Description

Technical Field

[0001] This utility model relates to the field of lighting fixture accessories technology, and in particular to a lighting fixture conductive mechanism. Background Technology

[0002] In existing lighting technologies, especially adjustable-angle luminaires (such as track lights, spotlights, wall washers, etc.) used in commercial displays, architectural decoration, or home lighting, are usually required to achieve multi-directional rotation or angle adjustment of the luminaire body relative to the power supply base. To meet this requirement, traditional solutions often adopt the following conductive connection methods: (1) Fixed plug-in conductive structure: The luminaire is directly plugged into the base socket for conduction. Although this structure is simple, once plugged in, the luminaire cannot rotate, which limits the flexible adjustment of the illumination angle. (2) External wire connection: The luminaire is connected to the power supply through a flexible wire. Although a certain angle adjustment can be achieved, the exposed cable affects the aesthetics and is prone to breakage, poor contact, or safety hazards due to repeated bending. Existing rotating conductive mechanisms for luminaires are difficult to balance conductive reliability, mechanical flexibility, and industrial aesthetics. Summary of the Invention

[0003] This utility model addresses the problems of existing technologies by providing a conductive mechanism for lamps, enabling a rotatable and stable conductive connection between the lamp and the power supply line. It allows the connected lamp to rotate 360° for conductivity, improving usability. The conductive connector can rotate freely within the movable cavity, allowing the external lamp to be adjusted at any angle during installation or use without affecting the electrical connection, reducing the risk of poor contact. The elastic conductive pin and the conductive connector have a surface contact and elastic compression fit structure, maintaining good conductivity even under long-term use or slight vibration environments, effectively avoiding problems such as loosening and oxidation common in traditional plug-in structures.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a conductive mechanism for a lamp, which includes a support base and a circuit board installed in the support base. The support base has a movable cavity, and a conductive connector is rotatably disposed in the movable cavity. An elastic conductive pin is installed on the circuit board. The upper end of the elastic conductive pin protrudes into the movable cavity and slides against the conductive connector. One end of the conductive connector is located in the movable cavity, and the other end of the conductive connector is used to connect to an external lamp. A protective cover can also be detachably connected to the support base, and the movable cavity is formed between the protective cover and the upper end of the support base.

[0006] The support base has fasteners on both sides of its upper end, and the protective cover has fasteners on both sides. The fasteners have grooves that engage with the fasteners.

[0007] The inner wall of the movable cavity is provided with a limiting groove, which is slidably connected to the conductive connector. The outer peripheral wall of the conductive connector is provided with a limiting ring that is slidably connected to the limiting groove.

[0008] The conductive connector includes a rotating conductive part and a lamp connecting part connected to the rotating conductive part. The rotating conductive part is rotatably disposed in the movable cavity, and the lamp connecting part extends out of the movable cavity and is connected to an external lamp.

[0009] The outer wall of the lamp connection part is also provided with two alignment blocks.

[0010] The support base includes a bottom shell and a top shell. The lower end of the top shell is detachably connected to the upper end of the bottom shell. Support blocks are provided at the four corners of the inner wall of the bottom shell, and connection holes are provided on the support blocks. Fixing holes are provided through the four corners of the top shell, and the connection holes are corresponding to the fixing holes.

[0011] The conductive mechanism of the lamp further includes a counterweight base and a support rod. The bottom of the support base is provided with a mounting hole, and the upper end of the support rod is inserted into the mounting hole. A hollow screw is also installed at the upper end of the mounting hole. The hollow screw passes through the mounting hole and is screwed to the upper end of the support rod. A first wire-passing groove is provided through the support rod along its length. A fixed bushing is provided in the middle of the counterweight base. The lower end of the support rod is screwed to the fixed bushing. A second wire-passing groove is provided through the fixed bushing. A wire-passing hole is provided through the bottom of the counterweight base. The wire-passing hole is corresponding to and connected to the second wire-passing groove.

[0012] The beneficial effects of this utility model are:

[0013] This invention achieves a rotatable and stable conductive connection between the lamp and the power supply line by setting a movable cavity within the support base and rotatably installing a conductive connector within the movable cavity. Furthermore, the elastic conductive pin slides against the conductive connector; the circuit board has an upwardly extending elastic conductive pin whose tip extends into the movable cavity and maintains sliding contact with the surface of the conductive connector. When the conductive connector rotates around its axis, the elastic conductive pin, relying on its own elasticity, remains firmly against the surface of the conductive connector, thus maintaining a continuous and stable electrical connection. Furthermore, it enables 360° rotational conductivity of the connected lamp, improving usability. The conductive connector can rotate freely within the movable cavity, allowing the external lamp to be adjusted at any angle during installation or use without affecting the electrical connection. This is particularly suitable for scenarios requiring multi-directional adjustment, such as wall washer lights, track lights, and spotlights, ensuring a stable and reliable electrical connection. Furthermore, it reduces the risk of poor contact. The elastic conductive pin and the conductive connector have a surface contact and elastic compression fit structure, maintaining good conductivity even under long-term use or slight vibration, effectively avoiding problems such as loosening and oxidation common in traditional plug-in structures.

The support base 1 has a movable cavity 3, and a conductive connector 4 is rotatably disposed within the movable cavity 3. An elastic conductive pin 5 is mounted on the circuit board 2, with the upper end of the elastic conductive pin 5 protruding into the movable cavity 3 and slidingly abutting against the conductive connector 4. One end of the conductive connector 4 is located within the movable cavity 3, and the other end of the conductive connector 4 is used to connect to an external lamp. A protective cover 6 can also be detachably connected to the support base 1, and the movable cavity 3 is formed between the protective cover 6 and the upper end of the support base 1. Specifically, this utility model achieves a rotatable and stable conductive connection between the lamp and the power supply line by setting a movable cavity 3 in the support base 1 and rotatably installing a conductive connector 4 in the movable cavity 3; furthermore, the elastic conductive pin 5 slides against the conductive connector 4, and the circuit board 2 is provided with an upwardly extending elastic conductive pin 5, the tip of which extends into the movable cavity 3 and maintains sliding contact with the surface of the conductive connector 4. When the conductive connector 4 rotates around its axis, the elastic conductive pin 5 relies on its own elasticity to always keep close to the surface of the conductive connector 4, thereby maintaining a continuous and stable electrical connection; furthermore, the present invention... The connected light fixture can rotate 360° to conduct electricity, improving the flexibility of use. The conductive connector 4 can rotate freely within the movable cavity 3, allowing the external light fixture to be adjusted at any angle during installation or use without affecting the electrical connection. It is particularly suitable for scenarios such as wall washer lights, track lights, and spotlights that require multi-directional adjustment, and the electrical connection is stable and reliable. Furthermore, it can reduce the risk of poor contact. The elastic conductive pin 5 and the conductive connector 4 have a surface contact and elastic compression fit structure, which can maintain good conductivity even in long-term use or under slight vibration environment, effectively avoiding problems such as loosening and oxidation of traditional plug-in structures.

[0028] In this embodiment of the application, the upper end of the support base 1 is provided with a through hole 28 for the elastic conductive needle 5 to pass through, and the through hole 28 is connected to the movable cavity 3.

The inner wall of the movable cavity 3 is provided with a circumferential limiting groove 10, and the outer periphery of the conductive connector 4 is provided with a corresponding limiting ring 11. The cooperation of these two not only restricts the axial displacement of the conductive connector 4 but also guides it to rotate smoothly within the movable cavity 3, preventing wobbling or displacement and improving structural stability.

[0031] In this embodiment, the conductive connector 4 includes a rotating conductive part 12 and a lamp connecting part 13 connected to the rotating conductive part 12. The rotating conductive part 12 is rotatably disposed within the movable cavity 3, and the lamp connecting part 13 extends out of the movable cavity 3 and connects to an external lamp. The outer wall of the lamp connecting part 13 is also provided with two alignment blocks 14. Specifically, in the above configuration, the alignment blocks 14 are used for precise docking with the external lamp socket, ensuring correct installation direction and reliable contact, preventing mis-insertion or loosening. The alignment blocks 14 ensure that the lamp can only be connected in the correct direction, avoiding short circuits or damage due to reverse connection, and improving overall safety and compatibility.

[0032] In this embodiment, the support base 1 includes a bottom shell 15 and a top shell 16. The lower end of the top shell 16 is detachably connected to the upper end of the bottom shell 15. Support blocks 17 are provided at each of the four corners of the inner wall of the bottom shell 15, and connecting holes 18 are provided on the support blocks 17.

Furthermore, the protective cover 6 is quickly engaged with the fasteners 7 on the support base 1 via fasteners 8, forming a closed movable cavity 3. This configuration facilitates assembly, maintenance, and replacement of internal components.

[0034] In Embodiment 2 of this application, as Figures 7 to 9As shown, the conductive mechanism of the lamp also includes a counterweight base 20 and a support rod 21. The bottom of the support base 20 is provided with a mounting hole 22. The upper end of the support rod 21 is inserted into the mounting hole 22.

Of course, the counterweight base 20 of Embodiment 2 of this application can be installed on a work platform or suspended on a bracket or ceiling. Specifically, the bottom of the support base 1 is provided with a mounting hole 22, into which the upper end of the support rod 21 is inserted and fixed by a hollow screw 23 passing through the mounting hole 22 from above. In this way, both the connection strength is guaranteed and the quick assembly and disassembly are convenient. Furthermore, in the second embodiment of this application, an internal through-type wiring channel is formed. The support rod 21 is provided with a first wiring groove 24 along the axial direction. The fixed bushing 25 in the middle of the counterweight base 20 is provided with a second wiring groove 26. The bottom of the counterweight base 20 is provided with a wiring hole 27 communicating with the second wiring groove 26. The three are aligned in sequence to form a continuous hidden wiring path from the circuit board 2 through the support rod 21 to the outside of the base, for leading out power lines or signal lines.

[0035] Furthermore, in Embodiment 2 of this application, the counterweight stability and electrical integration are integrated. The counterweight base 20 not only provides physical stability, but its internal fixing bushing 25 also serves as a structural connection and cable channel, achieving a high degree of integration between mechanical support and electrical wiring. Among them, the hollow screw 23 serves both as a fixation and wiring tool. While locking the support rod 21, the inner hole of the hollow screw 23 can be used as a channel for cables to enter the support base 1, further optimizing the wiring path and avoiding exposed cables from affecting aesthetics or causing safety hazards. The internal wiring is protected by the outer shell, avoiding pulling, wear, or environmental interference. At the same time, the hollow structure reserves space for future addition of control lines, enhancing the product's upgrade potential.
