In the manufacturing process, the application of injection molding technology makes the production efficiency of middle plate get the remarkable promotion, and compared with the middle plate made of complete metal material, the material cost can also be reduced. The metal layer 2 in the design is galvanized iron, stainless steel or the like, and the plastic layer 3 is plastic material.

[0022] Further, the metal layer 2 has an inner body portion 4 and an inner connecting portion 5, the inner body portion 4 is provided with a central mounting hole 6, the inner connecting portion 5 is formed by the edge portion of the inner body portion 4 close to the central mounting hole 6 protruding towards the inner body portion 4, and the plastic layer 3 is provided with an outer body portion 7 and an outer connecting portion 8 corresponding to the inner body portion 4 and the inner connecting portion 5. Specifically, in this embodiment, the outer surface of the inner body portion 4 is tightly attached to the outer body portion 7 of the plastic layer 3, and the outer surface of the inner connecting portion 5 is tightly attached to the outer connecting portion 8 of the plastic layer 3. This design makes the metal layer 2 and the plastic layer 3 have good bonding force, thereby ensuring the structural stability and durability of the middle plate as a whole. At the same time, the setting of the inner connecting portion 5 enhances the fixing and supporting capacity of the middle plate, so that the middle plate can withstand greater force during installation and use, improving the reliability of the product. In addition, the design of the central mounting hole 6 facilitates the connection of the middle plate and the switch box, making the installation process more convenient and fast. The size and shape of the central mounting hole 6 can be customized according to actual needs to adapt to switch boxes of different specifications, thereby improving the universality and compatibility of the middle plate.

[0023] Further, the inner body part 4 has a first inner surface 9 and a second inner surface 10, the inner connecting part 5 is protruded from the edge of the inner body part 4 close to the center mounting hole 6 towards the second inner surface 10, two symmetrical reinforcing parts 11 are protruded on the first inner surface 9, the center of the reinforcing part 11 is concave to form an inner groove part 12, an inner mounting hole 13 is opened on the inner groove part 12, the outer body part 7 is provided with an outer groove part 15 corresponding to the inner groove part 12, and an outer mounting hole 14 corresponding to the inner mounting hole 13 is opened on the outer groove part 15.
