[0019] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figure 1 As shown, a conductor-hidden electric vehicle plug comprises a shell 1 and a conductor 2 arranged inside the shell. The shell is a cavity structure with one end open. A protective baffle 3 matching the shell is also provided in the cavity of the shell. A spring 4 is connected to the protective baffle, which is connected to the side of the shell away from its open end. A guide hole 301 is provided on the protective baffle to be slidably connected to the conductor. When the spring is in a naturally extended state, the protective baffle shields the conductor and hides the conductor behind the protective baffle, which can avoid the risk of electric shock caused by accidentally touching the conductor due to improper charging operation. When the plug is inserted into the socket for charging, the protective baffle moves along the conductor toward the inside of the plug under the push of the fixed seat inside the socket, and the conductor of the plug extends out from the guide hole on the protective baffle and embeds into the conductive hole on the fixed seat inside the socket, thereby realizing power supply between the plug and the socket.

[0021] The shell includes a front shell 101 and a rear seat body, one end of the front shell is connected to the rear seat body, the front shell is a stepped structure, including a first shell 10101 and a second shell 10102, the second shell is located between the first shell and the rear seat body, and its outer diameter is larger than the outer diameter of the first shell, when the plug is inserted into the socket, the first shell is embedded in the socket, and the second shell is in conflict with the outer end surface of the socket, so as to achieve a fast and stable connection between the plug and the socket, the rear seat body includes a rear shell 102 and a fixing block 103 arranged in the rear shell, the conductor and the spring are both connected to the fixing block, so as to improve the structural stability of the conductor and the spring, the conductor and the rear shell are connected by screw assembly, so as to facilitate disassembly and assembly, and a threading hole 10201 is provided at one end of the rear shell away from the front shell, so as to facilitate the wire to extend into the shell and connect with the conductor. There are four conductors, which are divided into two groups. Each group of conductors includes a positive conductor 201 and a negative conductor 202. The arrangement direction of the positive conductor and the negative conductor in each group is opposite to that of the other group. The advantage of this structural design is that there is no need to deliberately distinguish the upper and lower sides or the front and back sides of the plug when charging. It can be directly inserted into the socket, which is more convenient to use.

[0022] Working principle of this utility model:

[0023] Use Figure 2 The electric vehicle charger shown in the figure adopts the plug of the utility model. When charging the electric vehicle, the front shell 101 of the plug is inserted into the socket, and the fixing seat inside the socket pushes the protective baffle 3 to move toward the side of the rear shell 1012 of the plug until the protective baffle 3 conflicts with the fixing block 103. At this time, the conductor 2 passes through the guide hole 301 of the protective baffle 3 and is embedded in the conductive hole in the socket, and then Figure 2 The other end of the electric vehicle charger is connected to the mains electricity to realize the power supply between the electric vehicle plug and the electric vehicle socket, thereby realizing the charging function of the electric vehicle.

[0024] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
