Description

Technical Field

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

[0002] With 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 a humid environment or with metal debris, or in an oily or explosive environment. Since the socket is not sealed and cannot withstand water and other liquids, it is easy to cause a short circuit. In addition, it is also easy for children to accidentally touch it, resulting in serious consequences of electric shock.

[0003] The existing national standard protection door is made of nylon and uses a side-sliding method for safety protection. The contact part between the internal conductive parts of the socket and the external metal plug is wrapped with PP or PC material. The gap between the materials is large, and the friction resistance is large when the protection door moves left and right, which is easy to be damaged. There are still grooves above the protection door and the socket panel, which are easy to accumulate dust and dirt. After the metal plug is inserted, they will fall into the joint between the metal plug and the internal copper sheet, forming a short circuit. And because the three-pole protection door is designed as an integrated device, a spring is used as a recovery device, which leads to conduction between the positive and negative poles, which is easy to form an internal short circuit. When the metal plug is inserted into the socket, part of the metal plug is still exposed after contact with the live metal plug, and it is easy to get an electric shock when touching the metal plug. Summary of the invention

[0004] In view of the above technical problems, the present invention proposes an active high-protection socket, in which a protective door slider is provided which can move up and down inside the socket. The protective door slider is made of a 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 during the insertion and removal process, and to ensure that there is no electricity during acupuncture under normal circumstances. Metal with the same width and length as the metal plug must be inserted before electricity can be turned on.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical means: An active high-protection socket, comprising an upper socket shell and a lower socket shell, a socket assembly is installed between the upper socket shell and the lower socket shell, and the upper socket shell is provided with a socket hole corresponding to the socket assembly, and each metal plug on the plug inside the socket assembly is provided with a separate protection door assembly, and each protection door assembly includes the following components arranged in sequence from top to bottom along the direction of metal plug insertion: A protective door slider is provided with a through slot for the metal insert to pass through, and 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 sealed plug-in; 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; An external conductive sheet, comprising 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; A clamping spring is respectively provided at the upper end of the two elastic extension pieces, and an insertion slot for the metal insert to pass through is left between the inner sides of the two clamping springs, and the clamping spring has an elastic cantilever extending toward the outer side of the insertion slot; The left and right sides of the through slot on the protective door slider are respectively connected with a vertically arranged force transmission rod, and when the insert is not inserted, the top of the outer end of the elastic cantilever is in contact with the bottom end of the force transmission rod; An insulating pad, arranged between the horizontal bearing portion and the clamping conductive sheet; When the metal insert is inserted into and passes through the through slot on the protective door slider, the metal insert and the through slot can be plugged and sealed; The metal insert continues to move downward to squeeze the ends of the two elastic cantilevers on the two clips close to the insertion slot, so that the ends of the two elastic cantilevers away from the insertion slot can tilt upward and push the protective door slider upward through the force transmission rod to wrap the metal insert; The metal insert continues to move downward, 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 moves downward together with the metal insert, and the metal insert contacts the clamping conductive sheet, squeezing the two elastic extension sheets outward until they contact the abutting portion on the external conductive sheet and are energized; 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 original position, the clamped 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 from being cut off. After the metal plug is completely removed, the protective door is reset.

[0006] 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 in the chamber along the insertion direction of the metal insert.

[0007] The protective door slider comprises a PC material body and a silicone layer covering the outside of the PC material body.

[0008] The side where the socket upper shell and the socket lower shell contact each other is sealed through the mother-child clamping groove and the sealing gasket.

[0009] The socket is a two-phase socket or a three-phase socket. Beneficial Effects

[0010] First, the active high-protection socket disclosed in the present invention has an upper shell of PC material, a protective door in the socket adopts a protective door slider that is movable up and down, and the protective door slider is made of PC+silicone soft material, and a through groove is provided on the protective door slider for the metal plug to pass through. After the metal plug 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 plug to achieve sealed plug-in.

[0011] 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. The lever principle is used to make the protective door slider move upward, actively protect and wrap the metal plug, and 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.

[0012] Fourth, in the active high-protection socket of the present invention, a separate protection door assembly is respectively provided inside the socket assembly corresponding to each metal plug on the plug. When inserting, the protection door slider first wraps the inserted metal plug, and before the bottom is turned on, all the metal plugs are wrapped in the protection door slider. When pulling out, the protection door slider floats up with the metal plug, ensuring that the metal plug is still wrapped in the protection door slider before the bottom is powered off, ensuring that the metal plug is always under the wrapping protection of the protection door slider during the energized time during the insertion and removal process.

DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Example

[0015] 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 a socket upper shell is provided with a jack corresponding to the socket assembly, and a separate protective door assembly 3 is provided inside the socket assembly corresponding to each metal plug 4 on the plug, and each protective door assembly 3 includes the following components arranged in sequence from top to bottom along the metal plug insertion direction: A protective door slider 3-1, which is made of PC+silicone material and is provided with a through slot for the metal insert 4 to pass through; A 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; 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; A clamping spring 3-6 is respectively provided at the upper end of the two elastic extension pieces 3-7, and a slot for the metal insert 4 to pass through is reserved between the inner sides of the two clamping springs 3-6. The clamping spring 3-6 has an elastic cantilever extending toward the outer side of the slot, and the outer end top of the elastic cantilever is connected to the protective door slider 3-1 through a force transmission rod 3-5; The insulating pad 3 - 4 is arranged between the horizontal bearing portion and the clamping conductive sheet 3 - 2. Example

[0016] The difference between this embodiment and embodiment 1 is that the socket upper shell 1 is made of silicone material, and 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

[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 in the chamber along the insertion direction of the metal insert.

[0018] 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. The waterproof principle of the present invention: like Figure 4As 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 plug to pass through. When the metal plug is inserted into and passes through the through groove on the protective door slider, the elasticity of the silicone is used to seal the through groove by itself, and the metal plug and the through groove can be plugged in and sealed, thereby ensuring sealing.

[0019] The protective door adopts an upward and downward movable protective door slider. After the metal insert passes through the through slot, it contacts the retaining spring under the protective door slider. Utilizing the principle of leverage, the retaining spring presses down inside and tilts up outside to make the protective door slider move upward and wrap the metal insert. As more metal inserts are inserted, the retaining spring reaches a vertical state and no longer pries the protective door slider, then the protective door slider 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.

[0020] 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 sheet of the socket disengages from contact and the power is cut off. Then the metal plug is pulled out from the protective door slider. The process is completely protected and power is prevented from being cut off. After the metal plug is completely removed, the protective door is reset.

[0021] The active high-protection socket of the present invention has a separate protection door assembly inside the socket assembly corresponding to each metal plug on the plug. When inserting, the protection door slider first wraps the inserted metal plug, and before the bottom is turned on, the metal plug can be ensured to be wrapped by the protection door slider. When pulling out, the protection door slider floats up with the metal plug, ensuring that the metal plug is still wrapped by the protection door slider before the bottom is powered off, ensuring that the metal plug is always wrapped and protected by the protection door slider during the energized time during the insertion and removal process.
