A containing groove 12 is formed on the outer peripheral surface of the protective sleeve 1 and communicates with the installation slot 11, the containing groove 12 is formed on the end surface of the protective sleeve 1 where the opening surface of the installation slot 11 is located, and the containing groove 12 extends through the side wall of the protective sleeve 1 along the radial direction of the opening surface of the installation slot 11, and the containing groove 12 contains the connecting band 2.

[0034] Referring to Figure 2It also includes a copper sheet 6, and a protective sleeve 1 is integrally injection molded onto the copper sheet 6, so that the protective sleeve 1 covers the copper sheet 6 and protects it. The mounting groove 11 is connected to the mounting space of the copper sheet 6, and the mounting groove 11 allows bolts to be inserted. The copper sheet 6 has a through hole 61 for the bolts to pass through. The copper sheet 6 is fixedly connected to the battery module by bolts, and the copper sheet 6 and the battery module are electrically connected. The cap 3 is inserted into the mounting groove 11 to seal the opening of the mounting groove 11 and to provide waterproof and insulating protection for the copper sheet 6 and the bolts.

[0035] Reference Figure 2 The cap 3 is made of a flexible insulating material. The cap 3 includes a handle 31 and a mounting part 32. The handle 31 is for the operator to hold, and the mounting part 32 is inserted into the mounting groove 11. The outer side wall of the mounting part 32 abuts against the inner wall of the mounting groove 11 to achieve a seal. The diameter of the handle 31 is smaller than the diameter of the mounting part 32.

[0036] Reference Figure 2 A guide slope 321 is formed on the outer peripheral surface of the mounting part 32. The guide slope 321 is formed on the end of the mounting part 32 that is inserted into the mounting groove 11. A clearance groove 33 is provided on the side wall of the cap 3 near the copper sheet 6. The guide slope 321 is the chamfer between the side wall of the end of the mounting part 32 where the opening surface of the clearance groove 33 is located and the outer ring side wall of the mounting part 32. The guide slope 321 is inclined in a direction that is closer to the central axis of the cap 3 the further away from the opening surface of the mounting groove 11. The guide slope 321 is used to guide the mounting part 32 to be inserted into the mounting groove 11, and makes the mounting part 32 tighter and tighter, eventually deforming and interfering with the inner wall of the mounting groove 11, ensuring the connection stability between the cap 3 and the protective sleeve 1.

[0037] Reference Figure 2 The clearance groove 33 extends in the opposite direction to the installation direction of the cap 3, and the clearance groove 33 is used to accommodate bolts.

[0038] Reference Figure 2 A limiting boss 4 is integrally formed on the inner wall of the mounting groove 11. The limiting boss 4 is annular, which makes the mounting groove 11 and the copper sheet 6 mounting space connected. The limiting boss 4 abuts against the side wall of the end of the mounting part 32 at the outer edge of the opening surface of the clearance groove 33 to limit the depth of the mounting part 32 inserted into the mounting groove 11.

[0039] Reference Figure 1 and Figure 2 A positioning groove 13, which communicates with the mounting groove 11, is provided on the outer peripheral surface of the end of the protective sleeve 1 away from the cap 3. The positioning groove 13 extends along the extension direction of the central axis of the mounting groove 11 and penetrates the side wall of the protective sleeve 1 away from the cap 3. The positioning groove 13 is used to insert and cooperate with the positioning structure on the battery module to initially fix the protective sleeve 1 and facilitate the installation of bolts.

[0040] The use principle of the battery connecting line in the embodiment of the application is as follows: first, the protective sleeve 1, the connecting band 2 and the cap 3 are integrally injection molded on the copper sheet 6; an operator preliminarily positions the protective sleeve 1 on the battery module through the positioning groove 13, completely fixes the protective sleeve 1 on the battery module through the bolt, and realizes the electrical connection between the copper sheet 6 and the battery module; finally, the cap 3 is covered, so that the mounting portion 32 is in interference fit with the inner wall of the mounting groove 11, until the end of the mounting portion 32 abuts against the limiting boss 4, and the connecting band 2 is inserted into the containing groove 12.

[0042] With reference to Figure 3 Different from embodiment 1, the protective sleeve 1 is provided with the locking structure 5 in the embodiment, the locking structure 5 locks the connecting band 2, so that the connecting band 2 is fixed in the containing groove 12. The locking structure 5 includes two locking blocks 51 respectively mounted on the two opposite inner walls of the containing groove 12, the two locking blocks 51 are symmetrically arranged, and the two locking blocks 51 extend towards the direction of closing the opening face of the containing groove 12. The locking block 51 is made of elastic material. The locking block 51 abuts against the connecting band 2, and the connecting band 2 is fibered in the containing groove 12.

[0043] With reference to Figure 3 The side wall of the locking block 51 is provided with the limiting groove 511 extending along the direction close to the central axis of the cap 3, so that the cross-sectional shape of the locking block 51 is in the shape of “L”. The opposite side walls of the two limiting grooves 511 abut against the two side edges of the connecting band 2 in the width direction; the other inner wall face of the limiting groove 511 abuts against the upper end face of the connecting band 2, and cooperates with the inner wall of the containing groove 12.

[0044] When the operator covers the cap 3, the connecting band 2 deforms the locking block 51, until the connecting band 2 is inserted into the containing groove 12, and the locking block 51 restores to the original state, and limits the connecting band 2.

[0045] Embodiment 3

[0046] With reference to Figure 4 Different from embodiment 1, the diameter of the handheld portion 31 is greater than the diameter of the mounting portion 32 in the embodiment, when the mounting portion 32 is inserted into the mounting groove 11, the side wall of the handheld portion 31 close to the mounting portion 32 abuts against the outer edge of the mounting groove 11, indicating that the cap 3 is installed in place.
