Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a multifunctional socket that can achieve zero-ground conversion. Background Technology

[0002] A three-phase socket is a type of socket used to connect three-phase power supplies, primarily providing convenient power for most AC electrical equipment in industrial applications. A three-phase socket panel typically has four holes for connecting three live wires and one neutral or ground wire.

[0003] In the use of three-phase sockets, because 380V four-hole sockets are configured with either three live wires and one neutral wire or three live wires and one ground wire, a three live wire and one neutral wire socket cannot be used when it needs to provide power to a three live wire device. Currently, manual adjustment of the neutral and ground wires of the three-phase sockets on site is usually required, which is not only time-consuming and labor-intensive, but also greatly reduces the lifespan of the power supply equipment. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-functional socket that can realize zero-ground conversion, aiming to solve the problem that manually adjusting the zero-ground of three-phase sockets on site is not only time-consuming and laborious, but also greatly reduces the lifespan of power supply equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional socket capable of switching between neutral and ground wires, comprising a socket body, a cover plate on the upper side of the socket body, a neutral wire terminal, a changeover switch, and multiple live wire terminals on the inner bottom wall of the socket body, the output end of the neutral wire terminal being electrically connected to the input end of the changeover switch, the two output ends of the changeover switch being connected to the neutral wire and the ground wire respectively, the upper outer wall of the changeover switch passing through the upper side of the cover plate, a locking mechanism being provided on the lower side of the cover plate, one side of the locking mechanism being abutted against one side of the changeover switch, and a display component being provided on the upper side of the neutral wire terminal.

[0006] The above technical solution connects the output terminals on both sides of the changeover switch to the neutral and ground wires respectively. When a neutral-to-ground switch needs to be switched, the switching can be completed by simply moving the switch lever. This solves the problem that manually adjusting the neutral and ground wires of the three-phase sockets on site is not only time-consuming and laborious, but also greatly reduces the lifespan of the power supply equipment.

[0007] Preferably, the locking mechanism includes a slide rod, the lower end of which is fixedly connected to a magnetic slider. The magnetic slider is slidably connected inside the cover plate, the outer wall of which passes through the lower side of the cover plate, and a magnet is provided on the upper side of the cover plate. The outer wall of the slide rod passes through the upper and lower sides of the magnet. A locking assembly is provided on the lower side of the cover plate, one side of which is in contact with one side of the selector switch, and the side of which is away from the selector switch is in contact with one side of the magnetic slider. One side of the magnetic slider has an arc-shaped design.

[0008] Preferably, the locking assembly includes a locking pin, the outer wall of which is provided with a ring plate, a spring is fixedly connected to one side of the ring plate, and a fixing plate is provided on the opposite side of the spring and the ring plate. The upper side of the fixing plate is fixedly connected to the lower side of the cover plate, the outer wall of the locking pin passes through the fixing plate, one side of the locking pin is in contact with one side of the changeover switch, and the side of the locking pin away from the changeover switch is in contact with one side of the magnetic slider.

[0009] Preferably, a rectangular groove is provided on the lower side of the cover plate, and the outer walls of the magnetic slider are slidably connected to the inner wall of the rectangular groove, with the outer walls of the magnetic slider passing through the lower side of the rectangular groove.

[0010] Preferably, a through hole is provided on the lower side of the socket body, and the outer wall of the ground wire passes through the through hole.

[0011] Preferably, the display component includes an indicator light and a label. The label is disposed on the upper side of the cover plate. There is a pre-set gap between the label and one side of the upper side of the selector switch. A power module is disposed on the inner bottom wall of the socket body. The power module is electrically connected to the live wire terminal, the neutral wire terminal, and the indicator light.

[0012] Preferably, the display component includes a display screen, the display screen is electrically connected to a microcontroller, the power module is electrically connected to both the display screen and the microcontroller, and the microcontroller is connected to both the neutral wire and the ground wire.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the socket body provides support for the cover plate. When it is necessary to switch between neutral and ground wires, the switching work can be completed by toggling the changeover switch and cooperating with the neutral wire, live wire, and neutral wire terminals. At the same time, the switch lever of the changeover switch is locked by the locking mechanism to improve safety. The neutral and ground status is displayed by the display component, thus solving the problem that manually adjusting the neutral and ground of the three-phase socket on site is not only time-consuming and laborious, but also greatly reduces the lifespan of the power supply equipment.

[0014] 2. In this utility model, by inserting the device plug into the cover plate, the plug presses against the slide rod, causing the slide rod to push the magnetic slider downwards and press against the locking pin. This causes the outer wall of the locking pin at the end away from the magnetic slider to slide and fit against the outer wall of the switch lever of the changeover switch. Through the cooperation of the ring plate and the spring, the locking mechanism locks the changeover switch.

[0015] 3. In this utility model, the display components are designed as indicator lights and signs, and the display of the neutral and ground states is achieved through the cooperation of the power module, neutral wire terminal and live wire terminal.

[0016] 4. In this utility model, the display component is designed to be a microcontroller and a display screen. The power supply module supplies power to the microcontroller and the display screen. By connecting the microcontroller to the neutral and ground wires, the microcontroller displays the zero-ground state through the display component, thereby realizing the display of the zero-ground transition state.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example 1: Reference Figure 1 and Figure 2 The present invention provides an embodiment of a multi-functional socket capable of switching between neutral and ground wires, comprising a socket body 7, a cover plate 1 on the upper side of the socket body 7, a neutral wire terminal 3, a changeover switch 8 and multiple live wire terminals 6 on the inner bottom wall of the socket body 7, the output end of the neutral wire terminal 3 being electrically connected to the input end of the changeover switch 8, the two output ends of the changeover switch 8 being connected to a neutral wire 9 and a ground wire 10 respectively, the upper outer wall of the changeover switch 8 passing through the upper side of the cover plate 1, a locking mechanism 2 being provided on the lower side of the cover plate 1, one side of the locking mechanism 2 being fitted with one side of the changeover switch 8, and a display component 4 being provided on the upper side of the neutral wire terminal 3.

[0021] Specifically, the changeover switch 8 can be a double-pole double-throw switch or an electric changeover switch with a switch lever, which is existing technology. The socket body 7 provides support for the cover plate 1. This socket is a three-phase socket with four wires. There are three live wire terminals 6, with three live wires connected to the three live wire terminals 6 respectively. One neutral wire 9 is connected to one output terminal of the changeover switch 8, and the other output terminal of the changeover switch 8 is connected to the ground wire 10, which is grounded. The input terminal of the changeover switch 8 is connected to the output terminal of the neutral wire terminal 3. In use, the changeover switch 8 is in the neutral wire 9 connected state by default. When it is necessary to switch to the ground wire 10 connected state, the switch of the changeover switch 8 can be switched by toggling the switch. The switch lever of the changeover switch 8 is locked by the locking mechanism 2, and the current neutral and ground status is displayed by the display component 4. This solves the problem that manual adjustment of the neutral and ground of the three-phase socket on site is not only time-consuming and laborious, but also greatly reduces the lifespan of the power supply equipment.

[0022] Reference Figure 1 and Figure 5The locking mechanism 2 includes a slide rod 21, with a magnetic slider 22 fixedly connected to the lower end of the slide rod 21. The magnetic slider 22 is slidably connected inside the cover plate 1. The outer wall of the magnetic slider 22 passes through the lower side of the cover plate 1. A magnet 20 is provided on the upper side of the cover plate 1. The outer wall of the slide rod 21 passes through the upper and lower sides of the magnet 20. A locking component 23 is provided on the lower side of the cover plate 1. One side of the locking component 23 is in contact with one side of the changeover switch 8. The side of the locking component 23 away from the changeover switch 8 is in contact with one side of the magnetic slider 22. One side of the magnetic slider 22 has an arc-shaped design.

[0023] Specifically, the magnetic slider 22 is made of a magnetic material, such as iron, that attracts the magnet 20. After the device is in a neutral state, the switch lever of the selector switch 8 is turned to select the state, and the device plug is inserted into the socket body 7. One side of the device is in contact with the upper side of the cover plate 1, and at the same time, the one side of the device presses against the slide rod 21, causing the slide rod 21 to push the magnetic slider 22 downward, pressing against the locking component 23. This causes the locking component 23 to move closer to the selector switch 8 and fit against the outer wall of the switch lever, locking the current state of the selector switch 8, thus realizing the locking function of the locking mechanism 2. When the device plug is pulled out, on the one hand, the locking component 23 presses against the magnetic slider 22, and on the other hand, the attraction of the magnet 20 to the magnetic slider 22 causes the magnetic slider 22 to move upward, pushing the slide rod 21 back to its initial position, thus realizing the locking and unlocking function of the locking mechanism 2.

[0024] Reference Figure 1 and Figure 5 The locking assembly 23 includes a locking pin 233. The outer wall of the locking pin 233 is provided with a ring plate 230. A spring 231 is fixedly connected to one side of the ring plate 230. A fixing plate 232 is provided on the opposite side of the spring 231 and the ring plate 230. The upper side of the fixing plate 232 is fixedly connected to the lower side of the cover plate 1. The outer wall of the locking pin 233 passes through the fixing plate 232. One side of the locking pin 233 is in contact with one side of the changeover switch 8. The side of the locking pin 233 away from the changeover switch 8 is in contact with one side of the magnetic slider 22.

[0025] Specifically, the cover plate 1 provides support for the locking assembly 23. The magnetic slider 22 presses the locking pin 233 towards the changeover switch 8 and it comes into contact with the outer wall of the switch lever of the changeover switch 8, locking its state. During this period, the locking pin 233 drives the ring plate 230 to move in the same direction, compressing the spring 231. When the device is pulled out, the spring 231 rebounds, pushing the ring plate 230 towards the magnetic slider 22, which in turn moves the locking pin 233 and presses the magnetic slider 22. With the cooperation of the magnet 20, the slide bar 21 returns to its initial position, thus realizing the function of locking the changeover switch 8.

[0026] Reference Figure 5A rectangular groove 16 is provided on the lower side of the cover plate 1. The outer walls of the magnetic slider 22 are slidably connected to the inner wall of the rectangular groove 16, and the outer wall of the magnetic slider 22 passes through the lower side of the rectangular groove 16.

[0027] Specifically, the rectangular groove 16 provides space for the magnetic slider 22 to slide up and down. When the locking pin 233 is in the locked state of the changeover switch 8, the end of the locking pin 233 away from the changeover switch 8 exerts an upward pressure on the arc-shaped side of the magnetic slider 22, so that the magnetic slider 22 will not slide out of the rectangular groove 16, thereby helping to realize the locking function of the locking mechanism 2.

[0028] Reference Figure 2 A through hole 11 is provided on the lower side of the socket body 7, and the outer wall of the ground wire 10 passes through the through hole 11.

[0029] Specifically, by opening the through hole 11, the ground wire 10 can be grounded, which helps to realize the neutral-to-ground switching function of the socket.

[0030] Reference Figure 1 and Figure 2 The display component 4 includes an indicator light 14 and a label 15. The label 15 is located on the upper side of the cover plate 1. There is a pre-set gap between the label 15 and the upper side of the selector switch 8. The inner bottom wall of the socket body 7 is provided with a power module 12. The power module 12 is electrically connected to the live wire terminal 6, the neutral wire terminal 3, and the indicator light 14.

[0031] Specifically, indicator 15 includes a neutral wire indicator and a ground wire indicator, located on the upper and lower sides of the switch lever of the changeover switch 8, corresponding to the neutral and ground states of the changeover switch 8. The power module 12 is used for voltage conversion and is a three-phase power module, used to provide power to the indicator light 14, which can use an LED light. One end of the power module 12 is connected to the live wire terminal 6, and the other end is connected to the neutral wire terminal 3. When the socket is in the neutral wire 9 connected state, a circuit is formed, powering the indicator light 14, causing the indicator light 14 to light up. At this time, the switch lever of the changeover switch 8 is at the neutral wire indicator. If the indicator light 14 does not light up, it indicates a socket malfunction. When the changeover switch 8 is switched to the ground wire 10 connected state, the switch lever of the changeover switch 8 is at the ground wire indicator, and the indicator light 14 should not light up. If the indicator light 14 lights up, it indicates a malfunction, thus realizing the function of displaying the neutral and ground states of the display component 4.

[0032] Example 2: Reference Figure 3 and Figure 4 In this utility model, an embodiment is also provided, wherein the display component 4 includes a display screen 5, the display screen 5 is electrically connected to a microcontroller 13, the power module 12 is electrically connected to both the display screen 5 and the microcontroller 13, and the microcontroller 13 is connected to both the neutral wire 9 and the ground wire 10.

[0033] Specifically, in this embodiment, one end of the power module 12 is connected to the neutral line 9, and its circuit is always present. The power module 12 provides power to the microcontroller 13 and the display screen 5. The neutral line 9 and the ground line 10 are respectively connected to the signal terminals of the microcontroller 13. The microcontroller 13 monitors the neutral and ground status in real time and displays it on the display screen 5, thereby realizing the function of displaying the neutral and ground status of the display component 4.

[0034] Working principle: When using this socket, the device's neutral and ground power conditions are determined. The neutral and ground status of the socket is determined by the display component 4, and the neutral and ground status can be switched by the changeover switch 8. If the display component 4 consists of an indicator light 14 and a mark 15, when the indicator light 14 is lit and the switch lever of the changeover switch 8 points to the neutral wire mark, the neutral wire 9 is connected. When the indicator light 14 is not lit and the switch lever of the changeover switch 8 points to the ground wire mark, the ground wire 10 is connected. If the display component 4 consists of a display screen 5 and a microcontroller 13, the neutral and ground status of the socket can be viewed through the display screen 5.

[0035] Next, the device plug is inserted into the socket body 7. The device presses against the slide bar 21, causing the slide bar 21 to push the magnetic slider 22 downward, so that the locking pin 233 moves closer to the changeover switch 8 and fits against the outer wall of the switch lever of the changeover switch 8, locking its state. This solves the problem that manually adjusting the zero ground of the three-phase socket on site is not only time-consuming and laborious, but also greatly reduces the lifespan of the power supply equipment.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
