Description

Technical Field

[0001] The present invention relates to the technical field of sockets, and particularly to an anti-pulling-out power socket. Background Art

[0002] The connection between a plug and a socket is the most common way to power on electrical appliances in daily life. Since the socket is often fixed in a certain position such as on a wall, the electrical appliance is connected to the socket and the plug by wires, and these wires are often exposed outside. In daily life, situations such as accidentally pulling the wires or even kicking the wires often occur. At this time, the plug will be instantly pulled out of the socket, resulting in the power-off of the electrical appliance; in addition, many electrical appliances in life or many machines in industrial production are used in a vibrating environment. Under strong vibration conditions, the connection between the plug and the socket is very likely to become detached, resulting in the power-off of the electrical appliance.

[0003] In the existing patent, the Chinese patent document with the application number 201910594983.9 discloses: a safety anti-loosening socket, including a socket and a plug. The plug consists of a base body and two connectors embedded at one end of the base body. The socket includes a square shell. The inner wall of the shell is fixedly connected with clamping spring pieces at the corresponding positions of the connectors. The outer wall of the shell is provided with jacks adapted to the connectors. A loosening prevention pressing mechanism is provided in the middle of the two clamping spring pieces; the loosening prevention 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 with a bearing plate with a concave shape on the side. The concave surface of the bearing plate is in the same plane as the clamping spring pieces. A sealed expansion airbag is provided in the middle of the upper end of the bearing plate. The expansion airbag is filled with a thermo-expandable and contractible medium. An electric heating wire is horizontally arranged in the expansion airbag. Both the left and right ends of the expansion airbag are fixedly connected with pressing plates. The end of the pressing plate is fixedly connected with a pressing plate having the same shape as the outside of the clamping spring piece. Guide balls are installed at the front and rear folding corners of the expansion airbag. The guide balls are in rolling connection with the inner walls on both sides of the bearing plate. A converter is fixedly connected to the side of the bearing plate away from the connecting rod. A self-resetting push-button switch is fixedly installed on the shell between the two jacks; the two clamping spring pieces, the electric heating wire, the converter and the self-resetting push-button switch are connected in series to form a heating and expanding circuit. This patent document heats the thermo-expandable and contractible medium in the expansion airbag through the electric heating wire, so that the expansion airbag expands to drive the movement of the pressing plate. It requires a large number of electrical components and the heating and expanding circuit to cooperate with each other. The structure is complex, and the production and use costs are high. The electronic control method is prone to failure, increasing the maintenance cost. Moreover, it takes a certain amount of time for the electric heating wire to heat the thermo-expandable and contractible medium and for the thermo-expandable and contractible medium to cool down. The reaction time is long and not sensitive enough, making it impossible to quickly lock or loosen the plug.

[0027] For the convenience of those skilled in the art to understand, the present invention will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the implementation manners does not limit the present invention.

[0028] Such as Figures 1 to 7As shown in the figure, a power socket that prevents pulling out provided by the present invention includes a power socket housing 1, a cover plate 2, a pressing control member 3, a reset driving member 4, a live wire plugging terminal 5, a neutral wire plugging terminal 6, a ground wire plugging terminal 7, and two rotating locking members 8. A cavity 9 is recessed on the back surface of the power socket housing 1. A live wire hole 10, a neutral wire hole 11, and a ground wire hole 12 that communicate with the cavity 9 are opened on the front surface of the power socket housing 1. The cover plate 2 is installed on the power socket housing 1 and covers the opening of the cavity 9. A socket core 13 protrudes from the cover plate 2. The socket core 13 is accommodated in the cavity 9. The live wire plugging terminal 5, the neutral wire plugging terminal 6, and the ground wire plugging terminal 7 are distributed in a triangular shape and embedded in the socket core 13. The wiring ends of the live wire plugging terminal 5, the neutral wire plugging terminal 6, and the ground wire plugging terminal 7 all extend outside the cover plate 2 and are respectively connected to the wires of the circuit. The live wire plugging terminal 5, the neutral wire plugging terminal 6, and the ground wire plugging terminal 7 respectively communicate with the live wire hole 10, the neutral wire hole 11, and the ground wire hole 12. The two rotating locking members 8 are rotatably arranged on the end face of the socket core 13 and are located in the cavity 9. The two rotating locking members 8 are located between the ground wire plugging terminal 7 and the ground wire hole 12. The two rotating locking members 8 are arranged in a semi-surrounding manner around the ground wire plugging terminal 7. The pressing control member 3 is arranged to move up and down on the power socket housing 1. The pressing control member 3 is connected to the cover plate 2 via the reset driving member 4. The reset driving member 4 is used to drive the pressing control member 3 to reset and move. The pressing control member 3 is provided with a button 14 and two control columns 15. The button 14 can extend outside the front surface of the power socket housing 1. The two control columns 15 are arranged to move up and down in the cavity 9. The two control columns 15 are used to control the two rotating locking members 8 to approach or separate from each other.

[0029] In practical applications, when the anti-pull-out power socket is in its normal state, the pressing control member 3 is at its highest position under the reset driving action of the reset driving member 4. The button 14 of the pressing control member 3 extends out of the front of the power socket housing 1. The two control columns 15 of the pressing control member 3 apply an inward pressure (locking force) to the two rotating locking members 8, causing the two rotating locking members 8 to rotate towards each other. When it is necessary to insert a plug into the anti-pull-out power socket, a pressing force is applied to the button 14 of the pressing control member 3, causing the pressing control member 3 to move downward until it reaches its lowest position. At this time, the two control columns 15 of the pressing control member 3 release the locking force on the two rotating locking members 8, and the two rotating locking members 8 can open. At the same time, the live wire terminal, neutral wire terminal, and ground wire terminal of the plug are respectively aligned with the live wire hole 10, neutral wire hole 11, and ground wire hole 12 and inserted until the live wire terminal, neutral wire terminal, and ground wire terminal of the plug are completely inserted into the live wire plugging terminal 5, neutral wire plugging terminal 6, and ground wire plugging terminal 7 and electrically connected, with the ground wire terminal located between the two rotating locking members in the open state. At this time, only by releasing the pressing force on the button 14 of the pressing control member 3, the reset driving member 4 drives the pressing control member 3 to move upward and reset, causing the button 14 of the pressing control member 3 to reset upward, and the two control columns 15 of the pressing control member 3 apply an inward locking force to the two rotating locking members 8, causing the two rotating locking members 8 to rotate closer to each other and lock the ground wire terminal of the plug in the ground wire plugging terminal 7, so that the plug can be firmly plugged and used with the present invention, preventing problems such as accidental unplugging, separation due to loosening, or poor contact of the plug. When it is necessary to unplug the plug from the present invention, a pressing force is applied to the button 14 of the pressing control member 3, and the two rotating locking members 8 release the ground wire terminal of the plug, and the plug can be unplugged from the present invention. The structure of the present invention is simple, the production and use costs are low, the operation is easy and convenient, the anti-pull-out effect is good, effectively reducing the occurrence probability of accidents, and using mechanical transmission locking, the work is stable and reliable, not easily prone to failure, and reducing the maintenance cost.

[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 member 3, and the power socket housing 1 are all made of plastic materials.

[0031] In this embodiment, a rotating shaft 16 is convexly provided on the end face of the socket core 13. The rotating shaft 16 is located at the central position of the live wire plugging terminal 5, the neutral wire plugging terminal 6, and the ground wire plugging terminal 7. One end 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 columns 15, and the two rotating locking members 8 are serially arranged on the rotating shaft 16. In practical applications, the two rotating locking members 8 rotate closer to or away from each other around the central axis of the rotating shaft 16, improving the rotational stability of the rotating locking members 8 and facilitating the assembly of the rotating locking members 8 with the socket core 13.

[0032] In this embodiment, an opening inclined surface 17 and a locking vertical surface 18 are sequentially arranged on the inner side surface of the control column 15 from top to bottom; when the locking vertical surface 18 abuts against the middle part of the rotating locking member 8, the two rotating locking members 8 approach each other; when the middle part of the rotating locking member 8 corresponds to the opening inclined surface 17, the two rotating locking members 8 can be opened from each other.

[0033] In practical applications, when the reset driving member 4 drives the pressing control member 3 to reset and move to the starting state (highest position), the locking vertical surfaces 18 of the two control columns 15 respectively abut against the middle parts of the two rotating locking members 8 and apply an inward acting force to the rotating locking members 8, so that the two rotating locking members 8 can lock the ground wire terminal of the plug, so as to achieve the effect of preventing pulling out; when it is necessary to actively pull out the plug or insert the plug for use in the present invention, a pressing force is applied to the button 14 of the pressing control member 3, so that the pressing control member 3 moves downward. As the pressing control member 3 moves downward, the opening inclined surface 17 of the control column 15 will move downward to correspond to the middle part of the rotating locking member 8. At this time, the opening inclined surfaces 17 of the two control columns 15 are in a flared shape, so as to provide a rotating space for the two rotating locking members 8 to rotate away from each other. At this time, the plug can be easily pulled out of the present invention or inserted into the present invention easily.

[0034] In this embodiment, a contact block 19 is convexly provided on the outer side of the middle part of the rotating locking member 8, and the contact block 19 is used to abut against the locking vertical surface 18. This structural design facilitates the locking vertical surface 18 of the control column 15 to abut against the rotating locking member 8 and rotate inward, reducing the contact area between the two; specifically, an arc surface is provided at the free end of the contact block 19, and the arc surface abuts against the locking vertical surface 18 to reduce wear.

[0035] In this embodiment, a limiting plate 20 is provided on the end surface of the socket core 13. The limiting plate 20 is located on the side of the ground wire insertion terminal 7 away from the rotating shaft 16. The two end surfaces of the limiting plate 20 are used to abut against the other ends of the two rotating locking members 8, and the limiting plate 20 is used to limit the extreme limit of the two rotating locking members 8 approaching each other. When the locking vertical surfaces 18 of the two control columns 15 respectively abut against the contact blocks 19 of the two rotating locking members 8 to provide a locking force to the two rotating locking members 8, the free ends of the two rotating locking members 8 respectively abut against the two end surfaces of the limiting plate 20 to limit the extreme limit of the two rotating locking members 8 rotating close to each other, so as to ensure that the locking force for the two rotating locking members 8 to lock the ground wire terminal of the plug is constant, and prevent the two rotating locking members 8 from rotating too close to each other and the locking force being too large or ineffective.

[0036] Specifically, the limiting plate 20 includes two limiting blocks, and the two limiting blocks are convexly provided from the end surface 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 limit of the two rotating locking members 8 approaching each other.

[0037] In this embodiment, an elastic sheet 21 is bent and arranged on the inner side of the middle part of the rotating locking member 8. The elastic sheet 21 can undergo recoverable elastic deformation when being extruded. When the two rotating locking members 8 lock the ground wire terminal of the plug, the elastic sheets 21 on the two rotating locking members 8 will undergo elastic deformation and elastically press the ground wire terminal of the plug, which not only ensures the locking force, but also plays a buffering role for the rotating locking member 8 because the elastic sheet 21 has certain elasticity, avoiding hard impact collision between the rotating locking member 8 and the ground wire terminal of the plug, reducing noise. And when a pressing force is applied to the button 14 of the pressing control member 3 and the ground wire terminal of the plug is pulled out upward from the ground wire insertion terminal 7, as the ground wire terminal of the plug moves upward, the elastic sheet 21 will undergo elastic recovery, 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 wire terminal of the plug from the present invention.

[0038] In this embodiment, the cover plate 2 is provided with a guide post 22 protruding therefrom, the button 14 is arranged on the end face of the guide post 22, a guide hole 23 is recessed on the back surface of the power socket housing 1, a through hole 24 communicating with the guide hole 23 is opened on the front surface of the power socket housing 1, the guide post 22 is slidably connected with the guide hole 23, and the button 14 slidably penetrates through the through hole 24. During the lifting process of the pressing control member 3, the guide post 22 and the guide hole 23 are slidably matched, so as to improve the lifting stability and position accuracy of the pressing control member 3, and it is convenient to assemble the pressing control member 3 between the cover plate 2 and the power socket housing 1.

[0039] In this embodiment, an installation cavity 25 is recessed on the bottom surface of the guide post 22, one end of the reset driving member 4 is installed on the cover plate 2, and the other end of the reset driving member 4 is installed in the installation cavity 25; further, the reset driving member 4 is a spring, the cover plate 2 is provided with a guide rod 30 protruding therefrom, the spring is sleeved outside the guide rod 30, and the guide rod 30 can extend into the installation cavity 25. This structural design makes the structure among the reset driving member 4, the pressing control member 3 and the cover plate 2 compact, and the installation cavity 25 and the guide rod 30 play a role in positioning and guiding the reset driving member 4, improving the working stability of the reset driving member 4.

[0040] In this embodiment, a protective partition 26 is convexly provided on the end face of the socket core 13. The live wire insertion terminal 5 and the ground wire insertion terminal 7 are located on the same side of the protective partition 26, the rotating shaft 16 and the two rotating locking members 8 are located on the other side of the protective partition 26, and the protective partition 26 is used to separate the two rotating locking members 8 from the live wire insertion terminal 5 and the ground wire insertion terminal 7. This structural design separates the two rotating locking members 8 from the live wire insertion terminal 5 and the ground wire insertion terminal 7 through the protective partition 26, preventing the generation of electric arcs when inserting the plug and causing the ground wire terminal to be charged, playing a role in safety protection and improving the safety performance of use.

[0041] Specifically, a circular slot 27 is recessed on the front surface of the power socket housing 1, and the live wire hole 10, the neutral wire hole 11, and the ground wire hole 12 are all located within the area of the circular slot 27. When the plug is inserted into the present invention, the circular sleeve of the plug is inserted into the circular slot 27 of the power socket housing 1, which not only further improves the firmness of the plug inserted into the present invention, but also achieves a better waterproof effect.

[0042] Specifically, the cover plate 2 is snap-connected to the power socket housing 1; preferably, the cover plate 2 is snap-connected to the power socket housing 1 via a snap component 28. Specifically, the snap component 28 is composed of a snap and a slot. This structural design facilitates the stable assembly of the cover plate 2 and the power socket housing 1, and is convenient for disassembly, assembly, and maintenance.

[0043] Specifically, an elastic buckle 29 is provided on the side wall of the power socket housing 1. When the power socket housing 1 is assembled with an external structure, the elastic buckle 29 is elastically snap-connected to the inner cavity wall of the external structure, so as to improve the stability of the power socket housing 1 and the present invention assembled in the inner cavity of the external structure.

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

[0045] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
