DETAILED DESCRIPTION

[0034] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0035] The present invention provides a safety socket, comprising a sealing box 1, a panel 2 and a socket core part, wherein the panel 2 is provided with a plug hole 21, the sealing box 1 and the panel 2 are connected together to form a receiving space, and the socket core part is arranged in the receiving space.

[0036] The socket core part includes an insulating shell, a live wire plug, a neutral wire plug, a live wire terminal, a neutral wire terminal and four sets of non-contact switches, and the non-contact switch is a normally open switch. The plug 5 is made of a conductive spring, and the two ends of the upper conductive spring of the plug 5 are abutted together to form an X-shaped structure. When the plug pin is inserted, the two ends of the upper conductive spring of the plug 5 are separated outwards and the plug pin is clamped and fixed; when the pin is pulled out, the two ends of the upper conductive spring of the plug 5 move inwards to return to the abutting state. A first non-contact switch and a second non-contact switch are respectively provided on both sides of the live wire plug, and a third non-contact switch and a fourth non-contact switch are respectively provided on both sides of the neutral wire plug. The first non-contact switch and the second non-contact switch are located on both sides of the live wire plug perpendicular to the opening and closing direction of the plug, and the third non-contact switch and the fourth non-contact switch are located on both sides of the neutral wire plug perpendicular to the opening and closing direction of the plug. The live wire plug is electrically connected to the live wire terminal after being connected in series with the first non-contact switch and the third non-contact switch, and the neutral wire plug is electrically connected to the neutral wire terminal after being connected in series with the second non-contact switch and the fourth non-contact switch; when the pin of the plug is inserted into the live wire plug, the first non-contact switch and the second non-contact switch are closed, and when the pin of the plug is inserted into the neutral wire plug, the third non-contact switch and the fourth non-contact switch are closed. When an external conductive object is only inserted into the live wire plug or the neutral wire plug, only the first non-contact switch and the second non-contact switch can be closed at the same time, or the third non-contact switch and the fourth non-contact switch can be closed at the same time, but the first non-contact switch and the third non-contact switch cannot be closed at the same time, or the second non-contact switch and the fourth non-contact switch cannot be closed at the same time. Therefore, when an external conductive object is only inserted into one socket of the socket, the conductive object will not be charged, and the socket is safer when in use.

[0037] The socket core part can have one insulating shell or multiple insulating shells, and the upper end of each insulating shell is provided with a mutually independent live wire cavity 411 and neutral wire cavity 412, and the live wire cavity 411 and the neutral wire cavity 412 are respectively provided with a live wire plug and a neutral wire plug. Figures 1 to 5 As shown, in this embodiment, the core part of the socket has two insulating shells, that is, the socket can meet the needs of two external plugs being used simultaneously when in use.

When the pin of the external plug is inserted, the pin can simultaneously abut against the upper end surface of the inner floating member 61 in the first groove 413 when inserting the plug sheet 5, so that the inner floating member 61 in the first groove 413 can be pressed downward. The width of the inserting piece 5 is smaller than the width of the inserting pin of the external plug, so that when the inserting pin of the external plug is inserted, the inserting pin can press down the inner floating parts 61 on both sides of the inserting piece 5 at the same time.

[0039] A second groove 414 and a third groove 421 are respectively disposed on both sides of each first groove 413. The second groove 414 and the third groove 421 are located on both sides of the first groove 413 along the opening and closing direction of the plug. The second groove 414 and the third groove 421 are disposed at the lower end of the insulating housing. A first magnet 611 is disposed inside the inner floating member 61, a second magnet 63 is disposed inside the second groove 414, a third magnet 621 is disposed inside the outer floating member 62, and the outer floating member 62 is disposed in the third groove 421 in a horizontally sliding manner.

A metal sheet 622 is arranged on the side of the outer floating member 62 opposite to the introduction metal sheet 64 and the lead-out metal sheet 65. When the outer floating member 62 slides horizontally to the side of the introduction metal sheet 64 and the lead-out metal sheet 65, the metal sheet 622 abuts against the introduction metal sheet 64 and the lead-out metal sheet 65 at the same time, so that the introduction metal sheet 64 and the lead-out metal sheet 65 are electrically connected. Among them, the second magnet 63 has the same polarity on the side opposite to the first magnet 611, and the second magnet 63 has a different polarity on the side opposite to the third magnet 621. That is, the second magnet 63 and the first magnet 611 repel each other, the second magnet 63 and the third magnet 621 attract each other, and the first magnet 611 and the third magnet 621 repel each other.

[0041] In this embodiment, the insulating housing includes an upper insulating housing 41 and a lower insulating housing 42, the upper insulating housing 41 and the lower insulating housing 42 are fixedly connected together, the first groove 413 and the second groove 414 are arranged on the upper insulating housing 41, and the third groove 421 is arranged on the lower insulating housing 42. Each insulating housing includes an upper insulating housing 41 and two lower insulating housings 42, and the two lower insulating housings 42 are symmetrically arranged on both sides of the upper insulating housing 41.

Figure 8 and Fig. 9Schematic diagram of the structure of the lower insulating shell 42, the opening of the third groove 421 is arranged toward the upper insulating shell 41, and this combined structure of the insulating shell can facilitate the installation of the outer floating member 62. Two support blocks 423 are arranged on the side of the third groove 421 away from the opening, and the upper and lower ends of the support blocks 423 are respectively provided with an opening connected to the third groove 421, and the openings are used to introduce the metal sheet 64 and the lead-out metal sheet 65 into the third groove 421. A middle partition 422 is arranged in the middle of the third groove 421, and the middle partition 422 separates the third groove 421 into two parts, and the two parts of the third groove 421 correspond to the two second grooves 414 on one side of the upper insulating shell 41, respectively. Each part of the third groove 421 is provided with a support block 423, and each corresponding part is provided with an introduction metal sheet 64 and a lead-out metal sheet 65. In this embodiment, the first end of the introduction metal sheet 64 is inserted into the third groove 421 at the opening of the lower end of the support block 423, and the first end of the lead-out metal sheet 65 is inserted into the third groove 421 at the opening of the upper end of the support block 423. The first end of the introduction metal sheet 64 and the first end of the lead-out metal sheet 65 are arranged at a preset distance to achieve electrical isolation; the second end of the introduction metal sheet 64 extends downward from the bottom surface of the lower insulating shell 42, and the lead-out metal sheet 65 extends downward from the bottom surface of the lower insulating shell 42 after being bent at right angles twice. The lead-out metal sheet 65 is bent at right angles twice to form a U-shaped structure, and the U-shaped structure is covered on the upper part of the support block 423. The support block 423 can play a good supporting role for the introduction metal sheet 64 and the lead-out metal sheet 65. In this embodiment, the introduction metal sheet 64 and the lead-out metal sheet 65 are arranged vertically up and down, that is, the first end of the introduction metal sheet 64 is located below the first end of the lead-out metal sheet 65. It can be understood that in other alternative embodiments, the introduction metal sheet 64 and the lead-out metal sheet 65 can be arranged horizontally left and right, that is, the introduction metal sheet 64 and the lead-out metal sheet 65 have a gap in the horizontal direction to achieve electrical isolation.

[0042] like Fig.11 and Fig.12 As shown, it is a schematic diagram of the structure of the outer floating member 62 in this embodiment. The outer floating member 62 is made of plastic material. The outer floating member 62 is provided with a mounting groove for mounting the third magnet 621. The third magnet 621 is arranged in the mounting groove. The third magnet 621 is provided with a metal wrapping sheet 622 on the outside. The metal wrapping sheet 622 wraps the third magnet 621. The metal wrapping sheet 622 is made of elastic metal sheet. The upper and lower sides of the outer floating member 62 are respectively provided with snap-fitting protrusions. The upper and lower ends of the metal wrapping sheet 622 are respectively provided with snap buckles. The metal wrapping sheet 622 is snap-fitted to the outer floating member 62. In this embodiment, the two outer floating members 62 are connected to form an integrated structure.

[0043] Fig.10Schematic diagram of the structure of the inner floating member 61 in this embodiment, the inner floating member 61 is provided with a mounting groove for mounting the first magnet 611, and the first magnet 611 is arranged in the mounting groove of the inner floating member 61. In this embodiment, the inner floating member 61 is a T-shaped structure, and correspondingly, the upper width of the first groove 413 matches the upper end width of the T-shaped structure.

[0044] Reference Figures 3 to 5 The socket core part also includes a circuit board 8, an insulating shell is arranged on the circuit board 8, and the live wire terminal and the neutral wire terminal are connected to the side of the circuit board 8 opposite to the insulating shell. The lower ends of the lead-in metal sheet 64 and the lead-out metal sheet 65 are both welded on the circuit board 8. The circuit board 8 is provided with a circuit, and the connection between the non-contact switches and the non-contact switches and the terminal 10 are electrically connected through the circuit on the circuit board 8. The circuit board 8 can avoid the use of more metal connecting sheets or wires, so that the structure of the safety socket is simpler, the number and types of components are reduced, and it is easier to assemble.

[0045] The socket core part also includes a connecting piece 7 arranged on the outer surface of the upper insulating shell 41, including a live wire connecting piece and a neutral wire connecting piece. The upper end of the live wire connecting piece is connected to the live wire plug-in piece by passing through the upper insulating shell 41 with screws, and the lower end of the live wire connecting piece is welded to the circuit board 8. The upper end of the neutral wire connecting piece is connected to the neutral wire plug-in piece by passing through the upper insulating shell 41 with screws, and the lower end of the neutral wire connecting piece is welded to the circuit board 8. The connecting piece 7 and the non-contact switch are electrically connected through the circuit on the circuit board 8.

[0046] Furthermore, the socket core part also includes a ground wire plug, a ground wire connecting piece and a ground wire terminal. An independent ground wire inner cavity is provided at the upper end of the upper insulating shell 41. The ground wire plug is arranged in the ground wire inner cavity. The ground wire connecting piece is arranged on the outer surface of the upper insulating shell 41. The upper end of the ground wire connecting piece is connected to the ground wire plug through the upper insulating shell 41 by screws. The lower end of the ground wire connecting piece is welded to the circuit board 8. The ground wire terminal is connected to the side of the circuit board 8 opposite to the insulating shell. The ground wire connecting piece is electrically connected to the ground wire terminal through the circuit on the circuit board 8.

[0047] In order to make the safety socket waterproof, a waterproof sealing gasket 9 is provided between the sealing box 1 and the panel 2, and a waterproof sealing gasket 9 is also provided between the insulating shell and the panel 2. The waterproof sealing gasket 9 is made of soft sealing material, such as silicone rubber. This makes the safety socket have a good sealing effect. Water cannot enter from the live wire cavity 411, the neutral wire cavity 412, and the ground wire cavity, nor can it enter from between the panel 2 and the sealing plate, so the socket has a good waterproof function. Since the live wire cavity 411 and the neutral wire cavity 412 are independent of each other, even if water enters the live wire cavity 411 or the neutral wire cavity 412 through the jack on the panel 2, since the water inflow will not trigger the non-contact switch to close, it will not cause electric shock, and it is safer to use.

[0048] The panel 2 of the socket is provided with a plurality of jacks 21 corresponding to the live wire plug, the neutral wire plug and the ground wire plug of the core part of the socket, for inserting the pins of the external plug. The panel 2 and the sealing box 1 are detachably connected by screws, and an upper cover plate 3 is also provided on the outside of the panel 2, and the upper cover plate 3 is clamped on the panel 2.

[0049] The working principle of the safety socket is:

[0050] like Fig.13 As shown, when the socket is not plugged in, the first magnet 611 and the second magnet 63 in the inner floating member 61 repel each other. Under the action of the second magnet 63, the inner floating member 61 is in a free floating state, and the second magnet 63 pushes the inner floating member 61 to the upper part of the first groove 413. The panel 2 and the upper end surface of the insulating shell are in contact with each other, which can prevent the inner floating member 61 from falling out. At the same time, the third magnet 621 and the second magnet 63 in the outer floating member 62 attract each other. Under the action of the second magnet 63, the outer floating member 62 is attracted and moves in the third groove 421 to the side close to the second magnet 63, so that the metal sheet 622 on the outer floating member 62 is disconnected from the lead-in metal sheet 64 and the lead-out metal sheet 65. At this time, the four groups of non-contact switches are all in the disconnected state. Fig.14As shown, when the socket is inserted into the plug, the live wire pin and the neutral wire pin on the plug push the four inner floating members 61 downward at the same time, the live wire pin pushes the two inner floating members 61 of the first non-contact switch and the second non-contact switch to move downward, and the neutral wire pin pushes the two inner floating members 61 of the third non-contact switch and the fourth non-contact switch to move downward, and after the inner floating member 61 is inserted into the bottom of the first groove 413, due to the mutual repulsion between the first magnet 611 and the third magnet 621, under the action of the first magnet 611, the outer floating member 62 is repelled and Move in the third groove 421 to a side away from the second magnet 63, so that the metal package sheet 622 on the outer floating part 62 contacts and conducts with the lead-in metal sheet 64 and the lead-out metal sheet 65. At this time, the four groups of non-contact switches are all in the on state, the live wire plug is electrically connected to the live wire terminal through the live wire connecting piece, the first non-contact switch, and the third non-contact switch in turn, and the neutral wire plug is electrically connected to the neutral wire terminal through the neutral wire connecting piece, the second non-contact switch, and the fourth non-contact switch in turn, and the live wire plug and the neutral wire plug begin to be energized.

[0051] When an external conductive object is inserted into the socket 21 of the safety socket, it needs to have a specific shape similar to a plug pin to simultaneously push the two inner floating parts 61 on both sides of the plug 5 downward. Ordinary iron wires, awls, needles, etc. cannot simultaneously push the two inner floating parts 61; in addition, even if a conductive object similar to a plug pin is inserted into one of the sockets, such as a screwdriver, it can only make the first non-contact switch and the second non-contact switch turn on at the same time, or make the third non-contact switch and the fourth non-contact switch close at the same time. However, only when the first non-contact switch and the third non-contact switch are closed at the same time, the live wire plug is charged, and only when the second non-contact switch and the fourth non-contact switch are closed at the same time, the neutral wire plug is charged, so the safety is high and many hidden dangers of electric shock are eliminated. Therefore, the live wire plug and the neutral wire plug in the safety socket will only start to be charged after the conductive object with a specific shape similar to a plug pin is inserted into the live wire socket and the neutral wire socket at the same time, and the four groups of non-contact switches are triggered to close. Otherwise, the live wire plug and the neutral wire plug will not be charged, which increases the safety of the socket when used.
