Similarly, the battery cells 201 arranged along the direction X are electrically connected in series through multiple electrical connectors 2.

[0074] Please refer to Figure 4b As shown, each electrical connection part 21 of each electrical connector 2 is also provided with at least three connection holes 22. At least one connection hole 22 is penetrated by the electrode structure (not shown) of the battery cell 201, so that the electrical connection part 21 is connected to the electrode structure of the battery cell 201 (welding and electrical connection); at least one connection hole 22 is used to be penetrated by the connection column 14 of the wiring harness isolation plate 1, so that the electrical connection part 21 is connected to the wiring harness isolation plate 1 (interference fit connection or thermal riveting); at least one connection hole 22 is used to be penetrated by the wiring harness, so that the electrical connection part 21 is electrically connected to the wiring harness, so that the wiring harness can collect the current signal of the electrical connection part 21.

[0075] The material of the electrical connector 2 includes aluminum, copper or iron.

[0076] The third aspect of the present application embodiment provides a wiring harness isolation plate, please refer to Figure 3a-Figure 3b As shown, the harness isolation plate 1 includes a base plate 11, an I-shaped protrusion 12 and a U-shaped protrusion 13. At least two I-shaped protrusions 12 protrude from the top surface 11a of the base plate 11 along the thickness direction (direction Z) of the base plate 11, and at least two U-shaped protrusions 13 protrude from the top surface 11a of the base plate 11 along the thickness direction (direction Z) of the base plate 11. The above arrangement makes it possible for at least part of the structure of the I-shaped protrusion 12 and the U-shaped protrusion 13 to enhance the bending strength of the substrate 11 regardless of how the I-shaped protrusion 12 and the U-shaped protrusion 13 are distributed relative to the substrate 11, so as to reduce the possibility of bending and deformation of the substrate 11 when subjected to a large external force, and also reduce the bending and deformation of the electrical connector 2 installed on the harness isolation plate 1, thereby reducing the possibility of a virtual electrical connection between the electrical connector 2 and the battery cell 201, and reducing the possibility of electric sparks generated by the connection structure between the electrical connector 2 and the battery cell 201. Therefore, the structural arrangement of the harness isolation plate 1 in the embodiment of the present application can improve the working reliability of the electrical connection between the electrical connector 2 and the battery cell 201 and improve the safety of the battery pack.

[0077] Please refer to Figure 3a and Figure 3b As shown, the I-shaped protrusion 12, the U-shaped protrusion 13 and the substrate 11 enclose to form a first installation groove 1a, and the first installation groove 1a is used for installing a wire harness (not shown in the figure). Please refer to Figure 3a and Figure 3b As shown, the U-shaped protrusion 13 and the substrate 11 enclose to form a second installation groove 1b, and the second installation groove 1b is used for installing the electrical connector 2 as shown in Figure 2 As shown. Among them, the first installation groove 1a and the second installation groove 1b are communicated so that the wire harness and the electrical connector 2 are connected. That is, the I-shaped protrusion 12 and the U-shaped protrusion 13 in the embodiment of the present application are not only used to improve the bending strength of the substrate 11, but also used as the structure for forming the first installation groove 1a. The U-shaped protrusion 13 in the embodiment of the present application is not only used to improve the bending strength of the substrate 11, but also used as the structure for forming the second installation groove 1b. Therefore, the wire harness separator 1 in the embodiment of the present application realizes two functions simultaneously by using the same structure. Compared with the wire harness separator in the prior art, which respectively includes a structure for improving the bending strength and a structure for enclosing and forming an installation groove, the structure of the wire harness separator 1 in the embodiment of the present application has a higher degree of structural compactness. The wire harness separator 1 with a higher degree of structural compactness occupies less space in the battery pack, so that the wire harness separator 1 can install more electrical connectors 2, wire harnesses and other parts in the battery pack.

[0078] In other embodiments, two U-shaped protrusions 13 and the substrate 11 can also enclose to form a few first installation grooves 1a.

[0079] Optionally, please refer to Figure 5a-Figure 5b As shown, the I-shaped protrusion 12 includes a first section 121, a second section 122 and a third section 123. The first section 121 includes a first end 121a and a second end 121b which are oppositely arranged. The first end 121a is connected to the second section 122, and the second end 121b is connected to the third section 123. The first section 121 is arranged along the width direction (direction Y) of the substrate 11, and the second section 122 and the third section 123 are both arranged along the length direction (direction X) of the substrate 11. In this setting, the second section 122 and the third section 123 can increase the bending strength of the substrate 11 for resisting the bending moment M1 about the axis O1. The first section 121 can increase the bending strength of the substrate 11 for resisting the bending moment M2 about the axis O2. Therefore, the setting in the embodiment of the present application can better improve the working reliability of the electrical connection between the electrical connector 2 and the battery cell 201 and better improve the safety of the battery pack.

[0080] Among them, the axis O1 can be regarded as the center line along the direction Y of the second section 122 and the third section 123, and the axis O2 can be regarded as the center line along the direction X of the first section 121.

[0081] In other embodiments (not shown in the figures), the first section 121 may be disposed along the length direction (direction X) of the substrate 11 , and the second section 122 and the third section 123 may be disposed along the width direction (direction Y) of the substrate 11 .

[0082] Optionally, see Figure 6a , Figure 6b and Figure 6c As shown, the U-shaped protrusion 13 includes a fourth section 131, a fifth section 132 and a sixth section 133. The fourth section 131 includes a third end 131a and a fourth end 131b arranged opposite to each other. The third end 131a is connected to the fifth section 132, and the fourth end 131b is connected to the sixth section 133. The fourth section 131 is arranged along the length direction (direction X) of the substrate 11, and the fifth section 132 and the sixth section 133 are both arranged along the width direction (direction Y) of the substrate 11. Under this arrangement, the fifth section 132 and the sixth section 133 can increase the bending strength of the substrate 11 for resisting the bending moment M4 around the axis O4. The fourth section 131 can increase the bending strength of the substrate 11 for resisting the bending moment M3 around the axis O3. Therefore, the arrangement of the embodiment of the present application can better improve the working reliability of the electrical connection between the electrical connector 2 and the battery cell 201 and better improve the safety of the battery pack.

[0083] The axis O3 may be regarded as the center line of the fourth segment 131 along the direction Y, and the axis O4 may be regarded as the center line of the fifth segment 132 and the sixth segment 133 along the direction X.

[0084] In other embodiments, please refer to Figure 6d As shown, the fourth section 131 can be arranged along the width direction (direction Y) of the substrate 11, and the fifth section 132 and the sixth section 133 can both be arranged along the length direction (direction X) of the substrate 11.

[0085] Optionally, any structure of the second section 122, the base plate 11 and the U-shaped protrusion 13 encloses the first installation groove 1a. For example, the second section 122, the base plate 11 and the fifth section 132 or the sixth section 133 of the U-shaped protrusion 13 can enclose the first installation groove 1a. The arrangement of this embodiment has the above-mentioned effect of a high degree of structural compactness of the wiring harness isolation plate 1. It will not be repeated here.

[0086] If the second section 122, the substrate 11 and the fifth section 132 are enclosed to form the first installation groove 1a, the size of the second section 122 along the direction X may be the same as or different from the size of the fifth section 132 along the direction X. If the second section 122, the substrate 11 and the sixth section 133 are enclosed to form the first installation groove 1a, the size of the second section 122 along the direction X may be the same as or different from the size of the sixth section 133 along the direction X.

[0088] Optionally, any structure of the third section 123, the base plate 11 and the U-shaped protrusion 13 encloses the first installation groove 1a. For example, the third section 123, the base plate 11 and the fifth section 132 or the sixth section 133 of the U-shaped protrusion 13 can enclose the first installation groove 1a. This embodiment has the above-mentioned effect of a high degree of structural compactness of the wiring harness isolation plate 1. It will not be repeated here.

[0089] If the third section 123, the substrate 11 and the fifth section 132 are enclosed to form the first installation groove 1a, the size of the third section 123 along the direction X may be the same as or different from the size of the fifth section 132 along the direction X. If the third section 123, the substrate 11 and the sixth section 133 are enclosed to form the first installation groove 1a, the size of the third section 123 along the direction X may be the same as or different from the size of the sixth section 133 along the direction X.

[0090] In other embodiments (not shown in the figures), the third section 123 , the base plate 11 and the fourth section 131 of the U-shaped protrusion 13 may be combined to form the first installation groove 1 a .

The second section 122 located between the first section 121 and the second installation slot 1b can form a limiting effect on the other wiring harness in the direction opposite to the direction Y, so that the other wiring harness can be better placed on the wiring harness isolation plate 1 in a direction parallel to the direction X.

[0094] Optionally, the third section 123 is located between the first section 121 and the second mounting groove 1 b.

[0095] Since the second installation slot 1b is used to install the electrical connector 2, part of the wiring harness will extend from the first installation slot 1a to the second installation slot 1b and be connected to the corresponding electrical connector 2, but other wiring harnesses will continue to extend in a direction parallel to the direction X, that is, other wiring harnesses will pass through the second installation slot 1b and the side of the electrical connector 2. The third section 123 located between the first section 121 and the second installation slot 1b can form a limiting effect along the direction Y for the other wiring harnesses, so that the other wiring harnesses can be better placed on the wiring harness isolation plate 1 in a direction parallel to the direction X.
