The number of the electrical units 12 is at least two, and the number of the electrical units 12 can be adjusted according to actual requirements, and in this embodiment, only three electrical units 12 are described as an example. In addition, the internal structure of each electrical unit 12 is the same, but is independent of each other.

The two sides of the electrical unit 12 are respectively provided with wiring conductive members 121, as shown in the drawing, the wiring conductive members 121 are respectively arranged on the front and rear sides of the electrical unit 12 and are symmetrically arranged. The wire conductors 121 are in electrical communication with structures inside the electrical unit 12, and the other portions of the wire conductors 121 extend outside the electrical unit 12, in particular for making electrical connection with external lines, such as wires or conductive strips or bars, etc.

A gap 122 is disposed between two adjacent electrical units 12, where the gap 122 may extend through two adjacent electrical units 12 or may extend downward from the top surface, so that the lower ends of two adjacent electrical units 12 are disposed in a fitting manner. The height of the gap 122 can be adjusted according to practical requirements.

The partition 13, the partition 13 is connected with the main body 11, where the connection mode may be a plug-in connection or a bolt connection or a paste connection, and those skilled in the art may select according to actual requirements. The fixed separator 13 is located between two adjacent wiring conductive members 121, where the two adjacent wiring conductive members 121 are specifically located on the same side, for example, both the front sides. As shown in the present embodiment, the three electrical units 12 have six wiring conductors 121, so four separators 13 are required to form an isolated fit, where the number of separators 13 may also be increased or decreased according to actual needs. The partition 13 is provided with an extension 133, and the extension 133 extends to the gap 122. With this structure, the extension 133 achieves isolation between the gaps 122, and better achieves the isolation effect.

Specifically, as shown in fig. 3 to 4, the main body 11 is provided with a fixing groove 14, and the partition 13 is fixedly connected with the fixing groove 14. The fixing groove 14 is arranged, so that the fixing effect is better realized, and the partition 13 is fixed firmly. In addition to the present embodiment, the partition 13 may be engaged with the main body 11 by means of bolting, so as to achieve the effect of connection and fixation; or the partition plate 13 can be matched with the main body 11 in a bonding connection mode to realize the effect of connection and fixation.

Specifically, as shown in fig. 1-3 and 5, the partition 13 includes a first protrusion 131 and a second protrusion 132, where the first protrusion 131 and the second protrusion 132 are disposed on two sides of the partition 13, in this embodiment, the first protrusion 131 and the second protrusion 132 are located on two sides of a middle position of a side of the partition 13, where the middle position is matched with the fixing slot 14, and a person skilled in the art can adjust the height positions of the first protrusion 131 and the second protrusion 132 according to actual needs, the first protrusion 131 extends horizontally toward the left side, and the second protrusion 132 extends horizontally toward the right side. The first protrusion 131 and the second protrusion 132 respectively abut against two inner walls of the fixing groove 14. For example, the first protrusion 131 located on the left side is attached to the left inner wall of the fixing groove 14, and the second protrusion 132 located on the right side is attached to the right inner wall of the fixing groove 14. The first bulge 131 and the second bulge 132 are respectively arranged on two sides to form connection fixation between the partition plate 13 and the fixed groove 14, and compared with the prior art, the contact area between the partition plate 13 and the fixed groove 14 is increased, the connection effect is better realized, and the first bulge 131 and the second bulge 132 are not easy to break.

Specifically, the length of the second protrusion 132 is greater than the length of the first protrusion 131. The lengths of the two protrusions are not uniform, and the fixing strength is improved, so that the contact area between the partition 13 and the fixing groove 14 is increased. In addition, the length of the first protrusion 131 may be identical to the length of the first protrusion 131.

Specifically, the length of the second protrusion 132 is at least twice the length of the first protrusion 131. Therefore, the partition 13 forms an L-shaped structure, and the contact area between the second protrusion 132 and the fixing groove 14 is further increased, so that the fixing is more firm and stable.

Specifically, as shown in fig. 1 to 3 and 5, the top surfaces of the first and second protrusions 131 and 132 do not exceed the top surface of the fixing groove 14. Here, the first protrusion 131 and the second protrusion 132 have the same height, and the first protrusion 131 and the second protrusion 132 may be inserted into the fixing groove 14 such that the top surfaces of the first protrusion 131 and the second protrusion 132 are lower than the top surface of the fixing groove 14; here, the top surfaces of the first and second protrusions 131 and 132 may be flush with the top surface of the fixing groove 14. This structural arrangement, mainly in cooperation with the arc-isolating cover, forms a further fixing effect of the partition 13.

Specifically, as shown in fig. 1-3, the electrical unit 12 includes a base 15, and the fixing groove 14 is formed by splicing two adjacent bases 15. The two adjacent bases 15 are spliced, so that the fixed groove 14 is more convenient to process. Here, the bases 15 of two adjacent electrical units 12 are attached to form a mating effect. For example, the base 15 on the left side is provided with a portion of the fixing groove 14, and the portion is opened to the right side and to the upper side, and the base 15 on the right side is provided with another portion of the fixing groove 14, and the portion is opened to the left side and to the upper side, so that the fixing groove 14 is formed by splicing when the two bases 15 are engaged.

The gap 122 is located between two adjacent arc-isolating covers 17, and in short, the right side surface of the arc-isolating cover 17 located at the left side is not attached to the left side surface of the arc-isolating cover 17 located at the right side, and a gap 122 is formed between the two, so that the width and the length of the gap 122 can be adjusted. The arc-isolating cover 17 is provided with a limiting part 171, wherein the limiting part 171 is positioned on the bottom surface of the arc-isolating cover 17, and the limiting part 171 is positioned above the fixing groove 14. The spacing portion 171 is arranged, when the partition 13 is connected and fixed with the fixing groove 14, an effect of spacing and fixing is formed by the arc-isolating cover 17, and the partition 13 is prevented from falling off. Specifically, the left and right sides of one arc-shielding cover 17 are provided with limiting portions 171, for example, one fixing groove 14 corresponds to two arc-shielding covers 17 respectively, the limiting portion 171 of the arc-shielding cover 17 located at the left side is located above the first protrusion 131, and the limiting portion 171 of the arc-shielding cover 17 located at the right side is located above the second protrusion 132, so that limiting of the partition 13 in the vertical direction is achieved.

Specifically, as shown in fig. 1-4, the arc shield 17 is provided with a guide surface 172, and the guide surface 172 communicates with the gap 122. The front and rear ends of the left and right side surfaces of the arc-isolation cover 17 are provided with guide surfaces 172. The provision of the guide surface 172 creates an arc guiding effect, and even if an arc enters the gap 122, an isolating effect can be created by the extension 133.
