For achieving the above object, the technical solution adopted in the utility model is:
Electrode tab connection structure in a kind of lithium battery group described in the utility model, including lithium battery group body and connection body, described lithium battery group body includes several battery bodies, described battery body is provided with two pole piece ears, described connection body includes a connecting piece and second and connects sheet, described pole piece in ear is provided with for connecting first, two cavitys connecting sheet, this cavity one end is opening-like, described a connecting piece end surface is fixedly installed several cushions, described a connecting piece one end and coupled cushion all stretch in the anode pole piece ear cavity of a battery body, described second connects sheet end surface is fixedly installed several cushions, described second connection sheet one end and coupled cushion all stretch in the cathode pole piece ear cavity of another battery body, described a connecting piece other end surface configuration has several projections, described second connects the through hole that sheet other end surface configuration has several and projection to match mutually, projection nesting is in through-holes.
Further, described a connecting piece end surface is positioned at the underface of connected cushion, and described second connects sheet end surface is positioned at the surface of connected cushion.
Further, described cushion is spring.
Further, the quantity of described cushion is two.
Further, described projection and through hole are fixedly connected by welding.
Further, all rounded shape of the cross section of described projection and through hole.
After adopting said structure, this utility model has the beneficial effect that when using this utility model, first a connecting piece one end and coupled cushion are all stretched in the anode pole piece ear cavity of a battery body, then second connection sheet one end and coupled cushion are all stretched in the cathode pole piece ear cavity of another battery body; Finally the projection of a connecting piece is enclosed within the through hole of the second connection sheet; Both can achieve a fixed connection, production efficiency can be improved again, reduce production cost. This utility model has simple in construction, arranges rationally, the advantages such as cost of manufacture is low.

Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is illustrated.
As shown in Figure 1 to Figure 2, electrode tab connection structure in a kind of lithium battery group described in the utility model, including lithium battery group body and connection body, described lithium battery group body includes several battery bodies 1, described battery body 1 is provided with two pole piece ear 1-1, and the anode pole piece ear 1-1 of a battery body 1 is by connecting the cathode pole piece ear 1-1 of body and another battery body 1.
Described connection body includes a connecting piece 21 and second and connects sheet 22, it is provided with for connecting first in described pole piece ear 1-1, two connect sheet 21, the cavity of 22, this cavity one end is opening-like, described a connecting piece 21 end surface is fixedly installed several cushions 3, described a connecting piece 21 one end and coupled cushion 3 all stretch in the anode pole piece ear 1-1 cavity of a battery body 1, described second connects sheet 22 end surface is fixedly installed several cushions 3, described second connection sheet 22 one end and coupled cushion 3 all stretch in the cathode pole piece ear 1-1 cavity of another battery body 1, described a connecting piece 21 other end surface configuration has several projections 21-1, described second connects sheet 22 other end surface configuration several through holes matched with projection 21-1 phase, projection 21-1 nesting is in through-holes.
Further, described a connecting piece 21 end surface is positioned at the underface of connected cushion 3, and described second connects sheet 22 end surface is positioned at the surface of connected cushion 3; So arrange to be primarily to and step down, also allow for projection 21-1 simultaneously and be inserted in through hole.
