Please refer to FIG. 5 to FIG. 7, which are schematic diagrams of an external force F exerting force on the conductive terminal 120 from one side, wherein FIG. 5 is a schematic diagram of an initial state, FIG. 6 is a schematic diagram of an intermediate state, and FIG. 7 is a schematic diagram of Schematic representation of the final state.

When the external force F acts on the conductive terminal 120 in the direction indicated by the arrow, the contact portion 125 and the hook portion 127 of the conductive terminal 120 move horizontally in the direction indicated by the arrow, and the contact portion 125 and the bent portion 124 are compressed and deformed accordingly until An end of the hook portion 127 abuts against the bottom of the limiting slot 1175 .

Please refer to FIG. 8 , which shows another embodiment of the present invention. The difference between this embodiment and the embodiment shown in FIG. 1 lies in the arrangement of the limiting structure of the terminal groove 117 . In this embodiment, the two limiting blocks 1173 are connected to each other to form an integrated structure, so that the ends of the conductive terminals 120 do not need to protrude laterally to both sides to provide the holding portion 126, but can be directly bent at the end of the contact portion 125. The hook portion 127 is folded. In this case, the lateral compressive force that the battery connector can withstand will be slightly reduced compared with the embodiment shown in FIG. Compared with the traditional battery connector without the design of the limiting groove 1175 and the hook portion 127 , its tolerance to lateral pressure is still greatly improved.
