[0002] Power supply equipment is a device that provides stable electrical energy to electronic systems. Its core function is to convert other forms of energy into electrical energy and to ensure the normal operation of the equipment through mechanisms such as voltage regulation and current control. Power supply equipment has energy conversion capabilities, which can convert AC power from the power grid into DC power required by the equipment, or provide power directly from batteries.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 1-3As shown, the present invention proposes a power supply device with multiple power supply interfaces, including a housing 1, and a panel 2 is installed on the front end of the housing 1.

[0025] The wiring mechanism includes a terminal block 31 installed on the upper part of the housing 1. The terminal block 31 has a plurality of wiring slots 32, and wiring plugs 33 pass through the side walls of the wiring slots 32.

[0026] The first power supply terminal 41 and the second power supply terminal 42 are arranged side by side at the lower part of the housing 1;

[0027] The interface mechanism includes a plurality of slots 51 formed in the first power supply terminal 41. The rear end of the slots 51 is provided with staggered slots 52. A movable power supply interface 53 is provided between the slots 51 and the slots 52. A protruding limiting member 54 is sleeved on the outside of the power supply interface 53, and a power supply electrode post 55 that cooperates with the power supply is connected to the tail end. A spring member 56 that clamps between the power supply and the power supply interface 53 is sleeved on the outside of the power supply electrode post 55.

[0028] The power supply interface 53 is connected to external electrical equipment via a power cable 6.

[0029] It should be noted that: slot 51 is a "straight" slot, and limiting slot 52 is a "circular" slot. The limiting member 54 first slides along the slot 51 with the "straight" slot, and can be adjusted in direction when it enters the limiting slot 52 with the "circular" slot.

[0030] In this embodiment, a first power supply terminal 41 and a second power supply terminal 42 are provided on the power supply equipment. Both have multiple power supply interfaces. When connecting the power supply equipment to the power supply equipment, the core of the power cable is inserted into the power supply interface 53. The power supply interface 53 is plugged into and fixed with the power cable 6. By pressing, the cable sleeve of the power cable 6 is inserted into the slot 51 opened in the first power supply terminal 41. At this time, under the action of pressing force, the spring 56 is compressed, and the end power supply electrode post 55 is connected to the power supply, becoming a power-conducting structure. Rotating the combination structure of the power cable 6 and the power supply interface 53 drives the limiting member 54 to rotate in the limiting groove 52. At this time, the limiting member 54 is misaligned with the slot 51. The protruding limiting member 54 can act as a limiting structure, leaving part of the power cable 6 in the slot 51. On the one hand, the power cable 6 is covered and protected. On the other hand, the locking of the limiting member 54 can prevent the connection between the two from separating, thus achieving stable power supply.

[0031] It is understandable that when the combined structure of the power supply interface 53 and the power cable 6 is inserted into the inner cavity of the limiting groove 52, it can rotate 90° clockwise and counterclockwise. The end wall of the limiting member 54 and the limiting groove 52 are inclined surfaces. The inclined end surface can reduce the influence of the spring member 56's reset force and reduce the wear on the limiting structure.

[0032] like Figure 3 As shown, the deformation range of the spring 56 is the same as the depth of the power cable 6 inserted into the slot 51. Through the reset deformation of the spring 56, the depth of the power supply post 55 and the power supply is always the same, preventing the power supply post 55 from being connected too deeply, not connected enough, or loose.

[0033] To facilitate heat dissipation of the electrical components inside the housing 1, a heat sink 7 with heat dissipation holes is further installed on the housing 1.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
