[0002] In the lighting industry, track lights are a common type of lighting equipment, and their design and assembly process has a significant impact on the overall performance, cost-effectiveness, and user experience of the product. The installation method of traditional connectors is quite complex, mainly due to the fixing of the grounding spring and the independent hand crank. The grounding spring usually requires additional plastic parts and M3*25 screws for secure fixing, while the hand crank also relies on screws and other fasteners for fixation.

[0003] This fixing method requires precise assembly techniques to ensure that the screws pass accurately through the pre-drilled holes and achieve the desired tightening effect, increasing the complexity and time cost of the assembly process. Furthermore, this fixing method not only increases the difficulty of assembly but also increases overall production costs and material consumption due to the need for additional fasteners.

[0004] In view of this, it is indeed necessary to propose a lever assembly, connector and luminaire to solve the above problems. Utility Model Content

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0047] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0048] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0049] Please see Figures 1 to 12 As shown, this utility model discloses a lighting fixture 300, which is a track lamp. The lighting fixture 300 includes a track (not shown), a connector 100, and a lamp body 200 for illumination. The track is installed on a mounting base such as a ceiling or wall. A groove is provided within the track, extending in the same direction as the track's length. The connector 100 is at least partially accommodated in the groove and can slide along it. A wire is provided within the track, including a live wire, a neutral wire, and a ground wire. After the connector 100 is installed, the wire is electrically connected to the connector 100. The lamp body 200 is detachably installed on the connector 100 and rotatably connected to it. The lamp body 200 can rotate relative to the connector 100 to adjust the illumination angle.

[0050] The connector 100 is used for electrically connecting the guide rail and the lamp body 200. In this embodiment, the upper end of the connector 100 can slide along the guide rail, and the lower end of the connector 100 is used to connect the lamp body 200. Specifically, the connector 100 includes a housing 1, a connecting rod 3, and a third swing rod 2 and a swing rod assembly 4 installed at both ends of the housing 1. The connecting rod 3 is fixed to the bottom of the housing 1 and is used to connect the lamp body 200.

[0051] Please see Figures 2 to 4 As shown, the top of the housing 1 has a first through hole 11 and a second through hole 12 extending horizontally, and the interior of the housing 1 has a receiving cavity (not shown). The rocker arm assembly 4 is assembled into the first through hole 11 via a beveled buckle 4321. The third rocker arm 2 is mounted into the second through hole 12 via a mounting buckle 22. The housing 1 also has a first limiting member 13 located beside the first through hole 11 and a second limiting member 14 located beside the second through hole 12. In this embodiment, the first limiting member 13 and the second limiting member 14 are protrusions, which are used to lock the rocker arm assembly 4 and the third rocker arm 2, respectively.

[0052] The third swing arm 2 includes an abutment portion 21, a first swing arm 23 disposed on one side of the abutment portion 21, and a mounting buckle 22 disposed at the lower end of the abutment portion 21. The third swing arm 2 passes through the second through hole 12 via the mounting buckle 22 and engages with the bottom surface of the second through hole 12 to assemble the third swing arm 2 into the second through hole 12. That is, the third swing arm 2 is installed in the second through hole 12 via the mounting buckle 22 without the need for additional screws, simplifying the installation process and improving installation efficiency.

[0053] Specifically, the mounting buckle 22 includes a first elastic element 221 and a second elastic element 222, and a deformation groove 223 located between the first elastic element 221 and the second elastic element 222. The bottoms of the first elastic element 221 and the second elastic element 222 are provided with inclined surfaces to facilitate the mounting buckle 22 entering the through hole. When the third rocker arm 2 passes through the second through hole 12, the first elastic element 221 and the second elastic element 222 are compressed by the inner wall of the second through hole 12, causing them to move closer together and tighten, thereby reducing the deformation groove 223. Once the mounting buckle 22 of the third rocker arm 2 passes through the first through hole 11, the first elastic element 221 and the second elastic element 222 are no longer compressed and spring back to their original shape, increasing the deformation groove 223. At this point, the first elastic element 221 and the second elastic element 222 abut against the bottom surface of the second through hole 12, thus achieving the engagement of the mounting buckle 22 with the second through hole 12.

[0054] In some preferred embodiments, the second through hole 12 can also be replaced by a through groove, which extends downward from the housing 1 and gradually narrows. That is, the diameter of the groove is positively correlated with its height, and the farther the groove is from the bottom surface of the housing 1, the smaller the cross-sectional diameter at that point. The mounting buckle 22 can fit tightly with the gradually narrowing groove, which helps to improve the connection strength between the mounting buckle 22 and the housing 1.

[0055] To further limit the position of the first swing arm 23 after installation, a first limiting groove 231 is provided at the bottom of the first swing arm 23. When the third swing rod 2 is installed on the housing 1 by the mounting buckle 22, the second limiting member 14 is received in the first limiting groove 231. In this embodiment, the first limiting groove 231 is an inwardly recessed groove, and the width of the groove is slightly larger than the protrusion. When the first swing arm 23 rotates, the protrusion will abut against both sides of the groove, thereby limiting the rotation amplitude of the first swing arm 23 and realizing the locking state of the third swing rod 2. After the connector 100 is installed, the contact between the protrusion and the first limiting groove 231 can effectively limit the rotation of the first swing arm 23 and prevent it from shaking. Similarly, when it is necessary to release the lock on the third swing rod 2, the first swing arm 23 is rotated in the opposite direction by force, so that the protrusion passes through the first limiting groove 231, and then the first swing arm 23 can swing freely.

[0056] One end of the connecting rod 3 is rotatably connected to the lower end of the housing 1, and the other end is rotatably connected to the lamp body 200. Furthermore, the connecting rod 3 has a hollow structure, allowing the wire to pass through and connect to the lamp body 200. Specifically, one end of the connecting rod 3 has a radially extending annular portion (not shown), which is housed in a receiving cavity of the housing 1, allowing the connecting rod 3 to rotate relative to the receiving cavity. The rotation of the connecting rod 3 drives the lamp body 200 to rotate, thereby adjusting the illumination angle.

[0057] Please combine Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the rocker arm assembly 4 includes a first rocker arm 41, a grounding spring 42, and a second rocker arm 43. The first rocker arm 41 includes a support portion 411, an extension portion 412 extending downward from the support portion 411, and a first through groove 413 penetrating the support portion 411 and the extension portion 412. The support portion 411 has a first pressure plate 4111 extending outward from its outer wall surface toward the first through groove 413. The first pressure plate 4111 has a first groove 4112 on the side facing the second rocker arm 43. The extension portion 412 has a first locking member 4121, which has a first locking portion 4122 protruding toward the first through groove 413 and a second locking portion 4123 protruding away from the first through groove 413. A rib 4125 is provided on the outer wall 4126 of the extension portion 412. The grounding spring 42 is used to insert into the first rocker arm 41.

[0058] Please see Figure 8 As shown, the grounding spring 42 includes a first portion 421 housed within a first through slot 413 and a second portion 422 exposed in an extension 412. A first slot 423 is provided on the first portion 421, recessed inward from the side of the first portion 421. The grounding spring 42 is inserted into the first through slot 413 from one side of the support portion 411, engaging with the first engaging portion 4122 to achieve a fixed connection between the grounding spring 42 and the first swing arm 41. Specifically, the first slot 423 and the first engaging portion 4122 are adapted and engaged, ensuring a secure connection between the two and guaranteeing good electrical contact between the grounding spring 42 and the first swing arm 41. With this configuration, the grounding spring 42 connects to the first swing arm 41 by directly inserting into the first through slot 413 from one side of the support portion 411, eliminating the use of traditional plastic parts and screws, simplifying the assembly process, and reducing assembly time and cost.

[0059] In some preferred embodiments, the widths of the first portion 421 and the second portion 422 are equal. A first inclined surface 424 is provided at the connection between the first portion 421 and the second portion 422, and the first inclined surface 424 slopes inward from the first portion 421. The first snap-fit ​​portion 4122 is provided with a second inclined surface 4124 corresponding to the first inclined surface 424, which serves as a guide during the installation of the grounding spring 42. When the grounding spring 42 is inserted into the first through slot 413 from the side of the bearing portion 411, the first inclined surface 424 can smoothly guide the grounding spring 42 into the second inclined surface 4124, reducing friction and resistance during installation and thus improving installation efficiency. Furthermore, during the snap-fit ​​process between the grounding spring 42 and the first swing rod 41, the second inclined surface 4124 can closely cooperate with the first inclined surface 424, forming a progressive snap-fit ​​effect, which helps to ensure a firm connection between the grounding spring 42 and the first swing rod 41.

[0060] In other embodiments, the first slot 423 is a square slot, and the first engaging portion 4122 is a buckle or protrusion adapted to the square slot. The square slot can be tightly engaged with the square buckle or protrusion, thereby improving the connection strength between the grounding spring 42 and the first swing rod 41.

[0061] In this embodiment, the second part 422 is fixedly connected to the ground wire, and the second part 422 is provided with a first hole 4221 for the wire to pass through. This arrangement facilitates the ground wire to pass through the first hole 4221 and be fixed by soldering, preventing the ground wire from detaching from the second part 422 due to external forces such as pulling or vibration. This reduces electrical faults or safety hazards caused by loose or detached ground wires, thereby improving the electrical safety performance of the entire rocker arm assembly 4.

[0062] In some preferred embodiments, the bottom ends of the second part 422 are provided with inclined surfaces on both sides, which are used to guide the grounding spring 42 to move downward.

[0063] Please see Figures 9 to 10 As shown, the second rocker arm 43 includes a main body 431, a mounting portion 432 extending downward from the main body 431, and a second through groove 433 penetrating the main body 431 and the mounting portion 432. The main body 431 has a second pressure plate 4311 extending outward from its outer wall surface toward the second through groove 433. The side of the second pressure plate 4311 facing the bearing portion 411 has a second groove 4312, and the first groove 4112 and the second groove 4312 are aligned with each other. The second rocker arm 43 also includes a third through groove 434 penetrating the main body 431 and the mounting portion 432. The third through groove 434 is located on one side of the second groove 4312 and is used to receive and limit the conductive spring piece 44.

[0064] The bottom of the mounting part 432 is provided with a slanted buckle 4321, and the mounting part 432 is installed in the first through hole 11 of the housing 1 through the slanted buckle 4321. The structure of the slanted buckle 4321 is similar to that of the mounting buckle 22, and will not be described in detail here. When the slanted buckle 4321 passes through the first through hole 11, the slanted buckle 4321 is squeezed by the inner wall of the first through hole 11, causing the slanted buckle 4321 to tighten inward; after the slanted buckle 4321 passes through the first through hole 11, the slanted buckle 4321 is no longer squeezed, begins to reset, and engages with the bottom surface of the first through hole 11. The second swing rod 43 is fixedly connected to the housing 1 by engaging the slanted buckle 4321 with the first through hole 11.

[0065] The mounting part 432 is also provided with a second latching member 4322 corresponding to the second latching part 4123. In this embodiment, the second latching member 4322 is an elastic buckle, and the second latching member 4322 has an inclined surface on the side facing the second latching part 4123, which facilitates the second latching part 4123 to slide downward and pass through the second latching member 4322. Specifically, pressing down on the first swing rod 41 to insert it into the second swing rod 43 will cause the second latching part 4123 to squeeze the second latching member 4322, causing the second latching member 4322 to move outward. When the second latching part 4123 moves to below the second latching member 4322, the second latching member 4322 is no longer squeezed and begins to return to its original position, thereby causing the second latching member 4322 to abut against the top of the second latching part 4123, preventing the second latching part 4123 from disengaging upward. The abutting engagement between the second locking part 4123 and the second locking piece 4322 ensures a firm connection between the first rocker arm 41 and the second rocker arm 43, enhancing the structural stability of the entire rocker arm assembly 4.

[0066] In some preferred embodiments, a foolproof groove 4331 is provided in the second through groove 433, and the protruding rib 4125 of the extension 412 is received in the foolproof groove 4331. The foolproof groove 4331 provides a clear guide and positioning point for the protruding rib 4125, so that the first rocker arm 41 can be accurately inserted into the second through groove 433 during installation, and can only be assembled in the correct direction, avoiding installation errors caused by misoperation. The foolproof design of the protruding rib 4125 and the foolproof groove 4331 simplifies the assembly process and improves installation efficiency and accuracy. The cooperation between the protruding rib 4125 and the foolproof groove 4331 increases the contact area and friction at the connection between the first rocker arm 41 and the second rocker arm 43, enhances the connection between the first rocker arm 41 and the second rocker arm 43, effectively prevents the first rocker arm 41 and the second rocker arm 43 from loosening or accidentally falling off during use, and further enhances the structural stability and reliability of the entire rocker arm assembly 4.

[0067] The second swing arm 43 is also provided with a second swing arm 435, which is located on one side of the main body 431. A second limiting groove 4351 is provided at the bottom of the second swing arm 435, and the first limiting member 13 is received in the second limiting groove 4351. When the second swing arm 43 is installed on the housing 1 via the inclined snap 4321, rotating the second swing arm 435 causes the first limiting member 13 to be received in the second limiting groove 4351. In this embodiment, the second limiting groove 4351 is an inwardly recessed groove, the width of which is slightly larger than the protrusion. When the second swing arm 435 rotates, the protrusion abuts against both sides of the groove, thereby limiting the rotation amplitude of the second swing arm 435 and achieving the locked state of the second swing arm 43. Similarly, when it is necessary to release the lock on the second swing arm 43, simply rotate the second swing arm 435 in the opposite direction to make the protrusion pass over the second limiting groove 4351, after which the second swing arm 435 can swing freely.

[0068] Please see Figures 11 to 12 As shown, the rocker arm assembly 4 also includes a conductive spring 44, which includes a first arm 441 and a second arm 442 that are perpendicular to each other. The first arm 441 is received within a receiving space formed by a first groove 4112 and a second groove 4312, which allows the first arm 441 to be tightly embedded therein, thereby reducing the wobbling of the first arm 441 and thus reducing loosening and poor contact in the electrical connection. The second arm 442 is received within a second through groove 433 and is located outside the extension 412.

[0069] Preferably, the second arm 442 is received in the third through slot 434, and both sides of the second arm 442 are engaged with the third through slot 434 to further limit the second arm 442.

[0070] The second arm 442 has a second hole 4421 for the wire to pass through. In this embodiment, the second arm 442 is fixedly connected to the live / neutral wire, and is generally connected after the rocker arm assembly 4 is installed. The second hole 4421 facilitates the insertion of the live / neutral wire, and soldering is performed on the second arm 442 to increase the connection strength between the two, which helps to prevent the wire from loosening or falling off due to vibration or external force during use, further improving the reliability of the electrical connection. The extension 412, the first groove 4112 and the second groove 4312 limit the conductive spring 44, ensuring a stable connection between the conductive spring 44 and the rocker arm assembly 4, so as to avoid poor contact caused by loosening.

[0071] In some preferred embodiments, the second arm 442 is provided with an abutment protrusion 4422, which is used to abut against the outer side wall 4126 of the extension 412, further limiting the second arm 442 within the second through groove 433, effectively preventing the second arm 442 from shifting and shaking during the process of being subjected to force or vibration.

[0072] The end of the second arm 442 is also provided with a bending member 4423 to increase the creepage distance, which helps to ensure electrical safety. The bending member 4423 is set at an angle greater than 90 degrees with the second arm 442 to prevent the second arm 442 from detaching from the second arm 442.

[0073] The installation process of the connector 100 is as follows: The grounding spring 42 is inserted into the first through slot 413 from one side of the support part 411. The inclined surface of the second part 422 will first contact the second inclined surface 4124 of the first rocker arm 41. The external force continues to drive the grounding spring 42 to move downward. The inner side of the first locking part 4122 is squeezed by the grounding spring 42, causing the first locking part 4122 to move outward, thereby increasing the distance between the two second locking parts 4123 and providing space for the grounding spring 42 to move downward. When the grounding spring 42 moves downward to the point where the first inclined surface 424 and the second inclined surface 4124 engage, the first locking part 4122 is no longer squeezed and returns to its original position. Through the engagement of the first slot 423 and the first locking part 4122, the second inclined surface 4124 and the first inclined surface 424 are tightly engaged, thereby achieving a tight engagement between the grounding spring 42 and the first rocker arm 41. At this point, the assembly between the grounding spring 42 and the first pendulum rod 41 is completed, that is, the first pendulum rod 41 is assembled.

[0074] Align the beveled latch 4321 of the second swing arm 43 with the first through hole 11 of the housing 1, and press the second swing arm 43 downwards so that the beveled latch 4321 of the second swing arm 43 passes through the first through hole 11 and engages with the bottom surface of the first through hole 11. The mounting part 432 is installed in the first through hole 11 of the housing 1 through the beveled latch 4321. At this time, the assembly between the housing 1 and the second swing arm 43 is completed.

[0075] Two conductive spring pieces 44 are inserted into the third through slot 434 respectively. The first arm 441 is received within the receiving space formed by the first groove 4112 and the second groove 4312, and the second arm 442 is received within the third through slot 434 and located outside the extension 412. Then, the protrusion 4125 of the assembled first rocker arm 41 is aligned with the anti-fooling groove 4331 of the second through slot 433, so that the first rocker arm 41 can be accurately inserted into the second through slot 433 during installation. Pressing down on the first rocker arm 41 causes the second locking part 4123 to press against the second locking member 4322, causing the second locking member 4322 to move outward. When the second locking part 4123 moves below the second locking member 4322, the second locking member 4322 is no longer compressed and begins to return to its original position, thereby causing the second locking member 4322 to abut against the top of the second locking part 4123, preventing the second locking part 4123 from detaching upward. At this point, the first rocker arm 41 and the second rocker arm 43 are fixedly connected by the abutment and locking of the second locking part 4123 and the second locking piece 4322. The installation of the rocker arm assembly 4 is now complete.

[0076] When the mounting clip 22 of the third rocker arm 2 is aligned with the second through hole 12 and inserted, the mounting clip 22 is pressed against the inner wall of the second through hole 12 and tightens inward. After the mounting clip 22 passes through the first through hole 11, the first elastic element 221 and the second elastic element 222 are no longer compressed and return to their original shape. At the same time, the first elastic element 221 and the second elastic element 222 abut against the bottom surface of the second through hole 12 to achieve the engagement of the mounting clip 22 with the second through hole 12. At this point, the installation of the third rocker arm 2 and the housing 1 is completed.

[0077] In summary, this utility model, by providing a first engaging portion 4122 protruding into the first through groove 413 and a second engaging portion 4123 protruding away from the first through groove 413 on the first engaging member 4121, achieves two key benefits. First, the engaging engagement of the first engaging portion 4122 with the grounding spring 42 forms a stable mechanical connection, ensuring good electrical contact and facilitating grounding effectiveness and electrical safety. Second, the engaging engagement of the second engaging member 4322 on the second swing arm 43 with the second engaging portion 4123 on the first swing arm 41 enables a fixed connection between the first swing arm 41 and the second swing arm 43. Thus, the engaging engagement between the first swing arm 41, the grounding spring 42, and the second swing arm 43 can be achieved using only the first engaging member 4121, eliminating the need for additional fasteners such as screws, and enabling quick and easy installation of the swing arm assembly 4, saving installation time and costs.
