[0002] With the rapid development of technology and the continuous miniaturization and integration of electronic devices, not only are the internal functional structures of electronic devices required to be more complex and precise, but the size and weight of power supplies are also facing greater challenges. Traditional power supply housing designs often occupy a large space, making it difficult to meet the compactness and portability requirements of modern electronic devices. In addition, traditional housing designs have significant shortcomings in terms of positioning accuracy and structural stability, which makes power supply components prone to displacement and damage during installation and use, seriously affecting the reliability and lifespan of the power supply.

[0003] The above shortcomings need to be improved. Summary of the Invention

[0004] To address or alleviate the problem of large size in existing power supplies, this invention provides a compact power supply.

[0005] The technical solution of this utility model is as follows:

[0006] A compact power supply includes a housing, with a connecting portion disposed on the outer side of the housing, the connecting portion extending toward one side of the middle of the housing, and the projection of the connecting portion in the vertical direction being within the projection range of the housing.

[0007] Furthermore, the shell is a cuboid, and the connecting parts are arranged in pairs, with each pair of connecting parts located on opposite sides of the shell.

[0008] Furthermore, the connecting part includes a main body connected to the housing, the top and bottom of the main body being lower than the top and bottom of the housing, and the main body having a connecting hole.

[0009] Furthermore, the housing is made of aluminum alloy.

[0010] Furthermore, the housing includes a bottom shell, the bottom shell having a receiving cavity in which a circuit board is placed, the bottom shell having a top cover for closing the receiving cavity, the bottom shell having a first limiting part for limiting the position of the circuit board, and the top cover having a second limiting part for limiting the position of the circuit board.

[0011] Furthermore, the first limiting part is disposed at the corner of the side wall of the accommodating cavity to support the substrate edge of the circuit board;

[0012] The second limiting part is located near the edge of the upper cover. The second limiting part is columnar, and the bottom of the second limiting part is in contact with the top of the substrate of the circuit board.

[0013] Furthermore, the bottom shell protrudes into the accommodating cavity at the connecting part, and the circuit board is provided with a groove at the corresponding position to engage with the protrusion.

[0025] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution.

[0027] like Figure 1 As shown in the figure, a compact power supply according to one embodiment of the present invention includes a housing 1, a connecting part 104 is provided on the outer side of the housing 1, the connecting part 104 extends to one side of the middle of the housing 1, and the projection of the connecting part 104 in the vertical direction is within the projection range of the housing 1.

[0028] In traditional designs, the connecting portion 104 of the power supply housing 1 protrudes beyond the housing 1, or requires additional external connecting components, resulting in a larger volume. In this embodiment, the connecting portion 104 is more compactly integrated with the housing 1, making the overall power supply structure smaller and adaptable to the trend of miniaturization and integration of electronic devices.

[0029] like Figure 1 As shown, in a preferred embodiment, the housing 1 is a cuboid with rounded corners, and the connecting parts 104 are arranged in pairs, with each pair of connecting parts 104 respectively located on opposite sides of the housing 1.

[0030] In this embodiment, the rectangular housing 1, combined with rounded corners, gives it a relatively regular shape. This facilitates manufacturing, optimizes layout, improves space utilization, and enhances the overall aesthetics and safety of the power supply. Furthermore, the paired connecting portions 104, located on opposite sides of the housing 1, effectively reduce the overall volume of the housing 1 while minimizing the encroachment of the connecting portions 104 on the internal space. This ensures sufficient internal space for the necessary components to be arranged without affecting performance. Simultaneously, the connecting portions 104 enhance the strength of the housing 1 at this location.

[0031] like Figure 1 As shown, in a preferred embodiment, the connecting part 104 includes a main body 105 connected to the housing 1. The top and bottom of the main body 105 are lower than the top and bottom of the housing 1, and a connecting hole 106 is provided on the main body 105. When installing the housing 1, the housing 1 is fixed by fasteners such as screws passing through the connecting hole 106.

[0032] In this embodiment, by distributing the top and bottom of the main body 105 lower than the top and bottom of the housing 1, space is provided for the heads of fasteners (such as screws), ensuring that the power supply remains relatively regular and flat after installation, facilitating the placement of other components and thus improving space utilization. Furthermore, the height difference between the main body 105 and the housing 1 can be engaged with the limiting structure of the power supply mounting location for positioning, ensuring the stability of the housing 1.

[0033] In a preferred embodiment, the housing 1 is made of aluminum alloy.

[0034] Aluminum alloy, as a lightweight and high-strength material, possesses excellent resistance to deformation and impact, enabling the housing 1 to maintain structural integrity and stability when subjected to external pressure or impact, effectively protecting the internal power components from damage. Furthermore, aluminum alloy has good thermal conductivity, quickly and effectively transferring heat generated inside the housing 1 to the external environment, achieving effective heat dissipation, improving the power supply's heat dissipation efficiency, reducing operating temperature, and preventing overheating failures. By optimizing heat dissipation performance, the aluminum alloy housing 1 helps maintain stable power supply operation, improving the overall system reliability and performance. In addition, the relatively low density of aluminum alloy results in a lighter overall weight for the housing 1, achieving lightweight design and meeting the demands of miniaturized, integrated, and portable electronic devices, contributing to reduced overall weight and improved user experience.

[0035] like Figures 2 to 5As shown, in a preferred embodiment, the housing 1 includes a bottom shell 101, which has a receiving cavity in which a circuit board 2 is placed. The bottom shell 101 is provided with a top cover 107 for closing the receiving cavity. The bottom shell 101 is provided with a first limiting part 102 for limiting the position of the circuit board 2, and the top cover 107 is provided with a second limiting part 108 for limiting the position of the circuit board 2.

[0036] The first limiting part 102 is disposed at the corner of the side wall of the accommodating cavity and is used to support the edge of the substrate of the circuit board 2; the second limiting part 108 is close to the edge of the top cover 107, the second limiting part 108 is columnar, and the bottom of the second limiting part 108 contacts the top of the substrate of the circuit board 2.

[0037] In this embodiment, a first limiting part 102 is provided at the corner of the accommodating cavity sidewall of the bottom shell 101, and a second limiting part 108 is provided at the edge of the upper cover 107, thereby achieving dual limiting of the position of the circuit board 2. The first limiting part 102 supports the edge of the substrate of the circuit board 2, preventing it from moving downwards; the second limiting part 108 (columnar structure) contacts the top of the substrate of the circuit board 2, restricting the upward movement of the circuit board 2, so that the circuit board 2 is accurately positioned and stably fixed in the accommodating cavity, reducing the risk of displacement caused by vibration or impact. In addition, the design of the first limiting part 102 and the second limiting part 108 simplifies the installation process of the circuit board 2. During assembly, the circuit board 2 can be easily placed in the predetermined position, improving assembly efficiency and reducing assembly errors caused by human error. Furthermore, the first limiting part 102 is located at the edge of the bottom shell 101, which can reduce the encroachment on the central area and ensure a sufficiently large accommodating space. At the same time, the first limiting part 102 can be used as a reinforcing rib to improve the structural strength of the bottom shell 101.

[0038] like Figure 3 As shown, in a preferred embodiment, the bottom shell 101 protrudes into the cavity at the connecting part 104, and the circuit board 2 is provided with a groove at the corresponding position to engage with the protrusion.

[0039] In this embodiment, the protrusion inside the accommodating cavity engages with the corresponding groove on the circuit board 2, further limiting the circuit board 2. The space utilization rate can be improved by utilizing the position occupied by the connecting part 104, further enhancing the stability of the circuit board 2 inside the housing 1 and preventing displacement or loosening.

[0040] like Figure 2 and Figure 3 As shown, in a preferred embodiment, a first connector 3 is provided at the bottom of the accommodating cavity, which is used to connect the circuit board 2 and the bottom shell 101. Specifically, the first connector 3 is an adhesive.

[0041] A second connector 4 is provided between the top cover 107 and the circuit board 2 to connect the two, and the second connector 4 is filled in the upper edge of the circuit board 2. Specifically, the second connector 4 is glue.

[0042] In this embodiment, by using adhesive as a first connector 3 at the bottom of the accommodating cavity and filling the space between the upper cover 107 and the circuit board 2 with glue as a second connector 4, a tight connection is achieved between the circuit board 2 and the bottom shell 101 and the upper cover 107. The adhesive and glue provide a strong bonding effect, preventing the circuit board 2 from loosening during use and enhancing the structural stability of the entire housing 1. Furthermore, the adhesive and glue connection method facilitates assembly and improves production efficiency. Simultaneously, the glue filling the upper edge of the circuit board 2 also helps improve sealing, preventing the intrusion of harmful substances such as external dust and moisture, thereby extending the power supply's lifespan and improving reliability.

[0043] like Figure 1 and Figure 4 As shown, in a preferred embodiment, the housing 1 is provided with a wiring hole 103, and the circuit board 2 is provided with a pin 201, which extends out of the housing 1 through the wiring hole 103.

[0044] In this embodiment, the wiring hole 103 provided on the housing 1 allows the pins 201 on the circuit board 2 to pass through smoothly, which facilitates the connection between the circuit board 2 and the external circuit, meets the needs of signal transmission and power supply between the power supply and external devices, and ensures the orderly routing.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
