[0002] Application No.: 202420978831.5; Application Date: May 7, 2024; Invention Title: A lamp connector that can be hidden in a track Technical Field

[0003] The present utility model relates to the technical field of lamps, and in particular to a gear regulator. Background Art

[0004] Currently, as a flexible lighting solution, the track lighting system is widely used in various indoor lighting fields such as commercial, office, and display. In such a system, track lights are usually equipped with a dedicated electrical box, which undertakes the important function of connecting the lamp to the power track and realizing power transmission. However, there is a significant technical defect in the design of the electrical box of track lights in the prior art.

[0005] When the electrical box structure of traditional track lights is combined with the track, due to design reasons, some of its structures often protrude beyond the track plane, forming irregular protrusions. For example, for a 3L3N integrated connector disclosed in Patent CN202320179037.X, after it is installed on the track, the lamp holder mounting holes 13 for installing the lamp, the four-gear adjustment knob 20, and the lock head all protrude from the track. This protruding design not only destroys the overall line beauty of the track light, reduces the coordination and integration degree of the space design, but also is particularly prominent in modern interior decoration that pursues a minimalist style and concealed installation requirements. Moreover, the protruding electrical box may also limit the installation of the lamp, making it difficult to fully fit the ceiling or other installation surfaces, affecting the layout flexibility in actual applications.

[0006] In addition, such protruding electrical box structures are prone to becoming obstacles during daily maintenance and cleaning, increasing unnecessary safety hazards and possibly affecting the stability and service life of the lamp itself. In view of the various problems existing in the prior art mentioned above, it is urgent to develop a new type of track light electrical box structure that can be optimized and integrated, achieve smooth transition, reduce visual interference, and improve installation concealment to meet the increasingly demanding lighting design aesthetics and technical standard requirements.

Detailed implementation mode

[0041] For the convenience of those skilled in the art to understand, the following combines the embodiments with the drawings to further explain the present utility model. The content mentioned in the implementation mode does not limit the present utility model. The following describes the present utility model in detail with reference to the drawings.

[0042] The lamp connector that can be hidden in the track provided in this embodiment, such as Figures 1 to 18 , includes a housing 1, a rotating module and a control module. The rotating module and the control module are both installed in the housing 1. The housing 1 is provided with a lamp slot 2, and the lamp slot 2 is assembled with a lamp; when connected to an external guide rail, the housing 1 is embedded in the external guide rail; as Figure 18 shown, after the housing 1 of this embodiment is installed on the guide rail, it can be completely hidden in the guide rail, which can effectively prevent direct contact of external factors with electrical components, reduce the risk of accidental electric shock, and at the same time prevent environmental factors such as dust and moisture from eroding the electrical components, improving the safety and stability of the electrical system; in addition, the concealed structure can save space, especially in narrow or special space environments, such as inside walls, ceilings or equipment, this design helps to integrate space resources and avoid occupying extra space.

[0043] Among them, the control module includes a circuit board 3, such as Figure 4 and Figure 10As shown, several pads are provided at one end of the circuit board 3 close to the rotation module, and corresponding conductive sheets 4 are welded to the pads, serving as the access terminals for the live wire and neutral wire for power supply to the circuit board 3. The rotation module is equipped with several electrical connection sheets. As Figures 5 to 7 shown, the electrical connection sheet includes a conductive contact 5 and a rotating contact sheet 6. The conductive contact 5 contacts the conductive sheet 4. Therefore, when the rotating contact sheet 6 is electrically connected to the guide rail, the circuit board 3 is powered and the lamp can be used.

[0044] In the housing 1 of this embodiment, a rotation locking member is installed. The rotation locking member is used to control the rotation, locking or unlocking of the rotation module; when the rotation module is in the locked state, the rotating contact sheet 6 extends out of the housing 1 and is electrically connected to the external guide rail; when the rotation module is in the unlocked state, the rotating contact sheet 6 rotates into the housing 1 and disconnects from the external guide rail; during operation, the locking piece 15 can be controlled to be loosened or tightened by Figure 8 a certain method. When the locking piece is in Figure 8 the loosened state on the right, the locking piece 15 can be further controlled to rotate, that is, rotate clockwise or counterclockwise along Figure 2 a certain direction, driving the rotation module to rotate clockwise or counterclockwise along Figure 2 a certain direction, so that the rotating contact sheet 6 rotates into the housing, achieving the purpose of disconnecting from the external guide rail and facilitating the disassembly of this embodiment from the guide rail.

[0045] Specifically, as Figures 5 to 8 shown, the rotation module includes a rotating block. The housing 1 is provided with a rotation groove 10. The rotating block is rotatably assembled in the rotation groove 10. The shape of the rotation groove 10 is adapted to the rotating block. And several positioning plates 20 are installed inside the housing 1. The positioning plates 20 are arranged close to the circuit board 3. Several limiting plates 17 are also provided on the inner side of the housing 1. A rotation groove 10 is formed between the limiting plates 17 and the positioning plates 20; the limiting plates 17 are all provided with avoidance arc surfaces 19, and the positioning plates 20 are all provided with positioning arc surfaces 21 adapted to the rotating block, so that the rotating block can rotate in the rotation groove 10; further, the positioning plates 20 are also provided with conductive limiting grooves 22 for limiting the conductive sheet 4, so that the position of the conductive sheet 4 can be fixed and the installation of the conductive sheet 4 can be made more stable; furthermore, as Figures 4 to 9 shown, the rotating block is provided with a first limiting groove 18, and the limiting plate 17 is assembled in the first limiting groove 18. Thus, the rotating block can rotate, and at the same time, under the limiting effect of the limiting plate 17, the displacement of the rotating block can be avoided, ensuring the normal contact between the rotating contact sheet 6 and the guide rail. The rotating block is also provided with a rotation avoidance groove 12. One end of the conductive sheet 4 in contact with the conductive contact 5 is located in the rotation avoidance groove 12, so that the rotation of the rotating block is not restricted by the conductive sheet 4.

[0046] As Figures 5 to 7As shown in the figure, the rotating block is provided with an installation groove 11 for assembling the electrical connection piece, and the rotating contact piece 6 protrudes from the rotating block; the rotating block includes a left rotating block 7 and a right rotating block 8, both the left rotating block 7 and the right rotating block 8 are provided with slots for assembling the rotating contact piece 6, and an installation groove 11 is formed between the slots of the left rotating block 7 and the slots of the right rotating block 8. Moreover, a partition plate 9 is arranged between the left rotating block 7 and the right rotating block 8 to separate different rotating contact pieces 6 through the partition plate 9, avoiding the occurrence of short - circuit situations. As Figure 7 , connection protrusions 23 are arranged at both the top and bottom ends of the left rotating block 7, and connection card slots 24 are formed at both the top and bottom ends of the right rotating block 8. The connection protrusions 23 are snap - fitted into the connection card slots 24, thereby assembling the left rotating block 7 and the right rotating block 8 together.

[0047] As Figure 5 , Figure 6 and Figure 10 shown in the figure, a convex block 13 is installed at one end of the rotating block, the other end of the rotating block contacts the inner side of the outer shell 1, and the top side of the convex block 13 is at the same horizontal plane as the outer side of the outer shell 1; the outer periphery of the convex block 13 is arc - shaped; a U - shaped groove 14 is formed in the convex block 13. The rotation locking member includes a lock piece 15 and a rotating shaft 16. The rotating shaft 16 is located in the U - shaped groove 14 and is connected to the convex block 13 at both ends; the lock piece 15 is hinged to the rotating shaft 16. When the lock piece 15 locks the rotating block, the outer side of the lock piece 15 is at the same horizontal plane as the outer side of the outer shell 1.

[0048] Specifically, as Figure 5 and Figure 10 shown in the figure, locking grooves 25 are arranged on both sides of the lock piece 15, and locking blocks 26 protrude from the outer shell 1. When it is necessary to lock the rotating block, rotate the lock piece 15 until the lock piece 15 fits on the outer shell 1, and the two locking blocks 26 are respectively located in the two locking grooves 25. Thus, without the assistance of external force, the lock piece 15 is difficult to move, and the rotating block can be fixed. Among them, since one end of the lock piece 15 for assembling the rotating shaft 16 is a U - shaped structure, during the rotation in the reverse direction of the arrow of Figure 8 , the lock piece 15 will be gradually tightened until it is fixed on the outer shell 1; when it is necessary to unlock and rotate, rotate the lock piece 15 in the direction of the arrow of Figure 8 to unlock the rotating block, then rotate the lock piece 15, and the rotating block can be driven to rotate, thereby controlling the connection or disconnection between the rotating contact piece 6 and the guide rail; after the rotating contact piece 6 is disconnected from the guide rail, the outer shell 1 can be taken out, that is, this embodiment can be taken out from the guide rail. In this embodiment, the rotation module is installed in the outer shell 1, and the lock piece 15 can also be at the same horizontal plane as the surface of the outer shell 1, thereby realizing a hidden connection method with the guide rail.

[0049] This embodiment is also provided with a gear regulator assembly, which has multiple gears and can adjust the brightness, color temperature, etc. of the connected lamps. As Figures 10 to 15As shown, the gear shift regulator assembly includes a shifting unit and a gear selection unit; the gear selection unit includes a base 27 and a moving seat 28. The base 27 is provided with a plurality of static contacts 29, and the moving seat 28 is equipped with a moving contact. The shifting unit is used to drive the moving seat 28 to move, and the moving contact moves with the moving seat 28 and is used to connect different static contacts 29.

[0050] Among them, as Figure 10 and Figure 11 shown, four groups of static contacts 29 are arranged on the base 27, so there can be three gears. Of course, the number of gears can also be set according to actual needs, and this embodiment is not limited. The moving contact of this embodiment includes a connecting rod 32, connecting columns 33 arranged at both ends of the connecting rod 32, and a fixing column 34 arranged in the middle of the connecting rod 32. The moving seat 28 is provided with a fixing cavity 35 and a connecting cavity 36. A spring 37 is sleeved on the outer periphery of the connecting column 33. The connecting column 33 is assembled in the connecting cavity 36. Both ends of the spring 37 respectively abut against the cavity wall of the connecting cavity 36 and the connecting rod 32. The connecting rod 32 is abutted by the elastic force of the spring 37 to ensure stable contact between the connecting rod 32 and the static contact 29. The fixing column 34 is assembled in the fixing cavity 35; the shifting unit includes a dial 41 and stoppers 42 arranged at both ends of the wave plate. Clamping blocks 43 are arranged at both ends of the dial 41. A clamping groove 44 is formed between the two clamping blocks 43. The moving seat 28 is equipped with a moving protrusion 45, and the moving protrusion 45 is limited in the clamping groove 44; a sliding groove 46 is formed in the clamping block 43, and the stopper 42 protrudes with a limiting strip 47, and the limiting strip 47 is slidably assembled in the sliding groove 46; the housing 1 is provided with a dial hole 48, and the dial 41 is exposed in the dial hole 48. As Figure 15 shown, when the dial 41 moves, under the restriction of the limiting strip 47 of the stopper 42, the stopper 42 moves with the dial 41, so that the dial hole 48 of the housing 1 can be blocked to avoid hollowing out.

[0051] Specifically, as Figure 10 shown, when adjusting the gear, move the dial 41. The clamping groove 44 of the dial 41 drives the moving seat 28 to move, and the moving seat 28 drives the moving contact to move, so that the connecting rod 32 moves to different positions and contacts different static contacts 29 to realize the adjustment of the gear. Among them, the base 27 is provided with a wave track 38, the moving seat 28 is provided with a ball cavity 39, and a ball 40 is movably assembled in the ball cavity 39. The ball 40 moves along the wave track 38. As Figure 12 and Figure 13As shown, the trough point of the wave track 38 is located in the middle of the two static contacts 29. That is to say, when the ball 40 drops to the trough point of the wave track 38, it means that the connecting rod 32 connects the two static contacts 29. Therefore, the movement of the ball 40 can help the user understand whether the gear shift is completed. Further, the base 27 is provided with a moving rail, and the moving seat 28 is provided with a moving bar. The moving bar can be slidably assembled in the moving rail. When the moving seat 28 moves, the moving bar slides in the moving rail. Therefore, the moving seat 28 can be accurately moved through the setting of the moving rail, and it is not easy to be misaligned. Furthermore, in this embodiment, a protective shell is also provided. The protective shell covers the moving seat 28 and the base 27, thereby preventing the static contacts 29 and the moving contacts from coming into contact with other structures and causing poor contact.

[0052] In this embodiment, as Figure 3 shown, the housing 1 is provided with a first notch 49. The first notch 49 is equipped with a lamp connection assembly. The lamp connection assembly includes a lamp fixing block 50 and a lamp locking member 51. The housing 1 is provided with a first arc-shaped lamp groove 52. The lamp fixing block 50 is provided with a second arc-shaped lamp groove 53. The lamp groove 2 is formed between the first arc-shaped lamp groove 52 and the second arc-shaped lamp groove 53. After the lamp is installed in the lamp groove 2, the lamp fixing block 50, the lamp and the housing 1 are locked by the lamp locking member 51.

[0053] Specifically, when installing the lamp, place the lamp corresponding to the first arc-shaped lamp groove 52, and then install the lamp fixing block 50 into the first notch 49. Among them, connection edges 54 protrude from both sides of the first notch 49, and connection grooves 55 are opened on both sides of the lamp fixing block 50. The connection edges 54 are respectively inserted into the connection grooves 55 of the lamp fixing block 50, and then the lamp fixing block 50 is slid to fit with the first notch 49, and then the lamp, the lamp fixing block 50 and the housing 1 are locked by the lamp locking member 51 to complete the assembly of the lamp. In the lamp connection assembly of this embodiment, the lamp fixing block 50 is arranged flush with the housing 1, so it does not protrude from the housing 1. After the housing 1 is connected to the external guide rail, it can also be hidden in the housing 1 to achieve a hidden assembly, and the structure of the lamp connection assembly is simple and convenient for installing the lamp.

[0054] To make the connection between this embodiment and the external guide rail more stable, the housing 1 is also installed with a hook 56. The housing 1 includes an upper cover 57 and a lower cover 58 detachably connected to the upper cover 57. The hook 56 is provided with a convex rib 59. First card slots 60 are arranged on both sides of the convex rib 59. The lower cover 58 is provided with a second notch 61. The two side walls of the second notch 61 are limited in the first card slots 60. The upper cover 57 is provided with a clamping block 62. A second card slot 63 is opened on the convex rib 59. After the hook 56 is assembled into the second notch 61, the clamping block 62 is clamped into the second card slot 63.

[0055] Specifically, asFigure 3 , Figure 16 and Figure 17 As shown in Figure 17 , the hook 56 is detachable. During assembly, the hook 56 is inserted into the housing 1 along the second notch 61, and the locking block 62 is snapped into the second card slot 63 to fix the hook 56 to the housing 1. When assembling the housing 1 and the guide rail, after sliding the housing 1 into the guide rail, in addition to connecting through the rotating module, the hook 56 can also be snapped onto the track to make the assembly more stable. Additionally, when the hook 56 is not needed, the hook 56 can also be disassembled, making it flexible to use.

[0056] The housing 1 of this embodiment is composed of an upper cover 57 and a lower cover 58. As shown in Figure 9 and Figure 18 , a plurality of snap rings 64 are installed on the outer periphery of the upper cover 57, and the lower cover 58 is provided with an embedded groove 65, and a snap 66 is provided in the embedded groove 65. When assembling the upper cover 57 and the lower cover 58, the snap rings 64 are assembled in the embedded groove 65, and the snap 66 is snapped onto the snap rings 64 to fix the upper cover 57 and the lower cover 58 together. Of course, for more stable installation, screws can also be used to lock the upper cover 57 and the lower cover 58. This embodiment is not limited and can be set according to actual needs. Further, as shown in Figure 2 , limiting protrusions 67 are convexly provided on both sides of the housing 1. When the housing 1 is inserted into the guide rail, both limiting protrusions 67 are limited in the guide rail, making the housing 1 more stable in the guide rail and not easily falling off.
