Description
Technical field
The utility model belongs to field of batteries, and particularly a kind of cylindrical aluminum hull girdles the waist sealing positive and negative electrodes in same to the lithium ion battery of drawing.
Background technology
At present, cylinder type lithium battery is on the market all generally adopt the hard material external packings such as stainless steel.Due to lithium battery when occurring damaged to leak, overcharge, high temperature can produce gas, can not get discharging in time for preventing gas setting off an explosion, traditional way has leakage port on the head of positive pole.For cylinder type lithium battery, be all generally that the planar base shell of the other end is negative pole with the outstanding head in one end for positive pole.During use, the mode of serial connection that adopts provides Large Copacity, powerful voltage and current charger equipment use more.As adopted the mode of connect in parallel, also need the battery case putting into parallel connection structure just can use, use and be subject to certain restrictions, very inconvenient, difficulty meets the instructions for use of the different occasion of connection in series-parallel.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of use safety and convenience, and the simple cylindrical aluminum hull of manufacturing process girdles the waist sealing positive and negative electrodes in same to the lithium ion battery of drawing.
For achieving the above object, a kind of cylindrical aluminum hull that the utility model provides girdles the waist sealing positive and negative electrodes in same to the lithium ion battery of drawing, comprise housing, housing built with core of lithium ion cell, and on housing, be provided with the positive pole conductor and cathode conductor that are connected with core of lithium ion cell.Housing comprises body and cap, and body is semienclosed container, and wherein, the bottom of body is provided with explosion-proof impression.Cap is rubber stopper, positive pole conductor is connected the positive guide pin extended to through rubber stopper outside housing, cathode conductor is connected the negative guide pin extended to through rubber stopper outside housing, and positive guide pin and negative guide pin are drawn in the same way.
In some embodiments, explosion-proof impression is " one " font or " W " shape or arc.
In some embodiments, cap is the end cap be packaged on body, positive pole conductor is on end cap, be provided with the anode ear with core of lithium ion cell conducting, and cathode conductor is on end cap, be provided with the negative electrode lug with core of lithium ion cell conducting, and anode ear and negative electrode lug are drawn in the same way.
In some embodiments, the opening part of body is provided with the cannelure with a tight waist tightening up opening.
The beneficial effects of the utility model have use safety and convenience, and the simple effect of manufacturing process.Due to housing packaging core of lithium ion cell, and draw through end cap or rubber stopper draw positive and negative guide pin, facilitate lithium ion battery and access in serial or parallel connection mode when different electrical equipment uses.In addition, housing bottom has been provided with explosion-proof impression, effectively releases lithium ion battery and produce gas in not situation, prevents gas to drain not in time and the blast that causes occurs.Achieve use safety and effect easily.Again because the opening part of body adopts roll with a tight waist and rolling enclosuring structure, production efficiency is high, and package quality is reliable.Achieve the simple effect of manufacturing process.
