Description

Technical Field

[0001] The utility model relates to the technical field of new energy charging piles, and more specifically, to a new energy charging pile conductive connection structure. Background Art

[0002] A charging pile is a device for charging new energy vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding operations such as charging method, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] After searching, the utility model patent with Chinese application number CN201620527235.0 discloses a charging pile that is easy to replace the charging gun, including a main body and a charging gun, and also including a first wire, a second wire, a conductive contact plug and an intermediate conductive seat. One end of the first wire is connected to the main body, and the other end is provided with a conductive contact plug. One end of the second wire is connected to the charging gun, and the other end is also provided with a conductive contact plug. The first wire and the second wire are respectively plugged into the two ends of the intermediate conductive seat through the conductive contact plug, and the first wire and the second wire are electrically connected through the intermediate conductive seat. By setting a combination of the first wire, the second wire, the conductive contact plug and the intermediate conductive seat, during long-term use, if a component in the charging gun or the intermediate conductive seat is damaged, the corresponding component can be directly replaced, without saving a lot of resources and costs. It can continue to be used by directly replacing it, and will not cause the charging system to be paralyzed.

[0004] It electrically connects the first wire and the second wire by inserting the conductive contact connector into the interior of the middle conductive seat. When people charge new energy vehicles, they cannot avoid pulling the charging gun. During the pulling process, the conductive contact plug will be pulled out from the interior of the middle conductive seat, causing the charging gun to fall off. The stability of the connection of its conductive connection structure is poor. Since the middle conductive seat and the conductive contact plug are exposed to the outside, when people move the charging gun, the middle conductive seat and the conductive contact plug will come into contact and collide with the ground or other objects, which may easily cause damage to the middle conductive seat and the conductive contact plug. At the same time, the middle conductive seat and the conductive contact plug rub against the ground and other objects, which may easily cause wear of the middle conductive seat and the conductive contact plug, thereby reducing their service life.
