Description

[0001] This application claims priority to "pop-out socket" filed on October 18, 2024, with application number 202422524163.1, originally accepted by the Chinese agency. Technical Field

[0002] This utility model relates to the field of sockets, specifically a plug-in easy-to-unplug socket. Background Technology

[0003] Depending on the installation method, sockets can be divided into wall sockets fixed to the wall and portable power strips with power cords that can be moved freely. A typical socket usually has the following main components: the outermost panel, the sockets on the panel, safety shutters, metal springs, and terminals. The safety shutters act as a barrier to prevent electric shock; they can only be pushed open when two or three prongs of the plug are inserted simultaneously and in parallel, preventing fingers or foreign objects from being inserted into a single socket and causing electric shock. The metal springs are located behind the safety shutters; one end of the springs clamps the plug prongs to form an electrical connection, and the other end is connected to the terminals by riveting or soldering. The terminals are used to connect the electrical wires.

[0004] Currently available sockets, due to the presence of metal contacts, result in plugs that are easy to insert but difficult to remove. When a plug is inserted, the metal contacts slide along the inclined surface of the contacts. During this process, the pushing force applied to the plug is decomposed into two forces: one force causes the contacts to open outwards, and the other force pushes the plug forward. Because of the inclined surface, the friction force overcome during insertion is relatively small, making it easy to insert. However, when the plug is removed, the metal contacts are parallel to the inner wall of the contacts, and there is no inclined surface to utilize. Removing the plug requires overcoming the static friction force applied by the contacts, resulting in a much greater force required to remove the plug than when inserting it. This design is intended to prevent the plug from loosening and generating an electric arc, requiring a tighter insertion for safety. However, for vulnerable groups such as the elderly and children, a looser plug is preferable for easier removal. Existing sockets with easy-to-insert but difficult-to-remove designs are clearly unsuitable for these groups. Therefore, while maintaining safety, there is an urgent need to design a socket with easy-to-remove plugs. Utility Model Content

[0005] To avoid and overcome the technical problems existing in the prior art, this utility model provides an easy-to-unplug socket. This utility model ensures the safety of the socket while making the plug easy to unplug, facilitating use by people with weak strength.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A plug-in receptacle includes a panel and a protective cover that mates with the panel along the plug insertion direction. The receptacle's electrical connection components and the protective cover have plug holes at corresponding positions. It also includes an elastic element that applies an elastic force to the protective cover along the plug removal direction. The elastic force applied by the elastic element to the protective cover is greater than the clamping force applied by the metal spring inside the receptacle to the plug pins. The receptacle has a sliding post arranged parallel to the panel, which slides along the direction parallel to the panel after being driven by a pressing source.

[0008] The end face of the protective cover adjacent to the power connection component is provided with a locking component, and the sliding column is provided with a locking component. The locking component is configured such that when the protective cover is pressed into the panel and the sliding column slides to the set position, the locking component performs a locking action on the locked component to restrict the movement of the protective cover along the plug pulling direction; when the locking component unlocks the locked component, the protective cover is driven by the elastic element to push the plug out.

[0009] As a further embodiment of this utility model: the base of the socket is provided with a guide seat that slides and engages with the slide post. The end of the slide post away from the guide seat is the driving end. A return spring is sleeved on the slide post. The two ends of the return spring abut against the guide seat and the slide post respectively, thereby applying an elastic force away from the guide seat along the axial direction of the slide post. The pressing source applies a driving force towards the guide seat to the slide post.

[0010] As a further improvement of this utility model: the pressing source of the slide column is a button that abuts against the driving end of the slide column. When the button is pressed, it drives the slide column to slide towards the guide seat to unlock the protective cover.

[0011] As a further improvement of this utility model: the button slides in conjunction with the panel along the plug insertion direction, and the contact surface of the button and / or the drive end is a guide slope.

[0012] As a further improvement of this utility model: a button spring is provided inside the socket to match the button, and the button spring applies an elastic force to the button in the direction of plug pulling out.

[0013] As a further improvement of this utility model: the button slides along the sliding direction of the guide seat and engages with the panel or base, and the end face of the button abuts against the driving end of the guide seat.

[0014] As a further improvement of this utility model, the driving end of the slide column extends outside the socket to form a pressing source.

[0015] As a further embodiment of this utility model: the locked component is a cover plate latch arranged on the protective cover plate, and the locking component is a slide pin latch arranged on the slide pin. Both the cover plate latch and the slide pin latch are horizontally protruding with a locking tongue. The locking tongues of the cover plate latch and the slide pin latch abut against each other to lock the protective cover plate.

[0016] Alternatively, the locked component and the locking component are a positioning post and a locking post, respectively. The positioning post has a pin hole along the radial direction, and the locking post has a positioning pin protruding horizontally along the upper edge. The positioning pin and the pin hole are inserted and engaged to lock the protective cover plate.

[0017] Alternatively, the locked component and the locking component are a positioning post and a locking post, respectively. The positioning post and the locking post are equipped with magnetic components, and the positioning post and the locking post are magnetically positioned to lock the protective cover.

[0018] As a further improvement of this utility model: the protective cover is provided with an outward flange, and the elastic element is arranged between the outward flange of the protective cover and the panel.

[0019] As a further embodiment of this utility model: the panel is fastened to the base and forms a mounting cavity with the base for the installation of the power connection component. The power connection component includes a sensor panel that controls the power supply to and from the three-hole or two-hole socket on an independent control socket. The power connection component also includes a safety door disposed on the surface of the corresponding three-hole and / or two-hole socket. The safety door is configured to switch between the following two working states:

[0020] Safety door cover with insertion hole;

[0021] The safety door slides out of the socket position after being pressed by the plug.

[0022] The safety door is equipped with a sensor magnet. When the sensor magnet on the safety door moves, the sensor panel will energize the socket under the safety door corresponding to the sensor magnet.

[0023] As a further embodiment of this utility model: the power connection component includes a safety door base and a safety door cover plate. Each safety door is slidably mounted on the safety door base. Guide posts are provided at the four corners of the safety door cover plate, and the elastic element is a spring sleeved on the guide posts. The sensing panel is fixed on the safety door cover plate or the safety door base, and a Hall sensor is provided on the sensing panel to detect the displacement distance of the sensing magnet.

[0024] As a further improvement of this utility model: a sensor light is provided on the panel;

[0025] The sensor light is configured to turn on when any set of sockets is powered on;

[0026] Alternatively, the sensor light is configured to turn on when physically touched or triggered by sound.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] 1. This utility model eliminates the need for forceful plug removal. Simply press the sliding pin, and the protective cover automatically pops the plug out under the action of the elastic element. Through the locking and unlocking mechanism between the lateral sliding of the sliding pin and the longitudinal movement of the protective cover, the simple pressing action is transformed into a precise release action of the protective cover. This solves the problem of difficulty in plug removal caused by the clamping force of metal springs in traditional sockets. While ensuring the safety of the socket, the plug is easy to insert and remove, making it convenient for people with weak strength. The presence of the protective cover also allows the plug to be pre-inserted into the socket hole of the protective cover before being inserted into the socket, preventing accidental contact with the plug pins during insertion. Especially for children, whose hands are smaller, they tend to grip the plug tightly when removing it, and their clenched fingers are more likely to come into contact with the plug pins, causing electric shock. The one-button press-to-pop design not only makes it easy to remove the plug but also significantly reduces the possibility of electric shock for children.

[0029] 2. The reset spring in this utility model ensures that the slide column automatically returns to its original position after each unlocking action, preparing for the next locking action. By setting an independent button, the guide slope design can directly convert the vertical pressing force of the button into the horizontal movement of the slide column, optimizing the internal space layout of the socket. At the same time, the button spring allows the button to automatically spring back to its original position after being pressed, preparing for the next unlocking of the protective cover. In addition, the button can also be arranged in the same direction as the slide column, or the slide column can be directly extended as a button to simplify the number of parts. Pressing the slide column directly unlocks the protective cover, providing a flexible unlocking method.

[0030] 3. This utility model provides a flexible locking method for the protective cover by forming a mechanical interlock through the rigid contact of the locking tongue or positioning pin, or by forming an indirect lock through magnetic attraction, ensuring that the plug will not loosen due to accidental contact during use; the elastic element is placed between the outer flange of the protective cover and the panel, so that the protective cover can move within a set range, ensuring that the protective cover will not detach from the panel.

[0031] 4. This utility model ensures that the circuit is only connected when the plug is fully inserted and the safety door is pushed to the designated position, and the magnet is detected by the Hall sensor. This achieves the safety protection of powering on only after the plug is fully inserted. As long as the safety door is not pushed open correctly and completely, the socket will never be energized, eliminating the risk of electric shock when a conductive object is inserted halfway into the socket. The system can also accurately sense which socket is in use and supply power independently. The sensor light can be set to indicate that the socket is powered on and in working condition, making it easy for users to quickly locate it in dim environments. It can also be set as a touch or voice-activated night light for convenient lighting. Attached Figure Description

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Please see Figures 1-5In this embodiment of the utility model, a plug-and-play socket is provided. The socket can be any one of a wall socket, a cube socket, or a power strip. The panel 1 is fastened to the base 3, together forming a mounting cavity for accommodating internal components. A slot is cut into the panel 1 for the installation of a protective cover 2. The protective cover 2 slides with the slot on the panel 1 or is engaged by rolling wheels, and its sliding direction is consistent with the direction of plug insertion / removal. Both the protective cover 2 and the safety door cover 52 of the power connection component 5 have plug holes 21 corresponding to the positions of the wiring terminals inside the power connection component 5 to ensure that the plug can be smoothly inserted.

[0049] The outer ring of the protective cover 2 may be provided with an outward flange 23, which abuts against the panel 1 to prevent the protective cover 2 from detaching from the panel 1. In another embodiment, the protective cover 2 may not be provided with an outward flange 23, and after unlocking, the plug will pop out together with the elastic member 6 and detach from the panel 1.

[0050] The elastic element 6 is installed inside the socket, and the protective cover 2 applies an elastic thrust along the direction of plug withdrawal. The elastic element 6 can be any of the following elastic elements: spring, disc spring, elastic diaphragm, metal bellows, rubber ring, etc. The fixing method of the elastic element 6 is not limited; it can be fixed to the panel 1 or the base 3. In this embodiment, guide posts are set at the four corners of the safety door cover 52 of the power connection component 5. Each guide post is fitted with a spring. The area enclosed by the four sets of guide posts corresponds to the outer contour size of the protective cover 2, and the edge of the protective cover 2 abuts against the spring on the guide post.

[0051] A sliding post 4 is mounted on the base 3, parallel to the panel 1. The sliding post 4 is parallel to the surface of the panel 1. To fix the sliding post 4, a guide seat 31 is provided on the base 3. The sliding post 4 passes through the guide seat 31 and slides with it. The sliding direction of the sliding post 4 is parallel to the surface of the panel 1. A return spring 42 is fitted over the sliding post 4. One end of the return spring 42 abuts against the guide seat 31, and the other end abuts against the sliding post latch 43 on the sliding post 4. Alternatively, a boss or retaining ring structure can be directly provided on the sliding post 4 to limit the return spring 42. The return spring 42 applies an elastic force to the sliding post 4 in a direction away from the guide seat 31. When the sliding post 4 moves away from the guide seat 31, it is in a locked state of the protective cover 2; when the sliding post 4 moves towards the guide seat 31, it is in an unlocked state of the protective cover 2.

[0052] To drive the slide column 4, a pressing source is needed to press the slide column 4. The end of the slide column 4 away from the guide seat 31 is the driving end 41, which cooperates with the pressing source.

[0053] In one embodiment of the pressing source, the pressing source is a button 11, which can be arranged on the panel 1, with the pressing direction parallel to the insertion direction of the plug. The end of the button 11 adjacent to the driving end 41 of the slide column 4 is the working end. At least one end of the working end of the button 11 and the driving end 41 is set as a guide slope 411. When the button 11 is pressed, the guide slope 411 converts the vertical pressing force into a horizontal component force, pushing the slide column 4 to move towards the guide seat 31. In this embodiment, both the working end and the driving end 41 of the button 11 are set as guide slopes 411. In actual use, the guide slope 411 is not limited to a completely straight surface and can also have a certain curvature.

[0054] In another embodiment of the pressing source, the pressing source is also a button 11. The button 11 can be arranged on the panel 1 or on the base 3. Its position is determined by the position of the slide column 4. The button 11 and the slide column 4 are arranged in a square shape along the slide column 4. The end of the button 11 abuts against the driving end 41 of the slide column 4. Pressing the button 11 can directly push the slide column 4 to slide.

[0055] In the above embodiment where button 11 is used as the pressing source, a button spring 111 can be installed on button 11. The button spring 111 applies an elastic restoring force to button 11. The position of button spring 111 is not limited, as long as it avoids the position of slide column 4 and does not affect the normal operation of slide column 4. When the elastic force of the return spring 42 is large enough, button spring 111 may not be provided. The return spring 42 drives slide column 4 to reset, and slide column 4 drives button 11 to reset synchronously. A spring seat and a convex ring or other conventional spring mounting mechanism can be provided on button 11 to install button spring 11. A limiting ring or flange or other structure can be provided on button 11 to abut against panel 1 to prevent button 11 from detaching from panel 1.

[0056] In another embodiment of the pressing source, the structure is further simplified by extending the driving end 41 of the slide column 4 directly and exposing it on the side of the socket or at a specific opening, so that the driving end 41 of the slide column 4 can be directly used as a pressing source for pressing.

[0057] To enable locking and unlocking of the protective cover 2, a locking component is provided on the end face of the protective cover 2 adjacent to the power connection component 5, and a locking component is provided on the sliding column 4.

[0058] In one embodiment of the locking component and the locked component, the locking component is a sliding pin latch 43, and the locked component is a cover plate latch 22. Both the sliding pin latch 43 and the cover plate latch 22 include a set of positioning pins arranged perpendicular to the surface of the panel 1. Both the sliding pin latch 43 and the cover plate latch 22 have horizontally protruding latches forming a locking tongue. Under the action of the return spring 42, the locking tongue of the sliding pin latch 43 is located directly below the locking tongue of the cover plate latch 22. The side of the locking tongue of the sliding pin latch 43 away from the panel 1 is a flat surface for positioning and locking, while the side of the locking tongue of the sliding pin latch 43 adjacent to the panel 1 is a sloped or curved surface for sliding guidance. The side of the locking tongue of the cover plate latch 22 away from the base 3 is a flat surface for positioning and locking, while the side of the locking tongue of the cover plate latch 22 adjacent to the base 3 is a sloped or curved surface for sliding guidance. When the cover plate latch 22 and the sliding pin latch 43 move toward each other, they first form a sliding guide through the inclined surface or arc surface, pushing the sliding pin 4 to move toward the guide seat 31 and then resetting, so that the cover plate latch 22 and the sliding pin latch 43 abut against each other in the plane direction, thereby achieving locking.

[0059] Specifically, during the locking process, when the plug is inserted, it pushes the protective cover 2 into the socket, compressing the elastic element 6. As the protective cover 2 is pressed into place, the latch on the cover latch 22 abuts against the latch on the sliding pin latch 43, pushing the sliding pin 4 towards the guide seat 31 before resetting. The latch of the sliding pin latch 43 moves above the latch of the cover latch 22, forming an upper and lower abutment, thus preventing the protective cover 2 from popping outwards under the action of the elastic element 6, achieving locking. At this time, the plug is held in the inserted state.

[0060] During the unlocking process, when the plug needs to be unplugged, the operator applies a force towards the guide seat 31 to the sliding pin 4 by pressing the source, overcoming the elastic force of the return spring 42, causing the sliding pin 4 to slide. The sliding pin latch 43 moves accordingly, and its latch disengages from the latch of the cover plate latch 22, thus releasing the lock. The protective cover plate 2, under the pushing force of the elastic element 6, immediately drives the plug to move quickly out of the socket, realizing the pop-out of the plug.

[0061] Based on the above embodiments of the locking component and the locked component, there are also the following equivalent alternatives, such as pin-type locking and magnetic locking.

[0062] In the pin-type locking configuration, the locked component is a positioning post fixed to the protective cover plate 2, and the locking component is a locking post fixed to the sliding post 4. The positioning post has a radially opening pin hole, and the locking post has a horizontally protruding positioning pin. The end face of the positioning pin slides in engagement with the cylindrical surface of the locking post, and the sliding path intersects with the pin hole. When the sliding post 4 moves to the set position, under the action of the return spring 42, the positioning pin inserts into the pin hole to achieve locking.

[0063] In magnetic locking, the same positioning and locking pins are used, but magnetic assemblies with opposite poles are installed on their opposite end faces. When the protective cover 2 is pressed into place and the sliding pin 4 reaches the set position, the magnets attract each other to lock. To unlock, sufficient force must be applied to overcome the magnetic attraction to move the sliding pin 4, thus completing the unlocking process.

[0064] Panel 1 also features a sensor light 12. The sensor light 12 can be set as auxiliary lighting after touch sensing. In this mode, a touch copper foil can be installed on the socket's control board, electrically connected to the sensor light 12. The touch sensing area is located above the touch copper foil. When a hand touches this area, the control board detects the signal and activates the sensor light 12 for auxiliary lighting, helping the user accurately locate the socket. The light automatically turns off after a 30-second delay, only to be activated by another touch. Besides touch sensing, it can also be set to voice-activated, lit by a specific sound such as clapping.

[0065] The sensor light 12 can also be set to indicate the power status. When any plug is inserted into the socket, connecting one of the circuits, the sensor light 12 will light up to remind that the power is on, making it more obvious whether the circuit inside the socket is powered on and ensuring the safe use of the socket.

[0066] Two sets of sensor lights 12 can be installed on the same socket, one for auxiliary lighting and the other for power-on reminder.

[0067] The power connection assembly 5 includes a safety door base 51 and a safety door cover 52 that closes the safety door base 51. Each three-hole or two-hole socket has an independent safety door. The metal spring and wiring terminals below the safety doors of the power connection assembly 5 are existing technologies, so their structures will not be described in detail. The safety doors of this invention can be configured to conform to different forms of safety doors in accordance with national standards. The safety doors are usually held in the closed position of the socket by a spring. Only when the plug pins are inserted, overcoming the spring force to push open the safety door, can the plug pins be inserted into the metal spring. To avoid contact points, each safety door is fixed with a sensing magnet 56, and a sensing panel 521 is fixed on the safety door cover 52 or the safety door base 51. The sensing panel 521 integrates a Hall sensor. When the safety door is pushed open by the plug and causes displacement, the sensing magnet 56 moves accordingly. When the safety door is fully opened, i.e., the plug is inserted into the correct position, the Hall sensor detects a change in the magnetic field that reaches a preset threshold, and the control circuit of the sensing panel 521 powers on the corresponding socket.

[0068] Specifically, in this embodiment, the socket is a five-hole socket with two sets of safety doors: a first safety door 53 corresponding to a three-hole plug and a second safety door 54 corresponding to a two-hole plug. The first safety door 53 has a first safety door guide surface 531 corresponding to the positions of the two sets of angled prongs at the bottom of the three-hole plug, and the second safety door 54 has a second safety door guide surface 542 corresponding to the positions of the two sets of angled prongs of the two-hole plug. The first safety door 53 and the second safety door 54 slide against each other via a guide post 541, allowing them to slide towards each other or away from each other. A safety door spring 55 is mounted on the guide post 541, with its two ends abutting against the first safety door 53 and the second safety door 54, respectively. When a two-hole plug is inserted into the socket, the prongs contact the second safety door guide surface 542, and the force pushes the second safety door 54 towards the first safety door 53. The induction magnet 56 on the second safety door 54 moves synchronously, and the Hall sensor on the induction panel 521 detects the magnet signal, thereby supplying power to the two-hole plug on the terminal block. When the three-prong plug is inserted, the two angled prongs below the three-prong plug contact the first safety door guide surface 531, and the force pushes the first safety door 53 to move towards the second safety door 54. The induction magnet 56 on the first safety door 53 moves synchronously, and the Hall sensor on the induction panel 521 detects the magnet signal, thereby supplying power to the three-prong plug on the terminal block.
