[0031] like Figures 1 to 3As shown, according to an embodiment of the present invention, the present invention provides a multifunctional socket box suitable for a test site of a space launch site, comprising a box body 1 and a plurality of modular sockets 2 and an isolating switch 3 fixed in the box body 1;

[0032] The plurality of modular sockets 2 include at least five 220V 10A sockets, four 220V 16A sockets, one 380V 16A socket and one 380V 25A socket;

[0033] Any modular socket 2 is detachably connected to the box 1;

[0034] The box body 1 is provided with a box door cover plate 11 , and the box door cover plate 11 supports a rod 12 .

[0035] By configuring sockets of various specifications in the same socket box, 5 220V 10A sockets and 4 220V 16A sockets are evenly distributed on three phases to meet the three-phase load balance, 1 380V 16A socket and 1 380V 25A socket meet the power supply requirements of three-phase equipment, and all types of single-phase and three-phase equipment can meet the power supply interface requirements. The modular socket 2 is detachably connected to the box 1, which is easy to assemble, simple to replace, and firmly plugged in; the leakage protection is cancelled at the power inlet, and only the isolation switch 3 or circuit breaker protection is used, which is conducive to ensuring continuous power supply to the equipment in the test site; the box door cover 11 is equipped with a support rod 12, which can protect the plug connection and improve the power supply reliability.

[0036] In some embodiments of the present invention, the box body 1 is a rectangular parallelepiped structure, and further includes a back plate for fixing to a wall, and a slide rail 13 is provided on the surface of the back plate located on the inner side of the box body 1;

[0037] Any modular socket 2 is provided with a slide groove adapted to the slide rail 13 .

[0038] The modular socket 2 and the box body 1 are assembled by sliding, which is convenient for assembling the multifunctional socket box and plugging and unplugging the socket. The box body 1 is designed as a rectangular parallelepiped structure, which is also easy to produce and assemble. The rectangular parallelepiped box body 1 includes six faces, one of which is a back panel, which is usually fixedly connected to the wall. The face where the back panel is fixed to the wall is located on the outside of the box body 1, and a slide rail 13 for fixing the modular socket 2 is provided on the inside, and the modular socket 2 is provided with a slide groove.

[0039] In some embodiments of the present utility model, the cross section of the slide rail 13 is a trapezoidal structure, and is fixed to the back plate by a fixing plate;

[0040] The slide rail 13 of the trapezoidal structure is inverted and fixed on the fixed plate.

[0041] In some embodiments of the present invention, the slide groove matched with the slide rail 13 is in a strip shape, the upper side of the slide groove is at a right angle to the vertical surface, and the lower side is at an acute angle to the vertical surface.

[0042] The lower side surface is at an acute angle to the vertical surface, that is, there is a fixed groove below the slide; the upper side surface of the slide is at a right angle to the vertical surface, that is, there is a movable slot above the slide, which is easy to install, more firmly connected, and more convenient to inspect and replace.

[0043] In some embodiments of the present invention, the support rod 12 is a telescopic rod, one end of which is fixed to the door cover 11 and the other end is hinged to the side panel of the box body 1 .

[0045] Conventional socket boxes use side-opening doors. After the test equipment socket is connected, the side-opening door cannot be closed. People passing through may accidentally touch the plug and cause power outages, affecting power supply reliability and making it inconvenient to use. Therefore, the use of top-opening doors in the test site socket box can effectively avoid the above problems.

[0046] Typically, the support rods 12 are disposed at both ends of the door cover 11 , and a retractable rod is used as the support rod 12 , which makes the operation process more convenient.

[0047] The support rod 12 can also be hinged to the door cover 11. When in use, the other end is supported on the side panel of the box body 1. When no support is needed, it can be stored on the door cover 11, similar to the supporting structure of the chassis cover of a car.
