In addition, for simplicity and clarity of understanding, only one of the components having the same structure or function is schematically illustrated or labeled in some of the drawings.

Fig. 1 is a schematic structural view of an exemplary embodiment of a support assembly of an electric outlet, and fig. 2 is an exploded structural view for explaining the support assembly shown in fig. 1. As shown in fig. 1 and 2, the support assembly of the power socket includes a housing 10 and a safety door 20. In the present exemplary embodiment, the housing 10 is formed by combining the first member 17 and the second member 18 which are detachable, whereby the assembly can be facilitated, and the first member 17 and the second member 18 are connected by, for example, a snap connection or a bolt connection, but not limited thereto.

As shown in fig. 1, the first member 17 and the second member 18 enclose a cavity 14. The second part 18 is provided with two insertion holes 15. The two receptacles 15 extend in a first direction D1 to the cavity 14 and are aligned in a second direction D2. In the present exemplary embodiment, the first direction D1 is perpendicular to the second direction D2.

The safety door 20 is disposed in the receiving cavity 14 at one side of the two insertion holes 15 in the first direction D1. The receptacle 14 may also be adapted to receive a socket assembly (not shown) of an electrical outlet, the socket assembly being located on a side of the security door 20 facing away from the receptacle 15 in the first direction D1; the plug bush subassembly is used for being connected with the power supply electricity. The safety door 20 is movable in the second direction D2 from a closed position (i.e., the position shown in fig. 1) blocking the two insertion holes 15 to an open position (i.e., the position shown in fig. 4) opening the two insertion holes 15. Specifically, as shown in fig. 2 and 3, the emergency gate 20 has two insertion holes 23 and two guide slopes 24. As shown in fig. 4, when the emergency gate 20 is located at the open position, the two insertion holes 23 correspond to the two insertion holes 15 one by one in the first direction D1, so that the blades of the plug (shown by dotted lines) can pass through the insertion holes 15 and the insertion holes 23 in the first direction D1 to contact the socket assembly of the power outlet. As shown in fig. 2 and 3, the two guide slopes 24 are located on one side of the two insertion holes 23 in the length direction L in one-to-one correspondence. The orientation of each guide ramp 24 parallel to the length direction L is opposite to the length direction L. As shown in fig. 1, when the safety door 20 is located at the closed position, the guide slope 24 can block the corresponding receptacle 15 in the first direction D1.

As shown in fig. 1, the housing 10 includes a stopper portion 12 and a locking portion 13. The stopper portion 12 is provided on the first member 17. The stop 12 is located on the side of the safety door 20 facing away from the insertion opening 15 in the first direction D1, and the projection in the first direction D1 is located between two insertion openings 15. When the safety door 20 is located at the closed position, the length direction L of the safety door 20 is the same as the second direction D2, and the stopper 12 can abut against an abutting surface 21 of the safety door 20 extending along the length direction L. Thereby, when the safety door 20 is located at the closed position, two blades (shown by dotted lines) of the plug can pass through the two insertion holes 15 along the first direction D1, and can simultaneously push against the two guide slopes 24 of the safety door 20 along the first direction D1; the safety door 20 moves to the open position shown in fig. 4 along the second direction D2 under the pressing of the two insert sheets and the stopping part 12; two blades (shown in phantom) are inserted through the insertion holes 23 to contact the socket assembly of the power outlet, thereby achieving contact conduction.

The safety door 20 can be moved from the closed position shown in fig. 1 through the locking portion 13 in the second direction D2 to the open position shown in fig. 4. As shown in fig. 5 and 6, when the longitudinal direction L of the safety door 20 is inclined with respect to the second direction D2, the locking portion 13 can abut against the safety door 20 to prevent the passage thereof. Specifically, in the present exemplary embodiment, the retaining portion 13 includes one first stopper rib 131 and one second stopper rib 132. The first limiting rib 131 is protruded from the inner wall of the second member 18 opposite to the stopper 12 in the first direction D1. The second limiting rib 132 is disposed to protrude from the inner wall of the first member 17, and is disposed opposite to the first limiting rib 131 in the first direction D1. Fig. 7 is an enlarged view of the portion iv of fig. 1, and as shown in fig. 7, a gap 133 is formed between the first stopper rib 131 and the second stopper rib 132. The width W2 of the gap 133 in the first direction D1 is substantially equal to the height H of the emergency gate 20 in the closed position in the first direction D1 to allow the emergency gate 20 to move from the closed position through the gap 133 in the second direction D2 to the open position. As shown in fig. 5 and 6, when a foreign object (shown by a dotted line) passes through one of the insertion holes 15 and abuts against the safety door 20, the safety door 20 is inclined (i.e., the length direction L is inclined with respect to the second direction D2), and the inclined safety door 20 abuts against the first limiting rib 131 or the second limiting rib 132 and cannot pass through the gap 133 to reach the open position, i.e., cannot achieve contact conduction, thereby performing the anti-single insertion function. In other exemplary embodiments, the latch 13 may be provided in other configurations.

In an exemplary embodiment, the support assembly may be provided with only the two insertion holes, and the two insertion holes correspond to the two blades of the two-plug respectively.

The stopper rib 26 extends in a direction perpendicular to the first direction D1 and the second direction D2. When the safety door 20 is in the closed position, it abuts against the housing 10 via the stopper rib 26 by the elastic member 30. Thereby facilitating smooth rotation of the emergency gate 20 when single insertion occurs.

Figure 8 shows the perspective structure of the secondary member 18 and the safety door 20. As shown in fig. 8, in the exemplary embodiment, the housing 10 is formed with a stopper groove 11 extending in the first direction D1. As shown in fig. 1, the safety door 20 is inserted into the stopper groove 11.
