[0002] A track light is a lighting system installed on a track, usually including a track and a lamp body. The track is fixedly installed on a mounting surface such as a wall or a ceiling, or is suspended by a suspension wire to form a track system, and then the lamp body is installed on the track. A conductive metal strip is provided inside the track and is supplied with voltage. At the same time, a conductive copper sheet is provided at the joint of the lamp body. When the conductive copper sheet on the lamp body contacts the conductive metal strip inside the track, the lamp body can be powered on and lit. Since the lamp body can be set at any position on the track, the lamp body can be moved and adjusted according to the installation needs.

[0027] The connector, conductive track system and lighting system proposed by the present invention are further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] A connector in a preferred embodiment of the present application is as Figure 1 , Figure 2 shown. The connector 1 includes a main body portion 101 and two connection joints 102 provided at both ends of the main body portion 101. The connection joint 102 is as Figure 4 shown and includes a mechanical connection portion 1022 and an electrical connection portion 1023. By connecting two conductive tracks 2 through the connector 1, a conductive track system of a preferred embodiment can be formed, as Figure 8 , Figure 9As shown in the figure. The mechanical connection part 1022 is connected to the end of the conductive track 2, and multiple conductive tracks 2 are connected to form a whole. A conductive strip 202 extending along the length direction of the conductive track 2 is laid on the conductive track 2, and the conductive strip 202 and the track body 201 are insulated from each other by an insulating strip 203. When the conductive track 2 is connected to the connector 1, the electrical connection parts 1023 of the conductive strips 202 are electrically connected. Inside one connector 1, the electrical connection parts 1023 of each connection joint 102 are conductively connected to each other, so that the conductive strips 202 on the connected conductive tracks 2 are electrically connected.

[0029] In this embodiment, the main body part 101 is columnar and is divided into two parts, an upper cover 1011 and a lower cover 1012, which are connected by screws. A connection joint 102 is provided at each end of the main body part 101, and the connection joint 102 is rotatably connected to the main body part 101. In this way, when the conductive track 2 is connected to the connection joint 102, it can rotate relative to the main body part 101 together with the connection joint 102, and the rotation axis is consistent with the extension direction of the conductive track 2, so as to realize the angle adjustment of the conductive track 2. In this embodiment, the connection joints 102 are respectively arranged at both ends of the main body part 101, and the connected conductive track system is linear. In other preferred embodiments, the main body part 101 can also be L-shaped or arc-shaped, and a conductive track system with a bend is formed after connection. The number of connection joints 102 attached to the main body part 101 can also be more than 2. At this time, the main body part 101 can be in a cross shape or other radial shapes, and multiple connection joints 102 are arranged at the ends to form a more complex track system. The present application does not limit the specific form of the main body part 101.

[0030] The connection joint 102 is as Figure 4 shown, and includes a cover plate 1021 covering the end of the conductive track 2, as well as a mechanical connection part 1022 and an electrical connection part 1023 arranged on the side of the cover plate 1021 facing away from the main body part 101. The mechanical connection part 1022 is a plug plate protruding from the cover plate 1021 towards the side away from the main body part 101, and the conductive track 2 is provided with a slot 2013 that cooperates with it. During connection, the plug plate of the mechanical connection part 1022 is inserted into the slot 2013. In order to fix the conductive track 2 to prevent it from detaching from the connector 1, a first through hole 10221 is also provided on the plug plate, and a first screw hole 2014 is provided on the conductive track 2. A screw is used as a connecting piece to connect and fix the two. In this embodiment, the plug plate serving as the mechanical connection part 1022 and the cover plate 1021 are integrally formed, as Figure 5 shown. In other preferred embodiments, the mechanical connection part 1022 can also be a separate connecting piece that is connected to the conductive track 2 and then connected to the cover plate 1021. In addition, the mechanical connection part 1022 can also be a connecting structure such as a buckle or a hanging piece, and the present application does not limit this.

[0031] The electrical connection part 1023 includes a terminal box 10231 and a conductive contact 10232. The terminal box 10231 is arranged on the side of the cover plate 1021 facing away from the main body part 101 and protrudes from the cover plate 1021. As Figure 6 shown, one end of the conductive contact 10232 protrudes from the surface of the terminal box 10231, and the other end is arranged inside the terminal box 10231 and connected to the wire 10233. As Figure 5 shown, a wire passing hole 10212 is also arranged on the cover plate 1021. The wire 10233 passes through the wire passing hole 10212 and enters the main body part 101, and is connected to the wires 10233 of other connection joints 102 inside the main body part 101 to realize electrical conduction between the connection joints 102. A second screw hole 10234 is also arranged on the terminal box 10231, and a second through hole 10211 is arranged on the cover plate 1021. The terminal box 10231 is fixedly connected to the cover plate 1021 by screws. In this embodiment, the mechanical connection part 1022 and the electrical connection part 1023 are arranged at intervals in a stacked manner. The insertion plate serving as the mechanical connection part 1022 is parallel to the surface of the terminal box 10231 close to the mechanical connection part 1022, and the conductive contact 10232 is arranged on this surface, and the conductive contact 10232 is within the projection of the mechanical connection part 1022. In such a stacked arrangement, when connecting, the mechanical connection part 1022 and the electrical connection part 1023 are inserted into the end of the conductive track 2 together, which can improve the connection stability. And the conductive contact 10232 protrudes towards the mechanical connection part 1022 and is under its projection, which can prevent the hand from touching the conductive contact 10232 during operation, thus ensuring safety.

[0032] In order to realize the rotational connection between the connection joint 102 and the main body part 101, the connection joint 102 and the main body part 101 are connected by a rotating shaft 103. As Figure 7 shown, the rotating shaft 103 includes a first part 1031 and a second part 1032 that can rotate relative to each other. As Figure 2 、 Figure 3 shown, a first shaft seat 1013 is arranged on the main body part 101. And on the side of the cover plate 1021 of the connection joint 102 facing the main body part 101, a second shaft seat 1024 is arranged, and the second shaft seat 1024 is integrally formed with the cover plate 1021. The first part 1031 of the rotating shaft 103 is fixedly connected after being fitted and installed with the first shaft seat 1013, and the second part 1032 of the rotating shaft 103 is fixedly connected to the second shaft seat.

[0033] In this embodiment, the main body part 101 of the connector 1 includes an upper cover 1011 and a lower cover 1012, and the two are combined to form the outer contour of the main body part. In addition to playing the role of connecting the conductive track 2, the connector is also as Figure 8 、 Figure 9Installation components of a conductive track system. The conductive track 2 is installed on an installation base through a connector 1. Therefore, the main body 101 further includes an installation part, which in this embodiment is an installation hole 1013 provided on the upper cover 1011. It is hung on the roof or ceiling through a suspension wire assembly 3 to form a hung conductive track system. In addition, the plane on the upper part of the upper cover 1011 can also be used as the installation part, and the connector 1 can be directly installed on the installation bases such as the roof or wall surface by means of pasting, screws, etc. In addition, the form of the installation part can be more diverse, such as snap connectors, embedded components, magnetic components, etc., and the present application does not limit this. When the main body 101 is fixedly connected to the installation base, when the conductive track 2 rotates relative to the main body 101 with the connection joint 102, the angle of the coverable conductive track 2 relative to the installation base can be adjusted, so as to achieve a more flexible track setting.

[0034] In the preferred embodiment of the conductive track system of the present application, the conductive track 2 is as Figure 10 , Figure 11 shown, including a track body 201 extending in one direction. The track body 201 includes a bottom plate 2011 and side walls 2012 provided on both sides of the bottom plate 2011. In this embodiment, the conductive strip 202 is provided on the inner side of the bottom plate 2011 through an insulating strip 203, and a slot 2013 for cooperating with the mechanical connection part 1022 of the connector 1 is provided on the outer side of the bottom plate 2012. The above structure is basically similar to a conventional square fixed track. The difference is that in the conductive track system proposed in the present application, the conductive track 2 can rotate around its extension direction as the axis. Therefore, an arc outer contour 2014 is also provided on the outside of the square track. Since there is an opening on one side of the conductive track 2 for the insertion of the lamp connector, the overall outer contour does not form a closed circle, but at least part of the outer contour of the track body 201 in the cross-section perpendicular to its extension direction is an arc. In order to maintain the overall appearance consistency of the conductive track system, at least part of the outer contour of the main body 101 of the connector 1 in the cross-section perpendicular to the axis of the rotating shaft 103 is an arc, and the shape of the cover plate 1021 is the same as the cross-sectional shape of the main body 101.

[0035] The conductive track system of this embodiment can be used in various lighting scenarios. Cooperating with corresponding track lamps, it can form a lighting system. The conductive track system is fixedly installed on installation bases such as the roof or wall surface. The track lamps (not shown) are installed on the conductive track 2 and are electrically connected to the conductive strip 202, so as to draw power from the conductive track 2 to achieve the lighting function.

[0036] The above description of the preferred embodiments of the present invention is for the purpose of illustration and description, and is not intended to exhaust or limit the present invention to the specific forms disclosed. Obviously, many modifications and changes may be made, and these modifications and changes may be obvious to those skilled in the art and should be included within the scope of the present invention defined by the appended claims.
