[0027] Please refer to Figures 1 to 4 , Figure 1 It is a schematic diagram of the electrical plugging structure of the present application, Figure 2 It is Figure 1 The sectional view taken along line A-A' of Figure 3 It is an exploded perspective view of the first embodiment of the electrical plugging structure and Figure 4A cross-sectional perspective view of a first embodiment of an electrical plug-in structure. As shown in the figure, the present application provides an electrical plug-in structure 1, which includes a socket 11 and a plug 12. The socket 11 has a socket body 111 and two pins 112. The socket body 111 has a slot 113 and a limiting convex portion 114. The two pins 112 are disposed in the slot 113. The limiting convex portion 114 is located between the two pins 112, and the limiting convex portion 114 separates the two pins 112. The plug 12 has a plug body 121. The plug body 121 has a limiting concave portion 122 and two jacks 123. The plug body 121 is fitted into the slot 113. The outer contour of the plug body 121 corresponds to the inner contour of the slot 113 of the socket 11. The limiting convex portion 114 is correspondingly fitted into the limiting concave portion 122, and the two pins 112 pass through the two jacks 123. The designs of the socket 11 and the plug 12 of the electrical plug-in structure 1 of the present application are both non-standard structural designs of the socket 11 and the plug 12.
[0028] Please refer back to Figure 3 and Figure 4 In this embodiment, the inner wall of the slot 113 of the socket 11 has a first slot wall 1131, a second slot wall 1132, a third slot wall 1133, and a fourth slot wall 1134. The limiting convex portion 114 extends from the first slot wall 1131 towards the second slot wall 1132, that is, the limiting convex portion 114 extends from the inner wall of the first slot wall 1131 of the slot 113 through the space between the two pins 112, and the two pins 112 are symmetrically located on both sides of the limiting convex portion 114. The third slot wall 1133 and the fourth slot wall 1134 are connected to both sides of the first slot wall 1131 and the second slot wall 1132. Further, the second slot wall 1132 is a plane adjacent to the two pins 112, the third slot wall 1133 is an arc surface adjacent to the outside of the pin 112, and the fourth slot wall 1134 is an arc surface adjacent to the outside of the other pin 112.
[0029] As described above, the contour of the plug body 121 of the plug 12 corresponds to the inner contour of the slot 113 of the socket 11. The end face of the plug body 121 has two jacks 123, and the two jacks 123 are symmetrically located on both sides of the limiting concave portion 122. The side surface of the plug body 121 has a limiting concave portion 122. The limiting concave portion 122 is recessed inward from the side surface of the plug body 121 through the space between the two jacks 123 to form a groove, that is, the groove depth of the limiting concave portion 122 exceeds the space between the two jacks 123, and the groove of the limiting concave portion 122 extends towards the end face of the plug body 121 to form a notch. In other words, the two jacks 123 and the notch of the limiting concave portion 122 are located on the same end face. In addition, the side contour shape of the plug body 121 corresponds to the first slot wall 1131, the second slot wall 1132, the third slot wall 1133, and the fourth slot wall 1134 of the slot 113.
[0030] In this embodiment, the plug 12 is inserted into the slot 113 of the socket 11. The limiting recess 122 of the plug body 121 is aligned with the limiting protrusion 114 in the slot 113, enabling the limiting protrusion 114 to enter the groove of the limiting recess 122 through the notch on the end face of the plug body 121. In other words, the position of the plug body 121 is restricted by the structures of the limiting recess 122 and the limiting protrusion 114, and the structural positions of the limiting recess 122 and the limiting protrusion 114 also limit the forward and reverse directions of the plug body 121 inserted into the slot 113, effectively preventing the user from inserting it in the wrong direction. As described above, according to the user's needs, the limiting protrusion 114 can be adjusted to extend from the second groove wall 1132 towards the first groove wall 1131, thereby changing the forward and reverse directions of the plug body 121 inserted into the slot 113. Furthermore, the two pins 112 in the slot 113 also insert into the two jacks 123 of the plug body 121. The outer contour of the plug body 121 conforms to the inner contour of the slot 113 of the socket 11, enabling the plug body 121 of the plug 12 and the slot 113 of the socket 11 to be completely fitted together, thus ensuring a firm connection between the socket 11 and the plug 12.
[0031] Please refer to Figure 5 and Figure 6 , Figure 5 is an exploded perspective view of the second embodiment of the electrical plug-in structure and Figure 4 is a sectional perspective view of the second embodiment of the electrical plug-in structure. As shown in the figure, the difference between this embodiment and the first embodiment lies in the structures of the limiting protrusion 114 and the limiting recess 122. In this embodiment, the limiting protrusion 114 extends from the bottom of the slot 113 towards the slot opening, and the limiting protrusion 114 of the slot 113 is located between the two pins 112. The limiting recess 122 of the plug body 121 corresponds to the limiting protrusion 114 of the slot 113, so that the limiting recess 122 is located between the two jacks 123. The inner part of the slot 113 has a first groove wall 1131, a second groove wall 1132, a third groove wall 1133 and a fourth groove wall 1134. The first groove wall 1131 and the second groove wall 1132 are arranged along the arrangement direction of the two pins 112, and the first groove wall 1131 and the second groove wall 1132 are planes adjacent to the two pins 112. The third groove wall 1133 and the fourth groove wall 1134 are connected to both sides of the first groove wall 1131 and the second groove wall 1132. The third groove wall 1133 is an arc surface adjacent to the outside of the pin 112, and the fourth groove wall 1134 is an arc surface adjacent to the outside of the other pin 112.
[0032] As described above, in the present embodiment, the limiting recess 122 is a hole groove, the limiting protrusion 114 is a column, and the hole groove shape of the limiting recess 122 corresponds to the column shape of the limiting protrusion 114. If the hole groove of the limiting recess 122 is a linear hole, a cross hole, a round hole, a triangular hole or a T-shaped hole, the column of the limiting protrusion 114 correspondingly is a linear column, a cross column, a round column, a triangular column or a T-shaped column. The present embodiment does not limit the shapes of the limiting recess 122 and the limiting protrusion 114, and the above shapes can be adjusted according to the needs of the user.
[0033] In the present embodiment, when the plug 12 is inserted into the slot 113 of the socket 11, the limiting recess 122 of the plug body 121 is aligned with the limiting protrusion 114 in the slot 113. The limiting protrusion 114 of the present embodiment is located in the exact middle of the slot 113, and the limiting recess 122 corresponding to the limiting protrusion 114 is also located in the exact middle. If the limiting protrusion 114 of the present embodiment is a non-directional structural column, such as a linear column, a cross column or a round column, etc., then the combination of the limiting protrusion 114 and the limiting recess 122 has no positive or negative direction restrictions. In other words, the above plug body 121 can be inserted into the slot 113 in either the positive or negative direction. If the limiting protrusion 114 of the present embodiment is a directional structural column, such as a triangular column (for example, with the corner end facing up and the straight edge facing down as a restriction) or a T-shaped column, etc., then the combination of the limiting protrusion 114 and the limiting recess 122 has positive and negative direction restrictions. In other words, the above plug body 121 needs to be inserted into the slot 113 in the correct direction.
[0034] In summary, the present application provides an electrical plugging structure including: a socket and a plug. The socket has a limiting protrusion, and the plug has a limiting recess. The above combination of the limiting protrusion and the limiting recess is used as the plugging combination restriction between a standardized plug and a non-standardized socket, or the combination restriction between a non-standardized plug and a standardized socket. At the same time, the limiting protrusion and the limiting recess can be used to limit the plugging direction between a non-standardized plug and a non-standardized socket. The designs of the plug and the socket of the electrical plugging structure of the present application are both non-standardized structural designs, that is, they can only be used for plugging specific sockets and plugs, and have a structural mechanism to prevent incorrect plugging of standardized plugs or sockets.
