Description

Technical Field

[0001] The utility model relates to the technical field of power adapters, and particularly relates to an auxiliary fixing structure for a power adapter connector. Background Art

[0002] A power adapter, also known as an external power supply, is a power supply conversion device for small portable electronic devices and electronic appliances. A power adapter generally consists of components such as a housing, 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 converts the alternating current from a power socket or other power source into the direct current required by the device, thereby providing power for the device, not necessarily charging the device. Its output voltage is usually the direct current required by the device. In appearance, it is relatively small and light, and sometimes has a detachable plug, which is convenient for carrying and replacement. It is suitable for various electronic devices and is widely used in devices such as security cameras, set-top boxes, routers, light strips, and massagers, and is commonly found on small electronic products such as mobile phones, liquid crystal displays, and laptop computers.

[0003] During the use of the existing power adapter, after being inserted into the socket to connect the power supply, it is prone to loosen and fall off, resulting in abnormal operation. Moreover, when the power adapter is connected to the socket, it is prone to short-circuit phenomena, reducing the service life of the power adapter. In addition, during the use of the existing power adapter, it cannot be fixedly connected to the connector, resulting in the loosening of the connector and reducing the working efficiency of the power adapter.

[0004] The existing patent (publication number: CN217642015U) discloses a power adapter with a fixed and anti-loosening connector, including a power adapter body and a connector. The connector is inserted and installed on the left side of the power adapter body, and the right end of the connector is embedded in the interior of the power adapter body. A power cord is connected to the left side of the connector. A power plug is provided on the bottom surface of the power adapter body. Through the setting of the inclined protrusion, the inclined protrusion penetrates through the right surface of the connector and the left surface of the power adapter body, and the inclined protrusion and the card slot inside the power adapter body form a snap structure, which is convenient for fixedly connecting the connector to the power adapter body to avoid loosening. Moreover, a button is connected above the inclined protrusion, and the button penetrates through the upper surface of the connector. By using the rebound effect of the return spring, it is convenient to quickly disassemble and assemble the connector, and it has good practicability.

[0005] Regarding the above problems, existing patents have provided solutions. However, existing power adapters usually lack an auxiliary fixing structure for the three-pin connecting plug used for power connection, so it is easy to cause detachment after the three-pin connecting plug is inserted into the three-pin socket of the power adapter, which is not stable enough. And existing power adapters usually lack a protective structure, so there is a hidden danger that the power adapter may fall and be damaged, thus improvement is needed.

[0006] Therefore, an auxiliary fixing structure for the connector of a power adapter is proposed. Utility Model Content

The side of the inner wall of the fixing block 405 close to the three-pin connector 3 contacts the three-pin connector 3.

[0030] In this embodiment: By providing a power adapter body 1, a three-pin socket 2, a three-pin connector 3, an auxiliary fixing component 4, and a protection component 5, during use, by inserting the three-pin connector 3 of the power connection line into the three-pin socket 2 of the power adapter body 1, the power adapter body 1 is connected to the power supply. Through the setting of the auxiliary fixing component 4, the position of the three-pin connector 3 can be fixed, preventing the three-pin connector 3 from falling out of the three-pin socket 2, thereby improving the stability of the connection between the power adapter body 1 and the power supply. Through the setting of the protection component 5, the power adapter body 1 can be protected, effectively preventing the power adapter body 1 from being damaged due to dropping, thereby improving safety.

[0031] Specifically, as Figure 1 , Figure 2 , Figure 5 shown, the protection component 5 includes an L-shaped protection plate 501. A buffer spring 502 is provided inside the L-shaped protection plate 501, and fixing rings 503 are fixedly connected to both ends of the buffer spring 502.

[0032] Specifically, as Figure 1 , Figure 2 , Figure 5 shown, the fixing rings 503 are fixedly connected to the L-shaped protection plate 501 and the power adapter body 1 respectively on the sides close to the L-shaped protection plate 501 and the power adapter body 1.

[0033] Specifically, as Figure 1 , Figure 2 , Figure 5 shown, the number of buffer springs 502 is several, and they are evenly distributed inside the L-shaped protection plate 501.

[0034] In this embodiment: By providing the L-shaped protection plate 501, the buffer spring 502, and the fixing ring 503, when the power adapter body 1 drops, the L-shaped protection plate 501 can protect the power adapter body 1, preventing the outer shell of the power adapter body 1 from being damaged. The buffer spring 502 can buffer the impact force generated by gravity during dropping, preventing the internal components of the power adapter body 1 from being damaged due to impact vibration. Through the setting of the fixing ring 503, the buffer spring 502 can be connected to the power adapter body 1 and the L-shaped protection plate 501 respectively.

[0035] Specifically, as Figure 1 , Figure 3 , Figure 5 shown, a guide rod 6 is fixedly connected to the rear side of the fixing block 405 close to the support block 401, and the side of the guide rod 6 away from the fixing block 405 penetrates through the support block 401.

[0036] Specifically, as Figure 5As shown in the figure, a sliding hole 7 for cooperating with the guide rod 6 is formed at the rear side of the support block 401 near one side of the fixed clamping block 405, and the surface of the guide rod 6 is slidably connected to the inner wall of the sliding hole 7.

[0037] In this embodiment: Through the arrangement of the guide rod 6, the movement of the fixed clamping block 405 can be guided, and the fixed clamping block 405 will not shake. Through the arrangement of the sliding hole 7, the guide rod 6 can slide in the inner cavity of the support block 401.

[0038] Specifically, as Figure 1 、 Figure 2 shown, a handle 8 is arranged on the top of the power adapter body 1, and the front side and the rear side of the bottom of the handle 8 are rotatably connected to the top of the power adapter body 1 through a rotating shaft.

[0039] Specifically, as Figure 1 、 Figure 2 shown, a grip sleeve 9 is sleeved on the surface of the handle 8, and anti-slip patterns are arranged on the surface of the grip sleeve 9.

[0040] In this embodiment: By arranging the handle 8, it is convenient to pick up and place the power adapter body 1. Through the arrangement of the grip sleeve 9, an anti-slip effect can be achieved.

[0041] Working principle: When in use, by inserting the three-pin connector 3 of the power connection wire into the three-pin socket 2 of the power adapter body 1, the power adapter body 1 is connected to the power supply. Then, rotate the two twisting rings 402 to drive the threaded rod 403 to rotate and move through the thread. The threaded rod 403 rotates through a bearing in the support sleeve 404 and drives the fixed clamping block 405 to move through the support sleeve 404. When the fixed clamping block 405 moves, it drives the guide rod 6 to slide in the sliding hole 7. The guide rod 6 can guide the fixed clamping block 405 to prevent the fixed clamping block 405 from shaking. Then, the three-pin connector 3 is clamped from both sides by the two fixed clamping blocks 405, so as to fix the position of the three-pin connector 3 and prevent the three-pin connector 3 from falling out of the three-pin socket 2, thereby improving the stability of the connection between the power adapter body 1 and the power supply. When the power adapter body 1 falls, the L-shaped protection plate 501 can protect the power adapter body 1 to prevent the outer shell of the power adapter body 1 from being damaged. The buffer spring 502 can buffer the impact force generated by gravity during the fall, and can prevent the internal components of the power adapter body 1 from being damaged due to impact vibration, thereby improving the safety.

[0042] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
