[0027] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 This utility model provides a technical solution: an isolated controller junction box, including: a box body 1, a box cover 2, an isolation mechanism 3 and a wire pressing mechanism 4; the upper surface of the box body 1 is connected to the box cover 2 by screws, and the isolation mechanism 3 and the wire pressing mechanism 4 are connected to the inner wall of the box body 1; the isolation mechanism 3 includes a lower partition 301 fixedly connected to the inner wall of the box body 1, the upper surface of the lower partition 301 abuts against an upper partition 302, the upper partition 302 is slidably connected to the inner wall of the box body 1, and the upper partition 302 is fixedly connected to the bottom of the box cover 2.

[0028] In this isolated controller junction box, a sealing gasket is placed between the box body 1 and the box cover 2. After the box cover 2 is installed on the box body 1 with screws, the sealing gasket is squeezed to seal it. The lower partition 301 and the upper partition 302 separate the space of the box body 1. The outer sides of the box body 1 and the box cover 2 have heat dissipation fins to increase heat dissipation capacity.

[0029] exist Figures 1-3 In the middle, a sealing cylinder 303 is placed between the box body 1 and the box cover 2 and between the lower partition 301 and the upper partition 302.

[0030] After removing the cover 2, the two sets of sealing cylinders 303 in this isolated controller junction box can be directly removed and replaced. The sealing cylinder 303 with the corresponding through hole size can be selected according to the diameter of the cable. The two sets of sealing cylinders 303 provide double sealing for the cable, increasing the isolation effect.

[0031] exist Figure 1 , Figure 3 and Figure 5In the middle, a plug rod 304 is fixedly connected to the lower inner wall of the box body 1 near the lower partition 301. A terminal block 305 is slidably connected to the plug rod 304, and the terminal block 305 abuts against the lower part of the box cover 2.

[0032] The isolated controller junction box has a junction box 305 that is a cover-free type. Both sides of the junction box 305 have baffles to increase the isolation effect between the cables. The junction box 305 can be removed from the plug 304 for replacement. It is convenient to replace the junction box 305 in case of stripping, burning or other faults in the future.

[0033] exist Figure 5 In the middle, a U-shaped spring 306 is connected to the lower inner wall of the box 1 away from the plug 304 by screws. A baffle 307 is abutted below the U-shaped spring 306 and is fixedly connected to one side of the terminal block 305.

[0034] The isolated controller junction box has a spring clip 306 made of flexible plastic and stainless steel. By pulling the spring clip 306 to one side, it can be removed from the baffle 307, releasing the restriction on the terminal block 305, so that the terminal block 305 can be removed from the plug 304 for replacement.

[0035] exist Figure 4 and Figure 6 In the middle, the wire pressing mechanism 4 includes a base plate 401 connected to the lower part of the inner wall of the box 1 by screws, and a winding post 402 is fixedly connected to the upper surface of the base plate 401.

[0036] After the cable is connected to the terminal block 305 and passed through the sealing cylinder 303, the cable is wound back and forth several times on the winding post 402 to increase friction and prevent the cable from coming loose from the terminal block 305 when it is subjected to drag.

[0037] exist Figure 6 In the middle, a pressure plate 403 is slidably connected to the winding post 402.

[0038] In this isolated controller junction box, after the cover 2 is placed on the box body 1, the pressure plate 403 slides on the winding post 402, and the pressure plate 403 presses the cable onto the base plate 401 to increase friction.

[0039] exist Figure 6 In the middle, a bidirectional threaded rod 404 is rotatably rotatably passed through the inner wall of the box cover 2 via a sealed bearing. A slider 405 is threadedly connected to the bidirectional threaded rod 404, and the slider 405 is slidably connected to the bottom of the box cover 2.

[0040] When the bidirectional threaded rod 404 is rotated, the bidirectional threaded rod 404 drives two sets of sliders 405 to slide in opposite directions.

[0041] exist Figure 6 In the middle, a transmission plate 406 is rotatably connected to the lower part of the slider 405, and the other end of the transmission plate 406 is rotatably connected to the upper surface of the pressure plate 403.

[0042] In this isolated controller junction box, when the slider 405 slides, it pushes the transmission plate 406 to rotate between the slider 405 and the pressure plate 403, thereby driving the pressure plate 403 to move up and down along the winding post 402, squeezing the cable between the base plate 401 and the pressure plate 403.

[0043] In summary: When using this type of isolated controller junction box, firstly, use a screwdriver to remove the box cover 2, pass the cable through the two sets of sealing cylinders 303 and connect it to the terminal block 305, then wind the cable back and forth on the winding post 402, then put the box cover 2 on the box body 1, install it with a screwdriver, and then rotate the bidirectional threaded rod 404 to tighten the cable to complete the wiring.
