Technical Field

[0001] The utility model relates to the technical field of power adapters, in particular to a power adapter shell with multiple protections. Background Art

[0002] A power adapter is a power conversion device for small portable electronic devices and electronic appliances. It is generally composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. Its working principle is to convert AC input into DC output. It can be divided into wall-mounted and desktop types according to the connection method.

[0003] After searching, the existing Chinese patent publication number is: CN216290712U, which provides a power adapter housing with multiple protections. This patent uses a heat dissipation port, a fixing plate, a limit plate, a baffle, a screw rod, a knob and a slot in coordination. When the power adapter is in full working order, the heat dissipation port is opened by rotating the knob, which is conducive to the dissipation of heat. The heat dissipation port is blocked by the baffle to prevent dust, thereby solving the problem that the existing power adapter housing has no heat dissipation measures and the heat generated by long-term use will affect the service life of the power adapter.

[0004] Although the above patent can protect the adapter from dust, the above-mentioned multiple protection power adapter shell still has the following problems: the waterproof performance of the power adapter on the market is poor, which makes the components inside the adapter very easy to contact with external water flow, and cannot well protect the internal electronic components to ensure the long-term stable operation of the adapter.

[0005] In view of the above problems, a power adapter housing with multiple protections is proposed. Utility Model Content

[0020] By adopting the above technical solution, by installing the rubber pad, a closed environment can be provided when the power supply port and the charging cable are slidably connected to ensure waterproof performance.

[0021] As a further description of the above technical solution: a charging cable is fixedly connected to the inner wall of the rubber pad.

[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1 and Figure 2 The utility model discloses a multi-protection power adapter shell, comprising a shell 1, the front and rear sides of the shell 1 are rotatably connected with a rotating rod 18, the waterproof component can be rotated by installing the rotating rod 18, the inner wall of the torsion spring 12 is sleeved with a connecting rod 13, and the connecting rod 13 is fixedly connected to the shell 1, and the required elastic component can be carried by the installed connecting rod 13, a spring groove 9 is opened near the middle of the shell 1, both sides of the top front side of the shell 1 are fixedly connected with rubber baffles 17, and the installed rubber baffles 17 can effectively prevent water from entering the interior of the power adapter, a power supply port 2 is opened in the middle of the right side of the shell 1, the inner wall of the power supply port 2 is slidably connected with a rubber pad 3, and the inner wall of the rubber pad 3 is fixedly connected with a charging cable 4.

[0033] Reference Figure 1 and Figure 2 The outer ring of the rotating rod 18 is fixedly connected to a baffle 5, and a limiting block 6 is fixedly connected to the middle of the bottom of the baffle 5. One end of a torsion spring 12 is fixedly connected to the bottom of the baffle 5, and the other end of the torsion spring 12 is fixedly connected to the shell 1. The inner wall of the spring groove 9 is fixedly connected to one end of a spring 10, and the other end of the spring 10 is fixedly connected to a cylindrical button 7, and the cylindrical button 7 is slidably connected to the shell 1. A slider 11 is fixedly connected to one side of the cylindrical button 7, and the slider 11 is slidably connected to the shell 1. The right side of the slider 11 is fixedly connected to a limiting buckle 8. A heat dissipation component is provided on the front side of the interior of the shell 1. Through the linkage between the limiting buckle 8, the limiting block 6, the baffle 5, the torsion spring 12, the cylindrical button 7, the slider 11 and the spring 10, water can be effectively prevented from entering the interior of the adapter to improve its reliability and safety in a humid environment.

[0034] Reference Figure 3The heat dissipation component includes a heat dissipation cavity 14, which is opened inside the shell 1. By installing the heat dissipation cavity 14, the heat inside the power adapter can be well dissipated, and at the same time, a ventilation environment is provided to greatly improve the heat dissipation efficiency. A heat dissipation fan 16 is fixedly connected to the middle of the inner wall of the heat dissipation cavity 14.
