The above-mentioned known The problem is becoming more and more serious, and an improved design solution is needed.

Utility model content

Therefore, the main purpose of the present invention is to provide an improved structure to improve the congestion problem inside the power supply, and at the same time change the air flow inside the power supply to improve heat dissipation efficiency.

The utility model relates to a plug-in structure of a computer power supply, which is a structure in which a power supply unit is connected to an external power supply, wherein the power supply unit is formed by a top plate, a bottom plate and a plurality of side plates, and is used to shield the internal power supply. A conversion circuit, and one of the top plate, the bottom plate, or a plurality of side plates protrudes outwardly from a power connection portion, the power connection portion has at least one plane, and the plane is recessed with an electrical connection groove inward, and the electrical connection groove has a plurality of The connection terminal can be connected with the external power supply, and there is a space for the line to pass through in the power supply connection part, so that the electrical connection groove can be electrically connected with the power conversion circuit. The closing unit controls the conduction or disconnection between the electrical connection slot and the power conversion circuit; the above-mentioned structure enables the power supply to obtain power and work, and can solve the problem that the electrical connection slot occupies the internal space of the power supply, and The opening and closing unit can be accommodated so that components with high current bearing capacity can be used, so that the space inside the power supply is increased, the heat dissipation air flow is smooth, and the electrical connection slot can be set at a convenient position for users to plug and unplug To solve the problems of insufficient current tolerance and volume increase of the known utility model as the output power increases.

Detailed ways

Referring to Fig. 2 and Fig. 3, this figure shows the structure of the utility model, the power supply 1 includes a housing formed by a bottom plate 11, a top plate 12 and a plurality of side plates 13 and the electric power shielded in the housing. A conversion circuit, the bottom plate 11 is equipped with a fan 16 and the side plate 13 is provided with a honeycomb heat dissipation hole 131 and a strip heat dissipation hole 132, and the side plate 13 protrudes outward from the power connection part 2, and the power connection part 2 has at least A plane 21, wherein the plane 21 and the side plate 13 have a non-perpendicular angle, the plane 21 is recessed with an electrical connection groove 14 inwardly, and the opening of the electrical connection groove 14 is connected to the direction of the external power supply and the electrical connection is set The side plates 13 of the groove 14 are parallel, and the electrical connection groove 14 is provided with a plurality of connection terminals 141 for connecting with the external power supply, and there is a space for the line to pass through in the power supply connection part 2, so that the electrical connection groove 14 and the power supply The power conversion circuit in the supplier 1 is electrically connected to provide power for the power supply 1 to work, and the power connection part 2 is also provided with an opening and closing unit 15 at the other end, and the opening and closing unit 15 can control the electrical connection slot 14 and the line between the power conversion circuit is turned on or off, so the electrical connection groove 14 on the power connection part 2 and the opening and closing unit 15 form a power supply structure for the power supply 1 to connect to external power; The part 2 protrudes from the outside of the housing of the power supply 1 , so that the internal space can be vacated to facilitate the arrangement of electronic components, and the internal space is less crowded, which facilitates air circulation and improves heat dissipation efficiency.

With reference to Fig. 4, shown in Fig. 4 is embodiment of the present utility model.
