Description

Technical Field

[0001] This invention relates to the field of lighting fixtures, and in particular to a conductive connection mechanism for track lights and a track light. Background Technology

[0002] The conductive contact components of existing LED track lights mostly adopt a design where ordinary spring contacts are bonded to a flat copper strip. Over long-term use, dust easily accumulates on the surface of the copper strip and an oxide layer forms, which leads to a continuous increase in contact resistance, causing malfunctions such as unstable lighting and power outages. This makes it difficult to meet the stable conductivity requirements of track lights for long-term, high-frequency sliding use. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a conductive connection mechanism for track lights.

[0005] According to a first aspect of the present invention, a track light conductive connection mechanism includes a slide rail body and a sliding box. The slide rail body is provided with a slide rail groove, and a conductive copper busbar is provided on the side of the slide rail groove. The sliding box is slidably disposed in the slide rail groove, and a rotating member is rotatably disposed in the sliding box. The rotating member is provided with a conductive piece corresponding to the conductive copper busbar. The conductive copper busbar includes a first elastic clamping piece, a second elastic clamping piece, and a connecting portion extending along the length direction of the conductive copper busbar. The first elastic clamping piece and the second elastic clamping piece are distributed opposite to each other. The connecting portion connects the first elastic clamping piece and the second elastic clamping piece, and a clamping space corresponding to the conductive piece is formed between the first elastic clamping piece and the second elastic clamping piece. When the rotating member rotates, the conductive piece can rotate with the rotating member and be inserted into the clamping space. The first elastic clamping piece is provided with a cleaning portion and a contact portion. When the conductive piece is inserted into the clamping space, the cleaning portion can scrape the surface of the conductive piece and form a cleaning area.

[0007] According to some embodiments of the present invention, the cleaning part is a protruding structure that protrudes toward the clamping space, and the conductive sheet is provided with a groove corresponding to the cleaning part.

[0008] According to some embodiments of the present invention, the end of the first elastic clamping piece connected to the connecting portion is designated as the connecting end. The first elastic clamping piece is provided with a horizontal section on the side of the protruding structure near the connecting end. The horizontal section is the contact portion.

When the conductive piece is inserted to the set distance, the cleaning portion can fall into the groove, and the contact portion abuts against the upper surface of the conductive piece.

[0009] According to some embodiments of the present invention, the conductive copper busbar is formed by bending a conductive metal plate. The first elastic clamping piece and the second elastic clamping piece are distributed in the vertical direction. The connecting portion is located on the side of the conductive copper busbar and connects the first elastic clamping piece and the second elastic clamping piece respectively. The first elastic clamping piece has an upper convex section, an upper horizontal section, a lower convex section, and an upper curved section in sequence in the direction away from the connecting end. The upper convex section is used to form the clamping space and can generate an elastic restoring force. The contact portion is formed at the lower end face of the upper horizontal section, and the cleaning portion is formed at the lower end of the lower convex section. The second elastic clamping piece has a lower horizontal section and a lower curved section in sequence in the direction away from the connecting end. The lower horizontal section is used to contact the lower end face of the conductive piece. The lower curved section and the upper curved section form a trumpet-shaped opening structure on one side of the clamping space.

[0010] According to some embodiments of the present invention, one side of the conductive copper busbar for the conductive sheet is designated as the insertion side, and the other side of the conductive copper busbar is designated as the connection side. The first elastic clamping piece is provided with a plurality of first breaking grooves at intervals along the length direction of the conductive copper busbar, and the second elastic clamping piece is provided with a plurality of second breaking grooves at intervals along the length direction of the conductive copper busbar. Both the first breaking grooves and the second breaking grooves extend from the insertion side toward the connection side, and the first breaking grooves and the second breaking grooves are staggered in the length direction of the conductive copper busbar.

[0011] According to some embodiments of the present invention, the second elastic clamping piece is formed by stamping to form a plurality of reinforcing ribs, the reinforcing ribs being located between adjacent second breaking grooves.

[0012] According to some embodiments of the present invention, the reinforcing rib is formed by stamping a groove on the second elastic clamping piece, and the depth h of the second breaking groove extending from the insertion side toward the connection side is less than the distance d from the reinforcing rib to the insertion side.

[0013] According to some embodiments of the present invention, the first elastic clamping piece is provided with a plurality of auxiliary through holes penetrating the first elastic clamping piece in the vertical direction, the auxiliary through holes being located between adjacent first breaking grooves, and the auxiliary through holes and the second breaking grooves being staggered in the length direction of the conductive copper busbar.

[0014] According to some embodiments of the present invention, the end of the conductive sheet corresponding to the conductive copper busbar is an arc-shaped structure.

The rotation direction of the conductive sheet is set to clockwise. The center A of the arc-shaped structure is located on the counterclockwise side of the line connecting any point of the arc-shaped structure and the rotation center of the rotating member.

[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] The following is for reference. Figures 1 to 9 The present invention describes a track light conductive connection mechanism and a track light according to an embodiment of the present invention.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the track light conductive connection mechanism according to an embodiment of the present invention includes a slide rail body and a sliding box 200. The slide rail body is provided with a slide rail groove, and a conductive copper busbar 100 is provided on the side of the slide rail groove. The sliding box 200 is slidably disposed in the slide rail groove, and a rotating member 210 is rotatably disposed in the sliding box 200. The rotating member 210 is provided with a conductive piece 220 corresponding to the conductive copper busbar 100. The conductive copper busbar 100 includes a first elastic clamping piece 110, a second elastic clamping piece 120, and a connecting portion 130 extending along the length direction of the conductive copper busbar 100. The first elastic clamping piece 110 and the second elastic clamping piece 120 are distributed opposite to each other and connected... The connector 130 connects the first elastic clamping piece 110 and the second elastic clamping piece 120. A clamping space corresponding to the conductive piece 220 is formed between the first elastic clamping piece 110 and the second elastic clamping piece 120. When the rotating member 210 rotates, the conductive piece 220 can rotate with the rotating member 210 and be inserted into the clamping space. The first elastic clamping piece 110 is provided with a cleaning part 111 and a contact part 112. When the conductive piece 220 is inserted into the clamping space, the cleaning part 111 can scrape the surface of the conductive piece 220 and form a cleaning area. When the conductive piece 220 is inserted to a set distance, the contact part 112 abuts against the cleaning area to form an electrical connection.

[0025] By scraping the surface of the conductive sheet 220 with the cleaning part 111, dust, oxide layer and other substances on the conductive sheet 220 are removed, forming a clean area for contact and mating with the contact part 112, thereby improving the electrical connection effect between the conductive sheet 220 and the conductive copper busbar 100.

[0026] like Figure 4 , Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the cleaning part 111 is a protruding structure that protrudes toward the clamping space, and the conductive sheet 220 is provided with a groove 221 corresponding to the cleaning part 111. When the conductive sheet 220 is inserted to a set distance, the cleaning part 111 can fall into the groove 221 so that the contact part 112 can fit and abut against the cleaning area.

[0027] In some embodiments of the present invention, when the set distance guides the conductive sheet 220 to reach the set power-on position, the insertion depth of the conductive sheet 220 relative to the conductive copper busbar 100 usually refers to the limit position when the rotating member 210 is rotated out.

[0028] In some embodiments of the present invention, when the conductive sheet 220 is inserted to a set distance, the cleaning part 111 can fall into the groove 221, which can generate a snapping vibration sensation, making it convenient for the user to judge whether the conductive sheet 220 is inserted into the designed power connection position. After the cleaning part 111 falls into the groove 221, it can reduce the relative movement between the conductive sheet 220 and the conductive copper busbar 100, and improve the stability of the power connection.

[0029] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the end of the first elastic clamping piece 110 connected to the connecting portion 130 is designated as the connecting end. The first elastic clamping piece 110 has a horizontal portion on the side of the protruding structure near the connecting end, which is the contact portion 112. During the insertion of the conductive piece 220 into the clamping space, the cleaning portion 111 can scrape the upper surface of the conductive piece 220 to form a cleaning area. When the conductive piece 220 is inserted to a set distance, the cleaning portion 111 can fall into the groove 221, and the lower end face of the contact portion 112 abuts against the upper surface (cleaning area) of the conductive piece 220, thereby improving the conductivity between the contact portion 112 and the conductive piece 220.

[0030] It is understood that in some embodiments of the present invention, the contact portion 112 may also be an inclined section, and the upper end surface (cleaning area) of the conductive sheet 220 may be set as a corresponding inclined surface.

[0031] like Figure 7 and Figure 8 As shown, in some embodiments of the present invention, the conductive copper busbar 100 is formed by bending a conductive metal plate. A first elastic clamping piece 110 and a second elastic clamping piece 120 are distributed along the vertical direction. A connecting portion 130 is located on the side of the conductive copper busbar 100 and connects the first elastic clamping piece 110 and the second elastic clamping piece 120 respectively. The first elastic clamping piece 110, moving away from the connecting end, consists of an upwardly convex section 110a, an upper horizontal section 110b, a downwardly convex section 110c, and an upwardly curved section 110d. The upper horizontal section 110b forms a contact portion 112 at its lower end face, and the lower end of the lower convex section 110c forms a cleaning portion 111. The second elastic clamping piece 120 has a lower horizontal section 120a and a lower curved section 120b in sequence in the direction away from the connection end. The lower horizontal section 120a is used to contact the lower end face of the conductive piece 220. The lower curved section 120b and the upper curved section 110d form a funnel-shaped opening structure on one side of the clamping space to facilitate the insertion of the conductive piece 220.

[0032] It is understood that in some embodiments of the present invention, the first elastic clamping piece 110 and the second elastic clamping piece 120 may be independent elongated pieces, which are connected by a connecting part 130 such as a screw or rivet to form a conductive copper busbar 100.

[0033] like Figure 4As shown, in some embodiments of the present invention, the end of the conductive sheet 220 corresponding to the conductive copper busbar 100 is an arc-shaped structure 220a. When the conductive sheet 220 is rotated and inserted into the conductive copper busbar 100, the arc-shaped structure 220a is inserted into the clamping space first. The radius r of the arc-shaped structure 220a is smaller than the radius R of the arc-shaped structure 220a when it rotates with the rotation center of the rotating member 210. The rotation direction of the conductive sheet 220 is set to the clockwise direction. The center A of the arc-shaped structure 220a is located on the counterclockwise side of the line n connecting any point of the arc-shaped structure 220a and the rotation center of the rotating member 210.

[0034] Figure 4 The diagram shows the positional change trend of the conductive copper busbar 100 relative to the rotating component 210 when the rotating component 210 rotates. By setting an arc-shaped structure 220a and making the arc-shaped structure 220a contact the opening structure of the clamping space first, the contact area between the conductive sheet 220 and the conductive copper busbar 100 can be increased quickly, and the transition is smoother and more stable than that of the flat structure.

[0035] like Figure 4 As shown, the radius r of the arc structure 220a is smaller than the radius R when the arc structure 220a rotates with the rotation center of the rotating member 210. The rotation direction of the conductive sheet 220 is set to clockwise. The center A of the arc structure 220a is located on the counterclockwise side of the line n connecting any point of the arc structure 220a and the rotation center of the rotating member 210. That is, the center A of the arc structure 220a is offset in the opposite direction of the rotation direction (offset to the right). This makes the insertion direction of the arc structure 220a coincide with its radial direction or have a small angle when it is inserted into the clamping space. That is, it reduces the angular offset between the insertion direction of the arc structure 220a and its radial direction. This allows the contact area between the conductive sheet 220 and the conductive copper busbar 100 to expand rapidly and smoothly, and the force is more balanced, making the insertion process smooth.

[0036] like Figure 5 and Figure 6As shown, in some embodiments of the present invention, one side of the conductive copper busbar 100 for the conductive sheet 220 is designated as the insertion side, and the other side of the conductive copper busbar 100 is designated as the connection side. A first elastic clamping piece 110 is provided with a plurality of first breaking grooves 113 spaced apart along the length direction of the conductive copper busbar 100, and a second elastic clamping piece 120 is provided with a plurality of second breaking grooves 121 spaced apart along the length direction of the conductive copper busbar 100. Both the first breaking grooves 113 and the second breaking grooves 121 extend from the insertion side toward the connection side, and the first breaking groove 113 and the second breaking groove 220 are spaced apart. The two interrupted grooves 121 are staggered along the length of the conductive copper busbar 100. The first interrupted groove 113 and the second interrupted groove 121 enable the conductive copper busbar 100 to achieve good elastic deformation performance at each length position, thereby improving the clamping effect on the conductive sheet 220. At the same time, the staggered distribution of the first interrupted groove 113 and the second interrupted groove 121 along the length of the conductive copper busbar 100 avoids the situation where the first interrupted groove 113 and the second interrupted groove 121 are aligned, thereby reducing the occurrence of the conductive sheet 220 being hollowed out at both the top and bottom.

[0037] Specifically, since the conductive copper busbar 100 is usually set to be relatively long, if the interruption groove is not set, problems such as difficulty in insertion and poor clamping effect will occur in the middle section of the conductive copper busbar 100. By setting the interruption groove, the first elastic clamping piece 110 and the second elastic clamping piece 120 can be divided into multiple segments along the length direction to ensure the elastic deformation performance at each position.

[0038] like Figure 6 As shown, in some embodiments of the present invention, the second elastic clamping piece 120 is formed by stamping to form a plurality of reinforcing ribs 122, which are located between adjacent second break grooves 121 to improve the structural strength of the second elastic clamping piece 120.

[0039] Specifically, in some embodiments of the present invention, the first elastic clamping piece 110 is bent and provided with an elastic deformation structure, and the structural strength of the second elastic clamping piece 120 is enhanced by the reinforcing rib 122. This can be combined with the first elastic clamping piece 110, which has a large deformation performance, to improve the stability of clamping the conductive sheet 220.

[0040] like Figure 6 As shown, in some embodiments of the present invention, the reinforcing rib 122 is formed by stamping a groove on the second elastic clamping piece 120, and the depth h of the second breaking groove 121 extending from the insertion side toward the connection side is less than the distance d from the reinforcing rib 122 to the insertion side, thereby reducing the distance between the second breaking groove 121 and the stamped groove of the reinforcing rib 122, and reducing the occurrence of breakage or bending between the second breaking groove 121 and the reinforcing rib 122.

[0041] like Figure 5As shown, in some embodiments of the present invention, the first elastic clamping piece 110 is provided with a plurality of auxiliary through holes 114 extending through the first elastic clamping piece 110 in the vertical direction. The auxiliary through holes 114 are located between adjacent first interruption grooves 113, and the auxiliary through holes 114 and the second interruption grooves 121 are staggered in the length direction of the conductive copper busbar 100 to further improve the elastic deformation performance of the middle position of the first elastic clamping piece 110. At the same time, the auxiliary through holes 114 do not connect to the insertion side of the conductive piece 220, that is, they do not form an opening on the insertion side of the conductive piece 220, thus ensuring the overall structural strength of the first elastic clamping piece 110.

[0042] like Figure 3 As shown, in some embodiments of the present invention, a power module 230 is disposed inside the sliding box 200. The power module 230 is provided with a contact piece 231 that abuts against the contact end 222 of the conductive sheet 220. When the rotating member 210 rotates to separate from the conductive copper busbar 100, the conductive sheet 220 is screwed into the area overlapping with the contact piece 231. There is a gap between the conductive sheet 220 and the contact piece 231. The sliding box 200 is provided with a partition groove 201 that can accommodate the conductive sheet 220 being screwed into or separate the conductive sheet 220 and the contact piece 231, so as to improve the isolation effect between the conductive sheet 220 and the contact piece 231 of different polarities.

[0043] Reference Figure 1 According to a second aspect embodiment of the present invention, the track light includes the track light conductive connection mechanism of any of the first aspects of the present invention, so that the track light has a more stable and reliable sliding connection effect.

[0044] Specifically, the sliding box 200 is equipped with a track light body 900.

[0045] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
