Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a track, adapter, and electrical system. Background Technology

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

[0003] Typically, the track is a linear track with mounting grooves for installing conductive components. The conductive components are inserted into or passed through these grooves from the front or back of the track to secure them, thus providing the electrical foundation for the electrical connection between the track and the adapter. However, this method of installing conductive components only works for linear tracks. For non-linear tracks such as circular or arc-shaped tracks, installation is extremely inconvenient, and it's impossible to connect linear and non-linear tracks. Only conductive connectors can be used, resulting in numerous electrical contact points, unstable electrical connections, and potential safety hazards.

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

[0005] The purpose of this invention is to provide a track that is simple in structure, easy to install, and can interconnect linear and non-linear tracks.

[0006] To achieve the above objectives, the present invention provides a track for coupling electrical equipment, comprising a main body and a coupling element disposed within the main body. The main body includes a mounting portion fixedly mounted on a mounting base and a frame disposed away from the mounting portion along the height direction. The frame encloses an accommodating space with an opening direction away from the mounting portion. The inner sidewall of the frame facing the accommodating space is provided with a mounting groove for snap-fit ​​connection with the coupling element. The upper and lower surfaces of the mounting groove extend towards each other to form a pair of first snap-fit ​​portions. The coupling element is provided with a pair of second snap-fit ​​portions corresponding to the positions of the first snap-fit ​​portions. The coupling element is pressed and installed into the mounting groove from within the accommodating space through the cooperation of the first snap-fit ​​portions and the second snap-fit ​​portions.

[0007] As a further improvement of the present invention, each of the first buckle portions includes a first guide slope and a first limiting portion set at an included angle, the first guide slope being disposed away from the inner sidewall relative to the first limiting portion, and the included angle being an acute angle.

[0008] As a further improvement of the present invention, the two ends of the coupling element, which are arranged opposite each other along the height direction, extend toward the inner sidewall to form extension portions. A pair of second buckle portions extend from the ends of the two extension portions toward each other in a direction away from each other. Each includes a second guide slope and a second limiting portion. The second guide slope is arranged toward the inner sidewall relative to the second limiting portion.

[0009] As a further improvement of the present invention, the coupling element includes an insulating element and a pair of conductive elements forming a load circuit, the pair of conductive elements being arranged side by side and spaced apart in the insulating element along the height direction, and at least part of the side of the pair of conductive elements facing away from the inner sidewall being exposed outside the insulating element.

[0010] As a further improvement of the present invention, there is a gap between the coupling element and the inner sidewall.

[0011] As a further improvement of the present invention, an adhesive is provided in the gap to bond and fix the coupling element in the mounting groove.

[0012] As a further improvement of the present invention, the track further includes a magnetic element disposed within the accommodating space and located above the coupling element. The end of the coupling element away from the opening cooperates with the frame to form a receiving groove for accommodating the magnetic element. A support portion is formed on the side of the frame away from the coupling element and extending towards the coupling element. The support portion, together with the top surface of the frame and the coupling element, forms the receiving groove.

[0013] As a further improvement of the present invention, along the width direction of the track, the width of the magnetic element is greater than the distance between the bearing portion and the coupling element and less than the distance between the bearing portion and the first snap-fit ​​portion.

[0014] As a further improvement of the present invention, the width of the track is less than or equal to 15 mm.

[0015] As a further improvement of the present invention, the track is one or a combination of linear track and non-linear track.

[0016] A second objective of the present invention is to provide an adapter for use with the aforementioned track.

[0017] To achieve the above objectives, the present invention provides an adapter configured to be mechanically and electrically connected to the aforementioned track.

[0018] A third objective of the present invention is to provide an electrical system including the aforementioned track.

[0019] To achieve the above objectives, the present invention provides an electrical system comprising the aforementioned track.

[0020] The beneficial effects of the present invention are as follows: Compared with the prior art, the track structure of the present invention is simple. By setting a first snap-fit ​​part on the upper and lower surfaces of the mounting groove, and setting a second snap-fit ​​part on the coupling element at the position corresponding to the first snap-fit ​​part, the coupling element is pressed and installed into the mounting groove from the inside of the accommodating space through the cooperation of the first snap-fit ​​part and the second snap-fit ​​part. This improves the installation method of the coupling element, increases installation efficiency, and enables the interconnection of linear and non-linear tracks, thereby improving the docking and versatility of the track.

Detailed Implementation

[0041] 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.

[0042] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0043] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0044] Example 1

[0045] Please see Figure 1-3 The diagram shown is a structural schematic of the track 100 according to the first embodiment of the present invention. The track 100 is a non-linear track 100, used for assembly onto the mounting base 1111 and capable of being connected via an adapter 200 (…). Figure 8 The device is coupled to an electrical device (not shown) to form an electrical system (not shown). The electrical device can slide within the track 100 and its position within the track 100 can be moved as needed.

[0046] Please continue reading Figure 1-3 As shown, the track 100 is annular and made of rigid material, including a main body 11 and a coupling element 12 disposed within the main body 11. Along the height direction of the track 100, that is, along the direction perpendicular to the mounting base 1111, the main body 11 includes a mounting part 111 and a frame 112 disposed away from the mounting part 111 along the height direction. The frame 112 encloses a receiving space 113 with an opening 1131 disposed away from the mounting part 111. The receiving space 113 is used to at least partially receive the adapter 200 so that the adapter 200 can slide within the receiving space 113.

[0047] The mounting part 111 is used for fixed installation on the mounting base 1111, which can be a ceiling or wall, etc. In this embodiment, the mounting part 111 is the side of the frame 112 opposite to the opening 1131. The mounting part 111 is provided with a plurality of mounting holes (not shown). The number of mounting holes is set according to the length of the track 100, and the present invention does not limit this. The plurality of mounting holes are evenly distributed along the length direction of the track 100 for fixing the track 100 to the mounting base 1111.

[0048] The inner wall 1121 of the frame 112 facing the accommodating space 113 is provided with a mounting groove 1122 for snap-fit ​​connection with the coupling element 12. The upper surface 1123 and lower surface 1124 of the mounting groove 1122 extend towards each other to form a pair of first snap-fit ​​portions 114. The coupling element 12 is provided with a pair of second snap-fit ​​portions 123 corresponding to the positions of the first snap-fit ​​portions 114. The coupling element 12 is pressed and installed from the accommodating space 113 into the mounting groove 1122 through the cooperation of the first snap-fit ​​portions 114 and the second snap-fit ​​portions 123. This configuration simplifies the structure of the track 100. By using the cooperation of the first snap-fit ​​portions 114 and the second snap-fit ​​portions 123 to press and install the coupling element 12 from the inside of the frame 112 into the mounting groove 1122, the installation method of the coupling element 12 is improved, and the installation efficiency is increased. Because this installation method avoids inserting or pushing the track 100 into the mounting groove 1122 from the front or back, but instead directly presses it into the mounting groove 1122 from the inside of the frame 112 of the track 100, it can achieve interconnection between linear track 100 and non-linear track 100, improving the docking and versatility of track 100.

[0049] Furthermore, the two first latching portions 114 are arranged facing each other. Each first latching portion 114 includes a first guide slope 1141 and a first limiting portion 1142 arranged at an included angle. The first guide slope 1141 is arranged away from the inner sidewall 1121 relative to the first limiting portion 1142, and the included angle is an acute angle. That is, both first limiting portions 1142 are arranged near the inner sidewall 1121 to limit and fix the coupling element 12. The first guide slope 1141 near the upper surface 1123 extends upward and away from the end of the first limiting portion 1142 away from the upper surface 1123, while the first guide slope 1141 near the lower surface 1124 extends downward and away from the end of the first limiting portion 1142 away from the lower surface 1124. This configuration guides the coupling element 12, facilitating its installation by pressing it from the inside of the frame 112 into the mounting slot 1122.

[0050] Please see Figure 3 and combined Figure 8 As shown, a coupling element 12 is provided, and both it and the track 100 are annular structures. A coupling element 12 is disposed within a mounting groove 1122 of the accommodating space 113 and extends along the length of the track 100. It includes an insulating member 121 and a pair of conductive members 122 forming a load circuit. The conductive members 122 are embedded within the insulating member 121, which has an exposure opening such that at least a portion of the conductive member 122 facing the accommodating space 113 is exposed from the exposure opening to cooperate with the connecting element 23 on the adapter 200 inserted into the accommodating space 113, thereby achieving an electrical connection between the track 100 and the adapter 200.

[0051] The insulating member 121 extends along the height direction of the track 100. Its two ends, positioned opposite each other along the height direction, extend towards the inner wall 1121 to form extension portions 1211. The ends of the two extension portions 1211 extend away from each other to form a pair of second latching portions 123. Each second latching portion 123 includes a second guide slope 1231 and a second limiting portion 1232. The second guide slope 1231 is positioned relative to the second limiting portion 1232 near the inner wall 1121. An angle, specifically an acute angle, is also formed between the second guide slope 1231 and the second limiting portion 1232. In other words, the second limiting portion 1232 on the second latching portion 123 is positioned away from the inner wall 1121. When the coupling element 12 is latched and installed in the mounting groove 1122, the second limiting portion 1232 engages with the first limiting portion 1142 to secure the coupling element 12 within the mounting groove 1122. The inclination direction of the second guide slope 1231 is parallel to that of the first guide slope 1141, so that when the coupling element 12 is pressed and installed into the mounting groove 1122 from the inside of the frame 112, the first guide slope 1141 and the second guide slope 1231 cooperate with each other to guide the second snap-fit ​​part 123 to snap-fit ​​connection with the first snap-fit ​​part 114.

[0052] Furthermore, a pair of conductive elements 122 are arranged side-by-side and spaced apart along the height direction within the insulating element 121. The pair of conductive elements 122 form a power supply circuit on one side of the track 100, i.e., the track 100 is a single-sided power supply track 100. At least part of the side of the pair of conductive elements 122 facing away from the inner sidewall 1121 is exposed outside the insulating element 121, i.e., the side of the conductive elements 122 facing the accommodating space 113 is exposed outside the insulating element 121 to achieve electrical connection with the connecting element 23 on the adapter 200.

[0053] In this embodiment, the insulating component 121 is a plastic extrusion, and the conductive component 122 is a copper sheet embedded in the plastic extrusion. The plastic extrusion and the copper sheet are integrally formed by extrusion process, that is, the coupling element 12 is integrally formed, so as to reduce the processing process of the coupling element 12 and improve the processing efficiency.

[0054] Furthermore, since the second latching portion 123 is formed from the end of the extension portion 1211 of the insulating member 121 in a direction away from each other, there is a gap 124 between the insulating member 121 and the inner sidewall 1121 of the frame 112, that is, there is a gap 124 between the coupling element 12 and the inner sidewall 1121, so as to facilitate heat dissipation of the coupling element 12. In addition, by providing a gap 124 between the coupling element 12 and the inner sidewall 1121, a sufficient distance is provided between the conductive member 122 and the inner sidewall 1121 to avoid the formation of electric arc.

[0055] To improve the stability of the coupling element 12 within the mounting groove 1122, adhesive can be filled into the gap 124 to bond and fix the coupling element 12 within the mounting groove 1122. Preferably, the adhesive can be thermal silicone, which not only improves the installation stability of the coupling element 12 but also facilitates heat dissipation for the coupling element 12.

[0056] It should be noted that in this embodiment, a single coupling element 12 is provided, positioned on one side of the track 100 to form a single-sided power supply track 100. In other embodiments, two coupling elements 12 may also be provided, with each coupling element 12 installed on one side of the track 100. Specifically, the two coupling elements 12 are connected via the first snap-fit ​​part 114 and the second snap-fit ​​part 123 to be snapped into the mounting slots 1122 on both sides from the inside of the frame 112. In this case, the track 100 has a dual electrical circuit, which can address the market trend of independent control for dual-output dimming and color-tuning products. It can also provide independent control for each of the four-wire, three-circuit configurations. The combination of conductive elements 122 can be adjusted according to the actual application's circuit requirements. Alternatively, one of the coupling elements 12 can also be a pair of control circuits to improve the intelligence of the electrical system with the track 100; this invention does not limit this.

[0057] The above-described track 100 structure is suitable for both mechanically connected and magnetically connected tracks 100. When the track 100 is magnetically connected, it further includes a magnetic element 13. The magnetic element 13 and the coupling element 12 are disposed together within the accommodating space 113, with the magnetic element 13 positioned above the coupling element 12 to facilitate connection with the adapter 200 entering the accommodating space 113. Figure 8 ) Perform magnetic connection.

[0058] One end of the coupling element 12 away from the opening 1131 mates with the frame 112 to form a receiving groove 14 for accommodating the magnetic element 13. This arrangement, with the coupling element 12 as part of the receiving groove 14, saves materials, reduces the cost of the track 100, and facilitates the installation of the magnetic element 13.

[0059] In this embodiment, since only one coupling element 12 is provided, the side of the frame 112 away from the coupling element 12 extends towards the coupling element 12 to form a support portion 1125. The support portion 1125, the top surface of the frame 112, and the coupling element 12 together form a receiving groove 14 to receive the magnetic element 13.

[0060] Since the first guide slope 1141 on the first latching portion 114 of the frame 112 extends upward and away from the first limiting portion 1142 away from the upper surface 1123, the first guide slope 1141 also provides space for the installation of the magnetic element 13. When the coupling element 12 is latched into the mounting groove 1122, the coupling element 12 can also serve as part of the receiving groove 14 to limit the magnetic element 13 within the receiving groove 14. That is, along the width direction of the track 100, the width of the magnetic element 13 is greater than the distance between the supporting portion 1125 and the coupling element 12 and less than the distance between the supporting portion 1125 and the first latching portion 114. When assembling the track 100, first fix one end of the magnetic element 13 to the support part 1125, and then press and install the coupling element 12 from the inside of the frame 112. Since the distance between the coupling element 12 and the support part 1125 is less than the width of the magnetic element 13, the coupling element 12, as part of the receiving groove 14, limits and fixes the magnetic element 13 in the receiving groove 14.

[0061] In other embodiments, for example, when the track 100 has two coupling elements 12, the support portion 1125 may not be provided, and the receiving groove 14 may be formed by the two coupling elements 12 and the top surface of the frame 112. When assembling the track 100, one coupling element 12 is first fixed in the mounting groove 1122, then one end of the magnetic element 13 is fixed on the coupling element 12, and then the other coupling element 12 is installed, thereby limiting and fixing the magnetic element 13 in the receiving groove 14.

[0062] Furthermore, the height and width of track 100 are both less than or equal to 15mm, which can reduce the space occupied by track 100.

[0063] Example 2

[0064] Please see Figure 4-5 The diagram shows cross-sectional views of two installation methods for the track 100 according to the second embodiment of the present invention. The track 100 of the second embodiment has a basically the same structure as the track 100 of the first embodiment, except for the arrangement of the mounting part 111. Therefore, only the structural differences will be described here, and the similarities will not be repeated.

[0065] In the second embodiment, the mounting portion 111 of the track 100 extends upward from both ends of the frame 112 and bends towards each other to facilitate mounting the track 100 onto the mounting base 1111. Therefore, the track 100 of the second embodiment can be surface-mounted. Figure 4 ) and embedded installation ( Figure 5When the track 100 is used as an exposed track 100, the mounting base 1111 can be a ceiling or a wall. Fasteners such as screws pass through mounting holes, and the heads of the fasteners ultimately press against both sides of the mounting holes in the ceiling 2111 and lock with the mounting base 1111, thereby fixing the track 100 to the mounting base 1111. When the track 100 is used as an embedded track 100, part of the track 100 can be fixed inside the mounting base 1111 to reduce the space occupied by the track 100.

[0066] Furthermore, in the second embodiment, the width of the track 100 is less than or equal to 15 mm, which can reduce the space occupied by the track 100.

[0067] Example 3

[0068] Please see Figure 6 and combined Figure 3 The image shows a track 100 according to a third embodiment of the present invention. The basic structure of the track 100 in the third embodiment is basically the same as that of the track 100 in the first embodiment, except that the track 100 in the third embodiment is an arc-shaped track 100. Therefore, only the structural differences will be described here, and the similar parts will not be repeated.

[0069] The arc-shaped track 100 includes an arc-shaped main body 11, an arc-shaped magnetic element 13, and an arc-shaped coupling element 12. When assembling the arc-shaped track 100, the arc-shaped magnetic element 13 is first placed in the receiving groove 14, and then the arc-shaped coupling element 12 is pressed and installed from the inside of the frame 112 into the mounting groove 1122. That is, the coupling element 12 is pressed and installed from the receiving space 113 into the mounting groove 1122 through the cooperation of the first snap-fit ​​part 114 and the second snap-fit ​​part 123. In this way, non-linear track 100 can be easily assembled.

[0070] Example 4

[0071] Please see Figure 7 and combined Figure 3 The image shows the track 100 according to the fourth embodiment of the present invention. The basic structure of the track 100 in the fourth embodiment is basically the same as that of the track 100 in the first embodiment, except that the track 100 in the fourth embodiment is a straight track 100 (i.e., a linear track 100). Therefore, only the structural differences will be described here, and the similarities will not be repeated.

[0072] The linear track 100 includes a linear main body 11, a linear magnetic element 13, and a linear coupling element 12. When assembling the linear track 100, the linear magnetic element 13 is first placed in the receiving groove 14, and then the linear coupling element 12 is pressed and installed from the inside of the frame 112 into the mounting groove 1122. That is, the coupling element 12 is pressed and installed from the receiving space 113 into the mounting groove 1122 through the cooperation of the first snap-fit ​​part 114 and the second snap-fit ​​part 123. This improves the assembly method of the linear track 100 and increases its assembly efficiency.

[0073] It should be noted that, in this invention, the magnetic element 13 is fixed by the coupling element 12, which is pressed inward from the inner wall 1121 of the track 100 and fixed in the mounting groove 1122 by the cooperation of the first latching part 114 and the second latching part 123. This installation method improves the conventional assembly method of the track 100, enabling at least two tracks 100 to be cascaded according to user needs, that is, enabling the splicing combination of linear track 100 and non-linear track 100. Moreover, in the splicing of linear track 100 and non-linear track 100, the coupling element 12 can be directly shared, without the need for a conductive connector to achieve electrical connection between the linear track 100 and non-linear track 100, thereby reducing the number of electrical connection contacts and improving the stability and safety of the electrical connection of the cascaded track 100.

[0074] Please see Figure 8-15 and combined Figure 1-7 As shown, the present invention provides an adapter 200 configured to be mechanically and electrically connected to the aforementioned track 100, for coupling electrical equipment to the track 100.

[0075] The adapter 200 includes a housing 21, a magnetic attractor 22 at least partially housed within the housing 21, a power receiving element 23, and a glass bead assembly 25. The housing 21 includes a top wall 2111 facing the track 100, a bottom wall opposite the top wall 2111, and a first side wall 2112 and a second side wall 2113 connected to the top wall 2111 and arranged opposite each other in the width direction. The magnetic attractor 22 is disposed near the top wall 2111 and passes through the top wall 2111 to magnetically connect with the magnetic attractor of the track 100. The power receiving element 23 and the glass bead assembly 25 are respectively disposed on the first side wall 2112 and the second side wall 2113, and are at least partially exposed on the first side wall 2112 and the second side wall 2113, so that one side of the adapter 200 can draw power from the track 100 from the side, and the other side is designed to prevent detachment through the glass bead assembly 25, thereby improving the stability of the connection between the adapter 200 and the track 100.

[0076] In this embodiment, the housing 21 includes a cover 212 and a groove 211. The groove 211 is disposed above the cover 212. The top wall 2111 of the housing 21 is the top wall 2111 of the groove 211. The first side wall 2112 and the second side wall 2113 of the housing 21 are the first side wall 2112 and the second side wall 2113 of the groove 211. The bottom wall of the housing 21 is the cover 212.

[0077] The groove 211 and the cover 212 are snap-fitted together. The cover 212 includes a base plate 2121 and a first fastening portion 2122 extending from the base plate 2121 toward the groove 211. A second fastening portion 2114 is provided on the side wall of the groove 211 corresponding to the position of the first fastening portion 2122. The groove 211 and the cover 212 are snap-fitted together by the first fastening portion 2122 and the second fastening portion 2114. In this embodiment, the first fastening portion 2122 is a hook, and the second fastening portion 2114 is a latch. The hook and the latch cooperate to snap-fit ​​the groove 211 and the cover 212 together. In other embodiments, the first fastening portion 2122 may also be a latch, and the second fastening portion 2114 may be a hook, or the first fastening portion 2122 and the second fastening portion 2114 may be in other forms.

[0078] A receiving space 213 is formed between the cover 212 and the groove 211. The magnetic attractor 22, the electrical contact element 23 and the glass bead assembly 25 are sequentially received in the receiving space 213 and at least partially exposed outside the housing 21 to achieve a matching connection with the track 100.

[0079] A magnetic suction element 22 is disposed at the end of the groove 211 opposite to the cover 212, i.e., the magnetic suction element 22 is disposed near the top wall 2111 of the groove 211. The magnetic suction element 22 includes a first part 221 and a second part 222 connected together, wherein the cross-sectional area of ​​the first part 221 is smaller than the cross-sectional area of ​​the second part 222. The top wall 2111 of the groove 2111 has an opening slot 2115, the cross-sectional area of ​​which is larger than the cross-sectional area of ​​the first part 221 and smaller than the cross-sectional area of ​​the second part 222. This arrangement allows the first part 221 to pass through the opening slot 2115 of the groove 2111 and magnetically connect with the track 100 when the magnetic suction element 22 is placed upside down into the groove 2111, while the second part 222 is confined within the receiving space 213 of the groove 211 by the opening slot 2115.

[0080] Furthermore, to improve the stability of the magnetic chuck 22 when placed upside down in the receiving space 213, a protrusion 2116 is provided on the side of the groove 211 facing the receiving space 213. That is, the protrusion 2116 is provided on the side wall of the groove 211 facing the receiving space 213, and the protrusion 2116 limits and fixes the magnetic chuck 22 in the housing 21. Preferably, the distance between the protrusion 2116 and the opening slot 2115 is similar to the height of the second part 222 of the magnetic chuck 22, so that when the first part 221 of the magnetic chuck 22 passes through the opening slot 2115 of the groove 211 and magnetically connects with the track 100, the second part 222 is limited and fixed between the protrusion 2116 and the opening slot 2115.

[0081] It should be noted that, in the case of magnetic element 13 and magnetic attractor 22, one can be a permanent magnet and the other can be an iron sheet, and the permanent magnet and the iron sheet can be magnetically attracted together. Alternatively, both magnetic element 13 and magnetic attractor 22 can be permanent magnets, and the opposite magnetic poles of the two permanent magnets can be magnetically attracted together. In this embodiment, magnetic element 13 is an iron sheet, magnetic attractor 22 is a permanent magnet, and the shape of magnetic element 13 matches the shape of track 100. When track 100 is a circular track 100, magnetic element 13 can be a single circular iron sheet or composed of multiple arc-shaped iron sheets spliced ​​together. When track 100 is an arc-shaped track 100, magnetic element 13 can be a single arc-shaped iron sheet or composed of multiple arc-shaped iron sheets spliced ​​together. When track 100 is a straight track 100, magnetic element 13 is a straight iron sheet.

[0082] An extension arm 2123 is provided on the side of the cover 212 facing the receiving space 213, and the extension arm 2123 is disposed on both sides adjacent to the first latching part 114. A power receiving element 23 is disposed between the extension arm 2123 and the magnetic suction member 22, so as to be limited and fixed by the extension arm 2123 and the magnetic suction member 22.

[0083] The electrical connection element 23 includes an insulating bracket 231, a first electrical connector 232 and a second electrical connector 233 fixedly connected to the insulating bracket 231. The first electrical connector 232 is electrically connected to the second electrical connector 233, and is also electrically connected to the track 100 and the electrical equipment, respectively, configured to electrically connect the track 100 to the electrical equipment.

[0084] Specifically, the first electrical connector 232 includes a pair of metal pieces forming a load circuit, which are offset along the height direction at different heights of the first sidewall 2112 of the adapter 200. The first sidewall 2112 of the groove 211 corresponds to the inner sidewall 1121 of the track 100 where the coupling element 12 is located. An opening 2117 offset along the height direction is provided on the first sidewall 2112, so that the pair of metal pieces can extend out of the opening 2117 and be electrically connected to a pair of conductive elements 122 in the coupling element 12, thereby realizing power extraction from one side of the track 100 and the adapter 200. Preferably, the metal pieces are elastic copper sheets to improve the performance of the electrical connection. In other embodiments, the metal pieces can also be made of other elastic metal materials, and the scope of the present invention is not limited in this respect.

[0085] Furthermore, the insulating bracket 231 is integrally formed with the first electrical connector 232. That is, the metal part and the insulating bracket 231 are integrally injection molded to save the number of parts and reduce the assembly difficulty.

[0086] The second electrical connector 233 consists of a pair of power lines, which are soldered onto a pair of metal parts and used for electrical connection with electrical equipment. A through hole 2124 is provided on the cover 212 at the position corresponding to the power lines, and the end of the pair of power lines away from the metal parts passes through the through hole 2124 to connect electrically with the electrical equipment.

[0087] Furthermore, the adapter 200 also includes an elastic element 24 disposed between the insulating support 231 and the second sidewall 2113, configured to keep the first electrical connector 232 at least partially exposed outside the first sidewall 2112. That is, the elastic element 24 is in a slightly compressed state. When the adapter 200 is installed onto the track 100 from the opening 1131, the frame 112 of the track 100 exerts a certain force on the first electrical connector 232, causing the first electrical connector 232 to be pressed towards the elastic element 24, at which point the elastic element 24 is further compressed. When the adapter 200 has entered the receiving space 113 of the track 100, the elastic element 24 recovers its deformation under its own elastic force, thereby pushing the first electrical connector 232 away from the elastic element 24, thus keeping the first electrical connector 232 at least partially exposed outside the first sidewall 2112, thereby improving the stability of the electrical connection between the first electrical connector 232 and the coupling element 12 of the track 100.

[0088] Furthermore, the glass bead assembly 25 is disposed on the second side wall 2113 of the housing 21, which is opposite to the first side wall 2112. That is, the power receiving element 23 and the glass bead assembly 25 are disposed on two opposite side walls of the housing 21 to fully utilize the space of the adapter 200, allowing one side of the housing 21 to be used for side power extraction, and the other side for anti-detachment design, thus improving the structural compactness and reducing the size of the adapter 200. By setting the glass bead assembly 25, the safety hazard caused by unstable magnetic connection leading to the detachment of the lamp body can be avoided, improving the stability and safety of the track 100 connection.

[0089] The glass bead assembly 25 is positioned close to the cover 212 relative to the connecting element 23 and is fixed to the housing 21 through the cover 212 and the groove 211. Since the connecting element 23 is limited and fixed between the extension arm 2123 of the cover 212 and the magnetic element 13, there is a certain space between the connecting element 23 and the bottom plate 2121 of the cover 212. By positioning the glass bead assembly 25 close to the cover 212, the space of the adapter 200 can be utilized reasonably, and the volume of the adapter 200 can be reduced.

[0090] The glass bead assembly 25 includes a circular glass bead 251 and a cylindrical arm 253, and an annular baffle 252 extending outward from the cylindrical arm 253, disposed between the circular glass bead 251 and the cylindrical arm 253. A lug 2125 extends towards the groove 211 and is provided on the base plate 2121 opposite to the first fastening part 2122. A first mounting hole 2126 is provided on the lug 2125, and a second mounting hole 2118 is provided on the groove 211 corresponding to the position of the first mounting hole 2126. The diameter of the annular baffle 252 is larger than the diameter of the first mounting hole 2126 but equal to or smaller than the diameter of the second mounting hole 2118. When the glass bead assembly 25 is installed on the housing 21, the cylindrical arm 253 passes sequentially through the second mounting hole 2118 and the first mounting hole 2126 and is received within the receiving space 213 of the housing 21. Since the diameter of the first mounting hole 2126 is larger than the diameter of the annular baffle 252, the annular baffle 252 is blocked by the first mounting hole 2126, so that it is fixed in the second mounting hole 2118, thereby limiting and fixing the circular glass bead 251 connected to the annular baffle 252 to the outside of the groove 211, so as to achieve contact with the track 100.

[0091] When assembling the adapter 200, the magnetic clasp 22 is first inverted and placed inside the receiving space 213. The first part 221 of the magnetic clasp 22 protrudes from the top wall 2111 of the groove 211, while the second part 222 is fixed between the protrusion 2116 and the opening slot 2115. Then, the connecting element 23 is placed inside the receiving space 213, with the first connecting element 23 protruding from the opening 2117 of the groove 211 onto the first side wall 2112. The elastic element 24 is then placed between the connecting element 23 and the housing 21. Afterward, the cover 212 is snapped and fixed to the groove 211, while the cover 212 also fixes the connecting element 23 between the magnetic clasp and the extension arm 2123. The second connecting element 23 passes through the through hole 2124 on the cover 212 for electrical connection to the electrical equipment. Finally, the glass bead assembly 25 is pressed in from the outside of the housing 21. That is, the cylindrical arm 253 is fixed in the receiving space 213 by passing through the second mounting hole 2118 and the first mounting hole 2126 in sequence, while the annular baffle 252 is blocked outside by the first mounting hole 2126 and then fixed in the second mounting hole 2118. This ensures that the glass bead assembly 25 can be exposed outside the housing 21 to achieve an anti-detachment connection with the track 100, improve the stability of the connection between the adapter 200 and the track 100, and enhance the user experience.

[0092] This invention provides an electrical system comprising electrical equipment, the aforementioned rail 100, and an adapter 200. The electrical equipment is coupled to the rail 100 via the adapter 200. The electrical equipment includes power-consuming devices and / or power supply devices. The power supply device can be a drive power source used to convert the voltage of the rail 100 to a suitable operating voltage, such as converting 220V AC power to the required DC power. The power-consuming devices can be lighting fixtures, sensor modules, monitoring equipment, or other devices to provide corresponding functions.

[0093] In summary, the track 100 of the present invention has a simple structure. By providing a first latching part 114 on the upper surface 1123 and the lower surface 1124 of the mounting groove 1122, and providing a second latching part 123 on the coupling element 12 at the position corresponding to the first latching part 114, the coupling element 12 is pressed and installed into the mounting groove 1122 from the inside of the accommodating space 113 through the cooperation of the first latching part 114 and the second latching part 123. This improves the installation method of the coupling element 12, increases installation efficiency, and enables the interconnection of linear track 100 and non-linear track 100, thereby improving the docking and versatility of the track 100.
