Description

Technical Field

[0001] The utility model relates to the technical field of LED drive power supply structure, in particular to an LED drive power supply housing suitable for a downlight. Background Art

[0002] At present, the outer shell of LED driver power supply is mostly in the shape of a cuboid, with the inlet end at one end of the cuboid shell and the outlet end at the other end of the cuboid shell, which effectively separates the inlet end and the outlet end to prevent the two from being too close to each other and causing a short circuit. Therefore, when the outer shell of the current LED driver power supply is installed in the downlight, one end of the outer shell is extended along the inner wall of the downlight accommodating cavity until the other end of the outer shell is also completely included in the downlight accommodating cavity, thereby completing the installation; this installation method causes the wire at one end (inlet end or outlet end) of the LED driver power supply shell to be bent and led out of the accommodating cavity together with the wire at the other end, for electrical connection between the external device and the LED driver power supply, which causes the bent lead wire to be easily broken due to metal fatigue, and the downlight will cause the LED driver power supply to shake inside the downlight during movement, further aggravating the possibility of the bent lead wire breaking, and at the same time, the LED driver power supply shakes violently inside the downlight, which may cause the circuit board in the LED driver power supply shell to be damaged by impact.

[0028] The following will be combined with Figures 1 to 5 , to describe an LED driver power supply housing applicable to a downlight in an embodiment of the present utility model.

[0029] An LED driver power supply housing applicable to a downlight includes a housing body 1; the outer periphery of the housing body 1 is formed corresponding to the cross-sectional contour of the inner wall of the accommodation cavity of the downlight, the housing body 1 can be completely accommodated in the accommodation cavity of the downlight, the bottom of the housing body 1 is fixed in the accommodation cavity of the downlight, the top of the housing body 1 faces the entrance of the accommodation cavity of the downlight, and an inlet slot 11 and an outlet slot 12 are arranged side by side on the upper part of the housing body 1, and a partition structure 13 is arranged between the inlet slot 11 and the outlet slot 12;

[0030] A circuit board 2 is arranged in the housing body 1, the inlet end 21 of the circuit board 2 is installed in the inlet slot 11, and the outlet end 22 of the circuit board 2 is installed in the outlet slot 12.

[0031] In a preferred embodiment of the LED driving power supply housing applicable to downlights proposed by the present utility model, as Figures 1 to 2 shown, the outer periphery of the housing body 1 is formed corresponding to the cross-sectional contour of the inner wall of the accommodating cavity of the downlight. For example, if the downlight is cylindrical, the outer periphery of the housing body 1 is correspondingly circular; if the downlight is cuboid, the outer periphery of the housing body 1 is correspondingly rectangular. In this way, the outer periphery of the housing body 1 can be inserted into the downlight from the entrance of the accommodating cavity of the downlight, cooperate with the inner wall of the downlight for limiting, and be completely accommodated in the accommodating cavity of the downlight, so that the LED driving power supply will not shake during the movement of the downlight, avoiding damage to the circuit board 2 caused by impact. At the same time, the bottom of the housing body 1 is fixed in the accommodating cavity of the downlight, the top of the housing body 1 faces the entrance of the accommodating cavity of the downlight, and an inlet through groove 11 and an outlet through groove 12 are arranged in parallel at the upper part of the housing body 1, so that the incoming line (the wire is connected to the incoming line end 21) and the outgoing line (the wire is connected to the outgoing line end 22) of the LED driving power supply can be led out of the housing together from the entrance of the accommodating cavity of the downlight, facilitating the connection of the incoming and outgoing lines to external devices, and the wire does not need to be bent and is not easily broken. More importantly, a partition structure 13 is arranged between the inlet through groove 11 and the outlet through groove 12, effectively isolating the incoming line end 21 and the outgoing line end 22 of the circuit board 2, avoiding short circuit due to the incoming line end 21 and the outgoing line end 22 being too close.

[0032] Further, the partition structure 13 is a longitudinal partition structure 131, and the top surface of the longitudinal partition structure 131 is higher than the top surfaces of the incoming line end 21 and the outgoing line end 22.

[0033] In this embodiment, the partition structure 13 can be a longitudinal partition structure 131, such as a longitudinally arranged long board, as Figure 1 shown. When the top surface of the longitudinal partition structure 131 is higher than the top surfaces of the incoming line end 21 and the outgoing line end 22, the creepage distance between the incoming line end 21 and the outgoing line end 22 can be increased longitudinally, which is applicable to the situation where the lateral space of the downlight is small and the longitudinal space is large.

[0034] Further, the partition structure 13 is a transverse partition structure 132, and the transverse partition structure 132 is used to extend the distance between the inlet through groove 11 and the outlet through groove 12.

[0035] In this embodiment, the partition structure 13 can be a transverse partition structure 132, such as a transversely arranged long board, as Figure 5 shown. The distance between the inlet through groove 11 and the outlet through groove 12 is extended, thereby extending the distance between the incoming line end 21 and the outgoing line end 22, achieving the purpose of increasing the creepage distance transversely, which is applicable to the situation where the lateral space of the downlight is large and the longitudinal space is small.

[0036] Further, the outer housing 1 includes an upper receiving groove housing 14 and a lower base 15; the partition structure 13, the incoming line through groove 11, and the outgoing line through groove 12 are all provided on the upper side of the upper receiving groove housing 14. The bottom groove opening of the upper receiving groove housing 14 and the lower base 15 are snap-fastened to fix the circuit board 2 within the upper receiving groove housing 1, and the bottom of the upper receiving groove housing 14 is fixed within the receiving cavity of the downlight.

[0037] In this embodiment, as Figures 3 to 4 shown, since the bottom of the outer housing 1 is fixed within the receiving cavity of the downlight through the bottom of the upper receiving groove housing 14, the incoming line through groove 11 and the outgoing line through groove 12 should both be provided on the upper side of the upper receiving groove housing 14, facing the entrance of the receiving cavity of the downlight. At the same time, being located on the side is based on the design rules of a general circuit board: designing the incoming and outgoing lines at the edge of the circuit board and reserving most of the space for the installation of the main circuit. Thus, after the bottom groove opening of the upper receiving groove housing 14 and the lower base 15 are snap-fastened to fix the circuit board 2 within the upper receiving groove housing 1, the incoming line end 21 and the outgoing line end 22 of the circuit board 2 can respectively pass through the incoming line through groove 11 and the outgoing line through groove 12 for installation. At this time, the partition structure 13 should also be provided on the upper side of the upper receiving groove housing 14 to facilitate the partitioning of the incoming line through groove 11 and the outgoing line through groove 12.

[0038] Further, a circuit board upper limiting member 141 is provided within the upper receiving groove housing 14. The bottom surface of the circuit board upper limiting member 141, the bottom surface of the incoming line through groove 11, and the bottom surface of the outgoing line through groove 12 all abut against the top surface of the circuit board 2;

[0039] On the top surface of the lower base 15, a circuit board lower limiting member 151 is provided. The outer periphery of the circuit board lower limiting member 151 is fitted and connected to the inner wall of the upper receiving groove housing 14, and the top surface of the circuit board lower limiting member 151 abuts against the bottom surface of the circuit board 2.

[0040] In this embodiment, the snap-fastening relationship between the upper receiving groove housing 14 and the lower base 15 is mainly achieved by the fitting connection between the outer periphery of the circuit board lower limiting member 151 and the inner wall of the upper receiving groove housing 14; the fixing relationship of the circuit board 2 is that after the upper receiving groove housing 14 and the lower base 1 are snap-fastened, the bottom surface of the circuit board upper limiting member 141, the bottom surface of the incoming line through groove 11, and the bottom surface of the outgoing line through groove 12 all abut against the top surface of the circuit board 2, and the top surface of the circuit board lower limiting member 151 abuts against the bottom surface of the circuit board 2, clamping the top and bottom surfaces of the circuit board 2 to form a fixing relationship.

[0041] Further, at least two fixing positions 142 are provided on the outer periphery of the bottom of the upper receiving groove housing 14; the fixing positions 142 are used to cooperate with fixing members to fix the bottom of the upper receiving groove housing 14 within the receiving cavity of the downlight.

[0042] In this embodiment, the bottom of the upper receiving groove housing 14 is fixed in the receiving cavity of the downlight through the fixing positions 142 on the outer periphery of the bottom. For example, the fixing position 142 is a semi-circular step, and there is a threaded hole column in the receiving cavity of the downlight corresponding to abut against the bottom surface of the semi-circular step. The tail of the screw (fastening member) is tightened into the threaded hole, and the screw head is limited to the semi-circular step, thereby fixing the bottom of the upper receiving groove housing 14 in the receiving cavity of the downlight. It should be noted that the fixing relationship between the bottom of the upper receiving groove housing 14 and the receiving cavity of the downlight can also be a snap-fit, fitting, etc. relationship, as long as the two are fixed to each other.

[0043] Further, the upper limit member 141 on the circuit board includes at least one limit block, and the limit block is arranged on the inner wall of the upper receiving groove housing 14, and the bottom surface of the limit block abuts against the top surface of the circuit board 2.

[0044] In this embodiment, in order to enable the upper limit member 141 on the circuit board and the bottom surfaces of the incoming line through groove 11 and the outgoing line through groove 12 to form a more balanced supporting force on the circuit board 2 and prevent the circuit board 2 from being offset, the upper limit member 141 on the circuit board should be composed of at least one limit block, forming a multi-point support with the bottom surfaces of the incoming line through groove 11 and the outgoing line through groove 12. For this reason, the limit block is preferably arranged on the inner wall of the upper receiving groove housing 14 (when there are multiple limit blocks, they are preferably evenly distributed on the inner wall), supporting the circuit board 2 at the edge of the circuit board 2, and avoiding hindering the components located above the circuit board 2 from extending into the groove of the upper receiving groove housing 14.

[0045] Further, the lower limit member 151 on the circuit board is a groove body, and the groove wall of the groove body is arranged corresponding to the bottom groove opening of the upper receiving groove housing 14. The outer periphery of the groove wall of the groove body is in fitting connection with the inner wall of the upper receiving groove housing 14, and the top surface of the groove wall of the groove body abuts against the bottom surface of the circuit board 2.

[0046] In this embodiment, the lower limit member 151 on the circuit board is preferably a groove body, which can realize fitting connection with the inner wall of the upper receiving groove housing 14 and form a supporting force on the bottom surface of the circuit board 2. At the same time, the space in the groove can also provide an extension space for the components (such as surface-mounted resistors, chips, etc.) located below the circuit board 2.

[0047] Further, at least one snap groove 143 is provided on the inner wall of the upper receiving groove housing 14, and a snap block 152 is provided on the outer periphery of the lower limit member 151 on the circuit board corresponding to the snap groove 143; when the outer periphery of the lower limit member 151 on the circuit board is in fitting connection with the inner wall of the upper receiving groove housing 14, the snap groove 143 and the snap block 152 are snap-connected.

[0048] In this embodiment, in order to make the snap-fit relationship between the upper receiving groove housing 14 and the lower base 15 more firm, at least one snap groove 143 is provided on the inner wall of the upper receiving groove housing 14, and a snap block 152 is provided on the outer periphery of the lower limit member 151 on the circuit board corresponding to the snap groove 143, and the snap groove 143 and the snap block 152 are snap-connected to achieve enhanced fixation.

[0049] Furthermore, the number of the snap grooves 143 is an even number, and the snap grooves 143 are symmetrically arranged.

[0050] In this embodiment, in order to make the snap connection points of the snap grooves 143 and the snap blocks 152 evenly distributed and prevent partial disengagement of the upper accommodation groove housing 14 and the lower base 15, it is preferred that the number of the snap grooves 143 is an even number, and the snap grooves 143 are symmetrically arranged, and the snap blocks 152 are correspondingly arranged, so that the snap connection points are evenly distributed.
