Embodiment
And the utility model is described in detail below with reference to the accompanying drawings in conjunction with the embodiments.It should be noted that, when not conflicting, the feature in following embodiment and embodiment can combine mutually.
Flexible-packed battery side seal end socket in one of them embodiment of the utility model comprises upper cover and bottom head.
As Figure 1-3, the upper strip of paper used for sealing 12 that described upper cover 10 comprises upper bed-plate 11 and is arranged on described upper bed-plate 11, the end face of described upper strip of paper used for sealing 12 is upper working face 12a, and the one end on described upper working face 12a Width is provided with the upper limit breach 13 extended along upper working face 12a length direction.More preferably, described upper limit breach 13 is right-angle notch, and described upper limit breach 13 is greater than 0.5mm along the width W 1 on described upper working face 12a Width, is preferably 0.5mm, described upper limit breach 13 is greater than 0.5mm along the height H 1 in described upper strip of paper used for sealing 12 short transverse, is preferably 0.5mm.Further preferably, the side of described upper strip of paper used for sealing 12 is provided with raised line 14 and forms described upper limit breach 13.
As Figure 4-Figure 6, the lower strip of paper used for sealing 22 that described bottom head 20 comprises lower bottom base 21 and is arranged on described lower bottom base 21, the end face of described lower strip of paper used for sealing 22 is lower working face 22a, and the one end on described lower working face 22a Width is provided with the lower limit breach 23 extended along lower working face 22a length direction.More preferably, described lower limit breach 23 is right-angle notch, and described lower limit breach 23 is greater than 0.5mm along the width W 2 on described lower working face 22a Width, is preferably 0.5mm, described lower limit breach 23 is greater than 0.5mm along the height H 2 in described lower strip of paper used for sealing 22 short transverse, is preferably 0.5mm.Further preferably, the side of described lower strip of paper used for sealing 22 is provided with lower raised line 24 and forms described lower limit breach 23.
