Description

Technical Field

[0001] The utility model relates to the technical field of driving power supply cases, and particularly relates to an LED driving power supply case. Background Art

[0002] An LED driving power supply is a power converter that converts a power supply into a specific voltage and current to drive an LED to emit light. Usually, the input of an LED driving power supply includes high-voltage power frequency alternating current (i.e., mains power), low-voltage direct current, high-voltage direct current, low-voltage high-frequency alternating current (such as the output of an electronic transformer), etc.

[0003] The driving power supply mainly includes an external driving power supply case and electronic devices inside the power supply case. For the convenience of assembly, the driving power supply case is usually detachable. Most of the existing driving power supply cases are installed by means of screw fastening. Since tools are required, the disassembly and assembly are inconvenient. Content of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide an LED driving power supply case, which includes: an upper case, a lower case and a pressing cover. The upper case and the lower case are connected by snap-fitting through a first interpenetrating buckle structure. The pressing cover and the lower case are connected by snap-fitting through a second interpenetrating buckle structure. There are two pressing covers, which are located on both sides outside the upper case. And at least part of the pressing cover is pressed against the upper case to generate a pre-tightening force acting on the upper case, so that the upper case is fastened to the lower case. The first interpenetrating buckle structure includes a first buckle formed on the outer side of the lower case and a first buckle hole opened on the upper case. The second interpenetrating buckle structure includes a second buckle formed on the outer side of the lower case and a second buckle hole opened on the pressing cover. The first buckle and the second buckle are respectively at both ends on the same side of the upper case. The upper case and the lower case are fixed by snap-fitting of the first buckle and the first buckle hole. The lower case and the pressing cover are fixed by snap-fitting of the second buckle and the second buckle hole.

[0005] In a further embodiment of the utility model, two corners at the diagonal of the lower case are recessed in an arc shape to form arc-shaped walls, and the first buckle is convexly formed outside the arc-shaped walls.

[0006] In a further embodiment of the utility model, the diagonal corners of the upper case are recessed to form avoidance positions, and the first buckle hole is opened on the avoidance position corresponding to the first buckle.

[0007] In a further embodiment of the utility model, a third buckle is further provided on the outer side of the lower case, and a buckle position is formed on the inner wall of the upper case. The third buckle and the buckle position are in snap-fitting cooperation.

[0008] In a further embodiment of the utility model, a notch is formed at one corner adjacent to the avoidance position on the upper case, and a pressing edge is formed on the outer edge of the notch. When the pressing cover is fixed on the lower case, the inner bottom surface of the pressing cover presses against the pressing edge to apply a pre-tightening force.

[0009] In a further embodiment of the present utility model, a wire passing hole is formed in the side between the lower shell and the gland, a wire clamping plate is arranged on the lower shell corresponding to the wire passing hole, and tooth parts for clamping wires are arranged on both the wire passing hole and the wire clamping plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] This driving power supply shell is mainly composed of three main components: an upper shell, a lower shell, and a gland. Among them, the upper shell and the lower shell are detachably clamped and disassembled through a first interpenetrating buckle structure, and the gland and the lower shell are detachably clamped and disassembled through a second interpenetrating buckle structure. No tools are required throughout the assembly process. The first buckle and the second buckle respectively correspond to the first buckle hole and the second buckle hole and are pressed in for clamping and fixing. When disassembling, press the first buckle and the second buckle to deform and then disengage. At the same time, the gland presses the edge of the upper shell to apply a pre-tightening force to achieve further fastening, improving the convenience of disassembly and assembly.

[0020] Such as Figure 1 An embodiment of the present utility model provides an LED driving power supply case, including: an upper case 1, a lower case 2 and a gland 3.

[0021] Wherein, the upper case 1 and the lower case 2 are snap-connected through a first interlocking buckle structure, and the gland 3 and the lower case 2 are snap-connected through a second interlocking buckle structure. It can be understood that the convenience of disassembly and assembly is simplified by this snap-connection form, and no tools are required, and it can be disassembled and assembled manually.

[0022] In this embodiment, two glands 3 are provided and are located outside both sides of the upper case 1, and at least part of the gland 3 is pressed against the upper case 1 to generate a pre-tightening force acting on the upper case 1, so that the upper case 1 is fastened to the lower case 2. During assembly, first fix the upper case 1 and the lower case 2, and then assemble the gland 3. The gland 3 further presses and fixes the upper case 1.

[0023] In this embodiment, specifically, the first interlocking buckle structure includes a first buckle 20 formed on the outer side of the lower shell 2 and a first buckle hole 10 formed on the upper shell 1. The second interlocking buckle structure includes a second buckle 21 formed on the outer side of the lower shell 2 and a second buckle hole 30 formed on the pressing cover 3. The first buckle 20 and the second buckle 21 are respectively located at two ends on the same side of the upper shell 1. The upper shell 1 and the lower shell 2 are fixedly connected by clamping the first buckle 20 with the first buckle hole 10, and the lower shell 2 and the pressing cover 3 are fixedly connected by clamping the second buckle 21 with the second buckle hole 30. Both the first buckle 20 and the second buckle 21 can undergo elastic deformation for quick disassembly and assembly.

[0024] Furthermore, at two diagonal corners of the lower shell 2, the corners are recessed inward along an arc to form arc-shaped walls 22. The first buckle 20 protrudes and is formed outside the arc-shaped walls 22. At the diagonal corners of the upper shell 1, there are recessed to form avoidance positions 11. The first buckle hole 10 is formed on the avoidance position 11 corresponding to the first buckle 20. The positions of the first buckle 20 and the first buckle hole 10 correspond to each other, and the upper surfaces of both the first buckle 20 and the second buckle 21 are inclined planes, facilitating sliding cooperation with the first buckle hole 10 and the second buckle hole 30 to quickly complete clamping and detachment.

[0025] Even further, a third buckle 23 is also provided on the outer side of the lower shell 2, and a buckle position 12 is formed on the inner wall of the upper shell 1. The third buckle 23 and the buckle position 12 are clamped and matched to further clamp and fix the upper shell 1 and the lower shell 2 together, improving the stability of the assembly.

[0026] In addition, a notch 13 is formed at a corner adjacent to the avoidance position 11 on the upper shell 1, and a pressing edge 14 is formed along the outer edge of the notch 13. When the pressing cover 3 is fixed on the lower shell 2, the inner bottom surface of the pressing cover 3 presses against the pressing edge 14 to apply a pre-tightening force, further improving the stability of the assembly and the overall firmness.

[0027] In this embodiment, moreover, a wire passing hole A is formed on the side between the lower shell 2 and the pressing cover 3. A wire clamping plate 24 is provided on the lower shell 2 corresponding to the wire passing hole A. Tooth portions for clamping wires are provided on both the wire passing hole A and the wire clamping plate 24, so that when a wire passes through the wire passing hole A, it is clamped and fixed by the tooth portions on the wire passing hole A and the wire clamping plate 24.
