Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a magnetic power supply, a magnetic guide rail unit provided with the magnetic power supply, and a lighting system including the magnetic guide rail unit. Background Art

[0002] With the rise of the trend of no-main-lamp lighting design, the magnetic track light lighting system has become one of the mainstream products of indoor lighting systems. The magnetic track light is a type of linear lighting fixture. It uses magnetic technology to adsorb and fix the magnetic power supply and magnetic lamp on the magnetic track, and the magnetic power supply and the magnetic lamp are electrically connected through the conductive strips in the magnetic track, so that the magnetic power supply can power the magnetic lamp located at any position on the magnetic track through the magnetic track.

[0003] The existing magnetic power supply mainly includes a track power supply component, a shell and a power supply component. The track power supply component is installed on the shell. The track power supply component is used to assemble with the magnetic guide rail and establish an electrical connection with the conductive strip in the magnetic guide rail. The power supply component is installed in the shell and electrically connected to the track power supply component. Among them, the magnetic power supply needs to be grounded, and the existing grounding method is to use a ground wire to electrically connect the shell and the circuit board of the power supply component. Specifically: a first through hole is provided at each end of the shell, and each end of the circuit board is welded and fixed to the first end of a ground wire, and the second end of the ground wire is fixedly connected to a wire ear; when the shell and the power supply component are assembled, the bolt is first passed through the connecting hole and the second through hole of the corresponding ground wire wire ear, and then the bolt is threadedly connected to the nut placed in the shell, and then the wire ear is fixed in the shell under the cooperation of the bolt and the nut to establish an electrical connection between the shell and the circuit board of the power supply component.

[0004] However, the grounding structure between the housing of the existing magnetic power supply and the circuit board of the power supply assembly has the following shortcomings:

[0005] First, when the connection between the bolt and the nut becomes loose, unreliable grounding may occur.

[0006] Second, when assembling the housing and the power supply component, it is necessary to first place the nut and the wire lug in the housing, align the threaded hole of the nut and the second through hole on the wire lug with the first through hole on the housing, and then pass the bolt through the first through hole, the second through hole and the threaded hole in sequence to cooperate with the nut to fix the housing and the wire lug. However, due to the limited space in the housing, it is difficult to position the wire lug and the nut, making it difficult to align the first through hole, the second through hole and the threaded hole, which greatly increases the difficulty of installation and makes the assembly steps cumbersome.

[0007] Third, based on the second point mentioned above, it can be seen that the existing grounding structure requires a large operating space, so the casing is usually designed to be large in size, resulting in a large overall volume of the magnetic power supply, which is not conducive to miniaturization design; and for a small-sized casing, due to its small internal operating space, its installation difficulty is doubled, and usually requires the use of external tools (such as pliers, tweezers or specific tooling), the assembly efficiency is extremely low, which is not conducive to the production of small-sized magnetic power supplies.

[0012] It can be seen from the above that by installing the grounding terminal on the circuit board, when the power supply assembly is installed in the shell, the first through hole on the shell can be more conveniently, accurately and quickly precisely aligned with the first threaded hole on the grounding terminal, so that the first bolt passes through the first through hole and is threadedly connected to the first threaded hole; in addition, during the assembly of the power supply assembly and the shell, there is no need for the user to put his fingers (or use tools) into the shell to position and fix the grounding terminal, and there is no need to additionally set a nut to cooperate with the first bolt for connection, which effectively reduces the difficulty of assembly, simplifies the operation steps, and is also conducive to the miniaturized design and automated production of the magnetic power supply.
