Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a power supply for driving a panel light. Background Technology

[0002] The panel light source is LED. The light emitted by the LED forms a uniform planar light emission effect after passing through a light guide plate with high light transmittance, resulting in good uniformity of illuminance and soft light.

[0003] Panel lights typically connect to the driver in two ways: one is by connecting the driver with several screws, which is secure but cumbersome to install and remove; the other is by connecting the driver with clips and slots, which is convenient to install and remove but prone to loosening. In addition, the driver is installed inside the panel light, so the lamp cover on the back panel needs to be removed first when the driver needs to be installed or removed, which reduces maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a panel light driver power supply with the advantages of stable installation and convenient assembly and disassembly.

[0005] The technical solution of this utility model is as follows:

[0006] A panel light driver power supply includes a power supply housing and a connector. The power supply housing is detachably connected to a mounting port on a lamp back panel. The front of the lamp back panel has a connector that is electrically connected to the connector. The mounting port connects the front and rear sides of the lamp back panel. The side wall of the power supply housing and the inner wall of the mounting port are cylindrical in shape with similar dimensions. The side wall of the power supply housing and the inner wall of the mounting port are respectively provided with external and internal thread grooves that can be threaded together. The front of the power supply housing has a sliding groove A that communicates with the side wall of the power supply housing. A slider is slidably connected to the sliding groove A. An elastic element is installed between the inner end of the slider and the bottom of the sliding groove A. The outer end of the slider has a connector. When the power supply housing is rotated to the front end of the mounting port, the connector is located on the extension line of the sliding groove A. The back of the power supply housing has a sliding groove B that is in the same direction as the sliding groove A and communicates with it. A lever is slidably connected to the sliding groove B. The front end of the lever is fixedly connected to the slider.

[0007] Preferably, the elastic element includes two springs, which are disposed between the slider and the bottom of the sliding groove A. The axial direction of the springs is in the same direction as the length direction of the sliding groove A, and the two springs are symmetrical about the axis of the sliding groove A along its length.

[0008] Preferably, the outer edge of the back of the power supply housing is provided with a fixing piece along the circumference, and the back of the lamp back plate is provided with a fixing groove corresponding to the fixing piece along the mounting opening. The groove opening on the fixing groove is located at the end point of the rotation trajectory of the fixing piece. When the power supply housing is rotated to the front end of the mounting opening, the fixing piece rotates into the groove opening of the corresponding fixing groove.

[0009] Preferably, a limiting ring is provided along the circumference of the rear end of the side wall of the power supply housing. When the power supply housing is rotated to the foremost end of the mounting port, the limiting ring abuts against the rear end of the mounting port.

[0010] Preferably, the back of the power supply housing is provided with finger grooves.

[0011] The beneficial technical effects of this utility model are as follows:

[0012] 1. The power supply housing and the lamp backplate mounting port are detachably connected by the use of external and internal thread grooves. Compared with using screws to connect the lamp backplate, the power supply housing is easier to install and remove. Compared with using clips and slots to connect the lamp backplate, the installation of the power supply housing is more stable.

[0013] 2. Users can assemble and disassemble the power supply housing and connector without removing the lamp cover on the front of the lamp back panel, improving maintenance efficiency. The lamp cover on the front of the lamp back panel does not block the rear end of the mounting port, allowing the power supply housing to easily enter and exit the mounting port. The lever is connected to the slider, and sliding grooves A and B, which are in the same direction, restrict the sliding direction of the slider and the lever, respectively. When the user pulls the exposed lever, the slider connected to the lever will move synchronously, thereby bringing the connector on the slider closer to or away from the connector seat, thus completing the assembly and disassembly between the connector and the connector seat. The elastic element is used to provide pressure to press the connector tightly onto the connector seat, reducing the risk of loosening between the connector and the connector seat.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example:

[0022] like Figures 1 to 4 As shown, this embodiment provides a panel light driver power supply, including a power supply housing 1 and a connector 2. The power supply housing 1 is detachably connected to the mounting port 3 of a lamp back plate 15. The front of the lamp back plate 15 is provided with a connector 4 electrically connected to the connector 2. The mounting port 3 connects the front and rear sides of the lamp back plate 15. The side wall of the power supply housing 1 and the inner wall of the mounting port 3 are cylindrical in shape with similar dimensions. The side wall of the power supply housing 1 and the inner wall of the mounting port 3 are respectively provided with external threads and internal thread grooves that can be threaded together. The front of the power supply housing 1 is provided with... The sliding groove A5 is connected to the side wall of the power supply housing 1. A slider 6 is slidably connected to the sliding groove A5. An elastic element 7 is installed between the inner end of the slider 6 and the bottom of the sliding groove A5. A connector 2 is provided at the outer end of the slider 6. When the power supply housing 1 is rotated to the front end of the mounting port 3, the connector 4 is located on the extension line of the sliding groove A5. A sliding groove B8 is provided on the back of the power supply housing 1. The sliding groove B8 is in the same direction as the sliding groove A5 and is connected to each other. A lever 9 is slidably connected to the sliding groove B8. The front end of the lever 9 is fixedly connected to the slider 6.

[0023] The power supply housing 1 and the lamp back plate 15 are detachably connected by using external and internal thread grooves. Compared with using screws to connect the lamp back plate 15, the power supply housing 1 is easier to install and remove. Compared with using clips and slots to connect the lamp back plate 15, the installation of the power supply housing 1 is more stable. Users can assemble and disassemble the power supply housing 1 and connector 2 without removing the lamp cover on the front of the lamp backplate 15, improving maintenance efficiency. The lamp cover on the front of the lamp backplate 15 does not block the rear end of the mounting port 3, allowing the power supply housing 1 to easily enter and exit the mounting port 3. The lever 9 is connected to the slider 6, and the sliding grooves A5 and B8, which are in the same direction, respectively restrict the sliding direction of the slider 6 and the lever 9. When the user pulls the exposed lever 9, the slider 6 connected to the lever 9 will move synchronously, thereby bringing the connector 2 on the slider 6 closer to or away from the connector 4, thus completing the assembly and disassembly between the connector 2 and the connector 4. The elastic element 7 is used to provide pressure to press the connector 2 tightly onto the connector 4, reducing the risk of loosening between the connector 2 and the connector 4.

[0024] Furthermore, the elastic element 7 includes two springs 10, which are located between the slider 6 and the bottom of the sliding groove A5. The axial direction of the springs 10 is in the same direction as the length direction of the sliding groove A5, and the two springs 10 are symmetrical about the axis of the sliding groove A5 along the length direction.

[0025] The two springs 10 provide sufficient pressure to clamp the connector 2, and the symmetrical distribution of the springs 10 ensures that the slider 6 is subjected to even force.

[0026] Furthermore, a fixing piece 11 is provided along the circumference of the outer edge of the back of the power supply housing 1, and a fixing groove 12 corresponding to the fixing piece 11 is provided along the mounting opening 3 on the back of the lamp back plate 15. The groove on the fixing groove 12 is located at the end of the rotation trajectory of the fixing piece 11. When the power supply housing 1 is rotated to the front end of the mounting opening 3, the fixing piece 11 rotates into the groove of the corresponding fixing groove 12.

[0027] With the help of the fixing groove 12 and the fixing piece 11, firstly, the power housing 1 connected to the fixing piece 11 can be accurately positioned. When the fixing groove 12 stops the fixing piece 11, the power housing 1 is in the correct position. Secondly, the use of the fixing groove 12 and the fixing piece 11 together increases the connection points between the power housing 1 and the lamp back plate 15, effectively improving the impact resistance of the power housing 1.

[0028] Furthermore, a limiting ring 13 is provided along the circumference of the rear end of the side wall of the power supply housing 1. When the power supply housing 1 is rotated to the front end of the mounting port 3, the limiting ring 13 abuts against the rear end of the mounting port 3.

[0029] The limiting ring 13 prevents the power supply housing 1 from being screwed too deeply into the mounting port 3, thus facilitating accurate positioning of the power supply housing 1.

[0030] Furthermore, the back of the power supply casing 1 is provided with a finger groove 14.

[0031] The finger groove 14 provides the user with a convenient point of force to rotate the power supply housing 1, thereby improving the efficiency of assembling and disassembling the power supply housing 1.

[0032] Working principle and usage process of this utility model:

[0033] When installing the power supply housing 1, insert it into the rear end of the mounting port 3. Then, rotate the power supply housing 1 to move it forward within the mounting port 3. During this process, the user pulls the lever 9 to retract the slider 6 and connector 2 into the sliding groove A5. When the power supply housing 1 is at the front end of the mounting port 3, the user moves the lever 9 back to extend the slider 6 and connector 2, allowing the connector 2 to close with the connector 4 to complete the connection. When removing the power supply housing 1, first pull the lever 9 to retract the slider 6 and connector 2 into the sliding groove A5, pull the connector 2 out of the connector 4, then rotate the power supply housing 1 out of the mounting port 3, and finally release the lever 9.

[0034] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
