug and the negative pole lug are fixedly connected with the welding layer in a spot welding mode, so that the original layer number of the protection plate is reduced, the protection plate is thinner, and the process is simpler and the production cost is greatly reduced because the number of brushing tin paste and sticking nickel sheets is reduced compared with the traditional design.
