Technical Field

[0002] This application relates to a track module and track system, belonging to the field of lighting technology. Background Technology

[0003] 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 modules on the market connect multiple track segments through mechanical connecting plates and achieve electrical connections between adjacent track segments through electrical connectors to meet the needs of different spatial layouts and sizes.

[0004] 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 mating and electrical connection of electrical connectors during mechanical connections increases the complexity of the installation and raises the professional requirements for installers, potentially affecting installation safety. Secondly, for existing track lighting systems using an integrated electromechanical power supply scheme, the frequent mating and disassembly of electrical connectors during track pre-installation inevitably damages the connector terminals, affecting normal user operation and increasing maintenance costs.

[0005] 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

[0006] The purpose of this application is to provide a track module that enables electrical connection between two adjacent track segments through two connectors, which not only provides a stable connection but also facilitates the installation or disassembly of the track module.

[0007] To achieve the above objectives, this application provides a track module, comprising:

[0008] At least two track segments, each track segment including an electric rail, the electric rail having a plurality of electrical conductors extending along its longitudinal direction;

[0010] 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 mate with the second connector on the adjacent track segment along the longitudinal direction when rotated to a state where it is inserted into the corresponding power rail and makes electrical contact with the electrical conductor, thereby connecting the two adjacent track segments mechanically and electrically.

[0011] Optionally, the first connector has a plug portion that is disposed toward the second connector along the longitudinal direction, and the second connector has a mating portion that mates with the plug portion.

The mating part is a mating groove provided on the second connector, and the mating terminal of the second connector is received in the mating groove. The plug-in groove and the mating groove are plugged in and engaged to make the contact terminal and the mating terminal electrically contact each other.

[0014] Optionally, the first connector includes a first body and a pivot portion disposed on the first body, and the first connector is rotatably connected to the corresponding track segment by means of the pivot portion.

[0015] Optionally, the first connector includes a first cover plate that mates with the first body, and the first cover plate is provided with a grip portion for rotating the first connector.

[0017] Optionally, the second connector includes a second body and a second insert plate disposed on the second body. The second insert plate is inserted into the corresponding power rail, so that the second connector is connected to the corresponding rail segment.

[0018] Optionally, it also includes a connecting plate between two adjacent track segments, the connecting plate being disposed at one end of one of the track segments, the first connector being mounted on the connecting plate and being rotatable relative to the connecting plate into the power rail inserted into the corresponding track segment.

[0019] Another objective of this application is to provide a track system having the aforementioned track module.

[0020] To achieve the above objectives, this application provides an orbital system, comprising:

[0021] The aforementioned track module;

[0022] The load device is mounted on the track section and electrically connected to the electrical conductor.

[0023] The beneficial effects of this application are as follows: The track module of this application, 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 the corresponding power rail and electrically contact the conductor, and thus can be connected mechanically and electrically to the second connector on the adjacent track segment along the longitudinal direction, thereby achieving mechanical and electrical connection between the two adjacent track segments. In this way, mechanical and electrical connection between two adjacent track segments can be achieved through the docking of the two connectors, which is simple to operate and facilitates the installation and disassembly of the track module.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Referring to Figures 1 to 15, this application discloses a track system including a track module 100 and a load device (not shown) mounted on the track module 100. The load device includes, but is not limited to, lighting fixtures, 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 electrical connection between two adjacent track segments 10, thereby energizing the load device mounted on the track segment 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 space availability. 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.

[0043] 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 longitudinal 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.

[0044] As shown in Figure 3, 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.

[0045] As shown in Figure 4, 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 in this application.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] As shown in Figures 1 and 6, 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. Specifically, the first connector 21 is rotatably connected to one of the track segments 10, allowing it to rotate and insert into the corresponding power rail 12 and electrically connect with the power conductor 123, thus achieving electrical connection between the first connector 21 and the corresponding track segment 10. The second connector 22 is installed on the other adjacent track segment 10, allowing it to insert into the corresponding power rail 12 and electrically connect with the power conductor 123, thus achieving electrical connection between the second connector 22 and the corresponding track segment 10. Furthermore, when the first connector 21 is rotated to a state of electrical contact with the corresponding power rail 12 and power conductor 123, it can mate longitudinally with the second connector 22 on the adjacent track segment 10, thus achieving mechanical and electrical connection between the two adjacent track segments 10. By setting a pivotable first connector 21 and a fixedly installed second connector 22, electrical connections and disconnections between multiple track segments 10 can be quickly achieved, improving the installation and disassembly efficiency of the track module 100.

[0050] As shown in Figures 2 and 5, 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 the power rail 12 of the corresponding track segment 10 to make electrical contact with the corresponding electrical conductor 123. The connecting plate 30 is located between the mechanical rail 11 and the power rail 12, with the power rail 12 extending onto the connecting plate 30. The first connector 21 protrudes from the connecting plate 30 onto the corresponding mechanical rail 11, while the second connector 22 is retracted into the corresponding mechanical rail 11 to reserve space for the insertion of the connecting plate 30. Thus, by inserting the connecting plate 30 into the adjacent mechanical rail 11, the two adjacent track segments 10 can be inserted into place along the first direction. At this time, the second connector 22 and the first connector 21 are simultaneously engaged, realizing the mechanical and electrical connection between the two track segments 10. In this embodiment, 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.

[0051] 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 the end of the base plate 31 away from the first connector 21 is located on the side of the protrusion 125 on the first side of the carrier 121. The two side plates 32 have abutment grooves 33 near the abutment protrusion 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 are snapped 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 and engaged in the second direction.

[0052] As shown in Figures 7-9, the first connector 21 includes two electrical connection portions: a first electrical connection portion 2121 and a second electrical connection portion 2122. The first electrical connection portion 2121 is used to insert into a corresponding power rail 12 and make electrical contact with a corresponding electrical conductor 123. The second electrical connection portion 2122 is used to electrically connect with a corresponding electrical connection portion of the second connector 22. The first connector 21 includes a plurality of first connecting members 211 adapted to a plurality of electrical conductors 123, a first body 213 for accommodating the first connecting members 211, and a first cover plate 214 that mates with the first body 213. The first cover plate 214 encapsulates the first connecting members 211 within the first body 213. The first connecting members 211 are spaced apart from each other, with two electrical connection portions located at both ends of the first connecting member 211 and partially exposed to the first body 213. Preferably, the first electrical connection portion 2121 and the second electrical connection portion 2122 are arranged perpendicularly to each other. Since the electrical conductors 123 in the power rail 12 are arranged in two rows, the multiple first connectors 211 in the first connector 21 are also arranged in two groups accordingly. The first connectors 211 in two adjacent groups are staggered in the first direction, and the first electrical connection portions 2121 of the first connectors 211 in two adjacent groups are staggered in the second direction. This arrangement allows the first electrical connection portions 2121 of the first connectors 211 to make electrical contact with the corresponding electrical conductors 123, thus avoiding circuit misalignment and short circuits. Of course, in other optional embodiments, when the power rail 12 only has a single row of electrical conductors 123, only one group of first connectors 211 is provided, and the problem of staggered arrangement of multiple first connectors 211 in a single group does not exist.

[0053] Specifically, the first connector 21 is a pivotable connector. The first connector 21 is rotatably connected to the corresponding track segment 10. During rotation, the first connector 21 has a connected position and a disconnected position with the corresponding power rail 12, as shown in Figures 15 and 16. Of course, in other alternative embodiments, the first connector 21 can also be directly inserted and fixed to the power rail 12 of the track segment 10, maintaining a connected position with the power rail 12; this is not limited. In the connected position, the first electrical connection portion 2121 of the first connector 21 is in electrical contact with the corresponding electrical conductor 123, and the second electrical connection portion 2122 faces the corresponding electrical connection portion of the second connector 22, facilitating both mechanical and electrical connection between adjacent track segments 10. In the disconnected position, the second electrical connection portion 2122 of the first connector 21 is offset from the corresponding electrical connection portion of the second connector 22, and the first electrical connection portion 2121 is electrically isolated from the corresponding electrical conductor 123. At this point, mechanical connection is made between two adjacent track segments 10, but electrical connection is not established between them. This avoids electrical connection between adjacent track segments 10 during pre-installation, ensuring installation safety and facilitating power disconnection. Furthermore, it prevents damage to the connectors themselves caused by frequent docking and disengagement of the first connector 21 and the second connector 22, reducing subsequent maintenance costs.

[0054] This simplified connection process makes installation more intuitive and easier, reducing the need for professional installers and saving installation time and costs. During installation, the track module 100 of this application only requires pivoting the first connector 21 to the connection position and then mating it with the second connector 22, which is convenient, quick, and labor-saving. Furthermore, electrical connection is only achieved when adjacent track segments 10 are mated at the connection position, increasing safety during installation and maintenance and reducing the risk of electric shock. When maintenance or upgrades to the track module 100 are required, separating the first connector 21 and the second connector 22 (electrical isolation) and pivoting the first connector 21 to the disconnect position not only disconnects the power but also simultaneously separates the adjacent track segments 10, facilitating the replacement of load equipment and overall track maintenance.

[0055] Specifically, the first electrical connection portion 2121 of the first connector 21 is disposed along a second direction, and the second electrical connection portion 2122 is disposed along a first direction, and are respectively partially exposed on adjacent sides of the first body 213. In this embodiment, the first cover plate 214 and the first body 213 of the first connector 21 are disposed along the second direction, that is, the first body 213 is disposed facing the power rail 12, while the first cover plate 214 is disposed away from the power rail 12. Both the first body 213 and the first cover plate 214 are made of insulating material, and a first receiving space 215 for partially receiving the first connector 211 is formed between the first body 213 and the first cover plate 214. Optionally, the first body 213 and the first cover plate 214 are detachably connected. Of course, in other embodiments, the first body 213 and the first cover plate 214 may also be integrally formed.

[0056] The first receiving space 215 is provided with a step frame 216 for mounting two sets of first connectors 211. In this embodiment, the two sets of first connectors 211 are mounted on the step frame 216 along a first direction and are partially received within the first receiving space 215. Optionally, the first body 213 and the step frame 216 are detachably connected. Of course, in other embodiments, the first body 213 and the step frame 216 can also be integrally formed. One set of the two sets of first connectors 211 surrounds the outside of the other set, such that the two sets of first connectors 211 are staggered in the first direction and the second direction. The first electrical connection portions 2121 of the two sets of first connectors 211 are preferably staggered in both the first and second directions, and the second electrical connection portions 2122 are preferably flush in the first direction and staggered in the second direction. The first connectors 211 are spaced apart from each other. The step frame 216 is provided with a second partition 2161 that separates a set of first connectors 211 surrounding the outside, and the set of first connectors 211 contacts the first cover plate 214. The first body 213 is provided with a first partition 2131 that separates another set of first connectors 211, and the other set of first connectors 211 is installed on the step surface of the step frame 216.

[0057] The first body 213 has multiple first through-holes 2132 on the side opposite to the first cover plate 214 for the first electrical connection portions 2121 of the two sets of first connectors 211 to extend out, so as to make electrical contact with the corresponding electrical conductors 123. The first body 213 has multiple first openings 2133 along its longitudinal direction toward the second connector 22 for exposing the second electrical connection portions 2122 of the two sets of first connectors 211. The second electrical connection portions 2122 and the first openings 2133 form a mating portion for mating with the second connector 22.

[0058] The first body 213 has several spaced first insert plates 217 on the side opposite to the first cover plate 214. The first insert plates 217 extend in a second direction so that they can be rotated into the gap between adjacent profiles 122 of the power rail 12, allowing the first connector 21 to connect with the corresponding rail segment 10. A first through-hole 2132 is located near the first insert plate 217, and the first insert plate 217 has 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, such as the first electrical connection portion 2121 shown in FIG8. The first electrical connection portion 2121 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 first electrical connection portion 2121 protruding from the receiving groove 2171 can make electrical contact with the corresponding electrical conductor 123. In the third direction, the first electrical connection portions 2121 of the first connectors 211 of different groups are staggered on the same first plug plate 217 and located on opposite sides of the first plug plate 217.

[0059] As shown in Figures 7-9, the first connector 21 is provided with a pivot portion 218 and a grip portion 219. Each first connector 211 has a first electrical connection portion 2121 and a second electrical connection portion 2122 intersecting at a connecting point. The pivot portion 218 can rotate along a rotation axis parallel to the connecting line formed by the intersection of the connecting points of the multiple first connectors 211. For example, this rotation axis can be the connecting line between the two pivot portions 218 as shown in Figure 7. 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 a connected position and a disconnected position. The grip portion 219 is configured to be rotatable relative to the pivot portion 218 about the rotation axis via a drive, facilitating the switching of the first connector 21 between the connected position and the disconnected position.

[0060] Specifically, the pivot portion 218 is located at the end of the first body 213 away from the second connector 22 along a first direction. The pivot portion 218 includes two lugs protruding from the first body 213. The lugs have rotating holes. As shown in FIG5, a mating portion 321 is provided on the side plate 32 of the connecting plate 30 corresponding to the position of the pivot portion 218. The mating portion 321 includes two protrusions extending away from the side plate 32. The two protrusions 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 through a pivot shaft. This application does not limit this.

[0061] The grip portion 219 is located at the end of the first cover plate 214 away from the pivot portion 218 along the first direction. By rotating the first connector 21 along the first direction (as shown in Figure 15, the grip portion 219 rotates counterclockwise) with the grip portion 219, the first connector 21 is positioned in the connected position, thereby achieving an electrical connection between the first connector 21 and the corresponding power rail 12. Conversely, by flipping the first connector 21 in the opposite direction to the first direction (as shown in Figure 16, the grip portion 219 rotates clockwise), the first connector 21 changes from the connected position to the disconnected position, thereby achieving a rapid disconnection of the first connector 21 from the corresponding rail segment 10.

[0062] As shown in Figures 10-13, the second connector 22 includes two electrical connection portions, namely a third electrical connection portion 2221 and a fourth electrical connection portion 2222. The third electrical connection portion 2221 is used to insert into the corresponding power rail 12 and make electrical contact with the corresponding electrical conductor 123. The fourth electrical connection portion 2222 is used to electrically connect with the second electrical connection portion 2122 of the first connector 21. The second connector 22 includes a plurality of second connecting members 221 adapted to a plurality of electrical conductors 123, a second body 223 for accommodating the second connecting members 221, and a second cover plate 224 that cooperates with the second body 223. The second cover plate 224 is used to encapsulate the second connecting members 221 within the second body 223. The second connecting members 221 are spaced apart from each other, with two electrical connection portions located at both ends of the second connecting member 221 and partially exposed to the second body 223. Preferably, the third electrical connection portion 2221 and the fourth electrical connection portion 2222 are arranged perpendicularly to each other. Since the electrical conductors 123 in the power rail 12 are arranged in two rows, the multiple second connectors 221 in the second connector 22 are also arranged in two groups accordingly. The second connectors 221 in adjacent groups are staggered in the first direction, and the third electrical connection portions 2221 of the second connectors 221 in adjacent groups are staggered in the second direction. This arrangement allows the third electrical connection portions 2221 of the second connectors 221 to make electrical contact with the corresponding electrical conductors 123, thus avoiding circuit misalignment and short circuits. Of course, in other optional embodiments, when the power rail 12 only has a single row of electrical conductors 123, only one group of second connectors 221 is provided, and the problem of staggered arrangement of multiple second connectors 221 in a single group does not exist.

[0063] The second connector 22 is inserted and fixed onto the power rail 12 of the adjacent track segment 10. The third electrical connection portion 2221 of the second connector 22 is disposed along a second direction, and the fourth electrical connection portion 2222 is disposed along a first direction, and are respectively partially exposed on adjacent sides of the second body 223. In this embodiment, the second cover plate 224 and the second body 223 of the second connector 22 are disposed along the second direction, that is, the second body 223 faces the power rail 12, while the second cover plate 224 faces away from the power rail 12. Both the second body 223 and the second cover plate 224 are made of insulating material, and a second receiving space 225 for partially accommodating the second connector 221 is formed between the second body 223 and the second cover plate 224. Optionally, the second body 223 and the second cover plate 224 are detachably connected. Of course, in other embodiments, the second body 223 and the second cover plate 224 can also be integrally formed.

[0064] The second receiving space 225 is provided with multiple fixing plates 226 for fixing the second connectors 221. In this embodiment, two sets of second connectors 221 are partially received in the second receiving space 225 along the first direction and are snapped and fixed to one side of the fixing plate 226. Two sets of fixing plates 226 are provided, spaced apart and staggered in the first direction, with multiple fixing 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 fixing plate 226, meaning multiple second connectors 221 in the same set are located on the same side of the corresponding fixing plate 226. The second cover plate 224, located within the second receiving space 225, has a support plate 2241 for supporting one set of the two sets of second connectors 221, with the other set of the two sets of second connectors 221 directly contacting the second cover plate 224. This results in the two sets of second connectors 221 being staggered in the first and second directions. The third electrical connection portion 2221 of the two sets of second connectors 221 is preferably staggered in both the first and second directions, and the fourth electrical connection portion 2222 is preferably flush in the first direction and staggered in the second direction.

[0065] The second body 223 has multiple second through-holes 2231 on the side opposite to the second cover plate 224 for the third electrical connection portion 2221 of each second connector 221 to extend out, so as to make electrical contact with the corresponding electrical conductor 123. The second body 223 has multiple second openings 2232 along its longitudinal direction facing the first connector 21 for exposing the fourth electrical connection portions 2222 of the two sets of second connectors 221. The fourth electrical connection portions 2222 and the second openings 2232 form mating portions for insertion and mating with the insertion portion of the first connector 21.

[0066] The second body 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 with the power rail 12, ensuring a fixed connection between the second connector 22 and the corresponding track segment 10 before insertion into the first connector 21. 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 third electrical connection portion 2221 of the second connector 221. The third electrical connection portion 2221 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 second insert plate 227 is inserted into the corresponding power rail 12. In the third direction, the third electrical connection portions 2221 of the second connectors 221 of different groups are staggered on the same second plug plate 227 and located on opposite sides of the second plug plate 227.

[0067] As shown in Figures 7-16, electrical connection between two adjacent track segments 10 is achieved through the mating part and the plug-in part. In this embodiment, the mating part is a contact terminal extending from the second body 223 of the second connector 22, and the plug-in part is a slot provided on the first body 213 of the first connector 21, into which the contact terminal is inserted. Specifically, the second opening 2232 is opened on the side of the second body 223 facing the first connector 21 along the longitudinal direction, and the fourth electrical connection part 2222 of the second connector 22 extends from the second opening 2232. The fourth electrical connection part 2222 is exposed as a mating part and is a contact terminal for plugging into the first connector 21. The first opening 2133 is opened on the side of the first body 213 facing the second connector 22 along the longitudinal direction, and the second electrical connection part 2122 of the first connector 21 is received in the first opening. The second electrical connection part 2122 serves as a plug-in part, a slot into which the fourth electrical connection part 2222 is inserted. Of course, in other alternative embodiments, the fourth electrical connection portion 2222 and the second electrical connection portion 2122 can also be configured to have a patch-type contact. In this case, the fourth electrical connection portion 2222 can be provided with a bent electrical connection end (not shown). The bending center of the electrical connection end can make close contact with the second electrical connection portion 2122 when the fourth electrical connection portion 2222 extends into the first opening 2133, thereby improving the stability of the electrical connection.

[0068] In some embodiments, the insertion portion is a contact terminal extending from the first body 213 of the first connector 21, and the mating portion is a slot provided on the second body 223 of the second connector 22, through which the contact terminal is inserted. Specifically, a first opening 2133 is formed on the side of the first body 213 facing the second connector 22 along the longitudinal direction, and a second electrical connection portion 2122 of the first connector 21 extends out corresponding to the first opening 2133. The second electrical connection portion 2122 is exposed as an insertion portion and is a contact terminal for insertion and mating with the second connector 22. A second opening 2232 is formed on the side of the second body 223 facing the first connector 21 along the longitudinal direction, and a fourth electrical connection portion 2222 of the second connector 22 is received within the second opening 2232. The fourth electrical connection portion 2222 serves as a mating portion and is a slot for the second electrical connection portion 2122 to be inserted. Of course, in other alternative embodiments, the fourth electrical connection portion 2222 and the second electrical connection portion 2122 may also be provided in a patch-type contact. At this time, a curved electrical connection end (not shown) may be provided on the second electrical connection portion 2122. The bending center of the electrical connection end can make close contact with the fourth electrical connection portion 2222 when the second electrical connection portion 2122 extends into the second opening 2232, thereby improving the stability of the electrical connection.

[0069] In other embodiments, the insertion portion is an insertion slot provided on the first body 213 of the first connector 21, and the contact terminal of the first connector 21 is received in the insertion slot. The mating portion is a mating slot provided on the second body 223 of the second connector 22, and the mating terminal of the second connector 22 is received in the mating slot. The insertion slot and the mating slot are inserted and engaged to make the contact terminal and the mating terminal electrically contact each other. Specifically, the first opening 2133 protrudes from the first body 213 along the longitudinal direction toward the second connector 22, and the second electrical connection portion 2122 of the first connector 21 extends out of the first receiving space 215 and is received in the first opening 2133. The first opening 2133 serves as the insertion slot, and the second electrical connection portion 2122 is the contact terminal received in the insertion slot. The second opening 2232 protrudes from the second body 223 along the longitudinal direction toward the first connector 21, and the fourth electrical connection portion 2222 of the second connector 22 extends out of the second receiving space 225 and is received in the second opening 2232. The second opening 2232 serves as a mating groove, and the fourth electrical connection part 2222 is a mating terminal housed within the mating groove. The first opening 2133 and the second opening 2232 are inserted into each other, allowing the second electrical connection part 2122 and the fourth electrical connection part 2222 to make electrical contact, thus achieving an electrical connection between two adjacent track segments 10. There is no restriction on whether the contact terminals and mating terminals use pin and socket contact methods or surface mount contact methods.

[0070] In summary, the track module 100 of this application achieves mechanical and electrical connection between adjacent track segments 10 by rotating a first connector 21 to one of the track segments 10 and installing a second connector 22 to an adjacent track segment 10. This allows the first connector 21 to be rotated to a position where it makes electrical contact with the corresponding power rail 12 and the electrical conductor 123, and then docking with the second connector 22 on the adjacent track segment 10 along its longitudinal direction. Thus, the mechanical and electrical connection between adjacent track segments 10 can be achieved through the docking of the two connectors. This method is simple to operate and facilitates the installation and disassembly of the track module 100.
