Specifically, the conductive layer in the distribution box provided by the embodiments of the present application is conductive paper, or a conductive adhesive layer is coated on the outer wall of the connection terminal 41 or the inner wall of the connection hole 31, or a conductive adhesive layer is coated on the conductive paper to form a composite conductive layer.
[0031] In some embodiments, please refer to Figure 1 and Figure 4 , Figure 1 is a perspective view of the high-voltage distribution box that simplifies the conductive terminal connection process provided by the embodiments of the present application (exemplarily showing an electrical control device 40), Figure 4 is a front view of the structure of the substrate 10 and the side plate 20 in the high-voltage distribution box that simplifies the conductive terminal connection process provided by the embodiments of the present application. The high-voltage distribution box that simplifies the conductive terminal connection process provided by the embodiments of the present application further includes a limiting strip 50.

Specifically, a plurality of limiting strips 50 are disposed on each side plate 20, and in a direction perpendicular to the third direction Z, the plurality of limiting strips 50 are spaced apart to provide multi-position limiting support for the electrical control device 40.
[0032] In some embodiments, please refer to Figure 1 and Figure 4 , Figure 1 is a perspective view of the high-voltage distribution box that simplifies the conductive terminal connection process provided by the embodiments of the present application (exemplarily showing an electrical control device 40), Figure 4The front view of the substrate 10 and the side plate 20 structures in the high-voltage distribution box that simplifies the conductive terminal connection process provided by the embodiments of the present application.

[0035] Furthermore, at least part of the potting glue layer is arranged in the groove 51. It can be understood that when constructing the potting glue layer, potting glue needs to be poured. Due to the existence of the groove 51, it can be ensured that in the direction perpendicular to the third direction Z, each groove 51 can block and retain a specified amount of potting glue, so as to improve the uniformity of potting glue pouring; at the same time, due to the existence of the limiting strip 50, the contact area between the potting glue layer and the side plate 20 is increased, and the connection strength between the side plate 20, the potting glue layer, and the electric control device 40 is improved.
[0036] In some embodiments, please refer to Figure 3 , Figure 3A cross-sectional view of the connection structure of the substrate 10, the first limiting platform 60, the second limiting platform 70 and the conductive busbar 30 in the high-voltage distribution box for simplifying the conductive terminal connection process provided by the embodiment of the present application.

Along the third direction Z, the first limiting platform 60 is disposed on the side of the first opening 11 close to the side plate 20. It can be understood that when the conductive busbar 30 is disposed in the first opening 11, the position of the conductive busbar 30 in the third direction Z can be limited by the first limiting platform 60 to meet the position setting requirements of the conductive busbar 30.
[0037] In some embodiments, please refer to Figure 3 , Figure 3 A cross-sectional view of the connection structure of the substrate 10, the first limiting platform 60, the second limiting platform 70 and the conductive busbar 30 in the high-voltage distribution box for simplifying the conductive terminal connection process provided by the embodiment of the present application.

Specifically, the second limiting platform 70 is cylindrical, and the second limiting platform 70 is integrally formed with the connection terminal 41. When the connection terminal 41 is a cylindrical terminal and the connection hole 31 is a round hole, the basic dimensions of the connection terminal 41 and the connection hole 31 are the same.

At least a part of the conductive busbar 30 is disposed in the first opening 11, and a connection hole 31 is formed in the conductive busbar 30. The electrical control device 40 includes a connection terminal 41. At least a part of the connection terminal 41 is disposed in the connection hole 31 and is in interference fit with the connection hole 31 to realize the connection between the electrical control device 40 and the conductive busbar 30. In the present application, the connection terminal 41 of the electrical control device 40 and the connection hole 31 of the conductive busbar 30 are directly connected by interference fit to realize the electrical connection between the electrical control device 40 and the conductive busbar 30.
