Description

Technical Field

[0001] This utility model relates to the field of power socket technology, and more specifically, to a socket. Background Technology

[0002] In existing power distribution systems, traditional socket devices, as basic components for power transmission, are widely used for connecting and supplying power to various electrical appliances. However, their functional limitations are becoming increasingly apparent, and they cannot meet the current high standards for safe, stable, and intelligent operation.

[0003] First, traditional socket devices have significant shortcomings in overload protection mechanisms. Overload refers to a situation where the current in a circuit exceeds the rated value. If measures are not taken in time, it can easily lead to safety hazards such as overheating of wires, aging of insulation, and even fire. However, many traditional sockets lack efficient and reliable overload protection devices, failing to effectively prevent overload accidents and threatening the safety of users' lives and property. Second, the insertion and extraction force between traditional sockets and plugs is often weak, making them prone to accidental dislodgement due to slight external contact or the weight of the equipment itself. This not only affects the normal power supply to electrical appliances but may also lead to short circuits, equipment damage, and other consequences, seriously impacting the stability of the power system and the continuous operation of equipment. Furthermore, traditional sockets neglect the user's need for intuitive understanding of the working status. Users cannot immediately determine whether the socket is powered on or whether there is a fault, which not only increases operational inconvenience but also reduces overall safety and efficiency.

[0004] In summary, given the shortcomings of traditional socket devices in terms of overload protection, plugging / unplugging performance, and operating status indication, there is an urgent need for a new type of socket device to solve the problems existing in the current technology, improve the safety, stability, and intelligence level of the power distribution system, and meet the needs of modern homes and industrial sites for high-quality power access solutions.

A mounting hole is provided on the housing corresponding to the light guide post, and the light guide post is snapped into the mounting hole. One end of the neutral wire connecting copper rod is electrically connected to the indicator light circuit board, and the other end of the neutral wire connecting copper rod extends out of the housing and is connected to the neutral wire adapter copper strip. One end of the neutral wire adapter copper strip is connected to the neutral wire input copper strip.

[0009] Optionally, the locking assembly includes a card and an adjusting block. The card is disposed inside the grounding socket and above the grounding sleeve. The card has a through hole that is vertically connected to the grounding socket. The two ends of the card are a first end and a second end. The first end is movably connected to the inner wall of the grounding socket, and the second end extends out of the grounding socket and is connected to the adjusting block. The adjusting block can move up and down relative to the housing. When the grounding pin of the three-prong plug is inserted into the grounding socket, the grounding pin passes through the through hole and connects to the grounding sleeve. The card is tilted relative to the central axis of the grounding socket so that the through hole engages with the grounding pin. When the grounding pin is pulled out of the grounding socket, the adjusting block moves relative to the housing and drives the card to rotate around the first end, making the card perpendicular to the central axis of the grounding socket, thereby releasing the engagement between the through hole and the grounding pin.

[0010] Optionally, a slot is provided on one side of the adjustment block, the second end extends out of the grounding socket and is inserted into the slot, the upper end of the side of the adjustment block away from the slot extends out of the housing to form a button, and an elastic element is connected between the lower end of the adjustment block and the bottom of the housing.

[0011] Optionally, the bottom of the housing is provided with a guide post corresponding to the elastic element, the lower end of the adjusting block is provided with an upwardly extending mounting groove, one end of the elastic element is sleeved on the outer periphery of the guide post, and the other end of the elastic element is connected in the mounting groove.

[0012] Optionally, a slot is provided on the inner sidewall of the grounding socket, the slot is located at the upper end of the grounding sleeve, and the first end is inserted into the slot.

[0013] Optionally, the grounding socket includes a base plate, with clamping springs connected to both ends of the base plate. A clamping gap is formed between the two clamping springs for inserting a grounding pin. The lower end of the base plate extends out of the grounding socket and is provided with a wiring hole, and the grounding input copper strip is inserted into the wiring hole.

[0015] Optionally, the outer peripheral sidewall of the housing is provided with a plurality of latches at intervals, the latches being used to connect with the housing of the power distribution unit.

[0016] The beneficial effects of this socket are as follows: The socket includes a housing for installing and protecting internal components. Three input copper strips are connected to one side of the housing: a ground input copper strip, a neutral input copper strip, and a live input copper strip. The housing has corresponding sockets for a three-prong plug: a ground socket, a live socket, and a neutral socket. Each socket has a corresponding sleeve, the lower end of which extends out of the socket and connects to the corresponding input copper strip. The ground sleeve in the ground socket, the neutral sleeve in the neutral socket, and the live sleeve in the live socket are responsible for connecting the ground pin, neutral pin, and live pin of the three-prong plug, respectively. A fuse assembly is connected between the lower end of the live sleeve and the live input copper strip.

[0017] This invention, by introducing a fuse assembly, enables the socket to automatically cut off the circuit in the event of an overload, effectively preventing safety hazards such as wire overheating, insulation aging, and even fire. Simultaneously, a locking assembly ensures the plug will not accidentally detach due to external force, reducing the risk of short circuits and equipment damage, thus improving safety. Furthermore, the locking assembly improves insertion and removal performance, ensuring stable power supply to electrical devices and preventing the stability of the power system from being affected by a detached plug. The indicator light assembly provides users with a visual indication of the socket's operating status, allowing them to easily understand whether the socket is powered on or if there are any faults, improving operational convenience and safety. Therefore, this invention, by introducing a fuse assembly, locking assembly, and indicator light assembly, effectively improves the safety, stability, and intelligence of the power distribution system, addressing the shortcomings of traditional sockets in overload protection, insertion and removal performance, and operating status indication, meeting the needs of modern homes and industrial sites for high-quality power access solutions.

[0032] like Figure 1 , Figure 2 As shown, an embodiment of this utility model provides a socket, including a housing 1. A ground wire input copper strip 5, a neutral wire input copper strip 6, and a live wire input copper strip 7 are connected to one side of the housing 1. The housing 1 has a ground wire socket 11, a live wire socket 12, and a neutral wire socket 13 for inserting a three-prong plug. A ground wire sleeve 14 is provided inside the ground wire socket 11, with its lower end extending out of the ground wire socket 11 and connected to the ground wire input copper strip 5. A neutral wire sleeve 15 is provided inside the neutral wire socket 13, with its lower end extending out of the socket. The neutral wire socket 13 is connected to the neutral wire input copper strip 6. The live wire socket 12 is provided with a live wire sleeve 16. The lower end of the live wire sleeve 16 extends out of the live wire socket 12 and is connected to the live wire input copper strip 7 with a fuse assembly 2. The ground wire sleeve 14 is provided with a locking assembly 3. The locking assembly 3 is used to lock and unlock the grounding pin of the three-prong plug inserted into the ground wire sleeve 14. The housing 1 is also provided with an indicator light assembly 4. The indicator light assembly 4 is electrically connected between the neutral wire input copper strip 6 and the lower end of the live wire sleeve 16.

[0033] Specifically, the socket housing 1 has a ground wire input copper strip 5, a neutral wire input copper strip 6, and a live wire input copper strip 7 connected to one side for receiving electrical energy from the power system. The housing 1 has ground wire sockets 11, live wire sockets 12, and neutral wire sockets 13 corresponding to the three-prong plug. These sockets correspond to the grounding pin, live pin, and neutral pin of the three-prong plug, respectively. Each socket has a ground wire sleeve 14, a live wire sleeve 16, and a neutral wire sleeve 15 for electrical connection with the pins. The lower end of each sleeve connects to the corresponding input copper strip, forming a power transmission path. A fuse assembly 2 connects the live wire sleeve 16 in the live wire socket 12 to the live wire input copper strip 7. The fuse assembly 2 has a fuse 22. When the current in the circuit exceeds the rated value of the fuse assembly 2, the fuse 22 will automatically melt and disconnect the circuit, thus preventing overload-induced wire overheating, insulation aging, and even fire hazards. A locking component 3 is provided at the grounding socket 14, which can firmly lock the grounding pin of the three-prong plug inserted into the grounding socket 14, preventing it from accidentally falling off due to slight external contact or the weight of the equipment itself, ensuring a stable power supply to the electrical equipment, and avoiding consequences such as short circuits and equipment damage. An indicator light component 4 is provided inside the housing 1. The indicator light component 4 is connected between the neutral wire input copper strip 6 and the lower end of the live wire socket 16. When the socket is powered on, the indicator light will light up, providing users with a direct indication of the socket's working status. This helps users determine whether the socket is powered on, whether there is a fault, and other key information, improving the safety and efficiency of operation.

[0034] In this embodiment, the housing 1 is provided with six sets of three-hole socket assemblies arranged in a linear pattern, and each set of three-hole socket assemblies can accommodate a three-prong plug. A parallel ground wire input copper strip 5, a neutral wire input copper strip 6, and a live wire input copper strip 7 are connected to one side of the housing 1, and the extension direction of each input copper strip is consistent with the arrangement direction of the six sets of three-hole socket assemblies. Each three-hole socket assembly includes a ground wire socket 11, a live wire socket 12, and a neutral wire socket 13, which are disposed on the housing 1 and pass through both sides of the housing 1. Each three-hole socket assembly also includes a ground wire sleeve 14 disposed in the ground wire socket 11, a live wire sleeve 16 disposed in the live wire socket 12, and a neutral wire sleeve 15 disposed in the neutral wire socket 13. The lower end of the ground wire sleeve 14 extends out of the ground wire socket 11 and is connected to the ground wire input copper strip 5. The lower end of the neutral wire sleeve 15 extends out of the neutral wire socket 13 and is connected to the neutral wire input copper strip 6. Each three-hole socket assembly also includes a fuse assembly 2 and an indicator light assembly 4. The fuse assembly 2 is connected between the lower end of the live wire sleeve 16 and the live wire input copper strip 7. The indicator light assembly 4 is connected between the neutral wire input copper strip 6 and the lower end of the live wire sleeve 16. Overload protection is achieved through fuse assembly 2, effectively preventing safety hazards such as fires caused by overload. Meanwhile, locking assembly 3 ensures a stable plug connection, preventing short circuits and equipment damage caused by plug detachment, thus improving safety. Furthermore, locking assembly 3 improves plug-in / plug-out performance, ensuring stable power supply to electrical equipment, contributing to the stability of the power system and enhancing the continuous operation of equipment. In addition, indicator light assembly 4 provides users with intuitive indication of the socket's operating status, simplifying the operation process, improving overall convenience and safety, and enhancing the level of intelligence.

[0035] Optionally, such as Figure 3 As shown, the fuse assembly 2 includes a live wire input copper piece 21, a fuse 22, a live wire output copper piece 23, and a live wire connecting copper strip 24. The live wire input copper piece 21 extends out of the housing 1 and is connected to the live wire input copper strip 7. The live wire output copper piece 23 extends out of the housing 1 and is connected to the lower end of the live wire socket 16 through the live wire connecting copper strip 24. The fuse 22 is connected between the live wire input copper piece 21 and the live wire output copper piece 23.

[0036] Specifically, the live wire input copper strip 21 extends out of the housing 1 and connects to the live wire input copper strip 7 to receive live wire power from the power system. Its material and size must meet the requirements of current transmission to ensure the stability and safety of the circuit. The live wire output copper strip 23 extends out of the housing 1 and connects to the lower end of the live wire socket 16 via the live wire connecting copper strip 24, forming a power supply path to electrical equipment. It must ensure a good electrical connection with the plug of the electrical equipment to guarantee stable current transmission. The live wire connecting copper strip 24 serves as a bridge connecting the live wire output copper strip 23 and the live wire socket 16. Its material and size must meet the requirements of current transmission to ensure the stability and safety of the circuit. At the same time, the live wire connecting copper strip 24 must also consider the needs of easy installation and maintenance. Fuse 22 is connected between the live wire input copper piece 21 and the live wire output copper piece 23. As a weak point in the circuit, when the current in the circuit exceeds the rated current of fuse 22, the fuse wire inside fuse 22 will quickly melt, severing the circuit connection between the live wire input copper piece 21 and the live wire output copper piece 23. Thus, even if a fault occurs inside the electrical equipment or socket causing an abnormally high current, it will not damage the entire power system. The rated current value of fuse 22 can be selected according to actual needs to adapt to different application scenarios. After fuse 22 melts, replacing it with a new fuse 22 will restore power to the circuit.

[0037] In this optional embodiment, when the socket is powered on, the live wire input copper piece 21 receives electrical energy from the live wire input copper strip 7 and transmits it to the live wire output copper piece 23 through the fuse 22. The live wire output copper piece 23 is then connected to the lower end of the live wire socket 16 through the live wire connecting copper strip 24, thereby transmitting electrical energy to the three-prong plug inserted into the socket. The fuse 22 is the core component of the fuse assembly 2. It is filled with a fusible alloy. When the current in the circuit exceeds the rated value of the fuse 22, the fusible alloy will heat up rapidly and melt, thereby cutting off the circuit connection between the live wire input copper piece 21 and the live wire output copper piece 23. The live wire transmission path of the socket is cut off, preventing safety accidents caused by overload. The fuse assembly 2 enables the socket to quickly cut off the circuit under overload conditions, preventing safety hazards such as wire overheating, insulation aging, and even fire, greatly improving the safety performance of the socket. When fuse 22 blows, the user can restore the socket to normal use by simply replacing the fuse 22 between the live wire input copper piece 21 and the live wire output copper piece 23, reducing maintenance costs. The fuse assembly 2 can be selected according to different rated current values ​​to adapt to the power needs of different electrical appliances, making the socket have a wider range of applications.

[0038] Optionally, such as Figure 1 , Figure 4The indicator light assembly 4 includes an indicator light circuit board 41, a neutral wire adapter copper strip 42, and a neutral wire connecting copper rod 43. The indicator light circuit board 41 is connected in parallel with the fuse 22. An LED light 44 is provided on the indicator light circuit board 41. A light guide post 45 is provided at the upper end of the LED light 44. A mounting hole 17 is provided on the housing 1 corresponding to the light guide post 45. The light guide post 45 is snapped into the mounting hole 17. One end of the neutral wire connecting copper rod 43 is electrically connected to the indicator light circuit board 41. The other end of the neutral wire connecting copper rod 43 extends out of the housing 1 and is connected to the neutral wire adapter copper strip 42. One end of the neutral wire adapter copper strip 42 is connected to the neutral wire input copper strip 6.

[0039] Specifically, one end of the neutral wire adapter copper strip 42 is connected to the neutral wire input copper strip 6, and the other end is electrically connected to the indicator circuit board 41 through the neutral wire connecting copper rod 43. The neutral wire adapter copper strip 42 and the neutral wire connecting copper rod 43 together form the neutral wire circuit of the indicator assembly 4. At the same time, the two ends of the indicator circuit board 41 are connected to the two ends of the fuse 22 through copper sheets (that is, the indicator circuit board 41 is connected between the live wire input copper sheet 21 and the live wire output copper sheet 23, and is connected in parallel with the fuse 22). When the socket is powered on, the current passes through the live wire input copper strip 7, the live wire input copper sheet 21, the LED light 44 on the indicator circuit board 41, the neutral wire connecting copper rod 43, the neutral wire adapter copper strip 42, and the neutral wire input copper strip 6 to form a current loop. When the socket is powered on, the LED 44 on the indicator circuit board 41 receives power and emits light. As the light-emitting element of the indicator assembly 4, the LED 44's light is guided to the outside of the housing 1 through the light guide post 45. The light guide post 45 ensures that the light from the LED 44 illuminates the outside of the housing 1 evenly and brightly, improving the clarity of the indication. The housing 1 has mounting holes 17 corresponding to the light guide post 45. The light guide post 45 is fixed by snapping into the mounting holes 17, ensuring both the stability of the light guide post 45 and allowing the light to be smoothly guided to the outside of the housing 1. When the socket is powered off, the LED 44 turns off, indicating to the user that the socket is off.

[0040] In this optional embodiment, current flows through the live wire input copper strip 7, the live wire input copper sheet 21, the LED 44 on the indicator circuit board 41, the neutral wire connecting copper rod 43, the neutral wire adapter copper strip 42, and the neutral wire input copper strip 6 to form an electrical circuit. When the socket is powered on, the LED 44 on the indicator circuit board 41 receives power and emits light, which is guided to the outside of the housing 1 through the light guide post 45, thereby indicating the working status of the socket. The indicator light assembly 4 allows the user to intuitively understand the working status of the socket, improving the convenience and safety of use. When the socket is powered on, the LED 44 lights up to indicate that the socket is in working condition; when the socket is powered off, the LED 44 goes out to indicate that the socket is turned off.

[0041] Optionally, such as Figure 5As shown, the locking assembly 3 includes a card 31 and an adjusting block 32. The card 31 is disposed inside the grounding socket 11 and above the grounding sleeve 14. The card 31 has a through hole 311 that is vertically connected to the grounding socket 11. The two ends of the card 31 are a first end 312 and a second end 313. The first end 312 is movably connected to the inner wall of the grounding socket 11, and the second end 313 extends out of the grounding socket 11 and is connected to the adjusting block 32. The adjusting block 32 can move vertically relative to the housing 1. When the grounding pin of the plug is inserted into the grounding socket 11, the grounding pin passes through the insertion hole 311 and connects to the grounding sleeve 14. The clip 31 is tilted relative to the central axis of the grounding socket 11 so that the insertion hole 311 engages with the grounding pin. When the grounding pin is pulled out of the grounding socket 11, the adjusting block 32 moves relative to the housing 1 and drives the clip 31 to rotate around the first end 312, so that the clip 31 is perpendicular to the central axis of the grounding socket 11, thereby releasing the engagement between the insertion hole 311 and the grounding pin.

[0042] Understandably, when the card 31 is tilted relative to the central axis of the grounding socket 11, the central axis of the insertion hole 311 is tilted relative to the central axis of the grounding socket 11, and the grounding pin of the three-prong plug is parallel to the central axis of the grounding socket 11. Therefore, the insertion hole 311 can engage with the grounding pin. When the card 31 is perpendicular to the central axis of the grounding socket 11, that is, the central axis of the insertion hole 311 is parallel to the central axis of the grounding socket 11, the insertion hole 311 can disengage from the grounding pin, that is, the grounding pin can be smoothly pulled out from the insertion hole 311.

[0043] Specifically, a grounding sleeve 14 is provided inside the grounding socket 11 for connecting to the grounding pin of the three-prong plug to ensure safe grounding of the circuit. Meanwhile, a card 31 is provided above the grounding socket 11, with a through hole 311 that extends vertically through the grounding socket 11, allowing the grounding pin to pass through and connect to the grounding sleeve 14. The two ends of the card 31 are a first end 312 and a second end 313. The first end 312 is rotatably connected to the inner wall of the grounding socket 11, allowing the card 31 to rotate around the first end 312. This allows the card 31 to tilt and reset accordingly based on the insertion and removal of the grounding pin. The card 31 is one of the key components for achieving the self-locking function; it tilts and locks itself when the grounding pin is inserted. The second end 313 of the card 31 extends out of the grounding socket 11 and is connected to an adjusting block 32. The adjusting block 32 can move up and down relative to the housing 1. By moving the adjusting block 32, the card 31 can rotate around the first end 312, thereby realizing the self-locking or unlocking function of the card 31. The adjusting block 32 is a bridge connecting the card 31 and the external operating components. The user can change the tilt state of the card 31 by moving the adjusting block 32 up and down, thereby unlocking the plug. The adjusting block 32 should be easy for the user to operate and have a certain degree of stability and durability.

[0044] In this optional embodiment, the initial state of the card 31 can be an inclined state, that is, the card 31 is inclined relative to the central axis of the grounding socket 11, and the first end 312 and the second end 313 of the card 31 are not on the same horizontal line. When the grounding pin of the three-prong plug is inserted into the grounding socket 11, the grounding pin passes through the insertion hole 311 of the card 31 and connects to the grounding sleeve 14. At this time, the card 31 is inclined relative to the central axis of the grounding socket 11. This inclination causes a certain locking force between the insertion hole 311 and the grounding pin, thereby locking the grounding pin. When it is necessary to pull the grounding pin out of the grounding socket 11, the adjusting block 32 moves relative to the housing 1, causing the card 31 to rotate around its first end 312, so that the card 31 becomes perpendicular to the central axis of the grounding socket 11, thereby reducing or eliminating the locking force between the insertion hole 311 and the grounding pin, so that the grounding pin can be easily pulled out. This embodiment, through the tilting of the card 31 and the movement of the adjusting block 32, ensures that the grounding pin is stably locked during insertion, preventing poor electrical connection or electric shock risk due to loosening. Simultaneously, the locking state can be easily released during removal, avoiding damage or safety hazards caused by excessive force. Since the tilt and vertical position of the card 31 can be flexibly adjusted via the adjusting block 32, wear on the card 31 during insertion and removal is reduced, extending the service life of the locking assembly 3. In use, the user can easily lock and release the grounding pin by simply moving the adjusting block 32, without the need for additional tools or force, thus improving ease of use and comfort.

[0045] Optionally, such as Figure 1 , Figure 5 As shown, a slot 321 is provided on one side of the adjustment block 32, and the second end 313 extends out of the ground wire socket 11 and is inserted into the slot 321. The upper end of the side of the adjustment block 32 away from the slot 321 extends out of the housing 1 to form a button 322. An elastic element 33 is connected between the lower end of the adjustment block 32 and the bottom of the housing 1.

[0046] Specifically, the adjusting block 32 is roughly U-shaped, comprising two spaced-apart columnar structures. One columnar structure is close to the card 31 and has a slot 321 at its end, while the other columnar structure is away from the card 31 and its end extends out of the housing 1 to form a button 322. The slot 321 allows the second end 313 of the card 31 to be stably inserted therein, thus ensuring the reliability of the connection between the adjusting block 32 and the card 31. The engagement between the card 31 and the adjusting block 32 is simple and easy to implement, and effectively prevents the card 31 from shaking or falling off during movement. The button 322 extends out of the housing 1, forming an easy-to-operate interface. Users can simply press this button 322 to move the adjusting block 32 up and down, realizing the self-locking and unlocking functions of the socket. The shape, size, and position of the button 322 can be designed according to actual needs to meet the usage habits of different users. The elastic element 33 (such as a spring) is connected between the lower end of the adjusting block 32 and the bottom of the housing 1, serving as a reset and buffer. This not only makes the adjusting block 32 more stable during movement but also allows it to automatically return to its original position after the user releases the button 322, preparing it for the next use. Simultaneously, the elastic element 33 can absorb and release energy, reducing impact and noise caused by operation.

[0047] In this optional embodiment, in the initial state, when the elastic element 33 is not compressed, the card 31 is tilted relative to the central axis of the grounding socket 11, and the second end 313 of the card 31 is closer to the insertion end of the grounding socket 11 than the first end 312. That is, the horizontal line where the second end 313 of the adjusting block 32 is connected to the card 31 is higher than the horizontal line where the first end 312 of the card 31 is. When the grounding pin of the three-prong plug is inserted into the grounding socket 11, the grounding pin will push the card 31 to rotate around the first end 312, causing the second end 313 of the card 31 and the adjusting block 32 to move downward and compress the elastic element 33 until the card 31 is perpendicular or nearly perpendicular to the central axis of the grounding socket 11. At this time, the grounding pin can pass smoothly through the insertion hole 311 of the card 31 and make an electrical connection with the grounding sleeve 14. After the grounding pin and grounding socket 14 are electrically connected, the pressure on the plug is released. The elastic element 33 then returns to its original shape, pushing the adjusting block 32 and the second end 313 of the card 31 upwards. This causes the card 31 to tilt again relative to the central axis of the grounding socket 11, allowing the insertion hole 311 of the card 31 to engage with the grounding pin, thus locking the grounding pin in place. When the plug needs to be removed, the user simply presses button 322, causing the adjusting block 32 to move downwards and compress the elastic element 33. Simultaneously, the adjusting block 32 rotates the card 31 around its first end 312 until the card 31 is perpendicular or nearly perpendicular to the central axis of the grounding socket 11. This releases the engagement of the grounding socket 11 with the card 31, allowing the grounding pin to be easily pulled out of the insertion hole 311 of the card 31. The user can then easily remove the plug from the grounding socket 11. When button 322 is released, the elastic element 33 pushes the adjusting block 32 back to its original position, preparing it for the next use. In this embodiment, button 322 allows users to operate the adjusting block 32 more conveniently without using tools or applying excessive force, greatly improving the ease of use of the socket. Furthermore, the cooperation between slot 321 and card 31, and the connection of the elastic element 3325, makes the adjusting block 32 more stable during movement, preventing shaking or misalignment, ensuring the socket's locking and unlocking mechanism operates stably and reliably. The resetting effect of the elastic element 33 allows the adjusting block 32 to automatically return to its original position after button 322 is released, avoiding safety hazards caused by misalignment of the adjusting block 32.

[0048] Optionally, such as Figure 5 , Figure 6 As shown, the bottom of the housing 1 is provided with a guide post 18 corresponding to the elastic member 33, and the lower end of the adjusting block 32 is provided with an upwardly extending mounting groove 323. One end of the elastic member 33 is sleeved on the outer periphery of the guide post 18, and the other end of the elastic member 33 is connected in the mounting groove 323.

[0049] Specifically, at the bottom of the housing 1, corresponding to the position of the elastic element 33, a guide post 18 is provided. The main function of the guide post 18 is to provide stable support and guidance, ensuring that the elastic element 33 maintains the correct position and shape during installation and use. The guide post 18 is a protruding part at the bottom of the housing 1, and its shape and size match one end of the elastic element 33. The material of the guide post 18 can be metal or plastic, or other materials with a certain strength and rigidity. The mounting groove 323 is an upwardly extending part at the lower end of the adjusting block 32, and its shape and size match the other end of the elastic element 33. The main function of the mounting groove 323 is to insert the elastic element 33, so that the adjusting block 32 can be stably connected to the elastic element 33 and maintain a certain elasticity during movement. The material of the mounting groove 323 can be the same as that of the adjusting block 32, or other materials with sufficient strength and rigidity. One end of the elastic element 33 is sleeved on the outer periphery of the guide post 18, and the other end is inserted into the mounting groove 323 of the adjusting block 32. This installation method allows the elastic element 33 to stably provide elasticity and reset function under the constraint of the guide post 18 and the mounting groove 323. The elastic element 33 can be made of spring, rubber, or other materials with elastic recovery capability. By combining the guide post 18, the mounting groove 323, and the elastic element 33, a stable and reliable connection structure is formed, which not only provides stable support and guidance but also realizes the self-locking and unlocking functions of the socket. At the same time, since the guide post 18 and the mounting groove 323 are relatively simple and easy to manufacture, the cost of the entire socket structure is effectively controlled.

[0050] In this optional embodiment, when the adjusting block 32 is subjected to an external force (such as pressing the button 322), it moves along the direction of the guide post 18. At this time, the elastic element 33 is compressed and stores energy. When the external force disappears, the elastic element 33 releases the energy, pushing the adjusting block 32 back to its original position, making the unlocking and self-locking process of the socket more stable and reliable. Through the constraint of the guide post 18 and the mounting groove 323, this embodiment ensures that the elastic element 33 maintains the correct position and shape during installation and use, thereby improving the stability of the entire socket structure. The guide post 18 and the mounting groove 323 reduce friction and wear of the elastic element 33 during movement, extending its service life. The guide post 18 and the mounting groove 323 make the installation process of the elastic element 33 simpler and more intuitive, reducing installation difficulty and cost.

[0051] Optionally, such as Figure 6 As shown, a slot 111 is provided on the inner side wall of the grounding socket 11. The slot 111 is located at the upper end of the grounding sleeve 14, and the first end 312 is inserted into the slot 111.

[0052] Specifically, a slot 111 is provided on the inner wall of the grounding socket 11. The slot 111 is a specific groove structure used to cooperate with the first end 312 of the card 31, ensuring that the first end 312 of the card 31 can be stably inserted and fixed in the appropriate position. The first end 312 of the card 31 can be inserted into the slot 111. The insertion method allows the card 31 to be firmly fixed in the grounding socket 11, while allowing it to rotate around the first end 312 at a certain angle.

[0053] In this optional embodiment, the card slot 111 has a space for the first end 312 to rotate. The first end 312 of the card 31 is inserted into the card slot 111, which is simple to assemble and occupies little space. When the grounding pin of the three-prong plug is inserted into the socket, the grounding pin will first contact the inclined part of the card 31. As the grounding pin is further inserted, the pin will push the card 31 to rotate around its first end 312 (i.e., the part inserted into the card slot 111), compressing the elastic member 33. After insertion, the elastic member 33 restores its deformation, pushing the second end 313 of the card 31 to rotate around the first end 312, so that the card 31 is tilted again relative to the central axis of the grounding socket 11, so that the insertion through hole 311 of the card 31 engages with the grounding pin, thereby ensuring that the plug can be firmly fixed in the socket. When it is necessary to unplug the plug, the user only needs to press the adjustment block 32 (as described above, button 322) to reduce the tilt angle of the card 31, and the plug can be easily unplugged.

[0054] Optionally, such as Figure 7 As shown, the grounding socket 14 includes a base plate 141. Both ends of the base plate 141 are connected to clamping springs 142. A clamping gap 143 is formed between the two clamping springs 142 for the insertion of the grounding pin. The lower end of the base plate 141 extends out of the grounding socket 11 and is provided with a wiring hole 144. The grounding input copper strip 5 is inserted into the wiring hole 144.

[0055] Specifically, the grounding socket 14 is a component specifically designed to receive and secure the grounding pin. It consists of a base plate 141 as its main body, with two clamping springs 142 connected to each end of the base plate 141. The clamping springs 142 have a certain degree of elasticity, forming a clamping gap 143 between the two springs for inserting the grounding pin. The size and shape of the gap match the grounding pin to ensure stable insertion and secure clamping. The lower end of the base plate 141 extends beyond the grounding socket 11 and has a wiring hole 144. The wiring hole 144 is used to connect the grounding input copper strip 5, and its size and shape match the grounding input copper strip 5 to ensure smooth insertion into the wiring hole 144 and good electrical contact with the base plate 141. The grounding input copper bar 5 is a conductive component used to connect the grounding socket 14 to the grounding system of the electrical equipment. By being inserted into the wiring hole 144, the grounding input copper bar 5 can introduce the current on the grounding pin into the grounding system of the electrical equipment, thereby ensuring the safe operation of the electrical equipment.

[0056] In this optional embodiment, the grounding socket 14 can firmly hold the grounding pin by means of the clamping spring 142 and the clamping gap 143, preventing it from loosening or falling off, and ensuring the safety and reliability of electrical equipment in terms of grounding protection. The clamping spring 142 has a certain degree of elasticity and can adapt to grounding pins of different sizes, thereby improving the compatibility and stability of the grounding socket 14. Through the wiring hole 144 and the grounding input copper strip 5, the installation process of the grounding socket 14 becomes simpler and more convenient. The user only needs to insert the grounding input copper strip 5 into the wiring hole 144, without the need for complicated soldering or connection operations. In this embodiment, the structure of the neutral socket 15 and the live socket 16 is the same as the structure of the grounding socket 14 described above.

[0057] Optionally, such as Figure 7 , Figure 8 As shown, a limiting block 112 is provided on the inner wall of the grounding socket 11. The end of the clamping spring piece 142 away from the card 31 abuts against the upper end of the limiting block 112. A limiting groove 113 is provided on the inner wall of the grounding socket 11. The limiting groove 113 is located at the lower end of the limiting block 112. Outwardly extending snap-fit ​​blocks 145 are provided on both sides of the substrate 141. The snap-fit ​​blocks 145 are connected to the limiting groove 113.

[0058] Specifically, a limiting block 112 is provided on the inner wall of the grounding socket 11, which serves as a guide and positioning element. The limiting block 112 is a block-shaped structure protruding from the inner wall of the grounding socket 11, and its shape and size match the free end of the clamping spring 142. When the clamping spring 142 is inserted into the grounding socket 11, its free end naturally abuts against the upper end of the limiting block 112, aligning the clamping gap 143 of the grounding sleeve 14 with the insertion direction of the grounding pin, thus restricting the downward sliding of the grounding sleeve 14 relative to the grounding socket 11, achieving initial positioning and fixation. In addition to the limiting block 112, the inner wall of the grounding socket 11 is also provided with a limiting groove 113. The limiting groove 113 is located at the lower end of the limiting block 112. The lower end of the substrate 141 is provided with outwardly extending locking blocks 145 on both sides. When the substrate 141 is inserted into the grounding socket 11, the two locking blocks 145 will slide along the lower end of the limiting groove 113 until they abut against the lower end of the limiting groove 113, restricting the grounding sleeve 14 from sliding upward relative to the grounding socket 11. At this time, the locking blocks 145 are firmly locked by the limiting groove 113, thereby preventing the substrate 141 (and the entire grounding sleeve 14) from moving up and down in the grounding socket 11.

[0059] In this optional embodiment, the grounding sleeve 14 is firmly fixed in the grounding socket 11 through the cooperation of the limiting block 112, the limiting groove 113, and the snap-fit ​​block 145, avoiding loosening or falling off due to improper installation or external force, thus improving the overall stability and safety of the socket. Furthermore, the user only needs to insert the grounding sleeve 14 into the grounding socket 11, ensuring that the free end of the clamping spring 142 abuts against the upper end of the limiting block 112 and that the snap-fit ​​block 145 is correctly engaged in the limiting groove 113. No additional tools or complex operating steps are required, making the fixing method simple and convenient. Moreover, because the limiting block 112 and the snap-fit ​​block 145 have a certain degree of tolerance, this fixing method can be applied to grounding sleeves 14 of different sizes and shapes, enabling the socket to be compatible with more types of grounding sleeves 14, improving the practicality and flexibility of the socket. In this embodiment, the connection and fixing method between the live wire socket 12 and the live wire sleeve 16, and the connection and fixing method between the neutral wire socket 13 and the neutral wire sleeve 15 are the same as the connection and fixing method between the ground wire socket 11 and the ground wire sleeve 14.

[0060] Optionally, such as Figure 8 As shown, the outer peripheral sidewall of the housing 1 is provided with several buckles 19 at intervals, which are used to connect with the housing of the power distribution unit.

[0061] Specifically, the latch 19 is typically a structure with a certain degree of elasticity, capable of deforming under external force and returning to its original shape after the force is removed. The shape and size of the latch 19 usually match the corresponding structure on the housing of the power distribution unit to ensure a tight and stable connection. During assembly, the housing 1 mates with the corresponding structure on the housing of the power distribution unit via the latch 19. As the mating deepens, the latch 19 deforms under the pressure of the housing of the power distribution unit until it is fully engaged in the corresponding position on the housing of the power distribution unit. Once the latch 19 is fully engaged, it returns to its original shape and is firmly fixed to the housing of the power distribution unit, thus achieving a secure connection between the socket functional module and the housing of the power distribution unit.

[0062] In this optional embodiment, the connection between the snap-fit ​​19 and the power distribution unit housing greatly simplifies the assembly process between the housing 1 and the power distribution unit. Users can complete the assembly without using additional tools or fasteners, improving assembly efficiency and convenience.

[0063] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
