DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] See also Figure 3 , a power connector convenient for plugging in is shown in the figure, comprising an electrical appliance 1, a protective housing 2 and a power socket body 13 are arranged on one side of the electrical appliance 1, the power socket body 13 is arranged on the inner wall of the protective housing 2, a power cord connector body 3 is plugged into the inner wall of the power socket body 13, and the power cord connector body 3 is connected to the power socket body 13 through a connecting structure;

[0024] The connection structure includes a guide ring 4 arranged on the outer wall of the power socket body 13, the outer wall of the guide ring 4 is sleeved with a second spring 8, an insulator 10 is arranged at one end of the second spring 8 away from the power socket body 13, a connecting ring 11 is fixedly installed on the inner wall of the insulator 10, the connecting ring 11 is fixedly installed on the outer wall of the power cord connector body 3, and a fixing component is arranged on the outer wall of the insulator 10.

[0025] In the present embodiment: by setting up a connection structure, when the power cord connector body 3 is connected to the power socket body 13, the insulator 10 can be brought into contact with the fixed block 7 through the rebound of the second spring 8, thereby fixing the power cord connector body 3 to the corresponding position, so that the power cord connector body 3 and the power socket body 13 are accurately connected, avoiding multiple inspections relying on manual judgment to ensure that the connector is plugged in and installed, reducing the safety hazards caused by incomplete installation, facilitating the plugging of the power connector, and improving the convenience and safety of the power connector.

[0026] See also Figure 4 and Figure 5 In the figure, the fixing component includes a groove opened on the outer wall of the insulator 10 near the protective shell 2, the cross-section of the groove is L-shaped, a fixing block 16 is fixedly installed on the inner wall of the protective shell 2, a connecting block 15 is fixedly installed on the side of the fixing block 16 near the insulator 10, a limiting block 5 is arranged inside the connecting block 15, a fixing block 7 is fixedly installed on the side of the limiting block 5 near the insulator 10, and an ejection component is arranged on one side of the fixing block 7.

[0027] In the present embodiment: by setting a fixing component, when the power cord connector body 3 is inserted into the power socket body 13, the elastic force generated by the compression and rebound of the second spring 8 pushes the insulator 10 to contact the fixed block 7, and the fixed block 7 limits and fixes the insulator 10, thereby solving the risk of the power socket body 13 and the power cord connector body 3 loosening or even disconnecting after connection, and improving the stability and safety of the connection.

[0028] Working principle: when it is necessary to supply power to the electrical appliance 1, the staff holds the insulator 10 and inserts it into the power socket body 13. During the insertion of the insulator 10, the limiting ball 12 and the guide ring 4 make rolling contact to ensure that the insulator 10 smoothly enters the power socket body 13 and provides a guiding function so that the power cord connector body 3 and the power socket body 13 are coaxially plugged. During the insertion of the insulator 10, the insulator 10 pushes the limiting block 5 and the first spring 6 in the connecting block 15 in turn, thereby compressing the first spring 6. The insulator 10 continues to be inserted and compresses the second spring 8. When the insulator 10 is pushed to the limit position, the staff releases the insulator 10, and the second spring 8 begins to rebound due to the previous compression. The second spring 8 pushes the insulator 10, so that the insulator 10 is embedded in the groove of the fixed block 7. The protruding part of the groove of the insulator 10 is engaged with the slot of the fixed block 7, thereby completing the connection between the power cord connector body 3 and the power socket body 13.

[0029] When it is necessary to disconnect the power supply to the electrical appliance 1, the staff holds the insulator 10 and pushes it forward, so that the protruding part of the groove of the insulator 10 leaves the slot of the fixed block 7. During this process, the anti-slip pad ring 9 is pressed at the same time to push the pushing ring 14 to contact the insulator 10, and the pushing ring 14 lifts the fixed block 7 through the inclined surface of the fixed block 7. The fixed block 7 again squeezes the first spring 6 through the limit block 5, thereby pushing the insulator 10 to the extreme position. The staff then pulls it outward to make the power cord connector body 3 leave the power socket body 13, and the first spring 6 is compressed and rebounds to the initial position. When the power cord connector body 3 completely leaves the protective shell 2, the power connector is disconnected and the electrical appliance 1 is powered off. Example

[0030] See also Figure 4 This embodiment further illustrates Example 1. The ejection assembly includes a push ring 14 disposed on one side of the fixed block 7. The outer wall of the push ring 14 is fixedly sleeved with an anti-slip ring 9.

[0031] In this embodiment: by setting up an ejection component, the anti-skid pad ring 9 is pushed, and the anti-skid pad ring 9 drives the push ring 14 to contact the insulator 10, and ejects the fixed block 7 during the ejection and plugging process, so that the outer wall of the fixed block 7 is movably connected to the bottom end of the insulator 10, thereby realizing the rapid separation of the device.

[0032] See also Figure 2 and Figure 3 In the figure, limiting balls 12 are evenly arranged on the front side of the inner wall of the insulator 10.

[0033] In the present embodiment: by evenly arranging the limiting balls 12, when the power cord connector body 3 is tilted during the insertion of the power socket body 13, the limiting balls 12 and the guide ring 4 roll in contact, so that the power cord connector body 3 is coaxial with the power socket body 13 when inserted, thereby reducing the damage to the power socket body 13 caused by the tilt of the power cord connector body 3 and improving the service life of the device. Example

[0034] See also Figure 4 and Figure 5 In the figure, a first spring 6 is provided on one side of the limiting block 5 close to the fixing block 16 .

[0035] In this embodiment: by setting the first spring 6, when the insulator 10 is inserted, the fixed block 7 pushes the first spring 6 to compress upward, and when the insulator 10 is released, the first spring 6 rebounds quickly to push the fixed block 7 to be inserted into the groove of the insulator 10, thereby avoiding the fixing failure caused by the fixed block 7 not quickly reaching the set position and the insulator 10 not contacting the fixed block 7, thereby improving the reliability of the device.

[0036] See also Figure 4 and Figure 5 In the figure, the side of the fixed block 7 close to the pushing ring 14 is set as an inclined surface.

[0037] In the present embodiment, one side of the fixed block 7 is set as an inclined surface. In the process of pushing the pushing ring 14, the inclined surface can better contact with the pushing ring 14 and make the fixed block 7 rise, thereby avoiding the jamming caused by the contact between the two planes and improving the reliability of the device.

[0038] See also Figure 4 and Figure 5 In the figure, a slot is provided on the side of the fixed block 7 close to the second spring 8, and the cross section of the insulator 10 close to the side of the fixed block 7 is conical.

[0039] In the present embodiment, by setting the cross-section of the slot and one side of the insulator 10 to be conical, the insulator 10 can be better inserted into the slot of the fixed block 7 when the second spring 8 rebounds and engages with the fixed block 7, thereby avoiding the fixed block 7 being unable to return to the set position due to the height difference between the insulator 10 and the fixed block 7, causing the fixed block 7 and the insulator 10 to be stuck, thereby improving the reliability of the device.
