Description

FIELD OF TECHNOLOGY

[0002] With the development of the LED industry, traditional lighting lamps have been gradually replaced by LED lamps, and the LED lamps all need to be equipped with an LED drive power supply. The LED power supply has the advantages of constant voltage or constant current output, high power factor, high conversion efficiency, long service life, dimmable light, and the like, ensuring high energy efficiency and stability of the LED lamp. Therefore, the LED drive power supply has been widely used in increasing lighting lamps.

[0003] Nowadays, the three-phase power is used mostly to provide power for LED drive power supply. Specifically, any one phase line is selected from the three-phase power to be connected to the LED drive power supply. In some scenes of an electrical device requiring arrangement of a large amount of LED lamps, maintaining relative balance between the loading powers on three phase lines needs to be considered. In one method, the connection layout of each phase line needs to be designed before the electrical device is mounted. However, this method requires long mounting time and has poor flexibility. If a new electrical device needs to be added subsequently, the power grid is likely to be unstable. In another method, when a line is arranged, a connector and a phase shifter are both mounted on the same line. In this way, the phase shifter can achieve power phase shifting, but the line structure is complex, requiring a large amount of time for mounting, resulting in low efficiency.

The connection device includes a phase selector device, disposed in a phase selector house, having an outgoing conductor, a contact, removable between different phase connections, and a phase selector indicator which can be observed from outside.SUMMARY

[0022] For further understanding of the content, features, and benefits of this application, the following embodiments are used as examples for detailed description with reference to the accompanying drawings:Embodiment 1:

[0023] Referring to FIGs. 1 to 3, FIG. 1 is a schematic structural diagram of a plug connector for arbitrary phase shifting according to an embodiment; FIG. 2 is a schematic structural diagram of a plug connector for arbitrary phase shifting after phase shifting according to an embodiment; and FIG. 3 is another schematic structural diagram of a plug connector for arbitrary phase shifting after phase shifting according to an embodiment. The plug connector for arbitrary phase shifting in this embodiment includes a connecting assembly 1, a phase shifting assembly 2, and a terminal assembly 3. The connecting assembly 1 is electrically connected to the electrical device. The terminal assembly 3 includes a plurality of phase-line terminal members 31, and the phase-line terminal member 31 is electrically connected to the phase line. The phase shifting assembly 2 is movably bridged between the connecting assembly 1 and the plurality of phase-line terminal members 31. The phase shifting assembly 2 is moved to enable two ends of the phase shifting assembly 2 to be electrically connected to or disconnected from the connecting assembly 1 and one of the phase-line terminal members 31, respectively.

[0024] Still referring to FIGs. 1 to 3, FIGs. 1 to 3 are schematic diagrams of three different phase lines being switched according to this embodiment. The plug connector for arbitrary phase shifting in this embodiment is mounted on a line to connect an electrical device and an external power supply. Along a movement direction of the phase shifting assembly 2, the plurality of phase-line terminal members 31 are sequentially spaced apart. The phase shifting assembly 2 is moved to enable an end of the phase shifting assembly 2 to be electrically connected to or disconnected from one of the phase-line terminal members 31. Three phase-line terminal members 31 are provided in this embodiment and applied to a three-phase power supply. Each of the phase-line terminal members 31 is connected to one phase line in the three-phase power supply. During movement of the phase shifting assembly 2, one end of the phase shifting assembly 2 moves back and forth between the phase-line terminal members 31. When one end of the phase shifting assembly 2 is in contact with one of the phase-line terminal members 31, the phase shifting assembly 2 electrically connects the phase line of the phase-line terminal member 31 and the connecting assembly 1. That is, the phase line on the phase-line terminal member 31 supplies power to the electrical device on the connecting assembly 1. When the phase shifting assembly 2 moves until one end is located between a gap between adjacent two of the phase-line terminal members 31, the phase shifting assembly 2 is disconnected from the phase-line terminal member 31 to be in a neutral state.

[0025] After the plug connector for arbitrary phase shifting is mounted on a line, the phase shifting assembly 2 is arranged and moved to enable one end thereof to be electrically connected to one of the phase-line terminal members 31, achieving that one of three phase lines is selected for connection. In this way, the power phase shifting can be achieved. Any phase line can be selected based on the actual situation to provide electric energy. In addition, the connecting assembly 1 is electrically connected to an electrical device such as lamp. It can be understood that the use of the plug connector for arbitrary phase shifting in this embodiment is equivalent to integrating the power phase shifting function on a connector without the need to mount both the connector and a phase shifter on the same line. This simplifies the line structure, reduces the line connection difficulty, and improves the mounting efficiency. During use, the connecting assembly 1 only needs to be connected to the electrical device, and the phase-line terminal member 31 is connected to the phase line. The phase shifting assembly 2 is moved to be connected to one of the phase lines selected, so as to provide electric energy to the electrical device, thus achieving power phase shifting. This embodiment features a simple structure, low manufacturing costs, and a fast mounting speed, is suitable for a three-phase line in any manner, and has wide application scenes.

[0026] Referring to FIG. 4, FIG. 4 is a schematic structural diagram of a terminal assembly according to an embodiment. Preferably, the terminal assembly 3 further includes at least one non-phase line terminal member 32, the non-phase line terminal member 32 is apart from the phase-line terminal member 31, and the non-phase line terminal member 32 is configured to be connected to a non-phase line or in a vacant status. During specific application, four non-phase line terminal members 32 are provided in this embodiment. The four non-phase line terminal members 32 are sequentially and alternately spaced apart from the three phase-line terminal members 31. The non-phase line terminal member 32 is configured to be connected to a non-phase line such as a neutral line, a ground line, and a functional line or in a vacant status which indicates no connection to any line. It can be understood that when the phase shifting assembly 2 is moved to be directly opposite one phase-line terminal member 31, it is electrically connected to the phase-line terminal member 31. That is, a phase line is selected to be connected to the phase-line terminal member 31, so as to provide electric energy. When the phase shifting assembly 2 is moved to be directly opposite one non-phase line terminal member 32, the phase shifting assembly 2 is not connected to the non-phase line terminal member 32, and both the phase shifting assembly 2 and the phase-line terminal member 31 are in off status. That is, in this case, the phase shifting assembly 2 is in a vacant status, and the entire circuit is in a power-off status. Certainly, in other embodiments, one or more non-phase line terminal members 32 may be provided. Non-phase line terminal members 32 of a corresponding quantity may be arranged based on the actual use requirements to be connected to a neutral line, a ground line, and another functional line or not connected to any line.

[0027] Referring to FIG. 5, FIG. 5 is a schematic structural diagram of a phase-shifting guide member according to an embodiment. Preferably, the connecting assembly 1 includes a connecting member 11 and a phase-shifting guide member 12. The connecting member 11 is disposed at the phase-shifting guide member 12, the connecting member 11 has one end electrically connected to the electrical device and the other end in on-off coordination with the phase shifting assembly 2, the phase-shifting guide member 12 is provided with a guide slot 121, the phase shifting assembly 2 is movably disposed in the guide slot 121, and the guide slot 121 limits and guides movement of the phase shifting assembly 2. When the phase shifting assembly 2 is moved for phase shifting, with the guide slot 121 arranged, the phase shifting assembly 2 can move along the slot direction of the guide slot 121 all the time, ensuring the accuracy of movement of the phase shifting assembly 2, thus ensuring that during movement. The phase shifting assembly 2 can be controlled accurately to make a switch for phase shifting. Specifically, the connecting member 11 is a standard member made of a conductive material such as copper, and the phase-shifting guide member 12 is made of an insulating material. The guide slot 121 in this embodiment is in a linear shape. That is, the phase shifting assembly 2 moves back and forth linearly. In addition, the plurality of phase-line terminal members 31 are sequentially spaced apart along the slot direction of the guide slot 121. With the movement of the phase shifting assembly 2, one end of the phase shifting assembly 2 moves back and forth between a plurality of phase-line terminal members 31, so as to be connected to or disconnected from one phase-line terminal member 31. In other embodiments, the guide slot 121 may alternatively be arc-shaped or in an irregular shape, which is not limited herein.

[0028] Referring to FIGs. 1 to 5, preferably, an end of the phase-shifting guide member 12 is provided with a plurality of grooves 123 spaced apart from each other, the phase-line terminal member 31 includes a terminal body 311 and a connecting terminal 312 connected to the terminal body 311, the plurality of terminal bodies 311 are spaced apart on a side of the phase-shifting guide member 12 and each electrically connected to one phase line, and the plurality of connecting terminals 312 respectively correspond to the plurality of grooves 123. The phase shifting assembly 2 moves along a slot direction of the guide slot 121, when one end of the phase shifting assembly 2 is directly opposite one of the grooves 123, this end of the phase shifting assembly 2 is electrically connected to the connecting terminal 312 in the groove 123, and when one end of the phase shifting assembly 2 is staggered with the groove 123, this end of the phase shifting assembly 2 is disconnected from the connecting terminal 312. During specific application, the terminal body 311 is located at the bottom of the phase-shifting guide member 12, and the connecting terminal 312 is disposed on the top of the terminal body 311 and located in the groove 123. When one end of the phase shifting assembly 2 moves into the groove 123, this end of the phase shifting assembly 2 is in contact with the connecting terminal 312 in the groove 123, so as to be electrically connected to one phase line. When one end of the phase shifting assembly 2 moves to a space between two adjacent grooves 123, one end of the phase shifting assembly 2 is staggered with the connecting terminal 312. In this case, it is in a vacant, that is, power-off status. Specifically, the terminal body 311 and the connecting terminal 312 are of an integrated structure, which can be made by a conductive material, such as copper. The non-phase line terminal member 32 and the phase-line terminal member 31 are similar in structure and both made of a conductive material such as copper. However, the non-phase line terminal members 32 all have a terminal body and no connecting terminal. In this way, all the non-phase line terminal member 32 are located at the bottom of the phase-shifting guide member 12.

[0029] Referring to FIGs. 1 to 5, preferably, along a slot direction of the guide slot 121, a plurality of protrusions 1211 are spaced apart in the guide slot 121, and the plurality of phase-line terminal members 31 are each directly opposite a gap between adjacent two of the protrusions 1211. The phase shifting assembly 2 moves along the slot direction of the guide slot 121, when the phase shifting assembly 2 is in contact with the protrusion 1211, the phase shifting assembly 2 is disconnected from the phase-line terminal member 31, and when the phase shifting assembly 2 is in the gap, the phase shifting assembly 2 is electrically connected to one of the phase-line terminal members 31. With the arrangement of the protrusion 1211, during movement of the phase shifting assembly 2, when the phase shifting assembly 2 moves to the protrusion 1211, the protrusion 1211 pushes up the phase shifting assembly 2, enabling two ends of the phase shifting assembly 2 to be separated from the phase-line terminal member 31 and the connecting assembly 1, respectively, so as to turn off the whole circuit. It should be particularly noted that, in this embodiment, the phase-line terminal member 31 is directly opposite a gap between two adjacent protrusions 1211, that is, a recess between two adjacent protrusions 1211. In other words, when the phase shifting assembly 2 is connected to one phase-line terminal member 31, the phase shifting assembly 2 is directly located in the recess between two protrusions 1211. The two adjacent protrusions 1211 fix the corresponding position of the phase shifting assembly 2, allowing it to be clamped between two protrusions 1211 without vibration during connection to the phase-line terminal member 31, ensuring connection stability. In brief, the recess present between the two adjacent protrusions 1211 can be regarded as a gear position. When the recess is directly opposite the phase-line terminal member 31, the recess can be regarded as a phase gear. When the phase shifting assembly 2 moves to the gear, the phase line on the phase-line terminal member 31 supplies power to the electrical device. When the recess is not directly opposite the phase-line terminal member 31, the recess can be regarded as a neutral gear. When the phase shifting assembly 2 moves to the gear position, the phase shifting assembly 2 is disconnected from the phase-line terminal member 31. In this case, the circuit is in an off status. The three phase-line terminal members 31 in this embodiment respectively correspond to the three phase gears, and the non-phase line terminal member 32 corresponds to the neutral gear. In this embodiment, the phase gears and the neutral gears are sequentially and alternately arranged. During application, the phase shifting assembly 2 can be moved to a corresponding gear position based on the use requirement, thus achieving switching for phase shifting of the three-phase power supply and neutral gear switching with simple use. Certainly, in other embodiments, the quantities of phase gears and neutral gears and their sequence can be adjusted correspondingly based on actual requirements.

[0030] Referring to FIG. 6, FIG. 6 is a schematic structural diagram of a phase shifting assembly according to an embodiment. The phase shifting assembly 2 includes a phase-shifting toggle member 21, an elastic conductive member 22, and a pressing cover member 23. The elastic conductive member 22 is connected to the phase-shifting toggle member 21 and movably disposed in the guide slot 121. The pressing cover member 23 is disposed at the phase-shifting guide member 12 and presses against the elastic conductive member 22 in the guide slot 121, the pressing cover member 23 is provided with a toggle slot 231 directly opposite the guide slot 121, and the phase-shifting toggle member 21 is movably disposed in the toggle slot 231. The phase-shifting toggle member 21 is toggled to move in the toggle slot 231, driving the elastic conductive member 22 to synchronously move in the guide slot 121. When the elastic conductive member 22 moves to be in contact with the protrusion 1211, the elastic conductive member 22 is disconnected from the phase-line terminal member 31, and when the elastic conductive member 22 moves into the gap, the elastic conductive member 22 is electrically connected to one of the phase-line terminal members 31. During specific application, the elastic conductive member 22 includes a spring 221 and a conductive sheet 222. Two ends of the spring 221 are connected to the phase-shifting toggle member 21 and the conductive sheet 222, respectively. The spring 221 may be replaced with another elastic part. When the phase-shifting toggle member 21 moves to the phase gear, under the elastic action of the spring 221, the conductive sheet 222 is tightly pressed at the connecting member 11 and the connecting terminal 312, to enhance the stability of connection between the conductive sheet 222 and the connecting terminal 312. The connecting member 11 is electrically connected to the connecting terminal 312 via the conductive sheet 222. That is, the electrical device can draw power from the phase line of the phase gear. When the phase-shifting toggle member 21 moves to be in contact with the protrusion 1211, the protrusion 1211 pushes the conductive sheet 222, enabling the spring 221 to be compressed for deformation. In this case, the conductive sheet 222 leaves the connecting member 11 and the connecting terminal 312: the conductive sheet 222 is disconnected from both the connecting member 11 and the connecting terminal 312. It should be particularly noted that, when the phase-shifting toggle member 21 moves to the neutral gear, one end of the conductive sheet 222 is located on a side of the connecting terminal 312, and under the elastic action of the spring 221, one end of the conductive sheet 222 is pressed between two adjacent grooves of the phase-shifting guide member 12. In this case, the conductive sheet 222 is not connected to any connecting terminal 312, that is, in a power-off neutral-gear status. In brief, a user toggles the phase-shifting toggle member 21 to move in the toggle slot 231, so as to reach a corresponding phase gear, such that a phase line at this gear position can be selected for power supply, and then to a neutral gear, such that disconnection can be achieved. This can achieve switching for phase shifting of the phase line and neutral gear switching.

[0031] Referring to FIG. 7, FIG. 7 is schematic structural diagram of a connecting member according to an embodiment. Preferably, the connecting member 11 includes a connecting portion 111 and a contact row 112. The connecting portion 111 is electrically connected to the contact row 112, the contact row 112 is disposed at the phase-shifting guide member 12, and the connecting portion 111 is electrically connected to the electrical device. The contact row 112 is disposed along a slot direction of the guide slot 121, and when the phase shifting assembly 2 moves in the guide slot 121, the other end of the phase shifting assembly 2 is in on-off coordination with the contact row 112. During specific application, the connecting portion 111 and the contact row 112 are both made of a conductive material. The contact row 112 is in the shape of a long strip and disposed on a side of the guide slot 121 along a slot direction of the guide slot 121. The plurality of connecting terminals 312 are spaced apart on the other side of the guide slot 121 along the slot direction of the guide slot 121. In other words, the phase-shifting toggle member 21 moves along the slot direction of the guide slot 121. One end of the conductive sheet 222 moves back and forth along the connection direction of the plurality of connecting terminals 312, to achieve phase shifting. The other end of the conductive sheet 222 moves back and forth along the length direction of the contact row 112 to be in on-off coordination with the contact row 112 through the pushing up by the protrusion 1211.

[0032] Referring to FIG. 7, preferably, two ends of the contact row 112 are each provided with a mounting block 1121, a mounting hole 122 is provided at a position of the phase-shifting guide member 12 corresponding to the mounting block 1121, and the mounting block 1121 is clamped in the mounting hole 122, enabling the contact row 112 to be clamped and mounted at the phase-shifting guide member 12. The arrangement of the mounting block 1121 and the mounting hole 122 allows stable mounting of the contact row 112 on the phase-shifting guide member 12, improving the mounting stability and ensuring no vibration during use. Specifically, the connecting portion 111 is in a clamp shape and configured to clamp the wire harness of the electrical device and achieve electrical connection with the contact row 112.

Optionally, the plug connector for arbitrary phase shifting further includes a housing assembly 4. The connecting assembly 1 is disposed in the housing assembly 4, and the wire harness of the electrical device extends into the housing assembly 4 to be electrically connected to the connecting assembly 1. The phase shifting assembly 2 is movably disposed at the housing assembly 4, one end of the phase-line terminal member 31 is in on-off coordination with the phase shifting assembly 2, and the other end extends outside the housing assembly 4 and is electrically connected to one phase line. During specific application, the housing assembly 4 is made of an insulating material. In this embodiment, the connecting assembly 1, the phase-line terminal member 31, the non-phase line terminal member 32, and the conductive sheet 222 are merely made of a conductive material, and the other components are made of an insulating material. The phase-line terminal member 31 and the non-phase line terminal member 32 are apart from each other in the housing assembly 4, and an insulating housing is disposed between the phase-line terminal member 31 and the non-phase line terminal member 32 for separation, ensuring no contact therebetween, thus improving the safety. Specifically, a plurality of gear indicators are disposed on the housing assembly 4 and respectively correspond to a plurality of phase gears and a plurality of neutral gears. For example, L1, L2, and L3 may be used as gear indicators for three phase gears, and neutral gear may be represented by N, representing a neutral position. It can be understood that when the phase shifting assembly 2 moves to be directly opposite the corresponding gear indicator, it is right at a corresponding gear. In this way, it is intuitive for the user to know about the gear switching situation, thus improving the product practicability.Embodiment 2:

[0034] A lamp in this embodiment includes the plug connector for arbitrary phase shifting in Embodiment 1, a lamp body, and a connecting wire harness. Two ends of the connecting wire harness are electrically connected to the connecting assembly 1 of the plug connector for arbitrary phase shifting and the lamp body, respectively. During specific application, lines of an external power source such as a phase line and a neutral line only need to be connected to the terminal assembly 3 for use, improving the mounting efficiency. Certainly, in other embodiments, the plug connector for arbitrary phase shifting may be alternatively integrated on another electrical device, to reduce the mounting difficulty and improve the mounting efficiency.

[0035] In summary, after the plug connector for arbitrary phase shifting is mounted on a line, the phase shifting assembly is arranged and moved to enable one end thereof to be electrically connected to one of the phase-line terminal members, achieving that one of three phase lines is selected for connection. In this way, the power phase shifting can be achieved. Any phase line can be selected based on the actual situation to provide electric energy. This is equivalent to integrating the power phase shifting function on a connector without the need to mount both the connector and a phase shifter on the same line. This simplifies the line structure, reduces the line connection difficulty, and improves the mounting efficiency. During use, the connecting assembly only needs to be connected to the electrical device, and the phase-line terminal member is connected to the phase line. The phase shifting assembly is moved to be connected to one of the phase lines selected, so as to provide electric energy to the electrical device, thus achieving power phase shifting. This embodiment features a simple structure, low manufacturing costs, and a fast mounting speed, is suitable for a three-phase line in any manner, and has wide application scenes.

FIELD OF TECHNOLOGY

[0001] The present invention relates to the field of power-supply phase-shifting technologies, and in particular to, a plug connector for arbitrary phase shifting and a lamp.BACKGROUND

[0002] With the development of the LED industry, traditional lighting lamps have been gradually replaced by LED lamps, and the LED lamps all need to be equipped with an LED drive power supply. The LED power supply has the advantages of constant voltage or constant current output, high power factor, high conversion efficiency, long service life, dimmable light, and the like, ensuring high energy efficiency and stability of the LED lamp. Therefore, the LED drive power supply has been widely used in increasing lighting lamps.

[0003] Nowadays, the three-phase power is used mostly to provide power for LED drive power supply. Specifically, any one phase line is selected from the three-phase power to be connected to the LED drive power supply. In some scenes of an electrical device requiring arrangement of a large amount of LED lamps, maintaining relative balance between the loading powers on three phase lines needs to be considered. In one method, the connection layout of each phase line needs to be designed before the electrical device is mounted. However, this method requires long mounting time and has poor flexibility. If a new electrical device needs to be added subsequently, the power grid is likely to be unstable. In another method, when a line is arranged, a connector and a phase shifter are both mounted on the same line. In this way, the phase shifter can achieve power phase shifting, but the line structure is complex, requiring a large amount of time for mounting, resulting in low efficiency.

The contact-and-locking bar has three phase conductor pins and a neutral conductor pin designed to cooperate with phase and neutral conductors disposed beside the longitudinal hole of the current rail. The contact-and-locking bar is pivoted and axially displaced by means of an operating arm provided with an eccentric. The operating arm is retained in a pulled down fastened position by means of a sliding lid, which cooperates with a built-in switch of the connection device. The connection device includes a phase selector device, disposed in a phase selector house, having an outgoing conductor, a contact, removable between different phase connections, and a phase selector indicator which can be observed from outside.SUMMARY

[0022] For further understanding of the content, features, and benefits of this application, the following embodiments are used as examples for detailed description with reference to the accompanying drawings:Embodiment 1:

[0023] Referring to FIGs. 1 to 3, FIG. 1 is a schematic structural diagram of a plug connector for arbitrary phase shifting according to an embodiment; FIG. 2 is a schematic structural diagram of a plug connector for arbitrary phase shifting after phase shifting according to an embodiment; and FIG. 3 is another schematic structural diagram of a plug connector for arbitrary phase shifting after phase shifting according to an embodiment. The plug connector for arbitrary phase shifting in this embodiment includes a connecting assembly 1, a phase shifting assembly 2, and a terminal assembly 3. The connecting assembly 1 is electrically connected to the electrical device. The terminal assembly 3 includes a plurality of phase-line terminal members 31, and the phase-line terminal member 31 is electrically connected to the phase line. The phase shifting assembly 2 is movably bridged between the connecting assembly 1 and the plurality of phase-line terminal members 31. The phase shifting assembly 2 is moved to enable two ends of the phase shifting assembly 2 to be electrically connected to or disconnected from the connecting assembly 1 and one of the phase-line terminal members 31, respectively.

[0024] Still referring to FIGs. 1 to 3, FIGs. 1 to 3 are schematic diagrams of three different phase lines being switched according to this embodiment. The plug connector for arbitrary phase shifting in this embodiment is mounted on a line to connect an electrical device and an external power supply. Along a movement direction of the phase shifting assembly 2, the plurality of phase-line terminal members 31 are sequentially spaced apart. The phase shifting assembly 2 is moved to enable an end of the phase shifting assembly 2 to be electrically connected to or disconnected from one of the phase-line terminal members 31. Three phase-line terminal members 31 are provided in this embodiment and applied to a three-phase power supply. Each of the phase-line terminal members 31 is connected to one phase line in the three-phase power supply. During movement of the phase shifting assembly 2, one end of the phase shifting assembly 2 moves back and forth between the phase-line terminal members 31. When one end of the phase shifting assembly 2 is in contact with one of the phase-line terminal members 31, the phase shifting assembly 2 electrically connects the phase line of the phase-line terminal member 31 and the connecting assembly 1. That is, the phase line on the phase-line terminal member 31 supplies power to the electrical device on the connecting assembly 1. When the phase shifting assembly 2 moves until one end is located between a gap between adjacent two of the phase-line terminal members 31, the phase shifting assembly 2 is disconnected from the phase-line terminal member 31 to be in a neutral state.

[0025] After the plug connector for arbitrary phase shifting is mounted on a line, the phase shifting assembly 2 is arranged and moved to enable one end thereof to be electrically connected to one of the phase-line terminal members 31, achieving that one of three phase lines is selected for connection. In this way, the power phase shifting can be achieved. Any phase line can be selected based on the actual situation to provide electric energy. In addition, the connecting assembly 1 is electrically connected to an electrical device such as lamp. It can be understood that the use of the plug connector for arbitrary phase shifting in this embodiment is equivalent to integrating the power phase shifting function on a connector without the need to mount both the connector and a phase shifter on the same line. This simplifies the line structure, reduces the line connection difficulty, and improves the mounting efficiency. During use, the connecting assembly 1 only needs to be connected to the electrical device, and the phase-line terminal member 31 is connected to the phase line. The phase shifting assembly 2 is moved to be connected to one of the phase lines selected, so as to provide electric energy to the electrical device, thus achieving power phase shifting. This embodiment features a simple structure, low manufacturing costs, and a fast mounting speed, is suitable for a three-phase line in any manner, and has wide application scenes.

[0026] Referring to FIG. 4, FIG. 4 is a schematic structural diagram of a terminal assembly according to an embodiment. Preferably, the terminal assembly 3 further includes at least one non-phase line terminal member 32, the non-phase line terminal member 32 is apart from the phase-line terminal member 31, and the non-phase line terminal member 32 is configured to be connected to a non-phase line or in a vacant status. During specific application, four non-phase line terminal members 32 are provided in this embodiment. The four non-phase line terminal members 32 are sequentially and alternately spaced apart from the three phase-line terminal members 31. The non-phase line terminal member 32 is configured to be connected to a non-phase line such as a neutral line, a ground line, and a functional line or in a vacant status which indicates no connection to any line. It can be understood that when the phase shifting assembly 2 is moved to be directly opposite one phase-line terminal member 31, it is electrically connected to the phase-line terminal member 31. That is, a phase line is selected to be connected to the phase-line terminal member 31, so as to provide electric energy. When the phase shifting assembly 2 is moved to be directly opposite one non-phase line terminal member 32, the phase shifting assembly 2 is not connected to the non-phase line terminal member 32, and both the phase shifting assembly 2 and the phase-line terminal member 31 are in off status. That is, in this case, the phase shifting assembly 2 is in a vacant status, and the entire circuit is in a power-off status. Certainly, in other embodiments, one or more non-phase line terminal members 32 may be provided. Non-phase line terminal members 32 of a corresponding quantity may be arranged based on the actual use requirements to be connected to a neutral line, a ground line, and another functional line or not connected to any line.

[0027] Referring to FIG. 5, FIG. 5 is a schematic structural diagram of a phase-shifting guide member according to an embodiment. Preferably, the connecting assembly 1 includes a connecting member 11 and a phase-shifting guide member 12. The connecting member 11 is disposed at the phase-shifting guide member 12, the connecting member 11 has one end electrically connected to the electrical device and the other end in on-off coordination with the phase shifting assembly 2, the phase-shifting guide member 12 is provided with a guide slot 121, the phase shifting assembly 2 is movably disposed in the guide slot 121, and the guide slot 121 limits and guides movement of the phase shifting assembly 2. When the phase shifting assembly 2 is moved for phase shifting, with the guide slot 121 arranged, the phase shifting assembly 2 can move along the slot direction of the guide slot 121 all the time, ensuring the accuracy of movement of the phase shifting assembly 2, thus ensuring that during movement. The phase shifting assembly 2 can be controlled accurately to make a switch for phase shifting. Specifically, the connecting member 11 is a standard member made of a conductive material such as copper, and the phase-shifting guide member 12 is made of an insulating material. The guide slot 121 in this embodiment is in a linear shape. That is, the phase shifting assembly 2 moves back and forth linearly. In addition, the plurality of phase-line terminal members 31 are sequentially spaced apart along the slot direction of the guide slot 121. With the movement of the phase shifting assembly 2, one end of the phase shifting assembly 2 moves back and forth between a plurality of phase-line terminal members 31, so as to be connected to or disconnected from one phase-line terminal member 31. In other embodiments, the guide slot 121 may alternatively be arc-shaped or in an irregular shape, which is not limited herein.

[0028] Referring to FIGs. 1 to 5, preferably, an end of the phase-shifting guide member 12 is provided with a plurality of grooves 123 spaced apart from each other, the phase-line terminal member 31 includes a terminal body 311 and a connecting terminal 312 connected to the terminal body 311, the plurality of terminal bodies 311 are spaced apart on a side of the phase-shifting guide member 12 and each electrically connected to one phase line, and the plurality of connecting terminals 312 respectively correspond to the plurality of grooves 123. The phase shifting assembly 2 moves along a slot direction of the guide slot 121, when one end of the phase shifting assembly 2 is directly opposite one of the grooves 123, this end of the phase shifting assembly 2 is electrically connected to the connecting terminal 312 in the groove 123, and when one end of the phase shifting assembly 2 is staggered with the groove 123, this end of the phase shifting assembly 2 is disconnected from the connecting terminal 312. During specific application, the terminal body 311 is located at the bottom of the phase-shifting guide member 12, and the connecting terminal 312 is disposed on the top of the terminal body 311 and located in the groove 123. When one end of the phase shifting assembly 2 moves into the groove 123, this end of the phase shifting assembly 2 is in contact with the connecting terminal 312 in the groove 123, so as to be electrically connected to one phase line. When one end of the phase shifting assembly 2 moves to a space between two adjacent grooves 123, one end of the phase shifting assembly 2 is staggered with the connecting terminal 312. In this case, it is in a vacant, that is, power-off status. Specifically, the terminal body 311 and the connecting terminal 312 are of an integrated structure, which can be made by a conductive material, such as copper. The non-phase line terminal member 32 and the phase-line terminal member 31 are similar in structure and both made of a conductive material such as copper. However, the non-phase line terminal members 32 all have a terminal body and no connecting terminal. In this way, all the non-phase line terminal member 32 are located at the bottom of the phase-shifting guide member 12.

[0029] Referring to FIGs. 1 to 5, preferably, along a slot direction of the guide slot 121, a plurality of protrusions 1211 are spaced apart in the guide slot 121, and the plurality of phase-line terminal members 31 are each directly opposite a gap between adjacent two of the protrusions 1211. The phase shifting assembly 2 moves along the slot direction of the guide slot 121, when the phase shifting assembly 2 is in contact with the protrusion 1211, the phase shifting assembly 2 is disconnected from the phase-line terminal member 31, and when the phase shifting assembly 2 is in the gap, the phase shifting assembly 2 is electrically connected to one of the phase-line terminal members 31. With the arrangement of the protrusion 1211, during movement of the phase shifting assembly 2, when the phase shifting assembly 2 moves to the protrusion 1211, the protrusion 1211 pushes up the phase shifting assembly 2, enabling two ends of the phase shifting assembly 2 to be separated from the phase-line terminal member 31 and the connecting assembly 1, respectively, so as to turn off the whole circuit. It should be particularly noted that, in this embodiment, the phase-line terminal member 31 is directly opposite a gap between two adjacent protrusions 1211, that is, a recess between two adjacent protrusions 1211. In other words, when the phase shifting assembly 2 is connected to one phase-line terminal member 31, the phase shifting assembly 2 is directly located in the recess between two protrusions 1211. The two adjacent protrusions 1211 fix the corresponding position of the phase shifting assembly 2, allowing it to be clamped between two protrusions 1211 without vibration during connection to the phase-line terminal member 31, ensuring connection stability. In brief, the recess present between the two adjacent protrusions 1211 can be regarded as a gear position. When the recess is directly opposite the phase-line terminal member 31, the recess can be regarded as a phase gear. When the phase shifting assembly 2 moves to the gear, the phase line on the phase-line terminal member 31 supplies power to the electrical device. When the recess is not directly opposite the phase-line terminal member 31, the recess can be regarded as a neutral gear. When the phase shifting assembly 2 moves to the gear position, the phase shifting assembly 2 is disconnected from the phase-line terminal member 31. In this case, the circuit is in an off status. The three phase-line terminal members 31 in this embodiment respectively correspond to the three phase gears, and the non-phase line terminal member 32 corresponds to the neutral gear. In this embodiment, the phase gears and the neutral gears are sequentially and alternately arranged. During application, the phase shifting assembly 2 can be moved to a corresponding gear position based on the use requirement, thus achieving switching for phase shifting of the three-phase power supply and neutral gear switching with simple use. Certainly, in other embodiments, the quantities of phase gears and neutral gears and their sequence can be adjusted correspondingly based on actual requirements.

[0030] Referring to FIG. 6, FIG. 6 is a schematic structural diagram of a phase shifting assembly according to an embodiment. The phase shifting assembly 2 includes a phase-shifting toggle member 21, an elastic conductive member 22, and a pressing cover member 23. The elastic conductive member 22 is connected to the phase-shifting toggle member 21 and movably disposed in the guide slot 121. The pressing cover member 23 is disposed at the phase-shifting guide member 12 and presses against the elastic conductive member 22 in the guide slot 121, the pressing cover member 23 is provided with a toggle slot 231 directly opposite the guide slot 121, and the phase-shifting toggle member 21 is movably disposed in the toggle slot 231. The phase-shifting toggle member 21 is toggled to move in the toggle slot 231, driving the elastic conductive member 22 to synchronously move in the guide slot 121. When the elastic conductive member 22 moves to be in contact with the protrusion 1211, the elastic conductive member 22 is disconnected from the phase-line terminal member 31, and when the elastic conductive member 22 moves into the gap, the elastic conductive member 22 is electrically connected to one of the phase-line terminal members 31. During specific application, the elastic conductive member 22 includes a spring 221 and a conductive sheet 222. Two ends of the spring 221 are connected to the phase-shifting toggle member 21 and the conductive sheet 222, respectively. The spring 221 may be replaced with another elastic part. When the phase-shifting toggle member 21 moves to the phase gear, under the elastic action of the spring 221, the conductive sheet 222 is tightly pressed at the connecting member 11 and the connecting terminal 312, to enhance the stability of connection between the conductive sheet 222 and the connecting terminal 312. The connecting member 11 is electrically connected to the connecting terminal 312 via the conductive sheet 222. That is, the electrical device can draw power from the phase line of the phase gear. When the phase-shifting toggle member 21 moves to be in contact with the protrusion 1211, the protrusion 1211 pushes the conductive sheet 222, enabling the spring 221 to be compressed for deformation. In this case, the conductive sheet 222 leaves the connecting member 11 and the connecting terminal 312: the conductive sheet 222 is disconnected from both the connecting member 11 and the connecting terminal 312. It should be particularly noted that, when the phase-shifting toggle member 21 moves to the neutral gear, one end of the conductive sheet 222 is located on a side of the connecting terminal 312, and under the elastic action of the spring 221, one end of the conductive sheet 222 is pressed between two adjacent grooves of the phase-shifting guide member 12. In this case, the conductive sheet 222 is not connected to any connecting terminal 312, that is, in a power-off neutral-gear status. In brief, a user toggles the phase-shifting toggle member 21 to move in the toggle slot 231, so as to reach a corresponding phase gear, such that a phase line at this gear position can be selected for power supply, and then to a neutral gear, such that disconnection can be achieved. This can achieve switching for phase shifting of the phase line and neutral gear switching.

[0031] Referring to FIG. 7, FIG. 7 is schematic structural diagram of a connecting member according to an embodiment. Preferably, the connecting member 11 includes a connecting portion 111 and a contact row 112. The connecting portion 111 is electrically connected to the contact row 112, the contact row 112 is disposed at the phase-shifting guide member 12, and the connecting portion 111 is electrically connected to the electrical device. The contact row 112 is disposed along a slot direction of the guide slot 121, and when the phase shifting assembly 2 moves in the guide slot 121, the other end of the phase shifting assembly 2 is in on-off coordination with the contact row 112. During specific application, the connecting portion 111 and the contact row 112 are both made of a conductive material. The contact row 112 is in the shape of a long strip and disposed on a side of the guide slot 121 along a slot direction of the guide slot 121. The plurality of connecting terminals 312 are spaced apart on the other side of the guide slot 121 along the slot direction of the guide slot 121. In other words, the phase-shifting toggle member 21 moves along the slot direction of the guide slot 121.

Optionally, the plug connector for arbitrary phase shifting further includes a housing assembly 4.

In this embodiment, the connecting assembly 1, the phase-line terminal member 31, the non-phase line terminal member 32, and the conductive sheet 222 are merely made of a conductive material, and the other components are made of an insulating material. The phase-line terminal member 31 and the non-phase line terminal member 32 are apart from each other in the housing assembly 4, and an insulating housing is disposed between the phase-line terminal member 31 and the non-phase line terminal member 32 for separation, ensuring no contact therebetween, thus improving the safety. Specifically, a plurality of gear indicators are disposed on the housing assembly 4 and respectively correspond to a plurality of phase gears and a plurality of neutral gears. For example, L1, L2, and L3 may be used as gear indicators for three phase gears, and neutral gear may be represented by N, representing a neutral position. It can be understood that when the phase shifting assembly 2 moves to be directly opposite the corresponding gear indicator, it is right at a corresponding gear. In this way, it is intuitive for the user to know about the gear switching situation, thus improving the product practicability.Embodiment 2:

[0034] A lamp in this embodiment includes the plug connector for arbitrary phase shifting in Embodiment 1, a lamp body, and a connecting wire harness. Two ends of the connecting wire harness are electrically connected to the connecting assembly 1 of the plug connector for arbitrary phase shifting and the lamp body, respectively. During specific application, lines of an external power source such as a phase line and a neutral line only need to be connected to the terminal assembly 3 for use, improving the mounting efficiency. Certainly, in other embodiments, the plug connector for arbitrary phase shifting may be alternatively integrated on another electrical device, to reduce the mounting difficulty and improve the mounting efficiency.

[0035] In summary, after the plug connector for arbitrary phase shifting is mounted on a line, the phase shifting assembly is arranged and moved to enable one end thereof to be electrically connected to one of the phase-line terminal members, achieving that one of three phase lines is selected for connection. In this way, the power phase shifting can be achieved. Any phase line can be selected based on the actual situation to provide electric energy. This is equivalent to integrating the power phase shifting function on a connector without the need to mount both the connector and a phase shifter on the same line. This simplifies the line structure, reduces the line connection difficulty, and improves the mounting efficiency. During use, the connecting assembly only needs to be connected to the electrical device, and the phase-line terminal member is connected to the phase line. The phase shifting assembly is moved to be connected to one of the phase lines selected, so as to provide electric energy to the electrical device, thus achieving power phase shifting. This embodiment features a simple structure, low manufacturing costs, and a fast mounting speed, is suitable for a three-phase line in any manner, and has wide application scenes.
