The first side cover 22 is provided with a first guide hole 221. The first terminal 12 passes through the first guide hole 221 and protrudes from the first guide hole 221.

[0032] The first side cover 22 has a first connecting part 222 on the side facing the housing 21. The first connecting part 222 is arranged around the circumferential direction of the housing 20. The housing 21 is fitted and sealed to the first connecting part 222.

[0033] The driving power supply 1 provided in this embodiment is composed of a wiring assembly 10 and a housing 20, thereby improving the sealing performance of the driving power supply 1. Furthermore, the driving power supply 1 provided in this embodiment can also include various other components, and can be applied to multiple electrical device fields, such as lighting equipment, manufacturing equipment, and medical equipment.

[0034] The wiring assembly 10 includes a circuit board 11 and a first terminal block 12. Optionally, the circuit board 11 may include, but is not limited to, a rigid circuit board, a flexible circuit board, or a rigid-flexible composite board, etc., and this embodiment is not limited in this regard. Optionally, the circuit board 11 may include, but is not limited to, a single-layer board, a double-layer board, or a multi-layer board, etc., and this embodiment is not limited in this regard. The first terminal block 12 is disposed on the surface of the circuit board 11 and can be used to fix and support the connecting wires connecting the circuit board 11. It can also be used as an adapter or converter to realize the connection between different circuit boards 11 or devices by adapting to different interfaces. Optionally, the first terminal block 12 is used to connect output lines, input lines, or signal lines, etc.

[0035] The outer casing 20 includes a housing 21 and a first side cover 22. The housing 21 is formed by a plurality of peripheral side plates, which together form a receiving cavity, in which the circuit board 11 is disposed. For example, four peripheral side plates form a rectangular housing 21. The housing 21 also has a first opening communicating with the receiving cavity. The first side cover 22 is disposed at the first opening and connected to the housing 21. The first side cover 22 has a first guide hole 221, which penetrates the first side cover 22 along the arrangement direction of the first side cover 22 and the housing 21, and at least a portion of the first terminal block 12 protrudes to the outside from the first guide hole 221.

[0036] Since the housing 21 is formed by multiple peripheral side plates, the housing 21 can be erected during the potting and aging tests of the drive power supply 1 without the need for fixtures, which simplifies the operation and improves the testing efficiency.

[0037] Optionally, the housing 21 is a one-piece structural component, and optionally, the material of the housing 21 includes aluminum. This embodiment, by making the housing 21 a one-piece all-aluminum body, helps to improve the protective performance of the side covers and wiring terminals.

[0038] The first side cover 22 is provided with a first connecting portion 222, which is arranged around the outer shell 20 in the circumferential direction. The outer shell 20 is sleeved on the first connecting portion 222, and the inner surface of the shell 21 abuts against and connects to the first connecting portion 222. Optionally, the connection method between the first connecting portion 222 and the shell 21 includes, but is not limited to, interference fit, snap-fit, adhesive fit, threaded fit, etc., and this embodiment does not limit this.

[0039] In one embodiment, the first side cover 22 is used as the grounding terminal, and then thermally conductive adhesive is poured into the housing 21 from the opening on the side away from the first side cover 22. The thermally conductive adhesive is used to improve the heat dissipation effect of the drive power supply 1. Since the housing 21 is sleeved and sealed to the first connection part 222, the thermally conductive adhesive provided in the housing 21 can be prevented from leaking out, thereby improving the grounding effectiveness and safety between the drive power supply 1 and the electrical device.

[0040] Therefore, the drive power supply 1 provided in this embodiment has the circuit board 11 inside the housing 20 and the wiring terminals exposed outside the housing 21, which improves the sealing performance of the drive power supply 1, prevents the thermal conductive adhesive inside the housing 21 from leaking out, improves the grounding effectiveness and safety between the drive power supply 1 and the electrical device, simplifies the electrical connection process, enables plug-and-play, greatly shortens the installation time, improves the installation efficiency, expands the applicability of the drive power supply 1, improves the modularity of the drive power supply 1, and can be adapted to electrical devices of various sizes and specifications.

[0041] Furthermore, the housing 21 is fitted onto and connected to the first connecting part 222, which not only ensures the sealing performance of the drive power supply 1, but also facilitates the installation of the housing 20.

[0042] Please refer to this as well. Figures 1-7 In one embodiment, a receiving groove 223 is provided at the connection between the first connecting part 222 and the housing 21.

[0044] Therefore, by providing a sealing ring 31, this embodiment improves the connection performance between the first connecting part 222 and the housing 21, thereby further improving the sealing performance of the housing 20, improving the sealing performance of the drive power supply 1, and improving the grounding effectiveness and safety between the drive power supply 1 and the electrical device.

[0045] Furthermore, by providing the receiving groove 223, this embodiment not only facilitates the positioning of the sealing ring 31 and reduces the assembly difficulty of the sealing ring 31, but also limits the position of the sealing ring 31, thereby improving the reliability of the sealing ring 31 in sealing the first connecting part 222 and the housing 21.

[0046] Please refer to this as well. Figures 1-7 In one embodiment, the first side cover 22 is provided with a first mounting hole 224, which penetrates the first side cover 22 along the thickness direction of the first side cover 22.

[0047] The circuit board 11 is provided with a first mounting hole 111, which is correspondingly provided with the first mounting hole 224. The first mounting hole 111 and the first mounting hole 224 are used to accommodate the first fastener.

Optionally, the number of first mounting holes 224 is at least one, the number of first assembly holes 111 is at least one, and the number of first assembly holes 111 is equal to the number of first mounting holes 224.

[0049] Optionally, the housing 21 is provided with a first mating hole 211, which penetrates the housing 21 along the thickness direction of the housing 21. The first mating hole 211 is correspondingly provided with the first mounting hole 224, and the first mating hole 211 is used to accommodate the first fastener.

[0050] Therefore, this embodiment provides a first mounting hole 224 on the first side cover 22, a first assembly hole 111 on the circuit board 11, and a first fastener to connect the first side cover 22 to the circuit board 11, fix the position of the circuit board 11, and improve the reliability of the drive power supply 1.

The three guide portions 226 are spaced apart along the arrangement direction perpendicular to the first side plate to the outer shell 20, and the circuit board 11 is disposed between any two adjacent guide portions 226.

[0057] Therefore, by providing a guide portion 226 on the first cover plate to guide and limit the position of the circuit board 11 relative to the first cover plate, the first terminal 12 passes through the first guide hole 221, which not only reduces the assembly difficulty of the drive power supply 1, but also improves the reliability of the drive power supply 1.
