[0016] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0017] This embodiment discloses a miniaturized secondary module for an interval cabinet, as shown in Figure 1As shown in the figure, it includes a secondary module body, and the secondary module body includes a secondary module housing 1, an air switch 2, a wiring terminal 3, a cable waterproof joint 4, a grounding pile head 5, a terminal compartment A61, and a terminal compartment B71. There is a cavity A6 at the lower left of the top surface of the secondary module housing. The terminal compartment A61 can be arranged in the cavity A6. The terminal compartment A61 is movably connected to the secondary module housing 1, and the terminal compartment A61 can rotate relative to the secondary module housing 1 within a certain angle. The grounding pile head 5 is arranged above the cavity A6, and the cable waterproof joint 4 is closely arranged above the grounding pile head 5. There is a cavity B7 on the right side of the cable waterproof joint 4. The terminal compartment B71 is arranged in the cavity B7. The terminal compartment B71 is movably connected to the secondary module housing 1, and the terminal compartment B71 can rotate relative to the secondary module housing 1 within a certain angle. The wiring terminal 3 is close to the right end of the cavity A6, and the air switch 2 is closely arranged at the lower right corner of the secondary module housing next to the wiring terminal 3. By arranging the cavity A6 and the cavity B7, the internal free space is reduced, and the volume is reduced to improve the space utilization rate of the present invention. The components that are prone to heat generation are placed in a staggered manner to reduce heat concentration. The required components are reasonably arranged according to the required space as described above, and are integrated as much as possible while meeting the use of functional components. The components that are prone to heat generation are close to the edge heat dissipation components to reduce heat accumulation and extend the service life. Without affecting the function, the volume of the present invention is reduced, making the structure of the present invention compact and suitable for the use occasions that require miniaturization.

[0018] As Figure 2 shown in the figure, at the movable connection between the terminal compartment A61 and the terminal compartment B71 and the secondary module housing 1, there is a friction damping limiting device 8. The friction damping limiting device 8 includes a cavity C81 arranged in the secondary module housing, and pin blocks at both ends of the terminal compartment A61 and the terminal compartment B71. The pin block 82 is provided with a pin block protrusion 821. The pin block 82 is arranged in the cavity C81, and the pin block protrusion 821 can move in the cavity C81. By designing the space in the cavity C for the pin block protrusion 821 to move, the rotation of the pin block 82 is restricted. The internal wiring of the terminal compartment A61 and the terminal compartment B71 is a flexible wire with a certain margin. Therefore, the terminal compartment A61 and the terminal compartment B71 can rotate up and down with damping within the range set by the limiting device 8. When a wiring plug needs to be inserted into the terminal compartment, the terminal compartment can rotate relative to the secondary module housing, so that the plug can be inserted from a certain angle range, rather than only being inserted vertically. The operation process is more convenient and more suitable for working in a narrow space. When working in a narrow space, the space for inserting the plug is relatively limited. When inserting the plug vertically, the plug wiring is likely to be bent to a large extent, and it is subjected to a large bending stress, reducing the service life of the plug wiring. The present invention can rotate the terminal compartment, which not only facilitates the insertion of the plug and improves work efficiency, but also can reduce the bending degree of the plug wiring, reduce the internal bending stress of the wiring, and extend the service life of the plug wiring.

[0019] Further improvement, a heat dissipation protrusion 11 is provided on the side of the secondary module shell. The heat dissipation protrusion is a uniformly arranged rectangular protrusion. The heat dissipation area is increased by increasing the side protrusions, and a higher heat dissipation efficiency is obtained without changing the heat dissipation environment. The heat dissipation efficiency is improved without significantly increasing the cost and volume, so that while miniaturization and centralization are achieved, the impression of heat concentration is reduced and the service life is increased.

[0020] Further improvement, the terminal compartment B is a 20-core terminal compartment, of which the 14P terminal is a spring terminal with ear screws, and the 6P current terminal is a welded plate spring terminal. The plug is fastened by the spring terminal, making the connection reliable, not only eliminating the risk of the terminal falling off, but also eliminating the need to use other buckles when wiring, reducing its own volume while improving wiring efficiency.

[0021] Further improvement, the grounding post 5, terminal compartment A61, and terminal compartment B71 are respectively connected to the integrated circuit board arranged in the secondary module housing 1 through cables, and the mutual interference is low; the integrated circuit board adopts the line board opening process. The opening process can be used to create shielding grooves or install grounding elements, which helps to reduce electromagnetic interference and improve the electromagnetic compatibility of circuit boards. It can realize more complex circuit designs in a limited space and help miniaturization and centralization; the opening process helps to form an effective heat dissipation channel, which helps to conduct heat away from the hot spot area on the circuit board, thereby reducing the overall temperature and improving stability. To ensure its insulation strength, the impact pressure resistance can adapt to extreme environments, such as high altitudes.

[0022] For further improvement, the internal circuit of the secondary module body adopts the bare copper zinc stacking process to improve the current carrying capacity, which can reduce the material cost without sacrificing performance; the three-proof paint is sprayed to improve the sealing and extend the service life.

[0023] For further improvement, the air switch 2 is provided with a waterproof cover, which can effectively prevent moisture from entering the interior of the air switch 2, effectively prevent condensation, and avoid short circuit or leakage accidents. At the same time, the waterproof cover can also reduce malfunctions caused by the accumulation of dust and other impurities. Reduce safety risks caused by misoperation. In some special environments, such as chemical plants or seaside places with strong corrosiveness, the waterproof cover can protect the air switch 2 from corrosive gases or liquids, improve adaptability, and extend service life.

[0024] For further improvement, the secondary module housing 1 adopts a rounded corner design, which can reduce stress concentration at the corners of the housing and improve the durability and reliability of the structure; under the action of mechanical impact or thermal stress, the rounded corners can disperse these stresses and enhance the mechanical strength of the housing; and the rounded corner design helps to improve air flow and help improve heat dissipation efficiency.

[0025] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
