Description

Technical Field

[0002] In recent years, lighting devices that can adjust the intensity of light (and correspondingly change the color of lighting) have gradually become popular among consumers. Such lighting devices are internally provided with dimming drivers, which can adjust the luminous flux of the light source through the dimming driver, and thus adjust the light intensity of the lighting device. Such dimming drivers need to electrically connect the internal electronic control board with the external light source through cables. Accordingly, a wire pressing portion with a serrated surface is provided in the housing of the dimming driver, and the cable is locked by biting the above-mentioned cable through two relatively arranged wire pressing portions. However, in the related art, the end cover and the bottom shell where the wire pressing portion is arranged are generally connected by screws, which is inconvenient to operate on site, and most of the such screws in the dimming drivers are made of plastic screw columns, which are prone to the problem of internal glue position missing after multiple locking, resulting in the phenomenon of being unable to lock.

[0036] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments based on the embodiments are intended to be used to explain the present application and cannot be understood as limiting the present application.

[0037] References to "one embodiment" or "an example" or "an example" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment disclosed in the present application. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0038] This embodiment provides a wire pressing structure for a dimming driver, such as Figure 1 , Figure 2 and Figure 3 As shown in , the wire pressing structure includes a bottom shell 1, an end cover 2 and a locking member 3. Among them, the bottom shell 1 is provided with a first wire pressing portion 10, the end cover 2 is provided with a second wire pressing portion 20, and the locking member 3 is used to lock and fix the end cover 2 to the bottom shell 1, so that the first wire pressing portion 10 and the second wire pressing portion 20 can cooperate with each other to lock the cable extending between the two. The locking member 3 in this embodiment is provided with a first limiting structure and a first snap-on member, the bottom shell 1 is provided with a first connecting block 11, and the end cover 2 is provided with a second connecting block 21, and the first connecting block 11 and the second connecting block 21 cooperate to form a second limiting structure adapted to the first limiting structure and a second snap-on member adapted to the first snap-on member. The first limiting structure cooperates with the second limiting structure to lock and fix the end cover 2 and the bottom shell 1 along the first set direction, so that the first wire pressing part 10 and the second wire pressing part 20 can apply pressure to the cable extending therebetween along the first set direction, and the first clip cooperates with the second clip to clamp and fix the end cover 2 and the bottom shell 1 along the second set direction, and the second set direction intersects with the first set direction.

[0039] By providing a locking member 3, and providing a second limiting structure and a second snap fitting that cooperate with the locking member 3 on the bottom shell 1 and the end cover 2, the first limiting structure and the second limiting structure cooperate to apply pressure to the first wire pressing portion 10 and the second wire pressing portion 20, thereby achieving the locking of the cable. The cooperation between the first snap fitting and the second snap fitting can prevent the cooperation between the first limiting structure and the second limiting structure from failing. That is, the locking member 3 can be used to fix the end cover 2 on the bottom shell 1, eliminating the use of screws in the related art.

[0040] The wire pressing structure can be applied to a dimming driver, for example Figure 4 and Figure 5As shown in , the dimming driver includes a circuit board, a terminal block 8 electrically connected to the circuit board, and the wire pressing structure provided in this embodiment. The circuit board is installed in the bottom shell 1, and the terminal block 8 is located between the bottom shell 1 and the end cover 2. Figure 4 As shown in , the first limiting structure in this embodiment includes a limiting slide groove 313, and the second limiting structure includes a limiting slide rail 40. The limiting slide groove 313 cooperates with the limiting slide rail 40 to achieve locking and fixing of the end cover 2 and the bottom shell 1 along the first set direction. At the same time, the locking member 3 cooperates with the limiting slide groove 313 and the limiting slide rail 40 to be slidably connected with the bottom shell 1 and the end cover 2 along the second set direction, that is, during the assembly operation, it is only necessary to align the limiting slide groove 313 with the limiting slide rail 40 and slide the limiting slide rail 40 into the limiting slide groove 313, thereby reducing the difficulty of the assembly operation. It is easy to understand that in other optional embodiments, the first limiting structure can also be designed to include a limiting slide rail, and correspondingly, the second limiting structure includes a limiting slide groove.

[0041] Further, combined with Figures 6 to 12 As shown in the figure, the structure and principle of the wire pressing structure provided in this embodiment are described in detail by taking the wiring operation of the dimming driver as an example:

[0042] Combination Figure 8 and Fig.12 As shown in the figure, the locking member 3 in this embodiment includes a connecting plate 31, which includes a long plate 310, side plates 311 arranged on both sides of the long plate 310 along the length direction of the long plate 310, and flanges 312 arranged on the side plates 311. The long plate 310, the side plates 311 and the flanges 312 surround a limiting slide groove 313 with a convex cross section. Figure 7 and Fig.11 As shown in , the first connection block 11 and the second connection block 21 both include a vertical plate 4 and a bending plate 5 arranged on the vertical plate 4, the bending plate 5 on the first connection block 11 and the bending plate 5 on the second connection block 21 are arranged in close contact and cooperate to form a limiting slide rail 40, and the bending plate 5 and the vertical plate 4 in the first connection block and the bending plate 5 and the vertical plate 4 in the second connection block respectively cooperate with each other to form a slideway 50 that slides and cooperates with the flange 312. Through the above structural design, the first limiting structure and the second limiting structure in this embodiment not only achieve the limiting of the end cover 2 and the bottom shell 1 through the cooperation of the limiting slide rail 40 and the limiting slide groove 313 (the limiting refers to locking and fixing the end cover 2 and the bottom shell 1 along the first set direction), but also achieve the limiting of the end cover 2 and the bottom shell 1 through the cooperation of the flange 312 and the slideway 50, further enhancing the limiting effect.

[0043] In other optional embodiments, the limiting slide groove may also be a groove provided on the long board along the length direction of the long board, and correspondingly, the limiting slide rail may be a convex block provided on the vertical board and adapted to the aforementioned groove. In this arrangement, the aforementioned limiting effect can also be achieved through the cooperation between the convex block and the groove.

[0044] The locking member 3 in this embodiment includes the two connecting plates 31 mentioned above. Furthermore, the locking member 3 also includes an intermediate plate 30, and the two connecting plates 31 are fixedly connected to the two sides of the intermediate plate 30. Accordingly, two first connecting blocks 11 and two second connecting blocks 21 are provided, and the two first connecting blocks 11 are respectively located on the two sides of the first pressing portion 10, and the two second connecting blocks 21 are respectively located on the two sides of the second pressing portion 20. Through the above structural design, the locking member 3 can achieve a better effect of locking and fixing the end cover 2 and the bottom shell 1.

[0045] Combination Figure 6 and Fig.10 As shown in , the first clamping member in this embodiment includes a substrate 32 capable of generating elastic deformation and a first clamping block 33 disposed on the substrate 32, and the second clamping member includes two second clamping blocks 6 disposed on the first connecting block 11 and the second connecting block 21, respectively, and the first clamping block 33 is configured to be able to engage with or separate from the second clamping block 6 following the elastic deformation generated by the substrate 32. Specifically, the first clamping block 33 in this embodiment has a first engaging guide surface 330 and a first disengaging guide surface 331, and the second clamping block 6 has a second engaging guide surface 60 and a second disengaging guide surface 61. The first clamping block 33 and the second clamping block 6 are engaged with each other through the first engaging guide surface 330 and the second engaging guide surface 60, and the first clamping block 33 and the second clamping block 6 are separated from each other through the first disengaging guide surface 331 and the second disengaging guide surface 61.

[0046] It is easy to understand that the second set direction includes the engagement direction of the first card block 33 and the second card block 6 and the disengagement direction of the first card block 33 and the second card block 6, and the engagement direction is opposite to the disengagement direction. Along the engagement direction, the limiting slide groove 313 formed on the connecting plate 31 is aligned with the limiting slide rail 40 formed by the end cover 2 and the bottom shell 1, and inserted and slid. After reaching the set stroke, the first card-in guide surface 330 on the first card block 33 can be brought into contact with the second card-in guide surface 60 on the second card block 6. After that, the connecting plate 31 continues to move along the engagement direction, and the interaction between the first card-in guide surface 330 and the second card-in guide surface 60 can cause the base plate 32 to produce elastic deformation, thereby driving the first card block 33 to deviate relative to the second card block 6 and pass over the second card block 6, until the first card-in guide surface 330 is separated from the second card-in guide surface 60. Then, the base plate 32 will return to its original position and drive the first card block 33 to engage with the second card block 6. Similarly, when the first clamping block 33 needs to be separated from the second clamping block 6, the locking member 3 can be pulled along the disengaging direction. By applying force to the locking member 3, the base plate 32 is deformed, so that the first clamping block 33 can be separated from the second clamping block 6.

[0047] like Figure 5 As shown in , in order to facilitate the assembly operation and wiring operation of the dimming driver, the bottom shell 1 is designed to be split in this embodiment. Specifically, the bottom shell 1 in this embodiment includes a base 12 and a middle shell 13 arranged on the base 12, and the middle shell 13 can be disassembled relative to the base 12. Among them, the first wire pressing part 10 is fixedly arranged on the base 12, and the first connecting block 11 is fixedly arranged on the middle shell 13. The middle shell 13 cooperates with the base 12 to form a cavity for accommodating the circuit board in the dimming driver, and the base 12 cooperates with the end cover 2 to form a wiring cavity for accommodating the wiring terminals 8 in the dimming driver. It is easy to understand that the wiring cavity is adjacent to the cavity and is conductive. During assembly, the electric control board 7 electrically connected to the wiring terminals 8 is first fixedly installed on the base 12, and then the middle shell 13 is covered and fixed on the base 12.

[0048] like Figure 4 As shown in the figure, in this embodiment, a wire management hole 300 is provided on the middle plate 30 for the cable 9 to extend from the outside into the wiring cavity. Of course, in other optional implementations, the wire management hole that plays the above role can also be provided on the bottom shell or the end cover, as long as the cable first passes between the first wire pressing part and the second wire pressing part and then extends into the wiring terminal for wiring.

[0049] When performing wiring operations, first pass the cable 9 through the wire management hole 300 and through the first wire pressing part 10 on the bottom shell 1, and then connect the cable 9 to the terminal 8. Afterwards, the end cover 2 is placed on the bottom shell 1, and the second wire pressing part 20 cooperates with the first wire pressing part 10 to bite the cable 9 to achieve wire locking. Specifically, in this embodiment, one of the first connecting block 11 and the second connecting block 21 is provided with a positioning column 210, and the other is provided with a positioning hole 110, and the end cover 2 is placed on the bottom shell 1 through the positioning column 210 and the positioning hole 110. Finally, align and insert the limiting slide groove 313 on the locking member 3 with the limiting slide rail 40 formed on the bottom shell 1 and the end cover 2, so that the locking member 3 slides along the second set direction until the first buckle on the locking member 3 is engaged with the second buckle formed on the bottom shell 1 and the end cover 2.

[0050] When disassembling, the locking member 3 only needs to be pulled outward relative to the bottom shell 1, so that the first snap member is deformed and disengaged from the second snap member, and the locking member 3 can be slid and removed relative to the bottom shell 1 and the end cover 2, and then the end cover 2 is removed to expose the connection terminal 8. In order to facilitate the operator to apply force, in this embodiment, a push-pull portion 314 is further provided on the outer surface of the connecting plate 31 in the locking member 3, and anti-slip grooves are provided on the push-pull portion 314 to facilitate the operator to apply force.

[0051] The dimming driver equipped with the wire pressing structure provided in this embodiment can be applied to a lighting device. Specifically, the lighting device includes a light source and the dimming driver. The dimming driver is electrically connected to the light source and controls the light output intensity of the light source.

[0052] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Those skilled in the art should understand that the present application includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present application will be included in the scope of the claims.
