The varied in thickness scope that constitutes every layer printed circuit board (pcb board) of wiring board in addition is 0.15 millimeter, therefore, in the preparation cell process, easily because the accumulation of the thickness variation of multilayer board, the thickness error that causes wiring board increases, especially when ultrasonic pressing battery case, may therefore cause battery battery core just/battery power down that negative pole lead-out tablet and wiring board sealing-off cause, even fall electronic devices and components on the wiring board of shake.Be which kind of situation takes place all can produce waste product.
In sum as can be known, the battery of prior art still can not satisfy the requirement of no lead-tin soldering, and the thickness variation of wiring board can cause the battery waste product to produce.
The utility model content
The purpose of this utility model is to overcome the shortcoming that the leaded and wiring board variation of prior art battery battery core and wiring board connection welding easily causes the battery waste product, and a kind of not leaded and packaged battery that the wiring board variation influence is little is provided.
The utility model provides a kind of packaged battery, comprise battery battery core 6, wiring board 3 and encapsulate their battery case, described battery battery core 6 comprises anode and cathode terminals, and wherein, the anode and cathode terminals of described battery battery core 6 is connected with wiring board 3 by resilient, conductive member 4 respectively.
Battery provided by the utility model, owing to adopt resilient, conductive member elasticity connection line plate and battery battery core, therefore the soldering connected mode that has replaced prior art has been cancelled the operation of soldering and wicking when the preparation battery, thus a difficult problem that does not exist no lead-tin soldering to bring.The elastic force of resilient, conductive member can guarantee that wiring board is communicated with the effective of battery battery core, prevents the two loose contact.The deformation of resilient, conductive member simultaneously can remedy the wiring board varied in thickness that the printed circuit board (PCB) variation causes, thereby the power down that causes when preventing the battery assembling and the shake of electronic devices and components fall.In addition, resilient, conductive member can also play the effect of buffer battery external impact force.The battery that the utility model provides has reached the unleaded environmental requirement of battery, and quality is good, production qualification rate height.
