[0008] By adopting the above technical solution, a screw rod is inserted through the positioning hole, and the screw rod is threadedly connected to the busbar groove housing. The screw rod is used to fix the side plate, the front plate and the limiting cover in position.

[0009] Furthermore, a guide bar is provided on one outer wall of the side plate, and a guide groove matching the guide bar is provided on one outer wall of the busbar housing;

[0010] By adopting the above technical solution, the side plate can slide on the outer wall of the busbar housing by moving the guide bar in the guide groove.

[0011] Furthermore, the outer side wall of the positive plate and the top of the top plate are provided with concave and convex portions, which are composed of concave portions and convex portions, respectively provided on the top of the adjacent top plate and the outer side wall of the adjacent positive plate;

[0012] Furthermore, when the side plate and the front plate are folded into a horizontal state, they can be perfectly embedded inside the limiting cover;

[0013] By adopting the above technical solution, the side plate and the front plate can be stored inside the limiting cover, reducing the space occupied by the joint protection component.

[0014] Furthermore, the concave and convex portions are provided with through holes, and a pin for connection is passed through the through holes;

[0015] By adopting the above technical solution, the docking of the concave and convex parts in the concave-convex part allows the pin to pass through and dock and fix the adjacent top plate and the adjacent front plate to form a protective surface, thereby achieving multi-directional protection of the conductive copper sheet.

[0016] The beneficial effects of this utility model are as follows:

[0017] The utility model features a pull-out side plate, an unfoldable front plate, and a top plate on the outer wall of the busbar trunking housing.

The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Reference Figure 1-4 This utility model embodiment proposes a busbar trunking with joint protection, including a busbar trunking housing 1. Conductive copper sheets 2 protrude from the outer wall of the busbar trunking housing 1, and four limiting covers 3 are symmetrically arranged on the outer wall of the busbar trunking housing 1. A side plate 41 from a joint protection assembly 4 is slidably connected to one side of the outer wall of the busbar trunking housing 1 near the inner side of each of the four limiting covers 3. A front plate 42 is rotatably connected to one end of each side plate 41. When the side plate 41 and the front plate 42 are folded into a horizontal state, they can be perfectly embedded inside the limiting covers 3. The side plate 41 and the front plate 42 can be stored inside the limiting cover 3, reducing the space occupied by the joint protection component 4. A baffle 43 is provided on the other side of the side plate 41. A groove 44 is provided on the top of the side plate 41. A movable frame 45 is slidably connected to the inner side wall of the groove 44. A top plate 46 is rotatably connected to the inner side wall of the movable frame 45. A spring 47 is provided at the bottom of the inside of the groove 44. A limiting block 48 is provided at the bottom of the top plate 46. A limiting groove 49 is provided on the inner side wall of the groove 44 near the outer side of the limiting block 48.

[0027] Positioning holes 5 are provided on one side of the outer wall of the side plate 41, the front plate 42 and the limiting cover 3, and are all on the same horizontal plane. A screw rod passes through the positioning hole 5. The screw rod is threaded to the busbar housing 1. The position of the side plate 41, the front plate 42 and the limiting cover 3 is fixed by the screw rod. A guide bar 6 is provided on one side of the outer wall of the side plate 41. A guide groove 7 is provided on one side of the outer wall of the busbar housing 1 near the outer side of the guide bar 6. By moving the guide bar 6 in the guide groove 7, the side plate 41 can slide on the outer wall of the busbar housing 1.

[0028] A concave-convex part 8 is provided on one outer wall of the positive plate 42 and the top of the top plate 46. The concave-convex part 8 is composed of a concave part and a convex part. The concave part and the convex part are respectively provided on the top of the adjacent top plate 46 and the outer wall of the adjacent positive plate 42. A through hole is provided on the concave-convex part 8. A pin for connection is passed through the through hole. By using the docking of the concave part and the convex part in the concave-convex part 8, the pin can pass through and dock and fix the adjacent top plate 46 and the adjacent positive plate 42 to form a protective surface and realize multi-directional protection of the conductive copper sheet 2.

[0029] The specific implementation method is as follows: When protecting the conductive copper sheet 2 on the busbar housing 1, the side plate 41 is pulled out and protrudes from the conductive copper sheet 2 on the busbar housing 1 by sliding guide on the outer side wall of the side plate 41. Under the limit of the baffle 43, after the side plate 41 is pulled out to the maximum distance, the front plate 42 loses the limit of the limit cover 3 and is rotated 270 degrees. The front plate 42 is rotated to the front end of the conductive copper sheet 2. The pin passes through the concave and convex parts 8 on the two front plates 42 and the two front plates 42 are fixed together. The protective surface formed by the two front plates 42 can protect the front end of the conductive copper sheet 2.

[0030] At this time, pull out the top plate 46 in the groove 44 and rotate the top plate 46 90 degrees. The top plate 46 rotates to the top of the conductive copper sheet 2. Use the pin to pass through the concave and convex parts 8 on the two top plates 46 to fix the two top plates 46 together. The protective surface formed by the two top plates 46 can protect the top of the conductive copper sheet 2.

[0031] With the protection of the two side plates 41, both sides of the conductive copper sheet 2 are protected, thus protecting all five sides of the conductive copper sheet 2.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
