[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] A busbar for convenient terminal connection of a switch cabinet comprises a busbar 1 and a wiring clamp module 2 which is detachably combined with the busbar 1. A screw hole seat 3 is provided on one side of the wiring clamp module 2. A clamping screw 4 penetrates the screw hole seat 3 and extends into the wiring clamp module 2. The end of the clamping screw 4 is rotatably connected to a wire pressing plate 7. The exposed wire end 6 of the end of a power line 5 is detachably extended from the upper end of the wiring clamp module 2 into the interior thereof and is clamped on the busbar 1 by the wire pressing plate 7.

[0020] like Figure 1 As shown in the figure, the bus copper bus 1 and the terminal clamp module 2 are detachably connected. The number of terminal clamp modules 2 provided is equal to the number of devices requiring a DC power supply, and no waste is caused. The bus copper bus 1 has an extra length for easy maintenance or subsequent expansion. The bus copper bus 1 is divided into a positive electrode bus and a negative electrode bus, and a ground bus can also be provided.

[0021] like Figure 3 As shown in the figure, the above-mentioned wiring clamp module 2 is provided with a hollow rectangular frame 21, two upper and lower abutment plates 22 on one side of the frame 21, a bus inlet 23 for the industrial bus copper bus 1 to enter is formed between the two abutment plates 22, the screw hole seat 3 is located on the other side of the frame 21, and a wire hole 24 for the exposed wire end 6 to enter is provided on the top of the frame 21.

[0022] The above-mentioned wire pressing plate 7 is arc-shaped.

[0023] The above-mentioned wire pressing plate 7 is composed of two plates which are at a certain angle.

[0024] The top of the frame 21 is provided with a clamping arch 25 consisting of two plates with a certain angle.

[0025] like Figure 3-5 As shown in the figure, when there is a clamping arch 25, when the wiring clamp module 2 is used, the clamping screw 4 is loosened so that the wire pressing plate 7 is located at the rear end of the frame 21, and then the wiring clamp module 2 is tilted to allow the busbar 1 to enter the interior of the wiring clamp module 2 from the busbar inlet 23, that is, Figure 5 As shown in , then return the terminal clamp module 2 to the correct position. Figure 4 As shown in the figure, the exposed wire end 6 at the end of the power cord 5 is inserted into the gap between the bus copper bar 1 and the wire pressing plate 7, and the clamping screw 4 is tightened. When the wire pressing plate 7 contacts the exposed wire end 6, the bus copper bar 1 will slide downward under the action of the edge of the clamping arch 25, and finally the bus copper bar 1 will be supported by two support plates 22 to achieve the clamping of the exposed wire end 6.
