Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of lighting equipment accessories, and specifically refers to a lamp driver box. Background Technology
[0002] Currently, LED lights or light strings are usually controlled by a driver box. The driver box usually contains a driver module for light control, which is often installed in the form of a PCB board inside the driver box.
[0003] However, commercially available driver boxes are usually simple in structure and are packaged with upper and lower covers, which are then secured with bolts. Due to the gaps, water leakage is likely to occur between the upper and lower covers and at the bolt connections, which can damage the internal materials and prevent long-term use. Summary of the Invention
[0004] The purpose of this invention is to provide a lamp driver box that effectively protects the interior of the box, improves sealing, and extends service life.
[0005] The purpose of this utility model is achieved as follows:
[0006] A lighting driver box includes an upper box and a lower box that snap together to form a cavity. A PCB board is disposed in the cavity. The lower edge of the upper box has a downwardly extending snap-fit edge, and the upper edge of the lower box has a snap-fit groove adapted to the snap-fit edge. The upper and lower boxes are snapped together and the snap-fit edge is fixed in the snap-fit groove by ultrasonic welding. Wire-passing half-holes are provided on the left and right edges of both the upper and lower boxes, and the upper and lower boxes are snapped together to form wire-passing holes. Wires are connected to both ends of the PCB board, and the two wires extend out of the wire-passing holes at both ends. Tail clips are fixed to the wires, and the tail clips have tail clip grooves that engage with the edges of the wire-passing half-holes.
[0007] The present invention is further configured such that a plurality of welding portions are spaced apart at the bottom of the snap-fit edge, and the bottom of the welding portions is formed with a welding end face.
[0008] The present invention is further configured such that the width of the welded portion is the same as the distance between adjacent welded portions.
[0009] The present invention is further configured such that the inner side of the bottom of the snap-fit groove is formed with abutment wall, and abutment wall notch is provided between the abutment walls in two adjacent directions.
[0010] The present invention is further configured such that a support frame for raising the PCB board is provided inside the lower box, and a plurality of limiting buckles of the same horizontal height are formed on the inner side wall of the lower box.
[0011] The present invention is further configured such that the tail clip includes a reinforcing part located on one side of the tail clip slot for preventing bending.
[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are:
[0013] 1. The lamp driver box provided by this utility model uses ultrasonic welding to fix the upper box body and the lower box body together. The wire hole through which the wires pass is sealed with a tail clip, which effectively improves the overall sealing performance and ensures the service life of the driver box.
[0014] 2. The present invention further adopts a welding part at the bottom of the snap-fit edge, which can provide a certain amount of heat fusion during ultrasonic welding, thereby enhancing the sealing between gaps; at the same time, a certain spacing requirement is adopted to ensure that the heat fusion is more uniform and the sealing is further improved.
[0015] 3. The abutment wall provided in this utility model can prevent the melt from flowing into the cavity during hot melting, and the notch in the abutment wall can prevent the extrusion during hot melting, which would cause deformation.
[0016] 4. The support frame and limiting buckle provided by this utility model are used to fix the PCB board and prevent it from sliding. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 3:
[0027] A lighting driver box includes an upper box body 1 and a lower box body 2 that are fastened together to form a cavity. A PCB board 3 is disposed in the cavity. The lower edge of the upper box body 1 is formed with a downwardly extending snap-fit edge 10, and the upper edge of the lower box body 1 is formed with a snap-fit groove 20 that is adapted to the snap-fit edge 10. The upper box body 1 and the lower box body 2 are fastened together and the snap-fit edge 10 is fixed in the snap-fit groove 20 by ultrasonic welding. The upper box body 1 and the lower box body 2 are provided with wire-passing half holes 11 on the left and right edges, and the upper box body 1 and the lower box body 2 are fastened together to form wire-passing holes. The two ends of the PCB board 3 are connected with wires 4, and the two wires 4 extend out of the wire-passing holes at both ends. The wires 4 are fixed with tail clips 5, and the tail clips 5 are provided with tail clip grooves 50 that are fitted into the edges of the wire-passing half holes 11.
[0028] During implementation, a PCB board is placed inside the lower housing, with the wires at both ends passing through the through-holes 11 at both ends. During this process, the tail clip slot 50 on the tail clip aligns with the edge of the through-hole. The upper housing is then snapped down and ultrasonically welded for a secure connection. At this point, the through-hole of the upper housing also engages with the tail clip slot 50 of the tail clip. The completed drive box exhibits strong overall sealing, good protection, and convenient installation.
[0029] Preferably, the bottom of the snap-fit edge 10 is provided with a plurality of welding portions 12 at intervals, and the bottom of the welding portions 12 is formed with welding end faces.
[0030] Preferably, the width of the welded portion 12 is the same as the distance between adjacent welded portions 12.
[0031] In the above structure, ultrasonic welding heats the welded part 12 to a certain extent, so that it can fit into the snap-fit groove. Using a certain spacing can make the heat melting more uniform and the fit tighter.
[0032] Preferably, the inner side of the bottom of the snap-fit groove 20 is formed with abutment wall 21, and abutment wall notch 22 is provided between the abutment walls 21 in two adjacent directions.
[0033] Preferably, the lower box 2 is provided with a support frame 23 for raising the PCB board 3, and the inner side wall of the lower box 2 is formed with a plurality of limiting buckles 24 at the same horizontal height.
[0034] During implementation, several support frames 23 support the PCB board, suspending it in the cavity. The limiting buckle 24 is in the form of an inverted triangle block, which clamps the PCB board to a certain extent, fixing it and preventing slippage, thereby ensuring normal use.
[0035] Preferably, the tail clip 5 includes a reinforcing portion 51 located on one side of the tail clip slot 50 for preventing bending. The use of the reinforcing portion can provide the wire with a certain bending strength, while preventing the wire from being dragged and avoiding damage.
[0036] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
