[0030] See also Figures 1 to 6The present invention provides a technical solution: a self-protecting new energy high-voltage and household five-core charging socket, comprising a socket body 3; a first safety door 4, a second safety door 5, a micro switch 6 and a spring 7 are arranged on the socket body 3, the first safety door 4 and the second safety door 5 are relatively distributed, the first safety door 4 includes a first inclined surface 41 and a first clamping column 42, the first inclined surface 41 facilitates the connection between the two-core plug terminal and the wiring terminal, the second safety door 5 includes a second inclined surface 51 and a second clamping column 52, the second inclined surface 51 facilitates the connection between the three-core plug terminal and the wiring terminal, the first clamping column 42 and the second clamping column 52 are relatively distributed, one end of the spring 7 is connected to the first clamping column 42, and the other end is connected to the second clamping column 52; a micro switch 6 is arranged on the outside of the first safety door 4, and a micro switch 6 is also arranged on the outside of the second safety door 5, the micro switch 6 is connected to the relay, and the relay controls the power on and off of the wiring terminal.

[0031] In this embodiment, refer to Figure 3 When using a two-core plug, insert the two-core plug into the two-core jack on the socket housing 2, and then refer to Figure 4 After the insert of the two-core plug enters the two-core jack, it will contact the first inclined surface 41 in the first safety door 4. Under the action of the insert of the two-core plug moving downward, the first safety door 4 will move to the left. When the first safety door 4 contacts the micro switch 6 located on the left side of the first safety door 4, the micro switch 6 starts the relay after being energized, and the relay starts to control the socket to be energized. At this time, the insert of the two-core plug forms a path with the wiring terminal. When the insert of the two-core plug is pulled out, the micro switch 6 is de-energized to cut off the power to the connected relay, so that the relay controls the wiring terminal to be de-energized. In this process, the wiring terminal will not be energized when the insert is inserted and pulled out, thereby avoiding the problem of electric sparks generated by the contact between the insert and the terminal during the plug and socket insertion and removal process;

[0032] See also Figure 3 When using a three-core plug, insert the core of the three-core plug into the three-core jack on the socket housing 2, and then refer to Figure 4 After the core of the three-core plug enters the three-core socket, it will contact the second inclined surface 51 in the second safety door 5. Under the action of the downward movement of the core of the three-core plug, the second safety door 5 will move to the right. When the second safety door 5 contacts the micro switch 6 located on the right side of the second safety door 5, the micro switch 6 will start the relay after being energized, and the relay will start to control the socket to be energized. At this time, the core of the three-core plug is inserted to form a path with the wiring terminal. When the core of the three-core plug is pulled out, the micro switch 6 will cut off the power to the connected relay, so that the relay controls the wiring terminal to cut off the power. In this process, the wiring terminal will not be energized when the core is inserted and pulled out, thereby avoiding the problem of electric sparks generated by the contact between the core and the terminal during the plug-in and plug-out process of the plug and the socket;

[0033] The restoring force of the spring 7 can drive the first safety door 4 and the second safety door 5 to reset when the plug is pulled out.

[0034] For further information, see Figure 1 and Figure 2 A socket shell 2 is disposed outside the socket body 3, and a flip cover 1 is hingedly disposed on the socket shell 2.

[0035] In this embodiment, the flip cover 1 is used to protect the terminals in the socket housing 2 to prevent dust accumulation and oxidation that affect use; the flip cover 1 is opened when in use and closed when not in use.

[0036] For further information, see Figure 1 The connection terminals include an L terminal 8, an N terminal 9 and a ground terminal 10.

[0037] In this embodiment, the connection terminal includes an L-pole terminal 8, an N-pole terminal 9 and a ground terminal 10, wherein the ground terminal 10 is used to protect the circuit.

[0038] For further information, see Figure 1 , the connection terminal is electrically connected to the PCB board 12.

[0039] In this embodiment, the PCB board 12 provides a stable electrical connection for the electronic components and also plays an important role in signal transmission and heat dissipation.

[0040] For further information, see Figure 1 , the connection terminal is electrically connected to the three-core socket terminal 13.

[0041] In this embodiment, the wiring terminal is electrically connected to the three-core socket terminal 13, and the wiring terminal includes an L terminal 8, an N terminal 9 and a ground terminal 10. The wiring terminal is a plug-in structure, which is convenient for connecting the core and the terminal, and also makes the plug and the socket tightly connected.

[0042] For further information, see Figure 1 and Figure 2 A socket fixing cover plate 14 is provided outside the three-core socket terminal 13 .

[0043] In this embodiment, the socket fixing cover plate 14 is used to protect the internal wiring terminals, the PCB board 12 and the three-core socket terminals 13 .

[0044] For further information, see Figure 2 , the PCB board 12 is electrically connected to the indicator light 11.

[0045] In this embodiment, the indicator light 11 is lit to indicate that the power is on, and the indicator light 11 is turned off to indicate that the power is off.

[0046] The working principle and use process of the present invention are as follows: when a two-core plug is used, the plug of the two-core plug is inserted into the two-core jack on the socket housing 2. After the plug of the two-core plug enters the two-core jack, it will contact the first inclined surface 41 in the first safety door 4. Under the action of the downward movement of the plug of the two-core plug, the first safety door 4 will move to the left. When the first safety door 4 contacts the micro switch 6 located on the left side of the first safety door 4, the micro switch 6 starts the relay after being energized, and the relay starts to control the socket to be energized. At this time, the plug of the two-core plug is inserted to form a passage with the wiring terminal. When the plug of the two-core plug is pulled out, the micro switch 6 is powered off to power off the connected relay, so that the relay controls the wiring terminal to be powered off. In this process, the wiring terminal will not be energized when the plug is inserted and pulled out, thereby avoiding the problem of electric sparks generated by the contact between the plug and the terminal during the plug-in and plug-out process of the plug and the socket;

[0047] When a three-core plug is used, the plug of the three-core plug is inserted into the three-core jack on the socket housing 2. After the plug of the three-core plug enters the three-core jack, it will contact the second inclined surface 51 in the second safety door 5. Under the action of the downward movement of the plug of the three-core plug, the second safety door 5 will move to the right. When the second safety door 5 contacts the micro switch 6 located on the right side of the second safety door 5, the micro switch 6 will start the relay after being energized, and the relay will start to control the socket to be energized. At this time, the plug of the three-core plug is inserted to form a passage with the wiring terminal. When the plug of the three-core plug is pulled out, the micro switch 6 will cut off the power to the connected relay, thereby controlling the wiring terminal to cut off the power. In this process, the wiring terminal will not be energized when the plug is inserted and after it is pulled out, thereby avoiding the problem of electric sparks generated by the contact between the plug and the terminal during the plug and socket insertion and removal.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
