[embodiment]

Below mainly reach specific embodiment in conjunction with the accompanying drawings the structure of cells in notebook computer be further described.

As shown in Figure 1 to Figure 3, the cells in notebook computer of the present embodiment connector 50 that comprises battery case 20, electric core 30, printed circuit board (PCB) 40 and be used for being connected with other equipment.Wherein, connector 50 electrically connects by printed circuit board (PCB) 40 and electric core 30, and electric core 30 and printed circuit board (PCB) 40 are contained in the battery case 20.Connector 50 is fixing by battery case 20.

As Fig. 4, shown in Figure 5, battery case 20 comprises first housing 21 and second housing 22 of mutual engaging.First housing 21 roughly is tabular, and the one lateral edges has extended to form protuberance 211, and the edge of protuberance 211 offers first breach 212.

Second housing 22 comprises and roughly is flat base plate 221 and vertical extent forms around the base plate 221 side plate 222.The groove 223 of electric core 30, printed circuit board (PCB) 40 and connector 50 is accommodated in base plate 221 and side plate 222 formation one.Wherein, groove 223 comprises first groove 224 of accommodating electric core 30 and accommodates printed circuit board (PCB) 40 and second groove 225 of connector 50.Second groove 225 cooperates side plate 222 to form by the lateral edges extension of base plate 221.Near present embodiment second groove 225 side plate 222 offers second breach 226, and side plate 222 is provided with draw-in groove 227 in the both sides of second breach 226.

Shown in Fig. 6 a to Fig. 6 b, electric core 30 comprises that sub

electric core

320 and 330, two electric cores 320,330 of son of connecting by jockey 310 electrically connect by jockey 310 and printed circuit board (PCB) 40.Electricity core 30 lies in first groove, 224 inside.Jockey 310 comprises between two electric cores 320,330 of son, and is used for the lead 311 of connexon electricity core 320,330.
