And as shown in Figure 1, moulding resin spare 140 can comprise a plurality of openings 141, a plurality of hole 142 and active paper 143.Opening 141 can be positioned to correspondingly, make electrode terminal 131 can pass it and be connected with outside with the electrode terminal 131 of protective circuit plate 130.Active paper 143 can by a plurality of holes 142 the inboard of polymer battery group 100, be protective circuit plate 130 around humidity detecting function is provided.In view of the above, a plurality of holes 142 can be connected with protective circuit plate 130, can link active paper 143 simultaneously with a plurality of holes 142 on the anterior face that covers moulding resin spare 140.
Therefore, polymer battery 110 can be encapsulated in the inboard of shell body 120, can link two lids 150 and moulding resin spare 140 simultaneously to surround the periphery of shell body 120, as shown in Figure 1.Be not only limited in theory, can believe to adopt moulding resin spare 140 and cover 150 to be attached to the bulk strength and the stability that can improve polymer battery group 100 on the shell body 120 symmetrically.
In this; should be noted that; can the electrode tap 111 of polymer battery 110 can be positioned on the outside of shell body 120 simultaneously, to help the electrical connection between polymer battery 110 and the protective circuit plate 130 by shell body 120 encapsulation polymer batteries 110.
The polymer battery group 100 of an embodiment of the present invention also can comprise insulating surface 161.Insulating surface 161 can be set to upper surface, rear surface and the lower surface of overlie polymer battery, make that insulating surface 161 can be between shell body 120 and polymer battery 110, to prevent electrical short.Insulating surface 161 can be formed by any material that those skilled in the art determine, it can use any conventional adhesive as surperficial adhesive tape and so on.In view of the above, the linking that can be between shell body 120 and the polymer battery 110 of the bond properties of insulating surface 161 brings added strength.In addition, can improve coupling power (coupling power) by viscosity insulating surface 161.
The polymer battery group 100 of an embodiment of the present invention also can comprise label 162.Label 162 can be adhered to the outer surface of shell body 120, promptly the outer surface with first outside plate 121, rear portion engagement plate 120a and second outside plate 125 is connected.Label 162 can be provided for providing the space of manufacturing information.
Fig. 4-5 provides the details about the component structure of the battery pack 100 of an embodiment of the present invention.Particularly, shell body 120 can form can provide the hollow hexagon of memory space housing therein.More specifically, shown in Fig. 4 A-4B, first outside plate 121 can be used as and can move up and expose the upper cap of the inner space that is used to place polymer battery 110 in the shell body 120.Shown in Fig. 4 C, shell body 120 also can comprise opening 129a, the curved surface 124c that is formed on the electrical connection that helps polymer battery 110 in its front panel, anterior vertical surface 124d and anterior horizontal surface 128b.Curved surface 124c and anterior vertical surface 124d can be positioned at vertical plane and be connected each other.Curved surface 124c can be connected the top part 122 of first outside plate 121 along its vertical side.Anterior horizontal surface 128b can be formed on the front portion of second outside plate 125 of shell body 120.Therefore, can form a plurality of top locking hole 124a that pass curved surface 124c and anterior vertical surface 124d, and can form the bottom locking hole 128a that passes anterior horizontal surface 124b.When shell body 120 was closed, upper and lower locking hole 124a and 128a can be in correspondence with each other, and were coupled with resin, to improve the intensity and the durability of shell body 120.
In this, should be noted in the discussion above that anterior vertical surface 124d and anterior horizontal surface 128b can not be coupled mutually, help between them, to form the opening 129a of preliminary dimension whereby.Therefore, electrode tap 111 and polymer battery 110 can be connected by opening 129a.
Shown in Fig. 5 A, the top periphery part 123 of first outside plate 121 can comprise upper horizontal surface 123a and upper vertical surface 123b.Upper vertical surface 123b can be connected on the upper horizontal surface 123a, and meets at right angles along the downward direction setting and with upper horizontal surface 123a.Upper horizontal surface 123a can parallelly be coupled to the surface, inside of top part 122, shown in Fig. 5 A, makes the position of upper horizontal surface 123a vertically can be lower than top part 122.
