[0033] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are 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.
[0034] The embodiment of the present application provides a public charging socket for an electric vehicle charging pile, thereby solving the problem that when the plug is plugged into the socket, the plug is easily loosened from the socket, thereby improving the service life of the public charging plug.
[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0036] Example:
[0037] like Figure 1-Figure 3 As shown, a public charging socket for an electric vehicle charging pile includes a socket core 20 and a socket cover 30, wherein the socket core 20 is used for connecting a plug;
[0038] The socket cover 30 is rotatably connected to the socket core 20 via a connecting shaft 301;
[0039] The socket cover 30 is provided with a limiting member 31, and the limiting member 31 includes a limiting frame 311 and a cover plate 312, and the cover plate 312 is installed on the limiting frame 311, and the cover plate 312 and the limiting frame 311 form a limiting groove;
[0040] The stopper 31 is engaged with the socket cover 30 via the engaging groove 313;
[0041] The limiting groove is adapted to the plug;
[0042] When the socket cover 30 and the socket core 20 are closed, the limiting member 31 is clamped on the plug through the limiting groove and contacts the socket core 20 , so that the limiting member 31 limits the plug.
[0043] By setting a limit member 31, the limit member 31 is set in the form of a limit frame 311 and a cover plate 312, and the limit groove formed by the limit frame 311 and the cover plate 312 is used to limit the plug, so as to solve the problem in the prior art that the socket on the public charging socket needs to be repeatedly plugged in and out of the plug, resulting in the socket on the socket core 20 becoming larger after repeated use, and when the plug is plugged into the socket core 20, the plug and the socket are prone to looseness, resulting in poor contact between the plug and the socket. The socket cover 30 can effectively realize the function of rain protection.
[0044] At the same time, a snap-in groove 313 is provided. The snap-in groove 313 can ensure the stability of the limit member 31 when sliding. The snap-in groove 313 can also facilitate the control of the limit member 31 by hand and adjust the position between the limit member 31 and the socket cover 30. When the socket hole on the socket core 20 has not yet become larger, the limit member 31 is away from the socket core 20 and snap-fitted with the socket cover 30, and the limit member 31 will not be separated from the socket cover 30. Only when the socket hole on the socket core 20 is repeatedly plugged in and the socket hole becomes larger, it is necessary to manually snap the limit member 31 onto the plug to realize the limiting of the plug by the limit member 31.
[0045] like Figure 1-Figure 5 As shown, a torsion spring 302 is sleeved on the outer surface of the connecting shaft 301, and the socket cover 30 is rotatably connected to the socket core 20 through the torsion spring 302;
[0046] In the initial state, the socket cover 30 and the socket core 20 are in a closed state under the action of the torsion spring 302 .
[0047] By providing the torsion spring 302 and utilizing the rotational force of the torsion spring 302 to automatically reset, the tightness of the socket cover 30 and the socket core 20 can be achieved, and the limiting effect of the limiting member 31 on the plug can be further enhanced. At the same time, it can effectively solve the problem that after charging is completed, the socket cover 30 and the socket core 20 are often forgotten to be closed, and rainwater and dew enter the jack on the socket core 20, causing damage to the socket core 20.
[0048] like Figure 1-Figure 6 As shown, the depth of the limiting groove is the same as the depth of the plug exposed on the outer surface of the socket core 20. When the limiting member 31 is clamped to the plug, the limiting groove in the limiting member 31 is completely sleeved on the plug.
[0049] By setting the depth of the limiting groove, the plug can be effectively prevented from moving along the depth direction of the limiting groove, and the limiting effect of the limiting member 31 on the plug can be further improved.
[0050] The socket core 20 is provided with a first wire groove 21 , and the socket cover 30 is provided with a second wire groove 32 corresponding to the first wire groove 21 at one end close to the socket core 20 .
[0051] When in use, the connecting wire of the plug is located in the first wire groove 21 and the second wire groove 32 , and the first wire groove 21 and the second wire groove 32 are used to limit the position of the connecting wire of the plug.
[0052] The first wire groove 21 is integrally formed with the socket core 20 , and a socket base 10 is provided at one end of the socket core 20 away from the socket cover 30 , and the socket base 10 is used to install the socket core 20 on the charging pile.
[0053] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0054] 1. By setting a limit member 31, the limit member 31 is set in the form of a limit frame 311 and a cover plate 312, and the limit groove formed by the limit frame 311 and the cover plate 312 is used to limit the plug, which solves the problem in the prior art that the socket on the public charging socket needs to be repeatedly plugged in and out of the plug, resulting in the socket on the socket core 20 becoming larger after repeated use. When the plug is plugged into the socket core 20, the plug and the socket are prone to looseness, resulting in poor contact between the plug and the socket. The socket cover 30 can effectively realize the function of keeping out rain.
[0055] 2. At the same time, a snap-in groove 313 is provided. The snap-in groove 313 can ensure the stability of the limit member 31 when sliding. The provision of the snap-in groove 313 can also facilitate the control of the limit member 31 by hand and adjust the position between the limit member 31 and the socket cover 30. When the socket hole on the socket core 20 has not yet become larger, the limit member 31 is away from the socket core 20 and snap-fitted with the socket cover 30, and the limit member 31 will not be separated from the socket cover 30. Only when the socket hole on the socket core 20 is repeatedly plugged in and the socket hole becomes larger, it is necessary to manually snap the limit member 31 onto the plug to realize the limit of the plug by the limit member 31.
[0056] 3. By setting the torsion spring 302, the rotational force of the torsion spring 302 is utilized to automatically reset, so as to achieve the tightness of the socket cover 30 and the socket core 20, further improving the limiting effect of the limit member 31 on the plug. At the same time, it can effectively solve the problem that after charging is completed, the socket cover 30 and the socket core 20 are often forgotten to be closed, and rain and dew enter the jack on the socket core 20, causing damage to the socket core 20.
