The utility model provides a cylinder battery negative pole post and negative pole keysets subassembly and cylinder battery is because negative pole keysets and negative pole post structure as an organic whole can reduce welding processes one, reduce cost, furthermore, the front of negative pole keysets is the plane, has cancelled the guiding gutter, and heat conduction and electrically conductive area are big, and reduces manufacturing procedure one, reduces the burr, improves the inside cleanliness of battery.
Description
Technical field
The utility model relates to cell art, particularly relates to a kind of cylindrical battery negative terminal and negative pole keyset assembly and cylindrical battery.
Background technology
Existing cylindrical lithium ion battery generally includes battery core, positive pole keyset, negative pole keyset, Positive Poles and negative pole pole, and negative pole pole and negative pole keyset are two independent parts, and during assembling, negative pole pole and negative pole keyset adopt together with laser welding; And negative pole keyset is provided with refluence groove on the surface of battery core side, heat transfer and conductive area reduce, and jagged, affect inside battery cleannes.
Summary of the invention
For above-mentioned prior art present situation, the utility model provides a kind of cylindrical battery negative terminal and negative pole keyset assembly and cylindrical battery, reduces operation, reduces costs, and reduces burr, improves inside battery cleannes.
In order to solve the problems of the technologies described above, a kind of cylindrical battery negative terminal provided by the utility model and negative pole keyset assembly, comprise negative terminal and negative pole keyset, described negative pole keyset has in the face of the front of battery core and the back side back to battery core, the middle part at the back side of described negative pole keyset is provided with round boss, and described boss is connected with one end of described negative terminal; The front of described negative pole keyset is plane, and described negative pole keyset and described negative terminal are structure as a whole.
Wherein in an embodiment, described boss comprises from described front to the first boss, the second boss and the 3rd boss that described negative terminal connects successively, and the external diameter of described first boss, described second boss and described 3rd boss reduces successively.
Wherein in an embodiment, the height of described first boss is 2.0 ~ 3.0mm.
Wherein in an embodiment, the height of described 3rd boss is 1.5 ~ 2.0mm.
A kind of cylindrical battery provided by the utility model, comprises above-mentioned assembly.
Compared with prior art, the cylindrical battery negative terminal that the utility model provides and negative pole keyset assembly and cylindrical battery, because negative pole keyset and negative terminal are structure as a whole, can reduce by one welding sequence, reduce costs; And the front of described negative pole keyset is plane, eliminates guiding gutter, heat conduction and conductive area greatly, and reduce by one manufacturing procedure, reduce burr, improve inside battery cleannes.
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 sectional structure schematic diagram of cylindrical battery negative terminal in the utility model embodiment and negative pole keyset assembly;
Fig. 2 is the vertical view of cylindrical battery negative terminal in the utility model embodiment and negative pole keyset assembly;
Fig. 3 is the upward view of cylindrical battery negative terminal in the utility model embodiment and negative pole keyset assembly.
Description of reference numerals: 10, negative terminal; 20, negative pole keyset; 21, front; 22, the back side; 23, boss; 23a, the first boss; 23b, the second boss; 23c, the 3rd boss.
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.
See Fig. 1-3, cylindrical battery negative terminal in one of them embodiment of the utility model and negative pole keyset assembly comprise negative terminal 10 and negative pole keyset 20, described negative pole keyset 20 has in the face of the front 21 of battery core and the back side 22 back to battery core, the front 21 of described negative pole keyset 20 is plane, the middle part at the back side 22 of described negative pole keyset 20 is provided with round boss 23, described boss 23 is connected with one end of described negative terminal 10, and described negative pole keyset 20 is structure as a whole with described negative terminal 10.Because negative pole keyset 20 and negative terminal 10 are structure as a whole, can reduce by one welding sequence, reduce costs; And the front 21 of described negative pole keyset 20 is plane, eliminates guiding gutter, heat conduction and conductive area greatly, and reduce by one manufacturing procedure, reduce burr, improve inside battery cleannes.
More preferably, described boss 23 comprises from described front 21 to the first boss 23a, the second boss 23b and the 3rd boss 23c that described negative terminal 10 connects successively, and the external diameter of described first boss 23a, described second boss 23b and described 3rd boss 23c reduces successively.Compared with existing negative pole keyset, the boss 23 of the utility model embodiment adds the first boss 23a, thus increases inside battery space, can reduce the fluid injection time.Further preferably, the height H 1 of described first boss 23a is 2.0 ~ 3.0mm.
More preferably, the height H 2 of described 3rd boss 23c is 1.5 ~ 2.0mm, compares existing negative pole keyset, and the height of the 3rd boss 23c adds 0.5-1mm, so in the end during one welded seal, and the situation that when can effectively prevent battery core shorter, boss sink.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
