Description

Technical Field

[0001] This utility model belongs to the field of magnetic lamp technology, specifically relating to an ultra-thin magnetic lamp with a novel power connection method. Background Technology

[0002] Magnetic lights are installed on magnetic tracks, allowing for easy adjustment of the lighting angle. They can be used as track spotlights or accent lighting. Traditional magnetic lights typically consist of a magnetic track, a power supply box, and the light fixture. Track lights are mostly used in commercial settings, such as offices, clothing stores, star-rated hotels, museums, exhibition halls, professional shop windows, and counters—places requiring decorative effects and focused lighting.

[0003] Currently, magnetic lights, which consist of a magnetic rail, a power supply box, and a lamp, are connected to the magnetic rail by magnetic attraction. In existing technology, the conductive copper strip on the magnetic rail is mostly installed on the top wall of the groove. After the power supply box is installed, it is electrically connected to the conductive copper strip through a spring contact on the top surface of the power supply box. Although this can achieve a conductive connection, the conductive copper strip is exposed in the part where the power supply box is not installed, which affects the aesthetics of the product. Moreover, due to the weight of the power supply box, poor contact between the conductive spring contact and the conductive copper strip is also likely to occur, which will affect the stability of the connection of the power supply box, thus affecting the stability and reliability of the product.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example

[0038] See Figures 1 to 4 As shown, an ultra-thin magnetic lamp with a novel power connection method includes a magnetic track 1 and a switching power supply box 2. The bottom surface of the magnetic track has two parallel n-shaped conductive grooves 3. In this embodiment, the magnetic track is a conventional structure of the prior art, so it is not described in detail, but simply applied. The conductive contacts in the two n-shaped conductive grooves are connected to the positive and negative poles of the power supply, respectively.

[0039] In practical applications, a C-shaped locking groove 4 is provided on the side wall of the n-shaped conductive groove, and a limiting protrusion 5 is provided on the top and bottom walls of the C-shaped locking groove; the limiting protrusion is mainly used for the installation and positioning of the conductive contact base. When installing the conductive contact base, it can be inserted from one end of the C-shaped locking groove.

[0040] During installation, a conductive contact holder 6 is fitted into the C-shaped slot, and a conductive contact 7 is inserted into the side of the conductive contact holder. The side of the conductive contact holder has a copper slot 18, and the conductive contact is positioned within the copper slot. The top and bottom surfaces of the conductive contact holder have limiting grooves that mate with the limiting protrusions. Two conductive springs 8 are provided on the power supply box; the lower part of each conductive spring is arc-shaped and protrudes towards the conductive contact. During installation and use, the power supply box is fitted into the n-shaped conductive groove, and the conductive springs abut against the conductive contacts for electrical connection. Power is drawn through the interaction of the conductive springs and conductive contacts. In this embodiment, both the conductive springs and conductive contacts are made of copper. The conductive contact holder is made of insulating plastic or insulating ceramic.

[0041] Meanwhile, to improve the stability and reliability of installation, a V-shaped locking groove 9 is provided on the side wall of the n-shaped conductive groove; wherein, the V-shaped locking groove is parallel to the C-shaped locking groove and the V-shaped locking groove is located below the C-shaped locking groove; and, the bottom surface of the switching power supply box is provided with a locking lug 10, and the outer wall of the locking lug is provided with a V-shaped locking protrusion 11; during installation and use, the switching power supply box is inserted into the n-shaped conductive groove, and the V-shaped locking protrusion is locked into the V-shaped locking groove for limitation.

[0042] To improve the stability and reliability of the installation and prevent loosening or detachment, the switching power supply box 2 includes a box body 21 and a cover 22 connected by snap-fit. In practical applications, the box body and cover can also be fixed with screws, which is a conventional replacement in existing technology and is not described in detail. In practical applications, a push-button switch 23 is provided on the side of the box body; a limit protrusion 12 is provided on the bottom wall of the box body; a stop protrusion 13 is provided on the push-button switch, and an arc-shaped stop protrusion 14 is provided in the middle of the stop protrusion. A protrusion 15 is fixed to the end of the convex strip; in actual application, the box body is provided with a mounting groove 16 and a mounting boss 17; the conductive spring is inserted into the mounting groove, and the end of the conductive spring is attached to the boss and fixed with screws; the push switch is a conventional structure of the prior art, so it is not described in detail, but simply applied. When the push switch is pressed, the arc-shaped abutment protrusion engages between the latch ear and the limiting protrusion to limit the latch ear, and the protrusion engages between the conductive spring and the boss to limit the conductive spring. The latch ear is limited by the arc-shaped abutment protrusion, and the conductive spring is limited by the protrusion. At this time, the positions of the two are stable and will not loosen or fall off. When opened, there is a certain displacement space between the latch ear and the limiting protrusion, and there is also a certain displacement space between the conductive spring and the boss. At this time, under the action of external force, the switching power supply box can be pulled out from the magnetic track, which improves the convenience and stability of use.

[0043] This utility model has positive effects: The structure of this utility model is reasonably designed. It has a C-shaped locking groove on the side wall of the n-shaped conductive groove, and a conductive contact seat and a conductive contact are set in the C-shaped locking groove. In conjunction with the two conductive springs on the switching power supply box, the conductive springs abut against the conductive contact to make electrical connection during installation. When the switching power supply box is not installed, the conductive contact is hidden on the side wall, which can improve the overall aesthetics. Moreover, setting it on the side wall can also ensure the effectiveness of the electrical connection between the conductive contact and the conductive spring, which is conducive to improving the conductivity stability. It has strong applicability and good practicality.

[0044] Furthermore, it is equipped with a C-shaped latching groove that works in conjunction with the latching lugs and V-shaped latching protrusions on the power supply box. Through the above structure, the effectiveness and reliability of the latch can be guaranteed.

[0045] In practical applications, the switching power supply box includes a snap-fit ​​body and a cover. A push-button switch is located on the side of the body. A limit protrusion is located on the bottom wall of the body. The push-button switch has a stop protrusion with an arc-shaped stop protrusion in the middle. A protrusion is fixed to the end of the stop protrusion. When the push-button switch is pressed, the arc-shaped stop protrusion engages between the snap-fit ​​lug and the limit protrusion, limiting the snap-fit ​​lug. The protrusion also engages between the conductive spring and the boss, limiting the conductive spring. This structure ensures the stability of the switching power supply box installation on the magnetic track. After the stop protrusion is positioned, the snap-fit ​​lug and conductive spring of the switching power supply box are fixed and cannot deform, preventing loosening or detachment. When the switch is turned on and the snap-fit ​​lug and conductive spring are no longer fixed, the switching power supply box can be removed. This improves the stability and reliability of use, making it highly applicable and practical.

[0046] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
