Description

Technical Field

[0001] This application belongs to the field of electrical accessories technology, specifically relating to an electrical socket device with a locking protective door. Background Technology

[0002] Household and similar electrical outlets are widely used in residential buildings and are usually installed on walls or floors near the ground, or placed on objects such as the ground or tabletops. They are easily accessible to people, especially children or toddlers who may insert foreign objects such as paperclips, test pens, hairpins, tinder, keys, etc. into any of the outlets, posing a risk of electric shock.

[0003] To prevent foreign objects from being inserted into electrical sockets, some sockets have internal protective shutters. However, the protective shutters in most electrical sockets are complex in structure, require a large amount of materials, and are difficult to assemble, resulting in relatively high manufacturing costs.

[0004] In addition, existing technology for protective doors has poor resistance to drops and vibrations. Summary of the Invention

[0005] This application is an extension of CN117013291A, providing an electrical socket device with a locking protective door, suitable for single-phase ungrounded plugs as specified in Chinese National Standard GB 1002, American Standard NEMA 5-15P plugs, American Standard NEMA 6-20P plugs, etc., especially suitable for sockets containing T-shaped sockets. The internal structure of its protective door is simple and stable; the connection between its protective door and the socket body is simple and easy to install; its protective door can prevent foreign objects from being inserted, thus providing protection, and also meets the standard requirements for the connection electrical path of sockets with protective doors; thereby achieving the purpose of simple structure, easy assembly, and reduced manufacturing costs.

[0006] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows:

The protective door assembly includes a first protective door and a second protective door arranged sequentially along the left and right socket directions. A protective door spring is provided between the first protective door and the second protective door. The first protective door includes a first partition with a left limiting end face. The second protective door includes a second partition with a right limiting end face.

[0008] The first partition is also provided with a first self-locking protrusion, and the second partition is also provided with a second self-locking protrusion that cooperates with the first self-locking protrusion for limiting and positioning, and a third self-locking protrusion that cooperates with the left limiting end face for limiting and positioning.

[0009] Furthermore, the third self-locking protrusion is located on the left side of the second partition, corresponding to the left limiting end face, and has a square end face shape.

[0010] Furthermore, the left socket is T-shaped and is suitable for both longitudinal and transverse pins, while the right socket is suitable for longitudinal pins.

[0011] Furthermore, the first partition is provided with a first window, and the second partition is provided with a second window and an auxiliary window along its length. The second window includes a second horizontal window and a second vertical window.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the application.

[0027] Example 1:

[0028] This implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an electrical socket device with a locking protective door is proposed, including a cover plate 1 and a socket assembly 2. The socket assembly 2 includes at least one socket, which includes a left socket sleeve 211 and a right socket sleeve 212. The cover plate 1 is provided with sockets corresponding to the sockets, including a left socket 111 and a right socket 112. The electrical socket device with a locking protective door further includes a protective door assembly 3 disposed between each socket and its corresponding socket.

[0029] This embodiment uses a device with two sockets as an example, arranged one in front of the other. Each socket can be a three-prong or two-prong socket. For three-prong sockets, it also includes a grounding socket and a sleeve. The protective door assembly in this embodiment is used to protect the two sockets of the AC circuit in the sockets to prevent electric shock from foreign objects. The two sockets are illustrated with an example of a left-right arrangement. This application is not limited to the number of sockets on the device, nor to the specific arrangement of the sockets, and will not be elaborated further below.

[0030] The protective door assembly 3 is disposed between each socket and its corresponding socket. The protective door assembly 3 includes a first protective door 31 and a second protective door 32 arranged sequentially along the left and right socket directions. The first protective door 31 is inserted into the second protective door 32. A protective door spring 33 is disposed between the first protective door 31 and the second protective door 32.

[0031] Specifically, the first protective door 31 includes a first partition 314, the left end face of the first partition 314 is a left limiting end face 319, a left inclined block 310 is provided on the upper left side of the first partition 314, the left end face of the left inclined block 310 is an inclined surface, the right end face of the left inclined block 310 is provided with a left spring seat 311, and a first window 315 is provided on the first partition 314.

[0032] The second protective door 32 includes a second partition 324, on which a right inclined block 320 is provided. The right end face of the right inclined block 320 is inclined, and the left end face of the right inclined block 320 is provided with a right spring seat 321. Inner guide plates 322 are provided on both sides of the second partition 324 in the width direction to facilitate the insertion of the first protective door 31. A second window 323 and an auxiliary window 325 are provided in the length direction of the second partition 324. A slot 328 is provided between the right inclined block 320 and the second partition 324 to facilitate the passage of the first partition 314. The second protective door 32 also has a right limiting end face 329, which is provided on the lower end face of the right inclined block 320.

[0033] like Figure 2 and Figure 5As shown, a support frame 23 is provided above the socket to support the protective door assembly 3. A window corresponding to the left and right sockets is provided on the frame to allow the pin to enter the socket through the window. On the inner side of the cover plate 1, corresponding to each protective door assembly 3, a left baffle 13, a right baffle 15, an outer guide plate 19, and an upper baffle 18 are provided. During installation, the left limiting end face 319 of the protective door assembly 3 is limited by the left baffle 13, and the right limiting end face 329 of the protective door assembly 3 is limited by the right baffle 15. The left baffle 13, right baffle 15, upper baffle 18, support frame 23, and outer guide plate 19 restrict the movement of the protective door assembly 3, and the protective door assembly 3 can only move left and right. The left baffle 13 and right baffle 15 restrict the left and right movement of the protective door assembly 3, allowing it to move only within a single area in the left and right directions. The upper baffle 18 and the support frame 23 are used to prevent the protective door assembly 3 from moving up and down; the outer guide plate 19 is used to prevent the protective door assembly 3 from moving forward and backward.

[0034] In normal socket use, the plug's pin is inserted into the socket and enters the socket sleeve to achieve the effect of power transmission. When pins are inserted into both the left and right sockets, the first protective door 31 and the second protective door 32 move to the right and left respectively under the push of the pins, releasing the protection of the left and right socket sleeves; when no pins are inserted into either the left or right sockets, the first protective door 31 and the second protective door 32 form double protection for the left and right socket sleeves under the action of the protective door spring 33; when a foreign object is inserted into either the left or right socket, only the corresponding protective door moves, maintaining at least one layer of protection for the left and right socket sleeves.

[0035] In this embodiment, the electrical socket device with locking protective doors has a first protective door 31 inserted into a second protective door 32. After insertion, a first partition 314 is placed between inner guide plates 322 and passes through a slot 328. The protective door spring 33 is placed between a left spring seat 311 and a right spring seat 321. When pins are inserted into both the left and right sockets, the first window 315 and the auxiliary window 325 serve as channels for the pins to insert into the right socket, and the second window 323 serves as a channel for the pins to insert into the left socket.

[0036] In this embodiment, the left inclined block 310 is trapezoidal, with a wider joint surface with the first partition 314 and a narrower top surface. The inclined surface slopes from the lower left to the upper right, so that when the pin is inserted to squeeze the inclined surface, it pushes the first protective door 31 to move to the right.

[0037] It should be noted that the left inclined block 310 can also be other shapes, such as triangles or other irregular shapes. It is only necessary to drive the first protective door 31 to move to the right when the pin is inserted into the pressing inclined surface. The left limiting end face 319 can also be set in other positions of the first protective door 31, such as on the left inclined block 310. It is only necessary to ensure that the first protective door 31 no longer moves to the left because its left limiting end face 319 is blocked by the left baffle 13, and not to hinder the left and right movement of the second protective door 32. Furthermore, the position of the left inclined block 310 on the first partition 314 can also be set slightly to the right. Setting it on the far left is the best option, as it can reduce the length of the first protective door 31. This will not be elaborated here.

[0038] In this embodiment, the right inclined block 320 is trapezoidal, with a wider joint surface with the second partition 324 and a narrower top surface. The inclined surface slopes from the lower right to the upper left, so that when the pin is inserted to squeeze the inclined surface, it pushes the second protective door 32 to move to the left.

[0039] It should be noted that the right inclined block 320 can also be other shapes, such as triangles or other irregular shapes. It is only necessary to push the second protective door 32 to the left when the pin is inserted into the pressing inclined surface. The right inclined block 320 is located on the right side of the second partition 324. The specific position is set so as to protect the sleeve when the pin is not inserted and facilitate the insertion of the pin into the sleeve when the pin is inserted. The right limiting end face 329 can also be set in other positions of the second protective door 32, such as the right end face of the second partition 324 or the outer side of the inner guide plate 322. It is only necessary to ensure that the second protective door 32 is no longer moved to the right due to the right limiting end face 329 being blocked by the right baffle 15, and not to hinder the left and right movement of the first protective door 32. This will not be elaborated here.

[0040] In this embodiment, the first partition 314 is provided with a first window 315, and the second partition 324 is provided with a second window 323 and an auxiliary window 325 along its length. The first window 315 and the auxiliary window 325 serve as channels for inserting the pins into the right socket when pins are inserted into both the left and right sockets; the second window 323 serves as a channel for inserting the pins into the left socket when pins are inserted into both the left and right sockets.

[0041] These windows are designed to provide channels for the pin to be inserted into the socket when the pin is inserted. These channels are blocked by the first and second protective doors when no plug or other foreign object is inserted, thus protecting the socket.

[0042] Example 2:

[0043] This embodiment is an improvement on embodiment 1, mainly by adding a locking structure, which improves the drop resistance and vibration resistance of the protective door assembly 3, and ensures the structural stability of the assembled protective door assembly 3.

[0044] In this embodiment, the first partition 314 is further provided with a first self-locking protrusion 316, and the second partition 324 is further provided with a second self-locking protrusion 3262 that cooperates with the first self-locking protrusion 316 for limiting and positioning, and a third self-locking protrusion 3263 that cooperates with the left limiting end face 319 for limiting and positioning.

[0045] Specifically, the first partition 314 is provided with a first self-locking protrusion 316, and the second partition 324 is provided with a second self-locking protrusion 3262 and a third self-locking protrusion 3263. When the first protective door 31 is inserted into the second protective door 32 and the protective door spring 33 is installed, under the restriction of the inner guide plate 322, the first protective door 31 can only move left and right, and under the action of the spring force of the protective door spring 33, it moves in the direction away from the second protective door 32 until the second self-locking protrusion 3262 blocks the first self-locking protrusion 316, or the third self-locking protrusion 3263 blocks the left limiting end face 319 and stops moving, thereby preventing the first protective door 31 from disengaging from the second protective door 32.

[0046] The second self-locking protrusion 3262 limits the first self-locking protrusion 316, and the third self-locking protrusion 3263 limits the left limiting end face 319, which improves the drop resistance and vibration resistance of the protective door assembly and ensures the structural stability of the assembled protective door assembly 3.

[0047] It should be noted that the third self-locking protrusion 3263 can be set at any position on the second protective door 32 corresponding to the left limiting end face 319. Furthermore, the shape of the third self-locking protrusion 3263 can be any suitable structure, such as an end face, protrusion, slot, or other structure, as long as it has an interlocking limiting function and conforms to the relative displacement relationship between the first protective door 31 and the second protective door 32. In a preferred embodiment, the third self-locking protrusion 3263 is located on the left side of the second partition 324, corresponding to the left limiting end face 319, and has a square end face shape.

[0048] The first self-locking protrusion 316 can be disposed at different positions on the first protective door 31, and the second self-locking protrusion 3262 can be disposed at any position on the second protective door 32 corresponding to the first self-locking protrusion 316. The shapes of the first self-locking protrusion 316 and the second self-locking protrusion 3262 can be any suitable structure, such as an end face, a protrusion, a slot, or other structure, as long as the interlocking of the first protective door 31 and the second protective door 32 is achieved and the relative displacement relationship between the first protective door 31 and the second protective door 32 is satisfied. In a preferred embodiment, the first self-locking protrusion 316 is a protrusion disposed on the right side of the first partition 314, and the second self-locking protrusion 3262 is the recessed portion on both sides of the right inclined block 320.

[0049] Example 3:

[0050] The left and right pins 111 and 112 of the American standard NEMA 5-15P plug are two parallel pins, while the left and right pins 111 and 112 of the American standard NEMA 6-20P plug are one horizontal and one vertical.

[0051] like Figure 1 As shown, this embodiment is applicable to both American standard NEMA 5-15P plugs and American standard NEMA 6-20P plugs. Its left socket 111 is a T-shaped socket, which is applicable to both vertical and horizontal pins, while the right socket 112 is only applicable to vertical pins.

[0052] To accommodate the shape of the two sockets, one horizontal and one vertical, this embodiment has made improvements to the protective door assembly 3.

[0053] Specifically, such as Figure 4 , Figure 5 As shown, the second window 323 includes a second horizontal window 3231 and a second vertical window 3232. The second horizontal window 3231 is used to insert the left horizontal pin 511, and the second vertical window 3232 is used to insert the left vertical pin 512.

[0054] The second horizontal window 3231 is an elastic scissor-shaped structure, comprising two inclined planes 32311 facing each other, which can be opened or closed under the action of external force.

[0055] like Figure 4 (c) and Figure 5 As shown in (b), the second partition 324 has inner guide plates 322 on both sides in the width direction to facilitate the insertion of the first protective door 31. Two inclined bodies 32311 are located at the left end of the second partition 324. The inner guide plates 322 are provided with opening grooves 327 corresponding to the positions of the inclined bodies 32311.

[0056] like Figure 5 As shown in (a), an outer guide plate 19 is provided on the inner side of the cover plate (1), and two opposing closed protrusions 191 are provided on the inner side of the outer guide plate 19.

[0057] It should be noted that the functions of the second vertical window 3232, the first window 315 and the auxiliary window 325 are the same as in Embodiment 1, and will not be repeated here.

[0058] like Figure 5As shown in (b), a second window 323 is provided on the left side of the second partition 324. The second window 323 is composed of a second transverse window 3231 and a second longitudinal window 3232 that are connected as one piece. The left side of the second partition 324 is designed as an elastic structure. The second transverse window 3231 is composed of two openable inclined bodies 32311, shaped like scissors. The inclined surfaces of the two inclined bodies 32311 are inclined towards each other. Under the elastic force of their own materials, the two inclined bodies 32311 close naturally.

[0059] Specifically, such as Figure 5 As shown in (a), the first protective door 31 moves to the leftmost end under the action of the protective door spring 3, blocking the second horizontal window 3231. The second protective door 32 moves to the rightmost end under the action of the protective door spring 33. The two closed protrusions 191 on the inner side of the outer guide plate 19 press the left outer side of the second partition 324, thereby forming a squeezing force in the opening and closing direction of the two inclined bodies 32311 of the second horizontal window 3231, so that the second horizontal window 3231 is in a forced closed state, preventing the left horizontal pin 511 from passing through the second horizontal window 3231.

[0060] like Figure 5 (d) Figure 6 (a) Figure 6 As shown in (b), when the left transverse pin 511 and the right pin 52 (e.g., the neutral pin and phase pin of the American standard NEMA 6-20P) are simultaneously inserted downwards from the left socket 111 and the right socket 112 respectively, on the one hand, the lower end of the right pin 52 pushes the second protective door 32 to the leftmost end, and the auxiliary window 325 moves to the right socket 112 directly below it. At the same time, the two closing protrusions 191 enter the corresponding opening grooves 327, eliminating the squeezing force acting on both sides of the second partition 324. That is, the opening and closing direction of the two inclined bodies 32311 is not squeezed by external force, and the two inclined bodies 32311 close naturally. On the other hand, the lower end of the left transverse pin 511 pushes the first protective door 31 to the rightmost end, and the first window 315 moves to the right directly below the right socket 112. At the same time, the obstruction above the second transverse window 3231 is pushed open. That is, under the push of the left transverse pin 511 and the right pin 52, the squeezing force and obstruction on the second transverse window 3231 are eliminated, so that the second transverse window 3231 is in a free state. At this time, the end of the left transverse pin 511 squeezes and separates the two scissor-shaped bevels 32311 of the second transverse window 3231 until the left transverse pin 511 passes through the second window 323 and contacts the left sleeve 211; at the same time, the right pin 52 passes through the first window 315 and the auxiliary window 325 until it contacts the right sleeve 212.

[0061] like Figure 5 (c) Figure 6As shown in (c), when the right pin 52 and the left longitudinal pin 512 (e.g., the phase and neutral wires of a single-phase plug without grounding in GB1002, or the phase and neutral pins of NEMA5-15P in the United States) are simultaneously inserted from the right socket 111 and the left socket 112, the second longitudinal window 3232 moves to below the left socket 111, the left inclined block 310 is pushed to the right, and the left longitudinal pin 512 can pass directly through the second longitudinal window 3232 until it contacts the left socket 211; at the same time, the right pin 52 passes through the first window 315 and the auxiliary window 325 until it contacts the right socket 212.

[0062] like Figure 6 (d) Figure 6 As shown in (e), when a single foreign object is inserted into the left socket 111, the foreign object pushes the left inclined block 310, causing the first protective door 31 to move to the right. However, since the second protective door 32 is at the rightmost end, the second window 323 is not below the left socket 111, and the two closed protrusions 191 on the inner side of the outer guide plate 19 press against the outer left side of the second partition 324, the second transverse window 3231 is forced closed due to lateral pressure, effectively preventing the foreign object from passing through the protective door and contacting the left socket 211.

[0063] like Figure 6 As shown in (f), when a single foreign object is inserted into the right socket 112, the foreign object pushes the right inclined block 320, causing the second protective door 32 to move to the left. However, since the first protective door 31 is at the leftmost end, the first window 315 is not below the right socket 112, effectively preventing the foreign object from passing through the protective door and contacting the right socket 212.

[0064] It should be noted that this device includes at least one socket, which can be installed or moved in any direction, but changes in its spatial position will not alter the relative positional relationships between the electrical socket and its protective door components. For the sake of representing three-dimensional views, a horizontally placed electrical socket with two outlets distributed left and right is used to represent the positional relationships of the components and parts. This leads to the relative relationships of up / down, left / right, and front / back in this specification. The descriptions of up / down, left / right, and front / back do not affect the scope of protection covered by the claims of this application. The "plates" or "frames" in the left baffle, right baffle, upper baffle, support frame, outer guide plate, and rear guide plate can all be composed of one or more strips, blocks, plates, or combinations thereof, and can be positioned at different locations on the cover plate or socket assembly to achieve the function of blocking or limiting the relevant components of the protective door assembly in spatial orientation. The "blocks," "plates," and "surfaces" contained in the left inclined block, first partition, left limiting end face, right inclined block, second partition, right limiting end face, and inner guide plate can all be composed of one or more strips, blocks, plates, surfaces, or combinations thereof. They can be set at different positions of the relevant components, and their structures correspond one-to-one with the structures of the relevant components and parts of the cover plate and socket assembly in spatial orientation, so as to achieve the function of limiting the relative positions between components. Structures not given reference numerals in the figures do not affect the technical solution of this application and will not be described in detail here.

[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The embodiments described above are merely specific and detailed examples of the embodiments described in this application, and should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
