Description

Technical Field

[0001] The utility model belongs to the technical field of driving power boxes, and particularly relates to a driving power box for track lights. Background Art

[0002] In the existing design, for example, the publication number is CN212108301U, and the utility model name is a power box structure for track lights, which includes: a housing, a circuit board and a track connector arranged in the housing. A pair of conductive clips are arranged at the edge of the circuit board, and the conductive clips are connected to the input end of the circuit board. A pair of conductive sheets matching with the conductive clips are arranged on the track connector. The circuit board and the track connector are connected by the cooperation of the conductive clips and the conductive sheets. Among them, the conductive clip member includes a fixed power connection part and two clip pieces. The two clip pieces are symmetrically fixed on the fixed power connection part on both sides, and there is a gap between the two clip pieces. The bottom of the fixed power connection part is provided with pin feet in a straight plug type or a patch type. The two clip pieces are fixed on the circuit board through the pin feet. The conductive sheet extends into the gap between the two clip pieces to abut against the two clip pieces and is electrically connected to the two clip pieces.

[0003] Adopting the above scheme, compared with the connection between the circuit board and the track connector through the power cord and the conductive sheet, the volume of the housing is effectively reduced. However, since the conductive sheet is clamped by the conductive clip, when the conductive clip is fatigued, virtual connection between the conductive sheet and the conductive clip is likely to occur. Moreover, due to the addition of the conductive clip, not only the installation of the conductive clip is required, but also a certain number of conductive clips need to be manufactured or purchased, which will further increase the assembly and material costs and is not conducive to the popularization of the track light power box.

Adopting the above scheme, since there is no need to set conductive clips and the fixed through slots and the fixed power connection parts are used in a matching manner for fixation, the fixation method is simple and it is not easy to generate virtual connection between the power connection metal sheet and the input pad due to the fatigue of the power connection metal sheet, overcoming the disadvantages that virtual connection between the conductive sheet and the conductive clip is likely to occur after the fatigue of the conductive clip in the traditional track light driving power box, and the addition of the conductive clip further increases the assembly and material costs, which is conducive to the popularization of the track light driving power box.

The power connection track is electrically connected to the two power connection metal sheets 140 through the conductive joint 130. One ends of the two power connection metal sheets 140 are electrically connected to the conductive joint 130, and the other ends of the two power connection metal sheets 140 are electrically connected to the control circuit board 120;

[0037] One end of the control circuit board 120 is provided with two fixed through slots 121. Input pads 122 are provided at positions inside and near the two fixed through slots 121 of the control circuit board 120. The other ends of the two power connection metal sheets 140 extend into the corresponding fixed through slots 121 to form fixed power connection parts 141. After the fixed power connection parts 141 are clamped in the corresponding fixed through slots 121, they abut against the corresponding input pads 122 and are electrically connected to the corresponding input pads 122.

[0038] In the present utility model, adopting the above solution, since there is no need to provide a conductive clip and the cooperation of the fixed through slot 121 and the fixed power connection part 141 is adopted for fixation, the fixation method is simple and it is not easy to cause the phenomenon of virtual connection between the power connection metal sheet 140 and the input pad 122 due to the fatigue of the power connection metal sheet 140. It overcomes the disadvantages that the conductive clip is prone to virtual connection with the conductive sheet after fatigue in the traditional track light driving power supply box, and adding a conductive clip further increases the assembly and material costs, which is beneficial to the popularization of the track light driving power supply box.

[0039] Such as Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 shown, specifically, the fixed power connection part 141 is a clamping power connection board formed by bending the other ends of the two power connection metal sheets 140 and extending them into the corresponding fixed through slots 121. The clamping power connection board abuts against the inner wall of the fixed through slot 121 and then abuts against and is electrically connected to the input pad 122.

[0040] In order to facilitate the insertion of the fixed power connection part 141 into the fixed through slot 121 for clamping, two end parts at one end of the fixed power connection part 141 extending into the fixed through slot 121 are contracted inward to form guiding sliding surfaces 1411, and the guiding sliding surfaces 1411 are used to facilitate the insertion of the fixed power connection part 141 into the fixed through slot 121 for clamping.

After the power connection metal sheet body 142 is embedded in the metal sheet fixing groove 1121, it is perpendicular to the second half power supply box housing 112, and the first half power supply box housing 111 presses the power connection metal sheet body 142 against the metal sheet fixing groove 1121;

[0044] One of the power connection portions 143 is an elastic power connection piece 143a extending from one of the two power connection metal sheet bodies 142 toward the conductive joint 130. The elastic power connection piece 143a abuts against the side of the conductive joint 130 and is electrically connected to the conductive joint 130;

[0045] The other of the power connection portions 143 is a power connection ring 143b extending from the other of the two power connection metal sheet bodies 142 toward the conductive joint 130.

A positioning convex block 1122 is provided inside the second half power supply box housing 112, and the positioning convex block 1122 is embedded in the positioning through groove 123; at a position of the first half power supply box housing 111 facing the positioning through groove 123, there is a abutting convex column 1111. The diameter of the abutting convex column 1111 is larger than the width of the positioning through groove 123, and the position where the abutting convex column 1111 abuts against the positioning through groove 123 presses the control circuit board 120 against the inside of the second half power supply box housing 112.

[0047] To enable the control circuit board 120 to connect out a power line and control the functions of the control circuit board 120, a detachable cover plate 1112 is installed on the first half power supply box housing 111. The control circuit board 120 is provided with output terminals 124 and a toggle switch 125 at positions corresponding to the detachable cover plate 1112, and the detachable cover plate 1112 is used to conveniently expose the output terminals 124 and the toggle switch 125.

The difference lies in that the structure of the fixed power connection part 241 is different from that in Embodiment 1. Among them, the fixed power connection part 241 is a V-shaped power connection part formed by bending the other ends of the two power connection metal sheets and extending them into the corresponding fixed through slots 221. The bottom of the V-shaped power connection part extends into the corresponding fixed through slot 221, and both ends of the V-shaped power connection part abut against the inner wall of the fixed through slot 221 and then abut against and are electrically connected to the input pad 222.

[0051] To enable the fixed power connection part 241 to be firmly clamped to the fixed through slot 221, a U-shaped elastic abutting part 244 is provided between the fixed power connection part 241 and the other end of the power connection metal sheet 240.
