Description
Technical field
The utility model belongs to technical field of lithium ion, relates in particular to a kind of lithium ion battery temperature current protector installation component.
Background technology
Universal along with the mobile communication equipments such as mobile phone, notebook, digital camera, multimedia equipment, increasing as the demand of the lithium ion battery of the said equipment power supply especially Soft Roll rectangular lithium ion battery.But because lithium is the very active element of a kind of chemical property, the safety problem of lithium ion battery is the required matter of utmost importance of facing, solving in production, use procedure always.If the lithium ion battery improper use overcharges, crosses and to put or short circuit when causing discharging current excessive, very easily cause battery temperature sharply to raise, cause battery burning, even blast, surrounding environment or user are damaged, injure.
For fear of the generation of above-mentioned dangerous situation, in the lithium ion battery manufacture process by the method that adopts the external temperature current protector improve lithium ion battery anti-overcharge, cross and put and the ability of overcurrent.The temperature current protector body element is generally fuse or thermistor, for convenience of being connected with the lug of lithium ion battery, is welded with metal-ware at body element two ends, forms U-shaped member together with body element, as shown in Figure 1.The metal-ware of one end welds together as the positive pole ear of connector and lithium ion battery; the metal-ware of the other end substitutes the positive pole ear that former positive pole ear becomes lithium ion battery and the whole member of temperature current protector, and temperature current protector and lithium ion battery are cascaded.
This U-shaped member is simple, practical, assembling is firm, but because the length of body element in temperature current protector is generally 6-10mm, and the width of connector and installed part is 6mm, so the width of whole member is at least 20-28mm.And along with the equipment volume such as mobile phone, notebook are more and more less; the size of matching used lithium ion battery is also more and more less; the distance that there is no the metal-ware maintenance 6-10mm at enough confession temperature current protector two ends, space; temperature current protector is had to abandon U-shaped member and is adopted F type member, as shown in Figure 2.This F type member folds into the other end with the metal-ware of body element one end, reduced the distance between two metal-wares.It is relatively poor that but this F type member is installed rear stability, the easy perk in two ends, and the more U-shaped length of the length of metal-ware; increased the resistance of member; can produce more heat when high current charge-discharge, temperature current protector is more easily moved, affect the normal use of battery.
The problem that warps for solving F type member two ends, Chinese patent CN202103132U proposes on folded metal-ware, groove to be set, and to reduce stress, prevents the two ends perk.But the method has reduced groove intensity, and the frequent turnover to this annex in the course of processing easily causes the groove fracture.And because groove metal-ware width reduces, further increased resistance, and use the temperature current protector of this member just might move under the lithium ion battery running current, affected the normal use of lithium ion battery.
In view of this, necessaryly provide a kind of normal temperature current protector installation component that uses of battery that do not affect.
