Summary of the invention
For above-mentioned prior art present situation, technical problem to be solved in the utility model is, provides a kind of lithium battery central tube, and it effectively can improve in electric core winding process the problem that is uneven, spiral that reels.Another technical problem to be solved in the utility model is, provides a kind of cylindrical lithium ion battery with this central tube.
In order to solve the problems of the technologies described above, a kind of lithium battery central tube provided by the utility model, comprises central tube main body, and described central tube main body is hollow structure, and described central tube main body is overall structure, and described central tube main material is PPS plastics.
Wherein in an embodiment, the centre bore of described central tube main body comprises middle first paragraph and the second segment be connected with first paragraph two ends and the 3rd section, and the cross section of described first paragraph is polygonized structure.
Wherein in an embodiment, the cross section of described first paragraph is hexagonal structure.
Wherein in an embodiment, the cross section of described second segment and described 3rd section is circular configuration.
Wherein in an embodiment, the diameter of described first paragraph is less than the diameter of described second segment and described 3rd section.
Wherein in an embodiment, described lithium battery central tube also comprises the heat-shrink tube be set in described central tube main body.
Wherein in an embodiment, described heat-shrink tube material is PE plastics.
A kind of cylindrical lithium ion battery provided by the utility model, comprise central tube and be wound in the battery core on described central tube, described central tube is above-mentioned central tube.
Compared with prior art, lithium battery central tube of the present utility model, central tube main body is overall structure, effectively can improve in electric core winding process the problem that is uneven, spiral that reels, improve electric core winding effect, improves battery performance; And, central tube main material is PPS plastics, PPS has excellent hot property, short-term can be resistance to 260 DEG C, and at 200 ~ 240 DEG C, excellent hot property can be had by Long-Time Service, the electrical property of PPS is very outstanding, compared with Other Engineering plastics, its dielectric constant and dielectric loss angle tangent value all lower, and change is little in larger frequency, temperature and temperature range.
The beneficial effect that the utility model additional technical feature has will be described in this specification embodiment part.
Accompanying drawing explanation
Fig. 1 is the vertical view of the lithium battery central tube in the utility model embodiment;
Fig. 2 is the A-A cutaway view of Fig. 1.
Description of reference numerals: 10, central tube main body; 11, the centre bore of central tube main body; 11a, first paragraph; 11b, second segment; 11c, the 3rd section; 20, heat-shrink tube.
Embodiment
And the utility model is described in detail below with reference to the accompanying drawings in conjunction with the embodiments.It should be noted that, when not conflicting, the feature in following embodiment and embodiment can combine mutually.
As shown in Figure 1, 2, the battery center pipe in one of them embodiment of the utility model comprises central tube main body 10, and described central tube main body 10 is hollow structure, and described central tube main body 10 is overall structure, and described central tube main body 10 material is PPS plastics.Because central tube main body is overall structure, effectively can improve in electric core winding process the problem that is uneven, spiral that reels, improve electric core winding effect, improve battery performance; And, central tube main material is PPS plastics, PPS has excellent hot property, short-term can be resistance to 260 DEG C, and at 200 ~ 240 DEG C, excellent hot property can be had by Long-Time Service, the electrical property of PPS is very outstanding, compared with Other Engineering plastics, its dielectric constant and dielectric loss angle tangent value all lower, and change is little in larger frequency, temperature and temperature range.
Preferably, second segment 11b and the 3rd section 11c that the centre bore 11 of described central tube main body 10 comprises middle first paragraph 11a and is connected with first paragraph 11a two ends, the cross section of described first paragraph 11a is polygonized structure.Further, the cross section of described first paragraph 11a is hexagonal structure.Because first paragraph 11a is non-circular, can prevent core from skidding, effectively can solve the problem of skidding.
Preferably, the cross section of described second segment 11b and described 3rd section of 11c is circular configuration.Like this, this central tube goes for circular core, and versatility is good.
Preferably, the diameter of described first paragraph 11a is less than the diameter of described second segment 11b and described 3rd section of 11c, to facilitate insertion core.
Preferably, battery center pipe also comprises the heat-shrink tube 20 be set in described central tube main body 10.Preferably, the material of described heat-shrink tube 20 is PE.During winding, heat-shrink tube 20 and barrier film are welded together.
In another embodiment of the utility model, provide a kind of cylindrical lithium ion battery, cylindrical lithium ion battery comprises central tube and is wound in the battery core on described central tube, and described central tube is the central tube in above-described embodiment.
