Description

[0001] The present invention relates to the technical field of power supply phase conversion, and in particular to a plug-in connector and a lamp capable of arbitrarily converting phases. Background Art

[0002] With the development of the LED industry, traditional lighting fixtures are gradually being replaced by LED lamps, and LED lamps need to be equipped with LED driver power supplies. LED power supplies have the advantages of outputting constant voltage or outputting constant current, high power factor, high conversion efficiency, long life, and dimmable light, which ensures the high energy saving and stability of LED lamps. LED driver power supplies have been widely used in more and more lighting fixtures.

[0003] Nowadays, most LED drivers are powered by three-phase electricity, which means that any one of the three-phase electricity is connected to the LED driver. In some places where a large number of electrical equipment such as LED lamps need to be installed, it is necessary to consider the relative balance of the load power on the three phases. One way is to pre-design the connection layout on each phase before installing the electrical equipment. This method takes a long time to install and has poor flexibility. If new electrical equipment needs to be added later, it is easy to cause grid instability. Another way is to install connectors and phase shifters on the same line at the same time when arranging the line. Although this can achieve power phase change through the phase shifter, it makes the line structure complicated, takes a lot of time to install, and is inefficient. Summary of the invention

[0031] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0032] Embodiment 1:

[0033] Reference Figure 1-3 , Figure 1 is a schematic diagram of the structure of the connector capable of arbitrarily changing phases in an embodiment, Figure 2is a schematic structural diagram of the arbitrarily phase-shifting plug connector after phase shifting in the embodiment, Figure 3 This is another structural schematic diagram of the arbitrarily phase-rotating plug-in connector after phase rotation in the embodiment. The arbitrarily phase-rotating plug-in connector in this embodiment includes a connecting component 1, a phase-rotating component 2 and a terminal component 3. The connecting component 1 is electrically connected to the electrical equipment. The terminal component 3 includes a plurality of phase line terminal pieces 31, and the phase line terminal pieces 31 are electrically connected to the phase line. The phase-rotating component 2 is movably connected across the connecting component 1 and the plurality of phase line terminal pieces 31. The phase-rotating component 2 is moved so that the two ends of the phase-rotating component 2 are electrically connected or disconnected with the connecting component 1 and one of the phase line terminal pieces 31, respectively.

[0034] Re-reference Figure 1-3 , Figure 1-3 This is a schematic diagram of the structure when switching three different phase lines in this embodiment. The arbitrarily phase-changing plug connector in this embodiment is installed on the line for connecting the electrical equipment with the external power supply. Along the moving direction of the phase-changing component 2, multiple phase-line terminal pieces 31 are arranged in sequence. Move the phase-changing component 2 so that one end of the phase-changing component 2 is electrically connected or disconnected with one of the phase-line terminal pieces 31. In this embodiment, there are three phase-line terminal pieces 31, which are applied to the three-phase power supply. Each phase-line terminal piece 31 is connected to one of the phase lines in the three-phase power supply. In the process of moving the phase-changing component 2, one end of the phase-changing component 2 moves back and forth between the phase-line terminal pieces 31. When one end of the phase-changing component 2 contacts one of the phase-line terminal pieces 31, the phase-changing component 2 electrically connects the phase line of the phase-line terminal piece 31 with the connecting component 1, that is, the phase line on the phase-line terminal piece 31 is connected to the electrical equipment on the connecting component 1 to supply power. When the phase-shifting assembly 2 moves to a point where one end thereof is located at a gap between two adjacent phase-line terminal pieces 31 , the phase-shifting assembly 2 is disconnected from the phase-line terminal pieces 31 and is in a neutral state.

[0035] Among them, after the arbitrarily phase-changing plug-in connector is installed on the line, through the setting of the phase-changing component 2, the phase-changing component 2 is moved so that one end of it is electrically connected to one of the phase line terminal pieces 31, so that one of the three phase lines can be selected for connection, so that the phase of the power supply can be changed. Any phase line can be selected to provide electrical energy according to actual conditions, and the connecting component 1 is electrically connected to electrical equipment such as lamps. It can be understood that the arbitrarily phase-changing plug-in connector in this embodiment is equivalent to integrating the power phase-changing function into the connector, and there is no need to install both the connector and the phase shifter on the same line, which simplifies the line structure, reduces the difficulty of line connection, and improves the installation efficiency. When used, it is only necessary to connect the connecting component 1 to the electrical equipment, and the phase line terminal piece 31 to the phase line. By moving the phase-changing component 2, one of the phase lines can be selected for connection to provide electrical energy to the electrical equipment to achieve power phase change. This embodiment has a simple structure, low manufacturing cost, fast installation speed, and can be adapted to various forms of three-phase lines, and has a wide range of application scenarios.

[0036] Refer to Figure 4 , Figure 4 It is a structural schematic diagram of the terminal assembly in the embodiment. Preferably, the terminal assembly 3 also includes at least one non-phase line terminal piece 32, and the non-phase line terminal piece 32 is spaced apart from the phase line terminal piece 31. The non-phase line terminal piece 32 is used to connect the non-phase line or is in an empty state. In specific applications, the number of non-phase line terminal components 32 in this embodiment is four, and the four non-phase line terminal components 32 and the three phase line terminal components 31 are arranged alternately in sequence. The non-phase line terminal components 32 are used to connect non-phase lines such as neutral lines, ground lines, functional lines, etc. or are in an empty state. The empty state means that no line is connected. It can be understood that when the phase-shifting component 2 moves to face one of the phase line terminal components 31, it is electrically connected to the phase line terminal component 31, that is, the phase line connected to the phase line terminal component 31 is selected to provide electrical energy. When the phase-shifting component 2 moves to face one of the non-phase line terminal components 32, the phase-shifting component 2 and the non-phase line terminal component 32 are not connected to each other, and the phase-shifting component 2 and the phase line terminal component 31 are both in a disconnected state, that is, the phase-shifting component 2 is in an idle state at this time, and the overall circuit is in a power-off state. Of course, in other embodiments, the number of non-phase line terminal components 32 can be one, two, three or even more. A corresponding number of non-phase line terminal components 32 can be set according to actual usage requirements to connect the neutral line, the ground line, other functional lines or not connect any lines.

[0037] Refer to Figure 5 , Figure 5 It is a structural schematic diagram of the phase-shifting guide in the embodiment. Preferably, the connecting component 1 includes a connecting component 11 and a phase-shifting guide 12. The connecting component 11 is arranged on the phase-shifting guide 12. One end of the connecting component 11 is electrically connected to the electrical equipment, and the other end is in on-off coordination with the phase-shifting component 2. The phase-shifting guide 12 is provided with a guide groove 121. The phase-shifting component 2 is movably arranged in the guide groove 121. The guide groove 121 limits and guides the movement of the phase-shifting component 2. When the mobile phase-shifting component 2 is shifted, the phase-shifting component 2 can always move along the groove direction of the guide groove 121 through the setting of the guide groove 121, thereby ensuring the accuracy of the movement of the phase-shifting component 2, thereby ensuring that the mobile phase-shifting component 2 can accurately control its phase-shifting switching. Specifically, the connecting component 11 is a standard part made of conductive materials such as copper, and the phase-shifting guide 12 is made of insulating materials. The guide groove 121 in this embodiment is in a straight line shape, that is, the phase-shifting assembly 2 performs a linear reciprocating movement, and the plurality of phase-line terminal pieces 31 are sequentially arranged in a spaced relationship along the groove direction of the guide groove 121. As the phase-shifting assembly 2 moves, one end of the phase-shifting assembly 2 moves back and forth between the plurality of phase-line terminal pieces 31, thereby achieving connection or disconnection with one of the phase-line terminal pieces 31. In other embodiments, the guide groove 121 may also be in an arc shape or a special shape, which is not limited here.

[0038] Re-reference Figure 1-5 Preferably, a plurality of grooves 123 are provided at one end of the phase-turning guide 12, and the phase-line terminal 31 comprises a terminal body 311 and a connection terminal 312 connected to the terminal body 311. The plurality of terminal bodies 311 are provided at intervals on one side of the phase-turning guide 12 and are electrically connected to a phase line respectively, and the plurality of connection terminals 312 are provided in the plurality of grooves 123 respectively. The phase-turning assembly 2 moves along the groove direction of the guide groove 121. When one end of the phase-turning assembly 2 is directly opposite to one of the grooves 123, the one end of the phase-turning assembly 2 is electrically connected to the connection terminal 312 in the groove 123. When the other end of the phase-turning assembly 2 is offset from the groove 123, the one end of the phase-turning assembly 2 is disconnected from the connection terminal 312. In specific application, the terminal body 311 is located at the bottom of the phase-turning guide 12, and the connecting terminal 312 is arranged at the top of the terminal body 311 and is located in the groove 123. When one end of the phase-turning component 2 moves to the groove 123, one end of the phase-turning component 2 contacts the connecting terminal 312 in the groove 123, thereby realizing electrical connection with one of the phase lines. When one end of the phase-turning component 2 moves between two adjacent grooves 123, one end of the phase-turning component 2 is staggered from the connecting terminal 312, and is in a neutral state, that is, the power is disconnected. Specifically, the terminal body 311 and the connecting terminal 312 are an integrated structure and can be made of conductive materials such as copper. The non-phase line terminal piece 32 is similar in structure to the phase line terminal piece 31, and both are made of conductive materials such as copper, but the non-phase line terminal piece 32 has a terminal body but no connecting terminal, so that the entire non-phase line terminal piece 32 is located at the bottom of the phase-turning guide 12.

[0039] Re-reference Figure 1-5Preferably, along the groove direction of the guide groove 121, a plurality of spaced protrusions 1211 are provided in the guide groove 121, and a plurality of phase terminal pieces 31 are respectively opposite to the gap between two adjacent protrusions 1211. The phase shift assembly 2 moves along the groove direction of the guide groove 121. When the phase shift assembly 2 contacts the protrusion 1211, the phase shift assembly 2 is disconnected from the phase terminal piece 31. When the phase shift assembly 2 is located in the gap, the phase shift assembly 2 is electrically connected to one of the phase terminal pieces 31. Through the setting of the protrusion 1211, during the movement of the phase shift assembly 2, when the phase shift assembly 2 moves to the protrusion 1211, the protrusion 1211 lifts the phase shift assembly 2, so that the two ends of the phase shift assembly 2 are respectively separated from the phase terminal piece 31 and the connection assembly 1, so that the entire circuit can be disconnected. It should be particularly noted that, in this embodiment, the phase line terminal 31 is opposite to the gap between two adjacent protrusions 1211, that is, it is opposite to the depression between two adjacent protrusions 1211. That is to say, when the phase shift assembly 2 is connected to one of the phase line terminal pieces 31, the phase shift assembly 2 is located in the depression between the two protrusions 1211. The two adjacent protrusions 1211 fix the relative position of the phase shift assembly 2, so that when it is connected to the phase line terminal piece 31, it is stuck between the two protrusions 1211 without shaking, thereby ensuring the stability of the connection. In short, the depression formed between two adjacent protrusions 1211 can be regarded as a gear position. When the depression is opposite to the phase line terminal piece 31, the depression can be regarded as a phase line gear position. When the phase shift assembly 2 moves to this gear position, the phase line on the phase line terminal piece 31 supplies power to the electrical equipment. When the depression is not directly opposite to the phase terminal 31, the depression can be regarded as a neutral position. When the phase shift assembly 2 moves to this position, the phase shift assembly 2 is disconnected from the phase terminal 31, and the line is in a disconnected state. In this embodiment, the three phase terminal pieces 31 correspond to three phase positions, while the non-phase terminal pieces 32 correspond to neutral positions. In this embodiment, the phase positions and neutral positions are alternately arranged in sequence. When used, the phase shift assembly 2 can be moved to the corresponding position according to the use requirements, thereby realizing the three-phase power supply phase switching and neutral position switching, which is simple to use. Of course, in other embodiments, the number and arrangement order of the phase positions and neutral positions can be adjusted accordingly according to actual needs.

[0040] Refer to Figure 6 , Figure 6Schematic diagram of the structure of the phase shift assembly in the embodiment. Preferably, the phase shift assembly 2 includes a phase shift dial 21, an elastic conductive member 22 and a pressure cover 23. The elastic conductive member 22 is connected to the phase shift dial 21. The elastic conductive member 22 is movably arranged in the guide groove 121. The pressure cover 23 is arranged on the phase shift guide 12 and presses the elastic conductive member 22 against the guide groove 121. The pressure cover 23 is provided with a dial groove 231 directly opposite to the guide groove 121. The phase shift dial 21 is movably arranged in the dial groove 231. The phase shift dial 21 is moved in the dial groove 231 to drive the elastic conductive member 22 to move synchronously in the guide groove 121. When the elastic conductive member 22 moves to contact with the protrusion 1211, the elastic conductive member 22 is disconnected from the phase line terminal 31. When the elastic conductive member 22 moves to the gap, the elastic conductive member 22 is electrically connected to one of the phase line terminal 31. In specific applications, the elastic conductive member 22 includes a spring 221 and a conductive sheet 222, and the two ends of the spring 221 are respectively connected to the phase-shifting dial member 21 and the conductive sheet 222. The spring 221 can also be replaced by other elastic components. When the phase-shifting dial member 21 moves to the phase line position, under the elastic force of the spring 221, the conductive sheet 222 is tightly pressed against the connector 11 and the connecting terminal 312, thereby improving the stability of the connection between the conductive sheet 222 and the connecting terminal 312. The connector 11 and the connecting terminal 312 are electrically connected through the conductive sheet 222, that is, the electrical equipment can draw electricity from the phase line of the phase line position. When the phase-shifting dial member 21 moves to contact with the protrusion 1211, the protrusion 1211 pushes the conductive sheet 222 so that the spring 221 is compressed and deformed. At this time, the conductive sheet 222 is away from the connector 11 and the connecting terminal 312, and the conductive sheet 222 is disconnected from the connector 11 and the connecting terminal 312. It should be noted that when the phase-changing dial 21 moves to the neutral position, one end of the conductive sheet 222 is located on one side of the connection terminal 312, and one end of the conductive sheet 222 is pressed between two adjacent grooves of the phase-changing guide 12 under the elastic force of the spring 221. At this time, the conductive sheet 222 is not connected to any connection terminal 312, that is, it is in a power-off neutral state. In short, the user moves the phase-changing dial 21 in the dial slot 231, and when it moves to the corresponding phase line gear position, the phase line of the gear position can be selected for power supply, and when it moves to the neutral position, the connection can be disconnected, so that the phase line phase switching and neutral switching can be realized.

[0041] Refer to Figure 7 , Figure 7It is a structural schematic diagram of the connector in the embodiment. Preferably, the connector 11 includes a connecting portion 111 and a contact row 112. The connecting portion 111 and the contact row 112 are electrically connected. The contact row 112 is arranged on the phase-changing guide 12. The connecting portion 111 is electrically connected to the electrical equipment. The contact row 112 is arranged along the groove direction of the guide groove 121. When the phase-changing component 2 moves in the guide groove 121, the other end of the phase-changing component 2 is connected and disconnected with the contact row 112. In specific applications, the connecting portion 111 and the contact row 112 are both made of conductive material. The contact row 112 is in the shape of a long strip and is arranged on one side of the guide groove 121 along the groove direction of the guide groove 121. A plurality of connecting terminals 312 are arranged in sequence and spaced apart on the other side of the guide groove 121 along the groove direction of the guide groove 121. That is to say, the phase-changing code member 21 moves along the groove direction of the guide groove 121, and 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 switching. The other end of the conductive sheet 222 moves back and forth along the length direction of the contact row 112, and the on-off coordination with the contact row 112 is achieved by lifting the protrusion 1211.

[0042] Re-reference Figure 7 Preferably, mounting blocks 1121 are respectively provided at both ends of the contact row 112, and mounting holes 122 are provided at positions corresponding to the mounting blocks 1121 of the phase-changing guide 12, and the mounting blocks 1121 are snapped into the mounting holes 122, so that the contact row 112 is snapped into and mounted on the phase-changing guide 12. By setting the mounting blocks 1121 and the mounting holes 122, the contact row 112 can be stably mounted on the phase-changing guide 12, thereby improving the stability of the installation and ensuring that it does not shake during use. Specifically, the connecting portion 111 is a clamp-shaped structure, which is used to clamp the wiring harness of the electrical equipment and to achieve electrical connection with the contact row 112.

[0043] Refer to Figure 8-9 , Figure 8 The schematic diagram of the structure of the arbitrarily phase-rotating pluggable connector with a housing assembly in the embodiment is shown in FIG. Fig. 9It is another structural schematic diagram of the arbitrarily phase-changing plug-in connector with a shell assembly in the embodiment. Preferably, the arbitrarily phase-changing plug-in connector also includes a shell assembly 4, a connecting assembly 1 is arranged in the shell assembly 4, a wiring harness of the electrical equipment extends into the shell assembly 4 and is electrically connected to the connecting assembly 1, a phase-changing assembly 2 is movably arranged in the shell assembly 4, one end of a plurality of phase-line terminal pieces 31 is connected and disconnected with the phase-changing assembly 2, and the other end extends outward from the shell assembly 4 and is electrically connected to a phase line respectively. In specific applications, the shell assembly 4 is made of insulating material. In this embodiment, only the connecting assembly 1, the phase-line terminal piece 31, the non-phase-line terminal piece 32 and the conductive sheet 222 are conductive materials, and they are all made of insulating materials. The phase-line terminal piece 31 and the non-phase-line terminal piece 32 are arranged at intervals in the shell assembly 4, and the phase-line terminal piece 31 and the non-phase-line terminal piece 32 are separated by an insulating shell to ensure that they do not contact each other, thereby improving safety. Specifically, the shell assembly 4 is provided with a plurality of gear marks, and the plurality of gear marks correspond to a plurality of phase line gears and a plurality of neutral gear settings, respectively. For example, the three phase line gears can use L1, L2 and L3 as gear marks, and the neutral gear can use N to represent the neutral line gear, etc. It can be understood that when the phase shift assembly 2 moves to face the corresponding gear mark, it represents which corresponding gear it is in at this time, so that the user can intuitively understand the gear switching situation, thereby improving the practicality of the product.

[0044] Embodiment 2:

[0045] The lamp in this embodiment includes the arbitrarily phase-changing plug connector in the first embodiment, the lamp body and the connecting harness, and the two ends of the connecting harness are electrically connected to the connecting component 1 of the arbitrarily phase-changing plug connector and the lamp body respectively. In specific applications, it is only necessary to connect the phase line and the neutral line of the external power supply to the terminal assembly 3 before it can be put into use, thereby improving the installation efficiency. Of course, in other embodiments, the arbitrarily phase-changing plug connector can also be integrated into other electrical equipment to reduce the difficulty of installation and improve the installation efficiency.

[0046] To summarize, after the phase-changing plug-in connector is installed in the circuit, the phase-changing component can be set to move one end of the phase-changing component to electrically connect one of the phase line terminal pieces, so that one of the three phase lines can be selected for connection. In this way, the phase of the power supply can be changed, and any phase line can be selected to provide electrical energy according to actual conditions. At the same time, it is equivalent to integrating the power phase-changing function into the connector, and there is no need to install both the connector and the phase shifter on the same circuit, which simplifies the circuit structure, reduces the difficulty of circuit connection, and improves the installation efficiency. When used, it is only necessary to connect the connecting component to the electrical equipment and the phase line terminal piece to the phase line. By moving the phase-changing component, one of the phase lines can be selected for connection to provide electrical energy to the electrical equipment to achieve power phase change. This embodiment has a simple structure, low manufacturing cost, fast installation speed, and can be adapted to various forms of three-phase lines, and has a wide range of application scenarios.

[0047] The above is only the implementation mode of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
