[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
[0030] Reference Figure 1-Figure 4 The utility model provides a US standard socket protection door interlocking structure, including a base 1, a first protection door 2, a first elastic reset member 3, a second protection door 4 and a second elastic reset member 5. The base 1 is provided with a ground wire jack 101, a neutral wire jack 102 and a live wire jack 103. The live wire jack 103 includes a vertical hole 1031 and a horizontal hole 1032 connected to the side of the vertical hole 1031. The vertical hole 1031 and the horizontal hole 1032 are T-shaped structures rotated 90 degrees counterclockwise, which can be used for LN two vertical plugs and LN vertical and horizontal plugs. The tail of the first protection door 2 is slidably plugged in with the second protection door 4. The second protection door 4 cannot be opened normally without opening the first protection door 2, which plays a role of interlocking protection.
[0031] Among them, Figure 1As shown, the first protection door 2 is a rectangular frame structure, the left side frame of the first protection door 2 covers the neutral line jack 102, and the right side frame of the first protection door 2 covers the vertical hole 1031. A first stopper 6 is provided on the base 1 and extends into the frame of the first protection door 2, and a first elastic reset member 3 is provided between the right side of the first stopper 6 and the right side frame of the first protection door 2, and the first elastic reset member 3 is a spring.
[0032] like Figure 3 As shown, a first inclined surface 201 is provided on the left side frame of the first protection door 2, and a second inclined surface 202 is provided on the right side frame, and an arc-shaped support block 7 is provided on the base 1. The first protection door 2 abuts against the arc-shaped support block 7, and the arc-shaped support block 7 plays the role of a lever support. The first protection door 2 cannot stably translate on the arc-shaped support block 7. A boss 8 is provided on the left side base of the left side frame of the first protection door 2. When a single plug metal insert or other object is used to press the first inclined surface 201 or the second inclined surface 202, the first protection door 2 can move to the left. However, since only one side of the two ends of the arc-shaped support block 7 is subjected to pressure, the first protection door 2 cannot remain stable on the arc-shaped support block 7 during the leftward movement. When the first protection door 2 passes the center, the left end becomes heavier and tilts downward, so that the left side frame of the first protection door 2 abuts against the side wall of the boss 8. Due to the obstruction of the boss 8, the neutral line socket 102 and the live line socket 103 below cannot be opened, which plays the role of single-hole safety protection. Only by using the LN two vertical plugs and pressing the first bevel 201 and the second bevel 202 at both ends of the plug at the same time can the first protective door 2 move to the left, so that the left and right ends of the first protective door 2 are subjected to pressure during the leftward movement, so that it can maintain stable translation on the arc-shaped support block 7. Under the joint action of the two ends of the LN two vertical plugs, the left side frame of the first protective door 2 passes over the top of the boss 8, so that the neutral wire socket 102 and the live wire socket 103 under the first protective door 2 are opened.
[0033] The second protection door 4 is also a rectangular frame structure, and the lower side frame of the second protection door 4 covers the horizontal hole 1032. A second stopper 9 is provided on the base 1 and extends into the frame of the second protection door 4. A second elastic reset member 5 is provided between the lower side of the second stopper 9 and the lower side frame of the second protection door 4. The second elastic reset member 5 is a spring. A third inclined surface 401 is provided on the lower side frame of the second protection door 4. The second protection door 4 can be moved upward by pressing the third inclined surface 401 with the horizontal metal insert of the LN vertical and horizontal plug.
[0034] Since the first protective door 2 needs to press the first bevel 201 and the second bevel 202 at the same time to move the first protective door 2 to the left to open the neutral wire socket 102 and the live wire socket 103, and the vertical metal plug of the LN vertical and horizontal plug presses the first bevel 201, the lower side frame of the second protective door 4 is designed to abut against the right side frame of the first protective door 2, so that the horizontal metal plug of the LN vertical and horizontal plug can press the second bevel 202 and the third bevel 401 at the same time. While pushing the first protective door 2 to move to the left, the plug block 203 on the right side of the right side frame of the first protective door 2 slides out of the slot 402 on the left side frame of the second protective door 4, releasing the lock and allowing the second protective door 4 to move upward.
[0035] Reference Figure 5 The utility model provides a U.S. standard socket, including a cover 10 and the above-mentioned U.S. standard socket protection door interlocking structure, the cover 10 is arranged on the top of the base 1 to play a protective role, the cover 10 is provided with a first socket 1001, a second socket 1002 and a third socket 1003 corresponding to the ground socket 101, the neutral socket 102 and the live socket 103 respectively, the third socket 1003 includes a vertical socket 10031 and a horizontal socket 10032 corresponding to the vertical hole 1031 and the horizontal hole 1032 respectively, the horizontal socket 10032 is connected to the side of the vertical socket 10031, because the horizontal socket 10032 is connected to the vertical socket 10031, so when the LN vertical and horizontal plug is used, its horizontal metal insert can pass through the horizontal socket 10032 and press the second inclined surface 202 and the third inclined surface 401 at the same time.
[0036] Working principle:
[0037] When using the LN two-vertical plug, the two vertical metal plugs at the front end of the plug pass through the second socket 1002 and the vertical socket 10031 respectively, and pressing the first inclined surface 201 and the second inclined surface 202 at the same time can move the first protection door 2 to the left, so that the left side frame of the first protection door 2 passes over the top of the boss 8, so that the neutral wire socket 102 and the live wire socket 103 under the first protection door 2 are opened, and the two vertical metal plugs at the front end of the plug are inserted into the neutral wire socket 102 and the vertical hole 1031 to connect the circuit, and at the same time, the ground wire metal plug also passes through the first socket 1001 and is directly inserted into the ground wire socket 101.
[0038] When using the LN vertical and horizontal plug, the vertical metal plug at the front end of the plug passes through the second socket 1002 and presses the first inclined surface 201, and the horizontal metal plug at the front end of the plug passes through the horizontal socket 10032 and presses the second inclined surface 202 and the third inclined surface 401 at the same time. While pushing the first protection door 2 to move to the left, the second protection door 4 moves upward, so that the vertical metal plug at the front end of the plug is inserted into the neutral socket 102, and the horizontal metal plug is inserted into the horizontal hole 1032. At the same time, the ground wire metal plug also passes through the first socket 1001 and is directly inserted into the ground wire socket 101.
[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
