[0021] The technical solution of the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figure 1-6 As shown, the present embodiment provides a junction box for an electric vehicle motor controller, comprising a main body 1, a group of connecting plates 4 are provided on both sides of the outside of the main body 1, a fixing plate 401 is provided at the bottom of the connecting plate 4, a limiting plate 402 is connected to the outside of the fixing plate 401, and sliders 404 are provided on both inner walls of the limiting plate 402, and sliding grooves 403 are provided on both sides of the fixing plate 401, and the sliding grooves 403 are slidably connected with the sliders 404, a sliding hole 411 is provided on one side of the fixing plate 401, a groove 412 is provided on the top of the sliding hole 411, a spring 410 is provided inside the sliding hole 411, and a plurality of plug holes 2 and a group of terminals 3 are provided on both sides of the main body 1.

[0023] like Figure 4 , Figure 5 As shown, the interior of the sliding hole 411 is connected to a moving rod 407, the right end of the moving rod 407 is provided with an external thread and is connected to one side of a limit block 408, and the left end of the spring 410 is against one side of the limit block 408. In this way, the moving rod 407 can be pushed to move by the spring 410.

[0024] like Figure 2 , Figure 3 As shown, a connecting groove 1 is provided at one end of the fixed plate 401, and the connecting groove 1 contacts the bottom of the connecting plate 4. Moving grooves are provided on both sides of the connecting plate 4, and one end of the moving groove corresponds to one end of the sliding groove 403. The slider 404 is slidably connected to the inside of the moving groove. This method facilitates the movement of the limiting plate 402 to one side of the connecting plate 4, and the inside of the limiting plate 402 can contact the outside of the connecting plate 4, thereby limiting the connecting plate 4 through the limiting plate 402.

[0025] like Figure 5As shown, the top of the limit block 408 is welded and fixed to the bottom of the moving frame 405, three plug plates 406 are fixed on the top of the moving frame 405, and the moving frame 405 is arranged inside the groove 412. Three card slots are opened on the top of the groove 412. The overall width and length of the card slots are greater than the overall width and length of the plug plates 406. This method applies pressure to the limit rod to drive the moving frame 405 to move into the groove 412, so that the moving frame 405 drives the plug plates 406 to move.

[0026] like Figure 3 As shown, the three plug plates 406 all penetrate the outside of the fixed plate 401, and three slots are opened on one side wall of the limiting plate 402. The inside of the slots is connected to the outside of the plug plates 406, and the slots are located at the bottom of the slider 404. This method fixes the limiting plate 402 by connecting the plug plates 406 with the slots.

[0027] like Figure 1 , Figure 4 as well as Figure 5 As shown, the interior of the sliding hole 411 is provided with an internal thread, the exterior of the limiting ring 409 is provided with an external thread, and the external thread is adapted to the internal thread, the limiting ring 409 passes through the exterior of the moving rod 407, this method can prevent the moving rod 407 from being separated from the interior of the sliding hole 411 when moving, a connecting groove 2 is provided on the other side of the fixing plate 401, a fixing groove is provided inside the connecting groove 2, and one end of the fixing groove extends to the exterior of the fixing plate 401, this structure helps to connect the fixing plate 401 to a position such as the top of the motor, so as to fix the main body 1.

[0028] like Figure 1-6 As shown, the principle of the electric vehicle motor controller junction box provided in this embodiment is as follows: when the main body 1 needs to be disassembled, the moving rods 407 connected to a group of fixed plates 401 on both sides of the main body 1 are pressed one by one, and the pressed moving rods 407 will move toward the inside of the sliding hole 411, and at the same time, the limit block 408 at the right end of the moving rod 407 will push the spring 410 to move, and at this time, the limit block 408 will also drive the top moving frame 405 to move, so that the three plug plates 406 at the top of the moving frame 405 will move into the groove 412, so that the plug plate 406 and the slot opened on the left wall of the limit plate 402 are released from the limit; push the limit plate 402 to one side, and the slider 404 inside the limit plate 402 can move inside the slide groove 403 set on the fixed plate 401, and at the same time, the limit plate 402 will be separated from the connection groove 1 opened by the connecting plate 4, so that the limit plate 402 releases the limit on the connecting plate 4.
