Description

Technical Field

[0001] The invention belongs to the field of socket boards, in particular to an active high-protection socket. Background Art

[0002] In existing power strips, when the metal plug is inserted, the protective door moves sideways, and the socket is fully open. Accidents are very likely to occur in humid environments or in the presence of metal debris, oily and explosive environments. Since the socket is not sealed and cannot withstand water and other liquids, it is easy to cause a short circuit risk. In addition, it is also easy for children to accidentally touch it, resulting in serious consequences such as electric shock.

[0003] The existing national standard protective door is made of nylon and slides sideways for safety. The contact area between the internal conductive parts of the socket and the external metal insert is wrapped with PP or PC. The gap between the materials is large, resulting in high friction resistance when the protective door moves left and right, making it easy to damage. Furthermore, there is a groove between the top of the protective door and the socket panel, which easily accumulates dust and dirt. After the metal insert is inserted, it will fall into the connection between the metal insert and the internal copper sheet, causing a short circuit. Furthermore, because the three-pole protective door is an integrated design with a spring as a recovery device, the positive and negative poles are conductive, which can easily cause an internal short circuit. When the metal insert is inserted into the socket, part of the metal insert will still be exposed after contact with the live metal, which can easily cause electric shock if touched. Summary of the Invention

[0004] In response to the above technical problems, the present invention proposes an active high-protection socket, which is provided with a protective door slider that can move up and down inside the socket. The protective door slider is made of flexible material and is provided with a through groove for the metal plug to pass through. The elastic self-sealing property of the flexible material is utilized to ensure that the metal plug is always wrapped and protected by the protective door slider during the energized time of the insertion and removal process, and to ensure that there is no electricity when acupuncture is performed under normal circumstances. Metal of the same width and length as the metal plug must be inserted before power can be turned on.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical means:

[0006] An active high-protection socket, comprising an upper socket shell and a lower socket shell, a socket assembly is mounted between the upper and lower socket shells, and the upper socket shell is provided with a socket corresponding to the socket assembly, and a separate protective door assembly is provided inside the socket assembly corresponding to each metal insert on the plug, each protective door assembly comprises the following arranged in sequence from top to bottom along the metal insert insertion direction:

[0007] A protective door slider is provided with a through slot for the metal insert to pass through. The protective door slider is made of a flexible material. After the metal insert on the plug is inserted into the through slot, the inner wall of the through slot can be in close contact with the metal insert to achieve a sealed connection;

[0008] A clamping conductive sheet is provided with two conductive clamping sheets symmetrically arranged along the thickness direction of the metal insert, and two elastic extension sheets symmetrically arranged along the width direction of the metal insert;

[0009] An external conductive sheet having an extended conductive portion, a horizontal bearing portion, and two abutment portions symmetrically connected to both sides of the horizontal bearing portion along the width direction of the metal insert, wherein the abutment portions are located outside the elastic extension sheet;

[0010] A clamping spring is provided at the upper end of each of the two elastic extension pieces. A slot for the metal insert to pass through is left between the inner sides of the two clamping springs. The clamping spring has an elastic cantilever extending toward the outer side of the slot.

[0011] The protective door slider is connected to a vertically arranged force transmission rod on the left and right sides of the through slot, respectively. When the insert is not inserted, the top of the outer end of the elastic cantilever contacts and connects with the bottom end of the force transmission rod;

[0012] an insulating pad, disposed between the horizontal bearing portion and the clamping conductive sheet;

[0013] When the metal insert is inserted into and passes through the through slot on the protective door slider, a plug-in seal can be achieved between the metal insert and the through slot;

[0014] The metal insert continues to move downward and squeezes the ends of the two elastic cantilevers on the two retaining springs that are adjacent to the insertion slot, so that the ends of the two elastic cantilevers that are away from the insertion slot can tilt upward and push the protective door slider upward through the force transmission rod, thereby wrapping the metal insert.

[0015] The metal insert continues to descend, and the retaining spring continues to deform until the two elastic cantilevers are in a vertical state and slide into the gap between the force transmission rod and the metal insert, and no longer pry the protective door slider. At this time, the protective door slider descends together with the metal insert, and the metal insert contacts the clamping conductive sheet, squeezing the two elastic extension sheets outward until they abut against the abutment portion on the external conductive sheet and energize.

[0016] When the metal plug is pulled out upward, the protective door slider moves upward with the metal plug, and the retaining spring returns to its position, the clamping conductive sheet is disconnected from the external conductive sheet, and the power is cut off. Then the metal plug is pulled out from the protective door slider. The process is completely protected and the power is prevented. After the metal plug is completely removed, the protective door is reset.

[0017] An independent chamber for accommodating the protection door assembly is provided at the bottom of the socket upper shell, and the protection door slider can move up and down along the insertion direction of the metal insert in the chamber.

[0018] The protective door slider comprises a PC material body and a silicone layer covering the outside of the PC material body.

[0019] The side where the socket upper shell and the socket lower shell contact each other is sealed by a mother-and-child clamping groove and a sealing gasket.

[0020] The socket is a two-phase socket or a three-phase socket. Beneficial effects

[0021] First, the active high-protection socket disclosed in the present invention has an upper shell made of PC material. The protective door in the socket adopts a protective door slider that can move up and down, and the protective door slider is made of PC+silicone soft material. The protective door slider is provided with a through groove for the metal insert to pass through. After the metal insert on the plug is inserted into the through groove from the socket hole on the upper shell of the socket, the soft material on the surface of the protective door slider can be in close contact with the metal insert to achieve sealed plug-in.

[0022] Second, in the active high-protection socket of the present invention, after the metal plug is inserted, it contacts the retaining spring under the protective door slider. Using the lever principle, the protective door slider moves upward, actively protecting and wrapping the metal plug. After the retaining spring reaches a certain position, it moves downward with the metal plug, ensuring that the entire plugging and unplugging process is under the protection of the protective door slider, avoiding electric shock when holding the plug.

[0023] Fourth, the active high-protection socket of the present invention has a separate protective door assembly inside the socket assembly corresponding to each metal plug on the plug. When inserting, the protective door slider first wraps the inserted metal plug. Before the bottom is turned on, all the metal plugs are wrapped in the protective door slider. When pulled out, the protective door slider floats up with the metal plug to ensure that the metal plug is still wrapped in the protective door slider before the bottom is powered off, ensuring that the metal plug is always under the wrapping protection of the protective door slider during the energized time of the insertion and removal process.

[0032] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0033] like Figure 1 As shown, an active high-protection socket includes a socket upper shell 1 and a socket lower shell 2. A socket assembly is installed between the socket upper shell 1 and the socket lower shell 2, and the socket upper shell is provided with a jack corresponding to the socket assembly. A separate protective door assembly 3 is provided inside the socket assembly corresponding to each metal insert 4 on the plug. Each protective door assembly 3 includes the following arranged in sequence from top to bottom along the metal insert insertion direction:

[0034] The protective door slider 3-1 is made of PC+silicone material and is provided with a through slot for the metal insert 4 to pass through;

[0035] The clamping conductive sheet 3-2 is provided with two conductive clamping sheets symmetrically arranged along the thickness direction of the metal insert 4, and two elastic extension sheets 3-7 symmetrically arranged along the width direction of the metal insert;

[0036] The external conductive sheet 3-3 has an extended conductive portion, a horizontal bearing portion, and two abutment portions 3-8 symmetrically connected to both sides of the horizontal bearing portion along the width direction of the metal insert, and the abutment portions 3-8 are located outside the elastic extension sheet 3-7;

[0037] A retaining spring 3-6 is provided at the upper end of each of the two elastic extension pieces 3-7. A slot for the metal insert 4 to pass through is left between the inner sides of the two retaining springs 3-6. The retaining spring 3-6 has an elastic cantilever extending toward the outside of the slot. The outer end top of the elastic cantilever is connected to the protective door slider 3-1 via a force transmission rod 3-5.

[0038] The insulating pad 3 - 4 is arranged between the horizontal bearing portion and the clamping conductive sheet 3 - 2 . Example

[0039] The difference between this embodiment and embodiment 1 is that the material of the socket upper shell 1 is silicone material. After the metal insert on the plug is inserted into the socket, the hole wall of the socket can be in close contact with the metal insert to achieve preliminary sealing, thereby further ensuring the sealing effect. Example

[0040] An independent chamber for accommodating the protection door assembly is provided at the bottom of the socket upper shell, and the protection door slider can move up and down along the insertion direction of the metal insert in the chamber.

[0041] The sealing structure between the upper shell and the lower shell of the socket realizes a sealed connection. The letter groove + silicone pad is used to perform single-pole independent sealing to prevent internal short circuit.

[0042] The waterproof principle of the present invention:

[0043] like Figure 4 As shown, the waterproof socket disclosed in the present invention, the protective door slider is made of PC+silicone soft material, and is provided with a through groove for the metal insert to pass through. When the metal insert is inserted into and passes through the through groove on the protective door slider, the silicone elasticity is used to seal the through groove by itself, and the metal insert and the through groove can be plugged in and sealed, thereby ensuring sealing.

[0044] The protective door uses an up and down movable protective door slider. After the metal insert passes through the through slot, it contacts the retaining spring under the protective door slider. Using the lever principle, the retaining spring presses down inside and tilts up outside, causing the protective door slider to move upward and wrap around the metal insert. As more metal inserts are inserted, the retaining spring reaches a vertical state and no longer pries the protective door slider. The protective door slider then descends with the metal insert until it contacts the socket copper sheet and squeezes the side of the socket copper sheet against the conductive copper sheet on the outer wall.

[0045] When the plug is pulled out, the metal plug moves upward, and the protective door slider moves upward with the metal plug. At the same time, the retaining spring returns to its position, the copper piece of the socket disengages and the power is cut off. Then the metal plug is pulled out from the protective door slider. The process is completely protected and the power is prevented. After the metal plug is completely removed, the protective door resets.

[0046] The active high-protection socket of the present invention has a separate protective door assembly inside the socket assembly corresponding to each metal plug on the plug. When inserting, the protective door slider first wraps the inserted metal plug. Before the bottom is turned on, the metal plug can be ensured to be wrapped by the protective door slider. When unplugging, the protective door slider floats up with the metal plug to ensure that the metal plug is still wrapped by the protective door slider before the bottom is powered off, ensuring that the metal plug is always wrapped and protected by the protective door slider during the energized time of the insertion and unplugging process.
