Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to a connector for connecting magnetic conductive tracks, a magnetic conductive track system, and a lighting device. Background Technology

[0002] Track lights mainly consist of a track (conductive track) fixed to the ceiling or wall and various light bodies that can slide along the track, such as spotlights and linear lights.

[0003] like Figure 1 As shown, Figure 1 This is a schematic diagram of a low-voltage guide rail using top-mounted power supply in the prior art. The guide rail 91 includes a main body 911, whose cross-section is approximately flat along the width of the guide rail 91. Two recessed receiving grooves 912 are recessed on the upper surface of the main body 911, parallel to the length of the guide rail 91. Each receiving groove 912 contains a coupling element 913, which is insulated from the main body 911. Each coupling element 913 includes a snap-fit ​​member 9131, within which a conductive sheet 9132 is snapped. The upper surface of the snap-fit ​​member 9131 has a mating space 9133 that exposes the conductive sheet 9132, thus enabling top-mounted electrical power supply. Between the two receiving grooves 912, the main body 911 has a receiving cavity 914 along the length of the guide rail 91, within which a magnetic suction member 915 is snapped. Both the conductive sheet 9132 and the magnetic component 915 are arranged horizontally and in a left-center-right arrangement; the lamp and the guide rail 91 are connected in a face-to-face manner, the conductive part of the lamp extends into the docking space 9133 and docks with the conductive sheet 9132, while the magnetic part of the lamp is arranged face-to-face with the upper surface of the main body 911.

[0004] like Figure 2 As shown, Figure 2This is a schematic diagram of a low-voltage guide rail that uses the inner sidewall of the guide rail for power extraction in the prior art. The guide rail 92 includes a main body 921, and the cross-section of the main body 921 is generally inverted U-shaped along the width direction of the guide rail 92. A magnetic suction component 922 is clamped on the inner top surface of the main body 921. Similarly, since the magnetic suction component 922 is located at the top of the guide rail 92, it cannot directly contact the lamp body, so the attraction force is relatively weak. Receiving grooves 923 are respectively provided on the left and right inner sidewalls of the main body 92. The receiving grooves 923 are arranged parallel to the length direction of the guide rail 92. A coupling element 924 is placed in each receiving groove 923. The coupling element 924 is insulated from the main body 92. Each coupling element 924 includes a snap-fit ​​component 9241, and a conductive component 9242 is clamped in the snap-fit ​​component 9241. The conductive component 9242 is exposed on the left and right inner sidewalls of the main body 92, thereby realizing the power extraction method from the inner sidewall of the guide rail 92. The coupling element 924 and the magnetic component 922 are distributed in the same space, arranged vertically with a height difference. The magnetic component 922 is located at the top inside the space, and the conductive component 9242 is circular. This determines the way the lamp is connected by filling the space.

[0005] Currently, most magnetic track lights on the market use plug-in or snap-fit ​​screws to connect the track to the other rail, which is inconvenient to disassemble and requires tools. Furthermore, there are currently no suitable connectors for magnetic track lights. Even if connectors are used, their structure is similar to plugs. Plugs use conductive terminals to connect to the conductive strip in the track, but the mechanical structure of plugs lacks reliability, the electrical connection between the conductive terminals and the conductive strip is affected, and magnets cannot attract them, failing to meet the same fixing requirements as magnetic track lights.

[0074] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0075] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0076] like Figures 3 to 5As shown in the figure, this application discloses a magnetically attracted conductive track 100, which is a long, flat strip and is used to be assembled on a mounting base and to form a magnetic attraction and electrical connection with a lighting device (not shown). The magnetic conductive track 100 includes a mounting body 10, a pair of coupling elements 20, and a magnetic element 30. The mounting body 10 extends along its length and is flat, including a mounting wall 11, a first guide rail wall 12, a second guide rail wall 13, and a receiving space 101. The first guide rail wall 12 and the second guide rail wall 13 are connected to the lower surface of the mounting wall 11 and are spaced apart. The receiving space 101 is enclosed by the mounting wall 11, the first guide rail wall 12, and the second guide rail wall 13. Conductive grooves 102 are formed on the outer surfaces of the first guide rail wall 12 and the second guide rail wall 13, and slots 103 are formed on the first guide rail wall 12 and the second guide rail wall 13. The slots 103 are located at the bottom of the receiving space 101. The coupling elements 20 are disposed in the conductive grooves 102 on the outer surfaces of the first guide rail wall 12 and the second guide rail wall 13. The magnetic element 30 is disposed in the slots 103 and closes the bottom of the receiving space 101.

[0077] In this embodiment, the first guide rail wall 12 and the second guide rail wall 13 are parallel to each other, so the cross-section of the mounting body 10 along the width direction is inverted U-shaped. The inverted U-shaped structure of the mounting body 10 forms the receiving space 101. At the bottom of the receiving space 101, the magnetic element 30 is engaged in the slot 103.

[0078] In other embodiments, the first guide rail wall 12 and the second guide rail wall 13 can also be configured to be non-parallel, for example, the first guide rail wall 12 and the second guide rail wall 13 can be configured in a figure-eight shape, which can also provide the same structure and function as described above. Preferably, the mounting wall 11 is arranged in a horizontal direction, the first guide rail wall 12 and the second guide rail wall 13 are both perpendicularly connected to the mounting wall 11, the first guide rail wall 12 and the second guide rail wall 13 are both arranged in a vertical direction, the conductive groove 102 is arranged in a vertical direction, the coupling element 20 installed in the conductive groove 102 is arranged in a vertical direction, the slot 103 is arranged in a horizontal direction, and the magnetic element 30 is arranged in a horizontal direction.

[0079] In one embodiment, the mounting wall 11 has at least two elliptical mounting holes 111 near its two ends, the number of which is determined according to the length of the magnetic conductive track 100. The mounting holes 111 are for screws to pass through, and the screw heads eventually press against both sides of the mounting holes 111 of the mounting wall 11 and lock with the mounting base (ceiling or wall) to fix the magnetic conductive track 100 to the mounting base.

[0080] In this embodiment, each coupling element 20 includes an insulating portion 21 and a conductive portion 22. The insulating portion 21 is housed within the conductive groove 102 and has a first space 215 and a second space 216 that communicate with each other. The first space 215 is close to the bottom of the conductive groove 102, and the second space 216 is away from the bottom of the conductive groove 102 and faces outward. The conductive portion 22 is housed within the first space 215 and exposed in the second space 216, for power supply to the lighting device. That is, the conductive portion 22 is housed within the first space 215 of the insulating portion 21, and a portion of the structure of the conductive portion 22 is exposed at the corresponding second space 216, allowing the conductor of the lamp body to enter the second space 216 and thus electrically connect with the conductive portion 22. The insulating portion 21, housed within the conductive groove 102, provides reliable insulation. The conductive parts 22 are arranged in pairs and are flat strips, serving as positive and negative electrodes respectively. They are located on both sides of the magnetic conductive track 100 and form an electrical connection with the conductive terminals of the lamp body that is adsorbed and assembled on the magnetic conductive track 100, thereby illuminating the lamp body. The conductive parts 22 are conductive copper foil or copper strips. The insulating part 21 may be omitted when the mounting body 10 is made of insulating material.

[0081] The insulating portion 21 is housed within the conductive groove 102 and generally has a U-shaped structure. Specifically, it includes a bottom wall 211 parallel to the bottom of the conductive groove 102, a first insulating sidewall 212 extending vertically from the bottom wall, and a second insulating sidewall 213 extending from the first insulating sidewall 212 and parallel to the bottom wall. The distance between the second insulating sidewalls 213 is less than the distance between the first insulating sidewalls 212. Therefore, the bottom wall and the first insulating sidewalls 212 enclose the first space 215, and the conductive portion 22 is attached to the bottom wall 211 and located between the first insulating sidewalls 212. The second insulating sidewalls 213 enclose the second space 216. The first insulating sidewalls 212 are located between the sidewalls of the conductive groove 102 and form surface-to-surface contact. The optimal design is that the first insulating sidewalls 212 and the conductive groove 102 form an interference fit.

[0082] like Figure 4 , Figure 6 , Figure 7 As shown in the embodiment of this application, a socket 110 is formed at each end of the mounting body 10 along the length direction, and the socket 110 is connected to the receiving space 101.

[0083] like Figure 4 , Figure 6 , Figure 7 As shown in the embodiment of this application, the magnetic conductive track 100 further includes an electrical plug 200; the electrical plug 200 can be inserted into one of the sockets 110, and the electrical plug 200 and the conductive part 22 form an electrical connection at the second space 216.

When the plug 200 is inserted into the socket 110, the conductive spring 204 forms an electrical connection with the end of the conductive part 22.

[0085] In this embodiment of the application, the electrical plug 200 further includes an extension 201, a head 202, and a snap-fit ​​portion 203.

[0086] The extension 201 is housed within the socket 110.

[0087] The head 202 is sealed outside the socket 110 and is flush with the outermost edge of the mounting body 10; the head 202 is connected to the extension 201, and the width and height of the head 202 are equal to the width and height of the mounting body 10, while the width and height of the extension 201 are both smaller than the width and height of the head 202.

[0088] The latching portions 203 are formed in pairs on the extension portion 201 and / or the head portion 202. That is, the latching portions 203 can be provided on the extension portion 201 or on the head portion 202. Of course, the latching portions 203 are provided on both the extension portion 201 and the head portion 202.

[0090] More specifically, in the embodiments of this application, the latching portion 203 includes a pair of outer latching walls 2031 and a pair of wedge-shaped guide portions 2032; the outer latching walls 2031 are symmetrically disposed on the head 202 and extend parallel to the extension portion 201, that is, the outer latching walls 2031 are vertically connected to the edge of the side surface of the head 202 facing the extension portion 201, and are disposed parallel to the extension portion 201; wherein the outer latching walls 2031 are preferably elastically connected to the head 202, and the outer latching walls 2031 are flush with the edge of the head 202. The wedge-shaped guide portions 2032 are symmetrically arranged on the two opposite outer sidewalls of the extension portion 201, that is, the outer surface of the wedge-shaped guide portions 2032 facing the outer sidewall 2031, so that the first guide rail wall 12 and the second guide rail wall 13 can be engaged between the corresponding outer sidewall 2031 and the wedge-shaped guide portions 2032; wherein, the conductive spring piece 204 is located between the outer sidewall 2031 and the extension portion 201 and is arranged corresponding to the conductive groove 102; when the extension portion 201 is accommodated in the insertion hole 110, the pair of outer sidewalls 2031 abut against the outer surfaces of the first guide rail wall 12 and the second guide rail wall 13 respectively, the pair of wedge-shaped guide portions 2032 abut against the inner surfaces of the first guide rail wall 12 and the second guide rail wall 13 respectively, and the conductive spring piece 204 extends into the corresponding conductive groove 102 and abuts against the outer surface of the end of the conductive portion 22 to be electrically connected to the coupling element 20.

[0091] In this embodiment of the application, the head 202 further includes a pair of grooves 2021 corresponding to the first guide rail wall 12 and the second guide rail wall 13. The grooves 2021 face the corresponding first guide rail wall 12 and the second guide rail wall 13. The conductive spring 204 is generally U-shaped, and the conductive spring 204 is locked in each groove 2021.

[0092] In this embodiment, the conductive spring 204 includes a first conductive segment 2041, a second conductive segment 2042, and a third conductive segment 2043 connected in sequence.

The elastic contact portion is an arc-shaped elastic contact portion, which not only provides the function of electrical contact but also provides a guiding function during electrical connection.

[0093] In this embodiment of the application, the extension 201 is further provided with a positioning block 2011. The edge of the positioning block 2011 is flush with the edge of the groove 2021. A gap is provided between the positioning block 2011 and the inner wall of the extension 201. The width of the gap is equal to the thickness of the first conductive segment 2041.

[0095] In this embodiment, the electrical plug 200 includes an upper housing 210 and a lower housing 220; the upper housing 210 and the lower housing 220 have basically the same structure. Specifically, the upper housing 210 has an upper head, an upper extension, and an upper latching portion; the lower housing 220 is assembled with the upper housing 210, and the lower housing 220 has a lower head, a lower extension, and a lower latching portion corresponding to the upper head, the upper extension, and the upper latching portion, respectively; wherein the upper head and the lower head form the head 202, the upper extension and the lower extension form the extension 201, and the upper latching portion and the lower latching portion form the latching portion 203; a pair of conductive spring contacts 204 are sandwiched between the upper housing 210 and the lower housing 220.

[0096] The electrical plug 200 is located at the first section of the end of the magnetic conductive track 100. Its purpose is to electrically connect to an external power source for power supply. The remaining cascaded magnetic conductive tracks 100 all achieve electrical transmission through connectors 500. When the driving power supply is external, the two conductive contacts 204 of the electrical plug 200 are electrically connected to the positive and negative terminals, respectively.

[0097] like Figure 4 , Figure 8 , Figure 9 As shown in this embodiment, the magnetic conductive track 100 further includes a sealing plug 300, which can be inserted into another socket 110 to seal the receiving space 101. In this embodiment, the shape of the sealing plug 300 is kept as consistent as possible with that of the electrical plug 200.

[0098] In this embodiment, the sealing plug 300 includes an insertion portion 301, a sealing head 302, and a locking portion 303. The insertion portion 301 is accommodated within the socket 110. The sealing head 302 seals the outside of the socket 110 and is flush with the outermost edge of the mounting body 10. The sealing head 302 is connected to the insertion portion 301, and the width and height of the sealing head 302 are equal to the width and height of the mounting body 10, while the width and height of the insertion portion 301 are less than the width and height of the sealing head 302. The locking portion 303 is disposed on the insertion portion 301 and / or the sealing head 302. When the insertion portion 301 is accommodated within the socket 110, the locking portion 303 is used to engage with the inner surfaces of the first guide rail wall 12 and the second guide rail wall 13 to fix the sealing plug 300 to the mounting body 10.

[0099] In this embodiment, the locking part 303 is a wedge-shaped block, which facilitates the insertion of the sealing plug 300 into and locking it in the socket 110.

[0100] In detail, in this embodiment of the application, the first guide rail wall 12 is provided with a third inner groove 122 at the position corresponding to the locking part 303. When the insertion part 301 is accommodated in the insertion hole 110, the locking part 303 is engaged in the third inner groove 122. The second guide rail wall 13 is provided with a fourth inner groove 132 at the position corresponding to the locking part 303. When the insertion part 301 is accommodated in the insertion hole 110, the locking part 303 is engaged in the fourth inner groove 132. This structure prevents the insertion part 301 from falling out of the insertion hole 110.

[0101] like Figure 4 , Figure 5 As shown in this embodiment, the magnetic conductive track 100 further includes a driving power supply 40, housed within the receiving space 101, and electrically connected to the coupling element 20. The extension direction of the driving power supply 40 is the same as the length extension direction of the magnetic conductive track 100. The driving power supply 40 may include various circuit modules, a control module, a Bluetooth module, or a Wi-Fi module (the control module may integrate a Bluetooth module or a Wi-Fi module). When the driving power supply is built-in, the driving power supply 40 is electrically connected to the coupling element 20 for power supply. In this case, the electrical plug 200 is not required; only the sealing plug 300 needs to be provided at the end of the magnetic conductive track 100.

[0102] Please refer to Figure 10A , 10B , Figure 11 In conjunction with the above embodiments, this application also provides a lighting device 1, which includes the magnetic conductive track 100 as described above.

[0103] Please refer to Figure 10A , 10B , Figure 11The lighting device 1 further includes a lighting device 400, which can form a magnetic attraction and electrical connection with the magnetic conductive track 100. In a specific implementation, the lighting device 400 includes a base 401, a wire 402, and a lamp body 403. The base 401 is U-shaped, with an assembly cavity 410 at its top. The assembly cavity 410 is positioned opposite to the magnetic conductive track 100, and completely covers the magnetic conductive track 100. The assembly cavity 410 has an electrical connection side 411 and a magnetic adsorption side 412. The electrical connection side 411 is provided with an elastic electrical contact 404, which extends into the conductive groove 102 and is electrically connected to the coupling element 20. The magnetic adsorption side 412 is provided with an adsorption element 405, which is engaged in the bottom groove of the assembly cavity 410 and corresponds to and adsorbs with the magnetic element 30 in the slot 103. The lower surface of the base 401 has a through hole. One end of the wire 402 is connected to the elastic electrical contact 404. The other end of the wire 402 passes through the through hole and is electrically connected to the lamp body 403.

[0104] Please refer to Figure 10A In one embodiment, the lighting device 400 further includes a connecting rod 406, a nut 407, and a washer 408. One end of the connecting rod 406 passes through the through hole and is fixed to the lower surface of the base 401 by the nut 407. The lamp body 403 is connected to the other end of the connecting rod 406. The washer 408 is disposed between the nut 407 and the lower surface of the base 401, and the outer diameter of the washer 408 is larger than the outer diameter of the through hole. The nut 407 is tightened to the connecting rod 406 to fix the connecting rod 406 to the through hole of the base 401. The washer 408 can increase the contact area and strengthen the fixation between the nut 407 and the connecting rod 406. Moreover, a through hole for the wire 402 to pass through is provided at the center of the connecting rod 406 and the nut 407, thereby realizing that the elastic electrical contact 404 is electrically connected to the lamp body 403 through the wire 402.

[0105] Please refer to Figure 10B In another embodiment, the base 401 and the lamp body 403 in the lighting device 400 are integrally formed, or the base 401 and the lamp body 403 are connected by an adapter to form an integral structure.

[0106] It is understood that the lighting device 400 is slidably disposed on the lower surface of the magnetic conductive track 100, and the lighting device 400 includes at least one of spotlights, wall washer lights, linear lights, panel lights, pendant lights, and power modules.

[0107] like Figures 12 to 21 As shown in the illustration, this application also discloses a connector 500a, 500b, 500c, or 500d for connecting a magnetic conductive track 100. The magnetic conductive track 100 and the connectors 500a, 500b, 500c, or 500d are connected to form a magnetic conductive track system. The magnetic conductive track 100, the connectors 500a, 500b, 500c, or 500d, and the lighting device 400 connected to the magnetic conductive track 100 together constitute a lighting device 1.

[0108] Please refer to the following at the same time Figure 1 , Figure 12 , Figure 15 , Figure 18 , Figure 20 The connectors 500a, 500b, 500c, and 500d of this application can be installed on the corresponding magnetic end caps 14, thereby enabling the flexible arrangement and connection of multiple magnetic conductive tracks 100. Furthermore, the connectors 500a, 500b, 500c, and 500d can also form an electrical connection with the conductive part 22 at the second space 216, thus achieving a dual transition between mechanical and electrical connections.

[0109] by Figure 17 For example, Figure 17 This is an enlarged view of the connector 500b and the magnetic conductive track 100 after assembly. The connector 500b includes a housing 51, which includes two transition sidewalls 52 and two pairs of conductive terminals 54. The two transition sidewalls 52 are parallel to each other and are located on opposite sides of the housing 51, used to connect the two magnetic conductive tracks 100 in a straight line. The two pairs of conductive terminals 54 protrude from the corresponding transition sidewalls 52, and each conductive terminal 54 has an electrical connection portion 5542 at the protrusion position of the transition sidewall 52. The housing 51 is in a straight line shape, so that the magnetic conductive tracks 100 located on both sides of the connector 500b are electrically connected through the conductive terminals 54.

[0110] In summary, the connectors 500a, 500b, 500c, and 500d include a housing 51, which has at least two transition sidewalls 52. Each transition sidewall 52 can connect to a magnetic conductive track 100, and each transition sidewall 52 is provided with a magnetic surface 531, which can be attracted to the end of the corresponding magnetic conductive track 100. In other words, the magnetic surface 531 can be attracted to the magnetic end cap 14 of the corresponding magnetic conductive track 100. The connectors 500a, 500b, 500c, and 500d further include at least two pairs of conductive terminals 54, which are respectively distributed on both sides of the corresponding magnetic attraction surface 531. The conductive terminals 54 have a fixing part and an electrical docking part. The fixing part 5541 is disposed inside the housing 51, and the electrical docking part 5542 protrudes from the housing 51. The electrical docking part 24 can form an electrical connection with the conductive part 22 of the corresponding magnetic attraction conductive track 100.

[0111] Example 1

[0112] like Figure 12 , Figure 13 , Figure 14 As shown, in Embodiment 1, the connector 500a is configured with an H-type or cross-type structure, which can realize the H-type or cross-type connection of the magnetic conductive rails 100. The system composed of the connector 500a and four magnetic conductive rails 100 is a magnetic conductive rail system. The connector 500a realizes the mechanical and electrical connection with the magnetic conductive rails 100, and after cascading the magnetic conductive rails 100, it is flush with the ends of the magnetic conductive rails 100 and respectively attached to the surface of the mounting base.

[0113] Please see Figure 12 , Figure 13 The connector 500a includes a housing 51 and four pairs of conductive terminals 54 disposed within the housing 51 and partially protruding from the housing 51 to form an electrical connection with the conductive portion 22 at the end position of the magnetic conductive track 100. The housing 51 may be integrally formed with the conductive terminals 54, or it may include a first body 510 and a second body 520 assembled with the first body 510 along the height direction, with the conductive terminals 54 sandwiched between the first body 510 and the second body 520.

[0114] Please see Figure 12 , Figure 13 , Figure 14The connector 500a is preferably rectangular and has four sides. Each side of the housing 51 is provided with a pair of conductive terminals 54 to form a transition sidewall 52, that is, the four sides of the connector 500a form four transition sidewalls 52. The connector 500a with H-type or cross-type structure includes four transition sidewalls 52 for connecting two rows of magnetic conductive tracks 100 located perpendicular to each other, with two magnetic conductive tracks 100 in each row.

[0115] When the connector 500a mates with the conductive portion 22 at the end position of different magnetic conductive tracks 100, the electrical mating portion 5542 inserts into the conductive groove 102 to form an electrical connection with the conductive portion 22 at the end position. After assembly, the connector 500a remains flush with the upper and lower surfaces of the magnetic conductive track 100 and is fitted against the surface of the mounting base, resulting in a flat, simple, and low-height overall structure.

[0116] like Figure 13 As shown in the embodiment of this application, the conductive terminal 54 is a spring-loaded structure, including a first conductive segment 541, a second conductive segment 542, and a third conductive segment 543; the first conductive segment 541 and the third conductive segment 543 are arranged in parallel and are both perpendicularly connected to one end of the second conductive segment 542; wherein, a portion of the structure of the first conductive segment 541, the second conductive segment 542, and the third conductive segment 543 forms the fixing portion 5541, and the third conductive segment 543 extends away from the second conductive segment 542 to form a guide arc portion, which forms the electrical connection portion 5542.

[0117] like Figure 13 As shown, a positioning block 56 is provided inside the outer casing 51. The positioning block 56 has a groove 561 for engaging the conductive terminal 54. When the conductive terminal 54 is engaged in the groove 561, the edge of the conductive terminal 54 is flush with the edge of the groove 561, forming a face-to-face fit, preferably an interference fit. The fixing part 5541 is attached to the groove 561, and the electrical connection part 5542 extends outside the groove 561.

[0118] To address the issue of magnets failing to attract the connector 500a and to meet the same fixing requirements as the magnetic conductive track 100, four magnetic adsorption elements 53 are provided inside the connector 500a, each with a magnetic surface 531. Alternatively, in other embodiments, one magnetic adsorption element 53 with four magnetic surfaces 531 can be provided inside the connector 500a, and this element is housed within the outer casing 51. The preferred material for the magnetic adsorption element 53 is iron. Therefore, this application does not limit the number of magnetic adsorption elements 53; as long as each adapter sidewall 52 has a magnetic surface 531, it is sufficient.

[0119] like Figure 12 , Figure 13 As shown, a receiving opening is provided on the adapter sidewall 52, and the magnetic surface 531 of the magnetic adsorption element 53 is exposed to the outside from the receiving opening.

[0120] The magnetic adsorption element 53 is snapped into the outer casing 51, and four pairs of conductive terminals 54 are distributed on both sides of the magnetic adsorption surface 531. Specifically, the positioning block 56 has a snap-fit ​​protrusion 562 perpendicular to the first body 510 or the second body 520 on the side opposite to the conductive terminal 54 (or groove 561), so that there are two snap-fit ​​protrusions 562 oppositely arranged between the two positioning blocks 56, and the two snap-fit ​​protrusions 562 form a snap-fit ​​structure; the magnetic adsorption element 53 has an I-shaped cross-section in the width direction, and the magnetic adsorption element 53 has a slot 532 at the position corresponding to the snap-fit ​​protrusion 562. The magnetic adsorption element 53 is snapped into the snap-fit ​​protrusion 562 through the slot 532, thereby realizing that the magnetic adsorption element 53 is snapped between the two positioning blocks 56.

[0121] For ease of wiring, such as Figure 13 As shown, the second conductive segment 542 is also provided with a wire clamping structure. The wire clamping structure includes a square wire through hole 5421 located on the second conductive segment 542 and a pair of wire clamping tabs 5422. The pair of wire clamping tabs 5422 are respectively connected to opposite sides of the square wire through hole 5421 and are located on the same side of the second conductive segment 542. The pair of wire clamping tabs 5422 are curved spring tabs. In use, the conductive end of the wire passes through the square wire through hole 5421 and is clamped in the pair of wire clamping tabs 5422 to achieve electrical connection. That is, the conductive end of the wire is inserted between the curved spring tabs to form a V-clamping connection.

[0122] If the connector 500a connects the magnetic conductive track 100 in a cross shape, please refer to Figures 12 to 13. Figure 14As shown, connector 500a has a cross-shaped structure, including a quadrilateral housing 51 and a pair of transition sidewalls 52 extending from each side of the housing 51 and close to both ends. The conductive terminal 54 includes a quadrilateral fixing portion 5541 and four sets of electrical mating portions 5542 extending parallel from each side of the fixing portion 5541. The electrical mating portions 5542 protrude from their respective transition sidewalls 52 and are located between a pair of transition sidewalls 52 on the same side. The electrical mating portions 5542 are arranged in pairs, representing positive and negative terminals respectively. Therefore, connector 500a can form mechanical and electrical connections with the conductive portions 22 at the ends of the four magnetic conductive tracks 100, arranging the four magnetic conductive tracks 100 in a cross shape to form a cross-shaped magnetic conductive track system.

[0123] In summary, in the cross-shaped connector 500a, the housing 51 includes four vertically arranged transition sidewalls 52 and four pairs of conductive terminals 54. The four vertically arranged transition sidewalls 52 are used to connect the four magnetic conductive tracks 100. The four pairs of conductive terminals 54 protrude from the corresponding transition sidewalls 52.

[0124] To facilitate the insertion of the transition sidewall 52 of the outer casing 51 into the square insertion hole 110 at the end of the magnetic conductive track 100 and achieve a better visual effect, the outer casing 51 includes four vertically arranged protrusions 55, the end faces of which are configured as the transition sidewall 52. The protrusions 55 extend into the square insertion hole 110 to achieve a seamless connection.

[0125] Of course, the connector 500a can also be H-shaped as a whole. In this case, the outer shell 51 is H-shaped. The only difference between this and the cross-shaped connector 500a is the arrangement of the four vertically arranged adapter sidewalls 52.

[0126] Example 2

[0127] Embodiment 2 of this application includes most of the features of Embodiment 1, except that it is not the H-type or cross-type structure of the connector 500a described in Embodiment 1, but a line type (or I-type).

[0128] like Figure 15 , Figure 16As shown in Embodiment 2 of this application, if the magnetic conductive tracks 100 need to be connected in a straight line, the connector 500b is designed as a straight-line structure, including a quadrilateral outer shell 51 and parallel outer shells 51 extending from opposite sides of the outer shell 51. The connector 500b is a straight-line structure, and the widths of the outer shells 51 can be the same to achieve a smooth connection. The conductive terminal 54 includes a quadrilateral fixing portion 5541 and parallel electrical mating portions 5542 extending from opposite sides of the fixing portion 5541. Therefore, the connector 500b can form mechanical and electrical connections with the conductive portions 22 at the ends of the two magnetic conductive tracks 100, respectively, and arrange the two magnetic conductive tracks 100 in a straight line, forming a straight-line magnetic conductive track system.

[0129] In summary, in the connector 500b with a straight-line structure, the outer shell 51 includes the two transition sidewalls 52 and the two pairs of conductive terminals 54; the two transition sidewalls 52 are parallel to each other and are disposed on opposite sides of the outer shell 51 to connect the two magnetic conductive tracks 100 in a straight line; the two pairs of conductive terminals 54 protrude from the corresponding transition sidewalls 52. The outer shell 51 is in a straight line shape.

[0130] Example 3

[0131] This application includes most of the features of embodiment 1 in embodiment 3, except that the connector 500a in embodiment 1 is not H-shaped or cross-shaped, but L-shaped.

[0132] like Figure 18 , Figure 19 As shown in Embodiment 3 of this application, if the magnetic conductive tracks 100 need to be connected in an L-shape, the connector 500c is designed as an L-shaped structure, including a quadrilateral housing 51 and parallel transition sidewalls 52 extending from adjacent sides of the housing 51. The conductive terminal 54 includes a quadrilateral fixing portion 5541 and parallel electrical mating portions 5542 extending from adjacent sides of the fixing portion 5541. Therefore, the connector 500c can form mechanical and electrical connections with the conductive portions 22 at the ends of the two magnetic conductive tracks 100, respectively, and arrange the two magnetic conductive tracks 100 in an L-shape to form an L-shaped magnetic conductive track system.

[0133] In summary, in the L-shaped connector 500c, the housing 51 includes the two transition sidewalls 52 and the two pairs of conductive terminals 54; the two transition sidewalls 52 are perpendicular to each other and are used to connect the two vertical magnetic conductive tracks 100; the two pairs of conductive terminals 54 protrude from the corresponding transition sidewalls 52. The housing 51 is L-shaped.

[0134] The connector 500c can be an L-shaped structure in a horizontal plane, which can be used to connect two magnetic conductive tracks 100 in a horizontal plane; the connector 500c can also be an L-shaped structure in a vertical plane, which can be used to connect one magnetic conductive track 100 in a horizontal plane to one magnetic conductive track 100 in a vertical plane.

[0135] To facilitate the insertion of the adapter sidewall 52 of the outer casing 51 into the square insertion hole 110 at the end of the magnetic conductive track 100 and achieve a better visual effect, the outer casing 51 includes two vertically arranged protrusions 55, the end faces of which are configured as the adapter sidewall 52. The protrusions 55 extend into the square insertion hole 110 to achieve a seamless connection.

[0136] Example 4

[0137] Embodiment 4 of this application includes most of the features of Embodiment 1, except that it is not the H-type or cross-type structure of the connector 500a described in Embodiment 1, but a T-type.

[0138] like Figure 20 , Figure 21 As shown in Embodiment 4 of this application, if the magnetic conductive tracks 100 need to be connected in a T-shape, the connector 500d is designed as a T-shaped structure, including a quadrilateral housing 51 and three parallel transition sidewalls 52 extending continuously from the housing 51. The conductive terminal 54 includes a quadrilateral fixing portion 5541 and three parallel electrical mating portions 5542 extending continuously from the fixing portion 5541. Therefore, the connector 500d can form mechanical and electrical connections with the conductive portions 22 at the end positions of the three magnetic conductive tracks 100, and arrange the two magnetic conductive tracks 100 in a T-shape to form a T-shaped magnetic conductive track system.

[0139] In summary, in the T-shaped connector 500d, the housing 51 includes three vertically arranged transition sidewalls 52 and three pairs of conductive terminals 54. The three vertically arranged transition sidewalls 52 are used to connect the three magnetic conductive tracks 100; the three pairs of conductive terminals 54 protrude from the corresponding transition sidewalls 52. The housing 51 is T-shaped.

[0140] The connector 500d can be a T-shaped structure in a horizontal plane, suitable for connecting three magnetic conductive tracks 100 in a horizontal plane; the connector 500d can also be a T-shaped structure in a vertical plane, suitable for connecting two magnetic conductive tracks 100 in a horizontal plane with one magnetic conductive track 100 in a vertical plane, or for connecting one magnetic conductive track 100 in a horizontal plane with two magnetic conductive tracks 100 in a vertical plane.

[0141] To facilitate the insertion of the adapter sidewall 52 of the outer casing 51 into the square insertion hole 110 at the end of the magnetic conductive track 100 and achieve a better visual effect, the outer casing 51 includes three vertically arranged protrusions 55, the end faces of which are configured as the adapter sidewall 52. The protrusions 55 extend into the square insertion hole 110 to achieve a seamless connection.

[0142] As can be seen from the above embodiments, the connectors 500a, 500b, 500c, and 500d have different structures depending on the cascading method. The connectors 500a, 500b, 500c, and 500d with different structures are connected to multiple magnetic conductive tracks 100 to form magnetic conductive track systems with different structures. The magnetic conductive tracks 100 cascaded with connectors 500a, 500b, 500c, and 500d can magnetically attract and electrically connect with various electrical devices, which is convenient and reliable. The connectors are respectively planar in the form of a straight line, L-shape, convex shape, T-shape, H-shape, or cross shape. Therefore, the magnetic conductive track system composed of the connectors and at least two magnetic conductive tracks 100 is also planar. The magnetic conductive track system 1 is fitted to the surface of the mounting base, resulting in a flat and simple overall structure with low height, thinness, and convenient assembly, achieving a special effect of lightweight and thinness.

[0143] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

[0144] The connector, magnetic conductive track system, and lighting device provided in this application embodiment only require the connector to be inserted into the square opening and conductive groove at the end of the magnetic conductive track during installation. Installation is simple and convenient, and the mechanical structure is highly reliable. Furthermore, the connector contains at least one magnetic adsorption element, enabling the connector to be magnetically attracted, thus meeting the same fixing requirements as the magnetic conductive track. The connector includes various forms such as straight, L-shaped, convex, T-shaped, H-shaped, or cross-shaped structures, allowing for the connection of the magnetic conductive track in various ways, including straight, planar L-shaped, vertical L-shaped, cross-shaped, and T-shaped connections, to form a magnetic conductive track system. The overall structure is flat and simple, with low height and thinness, facilitating assembly and achieving a lightweight and thin design.

[0145] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

[0146] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
