Description

Technical Field

[0001] The utility model relates to the technical field of power supply shells, in particular to a semi-glue-filled power supply shell assembled with a sheet metal upper cover. Background Art

[0002] The power supply shell is an important part of the power supply equipment. It not only protects the electronic components inside the power supply, but also involves the heat dissipation, appearance and structural stability of the power supply. The semi-potted power supply shell is a half or part of the power supply shell filled or encapsulated with special colloid materials to protect the electronic components inside the power supply, improve the heat dissipation performance of the power supply, and enhance the mechanical strength and impact resistance of the power supply.

[0003] like Figure 1 As shown, the bending and assembly method of most semi-potted power supply covers on the market is: the cover is bent all around and fixed to the bottom shell by adding threads to the two symmetrical bending surfaces. The thin shell will cause the other two end bending surfaces to be unable to support well. If threading fixing holes are added to this bending surface, it will not be affected by the force in the bending direction and will cause deformation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the defect in the prior art that the threading hole added to the bending surface of the upper cover end is not easily deformed by the force in the bending direction, and to provide a semi-potted power supply housing assembled with a sheet metal upper cover.

[0005] The utility model adopts the following technical solution to solve its technical problems: a semi-potted power supply shell assembled with a sheet metal upper cover, comprising a lower shell and an upper cover, wherein the upper cover is a shell structure formed by folding a sheet metal plate to form a bottom opening, end bending lines and side bending lines are respectively arranged at both ends and both side edges of the sheet metal plate, an avoidance groove is provided at the intersection of the bending lines and the side bending lines, and the end plate and side plate of the upper cover are flipped to a vertical state along the end bending lines and the side bending lines, U-shaped notches are provided at both ends of the side plate, and both ends of the end plate have overlapping edges overlapping the side plates, a hollow boss is protruded from the overlapping edges, the center line of the hollow boss is in the same straight line with the bending axis of the U-shaped notch, and a threaded hole corresponding to the center hole of the hollow boss is provided on the upper part of the side wall of the lower shell.

[0006] Furthermore, the height of the end plate is greater than that of the side plate, and a notch is provided on the end plate near the overlapped edge. Setting the height of the end plate greater than that of the side plate increases the strength of the end plate; providing the notch reduces local stress concentration.

[0007] Furthermore, the upper portion of the inner side wall of the lower shell is thinned to form a connecting edge, and the bottom end of the inner side wall of the connecting edge forms a step surface supporting the side plate. The step surface supports the side plate, and its connecting edge is connected to the side plate and the end plate at the same time to ensure the effectiveness of the connection.

[0008] Furthermore, the threaded hole is provided on the connecting edge, which is convenient to provide and easy to implement.

[0009] Furthermore, an internal thread is provided on the inner wall of the hollow boss.

[0010] Furthermore, the end plate is provided with a mounting hole, a wire mounting ring is installed in the mounting hole, and a wire lead-out hole is provided on the wire mounting ring. The wire lead-out is facilitated by providing the wire mounting ring.

[0011] Furthermore, the wire installation ring is made of silicone or rubber, which can protect the wire.

[0012] Furthermore, the upper cover is provided with multiple rows of waist-shaped heat dissipation holes at the front and rear sections to help the power supply dissipate heat.

[0013] Furthermore, the lower housing is a U-shaped profile, and a plurality of heat dissipation strips are arranged on the outer side of the side wall. The profile ensures the rigidity and strength of the lower housing, and the heat dissipation strips ensure the heat dissipation performance of the power supply.

[0014] The beneficial effects of the utility model are as follows: compared with the upper cover of the prior art, the utility model increases the length of the end plate, and forms a connecting structure at the overlap of the end plate and the side plate to connect with the lower shell body, thereby increasing the strength, and the threading and fixing holes opened on the end plate are not subject to the force in the bending direction and will not deform; at the same time, the sheet metal plate of the upper cover only has the loss of process notches, thereby saving costs.

[0025] The present invention is now further described in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] like Figure 2 and Figure 3 As shown, a semi-potted power supply housing assembled with a sheet metal upper cover comprises a lower housing 1 and an upper cover 2, wherein the upper cover 2 is a housing structure formed by folding a sheet metal plate 20 to form a bottom opening. The lower housing 1 is a U-shaped profile, and a plurality of heat dissipation strips are arranged on the outer side of its side wall. The upper cover 2 is provided with multiple rows of waist-shaped heat dissipation holes 23 at the front and rear sections, and the height of the end plate 21 is greater than that of the side plate 22. The end plate 21 is provided with a mounting hole 210, and a wire mounting ring 3 is installed in the mounting hole 210, and a lead-out hole for the wire 4 is provided on the wire mounting ring 3. The material of the wire mounting ring 3 is preferably silicone or rubber.

[0027] like Figures 4 to 7 As shown, U-shaped notches 221 are provided at both ends of the side plate 22, and overlapping edges 211 overlapped with the side plate 22 are provided at both ends of the end plate 21. A hollow boss 212 is formed protruding from the overlapping edge 211, and an internal thread is provided on the inner wall of the hollow boss 212. The center line of the hollow boss 212 is in the same straight line as the bending axis of the U-shaped notch 221. A notch 213 is provided on the end plate 21 near the overlapping edge 211. The upper thickness of the inner side wall of the lower shell 1 is thinned to form a connecting edge 11, and a step surface 111 supporting the side plate 22 is formed at the bottom end of the inner side wall of the connecting edge 11. A threaded hole 112 is provided on the connecting edge 11, and the screw 5 is passed through the threaded hole 112 and the center hole of the hollow boss 212 in sequence to achieve the connection between the upper cover 2 and the lower shell 1.

The end plate 21 and the side plate 22 of the upper cover 2 are flipped to a vertical state along the end bending line 201 and the side bending line 202, and the overlapping edge 211 is folded and extended into the inner side of the side plate 22, while ensuring that the center line of the hollow boss 212 and the bending axis of the U-shaped notch 221 are in the same straight line.

[0029] The sheet metal plate 20 of the upper cover 2 only has the loss of process notches, which makes more reasonable use of the material size and reduces the loss of raw materials. The upper cover 2 and the lower shell 1 are installed more stably, alternately overlapped, and the strength is greater than the conventional bending form. The threading hole of the upper cover 2 is subjected to greater force than the conventional bending installation method.
