[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] See Figures 1 to 2 As shown, a wardrobe cabinet light power supply includes a housing 1 and a drive circuit board 2 disposed within the housing. A power input terminal 3 is provided on one end face of the housing. In this embodiment, the housing is a plastic housing. It is composed of a box and a base plate connected by snap-fit ​​joints. The drive circuit board has a conventional structure from the prior art and is simply applied, therefore it is not described in detail. The power input terminal also has a common structure.

[0020] Furthermore, in this embodiment, an expansion connection groove 4 is provided on the upper part of the side wall of the outer casing, and an expansion connection terminal 5 connected to the drive circuit board is provided in the expansion connection groove. Several output terminals 6 connected to the drive circuit board are provided on the other end face and side face of the outer casing. In this embodiment, the depth of the expansion connection groove can be set as needed, and expansion connections can be achieved in conjunction with the expansion connection terminals, improving the stability and reliability of use. Moreover, a wire clamping piece 7 is provided on the expansion connection groove by screws, and the extension wire is clamped and positioned by the wire clamping piece. This clamping and positioning of the expansion connection terminal can prevent loosening or falling off.

[0021] Furthermore, in practical applications, the end face and side face of the housing are provided with an upper clamping spring 8 and a lower clamping spring 9, which are respectively located at the upper and lower edges of the output terminal. During use, the wire is inserted into the output terminal and clamped and limited by the upper and lower clamping springs. In this embodiment, the upper and lower clamping springs are fixed to the housing with screws, and are arc-shaped plastic structures. The clamping ends of the upper and lower clamping springs are provided with anti-slip teeth; these anti-slip teeth press against the surface of the wire. Through this structure, when the output wire is connected, the upper and lower clamping springs, in conjunction with the anti-slip teeth, can clamp and position the output wire, preventing it from loosening or falling off, thus improving stability and reliability.

[0022] Furthermore, the output terminal 6 includes a terminal socket 61 and a plurality of guide strips 62 integrally formed on the inner wall of the terminal socket. This structure satisfies the requirements for plug-in connection and improves ease of use.
