Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and in particular to an LED power supply box. Background Technology

[0002] LED driver power supplies are power converters that convert power supply into specific voltage and current to drive LEDs to emit light. As a new type of light source that is widely used and developing rapidly, LED light sources have advantages over traditional light sources, such as energy saving, high efficiency, small size, long life, fast response speed, low driving voltage, and excellent shock resistance. As a result, they can rapidly develop and expand the industry scale and market share. Under the guidance of industry trends, their technology is also constantly being updated and deepened.

[0003] Currently used LED driver power supply boxes consist of a box body and a cover. The box body and cover can be connected in the following two ways:

[0004] 1. The box body and the lid are fixed together with screws. The assembly and disassembly process requires the use of tools such as screwdrivers or electric screwdrivers, which is cumbersome, time-consuming and labor-intensive.

[0005] 2. The box body and the cover are connected by snaps, and there are gaps at the connection, which makes it easy for dust to enter and affect the service life of the circuit board and its components inside the power supply box.

[0006] In summary, the current structure of LED driver power supply boxes cannot meet the usage requirements. Summary of the Invention

[0007] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide an LED power supply box that has stable connection, good dustproof effect and is easy to assemble.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] An LED power supply box includes a box body and a box cover. The box body has a mounting cavity for mounting a circuit board, and inlet and outlet holes are respectively provided at both ends of the box body.

[0010] A support ring is fixedly installed on the inner side of the upper end of the box body, and an inner ring is fixedly installed on the inner side of the support ring. The box body, the support ring, and the inner ring form an annular groove. Several slots are opened on both sides of the box body, and the slots are connected to the annular groove.

[0011] The box cover is fixedly mounted with a connecting ring facing downwards, and a ring plate is fixedly mounted outwards at the lower end of the connecting ring. The connecting ring and the ring plate are inserted into the ring groove. The two sides of the box cover are fixedly mounted with buckles of the same number as the card slots, and the buckles are engaged with the card slots.

[0012] In this way, the circuit board is fixedly installed in the mounting cavity of the box, and the circuits connected to the circuit board pass through the inlet and outlet holes, which is the existing structure. During the assembly of the box and the cover, the connecting ring and the ring plate are inserted into the ring groove, and the buckle enters the ring groove and engages with the slot to complete the connection; during disassembly, push the buckle inward, the buckle disengages from the slot, and the cover can be removed.

[0013] The bottom of the annular groove is fixedly installed with a bottom sealing gasket, and the annular plate is in contact with the bottom sealing gasket.

[0014] The inner ring has a side sealing ring fixedly installed on its outer side wall, and the connecting ring is in contact with the side sealing ring.

[0015] The inner circumferential side of the box is fixedly equipped with several protruding ribs, and the upper end of the protruding ribs is fixedly connected to the support ring.

[0016] The bottom sealing gasket and the side sealing gasket are integrally formed.

[0017] In summary, this LED power supply box has the advantages of stable connection, good dust protection, and easy assembly. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0024] like Figure 1-5As shown, an LED power supply box includes a box body 1 and a box cover 2. The box body has a mounting cavity for mounting a circuit board, and inlet holes 3 and outlet holes are respectively opened at both ends of the box body.

[0025] A support ring 4 is fixedly installed on the inner side of the upper end of the box body, and an inner ring 5 is fixedly installed on the inner side of the support ring. The box body, the support ring, and the inner ring form an annular groove 6. Several slots 7 are opened on both sides of the box body, and the slots are connected to the annular groove.

[0026] The box cover is fixedly mounted with a connecting ring 8 facing downwards. The lower end of the connecting ring is fixedly mounted with a ring plate 9 facing outwards. The connecting ring and the ring plate are inserted into the ring groove. The two sides of the box cover are fixedly mounted with buckles 10 in the same number as the card slots. The buckles are engaged with the card slots.

[0027] In this way, the circuit board is fixedly installed in the mounting cavity of the box, and the circuits connected to the circuit board pass through the inlet and outlet holes, which is the existing structure. During the assembly of the box and the cover, the connecting ring and the ring plate are inserted into the ring groove, and the buckle enters the ring groove and engages with the slot to complete the connection; during disassembly, push the buckle inward, the buckle disengages from the slot, and the cover can be removed.

[0028] During implementation, a bottom sealing gasket is fixedly installed at the bottom of the annular groove, and the annular plate is in contact with the bottom sealing gasket. This forms a bottom seal, blocking dust from entering through the groove and improving the dustproof effect.

[0029] In practice, a side sealing ring is fixedly installed on the outer wall of the inner ring, and the connecting ring fits against the side sealing ring. This forms a side seal, blocking dust that enters through the slot and improving the dustproof effect.

[0030] During implementation, several protruding ribs 11 are fixedly installed circumferentially on the inner side of the box body, and the upper end of the protruding ribs is fixedly connected to the support ring. This improves the overall strength of the box body.

[0031] In practice, the bottom sealing gasket and the side sealing gasket are integrally molded, which facilitates manufacturing.

[0032] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
