[0001] The utility model relates to the technical field of power adapter output connectors, in particular to an output connector for a power adapter. Background Art

[0002] A power adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is mainly composed of components such as a casing, a transformer, an inductor, a capacitor, a control IC, and a PCB board. It converts AC input into DC output to provide stable power for various electronic devices. When in use, the input plug of the electronic device needs to be inserted into the output connector of the power adapter to provide power to the electronic device.

[0003] Currently, most power adapter output connectors are directly installed on the surface of the power adapter. However, when not in use, the output connector is exposed to the air, and dust may enter the output connector, resulting in poor contact of the output connector during use, making it inconvenient to use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.

[0019] The utility model provides a technical solution: such as Figure 1 - Figure 3As shown in the figure, in this embodiment, an output connector for a power adapter includes a power adapter body 1. A protective cover 2 is provided on one side of the power adapter body 1. A sliding groove 7 is formed inside the protective cover 2. A dust cover 5 is slidably connected to the inner wall of the sliding groove 7. One side of the inner wall of the sliding groove 7 is fixedly connected with a plurality of return springs 6. One end of each of the plurality of return springs 6 is fixedly connected to one side of the dust cover 5. An output connector body 3 is arranged inside the protective cover 2. Through the structural design of the return spring 6 and the dust cover 5, when the output connector body 3 is not in use, the reaction force of the return spring 6 can push the dust cover 5 downward, making the rubber pad two 14 fit with the rubber pad one 10, preventing dust from entering the output connector body 3 and causing poor contact of the output connector body 3. When using the output connector body 3, insert the wiring into the output connector body 3, and the return spring 6 will push the dust cover 5 downward to fix the wiring and prevent the wiring from falling off inside the output connector body 3.

[0020] As Figure 1 - Figure 3 shown, one side of the protective cover 2 is rotatably connected with a connecting frame 4. One side of the connecting frame 4 is fixedly connected with one side of the power adapter body 1. One side of the outer surface of the protective cover 2 is fixedly connected with a lever plate 9. When the output connector body 3 is damaged and needs to be replaced after long-term use, pull the lever plate 9 to rotate the protective cover 2 by 90 degrees, and then replace the output connector body 3. This structure facilitates the replacement of the output connector body 3.

[0021] As Figure 2 and Figure 3 shown, a second catch 13 is fixedly connected to the inner wall of the protective cover 2. A first catch 12 is clamped on one side of the second catch 13. One side of the first catch 12 is fixedly connected with one side of the power adapter body 1. Through the structural design of the second catch 13 and the first catch 12, the protective cover 2 can be fixed to prevent gaps between the protective cover 2 and the power adapter body 1, allowing dust to enter the output connector body 3.

[0022] As Figure 1 and Figure 2 shown, a plurality of fixing bolts 11 are threadedly connected to the outer surface of the output connector body 3. One end of each of the plurality of fixing bolts 11 is threadedly connected to one side of the power adapter body 1. Through the structural design of the fixing bolts 11, the output connector body 3 can be installed on the power adapter body 1, and one side of the output connector body 3 is electrically connected to the output end of the power adapter body 1.

[0023] As Figure 1 and Figure 2 shown, a power cord 8 is fixedly connected to the other side of the power adapter body 1. Through the power cord 8, the input of alternating current can be converted into the output of direct current to provide stable electric energy for electronic devices.

[0024] like Figure 1 - Figure 3 As shown, a rubber pad 10 is fixedly connected to one side of the inner wall of the protective cover 2, and a rubber pad 2 14 is fixedly connected to one side of the dust cover 5. Through the structural design of the rubber pad 10 and the rubber pad 2 14, when the rubber pad 10 and the rubber pad 2 14 are in contact with each other, the sealing between the dust cover 5 and the protective cover 2 can be improved to prevent dust from entering the protective cover 2.

[0025] The utility model provides an output connector for a power adapter, and the specific working principle is as follows:

[0026] When using the power adapter, first pull the dust cover 5 upwards and insert the wiring plug into the output connector body 3. When the dust cover 5 is loosened, the reaction force of the return spring 6 presses the dust cover 5 downward, thereby fixing the wiring plug. When the output connector body 3 is not in use, the reaction force of the return spring 6 pushes the dust cover 5 downward, and the rubber pad 2 14 fits with the rubber pad 1 10 to prevent dust from entering the output connector body 3. When the output connector body 3 is used for a long time, the output connector body 3 has poor contact. Pull the pull plate 9 to rotate the protective cover 2 90 degrees, use a tool to remove the fixing bolts 11 on the output connector body 3, and then install the new output connector body 3 to complete the replacement.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
