Abstract
The utility model provides a cylindrical lithium-ion battery washer. Round holes are arranged around a washer body; a lug hole is arranged at the center of the washer body; and furthermore, the lug hole arranged at the center of the washer body is square. The cylindrical lithium-ion battery washer has the advantages of effectively avoiding the short circuit problem occurring as a positive lug is folded in a central hole, reducing the safety problem of a battery, reducing the friction between the washer and the positive lug by optimizing the dimension of the square hole, leading an upper washer to be quickly nested, and improving the production efficiency.
Description
[technical field]
The utility model relates to technical field of lithium ion, relates in particular to a kind of improvement of lithium ion battery pad.
[background technology]
At present, what the cylindrical lithium ion battery Upper gasket adopted is that the center pole earhole is the pad of borehole structure, in the course of processing, because center-hole diameter is bigger, anode ear is easy to bending and folds into centre bore, causes internal short-circuit, makes battery have very big potential safety hazard.
[utility model content]
The technical problems to be solved in the utility model is, cylindrical lithium ion battery pad anode ear at prior art is easy to bending and folds into centre bore, thereby the problem that causes internal short-circuit, the cylindrical lithium ion battery pad that a kind of center pole earhole is provided is square structure.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Be provided with circular hole around a kind of cylindrical lithium ion battery pad, described shim body, the shim body center is provided with the lug hole, and the lug hole at described shim body center is square.
Further preferred scheme is that described lug hole dimension is 8 * 2.0mm.
The beneficial effects of the utility model are:
1, can effectively avoid anode ear to fold into centre bore and cause problem of short-circuit, reduce cell safety hidden danger.
2, dimensionally-optimised by square hole, reduce the friction between Upper gasket and the anode ear, Upper gasket can be inserted in fast, improved production efficiency.
[description of drawings]
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model cylindrical lithium ion battery pad;
[embodiment]
See also Fig. 1, structural representation for the utility model cylindrical lithium ion battery pad, a kind of cylindrical lithium ion battery pad, be provided with circular hole 2 around the described shim body 1, shim body 1 center is provided with lug hole 3, the lug hole 3 at described shim body center is square, and lug, and 3 are of a size of 8 * 2.0mm.
During use, anode ear can directly be inserted in the square lug of pad hole 3, and lug and gummed paper is not produced extruding; In addition, also can avoid the lug bending to be pressed in the volume core centre bore, stop potential safety hazard.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
Claims (2)
1. a cylindrical lithium ion battery pad is provided with circular hole around the described shim body, and the shim body center is provided with the lug hole, it is characterized in that, the lug hole at described shim body center is square.
