Abstract

The utility model discloses a novel utmost point ear structure, main content is: include that aluminium strip, first ploe ear are glued, aluminium changes nickel, first nickel strap, second nickel strap and second ploe ear and glues, aluminium commentaries on classics nickel fixed mounting just is close to the right -hand member face of aluminium strip on the top surface of aluminium strip, the right -hand member face fixed connection of first nickel strap left end face and aluminium commentaries on classics nickel is in the same place, and the aluminium strip passes through gluey the fixing of first ploe ear with aluminium commentaries on classics nickel is in the same place, and the first ploe ear is glued and the gluey insulating cement that is of second ploe ear, the cladding has the second ploe ear to glue on the second nickel strap, the utility model discloses a structure that the regulating pole ear was glued, on the strap cladding one deck insulating cement, completely cut off the strap of utmost point ear, avoided the risk hidden danger such as explosion on fire that strap contact pole piece results in.

Description

A kind of polar ear structure

Technical field

This utility model relates to lithium ion cell polar ear technical field of structures, specifically, particularly to a kind of polar ear structure。

Background technology

Along with lithium ion battery using in a large number in electric motor car, the energy density of battery requires significantly high, the safety of battery also requires that higher, especially battery capacity is more than more than 8AH, when there is battery short circuit if as improper use, inside battery humidity sharply raises, and can cause battery bulge, aluminum plastic film is burst, and the harm such as batteries caught fire are even packed up in electrolyte leakage。If can cut off the electricity supply in time when short circuit occurs, battery would not break in bulge, and secondary harm would not occur。Safety for protection battery generally can install protection circuit board additional outside battery core。When battery be short-circuited or overcharge cause battery-heating time, heat reaches protection circuit arrangement from battery main body, the outer protection circuit operation when the heat being transmitted through reaches uniform temperature, cuts off the electricity supply thus playing a protective role。Connecting damage open circuit when outside batteries protection component runs into element or conduct heat smooth electronic component sensing not in time, battery core loses circuit protection and increases the potential safety hazard of battery。

Utility model content

Technical problem to be solved in the utility model is in that for above-mentioned deficiency of the prior art, it is provided that a kind of polar ear structure, its simple in construction and this structure make the IGP of lithium ion battery get a promotion。

This utility model solves its technical problem and be the technical scheme is that a kind of polar ear structure, including aluminium strip, the first tab, aluminium-to-nickel, the first nickel strap, the second nickel strap and the second tab；Described aluminium-to-nickel is fixedly mounted on the end face of aluminium strip and near the right side of aluminium strip, the right side of described first nickel strap left side and aluminium-to-nickel is fixed together, described aluminium strip and aluminium-to-nickel are fixed together by the first tab, described first tab and the second tab are insulating cement, and described second nickel strap is coated with the second tab。

As preferably, described first tab is double layers table hierarchic structure, and lower floor is wider than upper strata。

As preferably, described second tab is double layers table hierarchic structure, and lower floor is wider than upper strata。

This utility model, by the structural adjustment to tab and lug, prevents the metal tape of lug from directly contacting core head surface when bending lug, it is prevented that the generation of internal short-circuit, as shown in Figure 3 and Figure 4。

This utility model compared with prior art has the advantage that the structure by adjusting tab, has been coated with one layer of insulating cement, has completely cut off the metal tape of lug on metal tape, it is to avoid the blast equivalent risk hidden danger on fire that metal tape contact pole piece causes。

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model detailed description of the invention is described:

It should be noted that, the structure of signal, ratio, size etc. in this specification institute accompanying drawing, all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop on the disclosed technology contents of this utility model and obtain in the scope that can contain。

Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre " and " one " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model。

As shown in accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4, it illustrates a kind of detailed description of the invention of the present utility model, as it can be seen, a kind of polar ear structure, including aluminium strip the 1, first tab 2, aluminium-to-nickel the 3, first nickel strap the 4, second nickel strap 5 and the second tab 6；Described aluminium-to-nickel 3 is fixedly mounted on the end face of aluminium strip 1 and near the right side of aluminium strip 1, the right side of described first nickel strap 4 left side and aluminium-to-nickel 3 is fixed together, described aluminium strip 1 and aluminium-to-nickel 3 are fixed together by the first tab 2, described first tab 2 and the second tab 6 are insulating cement, and described second nickel strap 5 is coated with the second tab 6。

Preferably, described first tab 2 is double layers table hierarchic structure, and lower floor is wider than upper strata。
