DETAILED DESCRIPTION

[0022] The utility model is further explained below in combination with the drawings and examples.

[0023] As Figure 1 shown, the perspective view of the cable clamp for electrical cabinet of the utility model is given, Figure 2 and Figure 3 the perspective views of the base and the top cover in the utility model are given respectively, the cable clamp for electrical cabinet of the utility model shown comprises a base 1, a top cover 2 and a compression bolt 3, the base 1 and the top cover 2 are both cuboid in shape as a whole, the upper end of the base 1 is uniformly provided with three arc-shaped lower notches 4, the opening of the lower notch 5 faces upwards, and the base 1 on both sides of each lower notch 4 is provided with a platform 5. The base 1 at the middle position of each lower notch 4 is provided with a vertical first mounting hole 11, the first mounting hole 11 is in the form of penetration, and the bolt inserted into the first mounting hole 11 can fix the base 1 on the inner wall of the electrical cabinet. The two platforms 5 in the middle of the base 1 shown are provided with vertical inner threaded holes 6, and the fixed connection between the base 1 and the top cover 2 is realized through the inner threaded holes 6.

[0024] The top cover 2 is provided with three arc-shaped upper notches 7, the openings of the upper notches 7 face downward, and each upper notch 7 is provided with a baffle 8 on both sides, and the number of baffles 8 on the same side of one upper notch 7 is two, the distance between the two baffles 8 on the front and back sides of the top cover 2 is equal to the thickness of the base 1, so that when the top cover 2 is buckled on the base 1, the baffles 8 on the front and back sides of the base 1 are aligned. The top cover 2 is provided with a connecting hole 9 aligned with the inner threaded hole 6 of the base 1, the compression bolt 3 passes through the connecting hole 9 and is screwed into the inner threaded hole 6, so as to realize the fixed connection of the top cover 2 and the base 1.

[0025] In use, after the top cover 2 and the base 1 are connected by the compression bolt 3 passing through the connecting hole 9 and being screwed into the inner threaded hole 6, the aligned lower notch 4 and the upper notch 7 form a closed hole 10 through which the cable passes; and the clamping depth of the top cover 2 and the base 1 and the shape of the closed hole 10 can be adjusted by adjusting the screwing depth of the compression bolt 3, which can not only ensure that cables with different outer diameters can pass through the closed hole 10 and improve the compatibility of the clamp, but also ensure the compression tightness of the top cover 2 on the cable and the good fastening effect. At the same time, due to the existence of the baffles 8 on both sides of the closed hole 10, adjacent cables of different phases are isolated by the baffles 8, which ensures the electrical isolation between the cables of different phases and ensures the electrical safety of the electrical cabinet.
