[0048] In some embodiments, the conductive block assembly 100 includes a second output row 140, one end of the second output row 140 is mounted to the base 110 and connected with the mounting portion 121 of the first output row 120, and the other end of the second output row 140 extends out of the base 110 to be connected with a battery cell located outside the conductive block assembly 100.

[0071] Please refer to Figure 5 In some embodiments, the base 110 comprises a main body 118 and a mounting assembly 119 connected with each other. The side of the main body 118 away from the mounting assembly 119 is provided with a first opening 111, a mounting space 112 and a second opening 113.

[0072] In some specific embodiments, a mounting groove can be formed on the main body 118 along the first direction, so that the mounting groove penetrates through the opposite ends of the main body 118, so that the main body 118 can sequentially form the first opening 111, the mounting space 112 and the second opening 113 in communication along the first direction.

[0073] In some specific embodiments, the main body 118 can include a first side wall 115 and a second side wall 116 arranged along a second direction perpendicular to the first direction, and the first side wall 115 is spaced apart from the second side wall 116 to form the first opening 111, the mounting space 112, and the second opening 113.

Since the first mounting member 1191 and the third mounting member 1195 are of the same structure and symmetrically arranged on two sides of the second mounting member 1193, that is, the base 110 can have two mounting modes on the end plate, the first mounting mode is that the first mounting member 1191 is mounted in cooperation with the first matching member, the second mounting member 1193 is mounted in cooperation with the second matching member, and the third mounting member 1195 is mounted in cooperation with the third matching member, and the second mounting mode is that the first mounting member 1191 is mounted in cooperation with the third matching member, the second mounting member 1193 is mounted in cooperation with the second matching member, and the third mounting member 1195 is mounted in cooperation with the first matching member.

Then, the upper cover 130 is assembled in cooperation with the base 110.

[0078] Specifically, please refer to Figure 1 and Figure 14The main body 118 is provided with a first threaded hole 1181. The first threaded hole 1181 can penetrate the main body 118 and extend to the second mounting part 1193. The arrangement direction of the first part 131 and the base 110 is the third direction. Along the third direction, the mounting part 121 of the first output row 120 can be provided with a first through hole 123.

[0079] In some examples, the second mounting part 1193 can be located at the center of the base 110.

[0080] The conductive block assembly 100 provided in the application is assembled first by connecting the mounting assembly 119 of the base 110 with the matching part of the end plate.

The second mounting part 1193 can be configured as a boss, which can be a cylindrical boss. Since the first mounting part 1191, the second mounting part 1193 and the third mounting part 1195 are arranged along the first direction, the direction of the third opening 117 of the base can be correctly placed, that is, the third opening 117 can be correctly directed towards the end of the battery cell, avoiding the workers from assembling in the wrong way.

[0081] The first output row can select any one of the two output directions according to actual needs, and can be locked on the base by bolts. The upper cover 130 can be assembled with the base 110 by a buckle structure. Since the second part 133 is basically the same size as the output row opening of the base 110, that is, the first opening 111 and the second opening 113, after the first output row 120 is mounted on the base 110, the upper cover 130 has only one assembly mode, which has an anti-fumble effect to prevent assembly errors.
