Description

Technical Field

[0001] The utility model relates to the technical field of charging gun terminals, and more specifically, to a charging gun terminal with a guiding function. Background Art

[0002] New energy electric vehicles are a green means of transportation with broad development prospects. When charging new energy vehicles, the charging gun is usually plugged into the charging seat of the car to supplement the power supply. The charging gun usually includes a household power plug connected to a fixed socket, a charging gun head, and an online control and protection device. The charging gun terminal is an important component of the charging gun head.

[0003] At present, the charging gun terminals on the market play a vital role in the new energy vehicle charging system. Their structure and functions include power transmission, safety protection, control guidance, etc. The charging gun usually has multiple terminals for transmitting power. When the charging gun is inserted into the charging gun holder, the terminals need to be aligned.

[0004] However, it is difficult to plug the charging gun terminals together, which will lead to a decrease in charging efficiency. Forcibly plugging the charging gun and the charging gun holder may cause the terminals to be inserted crooked and damaged. At the same time, excessive force when inserting the charging gun may damage the female terminal of the charging gun holder. Misoperation during charging may cause the charging gun and the terminal to be pulled out, causing personal injury. Therefore, a charging gun terminal with a guiding function is proposed to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a charging gun terminal with a guiding function which facilitates the insertion of the charging gun terminal into the female terminal of the charging gun seat, prevents damage to the female terminal of the charging gun, and prevents the terminal from falling off the charging gun.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A charging gun terminal with a guiding function comprises a guiding part, a power supply column is arranged on one side of the guiding part, and a fixing part is arranged on the end of the power supply column away from the guiding part; wherein, the power supply column is arranged in a cylindrical structure; the guiding part comprises a second guide head arranged near the power supply column, a first guide head is arranged on the end of the second guide head away from the power supply column, and a first groove is arranged coaxially around the first guide head.

[0008] The utility model is further configured as follows: the first guide head is configured as a cylindrical structure with one end converged toward the top, and its diameter is smaller than the diameter of the energy supply column; the second guide head is configured as a conical structure with a platform at one end; the first guide head and the second guide head are coaxially arranged.

[0009] By adopting the above technical solution, the first guide head is used to roughly guide the charging gun terminal to facilitate alignment with the charging gun seat, and the second guide head is used to finely guide the charging gun terminal so that the charging gun terminal can be smoothly inserted into the female terminal of the charging gun seat. After being tightly inserted, it is locked with the buckle inside the charging gun seat through the first groove, so that the charging gun terminal will not fall off after being tightly inserted.

[0010] The utility model is further configured as follows: the fixing portion includes a second groove, the second groove is arranged around the end of the energy supply column away from the guide portion, the second groove is coaxially arranged with the energy supply column, the end of the second groove away from the energy supply column is provided with a first limit platform, the first limit platform is arranged at the end of the energy supply column away from the guide portion, the first limit platform is arranged as a cylindrical structure, and its diameter is greater than the diameter of the energy supply column.

[0012] By adopting the above technical solution, when the charging gun is inserted into the charging gun seat until the plane of the first limit platform close to the energy supply column is close to the plane of the female terminal of the charging gun seat, the charging gun is prevented from being forcefully inserted into the male terminal of the charging gun seat beyond the length of the female terminal, causing damage to the female terminal and causing economic losses. At the same time, the buckle on the female terminal of the charging gun seat that is adapted to the shape of the second groove clamps the charging gun terminal to prevent the terminal from falling off or shifting, causing charging failure.

[0013] The utility model is further configured as follows: the second limit platform is provided with a fixed base away from the first limit platform, the fixed base is configured as a cylindrical structure, and its diameter is larger than the diameter of the second limit platform, the fixed base is coaxially arranged with the second limit platform, and a third groove is coaxially opened on the fixed base.

[0014] By adopting the above technical solution, the plane of the second limit platform is close to the charging front seat shell, further preventing the female terminal from being damaged when the charging gun is inserted into the charging gun seat. The third groove opened on the fixed base fixes the entire charging gun terminal on the charging gun, preventing the charging gun terminal from being separated from the charging gun, resulting in failure to smoothly insert the charging gun seat, causing charging failure and affecting user experience.

Use the second guide head to precisely guide the charging gun terminal so that the charging gun terminal can be smoothly inserted into the female terminal of the charging gun holder. After being inserted tightly, the first groove and the buckle inside the charging gun holder are locked so that the charging gun terminal will not fall off after being inserted tightly.

[0019] 2. When the charging gun is inserted into the charging gun holder, until the plane of the first limit platform close to the energy supply column is close to the plane of the female terminal of the charging gun holder, prevent the charging gun from being inserted into the male terminal of the charging gun holder with force beyond the length of the female terminal, causing damage to the female terminal and causing economic losses. At the same time, the buckle on the female terminal of the charging gun holder that is adapted to the shape of the second groove clamps the charging gun terminal to prevent the terminal from falling off or shifting, causing charging failure.

[0020] 3. The plane of the second limit platform is close to the outer shell of the front charging seat to further prevent the female terminal from being damaged when the charging gun is inserted into the charging gun seat. The third groove opened on the fixed base fixes the entire charging gun terminal on the charging gun to prevent the charging gun terminal from being detached from the charging gun, resulting in failure to insert the charging gun seat smoothly, causing charging failure and affecting user experience. The wiring slot opened on the fixed base connects the wires to provide power to the entire charging gun terminal, and then provides power to the charging gun seat to realize the charging function.
