[0025] The embodiments of the utility model are further described below in conjunction with the accompanying drawings.
[0026] As shown in the figure, a European socket is a socket of European specifications, which includes a shell 1, a conductive socket 2, and a grounding bracket 6.
[0027] The shell 1 includes a lower base 11 and an upper base 12 which are connected to each other. One end of the lower base 11 is provided with two wiring terminals 3 for connecting the neutral wire and the live wire, and the other end is provided with a grounding terminal 8 for connecting the grounding wire; a circular slot 121 which is recessed downward is formed on the upper base 12, and two sockets 122 are formed at the bottom of the circular slot 121.
[0028] The conductive socket 2 is installed in the housing 1, one end of which is connected to the terminal 3, and the other end forms a socket structure and corresponds to the socket 122. After the power plug is inserted into the circular slot 121, its two pins can pass through the socket 122 and connect with the conductive socket 2, thereby forming an electrical connection.
[0029] The grounding bracket 6 is arranged in the shell 1 and is connected to the grounding terminal 8 through the grounding plate 9. The grounding bracket 6 is an overall U-shaped structure, and its two bracket arms extend upward into the circular slot 121. After the power plug is inserted into the circular slot 121, it can be grounded to the grounding bracket 6 to improve the safety performance of electricity use.
[0030] The housing 1 is further provided with a fixing plate 7 , a protection door 4 , and an elastic member 5 .
[0031] A connecting shaft 71 connected to the lower base 11 is integrally formed at the center of the lower end of the fixing plate 7, and a limiting groove 72 adapted to the grounding bracket 6 is formed on the upper end surface. The fixing plate 7 can form a circumferential limiting fit with the grounding bracket 6 through the limiting groove 72. A through hole 73 corresponding to the socket 122 is also formed on the fixing plate 7, and a clamping platform 74 is formed at the lower end edge of the fixing plate 7.
[0032] The protection door 4 includes a connecting plate 41 and baffles 42 formed at both ends of the connecting plate 41, a positioning column 412 and a center hole 411 extending from top to bottom are formed in the middle, a guide slope 421 is formed on the baffle 42, and the protection door 4 is rotatably matched with the connecting shaft 71 of the fixing plate 7 through the center hole 411. The protection door 4 has a first position in which the guide slope 421 blocks the through hole 73 and a second position in which the through hole 73 is exposed.
[0033] The elastic member 5 is a torsion spring, which is sleeved on the positioning column 412 , with one torsion foot of the elastic member 5 abutting against the clamping table 74 , and the other torsion foot abutting against one of the baffles 42 .
[0034] When there is no plug in the socket, the protective door 4 is in the first position under the action of the elastic member 5, and its baffle 42 blocks the socket 122, thereby achieving a protective effect. When a plug is inserted into the socket, the plug pin can push the protective door 4 to rotate through the guide slope 421. The protective door 4 rotates to expose the socket 122 and compress the elastic member 5. The plug is inserted into the socket to form an electrical connection with the socket. When the plug is pulled out, the protective door 4 automatically rotates and resets under the action of the elastic member 5.
[0035] With the above solution, a protective door is provided in the shell, and the protective door is rotatably provided, which not only improves the safety protection function, but also can better adapt to the European socket. At the same time, the upper base, the grounding bracket, the fixing plate, the protective door, the lower base and other parts are limited to each other, and no additional fasteners are required to form a stable and reliable structure. The structure is simple, the assembly is convenient and quick, and the cost is lower.
