Description

Technical Field

[0001] The utility model belongs to the technical field of low-voltage track lamps, and in particular relates to a novel universal shaft conductive device for low-voltage track lamps. Background Art

[0002] With the continuous development of lighting technology, low-voltage track lights have been widely used in various lighting occasions due to their energy-saving, environmental protection, wide illumination range, etc. However, existing low-voltage track lights have certain limitations in the design of conductive devices, such as the direct contact between the conductive track and the external environment, which is prone to electric shock and short circuit, and the connection between the conductive track and the shaft is not stable enough, which is easy to cause the structure to loosen due to vibration or impact, thus affecting the lighting effect and safety of use.

[0003] Traditional low-voltage track light designs usually lack the function of rotation adjustment, making it difficult for users to adjust the direction of the light according to actual needs. This not only limits the lighting effect, but also fails to meet the lighting requirements in different scenarios. In addition, existing low-voltage track lights also have many inconveniences in the assembly and assembly process. Due to the lack of effective packaging and positioning design, the connections between the components are often not strong enough and are easily loosened due to vibration or impact, resulting in unstable electrical connections and increasing the risk of electric shock and short circuits. When maintaining and replacing parts, it also takes a lot of time and effort to disassemble and install, increasing maintenance costs and time. These defects limit the performance and application scope of low-voltage track lights. Therefore, there is a growing demand for new low-voltage track lights that can provide rotation adjustment functions and convenient assembly and assembly.

[0004] In view of this, we propose a new low-voltage track light universal shaft conductive device to solve the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problem that the conductive track in the traditional technology is in direct contact with the external environment and is prone to electric shock and short circuit, the utility model proposes a novel universal shaft conductive device for a low-voltage track lamp.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A novel low-voltage track light universal shaft conductive device, comprising a shaft groove inner joint, a shaft groove universal joint and a shaft outer joint for connecting the shaft groove inner joint and the shaft groove universal joint;

[0008] The joint in the rotating shaft groove cooperates with the rear cover of the rotating shaft to package and position the conductive track A, the insulating bracket cover and the insulating bracket A in the joint in the rotating shaft groove;

[0009] The shaft groove universal joint cooperates with the shaft front cover to package and position the conductive track B, the insulating bracket B and the insulating bracket C in the shaft groove universal joint;

[0010] The outer joint of the rotating shaft is rotatably sleeved on the outer side of the inner ring of the rotating shaft, the inner ring of the rotating shaft is threadedly connected with the outer threaded portion at the top of the rotating shaft groove universal joint, and one end of the outer joint of the rotating shaft away from the rotating shaft groove universal joint is threadedly connected with the outer threaded portion at the bottom of the rotating shaft groove inner joint. Through the cooperation of the outer joint of the rotating shaft and the inner ring of the rotating shaft, the rotating shaft groove inner joint and the conductive track A can be horizontally rotated and adjusted relative to the conductive track B. On the one hand, the rotating shaft groove universal joint and the conductive track B can be horizontally rotated and adjusted relative to the rotating shaft groove inner joint and the outer joint of the rotating shaft, and on the other hand, the rotating shaft groove inner joint and the conductive track A can be horizontally rotated and adjusted relative to the rotating shaft groove universal joint and the conductive track B.

[0011] The shaft groove inner joint cooperates with the shaft rear cover to encapsulate and position the conductive track A, the insulating bracket cover and the insulating bracket A in the shaft groove inner joint. In this way, the conductive track A and the insulating bracket A are fixed to one end of the shaft outer joint. The shaft groove universal joint cooperates with the shaft front cover to encapsulate and position the conductive track B, the insulating bracket B and the insulating bracket C in the shaft groove universal joint. In this way, the conductive track B and the insulating bracket B and the insulating bracket C are fixed to the other end of the shaft outer joint.

[0012] The outer joint of the rotating shaft is rotatably sleeved on the outer side of the inner ring of the rotating shaft, and the inner ring of the rotating shaft is threadedly connected with the rotating shaft groove universal joint. One end of the outer joint of the rotating shaft away from the rotating shaft groove universal joint is threadedly connected with the inner joint of the rotating shaft groove. In this way, the inner joint of the rotating shaft groove and the universal joint of the rotating shaft groove are connected through the outer joint of the rotating shaft to form a rotatable structure.

[0013] Through the cooperation of the outer joint of the rotating shaft and the inner ring of the rotating shaft, the inner joint of the rotating shaft groove and the conductive track A can be adjusted horizontally relative to the conductive track B. This adjustment function allows the track light to adjust its direction as needed, improving the lighting effect and flexibility. The structural design of the device makes the assembly process simpler, reduces the complicated assembly steps, and improves production efficiency. Due to the threaded connection between the inner joint of the rotating shaft groove and the inner ring of the rotating shaft, it can be easily disassembled and installed when repairs or replacement of parts are required. The structural design is reasonable, the positioning of the conductive track and the insulating bracket is stable, the problem of poor electrical contact caused by movement is reduced, and the safety of operation is improved. Due to the rotation cooperation of the inner and outer joints of the rotating shaft, wear is reduced and the durability of the device is improved. The device can flexibly adjust the angle between the conductive track A and the conductive track B to meet different lighting needs. The device is suitable for various low-voltage track lights and has broad application prospects.

[0014] Preferably, the conductive track A is located in a track groove surrounded by the insulating bracket cover and the insulating bracket A. The insulating bracket cover and the insulating bracket A provide electrical insulation, effectively preventing the conductive track A from contacting the external environment, and reducing the risk of electrical short circuit. The design of the track groove makes the conductive track A more stable in the groove, avoiding displacement of the track during rotation or vibration, thereby maintaining a good electrical connection. The insulating bracket provides additional protection for the conductive track, preventing damage to the track by external objects, and increasing the service life of the track.

[0015] Preferably, the rear cover of the shaft is threadedly connected to the top of the joint in the shaft groove. The threaded connection provides a tightening connection method, which can ensure that the connection between the rear cover of the shaft and the joint in the shaft groove is more secure and not easy to loosen. The threaded connection design simplifies the installation process, and the connection can be completed by rotating the thread, which improves the assembly efficiency. The tight connection reduces the problems of structural instability and poor electrical connection caused by loose connection.

[0016] Preferably, the conductive track B is located in a track groove surrounded by the insulating bracket B and the insulating bracket C. Similar to the conductive track A, the insulating bracket B and the insulating bracket C provide electrical insulation to prevent the conductive track B from short-circuiting with other parts or the external environment. The design of the track groove makes the conductive track B more stable in the groove, ensuring the reliability of electrical connection during movement. The track groove structure facilitates the installation and maintenance of the conductive track B and simplifies maintenance work.

[0017] Preferably, the front cover of the shaft is threadedly connected to the bottom of the shaft groove universal joint. The threaded connection provides a strong connection, ensuring that the connection between the front cover of the shaft and the shaft groove universal joint will not loosen due to vibration or long-term use. The threaded connection helps to accurately align and ensure the correct fit between the front cover of the shaft and the shaft groove universal joint, thereby improving the accuracy of the overall structure. The threaded connection helps to maintain the structural integrity of the entire device and reduce the risk of structural failure caused by connection problems.

[0018] Preferably, the two ends of the conductive copper sheet A on the insulating bracket A are electrically connected to the conductive track A and the conductive parts on the connector in the shaft groove. The conductive copper sheet A provides a stable electrical connection, ensuring that the current can be smoothly transferred from the conductive parts of the connector in the shaft groove to the conductive track A, reducing the increase in resistance and heating caused by poor contact. The contact connection of the conductive copper sheet A helps to reduce the contact resistance, thereby reducing energy loss and heat generation.

[0019] Preferably, the two ends of the conductive copper sheet B on the insulating bracket B are electrically connected to the conductive track B and the conductive parts on the shaft groove universal joint. The conductive copper sheet B ensures good conductivity between the conductive track B and the shaft groove universal joint, thereby improving the conductivity of the entire device. The connection of the two ends of the conductive copper sheet B increases the overall stability of the structure and reduces poor contact caused by mechanical vibration. The design of the conductive copper sheet B enables the shaft groove universal joint to maintain good electrical connection during adjustment, thereby improving the flexibility of adjustment.

[0020] Preferably, the two ends of the conductive copper sheet C on the insulating bracket C are electrically connected to the conductive track B and the conductive component on the rotating shaft front cover. The conductive copper sheet C provides a stable connection between the conductive track B and the rotating shaft front cover, ensuring reliable current transmission. The connection method of the conductive copper sheet C helps to improve the structural strength between the rotating shaft front cover and the conductive track B, and increases the overall durability.

[0021] Preferably, the conductive component on the shaft groove universal joint is electrically connected to the conductive component on the shaft groove inner joint and the conductive component on the shaft outer joint. This design allows the shaft groove universal joint to maintain good electrical connection at different angles and directions, increasing the flexibility of use. By realizing the electrical connection between the conductive components on the shaft groove universal joint, the number of connection points is reduced, and the potential failure points are reduced. This design helps to optimize the electrical performance of the entire device, reduce the resistance of the connection points, and improve the current transfer efficiency.

[0022] Compared with the prior art, the technical effects and advantages of the utility model are:

Overall, the conductive device has become an ideal solution for low-voltage track lights with its versatility and wide applicability, and has broad application prospects.

[0024] The new low-voltage track light universal shaft conductive device ensures the stability of the conductive track and the reliability of the electrical connection through its unique structural design. The conductive tracks A and B are respectively encapsulated in the track groove by insulating brackets, and are electrically contacted with the rotating shaft joint through the buckle connection of the conductive copper sheet. This design not only reduces the risk of contact resistance and electrical failure, but also improves the current transmission efficiency and heat dissipation performance, thereby ensuring the long-term stable operation of the device.
