Abstract
The utility model discloses a kind of polar ear structure of cylindrical lithium battery, the lower end of electrode (1) is connected with N number of lug (2), N be greater than 3 integer; Form one between 2 often adjacent lugs for holding the groove of drainage piece (4) upper end, described groove is N-1; Drainage piece is N-1, and the upper end correspondence of N-1 drainage piece is inserted in a described N-1 groove, the upper end of drainage piece and lug is equipped with for the through hole through rivet (3), is fixedly connected with between the upper end of drainage piece and lug by described rivet; The lower end correspondence of N-1 drainage piece is connected with N-1 battery core (5).N is the integer between 5-6.The polar ear structure of this cylindrical lithium battery has the feature of novel structure, is connected firmly, good stability.
Description
Technical field
The utility model relates to a kind of polar ear structure of cylindrical lithium battery.
Background technology
Lug is used for conduction electrode and battery core, therefore, if connect firm not, easily cause larger contact resistance, cause battery-heating serious, dangerous increase, in addition, connect the loose contact also easily causing battery core and electrode built on the sand, therefore, be necessary the polar ear structure designing a kind of novel cylindrical lithium battery.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of polar ear structure of cylindrical lithium battery, and the polar ear structure of this cylindrical lithium battery has novel structure, is connected firmly, the advantage of good stability.
The technical solution of utility model is as follows:
A polar ear structure for cylindrical lithium battery, the lower end of electrode (1) is connected with N number of lug (2), N be greater than 3 integer; Form one between 2 often adjacent lugs for holding the groove of drainage piece (4) upper end, described groove is N-1;
Drainage piece is N-1, and the upper end correspondence of N-1 drainage piece is inserted in a described N-1 groove, the upper end of drainage piece and lug is equipped with for the through hole through rivet (3), is fixedly connected with between the upper end of drainage piece and lug by described rivet;
The lower end correspondence of N-1 drainage piece is connected with N-1 battery core (5).
N is the integer between 4 ~ 6.
N is 5.
Beneficial effect:
The polar ear structure of cylindrical lithium battery of the present utility model, adopt the multi-disc lug of fence type and rivet to realize the connection of electrode and battery core, drainage piece is not easy to get loose, therefore, the polar ear structure of this cylindrical lithium battery has novel structure, is connected firmly, the advantages such as good stability.
Accompanying drawing explanation
Fig. 1 is the general structure schematic diagram of the polar ear structure of cylindrical lithium battery of the present utility model.
Label declaration: 1-electrode, 2-lug, 3-rivet, 4-drainage piece, 5-battery core.
