Embodiment
Below with reference to Fig. 3 to Fig. 5 embodiment of the present utility model is elaborated.
Fig. 3 is the vertical view that expression utilizes the battery pack of forced connector connection of the present utility model.Fig. 4 is the front view of the brace that adopts in the battery pack of expression battery cell of the present utility model.Fig. 5 is the front view that expression utilizes the battery pack of forced connector connection of the present utility model.
As Fig. 3 and shown in Figure 5, the brace 300 that constitutes by electric conducting material between the battery cell 100 connects, and is respectively equipped with the column cap 200 that protrudes in the battery cell upper surface in battery cell 100.On brace 300, offer and described column cap 200 position corresponding opening 310.Here, the shape of opening 310 is circular.By be pressed into this brace 300 to column cap 200 opening 310 is connected with battery cell 100 buckles.Thus, finish electrical connection between the battery cell.
Further, on column cap 200, be provided with groove (not shown).Therewith accordingly, also be provided with clip 301～304 on the opening 310 of brace 300.By being pressed into brace 300 to column cap 200, the mutual buckle between the clip 301～304 of the opening by groove on the column cap 200 and brace 300 makes column cap 200 and brace 300 realize being electrically connected.
Particularly, in Fig. 4, clearly show the structure of the of the present utility model forced brace 300 that is used to connect battery cell.As shown in Figure 4, on brace 300, on each opening 310,2 clips 301 and 302 and 303 and 304 are set respectively.Thus, groove on the column cap 200 and clip 301～304 can firmly make the mutual buckle of opening of column cap 200 and brace 300, guarantee reliable and firm electrical connection between column cap 200 and the brace 300.
