The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.

[0031] like Figures 1 to 4 As shown, according to an embodiment of the present utility model, the present utility model provides a multifunctional explosion-proof socket box suitable for a test site of a space launch site, comprising a box body 1 and a plurality of explosion-proof sockets 2 and an isolating switch 3 fixed in the box body 1;

[0032] The plurality of explosion-proof sockets 2 include 6 220V 16A sockets evenly distributed on three phases to meet the three-phase load balance, and 1 380V 16A socket to meet the power supply requirements of three-phase equipment;

[0033] Any of the explosion-proof sockets 2 is detachably connected to the box 1;

[0034] Any of the 220V 16A sockets is a single-phase explosion-proof socket.

[0035] In some embodiments of the present invention, a socket panel is provided in the box body 1, and a plurality of explosion-proof sockets 2 are fixed on the socket panel.

[0036] By configuring sockets of various specifications in the same socket box, including 6 220V 16A sockets and 1 380V 16A socket, the 220V 16A socket is a single-phase explosion-proof socket, which meets the explosion-proof power supply interface requirements of different equipment, improves power supply reliability, and ensures safe and reliable wiring. It meets the explosion-proof performance requirements and ensures the safety of personnel and equipment. It has been widely used in launch sites;

[0037] Furthermore, leakage protection is eliminated at the power supply inlet, and only an isolating switch or circuit breaker is used for protection, which is conducive to ensuring continuous power supply to the equipment in the test site.

[0038] In some embodiments of the present invention, the six 220V 16A sockets are arranged in groups of two.

[0039] In some embodiments of the present invention, the six 220V 16A sockets, the one 380V 16A socket, and the isolating switch 3 are arranged in a four-square format.

[0040] In some embodiments of the utility model, the isolating switch is arranged at the upper left position of the four-square grid, the 380V 16A socket is arranged at the lower left position of the four-square grid, the two 220V 16A sockets are arranged at the upper right position of the four-square grid, and the remaining four 220V 16A sockets are arranged at the lower right position of the four-square grid.

[0041] Through the above arrangement, the multifunctional explosion-proof socket box of the utility model has a simple structure, the positions of each socket are more reasonable, and it is convenient for maintenance, which can reduce the workload of maintenance.

[0042] In some embodiments of the utility model, any of the 220V 16A sockets or the 380V 16A sockets are equipped with a mechanical lock ring 4, and a mechanical interlock is provided between the socket and the plug. After the plug is inserted, the mechanical lock is rotated to ensure that the plug and the socket are reliably connected and do not fall off. When the plug needs to be unplugged after use, the mechanical lock is rotated first to disconnect the plug from the socket, and then the plug is unplugged, which effectively prevents live plugging.

[0043] In some embodiments of the present utility model, the multifunctional explosion-proof socket box is a rectangular parallelepiped structure with a length of 450 to 800 mm, a width of 100 to 300 mm, and a height of 450 to 850 mm.

[0044] In some embodiments of the present invention, any of the explosion-proof sockets 2 comprises a socket sleeve 21, a socket terminal 22 and a V-shaped movable part 23, wherein the socket sleeve 21 and the socket terminal 22 are fixed parts.

[0045] In some embodiments of the present invention, the V-shaped movable member 23 includes planar segments 231 on both sides and an arc segment 232 in the middle.

[0046] In some embodiments of the present invention, the V-shaped movable member 23 further includes a spring 233 , and the spring 233 is disposed between the two planar sections 231 .

[0047] During the use of the multifunctional explosion-proof socket box, the explosion-proof plug device is composed of two major components, the plug and the socket. The inside of the plug and the socket are composed of movable parts and fixed parts. When the plug and the socket are plugged in, the plug pin cooperates with the socket socket, and the plug closing pin cooperates with the socket closing slot. At this time, the plug shell is rotated, and the plug shell rotates relative to the socket. The plug inner core closing pin drives the internal movable surface of the socket to rotate, so that the electrical connectors inside the socket are separated or connected, thereby achieving the purpose of separation and closing. Figure 3 and Figure 4As shown, when in the open position, the socket sleeve 21 and the socket terminal 22 are isolated and have no electrical connection. When the plug housing is rotated, the V-shaped movable part 23 is driven to rotate clockwise through the plug closing pin → socket closing slot → socket internal movable surface, so that the V-shaped movable part 23 is inserted between the socket sleeve 21 and the socket terminal 22, thereby achieving the purpose of electrical connection between the two. The spring 233 clamping structure is adopted, and the plug can be fastened and clamped after insertion to ensure good contact between the plug and the socket, avoiding accidental power outage or heating caused by virtual connection of the plug. In addition, the plug matched with the explosion-proof socket box of this application is equipped with a padlock, which can be locked when not in use, effectively preventing others from operating it incorrectly and improving safety.
