[0059] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 As shown, when the second interlocking member 32 is located at the second position, the second interlocking member 32 can block the movement of the high-voltage connection assembly 20 in the direction of being separated from the second mounting hole 12 (for example, the upward direction as shown in Figure 2 ), so that the installation of the high-voltage connection assembly 20 in the second mounting hole 12 is reliable, and the problems such as falling off are avoided, and the problems such as electric shock caused by the removal of the high-voltage connection assembly 20 from the second mounting hole 12 by the personnel during the working process are avoided, the risk of live operation of the personnel is effectively prevented, and the safety is ensured.

[0060] It should be noted that, for the convenience of description, the directions such as "up", "down", "left", "right", "front" and "back" in the utility model are based on the direction relationship shown in the drawings, and are not limited to the direction in the actual application process.
