[0002] A Power Plug Structure and Power-Taking System

[0003] This present application claims priority of Chinese patent application no. CN 202411731462.0 filed on Nov. 28, 2024, the disclosures of which are incorporated herein by reference in its entirety.

[0004] Field of Invention

[0005] The present disclosure relates to the technical field of power-taking structures, and specifically relates to a power plug structure and a power-taking system.

[0006] Background of Invention

[0007] There are many wires on the top of supermarkets, including sensor wires, camera wires, central emergency wires, DALI control wires, etc. Lamps may integrate functions such as emergency, induction, and DALI control, which requires more wire interfaces for the lamps.

[0008] An electrical track is a track system for installing and fixing lamps and other electrical equipment, with multiple wires arranged inside for power supply and control. A wire slot is a groove or channel inside the electrical track for accommodating and fixing wires, and each wire in the electrical track is arranged in an independent wire slot. As functions of lamps are increasing, more wires are needed, resulting in more wires and wire slots arranged in the electrical track. On the basis that the width of the electrical track remains unchanged, the more the number of wire slots, the smaller their width will be. Current power plugs are usually arranged at intervals along the width direction, and the power-taking pieces on the power plugs themselves have a certain width. When the width of the wire slots is limited and the distance between two adjacent wire slots is small, the power-taking pieces of two adjacent power plugs are prone to contact, posing a risk of short circuit.

The width of the plug-in part gradually decreases from the side far away from the electrical track to the side close to the electrical track, forming a wedge-shaped structure. This structure makes the plug insert into the wire slot of the electrical track more smoothly, reducing resistance and jamming during insertion. The gradually changing width design allows the plug to adapt to wire slots of different widths, especially those with small widths, which improves the application range of the plug.

[0042] Detailed description of preferred embodiments

[0043] Specific embodiments of the present disclosure will be further described in detail below based on the accompanying drawings. It should be understood that the descriptions of the embodiments of the present disclosure herein are not intended to limit the protection scope of the present disclosure. 2024A-CI0583-EP 21 -Oct-25

[0044] The terms used in the following embodiments are intended only to describe the purpose of a particular embodiment and are not intended to limit this disclosure. The terms “one”, “a” and “this” of singular forms used in this specification and the appended claims of this disclosure are also intended to include plural forms, unless otherwise specified in the context clearly. It should also be understood that in the following embodiments of this disclosure, “at least one” and “one or more” mean one or two or more. The term “and / or” describes an association relationship for describing associated objects and represents that three relationships may exist. For example, A and / or B may represent the following three cases: Only A exists, both A and B exist, and only B exists, where A and B may be singular or plural. The character “ / ” generally indicates an “or” relationship between the associated objects.

[0045] Reference to “one embodiment”, “some embodiments” or the like described in this specification means that one or more embodiments of this disclosure include a particular feature, structure, or characteristic described with reference to the embodiment. Therefore, the expressions “in one embodiment”, “in some embodiments”, “in some other embodiments” that appear in different parts of this specification do not necessarily mean reference to the same embodiment, but mean “one or more embodiments but not all embodiments”, unless otherwise specially emphasized. The terms “include”, “comprise”, “have”, and variations thereof mean “include, but are not limited to”, unless otherwise specifically emphasized.

[0046] There are numerous wires on the top of supermarkets, including sensor wires, camera wires, central emergency wires, DALI control wires, etc. Lamps may integrate functions such as emergency, induction, and DALI control, which requires more wire interfaces for the lamps.

[0047] An electrical track is a track system for installing and fixing lamps and other electrical equipment, with multiple wires arranged inside for power supply and control. A wire slot is a groove or channel inside the electrical track for accommodating and fixing wires, and each wire in the electrical track is arranged in an independent wire slot. As lamps have more functions, more wires are needed, resulting in more wires and wire slots arranged in the electrical track. On the basis that the width of the electrical track remains unchanged, the more the number of wire slots, the smaller their width will be. Current power plugs are usually arranged at intervals along the width direction, and the power-taking pieces on the power plugs have a certain width. When the width of the wire slots is limited and the distance between two adjacent wire slots is small, the power-taking pieces of two adjacent power plugs are prone to contact, posing a risk of short circuit. Moreover, it is difficult to arrange a large number of them when the track width is limited. 2024A-CI0583-EP 21 -Oct-25

[0048] Given that lamps have more and more functions, the applicant has developed electrical tracks with compactly arranged wire slots. Due to the limited width of the wire slots, it is necessary to design a relatively large number of connection terminals within a certain size. Each terminal should occupy a small space and meet requirements such as safety regulation compliance, suitability for automated production, and as low cost as possible.

[0049] Based on this, the present disclosure provides a power plug structure. The plug assemblies in different rows are arranged in a staggered manner in the width direction, which can reduce interference between adjacent plug assemblies. Even if the width of the wire slot of the electrical track is small, it can still ensure that each plug assembly maintains good contact with the conductive structure of the electrical track, making it suitable for use in limited spaces.

[0050] In addition, the present disclosure installs a relatively large number of connection terminals on the circuit board, which can meet the installation requirements of a relatively large number of connection terminals.

[0051] Furthermore, when the distance between the power-taking pieces on traditional power plugs is so small that it is easy to cause short circuits or arc discharges between adjacent power-taking pieces, affecting the stability of electrical connections. Moreover, the power-taking pieces have insufficient elasticity, and after long-term use, poor contact is likely to occur between the power-taking pieces and the conductive structure of the electrical track, affecting the stability of electrical connections.

[0052] In the case of small wire slot spacing, electrical safety must be ensured, and the power-taking structure must keep a reasonable interval. On the premise of small wire slot size, the power plug structure must also provide stable connections. Based on this, the present disclosure uses power-taking springs for power taking. On one hand, the power-taking springs can adapt to compactly arranged wire slots, and a relatively large distance can be maintained between the power-taking springs, which can effectively avoid short circuits between two adjacent socket assemblies. On the other hand, the power-taking springs have good resilience. When the power plug structure is inserted into the electrical track, the power-taking springs can closely contact the conductive structure in the electrical track, ensuring the stability of conduction. After long-term use, the power-taking springs can still maintain stable connections with the circuit board assembly and the conductive structure. 2024A-CI0583-EP 21 -Oct-25

[0053] The power plug structure of the first aspect of the present disclosure and the power-taking system of the second aspect of the present disclosure will be described in detail, in conjunction with Figures 1 to 9.

[0054] According to an embodiment of the present disclosure, in the first aspect, a power plug structure is provided. As shown in Figures 1 to 7, it comprises a plug housing, a circuit board assembly, and plug assemblies. The circuit board assembly is disposed in the plug housing and is used to provide a wire interface 16. The plug assemblies are arranged in multiple rows at intervals along the length direction; each row of plug assemblies comprises at least one plug assembly, and the plug assemblies between different rows are arranged in a staggered manner in the width direction. One end of each plug assembly is electrically connected to the circuit board assembly, and the other end of each plug assembly is electrically connected to the conductive structure 72 in the wire slot 71 of the electrical track 7.

[0055] In this embodiment, the plug assemblies between different rows are arranged in a staggered manner in the width direction, which can reduce interference between adjacent plug assemblies. Even if the width of the wire slot 71 of the electrical track 7 is small, it can still ensure that each plug assembly maintains good contact with the conductive structure 72 of the electrical track 7. The staggered arrangement of the multiple rows of plug assemblies makes full use of the space of the plug housing, resulting in a more compact overall structure. It is suitable for use in limited spaces and enables arrangement of a large number of plug assemblies. Additionally, the plug assemblies arranged in a staggered manner can reduce the risk of short circuits between adjacent plug assemblies, ensuring the safe operation of the electrical system.

[0056] The design of multiple rows of plug assemblies in this embodiment can adapt to different types of electrical tracks and conductive structures, and is applicable to a variety of application scenarios. The number and arrangement of plug assemblies can be selected according to actual needs to meet the requirements of different electrical equipment.

[0057] In some embodiments, the plug assemblies in different rows are arranged in a staggered manner in the height direction. This staggered arrangement design in the height direction allows for more rational use of the space of the plug housing, ensuring that each plug assembly has sufficient space for installation and connection without excessive compression in the width direction. Moreover, even if the width of the wire slots is limited, the plug 2024A-CI0583-EP 21 -Oct-25 assemblies can be staggered in the height direction to avoid mutual interference in the width direction, thereby enabling each plug assembly to be smoothly inserted into the wire slots.

[0058] Correspondingly, the wire slots and conductive structures 72 in different rows are also arranged in a staggered manner in the height direction. This further allows the plug assemblies in different rows to abut against the conductive structures 72 at different height positions, effectively reducing the risk of short circuits between plug assemblies in adjacent rows and ensuring the safe operation of the electrical system.

[0059] In some embodiments, as shown in Figure 2, the circuit board assembly comprises a circuit board 4 and connection terminals 5. A plurality of rows of contact conductive regions 41 are disposed on the circuit board 4, and each contact conductive region 41 is adapted to be electrically connected to one plug assembly respectively. The contact conductive regions 41 are used to ensure that the power-taking springs can take power from the circuit board during the rebound process.

[0060] A plurality of connection terminals 5 are provided, and each connection terminal 5 is disposed on the circuit board 4 and electrically connected to one contact conductive region 41 respectively. More specifically, the connection terminals 5 are electrically connected to the contact conductive regions 41 through circuits arranged along the length direction. The connection terminals 5 are exposed from the side of the plug housing.

[0061] In this embodiment, the design of multiple rows of contact conductive regions 41 makes full use of the space on the circuit board 4, resulting in a more compact overall circuit board assembly that is suitable for use in limited spaces. Each connection terminal 5 can be electrically connected to one plug assembly through one contact conductive region 41, thereby accomplishing the electrical connection between the connection terminal 5 and the conductive structure 72 of one wire slot.

[0062] In some embodiments, each connection terminal 5 is disposed on the circuit board 4 in a manner extending along the length direction. The plug housing is provided with a plurality of rows of sockets 17, and the rows of sockets 17 are arranged in a staggered manner in the width direction. The sockets 17 are arranged corresponding to the connection terminals 5; the sockets 17 are used to provide an accommodating space for the clamping assembly that limits the position of the connection terminals 5, ensuring the fixation of the connection terminals 5 in the plug housing, enhancing mechanical stability, and reducing poor electrical connections 2024A-CI0583-EP 21 -Oct-25 caused by loosening of the connection terminals 5. For example, the sockets 17 may be configured in form of snap grooves to prevent the connection terminals from falling out.

[0063] In some embodiments, the plug housing comprises a plug main body 1 and a plug cover plate 6 that are detachably connected to each other, facilitating the assembly and maintenance of the plug assemblies. Users can easily open the plug cover plate 6 to inspect, replace, or repair internal components. Both the plug main body 1 and the plug cover plate 6 are made of insulating material to provide insulation; more specifically, they are both made of plastic. The plug cover plate 6 serves to support the circuit board when the compressive force is transmitted to the circuit board during power taking by the power-taking spring 3.

[0064] As shown in Figure 3, one side of the plug main body 1 comprises a side opening. A plurality of partition plates 14 extending to the side opening are disposed on the plug main body 1. An accommodating groove 15 for receiving the connection terminals 5 is formed between two adjacent partition plates 14, which ensures the fixation of the connection terminals 5 in the plug housing and reduces poor electrical connections caused by loosening. A wire interface 16 is formed between the accommodating groove 15 and the circuit board 4; after inserting a wire into the wire interface 16, the wire can be electrically connected to the connection terminal 5. The design of the accommodating groove 15 and the wire interface 16 makes the connection between the connection terminals 5 and the circuit board 4 more organized and the layout more reasonable.

[0065] An insert plate 141 is further disposed at the bottom end of each partition plate 14. A plurality of jacks 61 are disposed at the top end of the side wall of the plug cover plate 6. Each insert plate 141 corresponds to a jack 61 in position; inserting the insert plate 141 into the jack 61 enables the alignment of the plug main body 1 and the plug cover plate 6.

[0066] A plurality of support ribs 62 are further disposed on the plug cover plate 6 to enhance the connection strength.

[0067] In some embodiments, the plug assembly comprises a plug 2 and a power-taking spring 3. The plug 2 is disposed on the plug housing, and the power-taking spring 3 is disposed inside the plug 2. One end of the power-taking spring 3 is adapted to be electrically abutted against the circuit board assembly, and the other end of the power-taking spring 3 extends out of the plug 2 and is adapted to be electrically abutted against the conductive structure 72 in the wire slot 71 of the electrical track 7. 2024A-CI0583-EP 21 -Oct-25

[0068] In this embodiment, the power-taking spring 3 can be a flexible conductive wire / column / rod. The design of the power-taking spring 3 ensures that it maintains good electrical connection between the circuit board assembly and the conductive structure 72 in the wire slot 71 of the electrical track 7. The elastic property of the power-taking spring 3 ensures that the contact points are always in close contact, reducing the risk of poor contact. The power-taking spring 3 occupies a small volume; even if the width of the wire slot 71 is small, the power-taking spring 3 can still effectively abut against the conductive structure 72 in the wire slot 71, making it suitable for use in limited spaces.

[0069] It should be noted that if conductive sheets are only replaced with conductive wires in traditional way, the conductive wires are easily deformed by external forces, leading to poor contact between the wires and the circuit board assembly as well as the conductive structure 72. The power-taking spring 3 in this embodiment is formed into a specific elastic structure and has good resilience, thereby ensuring reliable power taking. The power-taking spring 3 is made of copper alloy, which has high strength. After installation, the power-taking spring 3 can maintain long-term conductive contact with the conductive structure 72 and the circuit board assembly by virtue of its own elasticity and strength, ensuring stable operation.

[0070] The power-taking spring serves as both a conductor and a spring. Since the power-taking spring 3 is a copper alloy rod with high strength, it can be very small in volume. It can be made into a multi-position terminal within a certain volume, making it suitable for scenarios with strict requirements on structural volume, and its manufacturing process is simple.

[0071] The power-taking spring is suitable for low voltage power-taking tracks and can also be used for high voltage power-taking tracks. When the power-taking spring is applied to a high voltage power-taking track, its diameter can be increased to a certain extent to adapt to high current intensity.

[0072] In some embodiments, as shown in Figures 3, 5, and 6, a long slot 23 is penetratingly opened inside the plug 2. An abutting plate 24 is disposed in the long slot 23, and the abutting plate 24 divides the long slot 23 into an abutting groove 27 and a through hole 25. The abutting groove 27 is located at the end of the plug 2 away from the electrical track 7, and the through hole 25 penetrates the plug 2.

[0073] In this embodiment, the design of the abutting plate 24 provides a fixed support point, making the power-taking spring 3 more stable inside the plug 2 and reducing the risk of loosening. 2024A-CI0583-EP 21 -Oct-25

[0074] In some embodiments, as shown in Figure 4, the power-taking spring 3 comprises a first conductive part 31, an abutting part 32, and a second conductive part 33 connected in sequence. The power-taking spring 3 is formed by bending a single conductive wire. The first conductive part 31 is electrically abutted against the circuit board assembly; the abutting part 32 is disposed in the abutting groove 27 and adapted to engage the abutting plate 24; the second conductive part 33 is disposed in the through hole 25 and extends out of the through hole 25, and is electrically abutted against the conductive structure 72 in the wire slot 71 of the electrical track 7.

[0075] In this embodiment, the abutting part 32 is disposed in the abutting groove 27 and adapted to engage the abutting plate 24, which ensures the fixed position of the power-taking spring 3 inside the plug 2 and reduces poor contact caused by vibration or movement. The segmented design of the first conductive part 31, the abutting part 32, and the second conductive part 33 allows each part to better adapt to different regions inside the plug 2.

[0076] When the plug is inserted into the wire slot, the electrical abutment between the first conductive part 31 and the circuit board assembly, and the electrical abutment 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, improving the plugging speed and efficiency.

[0077] More specifically, as shown in Figures 5 and 8, the first conductive part 31 is configured in a hook shape with the opening facing away from the circuit board assembly. The second conductive part 33 is configured in a hook shape with the opening facing away from the conductive structure 72; specifically, the second conductive part 33 is U-shaped, and the U- shaped opening of the second conductive part 33 gradually expands from the side close to the conductive structure to the side far away from the conductive structure. The abutting part 32 comprises a first conductive arc segment 321 and a second conductive arc segment 322 connected to each other; the first conductive arc segment 321 is connected to the first conductive part 31, and the second conductive arc segment 322 is connected to the second conductive part 33. Correspondingly, a part of the abutting plate 24 is also configured in two arc shapes; the abutting plate 24 comprises a first curved segment 241 and a second curved segment 242. The openings of the first conductive arc segment 321 and the first curved segment 241 face the circuit board assembly, and the openings of the second conductive arc segment 322 and the second curved segment 242 face away from the circuit board assembly. 2024A-CI0583-EP 21 -Oct-25

[0078] After the power-taking spring 3 is installed in place, the first curved segment 241 of the abutting plate 24 can always exert a pressing force on the first conductive part 31 toward the circuit board assembly, ensuring that the first conductive part 31 is always in close contact with the circuit board assembly. When the power plug structure is installed on the electrical track 7, the conductive structure on the electrical track 7 exerts a downward pressing force on the second conductive part 33, causing the second conductive part 33 to move downward. After the second conductive part 33 moves downward, due to the elastic effect of the powertaking spring 3, the second conductive part 33 of the power-taking spring 3 generates an upward tendency to move, thereby enabling close contact with the conductive structure on the electrical track 7 and ensuring the stability and reliability of power taking.

[0079] In some embodiments, the abutting groove 27 and the through hole 25 in the plug 2 are opened along the length direction, and their width is slightly larger than the outer diameter of the power-taking spring 3 (specifically referring to the outer diameter of the cross-sectional circle of the power-taking spring 3). The first conductive part 31, the abutting part 32, and the second conductive part 33 of the power-taking spring 3 are also arranged along the length direction. In the above technical solution, the overall width of the power-taking spring 3 after being positioned in the plug 2 is small, which is very suitable for scenarios where the width of the wire slot on the electrical track is small.

[0080] In some embodiments, as shown in Figure 6, the plug 2 comprises a plug-in part 21 and a fixing part 22. The fixing part 22 is positioned on the plug housing, and the plug-in part 21 is connected to the fixing part 22 and inserted into the wire slot 71 of the electrical track 7. The width of the plug-in part 21 gradually decreases from the side far away from the electrical track 7 to the side close to the electrical track 7.

[0081] In this embodiment, the width of the plug-in part 21 gradually decreases from the side far away from the electrical track 7 to the side close to the electrical track 7, forming a wedge shaped structure. This allows the plug 2 to be inserted into the wire slot 71 of the electrical track 7 more smoothly, reducing resistance and jamming during insertion. The gradually changing width design enables the plug 2 to adapt to wire slots of different widths, especially those with small widths, thus improving the application range of the plug 2.

[0082] In some embodiments, at least one plug assembly is arranged in a movable form, and the plug assembly can switch the circuit of the circuit board assembly when moving. 2024A-CI0583-EP 21 -Oct-25

[0083] In this embodiment, the mobility of the plug assembly allows users to dynamically adjust the position of the plug according to actual needs, thereby realizing flexible switching of the circuit board assembly circuit. This enables the device to adapt to different usage scenarios and requirements, improving the adaptability and flexibility of the system. By moving the plug assembly, users can conveniently switch different circuit functions, allowing a single device to realize multiple functions.

[0084] More specifically, the plug housing is provided with a sliding opening 13 and a slide rail 11. The plug 2 is slidably disposed on the slide rail 11, and the power-taking spring 3 passes through the sliding opening 13. The circuit board assembly directly below the sliding opening 13 has multiple contact positions. When the plug 2 slides to different positions along the slide rail 11, the power-taking spring 3 is electrically connected to different contact positions of the circuit board assembly.

[0085] In this embodiment, users can move the plug 2 along the slide rail 11, which makes the power-taking spring 3 slide in the sliding opening 13, realizing the switching of different contact positions of the circuit board assembly. Users can switch circuits by simply sliding the plug 2, which is easy to operate, improves user experience, and achieves high switching efficiency.

[0086] As shown in Figure 3, the side wall of the slide rail 11 is provided with a plurality of grooves 12. As shown in Figure 7, the plug 2 is provided with a protrusion 26 adapted to match the grooves 12. When the plug 2 slides along the slide rail 11 to the positions of different grooves 12, the plug 2 is positioned, and the power-taking spring 3 is electrically connected to different contact positions of the circuit board assembly.

[0087] In this embodiment, the protrusion 26 on the plug 2 is adapted to the grooves 12 on the side wall of the slide rail 11, ensuring that the plug 2 can achieve precise alignment when sliding to a specific position, and avoiding incorrect circuit connection caused by positional deviation. The cooperation between the protrusion 26 and the grooves 12 can also ensure that the plug 2 is stably fixed when moving to the position of the grooves, reducing shaking or displacement of the plug 2 during use.

[0088] In some embodiments, the plug housing is further provided with an anti-reverse rib 8, which is disposed at a non-central position of the plug housing; specifically, the anti-reverse rib 8 can be disposed between the gaps of two adjacent plug assemblies. In this embodiment, the provision of the anti-reverse rib 8 ensures that the power plug structure has only one correct 2024A-CI0583-EP 21 -Oct-25 installation orientation, preventing the entire power plug structure from being installed in the reverse direction.

[0089] The above power plug structure is suitable for both low voltage and high voltage powertaking tracks. It uses the elasticity and conductivity of the power-taking spring 3 itself to be assembled into the electrical track. The power-taking spring 3 abuts against the conductive sheets / wires in the track, and its bottom contacts the circuit board, which can maintain conductive stability for a long time. Due to its small volume, it is particularly suitable for multi-position wire slots and can provide more connections in the width direction.

[0090] According to an embodiment of the present disclosure, in the second aspect, a power-taking system is provided, as shown in Figure 9, which comprises an electrical track 7 and a power plug structure, and the power plug structure is connected to the electrical track 7. The electrical track 7 is provided with a plurality of wire slots 71, and a conductive structure 72 is disposed in each wire slot 71. The conductive structure 72 is a conductive wire or a conductive sheet; preferably, the conductive structure 72 is a copper strip, and the powertaking spring 3 on the power plug structure is an elastic copper wire.

[0091] In some embodiments, a plurality of wire slots 71 are arranged at intervals along the length direction, and two adjacent wire slots 71 are arranged in a staggered manner in the height direction.

[0092] In this embodiment, through the staggered arrangement, more wire slots 71 can be arranged within the same horizontal area, improving space utilization. The staggered arrangement of the wire slots 71 in the height direction can make full use of vertical space, making the internal layout of the device more compact and saving horizontal space.

[0093] The above are only preferred embodiments of the present disclosure, and are not intended to limit the protection scope of the present disclosure. Any modifications, equivalent replacements or improvements within the spirit of the present disclosure are included within the scope of the claims of the present disclosure. 2024A-CI0583-EP 21 -Oct-25
