[0037] Now, a detailed description of the present invention will be made according to the accompanying drawings of the specification.

[0038] In one embodiment of the present invention, a socket system is provided, comprising a power supply system, at least one group of output springs 6, a trigger device 9 and a weak current system 7; the power supply system is used to provide power to at least one group of output springs 6; the output springs 6 are used to output power; when a plug 1 is inserted into the inner space of the output spring 6, conduction information is generated, and when the plug 1 leaves the inner space of the output spring 6, a shutdown information is generated; the trigger device 9 is used to detect the conduction information and the shutdown information, and feed the conduction information and the shutdown information back to the weak current system 7; the weak current system 7 is used to control the power supply system and the output spring 6 to conduct when receiving the conduction information, and to control the power supply system and the output spring 6 to shut down when receiving the shutdown information.

[0039] In this embodiment, the power supply system includes a neutral pole, a live pole and a ground pole.

[0040] In this embodiment, the plug 1 is provided with a plug guide, and the output spring clip 6 can be set as one or more groups according to different needs, and is used to provide one or more groups of plugs 1 with power. Each group of output spring clips 6 includes at least one live wire spring clip and one neutral wire spring clip, and a ground wire spring clip is provided when necessary. The live wire spring clip, the neutral wire spring clip and the ground wire spring clip are all provided with a accommodating space for accommodating the plug guide, and have a locking effect on the plug guide. The process of "plug 1 inserting the output spring clip 6" is: the plug guide enters the accommodating space, and the output spring clip forms a locking effect on the plug guide.

[0041] The trigger device 9 is an elastic reset switch or other means such as infrared detection. In order to save installation space and reduce costs, the trigger device 9 in this embodiment is an elastic reset switch.

[0042] In this embodiment, the socket system further includes a housing assembly, which includes a front plate 2, a middle plate 4, a mounting plate 5 and a rear cover 3; Figures 1 - 3 As shown, the front plate 2, the middle plate 4 and the mounting plate 5 are all provided with through holes for the plug of the plug 1 to pass through. The front plate 2 is buckled with the rear cover 3; the middle plate 4 is arranged in the internal space formed by the front plate 2 and the rear cover 3. The mounting plate 5 is arranged in the internal space formed by the middle plate 4 and the rear cover 3. After installation, the through holes for the plug of the plug 1 to pass through on the front plate 2, the middle plate 4 and the mounting plate 5 correspond to each other.

[0043] The weak current system 7 includes a transformer rectifier circuit and a relay; the input end of the transformer rectifier circuit is connected to the power supply system, and the output end is connected to the relay; the relay is used to drive the power supply system to conduct with the output spring 6. Figure 1 , Figure 2 and Figure 7As shown, the core components of the step-down rectifier circuit are a step-down resistor and an AC / DC converter connected in series. The step-down resistor and the AC / DC converter are determined according to the model of the relay. In this embodiment, the model of the relay is two groups of HRS3FNH-S-DC5V-A. One is used to control the conduction between the live wire terminal and the live wire elastic piece of the power supply system, and the other is used to control the conduction between the neutral wire terminal and the neutral wire elastic piece of the power supply system. The model of the AC / DC converter is PN8016. Multiple groups of step-down resistors in the weak current system 7 cooperate with the AC / DC converter to finally convert the 220V high-voltage electricity of the power supply system into 5V direct current. The trigger device 9 is normally closed. For example, Figure 13 As shown, the on-off action points of the trigger device 9 are F2-1, F2-2, F2-3, F2-4, F3-1, F3-2, F3-3, F3-4, F4-1, and F4-2.

[0044] In this embodiment, the power supply system, the output elastic piece 6, and the weak current system 7 are fixed on the mounting plate 5. The mounting plate 5 is a PCB, on which multiple groups of high-voltage wires and weak current wires are printed. The trigger device 9 and the weak current system 7 are conducted through weak current wires. The power supply system and the step-down rectifier circuit are conducted through high-voltage wires. The power supply system and the driving end of the relay are conducted through high-voltage wires. The output elastic piece 6 and the driving end of the relay are conducted through high-voltage wires.

[0045] In this embodiment, when the plug 1 is inserted into the output elastic piece 6, the trigger device 9 makes the weak current system 7 form a path, and the electromagnet in the relay starts to work. Then a path is formed between the power supply system and the output elastic piece 6. When the plug 1 leaves the output elastic piece 6, the trigger device 9 makes the weak current system 7 no longer form a path, and the electromagnet in the relay stops working. Then an open circuit is formed between the power supply system and the output elastic piece 6. At this time, the output elastic piece 6 is not charged, which increases the safety of using the socket system.

[0046] In one embodiment, as Figure 4 shown, the socket system is provided with a safety door 8. The safety door 8 is arranged between the front plate 2 and the middle plate 4 and is fixed on the middle plate 4. As Figure 5 shown, the safety door 8 includes a blocking piece 82 and a safety door spring 83 acting on the blocking piece 82; the conduction information is the opening of the safety door 8; the turn-off information is the reset of the safety door 8. The safety door 8 includes a mounting plate 81, a blocking piece 82, and a safety door spring 83; the blocking piece 82 and the safety door spring 83 are arranged inside the mounting plate 81; one side of the blocking piece 82 is provided with a safety door slider 821, and the other side is provided with a safety door trigger block 822; the side of the safety door slider 821 facing the front plate 2 is in a ramp shape, and the safety door trigger block 822 is used to trigger the trigger device 9 when the safety door 8 is opened. In the initial state, the ramp structure of the safety door slider 821 just lies at the position of the through hole of the front plate 2.

[0047] In this embodiment, as Figure 6 , Figure 7 or Figure 8 shown, the trigger device 9 includes a housing, a metal shrapnel, a conduction sheet, and a trigger button; the metal shrapnel and the conduction sheet are arranged inside the housing, a part of the trigger button contacts the metal shrapnel, and the rest part protrudes out of the housing. During the process of the plug 1 being inserted into the output shrapnel 6, when the blocking piece 82 is pushed by the plug 1 against the ramp surface of the safety door slider 821, the blocking piece 82 moves upward. When the safety door trigger block 822 reaches the trigger device 9, the trigger button is pressed, causing the metal shrapnel to deform and contact the conduction sheet, enabling the weak current system 7 to form a circuit. The electromagnet in the relay starts to work, and then a circuit is formed between the power supply system and the output shrapnel 6. When the plug 1 leaves the output shrapnel 6, the blocking piece 82 leaves, the metal shrapnel rebounds, and the trigger button returns to its original position. The weak current system 7 no longer forms a circuit, the electromagnet in the relay stops working, and then an open circuit is formed between the power supply system and the output shrapnel 6. At this time, the output shrapnel 6 is not charged, increasing the safety of using the socket system.

[0048] In one embodiment, the conduction information is the deformation of the output shrapnel 6 triggered by the plug 1; the turn-off information is the reset of the output shrapnel 6.

[0049] As Figure 9 shown, a shrapnel rear cover 61 is arranged at the bottom of the output shrapnel 6, and the trigger device 9 is arranged on the mounting plate 5. The shrapnel rear cover 61 is made of insulating polymer material. In this embodiment, the trigger block 611 is in the shape of a sheet, one end is installed on the top of the shrapnel rear cover 61, and the other end is freely arranged. It is made of elastic insulating polymer material. One side of it is in close contact with the output shrapnel 6, and the other side has a protruding part. The distance between the protruding part and the trigger button is 4 mm and they are at the same height. In this embodiment, when the plug 1 is inserted into the output shrapnel 6, the deformation of the shrapnel causes the trigger block 611 to deform. The protruding part of the trigger block 611 touches the trigger button of the elastic reset switch, causing the metal shrapnel to deform and contact the conduction sheet, enabling the weak current system 7 to form a circuit. The electromagnet in the relay starts to work, and then a circuit is formed between the power supply system and the output shrapnel 6. When the plug 1 leaves, the output shrapnel 6 returns to its original position, the trigger block 611 returns to its original position, the metal shrapnel rebounds, and the trigger button returns to its original position. The weak current system 7 no longer forms a circuit, the electromagnet in the relay stops working, and then an open circuit is formed between the power supply system and the output shrapnel 6. At this time, the output shrapnel 6 is not charged, increasing the safety of using the socket system.

[0050] In one embodiment, a shrapnel rear cover 61 is arranged outside the output shrapnel 6; the shrapnel rear cover 61 generates displacement when the plug 1 is inserted into the inner space of the output shrapnel 6 and resets when the plug 1 leaves the inner space of the output shrapnel 6; the conduction information is the displacement of the shrapnel rear cover 61; the turn-off information is the reset of the shrapnel rear cover 61.

[0051] The shrapnel rear cover 61 is arranged at the bottom of the output shrapnel 6 and is provided with a spring to make it return to its original position. One end of the spring acts on the bottom flat plate of the rear cover 3, and the other end acts on the shrapnel rear cover 61. The triggering device 9 is fixed on the bottom flat plate of the rear cover 3.

[0052] In this embodiment, when the plug 1 is inserted into the bottom of the output shrapnel 6, the end of the plug 1 pushes the shrapnel rear cover 61 to move, presses the trigger button of the reset switch, and then causes the metal shrapnel to deform and contact the conduction piece, so that the weak current system 7 forms a circuit. The electromagnet in the relay starts to work, and then a circuit is formed between the power supply system and the output shrapnel 6. When the plug 1 leaves, the shrapnel rear cover 61 returns to its original position, the metal shrapnel rebounds and the trigger button returns to its original position, the weak current system 7 no longer forms a circuit, the electromagnet in the relay stops working, and then an open circuit is formed between the power supply system and the output shrapnel 6. At this time, the output shrapnel 6 is not charged, which improves the safety of using the socket system.

[0053] In one embodiment, a triggering device is arranged in the accommodating space; the triggering device is used to generate displacement when the plug 1 is inserted into the inner space of the output shrapnel 6 and reset when the plug 1 leaves the inner space of the output shrapnel 6; the conduction information is the displacement of the triggering device; the cutoff information is the reset of the triggering device.

[0054] As Figure 10 or Figure 11 shown, the triggering device includes an end triggering slider and a slider spring. One end of the slider spring acts on the slider, and the other end acts on the side protection shell of the output shrapnel 6.

[0055] In this embodiment, when the plug 1 is inserted into the output shrapnel 6, the end of the plug guide piece pushes the end triggering slider to move, presses the trigger button of the reset switch, and then causes the metal shrapnel to deform and contact the conduction piece, so that the weak current system 7 forms a circuit. The electromagnet in the relay starts to work, and then a circuit is formed between the power supply system and the output shrapnel 6. When the plug 1 leaves, the end triggering slider returns to its original position, the metal shrapnel rebounds and the trigger button returns to its original position, the weak current system 7 no longer forms a circuit, the electromagnet in the relay stops working, and then an open circuit is formed between the power supply system and the output shrapnel 6. At this time, the output shrapnel 6 is not charged, which improves the safety of using the socket system.

[0056] In one embodiment, a shrapnel rear cover 61 is arranged at the bottom of the output shrapnel 6, and the triggering device 9 is arranged on the mounting plate 5. The shrapnel rear cover 61 is made of insulating polymer material.

[0057] In this embodiment, as Figure 12The socket system shown also includes a sheet-shaped trigger block 62, one end of which is mounted on the top of the shrapnel rear cover 61, and the other end is freely arranged. It is made of an elastic insulating polymer material. One side of it has a protruding part, and at least a part of the protruding part is arranged in the accommodation space. The distance between the trigger buttons on the other side is 4 mm and they are at the same height.

[0058] In this embodiment, when the plug 1 is inserted into the output shrapnel 6, the plug guide piece presses the protruding part of the trigger block 62, causing the trigger block 62 to deform. The other end of the trigger block 62 touches the trigger button of the elastic reset switch, which in turn causes the metal shrapnel to deform and contact the conduction piece, enabling the weak current system 7 to form a circuit. The electromagnet in the relay starts to work, and then a circuit is formed between the power supply system and the output shrapnel 6. When the plug 1 is removed, the trigger block 62 returns to its original position, the metal shrapnel rebounds and the trigger button returns to its original position, and the weak current system 7 no longer forms a circuit. The electromagnet in the relay stops working, and then an open circuit is formed between the power supply system and the output shrapnel 6. At this time, the output shrapnel 6 is not charged, increasing the safety of using the socket system.

[0059] In one embodiment, as Figure 14 or Figure 15 shown, the elastic on-off device 10 includes a moving block 101, an intermediate conductor 102, and an elastic device 103. The moving block 101 is used to conduct the power supply system and the output shrapnel 6 under the push of the plug 1. The elastic device 103 acts on the moving block 101 to reset the moving block 101. When the moving block 101 is reset, the intermediate conductor 102 stops conducting the output end of the power supply system and the output shrapnel 6.

[0060] The moving block 101 and the elastic device 103 are arranged in the accommodation space. The moving block 101 and the intermediate conductor 102 are fixedly connected. One end of the elastic device 103 acts on the output shrapnel 6, and the other end acts on the moving block 101.

[0061] The moving block 101 includes a moving block main body and a sliding rod 104. The moving block main body and the sliding rod 104 are made of insulating polymer materials. The elastic device 103 is a return spring. A sliding hole is opened at the bottom of the output shrapnel 6, and at least a part of the sliding rod 104 is located in the sliding hole. The return spring is sleeved on the sliding rod 104. The intermediate conductor 102 is fixed on the sliding rod 104. The socket system is provided with a contact piece 105 that conducts with the output end of the power supply system. The contact piece 105 is fixedly arranged relative to the output shrapnel 6 and has an L-shaped structure. The bottom is inserted into the mounting plate 5, the rod part is parallel to the sliding rod 104, and the head is arranged at a contactable position directly above the intermediate conductor 102 for contacting the contact piece 105 when the moving block 101 slides to the end. The intermediate conductor 102 is an elastic guide piece, leaving a displacement margin for the moving block 101 to achieve better electrical contact.

[0062] In this embodiment, when the plug 1 is inserted into the output elastic piece 6, the plug guide piece presses against the moving block body, and the sliding rod 104 restricts the sliding along the sliding hole. The moving block body displaces towards the bottom of the output elastic piece 6, thereby driving the intermediate conductor 102 to move towards the head of the contact piece 105. Finally, the intermediate conductor 102 contacts the head of the contact piece 105, and a path is formed between the power supply system and the output insert. The socket system starts to supply power to the plug 1. When the plug 1 leaves the output elastic piece 6, the moving block 101 and the intermediate conductor 102 return to their original positions under the action of the return spring, and an open circuit is formed between the power supply system and the output insert. At this time, the output elastic piece 6 is not charged, which increases the safety of using the socket system.

[0063] In one embodiment, as Figure 4 shown, the socket system is provided with a safety door 8. As Figure 5 shown, the safety door 8 includes a mounting plate 81, a blocking piece 82, and a safety door spring 83 acting on the blocking piece 82; the intermediate conductor 102 is fixed on the blocking piece 82 and is in sliding conduction with the output end of the power supply system, and is used for making electrical contact with the output elastic piece 6 when the blocking piece 82 is opened. The blocking piece 82 and the return spring are arranged inside the mounting plate 81; a safety door slider 821 is arranged on the side of the blocking piece 82 facing the front plate 2, and the side of the slider facing the front plate 2 is in a ramp shape. In the initial state, the ramp structure of the slider just lies at the position of the through hole of the front plate 2.

[0064] In this embodiment, a contact piece 105 is arranged on the output elastic piece 6, and the contact piece 105 is in conduction with the output elastic piece 6.

[0065] During the process of inserting the plug 1 into the output elastic piece 6, when the blocking piece 82 is pushed by the plug 1 against the ramp surface of the safety door slider 821, the blocking piece 82 displaces upwards, driving the intermediate conductor 102 to displace, and finally making electrical contact with the contact piece 105. At this time, a path is formed between the power supply system and the output elastic piece 6. When the plug 1 leaves the output elastic piece 6, the blocking piece 82 returns to its original position, and the intermediate conductor 102 leaves the contact piece 105. At this time, an open circuit is formed between the power supply system and the output elastic piece 6. At this time, the output elastic piece 6 is not charged, which increases the safety of using the socket system.
