Abstract
The utility model relates to a kind of aluminium-to-nickel folding tabs, several aluminium strips and nickel strap including alternate setting, the end of adjacent aluminium strip and nickel strap mutually overlaps and is welded together to form weld part, the aluminium strip is coated with gel close to one end of the nickel strap, and the gel extends towards the nickel strap and covered section weld part.The utility model has good folding resistance.
Description
Technical field
The utility model relates to tab field, especially a kind of aluminium-to-nickel folding tab.
Background technique
The material of the positive pole ear of soft-packaged polymer lithium ion battery is usually fine aluminium.Battery is needed when processing assembling
The positive and negative anodes of battery are connect with other electron component by welding, however the positive pole ear made of fine aluminium cannot be straight
Tap into row scolding tin.Existing technique is usually exit one section of nickel strap of welding in cell positive pole ear, then passes through nickel strap and carry out
Soldering, this technique are referred to as the positive pole ear aluminium-to-nickel technique of soft-packaged polymer lithium ion battery.And the weldering of aluminium strip and nickel strap
Aluminium strip beside the place of connecing is left white not folding, is easily damaged.
Utility model content
Based on this, it is necessary to provide a kind of aluminium-to-nickel folding tab, several aluminium strips and nickel strap including alternate setting are adjacent
Aluminium strip and the end of nickel strap mutually overlap and be welded together to form weld part, the aluminium strip is wrapped close to one end of the nickel strap
It is covered with gel, the gel extends towards the nickel strap and covered section weld part.
The aluminium strip of tab is in contact close to the part of weld part with more hard weld part, therefore its not folding, is easy
Damage, thus the utility model the intersection of weld part and aluminium strip be arranged gel, gel simultaneously covered section aluminium strip and
Part weld part avoids the intersection overflexing of aluminium strip and weld part, so that tab more folding, and the structure can be saved effectively
The about production time improves production efficiency.
Preferably, the two sides of the gel towards the tab extend to form glue shoulder, and the width of the glue shoulder is 0.7-
3.0mm。
Glue shoulder is used to increase the width of gel, the bonding strength of the gel to increase tab both side surface, simultaneously
It can increase the folding resistance of gel.
Preferably, the gel is one of yellow glue, black glue or white glue.
Further, the length of the gel is 4.0-8.0mm.
Preferably, the length of the weld part is 2.5-3.5mm.
Further, the gel at least covers the length of weld part 0.3mm.
The principles of the present invention, effect are further illustrated below with reference to above-mentioned technical proposal：
In the utility model, the aluminium strip of tab is in contact close to the part of weld part with more hard weld part, therefore
Its not folding is easily damaged, therefore gel is arranged in the intersection of weld part and aluminium strip in the utility model, and gel is wrapped simultaneously
Part aluminium strip and part weld part are covered, the intersection overflexing of aluminium strip and weld part is avoided, so that tab more folding, and should
The structure energy effectively save production time, improve production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram one of aluminium-to-nickel folding tab described in the utility model embodiment；
Fig. 2 is the structural schematic diagram two of aluminium-to-nickel folding tab described in the utility model embodiment.
Description of symbols：
1- nickel strap, 2- aluminium strip, 3- weld part, 4- gel, 41- glue shoulder.
Specific embodiment
In order to facilitate the understanding of those skilled in the art, doing the utility model into one below in conjunction with attached drawing and embodiment
Step detailed description：
Such as Fig. 1-2, a kind of aluminium-to-nickel folding tab, several aluminium strips 2 and nickel strap 1 including alternate setting, adjacent aluminium strip 2
Weld part 3 is mutually overlapped and is welded together to form with the end of nickel strap 1, and the aluminium strip 2 is coated close to one end of the nickel strap 1
There is gel 4, the gel 4 extends towards the nickel strap 1 and covered section weld part 3.
The aluminium strip 2 of tab is in contact close to the part of weld part 3 with more hard weld part 3, therefore its not folding, holds
It is easy to damage, therefore gel 4, gel 4 while covered section is arranged in the intersection of weld part 3 and aluminium strip 2 in the utility model
Aluminium strip 2 and part weld part 3 avoid the intersection overflexing of aluminium strip 2 Yu weld part 3, so that tab more folding, and the knot
The structure energy effectively save production time, improve production efficiency.
One of embodiment, the two sides of gel 4 towards the tab extend to form glue shoulder 41, the glue shoulder 41
Width is 0.7mm.
One of embodiment, the two sides of gel 4 towards the tab extend to form glue shoulder 41, the glue shoulder 41
Width is 2mm.
One of embodiment, the two sides of gel 4 towards the tab extend to form glue shoulder 41, the glue shoulder 41
Width is 3mm.
Glue shoulder 41 is used to increase the width of gel 4, the bonding strength of the gel 4 to increase tab both side surface,
It can increase the folding resistance of gel 4 simultaneously.
One of embodiment, the gel 4 are yellow glue.
One of embodiment, the gel 4 are black glue.
One of embodiment, the gel 4 are white glue.
One of embodiment, the length of the gel 4 are 5.0mm.
One of embodiment, the length of the gel 4 are 5.5mm.
One of embodiment, the length of the weld part 3 are 2.5mm.
One of embodiment, the length of the weld part 3 are 3mm.
One of embodiment, the length of the weld part 3 are 3.5mm.
One of embodiment, the gel 4 at least cover weld part 3, the length of 0.3mm.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
