Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a power socket that is protected against being pulled out. Background Technology

[0002] The plug-and-socket connection is the most common way to connect electrical appliances in daily life. Since sockets are often fixed in a certain location such as a wall, the connection between the appliance and the socket and plug is made by a wire. These wires are often exposed to the outside. In daily life, there are frequent cases of accidentally pulling or even kicking the wires, which can cause the plug to be pulled out of the socket instantly, resulting in a power outage of the appliance. In addition, many electrical appliances in daily life or many machines in industrial production are used in vibrating environments. Under strong vibration conditions, the connection between the plug and the socket can easily become detached, resulting in a power outage of the appliance.

[0003] Among existing patents, Chinese patent document with application number 201910594983.9 discloses: a safety anti-loosening socket, including a socket and a plug. The plug consists of a base and two connectors embedded at one end of the base. The socket includes a square shell. The inner wall of the shell is fixedly connected to clamping springs at corresponding positions of the connectors. The outer wall of the shell has a socket hole adapted to the connectors. An anti-loosening pressing mechanism is provided in the middle of the two clamping springs. The anti-loosening pressing mechanism includes a connecting rod fixedly connected to the inner wall of the shell. The end of the connecting rod away from the shell is fixedly connected to a support plate with a U-shaped side. The concave surface of the support plate is on the same plane as the clamping springs. The upper middle part of the support plate is provided with a sealed telescopic airbag, which is filled with a thermal expansion and contraction medium. A heating wire is horizontally placed inside the telescopic airbag. Both ends of the telescopic airbag are fixedly connected to abutment plates. The end of the abutment plates is fixedly connected to abutment plates with the same shape as the outer side of the clamping spring. Guide balls are installed at the front and rear corners of the telescopic airbag. The guide balls are rolled and connected to the inner walls of both sides of the support plate. A converter is fixedly connected to the side of the support plate away from the connecting rod. A self-resetting push-button switch is fixedly installed between the two sockets of the housing. The two clamping springs, the heating wire, the converter and the self-resetting push-button switch are connected in series and form a heating expansion circuit. This patent document describes a method that uses an electric heating wire to heat a thermostatically expanding medium inside a telescopic airbag, causing the airbag to expand and move the stop plate. This method requires a large number of electrical components and heating and expansion circuits to work together, resulting in a complex structure, high production and usage costs, and the electrical control method is prone to failure, increasing maintenance costs. Furthermore, the heating wire takes a certain amount of time to heat the thermostatically expanding medium and for the medium to cool down, resulting in a long response time and insufficient sensitivity, making it impossible to quickly lock or release the plug.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a power socket that is protected against being pulled out.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A power socket designed to prevent unplugging includes a socket housing, a cover plate, a pressing control component, a reset drive component, a live wire terminal, a neutral wire terminal, a ground wire terminal, and two rotating locking components. The back of the socket housing has a recessed cavity, and the front of the socket housing has a live wire hole, a neutral wire hole, and a ground wire hole communicating with the cavity. The cover plate is installed on the socket housing and covers the opening of the cavity. The cover plate has a protruding socket core housed within the cavity. The live wire terminal, neutral wire terminal, and ground wire terminal are triangularly arranged and embedded in the socket core. The terminals of the live wire terminal, neutral wire terminal, and ground wire terminal all extend beyond the cover plate. The neutral wire and ground wire terminals are respectively connected to the live wire hole, neutral wire hole, and ground wire hole. Two rotating locking parts are rotatably mounted on the end face of the socket core and located in the cavity. The two rotating locking parts are located between the ground wire terminal and the ground wire hole. The two rotating locking parts are arranged in a semi-enclosed manner around the ground wire terminal. The pressing control part is raised and lowered on the power socket shell. The pressing control part is connected to the cover plate via a reset drive part. The reset drive part is used to drive the pressing control part to reset and move. The pressing control part is equipped with a button and two control posts. The button can extend out of the front of the power socket shell. The two control posts are raised and lowered in the cavity. The two control posts are used to control the two rotating locking parts to move closer to each other or open.

[0008] Furthermore, the end face of the socket core is provided with a rotating shaft, which is located at the center of the live wire plug terminal, the neutral wire plug terminal and the ground wire plug terminal. One end of each of the two rotating locking parts is rotatably connected to the rotating shaft, and the two rotating locking parts are located between the two control posts.

[0009] Furthermore, the inner side of the control column is provided with an opening ramp and a locking vertical surface from top to bottom; when the locking vertical surface abuts against the middle of the rotating locking member, the two rotating locking members move closer to each other; when the middle of the rotating locking member corresponds to the opening ramp, the two rotating locking members can open to each other.

[0010] Furthermore, an abutment block is protruding from the outer side of the middle part of the rotating locking member, and the abutment block is used to abut against the vertical surface of the lock.

[0011] Furthermore, a limiting plate is provided on the end face of the socket core. The limiting plate is located on the side of the grounding terminal away from the rotating shaft. The two end faces of the limiting plate are used to abut against the other ends of the two rotating locking parts. The limiting plate is used to limit the extreme position of the two rotating locking parts approaching each other.

[0012] Furthermore, a spring sheet is bent on the inner side of the middle part of the rotating locking member, and the spring sheet can undergo recoverable elastic deformation when compressed.

[0013] Furthermore, the cover plate has a protruding guide post, the button is located on the end face of the guide post, the back of the power socket housing has a recessed guide hole, the front of the power socket housing has a through hole communicating with the guide hole, the guide post is slidably connected to the guide hole, and the button slides through the through hole.

[0014] Furthermore, the bottom surface of the guide post is recessed with a mounting cavity, one end of the reset drive is mounted on the cover plate, and the other end of the reset drive is mounted in the mounting cavity.

[0015] Furthermore, the reset drive is a spring, and the cover plate has a protruding guide rod. The spring is sleeved on the outside of the guide rod, and the guide rod can extend into the mounting cavity.

[0016] Furthermore, a protective partition is provided on the end face of the socket core. The live wire plug-in terminal and the ground wire plug-in terminal are located on the same side of the protective partition, and two rotating locking parts are located on the other side of the protective partition. The protective partition is used to separate the two rotating locking parts from the live wire plug-in terminal and the ground wire plug-in terminal.

[0017] The beneficial effects of this utility model are as follows: In practical applications, when the anti-unplug power socket is in its normal state, the pressing control component is in its highest position under the reset driving action of the reset drive component. The button of the pressing control component extends out of the front of the power socket shell, and the two control pins of the pressing control component apply pressure (locking force) to the two rotating locking components, causing the two rotating locking components to move closer together. When it is necessary to insert the plug into the anti-unplug power socket, a pressing force is applied to the button of the pressing control component, causing the pressing control component to move downward until it reaches its lowest position. At this time, the two control pins of the pressing control component release the locking force on the two rotating locking components, and the two rotating locking components can open together. At the same time, the live wire terminal, neutral wire terminal, and ground wire terminal of the plug are aligned with the live wire hole, neutral wire hole, and ground wire hole, respectively. Insert the plug into the live wire hole and ground wire hole until the live wire terminal, neutral wire terminal, and ground wire terminal are fully inserted into the live wire plug terminal, neutral wire plug terminal, and ground wire plug terminal respectively and electrically connected. This positions the ground wire terminal between the two open rotating locking members. At this point, simply release the pressure on the button of the pressing control member. The reset drive member drives the pressing control member upward and resets it, causing the button of the pressing control member to reset upward. The two control posts of the pressing control member apply an inward locking force to the two rotating locking members, causing them to rotate closer to each other and lock the ground wire terminal of the plug into the ground wire plug terminal. This ensures a secure connection between the plug and the device, preventing accidental removal, separation due to loosening, or poor contact. When it is necessary to remove the plug from the device, apply pressure to the button of the pressing control member. The two rotating locking members release the ground wire terminal of the plug, allowing the plug to be removed. This utility model has a simple structure, low production and use costs, easy and convenient operation, good anti-pull-out effect, effectively reducing the probability of accidents, and adopts mechanical transmission locking, which is stable and reliable in operation, not prone to failure, and reduces maintenance costs.

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] like Figures 1 to 7As shown, this utility model provides an anti-pull-out power socket, which includes a power socket shell 1, a cover plate 2, a pressing control component 3, a reset drive component 4, a live wire plug terminal 5, a neutral wire plug terminal 6, a ground wire plug terminal 7, and two rotating locking components 8. The back of the power socket shell 1 is recessed with a cavity 9, and the front of the power socket shell 1 has a live wire hole 10, a neutral wire hole 11, and a ground wire hole 12 communicating with the cavity 9. The cover plate 2 is installed on the power socket shell 1 and covers the opening of the cavity 9. The cover plate 2 has a protruding socket core 13, which is housed in the cavity 9. The live wire plug terminal 5, the neutral wire plug terminal 6, and the ground wire plug terminal 7 are triangularly distributed and embedded in the socket core 13. The wiring ends of the live wire plug terminal 5, the neutral wire plug terminal 6, and the ground wire plug terminal 7 all extend outside the cover plate 2 and are respectively connected to the electrical wires of the circuit. The connection is as follows: the live wire terminal 5, the neutral wire terminal 6, and the ground wire terminal 7 are respectively connected to the live wire hole 10, the neutral wire hole 11, and the ground wire hole 12. Two rotating locking parts 8 are rotatably set on the end face of the socket core 13 and located in the cavity 9. The two rotating locking parts 8 are located between the ground wire terminal 7 and the ground wire hole 12. The two rotating locking parts 8 are set in a semi-enclosed manner around the ground wire terminal 7. The pressing control part 3 is raised and lowered on the power socket shell 1. The pressing control part 3 is connected to the cover plate 2 via the reset drive part 4. The reset drive part 4 is used to drive the pressing control part 3 to reset and move. The pressing control part 3 is provided with a button 14 and two control posts 15. The button 14 can extend out of the front of the power socket shell 1. The two control posts 15 are raised and lowered in the cavity 9. The two control posts 15 are used to control the two rotating locking parts 8 to move closer to each other or open.

[0029] In practical applications, when the anti-unplug power socket is in its normal state, the pressing control 3 is in its highest position under the reset drive of the reset drive 4. The button 14 of the pressing control 3 extends out of the front of the power socket housing 1, and the two control pins 15 of the pressing control 3 apply pressure (locking force) to the two rotating locking parts 8, causing the two rotating locking parts 8 to rotate closer together. When it is necessary to insert the plug into the anti-unplug power socket, a pressing force is applied to the button 14 of the pressing control 3, causing the pressing control 3 to move downwards until it reaches its lowest position. At this time, the two control pins 15 of the pressing control 3 release the locking force on the two rotating locking parts 8, and the two rotating locking parts 8 can open apart. At the same time, the live wire terminal, neutral wire terminal, and ground wire terminal of the plug are aligned with the live wire hole 10, neutral wire hole 11, and ground wire hole 12, respectively. Insert the plug into the grounding hole 12 until the live wire terminal, neutral wire terminal, and ground wire terminal of the plug are fully inserted into the live wire plug terminal 5, neutral wire plug terminal 6, and ground wire plug terminal 7 respectively and electrically connected, so that the ground wire terminal is located between the two rotating locking members in the open state. At this time, simply release the pressing force on the button 14 of the pressing control member 3, and the reset drive member 4 drives the pressing control member 3 to move upward and reset, so that the button 14 of the pressing control member 3 resets upward. The two control pins 15 of the pressing control member 3 apply an inward locking force to the two rotating locking members 8, so that the two rotating locking members 8 move closer to each other and lock the ground wire terminal of the plug in the ground wire plug terminal 7, so that the plug can be stably plugged into the present invention and prevent the plug from being accidentally pulled out, separated due to loosening, or having poor contact. When it is necessary to unplug the plug, apply pressure to the button 14 of the pressing control component 3. The two rotating locking components 8 will release the ground terminal of the plug, allowing the plug to be unplugged. This invention has a simple structure, low production and usage costs, is easy and convenient to operate, has a good anti-pull-out effect, effectively reduces the probability of accidents, and adopts a mechanical transmission locking mechanism, ensuring stable and reliable operation, reducing the likelihood of malfunctions and lowering maintenance costs.

[0030] Specifically, the socket core 13 and the cover plate 2 are integrally injection molded, and the socket core 13, the cover plate 2, the pressing control component 3 and the power socket shell 1 are all made of plastic material.

[0031] In this embodiment, a rotating shaft 16 protrudes from the end face of the socket core 13. The rotating shaft 16 is located at the center of the live wire terminal 5, the neutral wire terminal 6, and the ground wire terminal 7. One end of each of the two rotating locking members 8 is rotatably connected to the rotating shaft 16. The two rotating locking members 8 are located between the two control posts 15 and are connected in series on the rotating shaft 16. In practical applications, the two rotating locking members 8 rotate around the central axis of the rotating shaft 16, moving closer to or further away from each other, which improves the rotational stability of the rotating locking members 8 and facilitates the assembly of the rotating locking members 8 with the socket core 13.

[0032] In this embodiment, the inner side of the control column 15 is provided with an opening inclined surface 17 and a locking vertical surface 18 from top to bottom; when the locking vertical surface 18 abuts against the middle of the rotating locking member 8, the two rotating locking members 8 move closer to each other; when the middle of the rotating locking member 8 corresponds to the opening inclined surface 17, the two rotating locking members 8 can open to each other.

[0033] In practical applications, when the reset drive 4 drives the press control 3 to reset and move to the initial state (highest position), the locking vertical surfaces 18 of the two control posts 15 respectively abut against the middle of the two rotating locking parts 8 and apply an inward force to the rotating locking parts 8, so that the two rotating locking parts 8 can lock the ground terminal of the plug to prevent it from being pulled out. When it is necessary to actively pull out the plug or plug it into the present invention, a pressing force is applied to the button 14 of the press control 3, causing the press control 3 to move down. As the press control 3 moves down, the opening slope 17 of the control post 15 will move down to correspond to the middle of the rotating locking part 8. At this time, the opening slope 17 of the two control posts 15 is flared to provide the two rotating locking parts 8 with a rotation space that keeps them away from each other. At this time, the plug can be easily pulled out of the present invention or easily plugged into the present invention.

[0034] In this embodiment, an abutment block 19 protrudes from the outer side of the middle portion of the rotating locking member 8. The abutment block 19 is used to abut against the locking vertical surface 18. This structural design facilitates the inward rotation of the rotating locking member 8 by the locking vertical surface 18 of the control column 15, thereby reducing the contact area between the two. Specifically, the free end of the abutment block 19 is provided with an arc surface, which abuts against the locking vertical surface 18, reducing wear.

[0035] In this embodiment, a limiting plate 20 is provided on the end face of the socket core 13. The limiting plate 20 is located on the side of the ground wire plug terminal 7 away from the rotating shaft 16. The two end faces of the limiting plate 20 are used to abut against the other ends of the two rotating locking members 8. The limiting plate 20 is used to limit the extreme position of the two rotating locking members 8 approaching each other. When the locking vertical surfaces 18 of the two control posts 15 abut against the abutting blocks 19 of the two rotating locking members 8 respectively to provide locking force to the two rotating locking members 8, the free ends of the two rotating locking members 8 abut against the two end faces of the limiting plate 20 respectively to limit the extreme position of the two rotating locking members 8 approaching each other, thereby ensuring that the locking force of the two rotating locking members 8 locking the ground wire terminal of the plug is constant, and preventing the two rotating locking members 8 from approaching each other too much and causing the locking force to be too large or to fail.

[0036] Specifically, the limiting plate 20 includes two limiting blocks, which protrude from the end face of the socket core 13. The two limiting blocks are used to abut against the other ends of the two rotating locking members 8, and the two limiting blocks are used to limit the extreme position of the two rotating locking members 8 approaching each other.

[0037] In this embodiment, a spring piece 21 is bent on the inner side of the middle of the rotating locking member 8. The spring piece 21 can undergo restorable elastic deformation when compressed. When the two rotating locking members 8 lock the ground terminal of the plug, the spring pieces 21 on the two rotating locking members 8 will undergo elastic deformation and elastically press the ground terminal of the plug. This not only ensures the locking force, but also, because the spring piece 21 has a certain elasticity, it plays a buffering role for the rotating locking member 8, avoiding hard impact collision between the rotating locking member 8 and the ground terminal of the plug, reducing noise. Furthermore, when the button 14 of the pressing control member 3 is pressed, and the ground terminal of the plug is pulled upward from the ground plug terminal 7, as the ground terminal of the plug moves upward, the spring piece 21 will elastically recover, and this elastic force will push the rotating locking member 8 to rotate outward, so that the two rotating locking members 8 rotate away from each other, which is conducive to the smooth removal of the ground terminal of the plug from this utility model.

[0038] In this embodiment, the cover plate 2 has a protruding guide post 22, and the button 14 is disposed on the end face of the guide post 22. The back of the power socket housing 1 has a recessed guide hole 23, and the front of the power socket housing 1 has a through hole 24 communicating with the guide hole 23. The guide post 22 is slidably connected to the guide hole 23, and the button 14 slides through the through hole 24. During the lifting and lowering process of the pressing control component 3, the guide post 22 and the guide hole 23 slide to cooperate, thereby improving the lifting stability and positional accuracy of the pressing control component 3, and facilitating the assembly of the pressing control component 3 between the cover plate 2 and the power socket housing 1.

[0039] In this embodiment, the bottom surface of the guide post 22 is recessed with a mounting cavity 25. One end of the reset drive 4 is mounted on the cover plate 2, and the other end of the reset drive 4 is mounted inside the mounting cavity 25. Furthermore, the reset drive 4 is a spring, and the cover plate 2 has a protruding guide rod 30. The spring is sleeved on the outside of the guide rod 30, and the guide rod 30 can extend into the mounting cavity 25. This structural design makes the structure between the reset drive 4, the pressing control 3, and the cover plate 2 compact, and the mounting cavity 25 and the guide rod 30 play a role in positioning and guiding the reset drive 4, improving the working stability of the reset drive 4.

[0040] In this embodiment, a protective partition 26 protrudes from the end face of the socket core 13. The live wire terminal 5 and the ground wire terminal 7 are located on the same side of the protective partition 26, while the rotating shaft 16 and two rotating locking members 8 are located on the other side of the protective partition 26. The protective partition 26 separates the two rotating locking members 8 from the live wire terminal 5 and the ground wire terminal 7. This structural design, by separating the two rotating locking members 8 from the live wire terminal 5 and the ground wire terminal 7 through the protective partition 26, prevents the ground wire terminal from becoming energized due to an electric arc when the plug is inserted, thus providing safety protection and improving the safety performance during use.

[0041] Specifically, the front of the power socket housing 1 is recessed with an annular slot 27, and the live wire hole 10, neutral wire hole 11, and ground wire hole 12 are all located within the area of ​​the annular slot 27. When the plug is inserted into this utility model, the annular sleeve of the plug is inserted into the annular slot 27 of the power socket housing 1, which not only further improves the firmness of the plug's insertion into this utility model, but also achieves a better waterproof effect.

[0042] Specifically, the cover plate 2 is snapped into the power socket housing 1; preferably, the cover plate 2 is snapped into the power socket housing 1 via a snap-fit ​​assembly 28, specifically, the snap-fit ​​assembly 28 consists of a snap and a slot. This structural design facilitates the secure assembly of the cover plate 2 and the power socket housing 1, and makes disassembly and maintenance convenient.

[0043] Specifically, the side wall of the power socket housing 1 is provided with an elastic buckle 29. When the power socket housing 1 is assembled with the external structure, the elastic buckle 29 is elastically engaged with the inner cavity wall of the external structure, thereby improving the stability of the power socket housing 1 and the present invention assembled in the inner cavity of the external structure.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
