More specifically, the second mounting structure 22 includes a recessed cavity formed on the inner wall surface on the rear side of the mold cavity 2, and second mounting columns formed on both sides on the inner wall surface of the bottom of the mold cavity 2. A second mounting groove is formed on the second mounting column, and a connecting portion matching the second mounting groove is also formed at the corresponding position of the negative electrode conductive member 4. The negative electrode conductive member 4 is fixed in the mold cavity 2 through the cooperation of the connecting portion and the second mounting groove, and the recessed cavity prevents the negative electrode conductive member 4 from contacting the surrounding wall of the battery 5 after installation. Therefore, the setting of the second mounting structure 22 ensures reasonable contact between the negative electrode conductive member 4 and the negative electrode of the battery 5, and the contact connection effect between the inner end of the negative electrode conductive member 4 and the negative electrode of the battery 5 is better, and the power supply connection is more stable and reliable.

The setting of the elastic sheet 26 makes the stop member 25 have better elasticity. When the battery 5 is installed in place, the negative electrode of the battery 5 forms a downward pressure on the fourth sheet 21. At this time, the inner end of the negative electrode conductive member 4 will also bend and deform. When the stop member 25 is pressed down by the inner end of the negative electrode conductive member 4 and forms a limit with the bottom of the cavity 2, the stop member 25 can make the fourth sheet 21 firmly form a close contact with the negative electrode of the battery 5.
