Description

Technical Field

[0001] The present invention relates to the technical field of power taking structures, and in particular to a power taking plug structure and a power taking system. Background Art

[0002] There are many wires on the ceiling of the supermarket, including sensor wires, camera wires, central emergency, DALI control, etc., and the lamps may integrate emergency, sensing, DALI control and other functions, which requires the lamps to have more wire interfaces.

[0003] An electrical track is a track system used to install and fix lamps and other electrical equipment, with multiple wires arranged inside for power supply and control. A wire trough is a groove or channel inside an electrical track used to accommodate and fix wires, and each wire in the electrical track is arranged in a separate wire trough. As lamps have more functions, more wires are required, resulting in more wires and wire troughs being arranged in the electrical track. On the basis of the unchanged width of the electrical track, the more wire troughs there are, the smaller its width will be. Currently, power plugs are usually arranged at intervals along the width direction, and the power extraction piece on the power plug itself has a certain width. When the width of the wire trough is limited and the spacing between two adjacent wire troughs is small, the power extraction pieces of two adjacent power plugs are prone to touch, posing a risk of short circuit. Summary of the invention

[0004] In view of this, the present invention provides a power plug structure and a power supply system to solve the problem that the current power plug has a short circuit risk when the width of the wire slot is limited and the distance between two adjacent wire slots is small.

[0005] The present invention provides a power plug structure, comprising:

[0006] Plug housing;

[0007] A circuit board assembly, the circuit board assembly is arranged in the plug housing, and the circuit board assembly is used to provide a wire interface;

[0008] Multiple rows of plug assemblies, each row of the plug assemblies includes at least one plug assembly, and the plug assemblies in different rows are staggered in the width direction; one end of the plug assembly is electrically connected to the circuit board assembly, and the other end of the plug assembly is electrically connected to the conductive structure in the wire groove of the electrical track.

[0009] The beneficial effects of the above-mentioned power plug structure are:

[0010] The staggered arrangement of plug assemblies in different rows in the width direction can reduce interference between adjacent plug assemblies. Even if the wire groove width of the electrical track is small, it can ensure that each plug assembly can make good contact with the conductive structure of the electrical track. The staggered arrangement design of multiple rows of plug assemblies makes full use of the space of the plug housing, making the overall structure more compact and suitable for use in limited spaces. The staggered arrangement of plug assemblies can reduce the risk of short circuits between adjacent plug assemblies and ensure the safe operation of the electrical system.

[0011] In an optional embodiment, the plug assemblies in different rows are staggered in the height direction. The staggered arrangement design in the height direction can more reasonably utilize the space of the plug housing, so that each plug assembly has enough space for installation and connection without excessive compression in the width direction. And even if the width of the wire trough is limited, the plug assemblies can be staggered in the height direction to avoid mutual interference in the width direction, so that each plug assembly can be smoothly inserted into the wire trough.

[0012] Correspondingly, different rows of wire ducts and conductive structures are also staggered in the height direction, so that different rows of plug assemblies can abut against conductive structures at different heights, effectively reducing the risk of short circuits between adjacent rows of plug assemblies and ensuring safe operation of the electrical system.

[0013] In an optional embodiment, the circuit board assembly includes:

[0014] A circuit board, wherein a plurality of rows of gold finger areas are arranged on the circuit board, and each of the gold finger areas is electrically connected to a plug assembly;

[0017] In an optional embodiment, the plug housing includes a plug body and a plug cover which are detachably connected to each other, and one side of the plug body is open. A plurality of partitions extending to the side opening are provided on the plug body, and a receiving groove for accommodating the wiring terminals is formed between two adjacent partitions, and the wire interface is formed between the receiving groove and the circuit board.

[0018] In an optional embodiment, the plug assembly includes a plug and a power-taking spring, the plug is arranged on the plug housing, the power-taking spring is arranged inside the plug, one end of the power-taking spring is electrically abutted against the circuit board assembly, and the other end of the power-taking spring extends from the plug and electrically abuts against the conductive structure in the wire groove of the electrical track.

[0019] In the above-mentioned plug assembly, the power spring can be a flexible conductive wire / column / rod. The design of the power spring can ensure that it maintains a good electrical connection between the circuit board assembly and the conductive structure in the wire groove of the electrical track. The elastic properties of the power spring can ensure that the contact points are always in close contact, reducing the risk of poor contact. The power spring occupies a small volume, and even if the width of the wire groove is small, the power spring can effectively abut against the conductive structure in the wire groove, which is suitable for use in limited space.

[0020] In an optional embodiment, a long hole is opened through the inside of the plug, and an abutment plate is arranged in the long hole. The abutment plate divides the long hole into an abutment groove and a through hole. The abutment groove is located at the end of the plug away from the electrical track, and the through hole passes through the plug.

[0021] In an optional embodiment, the power-taking spring includes a first conductive part, an abutment part, and a second conductive part which are connected in sequence, the first conductive part is electrically abutted against the circuit board assembly, the abutment part is arranged in an abutment groove and is adapted to the abutment plate, the second conductive part is arranged in a through hole and extends from the through hole, and the second conductive part is electrically abutted against the conductive structure in the wire groove of the electrical track.

[0022] The abutment portion of the power taking spring is arranged in the abutment groove and matched with the abutment plate, which ensures that the power taking spring is fixed in position inside the plug and reduces poor contact caused by vibration or movement. The segmented design of the first conductive portion, the abutment portion and the second conductive portion enables each portion to better adapt to different areas inside the plug.

[0023] When the plug is inserted into the wire slot, the electrical contact between the first conductive part and the circuit board assembly and the electrical contact between the second conductive part and the conductive structure in the wire slot of the electrical track can be completed simultaneously, thereby improving the plugging and unplugging speed and efficiency.

[0024] In an optional embodiment, the first conductive portion is configured to be in the shape of a hook with an opening facing away from the circuit board assembly;

[0026] The second conductive portion is configured to be in a hook shape with an opening facing away from the conductive structure.

[0027] In an optional implementation, the power taking spring is made of copper alloy.

[0028] The power spring is a molded specific elastic structure with good resilience to ensure the reliability of power supply. The power spring is both a conductor and a spring. Because the power spring is a copper alloy rod with high strength, the volume of the power spring can be very small. It can be made into a multi-position terminal under a certain volume. It is suitable for use in situations where the structural volume is required to be high, and the process is simple.

The gradual width design allows the plug to adapt to wire grooves of different widths, especially wire grooves with smaller widths, thereby increasing the scope of application of the plug.

[0030] In an optional embodiment, at least one of the plug assemblies is configured to be movable, and when the plug assembly moves, the circuit board assembly circuit can be switched.

[0031] The mobility of the plug assembly allows the user to dynamically adjust the position of the plug according to actual needs, thereby realizing flexible switching of the circuit board assembly circuit, enabling the device to adapt to different usage scenarios and needs, and improving the adaptability and flexibility of the system.

When the plug slides along the slide rail to different groove positions, the power extraction spring is electrically connected to different gears of the circuit board assembly.

[0034] The protrusion on the plug is matched with the groove on the side wall of the slide rail, ensuring that the plug can be accurately aligned when sliding to a specific position, avoiding circuit connection errors caused by position deviation.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] There are many wires on the ceiling of the supermarket, including sensor wires, camera wires, central emergency, DALI control, etc., and the lamps may integrate emergency, sensing, DALI control and other functions, which requires the lamps to have more wire interfaces.

[0054] An electrical track is a track system used to install and fix lamps and other electrical equipment, with multiple wires arranged inside for power supply and control. A wire trough is a groove or channel inside an electrical track used to accommodate and fix wires, and each wire in the electrical track is arranged in a separate wire trough. As the number of wires required increases with the number of functions of the lamp, more wires are required, resulting in more wires and wire troughs being arranged in the electrical track. On the basis of the unchanged width of the electrical track, the more wire troughs there are, the smaller its width will be. At present, power plugs are usually arranged at intervals along the width direction, and the power extraction plates on the power plugs have a certain width. When the width of the wire trough is limited and the spacing between two adjacent wire troughs is small, the power extraction plates of two adjacent power plugs are prone to touch, posing a risk of short circuit. Moreover, it is difficult to achieve a large number of arrangements when the track width is limited.

[0055] Based on the fact that lamps have more functions, the applicant has developed an electrical track with compactly arranged wire ducts. Due to the limited width of the wire ducts, it is necessary to design a larger number of wiring terminals into it within a certain size. The space occupied by each terminal must be very small, and it must comply with safety regulations, be capable of automated production, and have the lowest possible cost.

[0056] Based on this, the present invention provides a power plug structure, in which plug assemblies in different rows are staggered in the width direction, which can reduce interference between adjacent plug assemblies. Even if the wire groove width of the electrical track is small, it can ensure that each plug assembly can have good contact with the conductive structure of the electrical track, which is suitable for use in limited space.

[0057] Furthermore, the present invention installs a larger number of connection terminals on the circuit board, which can meet the installation requirements of a larger number of connection terminals.

[0058] In addition, if the spacing between the power strips on the traditional power plug is too small, it is easy to cause short circuits or arc discharges between adjacent power strips, affecting the stability of the electrical connection. In addition, the power strips are not elastic enough. After long-term use, the conductive structure of the power strips and the electrical track is prone to poor contact, affecting the stability of the electrical connection.

[0059] When the spacing between wire slots is small, electrical safety needs to be ensured, the power supply structure needs to maintain a reasonable spacing, and the power supply plug structure needs to provide a stable connection under the premise of a small size of the wire slot. Based on this, the present invention uses a power supply spring to supply electricity. On the one hand, the power supply spring can adapt to compactly arranged wire slots, and a larger spacing can be left between the power supply springs, which can effectively avoid the problem of short circuit between two adjacent socket assemblies; on the other hand, the power supply spring has good resilience. When the power supply plug structure is inserted into the electrical track, the power supply spring can be in close contact with the conductive structure in the electrical track to ensure the stability of the conduction. After long-term use, the power supply spring can still be stably connected to the circuit board assembly and the conductive structure.

[0060] Combine the following Figures 1 to 9 , the power taking plug structure of the first aspect of the present invention and the power taking system of the second aspect of the present invention are elaborated in detail.

[0061] According to an embodiment of the present invention, in a first aspect, a power plug structure is provided, Figures 1 to 7 As shown, it includes a plug housing, a circuit board assembly and a plug assembly. The circuit board assembly is arranged in the plug housing, and the circuit board assembly is used to provide a wire interface 16. The plug assembly is arranged in multiple rows along the length direction, each row of the plug assembly includes at least one plug assembly, and the plug assemblies in different rows are staggered in the width direction. One end of the plug assembly is electrically connected to the circuit board assembly, and the other end of the plug assembly is electrically connected to the conductive structure 72 in the wire groove 71 of the electrical track 7.

[0062] In this embodiment, the plug assemblies in different rows are arranged in a staggered manner in the width direction, which can reduce the interference between adjacent plug assemblies. Even if the width of the wire groove 71 of the electrical track 7 is small, it can ensure that each plug assembly can make good contact with the conductive structure 72 of the electrical track 7. The staggered arrangement design of multiple rows of plug assemblies makes full use of the space of the plug housing, making the overall structure more compact, suitable for use in a limited space, and can achieve a large number of arrangements. The staggered arrangement of plug assemblies can also reduce the risk of short circuits between adjacent plug assemblies, ensuring the safe operation of the electrical system.

[0063] The design of the multi-row plug assembly of this embodiment can adapt to different types of electrical tracks and conductive structures and is suitable for a variety of application scenarios. Plug assemblies of different quantities and arrangements can be selected according to actual needs to meet the needs of different electrical equipment.

[0064] In some embodiments, the plug assemblies in different rows are staggered in the height direction. The staggered arrangement design in the height direction can more reasonably utilize the space of the plug housing, so that each plug assembly has enough space for installation and connection without excessive compression in the width direction. Even if the width of the wire slot is limited, the plug assemblies can be staggered in the height direction to avoid mutual interference in the width direction, so that each plug assembly can be smoothly inserted into the wire slot.

[0065] Correspondingly, different rows of wire ducts and conductive structures 72 are also staggered in the height direction, so that different rows of plug assemblies can abut against conductive structures 72 at different heights, effectively reducing the risk of short circuits between adjacent rows of plug assemblies and ensuring safe operation of the electrical system.

[0066] In some embodiments, in combination Figure 2 As shown, the circuit board assembly includes a circuit board 4 and a connection terminal 5. A plurality of rows of gold finger areas 41 are arranged on the circuit board 4, and each gold finger area 41 is electrically connected to a plug assembly. The gold finger area 41 is used to ensure that the power taking spring takes power from the circuit board during the rebound process.

[0067] There are multiple connection terminals 5, each of which is arranged on the circuit board 4 and electrically connected to a gold finger area 41. More specifically, the connection terminal 5 is electrically connected to the gold finger area 41 through a line arranged along the length direction. The connection terminal 5 is exposed from the side of the plug housing.

[0068] In this embodiment, the design of multiple rows of gold finger areas 41 fully utilizes the space on the circuit board 4, making the entire circuit board assembly more compact and suitable for use in a limited space. Each terminal 5 can be electrically connected to a plug assembly through a gold finger area 41, thereby realizing electrical connection between the terminal 5 and the conductive structure 72 of a wire slot.

[0069] In some embodiments, each terminal block 5 is arranged on the circuit board 4 along the length direction. Multiple rows of sockets 17 are arranged on the plug housing, and each row of sockets 17 is staggered in the width direction. The sockets 17 correspond to the terminal blocks 5, and the sockets 17 are used to provide a housing space for the clamping assembly for limiting the terminal blocks 5, thereby ensuring the fixation of the terminal blocks 5 in the plug housing, enhancing the mechanical stability, and reducing the poor electrical connection caused by the loosening of the terminal blocks 5. For example, the sockets 17 can be used as buckle grooves to prevent the terminal blocks from falling out.

[0070] In some embodiments, the plug housing includes a plug body 1 and a plug cover 6 that are detachably connected to each other, making the assembly and maintenance of the plug assembly more convenient. The user can easily open the plug cover 6 to inspect, replace or repair the internal components. The plug body 1 and the plug cover 6 are both made of insulating materials to play an insulating role. More specifically, the plug body 1 and the plug cover 6 are both made of plastic. The plug cover 6 is used to support the circuit board when the compression force of the power spring 3 is transmitted to the circuit board when the power is taken out.

[0071] Combination Figure 3 As shown, one side of the plug body 1 is open, and a plurality of partitions 14 extending to the side opening are provided on the plug body 1. A receiving groove 15 for receiving the wiring terminal 5 is formed between two adjacent partitions 14, so as to ensure that the wiring terminal 5 is fixed in the plug housing and reduce poor electrical connection caused by looseness. A wire interface 16 is formed between the receiving groove 15 and the circuit board 4. After the wire is inserted into the wire interface 16, the wire can be electrically connected to the wiring terminal 5. The design of the receiving groove 15 and the wire interface 16 makes the connection between the wiring terminal 5 and the circuit board 4 more orderly and more reasonable in layout.

[0072] A plug plate 141 is also provided at the bottom end of the partition 14, and a plurality of plug holes 61 are provided at the top end of the side wall of the plug cover 6. Each plug plate 141 corresponds to the position of a plug hole 61. The plug plate 141 is inserted into the plug hole 61 to realize the positioning of the plug body 1 and the plug cover 6.

[0073] The plug cover plate 6 is also provided with a plurality of supporting ribs 62 to strengthen the connection.

[0074] In some embodiments, the plug assembly includes a plug 2 and a power-taking spring 3, the plug 2 is arranged on the plug housing, the power-taking spring 3 is arranged inside the plug 2, one end of the power-taking spring 3 is electrically abutted against the circuit board assembly, and the other end of the power-taking spring 3 extends from the plug 2 and is electrically abutted against the conductive structure 72 in the wire groove 71 of the electrical track 7.

[0075] In this embodiment, the power spring 3 can be a flexible conductive wire / column / rod. The design of the power spring 3 can ensure that it maintains a good electrical connection between the circuit board assembly and the conductive structure 72 in the wire groove 71 of the electrical track 7. The elastic properties of the power spring 3 can ensure that the contact point is always in close contact, reducing the risk of poor contact. The power spring 3 occupies a small volume, and even if the width of the wire groove is small, the power spring 3 can effectively abut against the conductive structure 72 in the wire groove, which is suitable for use in limited space.

[0076] It should be noted that if only the traditional conductive sheet is replaced with a conductive wire, the conductive wire is easily deformed by external force, resulting in poor contact between it and the circuit board assembly and the conductive structure 72. The power-taking spring 3 in this embodiment is a molded specific elastic structure with good resilience, thereby ensuring the reliability of power taking. The material of the power-taking spring 3 is copper alloy, which has high strength. After the power-taking spring 3 is installed, the power-taking spring 3 can maintain long-term conductive contact with the conductive structure 72 and the circuit board assembly by using its own elasticity and strength, providing working stability.

[0077] The power taking spring is both a conductor and a spring. Since the power taking spring 3 is a copper alloy rod with high strength, the volume of the power taking spring 3 can be very small. It can be made into a multi-position terminal under a certain volume, which is suitable for use in situations where the structural volume is required to be high, and the process is simple.

[0078] The power spring is suitable for low-voltage power rails and can also be used for high-voltage power rails. When the power spring is used for high-voltage power rails, the diameter of the power spring can be increased to a certain extent to adapt to large current intensity.

[0079] In some embodiments, in combination Figure 3 , Figure 5 and Figure 6 As shown, a long hole 23 is opened inside the plug 2, and an abutment plate 24 is arranged inside the long hole 23. The abutment plate 24 divides the long hole 23 into an abutment groove 27 and a through hole 25. The abutment groove 27 is located at the end of the plug 2 away from the electrical track 7, and the through hole 25 passes through the plug 2.

[0080] In this embodiment, the design of the abutment plate 24 can provide a fixed support point, so that the power extraction spring 3 is more stable inside the plug 2 and the risk of loosening is reduced.

[0081] In some embodiments, in combination Figure 4 As shown, the power-taking spring 3 includes a first conductive part 31, an abutting part 32 and a second conductive part 33 which are connected in sequence. The power-taking spring 3 is composed of a bent conductive wire. The first conductive part 31 is electrically abutted against the circuit board assembly. The abutting part 32 is arranged in the abutting groove 27 and is adapted to the abutting plate 24. The second conductive part 33 is arranged in the through hole 25 and extends out from the through hole 25. The second conductive part 33 is electrically abutted against the conductive structure 72 in the wire groove 71 of the electrical track 7.

[0082] In this embodiment, the abutment portion 32 is disposed in the abutment groove 27 and matches the abutment plate 24, ensuring that the position of the power taking spring 3 inside the plug 2 is fixed, reducing poor contact caused by vibration or movement. The segmented design of the first conductive portion 31, the abutment portion 32, and the second conductive portion 33 allows each portion to better adapt to different areas inside the plug 2.

[0083] When the plug is inserted into the wire slot, the electrical contact between the first conductive part 31 and the circuit board assembly and the electrical contact between the second conductive part 33 and the conductive structure 72 in the wire slot 71 of the electrical track 7 can be completed simultaneously, thereby improving the plugging and unplugging speed and efficiency.

[0084] More specifically, combined with Figure 5 and Figure 8 As shown, the first conductive portion 31 is configured to be a hook shape with an opening facing away from the circuit board assembly. The second conductive portion 33 is configured to be a hook shape with an opening facing away from the conductive structure 72. Specifically, the second conductive portion 33 is configured to be U-shaped, and the U-shaped opening of the second conductive portion 33 gradually increases from the side close to the conductive structure to the side away from the conductive structure. The abutment portion 32 includes a first conductive arc segment 321 and a second conductive arc segment 322 connected therebetween, the first conductive arc segment 321 is connected to the first conductive portion 31, and the second conductive arc segment 322 is connected to the second conductive portion 33. Correspondingly, a portion of the abutment plate 24 is also configured to be two arcs, and the abutment plate 24 has a first arc segment 241 and a second arc segment 242. The openings of the first conductive arc segment 321 and the first arc segment 241 face the circuit board assembly, and the openings of the second conductive arc segment 322 and the second arc segment 242 face away from the circuit board assembly.

[0085] When the power-taking spring 3 is installed in place, the first arc segment 241 of the abutment plate 24 can always produce a squeezing force on the first conductive part 31 toward the circuit board assembly, so that the first conductive part 31 can always be in close contact with the circuit board assembly. When the power-taking plug structure is installed on the electrical track 7, the conductive structure on the electrical track 7 produces a downward squeezing force on the second conductive part 33. At this time, the second conductive part 33 moves downward. After the second conductive part 33 moves downward, due to the elastic effect of the power-taking spring 3, the second conductive part 33 of the power-taking spring 3 has an upward movement trend, and can then be in close contact with the conductive structure on the electrical track 7, achieving stability and reliability in power taking.

[0086] In some embodiments, the abutment groove 27 and the through hole 25 in the plug 2 are opened along the length direction, and the width of the abutment groove 27 and the through hole 25 is slightly larger than the outer diameter of the power spring 3 (specifically, the outer diameter of the cross-section circle after the power spring 3 is cut). The first conductive portion 31, the abutment portion 32 and the second conductive portion 33 of the power spring 3 are also arranged along the length direction. In the above technical solution, the overall width of the power spring 3 after being positioned in the plug 2 is relatively small, which is very suitable for the scene where the width of the wire groove on the electrical track is relatively small.

[0087] In some embodiments, in combination Figure 6As shown, the plug 2 includes a plug-in portion 21 and a fixed portion 22. The fixed portion 22 is positioned on the plug housing. The plug-in portion 21 is connected to the fixed portion 22 and inserted into the wire groove 71 of the electrical track 7. The width of the plug-in portion 21 gradually decreases from the side away from the electrical track 7 to the side close to the electrical track 7.

[0088] In this embodiment, the width of the plug portion 21 gradually decreases from the side away from the electrical track 7 to the side close to the electrical track 7, forming a wedge-shaped structure, so that the plug 2 can be inserted into the wire groove 71 of the electrical track 7 more smoothly, reducing resistance and jamming during the insertion process. The gradual width design allows the plug 2 to adapt to wire grooves of different widths, especially wire grooves with smaller widths, thereby increasing the scope of application of the plug 2.

[0089] In some embodiments, at least one plug assembly is configured to be movable, and when the plug assembly moves, the circuit board assembly circuit can be switched.

[0090] In this embodiment, the mobility of the plug assembly allows the user to dynamically adjust the position of the plug according to actual needs, thereby realizing flexible switching of the circuit board assembly circuit, enabling the device to adapt to different usage scenarios and needs, and improving the adaptability and flexibility of the system. By moving the plug assembly, the user can easily switch different circuit functions, allowing a single device to achieve multiple functions.

[0091] More specifically, a sliding hole 13 and a sliding rail 11 are provided on the plug housing. The plug 2 is slidably provided on the sliding rail 11, and the power extraction spring 3 passes through the sliding hole 13. The circuit board assembly located directly below the sliding hole 13 has multiple gears, and when the plug 2 slides to different positions along the sliding rail 11, the power extraction spring 3 is electrically connected to different gears of the circuit board assembly.

[0092] In this embodiment, the user can move the plug 2 along the slide rail 11, thereby driving the power spring 3 to slide in the slide hole 13 to switch between different gears of the circuit board assembly. The user can switch the circuit by simply sliding the plug 2, which is easy to operate, improves the user experience, and has high switching efficiency.

[0093] Combination Figure 3 As shown, a plurality of grooves 12 are provided on the side wall of the slide rail 11. Figure 7 As shown, the plug 2 is provided with a protrusion 26 that can be matched with the groove 12. When the plug 2 slides along the slide rail 11 to different positions of the groove 12, the power extraction spring 3 is electrically connected to different gears of the circuit board assembly.

[0094] In this embodiment, the protrusion 26 on the plug 2 is matched with the groove 12 on the side wall of the slide rail 11, ensuring that the plug 2 can be accurately aligned when sliding to a specific position, avoiding circuit connection errors caused by position deviation. The matching of the protrusion 26 and the groove 12 can also ensure that the plug 2 can be stably fixed when it moves to the position of the groove, reducing the shaking or displacement of the plug 2 during use.

[0095] In some embodiments, the plug housing is further provided with an anti-reverse rib 8, which is provided at a non-middle position of the plug housing, and can be provided specifically between the gaps of two adjacent plug assemblies. In this embodiment, after the anti-reverse rib 8 is provided, the installation method of the power plug structure is unique, and the overall installation direction of the power plug structure is prevented from being reversed.

[0096] The above-mentioned power plug structure is suitable for low-voltage power rails and high-voltage power rails. The power spring 3 is assembled into the electrical rail by utilizing its own elasticity and conductivity. The power spring 3 abuts against the conductive sheet / conductive wire in the rail, and the bottom contacts the circuit board, which can maintain the conductivity stability for a long time. Because of its small size, it is particularly suitable for multi-position wire slots and can provide more connections in the width direction.

[0097] According to an embodiment of the present invention, a second aspect provides a power supply system, Fig. 9 As shown, it includes an electrical track 7 and a power plug structure, and the power plug structure is connected to the electrical track 7. A plurality of wire grooves 71 are provided on the electrical track 7, and a conductive structure 72 is provided in the wire groove 71. The conductive structure 72 is a conductive wire or a conductive sheet. Preferably, the conductive structure 72 is a copper bar, and the power spring 3 on the power plug structure is an elastic copper wire.

[0098] In some embodiments, a plurality of wire grooves 71 are arranged at intervals along the length direction, and two adjacent wire grooves 71 are staggered in the height direction.

[0099] In this embodiment, more wire ducts 71 can be arranged in the same horizontal area through staggered arrangement, thereby improving space utilization. The wire ducts 71 are staggered in height direction, thereby making full use of vertical space, making the internal layout of the device more compact, and saving horizontal space.

[0100] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
