Description

Technical Field

[0001] This invention relates to a track module and track system, belonging to the field of lighting technology. Background Technology

[0002] In the lighting field, track lights are widely used in various scenarios such as commercial, residential, and industrial applications due to their flexible installation methods and efficient lighting effects. Most track systems on the market connect multiple track sections using mechanical connecting plates and achieve electrical connections between adjacent track sections through electrical connectors to meet the needs of different spatial layouts and sizes.

[0003] However, existing track lighting systems have shown significant shortcomings in terms of installation safety, system maintenance, and track section replacement. Firstly, during installation, ensuring proper alignment and electrical connection of electrical connectors during mechanical assembly increases the complexity of the installation and raises the professional requirements for installers, potentially impacting installation safety. Secondly, existing track lighting systems typically require a complete power outage when maintenance or replacement is needed, rendering the entire system unusable during maintenance. This not only disrupts normal user operation but also increases the difficulty and risk of maintenance.

[0004] In view of this, it is indeed necessary to provide a track module and track system to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a track module that enables mechanical and electrical connection between two adjacent track segments via two connectors, thereby facilitating operation.

[0006] To achieve the above objectives, the present invention provides a track module, comprising:

[0007] At least two track segments, each track segment including an electric rail, the electric rail having a plurality of electrical conductors extending along a first direction;

[0008] At least one electrical connector group, each electrical connector group comprising two connectors respectively inserted into a corresponding power rail and electrically connected to an electrical conductor;

[0009] The two connectors include a first connector rotatably connected to one of the track segments and a second connector mounted to an adjacent track segment. The first connector is configured to be mechanically connected to or separated from the second connector in a second direction perpendicular to the first direction when the two adjacent track segments are mated in a first direction, thereby mechanically and electrically connecting or isolating the two adjacent track segments.

[0010] As a further improvement of the present invention, each connector includes two electrical connection parts, one of which is used to be inserted into the corresponding power rail and make electrical contact with the corresponding electrical conductor, and the other is used to be electrically connected to the corresponding electrical connection part of another connector.

[0011] As a further improvement of the present invention, each connector includes a plurality of connectors adapted to a plurality of electrical conductors, a base for accommodating the connectors, and a cover plate that mates with the base, with two electrical connection portions located at both ends of the connectors and partially exposed to the base and / or the cover plate.

[0012] As a further improvement of the present invention, the electrical conductors in the power rail are arranged in multiple rows, and the multiple connectors in each connector are also arranged in multiple groups accordingly. The adjacent groups of connectors are staggered in the first direction, and the corresponding electrical connection parts of the adjacent groups of connectors are staggered in the second direction.

[0013] As a further improvement of the present invention, the two electrical connection portions of the first connector extend in the same direction relative to the corresponding connector and are partially exposed on the same side of the base, and the two electrical connection portions of the second connector extend in opposite directions relative to the corresponding connector and are respectively partially exposed on the base and the cover plate.

[0014] As a further improvement of the present invention, the electrical connection portion of the first connector that is electrically connected to the second connector is a contact terminal extending out of the base, and the cover plate of the second connector is provided with a receiving groove for the contact terminal to be inserted into and to contact the corresponding electrical connection portion.

[0015] As a further improvement of the present invention, the electrical connection portion of the second connector that is electrically connected to the first connector is a contact terminal that extends out of the cover plate, and the base of the first connector is provided with a corresponding receiving groove for the contact terminal to be inserted into and contact the corresponding electrical connection portion.

[0016] As a further improvement of the present invention, the contact terminal is housed in the slot protruding from the corresponding base or cover plate, the receiving groove protrudes from the corresponding base or cover plate, and the receiving groove is inserted into the slot to realize the electrical connection between the first connector and the second connector.

[0017] As a further improvement of the present invention, the track module also includes a connecting plate connected between two adjacent track segments. The connecting plate is disposed at one end of one of the track segments, and a first connector is mounted on the connecting plate and is rotatable relative to the connecting plate to be inserted into a second connector of the adjacent track segment.

[0018] The purpose of this invention is to provide a track system having the above-mentioned track module.

[0019] To achieve the above objectives, the present invention provides a track system comprising:

[0020] The aforementioned track module;

[0021] The load device is mounted on the track section and electrically connected to the electrical conductor.

[0022] The beneficial effects of this invention are as follows: The track module of this invention, by rotating the first connector of two connectors to one of the track segments and installing the second connector to the adjacent track segment, allows the first connector to be inserted into or separated from the second connector in a second direction perpendicular to the first direction while the two adjacent track segments are mated along a first direction, thus enabling mechanical and electrical connection or isolation between the two adjacent track segments. In this way, mechanical and electrical connection between two adjacent track segments can be achieved simply by rotating the first connector, making operation simple and convenient.

[0044] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] Please see Figures 1 to 15As shown, this invention discloses a track system, including a track module 100 and a load device (not shown) assembled on the track module 100. The load device includes, but is not limited to, lights, sensors, power supplies, etc. The track module 100 includes at least two track segments 10 and at least one electrical connector group 20. The electrical connector group 20 enables mechanical and electrical connections between adjacent track segments 10, thereby energizing the load device assembled on the track segments 10. Users can set multiple track segments 10 according to their needs and splice them together using the electrical connector group 20, thus allowing for reasonable planning of the track system layout based on available space. Furthermore, the splicing shape of the multiple track segments 10 can be flexibly designed according to the installation environment. For example, straight lines, rectangles, squares, etc.

[0046] Each track segment 10 includes a mechanical guide rail 11 and an electrical guide rail 12 located within the mechanical guide rail 11. Each mechanical guide rail 11 has a mounting slot 113 for mounting the electrical guide rail 12. The load device is mounted on the mechanical guide rail 11 and electrically connected to the electrical guide rail 12. Since the electrical guide rail 12 is disposed within the mechanical guide rail 11, both have the same length, width, and height directions. For ease of description, the length direction of the mechanical guide rail 11 is defined as the first direction, the height direction as the second direction, and the width direction as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0047] like Figure 3 As shown, the mechanical guide rail 11 is used for installation on the walls or ceilings of a building and is generally made of metal. The mechanical guide rail 11 includes a bottom wall 111 and two side walls 112 arranged along the length of the bottom wall 111 on both sides. A mounting groove 113 is formed between the bottom wall 111 and the side walls 112. In this embodiment, the mounting groove 113 is approximately U-shaped. This makes the rail as a whole strip, which is easier to grip and install. The mounting groove 113 has a downward-facing mounting opening. The power rail 12 is installed into the mounting groove 113 of the mechanical guide rail 11 through the mounting opening. Further, the ends of the two side walls 112 of the mechanical guide rail 11 near the bottom wall 111 protrude into the mounting groove 113 to form abutment protrusions 114. These abutment protrusions 114 are used to fix the power rail 12, so that the power rail 12 can be installed into the mounting groove 113 of the mechanical guide rail 11 without tools.

[0048] like Figure 4As shown, the power rail 12 includes a carrier 121 having a first side and a second side. The first and second sides are arranged opposite to each other, with the first side facing the bottom wall 111 and the second side facing away from the mechanical rail 11 and towards the mounting opening. The carrier 121 has abutment portions 124 for engaging with abutment protrusions 114 of the mechanical rail 11 to fix the power rail 12 into the mounting groove 113 of the mechanical rail 11. When the two abutment portions 124 overlap the two abutment protrusions 114, the protrusion 125 on the first side abuts against the bottom wall 111 to install the power rail 12 onto the mechanical rail 11 in a tool-free installation manner. In other embodiments, the power rail 12 can also be installed onto the mechanical rail 11 in other ways, such as by screws or welding, which is not limited by the present invention.

[0049] The carrier 121 has a plurality of profiles 122 protruding from its second side and a plurality of electrical conductors 123 disposed on the profiles 122. Specifically, the plurality of profiles 122 are disposed on the second side and extend in a direction away from the first side. Both the carrier 121 and the profiles 122 are made of insulating materials, such as plastic. The electrical conductors 123 are made of conductive metal materials, such as copper or copper alloys. In this embodiment, the carrier 121, the profiles 122, and the electrical conductors 123 all extend in a first direction. The carrier 121, the profiles 122, and the electrical conductors 123 are integrally injection molded or extruded. This arrangement reduces the processing steps and lowers costs.

[0050] In this embodiment, the power rail 12 is generally arranged in a comb shape. Profiles 122 are spaced apart along a third direction. A gap is formed between two adjacent profiles 122 in the third direction. A groove 1221 for accommodating an electrical conductor 123 is formed on the side of the profile 122 facing the gap. Several electrical conductors 123 are respectively disposed in corresponding grooves 1221 to draw power from the inner side of the gap. At least one groove 1221 is provided on the profile 122. This groove 1221 is constructed on the side of each profile 122. This groove 1221 communicates with the gap. The grooves 1221 on two adjacent profiles 122 facing the same gap are staggered. The electrical conductor 123 is received within the groove 1221 and is at least exposed to the gap to achieve electrical connection with the electrical connector assembly 20 or the load device.

[0051] In this embodiment, each profile 122 has two grooves 1221 with opposite opening directions and a height difference. That is, the two grooves 1221 with opposite opening directions are staggered in the second direction. One groove 1221 faces the gap opening, and the other faces away from the gap opening. Two grooves 1221 on adjacent profiles 122 at the same distance from the carrier 121 have the same opening direction. The electrical conductor 123 is disposed in the groove 1221. Therefore, the line connecting the electrical conductors 123 at the same distance from the carrier 121 is a straight line, which can avoid the occurrence of circuit confusion. In this embodiment, the electrical conductors 123 are arranged in two rows. Of course, in other optional embodiments, the electrical conductors 123 can also be arranged in a single row or multiple rows according to specific needs, and each profile 122 has one or more grooves 1221 communicating with the gap for installing the electrical conductors 123. There is no limitation on this.

[0052] like Figure 6 As shown, each electrical connector group 20 includes two connectors that mate and connect, namely a first connector 21 and a second connector 22. The first connector 21 and the second connector 22 are respectively disposed on two adjacent track segments 10, and are respectively inserted into corresponding power rails 12 and electrically connected to electrical conductors 123. This invention enables mechanical and electrical connections between two adjacent track segments 10 through two connectors, making operation simple and convenient. Specifically, the first connector 21 is rotatably connected to one of the track segments 10, and the second connector 22 is fixedly installed on the other adjacent track segment 10. Furthermore, the first connector 21 is configured to be mechanically connected or separated from the second connector 22 in a second direction perpendicular to the first direction when the two adjacent track segments 10 are mated along a first direction, thus enabling mechanical and electrical connections or isolation between the two adjacent track segments 10. By providing a pivotable first connector 21 and a fixedly installed second connector 22, electrical connections or isolation between multiple track segments 10 can be quickly achieved, improving the installation and disassembly efficiency of the track module 100.

[0053] like Figure 1 and Figure 5As shown, in this embodiment, the track module 100 further includes a connecting plate 30 connecting two adjacent track segments 10. The connecting plate 30 protrudes from one end of one of the track segments 10. A first connector 21 is mounted on the connecting plate 30 and can rotate relative to the connecting plate 30 to insert into a second connector 22 of the adjacent track segment 10. The connecting plate 30 is located between the mechanical guide rail 11 and the power guide rail 12, with the power guide rail 12 extending onto the connecting plate 30. The first connector 21 protrudes from the connecting plate 30 onto the corresponding mechanical guide rail 11, and the corresponding second connector 22 is recessed into the corresponding mechanical guide rail 11 to reserve space for the insertion of the connecting plate 30. Thus, by inserting the connecting plate 30 into the adjacent mechanical guide rail 11, the two adjacent track segments 10 can be inserted into each other along the first direction. In other words, the connecting plate 30 has the same shape as the mechanical guide rail 11 and can be inserted into the mechanical guide rail 11 from the longitudinal direction, thereby realizing the mechanical connection of the two track segments 10.

[0054] The connecting plate 30 includes a base plate 31 and two side plates 32 disposed on both sides of the base plate 31. The base plate 31 abuts against the bottom wall 111 of the mechanical guide rail 11, and one end of the base plate 31 away from the first connector 21 abuts against a protrusion 125 on the first side surface of the carrier 121. The two side plates 32 have abutment grooves 33 near the abutment protrusions 114 of the mechanical guide rail 11 to match the side walls 112 of the mechanical guide rail 11. Preferably, the ends of the two side walls 112 of the mechanical guide rail 11 away from the bottom wall 111 are bent into the assembly groove 113 to form snap-fit ​​grooves 115. The ends of the two side plates 32 snap into the snap-fit ​​grooves 115 of the mechanical guide rail 11. Through the abutment of the base plate 31 against the bottom wall 111 and the abutment of the ends of the side plates 32 against the snap-fit ​​grooves 115, the connecting plate 30 and the mechanical guide rail 11 are locked together in the second direction.

[0055] like Figures 7-9As shown, the first connector 21 includes two electrical connection portions. One electrical connection portion is used to insert into the corresponding power rail 12 and make electrical contact with the corresponding electrical conductor 123. The other electrical connection portion is used to make electrical connection with the corresponding electrical connection portion of the second connector 22. The first connector 21 includes a plurality of first connectors 211 adapted to the plurality of electrical conductors 123, a first base 213 for accommodating the first connectors 211, and a first cover plate 214 that cooperates with the first base 213. The first cover plate 214 is used to encapsulate the first connectors 211 within the first base 213. The first connectors 211 are spaced apart from each other, and two electrical connection portions are located at both ends of the first connectors 211 and are partially exposed to the first base 213. Since the plurality of electrical conductors 123 in the power rail 12 are arranged in two rows, the plurality of first connectors 211 in the first connector 21 are also correspondingly arranged in two groups. The first connectors 211 in the two adjacent groups are staggered in the first direction, and the corresponding electrical connection portions of the first connectors 211 in the two adjacent groups are staggered in the second direction. This configuration allows the corresponding electrical connection portion of the first connector 211 to make electrical contact with the corresponding electrical conductor 123.

[0056] In the first direction, the electrical connection portion of the first connector 21 for electrical connection with the second connector 22 is defined as the first electrical connection portion 2121, and the electrical connection portion of the first connector 21 for contact with the corresponding electrical conductor 123 is defined as the second electrical connection portion 2122.

[0057] Specifically, the first connector 21 is a pivotable connector. During rotation, the first connector 21 has a connected position and a disconnected position, such as... Figure 14 and Figure 15As shown. In the connected position, the second electrical connection portion 2122 of the first connector 21 is electrically in contact with the corresponding electrical conductor 123, and the first electrical connection portion 2121 is electrically connected to the second connector 22, thereby realizing the electrical connection of the two power rails 12. In the disconnected position, the first electrical connection portion 2121 of the first connector 21 is electrically isolated from the second connector 22, and preferably the second electrical connection portion 2122 of the first connector 21 is also electrically isolated from the electrical conductor 123 of its corresponding power rail 12, which not only ensures the safety of installation, but also enables rapid power disconnection. Through this simplified connection process, the installation process becomes more intuitive and easier to operate, reducing the need for professional installers and saving installation time and costs. The track module 100 of the present invention only requires pivoting the first connector 21 to the connected position for electrical connection during installation, which is convenient, quick, and saves time and effort. Furthermore, only in the connected position can adjacent track segments 10 be electrically connected, increasing the safety during installation and maintenance and reducing the risk of electric shock. When maintenance or upgrades to the track module 100 are required, the first connector 21 can be pivoted to the disconnected position for quick power-off, facilitating the replacement of load equipment and module maintenance. Furthermore, the pivotable first connector 21 allows the track module 100 to adapt to different installation environments and lighting requirements, providing greater flexibility and adaptability.

[0058] Specifically, the two electrical connection portions of the first connector 21 extend in the same direction relative to the corresponding first connector 211 and are partially exposed on the same side of the first base 213. Specifically, the first base 213 of the first connector 21 includes two end portions 2131 and a middle portion disposed along a first direction. The first cover plate 214 and the first base 213 are disposed along a second direction, i.e., the first base 213 faces the power rail 12, while the first cover plate 214 faces away from the power rail 12. Both the first base 213 and the first cover plate 214 are made of insulating material, and a first receiving space 215 for partially accommodating the first connector 211 is formed between the first base 213 and the first cover plate 214. Optionally, the first base 213 and the first cover plate 214 are detachably connected. Of course, in other embodiments, the first base 213 and the first cover plate 214 may also be integrally formed.

[0059] The first receiving space 215 is provided with a plurality of partitions 216 for separating the first connectors 211. In this embodiment, the first connectors 211 are partially received in the first receiving space 215 along a first direction, and the first connectors 211 in different groups are relatively staggered, such that in the first direction, the first electrical connection portions 2121 and the second electrical connection portions 2122 of the first connectors 211 in different groups are staggered. The two first connectors 211 in different groups are located on opposite sides of the partitions 216, that is, multiple first connectors 211 in the same group are located on the same side of the corresponding partitions 216. Of course, in other optional embodiments, when only a single row of several electrical conductors 123 is provided in the power rail 12, only one group of first connectors 211 is provided, and there is no problem of staggered arrangement of multiple first connectors 211 in a single group.

[0060] The first base 213 has a plurality of first through-holes 2132 on the side opposite to the first cover plate 214 for the two electrical connection portions of each first connector 211 to extend out, so as to make electrical contact or electrical connection with the corresponding electrical conductor 123 and the second connector 22 respectively. The two electrical connection portions of each first connector 211 are preferably located on the side of the first base 213 opposite to the first cover plate 214 and are respectively located near the two ends 2131.

[0061] One end of the first base 213 is provided with a plurality of spaced first insert plates 217. These first insert plates 217 extend away from the first cover plate 214 along a second direction, so that they can be inserted into the gaps between adjacent profiles 122 of the power rail 12. Near one of the two ends 2131, away from the second connector 22, the first insert plate 217 is provided with a first receiving groove 2171 communicating with the first through-hole 2132. The first receiving groove 2171 is used to receive one of the electrical connection portions of the first connector 211, for example... Figure 8 The second electrical connection portion 2122 is shown. The second electrical connection portion 2122 of the first connector 211 extends into the first receiving groove 2171 and partially protrudes from the first receiving groove 2171 so that when the first insert plate 217 is inserted into the corresponding power rail 12, the portion of the second electrical connection portion 2122 protruding from the first receiving groove 2171 can make electrical contact with the corresponding electrical conductor 123. In the second direction, the second electrical connection portions 2122 of different sets of first connectors 211 are staggered on the same first insert plate 217 and located on opposite sides of the first insert plate 217; the first electrical connection portions 2121 of the two sets of first connectors 211 are flush.

[0062] like Figures 7-9As shown, the first connector 21 has a pivot portion 218 and a grip portion 219. A connecting line exists between the first electrical connection portion 2121 and the second electrical connection portion 2122 of each first connector 211. The pivot portion 218 can rotate along a rotation axis perpendicular to the connecting line between the two electrical connections. For example, this rotation axis could be as follows: Figure 7 The line connecting the two pivot portions 218 is shown. In this embodiment, the first connector 21 is pivotally connected to the connecting plate 30 via the pivot portion 218, allowing the first connector 21 to rotate relative to the connecting plate 30 along the rotation axis, thereby quickly switching between the connected and disconnected positions. The grip portion 219 is configured to be rotatable relative to the pivot portion 218 about the rotation axis via a drive, to facilitate switching of the first connector 21 between the connected and disconnected positions.

[0063] Specifically, the pivot portion 218 is located on one end 2131 of the first base 213 along a first direction. For example... Figure 5 As shown, the pivot portion 218 includes two lugs protruding from the first base 213. The lugs have rotating holes. A mating portion 321 is provided on the side plate 32 of the connecting plate 30 corresponding to the pivot portion 218. The mating portion 321 includes two protruding posts extending away from the side plate 32. The two protruding posts are respectively inserted into the rotating holes of the two lugs, thereby enabling the pivot portion 218 to be pivotally connected to the connecting plate 30. It should be noted that the pivot portion 218 can also be pivotally connected to the mating portion 321 of the connecting plate 30 in other ways, such as via a pivot shaft. This invention does not limit this.

[0064] The grip portion 219 is located on the other end 2131 of the first cover plate 214, away from the pivot portion 218, along a first direction. The grip portion 219 is positioned along the first direction (e.g.,...) Figure 15 The first connector 21 is rotated counterclockwise by the gripping part 219 to the connection position, thereby establishing an electrical connection between the two power rails 12. Conversely, the first connector 21 is rotated counterclockwise by the gripping part 219 in the opposite direction to the first direction (e.g., ...). Figure 14 The middle grip 219 flips the first connector 21 in a clockwise direction, changing the first connector 21 from the connected position to the disconnected position, thereby realizing the rapid power disconnection between the first connector 21, the second connector 22, and the track segment 10.

[0065] like Figures 10-12As shown, the second connector 22 includes two electrical connection portions. One electrical connection portion is used to insert into the corresponding power rail 12 and make electrical contact with the corresponding electrical conductor 123. The other electrical connection portion is used to make electrical connection with the corresponding electrical connection portion of the first connector 21. The second connector 22 includes a plurality of second connectors 221 adapted to the plurality of electrical conductors 123, a second base 223 for accommodating the second connectors 221, and a second cover plate 224 that cooperates with the second base 223. The second cover plate 224 is used to encapsulate the second connectors 221 within the second base 223. The second connectors 221 are spaced apart from each other, with two electrical connection portions located at both ends of the second connectors 221 and partially exposed to the second base 223 and the second cover plate 224, respectively. Since the plurality of electrical conductors 123 in the power rail 12 are arranged in two rows, the plurality of second connectors 221 in the second connector 22 are also correspondingly arranged in two groups. The second connectors 221 in two adjacent groups are offset in the first direction, and the corresponding electrical connection portions of the second connectors 221 in two adjacent groups are offset in the second direction. This arrangement allows the corresponding electrical connection portions of the second connectors 221 to make electrical contact with the corresponding electrical conductors 123.

[0066] The second connector 22 is inserted and fixed onto the power rail 12 of the adjacent track segment 10. The two electrical connection portions of the second connector 22 extend in opposite directions relative to the corresponding second connector 221, and are respectively partially exposed on the second base 223 and the second cover plate 224. In the second direction, the electrical connection portion of the second connector 22 for electrical connection with the first connector 21 is defined as the third electrical connection portion 2221, and the electrical connection portion of the first connector 21 for contact with the corresponding electrical conductor 123 is defined as the fourth electrical connection portion 2222.

[0067] Specifically, the second cover plate 224 and the second base 223 are arranged along a second direction, that is, the second base 223 is arranged facing the power rail 12, while the second cover plate 224 is arranged away from the power rail 12. Both the second base 223 and the second cover plate 224 are made of insulating material, and a second receiving space 225 is formed between the second base 223 and the second cover plate 224 for partially accommodating the second connector 221. Optionally, the second base 223 and the second cover plate 224 are detachably connected. Of course, in other embodiments, the second base 223 and the second cover plate 224 may also be integrally formed.

[0068] The second receiving space 225 is provided with a plurality of mounting plates 226 for mounting the second connectors 221. In this embodiment, the second connectors 221 are partially received in the second receiving space 225 along the second direction and are snapped and fixed to one side of the mounting plate 226. Two sets of mounting plates 226 are provided, spaced apart and staggered in the first direction, with multiple mounting plates 226 in the same set spaced apart in the third direction. In this embodiment, two second connectors 221 from different sets are snapped and fixed to different sides of the mounting plate 226, that is, multiple second connectors 221 in the same set are located on the same side of the corresponding mounting plate 226. The second base 223 has a plurality of second through-holes 2231 on the side opposite to the second cover plate 224 for the fourth electrical connection portion 2222 of each second connector 221 to extend out, so as to make electrical contact with the corresponding electrical conductor 123. The second cover plate 224 has a receiving groove 2241 corresponding to each second connector 221, which exposes the third electrical connection portion 2221 of each second connector 221 so as to electrically connect with the first connector 21.

[0069] The second base 223 has several spaced second insert plates 227 on the side opposite to the second cover plate 224. The second insert plates 227 extend in a second direction to facilitate insertion into the power rail 12. The gaps between the insert plates 227 and the profiles 122 enable mechanical connection between the insert plates 227 and the power rail 12. A second through-hole 2231 is located near the second insert plates 227, and the second insert plates 227 have a second receiving groove 2271 communicating with the second through-hole 2231 to receive the fourth electrical connection portion 2222 of the second connector 221. The fourth electrical connection portion 2222 of the second connector 221 extends into and protrudes from the second receiving groove 2271, enabling electrical contact with the corresponding conductor 123 when the first insert plate 217 is inserted into the corresponding power rail 12. In the second direction, the fourth electrical connection portions 2222 of the second connectors 221 of different groups are staggered on the same second insert plate 227 and located on opposite sides of the second insert plate 227; the third electrical connection portions 2221 of the two groups of second connectors 221 are flush.

[0070] like Figures 7-15As shown, in this embodiment, the first electrical connection portion 2121 on the first connector 21, which is electrically connected to the second connector 22, is a contact terminal extending from the first base 213. The second cover plate 224 of the second connector 22 is provided with a receiving groove 2241 for the contact terminal to be inserted into and contact the corresponding third electrical connection portion 2221. The contact terminal is exposed and includes a bent electrical connection end 2123, wherein the bending center of the electrical connection end 2123 is used to contact the corresponding third electrical connection portion 2221 when inserted into the receiving groove 2241 to achieve electrical connection. This arrangement allows for a tighter contact between the first electrical connection portion 2121 and the third electrical connection portion 2221, improving the stability of the electrical connection. Of course, in other optional embodiments, the third electrical connection portion 2221 can be configured as a socket for the contact terminal to be inserted, thereby improving the stability of the electrical connection. Preferably, the first base 213 of the first connector 21 is provided with a protruding matching slot (not shown), the contact terminal is received within the matching slot, and the contact terminal is spaced apart from the inner peripheral wall of the matching slot. The receiving groove 2241 protrudes from the second cover plate 224 of the second connector 22, and the third electrical connection portion 2221 of the second connector 22 extends into the receiving groove 2241. When the receiving groove 2241 is engaged with the slot, the contact terminal makes electrical contact with the third electrical connection portion 2221, thereby achieving an electrical connection between the first connector 21 and the second connector 22. This engagement of the receiving groove 2241 with the slot increases the mechanical connection strength between the contact terminal and the third electrical connection portion 2221.

[0071] In some embodiments, the third electrical connection portion 2221 on the second connector 22, which is electrically connected to the first connector 21, is a contact terminal extending out of the second cover plate 224. The first base 213 of the first connector 21 has a corresponding receiving groove (not shown) for the contact terminal to be inserted into and contact the corresponding first electrical connection portion 2121. The contact terminal is exposed and includes a bent electrical connection end, wherein the bending center of the electrical connection end is used to contact the corresponding first electrical connection portion 2121 when inserted into the receiving groove to achieve electrical connection. This configuration allows for a tighter contact between the first electrical connection portion 2121 and the third electrical connection portion 2221, improving the stability of the electrical connection. Of course, in other alternative embodiments, the first electrical connection portion 2121 can be configured as a socket for the contact terminal to be inserted, thereby improving the stability of the electrical connection. Preferably, the second cover plate 224 of the second connector 22 has a protruding matching slot (not shown), the contact terminal is received within the matching slot, and the contact terminal is spaced apart from the inner peripheral wall of the matching slot. The receiving groove protrudes from the first base 213 of the first connector 21, and the first electrical connection portion 2121 of the first connector 21 extends into the receiving groove. When the receiving groove is engaged with the slot, the contact terminal makes electrical contact with the first electrical connection portion 2121, thereby achieving an electrical connection between the first connector 21 and the second connector 22. This engagement of the receiving groove with the slot increases the mechanical connection strength between the contact terminal and the first electrical connection portion 2121.

[0072] In summary, the track module 100 of the present invention, by distributing two connectors (21, 22) on two adjacent track segments 10 and electrically connecting them to the corresponding conductors 123, allows the first connector 21 to be rotatably connected to one of the track segments 10, and the second connector 22 to be installed on the other adjacent track segment 10. Thus, when the two adjacent track segments 10 are aligned along a first direction, the first connector 21 can be inserted into or separated from the second connector 22 along a second direction perpendicular to the first direction, enabling mechanical and electrical connection or isolation between the two adjacent track segments. Compared to the prior art, the track module 100 of the present invention achieves mechanical and electrical connection between two adjacent track segments 10 simply by rotating the first connector 21, making operation simple and convenient.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
