[0029] Reference below Figure 1-Figure 3The anti-dropping AC power cord plug structure according to the embodiment of the utility model is described.

[0030] like Figure 1-Figure 3 As shown, the anti-drop AC power cord plug structure includes a cable 300, one end of the cable 300 is connected to the plug 200, and the plug 200 is connected to the electrical device socket 100. The plug 200 includes a connecting portion 210 and a plug-in portion 220, one end of the connecting portion 210 is connected to the cable 300, and the other end is connected to the plug-in portion 220, and a step structure is provided at the connection between the plug-in portion 220 and the connecting portion 210, and the cross-sectional area of ​​the plug-in portion 220 is smaller than the cross-sectional area of ​​the connecting portion 210. Specifically, the step structure formed between the plug-in portion 220 and the connecting portion 210 can play a certain limiting role. When the plug-in portion 220 is fully plugged into the electrical device socket 100, the step structure of the plug-in portion 220 and the connecting portion 210 will abut against the surface of the electrical device socket 100, and the two are tightly plugged at this time.

[0031] Among them, the two ends of the connection part 210 are respectively rotatably provided with a snap-fitting part 230, and the electrical device socket 100 is provided with a snap-fitting block 110 that is mutually snapped with the snap-fitting part 230. When the plug-in part 220 and the electrical device socket 100 are plugged into place, the snap-fitting part 230 and the snap-fitting block 110 are mutually snapped to prevent the plug 200 from loosening. Specifically, the snap-fitting part 230 is arranged at the top and bottom of the connection part 210, and the two snap-fitting parts 230 are arranged facing each other, which can clamp the snap-fitting block 110 of the electrical device socket 100 from both sides. After the snap-fitting part 230 and the snap-fitting block 110 are connected, the plug 200 can be prevented from being separated and loosened from the electrical device socket 100, effectively avoiding the situation where the power supply of the electrical device is cut off due to accidental pulling of the cable 300.

[0032] An indicator platform 231 is provided at the end of the buckling portion 230, and the indicator platform 231 is provided with two colors, corresponding to the buckled state and the unbuckled state of the buckling portion 230 respectively. When the plug-in portion 220 is plugged into the electrical device socket 100, the end of the buckling portion 230 is lifted by the buckling block 110. At this time, the color displayed by the indicator platform 231 of the buckling portion 230 indicates that the plug-in portion 220 and the electrical device socket 100 are not fully plugged in. When the plug-in portion 220 and the electrical device socket 100 are fully plugged in, the buckling portion 230 and the buckling block 110 are fully buckled. At this time, the color displayed by the indicator platform 231 indicates that the plug-in portion 220 and the electrical device socket 100 are fully plugged in. The user can intuitively understand the connection status of the plug 200 and the electrical device socket 100 according to the color status of the indicator platform 231. Effectively prevent poor contact and current overload caused by incomplete plugging.

[0033] In some embodiments of the present invention, Figure 1-Figure 3As shown, the indicator platform 231 is disposed on the side of the buckle part 230 close to the cable 300, and the indicator platform 231 is provided with two inclined surfaces. When the buckle part 230 rotates, the user can observe the color on the inclined surface to identify the connection status of the plug part 220.

[0034] Specifically, the inclined surface displayed by the indicator 231 on the side facing the user's line of sight is different according to the rotation angle of the buckle part 230. When the buckle part 230 is in a rotating state, the inclined surface displayed by the indicator 231 indicates that the plug-in part 220 is not fully plugged into the electrical device socket 100. When the buckle part 230 is stationary, that is, the buckle part 230 is fully buckled with the buckle block 110, the inclined surface displayed by the indicator 231 indicates that the plug-in part 220 is fully plugged into the electrical device socket 100.

[0035] In a further embodiment, Figure 1 and Figure 2 As shown, the inclined surface is divided into a first inclined surface 231a and a second inclined surface 231b. The first inclined surface 231a is parallel to the top plane of the plug-in portion 220. One end of the second inclined surface 231b is connected to the first inclined surface 231a, and the other end extends obliquely toward the buckling portion 230. The first inclined surface 231a and the second inclined surface 231b are at an obtuse angle. Specifically, the first inclined surface 231a faces the user's field of vision when the buckling portion 230 is stationary or buckled with the buckling block 110. When the buckling portion 230 rotates, the second inclined surface 231b is continuously displayed within the user's field of vision. When the buckling portion 230 is buckled with the buckling block 110, the first inclined surface 231a is displayed within the user's field of vision, and only a small area of ​​the second inclined surface 231b is displayed within the field of vision or the second inclined surface 231b is not displayed within the user's field of vision.

[0036] Furthermore, the surface of the first inclined surface 231a is provided with a green coating, the surface of the second inclined surface 231b is provided with a red coating, and the length of the first inclined surface 231a is greater than the length of the second inclined surface 231b. Specifically, the green coating of the first inclined surface 231a indicates that the plug 200 and the electrical device socket 100 are plugged in place, and the red coating of the second inclined surface 231b indicates that the plug 200 and the electrical device socket 100 are not fully plugged in, and the user needs to check whether the plug portion 220 is fully plugged in.

[0037] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the connecting portion 210 is provided with an articulated seat 211, the middle portion of the buckle portion 230 is hinged to the articulated seat 211, and a return torsion spring is provided between the buckle portion 230 and the articulated seat 211. Specifically, the return torsion spring is a technical solution well known to those skilled in the art, and will not be described in detail in this embodiment. The articulated seat 211 can form a certain height between the buckle portion 230 and the connecting portion 210, expand the rotation stroke of the buckle portion 230, and improve the pressing feel.

[0038] In a further embodiment, Figure 1 and Figure 2 As shown, the side where the buckle block 110 and the buckle part 230 abut against each other is wedge-shaped. Specifically, the side where the buckle block 110 and the buckle part 230 contact each other is wedge-shaped, which enables the two to move in the vertical direction and optimizes the rotation damping of the buckle part 230.

[0039] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a metal spring part 120 is provided on one side of the snap-fit ​​block 110. When the snap-fit ​​part 230 is snapped with the snap-fit ​​block 110, the snap-fit ​​part 230 hits the metal spring part 120 to make a sound, and at this time, the plug 200 and the electrical device are plugged in place. Specifically, when the snap-fit ​​part 230 and the snap-fit ​​block 110 are snapped into place, the end of the snap-fit ​​part 230 hits the metal spring part 120, and the metal spring part 120 makes a clicking sound. The user confirms that the plug 200 is fully plugged into the electrical device socket 100 through the positive feedback sound of the metal spring part 120.

[0040] In a further embodiment, Figure 1 As shown, the metal spring piece portion 120 adopts a pot piece structure. Specifically, the pot piece structure is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0041] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the circumference of the connecting portion 210 gradually narrows toward the cable 300, so that the user can hold the connecting portion 210 and the cable 300 conveniently.
