[0024] The following is combined with Figure 1-5 To further explain this application,

[0025] An embodiment of the present application discloses a power adapter with a detachable plug, including a power adapter body 1 and a plug connecting seat 2. A storage seat 3 is fixedly installed on the front of the power adapter body 1, and square holes 4 are opened on both sides of the storage seat 3. A U-shaped clamping plate 5 is movably installed inside the square hole 4, and an arc-shaped abutment plate 6 is fixedly installed on the inner walls of both sides of the U-shaped clamping plate 5. Abutment blocks 7 are fixedly installed on both sides of the plug connecting seat 2, and a baffle 8 is threadedly connected to the top of the U-shaped clamping plate 5. A positioning pin 9 is fixedly installed in the middle part of the top of the storage seat 3, and a reset spring 10 is sleeved on the surface of the positioning pin 9 and located at the bottom of the baffle 8.

[0026] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 Through the mutual cooperation of the plug connecting seat 2, the storage seat 3, the U-shaped card plate 5, the arc-shaped abutment plate 6, the abutment block 7, the baffle 8, the positioning pin 9, and the return spring 10, the function of quick disassembly and assembly of the plug is realized, so that the corresponding plug can be installed according to different sockets, thereby achieving the purpose of increasing the flexibility of the power adapter, and the modular design means that when the plug is damaged, only the plug module needs to be replaced.

[0027] A plurality of first contacts 11 are fixedly mounted on the front of the receiving seat 3 , and a first insulating pad 12 is fixedly mounted on the front of the receiving seat 3 and outside the first contacts 11 .

[0028] Reference Figure 2 and Figure 5 The first insulating pad 12 cooperates with the second insulating pad 14 to achieve the function of current isolation, thereby avoiding electric shock and external environmental interference, thereby ensuring stable power transmission.

[0029] A plurality of second contacts 13 are fixedly mounted on the back of the plug connector 2 , and the second contacts 13 match the first contacts 11 . A second insulating pad 14 is fixedly mounted on the back of the plug connector 2 and outside the second contacts 13 .

[0030] Reference Figure 4 and Figure 5 The second contact 11 cooperates with the first contact 13 to realize the function of power transmission, thereby ensuring that the power of the conductive plug 21 is stably transmitted to the power adapter body 1.

[0031] T-shaped slots 15 are provided on the inner walls of the upper and lower sides of the receiving seat 3 , and T-shaped blocks 16 are fixedly installed in the middle parts of the upper and lower sides of the plug connecting seat 2 .

[0032] Reference Figure 2 and Figure 4 The T-shaped slot 15 and the T-shaped block 16 facilitate ensuring the stability of the plug connector 2 during installation and use, further ensuring the stability of power transmission.

[0033] The top of the positioning pin 9 is threadedly connected to the limit block 17 , and a T-shaped through hole 18 is opened in the middle part of the top of the baffle 8 , and the diameter of the small end of the T-shaped through hole 18 is adapted to the size of the positioning pin 9 .

[0034] Reference Figure 2 and Figure 5 The baffle 8 is easily limited by the limiting block 17, thereby ensuring effective control of the tension of the return spring 10.

[0035] A handle 19 is provided in the middle of the U-shaped clamping plate 5 , and a wire 20 is fixedly mounted on the bottom of the power adapter body 1 .

[0036] Reference Figure 1 and Figure 3 The handle 19 allows the user to quickly adjust the working state of the U-shaped card plate 5, thereby achieving the purpose of quickly releasing the plug connector 2.

[0037] A plurality of conductive pins 21 are fixedly mounted on the front of the plug connector 2 .

[0038] Reference Figure 1and Figure 5 The conductive plug 21 is easily inserted into the socket to achieve power transmission to meet the working requirements of the power adapter.

[0039] Working principle: When using this device, the U-shaped card plate 5 is pulled downward by the handle 19, and the arc-shaped plate 6 is driven to descend synchronously by the U-shaped card plate 5. At the same time, the baffle 8 is driven to move by the U-shaped card plate 5. When the U-shaped card plate 5 moves on the surface of the positioning pin 9, the reset spring 10 is compressed, and the T-shaped block 16 is limited by the T-shaped slide groove 15. After the plug connection seat 2 that is compatible with the socket is placed inside the storage seat 3, the handle 19 is released, and the reset spring 10 releases the tension synchronously, pushing the baffle 8 to rise, and the U-shaped card plate 5 is driven to rise by the baffle 8, and the arc-shaped plate 8 is driven by the U-shaped card plate 5. The support plate 6 rises synchronously, during which the support block 7 is gradually compressed by the arc surface of the arc-shaped support plate 6, and the force is transmitted to the plug connector 2 through the support block 7, driving the plug connector 2 to fit the power adapter body 1. As the plug connector 2 moves initially, the first contact 11 contacts the second contact 13, and the first contact 11 and the second contact 13 are isolated from the external environment by the first insulating pad 12 and the second insulating pad 14, completing the installation. When removing the plug, the arc-shaped support plate 6 is separated from the support block 7 by only pulling the U-shaped card plate 5 downward by the handle 19, and the plug can be taken out.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
