The isolation support plate 30 has several through holes 31 corresponding to the positions of all the plug holes 21. The protective door mechanism 40 is installed inside a protective compartment 33.

[0030] The plug-in compartment 20 is a conventional plug-in module, and its specific structure will not be described in detail here. The protective door mechanism 40 is also a common structure. Both of the above can be referred to the specific structure in patent CN210182651U - Safety door structure and plug-in device for plug-in device or CN112413443A - Waterproof power strip. They will not be described in detail here.

[0031] The isolation support plate 30 can be fastened to the housing 10, the insertion compartment 20, or both ends of the plate can be fastened to the housing 10 and the insertion compartment 20 respectively. In some possible embodiments, to facilitate installation and fixation and prevent loosening between the insertion compartment 20 and the isolation support plate 30, at least one fastening groove 23 is provided on the outer wall of the insertion compartment 20, and the isolation support plate 30 is provided with buckles 35 that are adapted to the positions of all the fastening grooves 23. The buckles 35 are fastened into the fastening grooves 23 to achieve the fastening of the isolation support plate 30 onto the insertion compartment 20. Furthermore, to increase the stability of the fastening, two fastening grooves 23 are provided on each of the opposite outer walls of the insertion compartment 20, and the position and number of buckles correspond to the fastening grooves 23. The stability of the fastening is improved by fastening at four locations. Similarly, in other embodiments, when the isolation support plate 30 is fastened to the housing 10, the fastening grooves can also be provided on the housing 10.

[0032] In some possible embodiments, the isolation support plate 30 has a circumferentially extending protective edge 32 on the side away from the insertion compartment 20. The opening edge of the protective edge 32 abuts against the inner wall of the housing 10 and forms a protective compartment 33, so that the isolation support plate 30 can fit tightly against the housing 10, thereby ensuring the sealing of the entire insertion device.

[0033] In some possible embodiments, to facilitate installation and ensure tightness during subsequent installation, the housing 10 is provided with a snap-fit ​​groove 12 that mates with one end of the opening of the protective edge 32, and the protective edge 32 is inserted into the snap-fit ​​groove 12. The structural design of the snap-fit ​​groove 12, in conjunction with the protective edge 32, can ensure the tightness and sealing of the protective compartment 33, and ensure the sealing of the protective door mechanism 40 during subsequent use.

[0034] In some possible embodiments, to facilitate the installation and fixing of the insert 20 and the isolation support plate 30, a plurality of mounting ears 25 are provided on the periphery of the insert 20. The mounting ears 25 are detachably connected to the housing 10. Further, the mounting ears 25 can be snapped onto the housing 10 or installed on the housing 10 via threaded connectors. Even further, each mounting ear 25 has a mounting hole 26, and a mounting post 13 adapted to the mounting hole 26 is provided inside the housing 10. The mounting ears 25 are fixed to the mounting post 13 with screws to restrict and fix the isolation support plate 30 between the insert 20 and the inner wall of the housing 10. This structural design, by fixing the insert 20 and the isolation support plate 30 simultaneously, can effectively adapt to the operation of the protective door mechanism 40.

[0035] Reference Figures 2 to 3 As shown, to facilitate the installation of the isolation support plate 30 on the insert 20, a mounting ring 34 is provided on the periphery of the side of the isolation support plate 30 away from the protective edge 32. The mounting ring 34 is inserted into or sleeved on the end of the insert 20. In some embodiments, the mounting ring 34 is sleeved on the end of the insert 20 where the insertion hole 21 is provided. This structure can effectively limit and relatively fix the position between the insert 20 and the isolation support plate 30, which is beneficial to the adaptation between the insertion hole 21 and the through hole 31.

[0036] In some possible embodiments, to facilitate a more secure connection between the insert 20 and the isolation support plate 30, a raised edge 24 is provided on the periphery of the side of the insert 20 closest to the isolation support plate 30, and a boss 36 is provided on the side of the isolation support plate 30 away from the protective edge 32. The boss 36 fits against the end face of the insert 20 with the insertion hole 21. This design ensures that there are no holes between the corresponding sides of the isolation support plate 30 and the insert 20, which helps to maintain continuity between the insertion hole 21 and the through hole 31, facilitating the smooth insertion of external electrical plugs later. Furthermore, a locking annular groove 37 for accommodating the raised edge 24 is formed between the boss 36 and the mounting ring 34. This design helps the raised edge 24 to be securely inserted into the isolation support plate 30, ensuring tightness in subsequent installation.

[0037] This safety power supply device with a fixed compartment structure incorporates an isolation support plate 30 between the housing 10 and the insertion compartment 20. This forms a protective compartment 33 for installing the protective door mechanism 40. The isolation support plate 30 is not integrally formed with the housing 10 or the insertion compartment 20, facilitating modular manufacturing and component replacement, thus reducing maintenance costs. Furthermore, the isolation support plate 30 and the insertion compartment 20 are interlocked, and the isolation support plate 30 is securely fixed between the insertion compartment 20 and the inner wall of the housing 10. This structural installation effectively ensures the stability of the isolation support plate 30, preventing loosening due to the movement of the protective door mechanism 40 during use, and facilitating overall assembly and disassembly. The protective compartment 33 formed between the isolation support plate 30 and the housing 10 effectively ensures the sealing of the protective door mechanism 40, thereby improving the overall sealing performance of the insertion device.
