Abstract
The utility model relates to a kind of lithium ion power battery pole ear, comprises metal conductor strip, lug blob of viscose, is provided with hole in the edge of the longer one end of described metal conductor strip; Described hole is U-shaped hole, and its both sides are parallel, and top is circular arc; 1 can be arranged or multiple U-shaped hole fixes battery pole ear according to the width of metal conductor strip.Battery core factory by battery in groups time can not use laser welding, directly through U-shaped hole and compressing tablet, lug is locked together with screw, so namely saves the investment of large laser welding equipment, handled easily again, successful.Avoid the generation of rosin joint, reduce production cost, improve production efficiency.
Description
Technical field
The utility model relates to field of lithium ion battery material, is specially a kind of lithium ion power battery pole ear.
Background technology
The advantages such as it is high that current lithium-ion-power cell has voltage, and energy density is high, and cycle-index is many, are widely used in electric automobile, electronic bus, the electrical equipment aspects such as electric bicycle.In the production of batteries of electric automobile, battery combination connection is also a ring of most critical, what current application was maximum is use laser the mode of the positive pole ear of battery core and negative lug series connection or parallel connection to be welded together, but the maximum shortcoming of laser welding is the sensitiveness of its focusing, when the distance of laser head to solder joint occurs slightly to change, intensity and the effect of welding will change thereupon, battery pack weld strength can be caused so inconsistent, the even possibility of rosin joint, potential safety hazard is brought to battery, lug conductor in addition due to electrokinetic cell use is not only wide but also thick, so need very powerful laser welder guarantee weld strength to meet the demands, this fund of increasing input undoubtedly.
Utility model content
For the deficiencies in the prior art, provide a kind of easy to operate, the lithium ion power battery pole ear of dependable performance, ensure that the Contact of cell polar ear is tight, without rosin joint, do not need to use large laser welding equipment, for cell production companies reduces production cost.
The utility model is for solving the problems of the technologies described above by the following technical solutions:
A kind of lithium ion power battery pole ear, comprises metal conductor strip, lug blob of viscose, is provided with hole in the edge of the longer one end of described metal conductor strip.
Described hole is U-shaped hole, and its both sides are parallel, and top is circular arc.
The width of metal conductor strip, at 25mm to 40mm, described U-shaped Kong Weiyi, is arranged on the centre position of the longer one end of metal conductor strip; The width of metal conductor strip is greater than 40mm, and described U-shaped hole is two, is arranged on the centre position of the longer one end of metal conductor strip.
The spacing at the described edge in U-shaped hole and the edge of metal conductor strip is greater than 10mm.
The angle of this lug metal conductor strip is rounding processing.
The utility model adopts above technical scheme compared with prior art, has following technique effect:
Battery core factory by conductor battery in groups time can not use laser welding, directly through U-shaped hole and compressing tablet, lug is locked together with screw, so namely saves the investment of large laser welding equipment, handled easily again, successful.Avoid the generation of rosin joint, reduce production cost, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the structural representation of a kind of embodiment of the utility model;
The schematic cross-section of the lithium ion power electrokinetic cell extreme ear structure that Fig. 3 provides for the utility model;
Wherein, 1-U shape hole, 2-lug blob of viscose, 3-metallic conductor band.
Embodiment
The utility model provides a kind of lithium ion power electrokinetic cell lug, and for making the purpose of this utility model, technical scheme and effect clearly, clearly, and further describe the utility model with reference to accompanying drawing examples.Should be appreciated that concrete enforcement described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Be described in detail below in conjunction with the technical scheme of accompanying drawing to utility model:
In the hole that the 7mm that the distance stamping-out two of longer one end (being namely exposed to the part of battery core) of both positive and negative polarity lug distance tab outward flange 4mm is parallel is wide, the top in hole is circular arc, prolongs piercing edge break to prevent metallic conductor.The outer ledge distance conductor edge of two cylindrical voids is minimum is 10mm, four angles of lug are rounding processing, the aluminum plastic film avoiding lug to pierce through battery core causes battery core bad, and this scheme is greater than for conductor metal width the electrokinetic cell lug that 25mm thickness is greater than 0.15mm.
Embodiment 1
The utility model provides a kind of lithium ion power electrokinetic cell extreme ear structure as shown in Figure 1, and concrete structure is:
Comprise metal conductor strip, lug blob of viscose, be provided with U-shaped hole in the edge of the longer one end of described metal conductor strip, its both sides are parallel, and top is circular arc.The angle of this lug metal conductor strip is rounding processing.In the present embodiment, the width of metal conductor strip, at 25mm to 40mm, above-mentioned U-shaped Kong Weiyi, is arranged on the centre position of the longer one end of metal conductor strip; The spacing at the described edge in U-shaped hole and the edge of metal conductor strip is greater than 10mm.
Embodiment 2
The utility model provides a kind of lithium ion power electrokinetic cell extreme ear structure as shown in Figure 2, and concrete structure is:
Comprise metal conductor strip, lug blob of viscose, be provided with U-shaped hole in the edge of the longer one end of described metal conductor strip, its both sides are parallel, and top is circular arc.The angle of this lug metal conductor strip is rounding processing.In the present embodiment, the width of metal conductor strip is greater than 40mm, and described U-shaped hole is two, is arranged on the centre position of the longer one end of metal conductor strip; The spacing at the above-mentioned edge in U-shaped hole and the edge of metal conductor strip is greater than 10mm.
The lithium ion power battery pole ear that the utility model provides, the effect in U-shaped hole is for placing screws, by using screw by the positive pole of battery pole ear, negative pole series connection or being together in parallel.So namely, save the investment of large laser welding equipment, handled easily again, successful.Avoid the generation of rosin joint, reduce production cost, improve production efficiency.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, and all these change or replace the protection range that all should belong to the claim appended by the utility model.
