Problems solved by technology
The pin terminal is in direct contact with the water vapor in the air. The complex acidic or alkaline impurities in the water vapor will corrode the surface of the pin terminal, making the surface layer of the terminal less conductive, and the contact resistance will increase during charging, resulting in serious heating and shortening the battery life. The service life of the charging gun
Excessive accumulation of water vapor will shorten the creepage distance and cause safety problems

Embodiment Construction
[0038] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0039] A charging gun capable of protecting pin terminals in this embodiment, such as Figure 1 to Figure 6 As shown, it includes a gun body 1, a cable 2, a charging head 3 and a pin terminal 4, the cable 2 is passed through the gun body 1 and is electrically connected to the pin terminal 4, and the charging head 3 is installed at the front end of the gun body 1 , the pin terminal 4 is arranged in the charging head 3 , and the charging head 3 is provided with an accommodating space 6 , and the accommodating space 6 is provided with a flexible capsule 8 . The charging gun also includes an injection and suction mechanism 9 for filling the flexible capsule 8 with fluid, or sucking back the fluid in the flexible capsule 8, when the injection and suction mechanism 9 fills the flexible capsule 8 with the fluid , the flexible capsule 8 expands and exte...

The invention provides a charging gun with a pin terminal capable of being protected. The charging gun comprises a gun body, a charging head and the pin terminal. The charging head is mounted at the front end of the gun body, and the pin terminal is arranged in the charging head. A containing space is formed in the charging head and provided with a flexible bag. The charging gun further comprisesan injection and suction mechanism used for fluid injection and suction. Compared with the prior art, when the charging gun is in a non-use state, the injection and suction mechanism enables the flexible bag to be filled with a fluid, the flexible bag expands and extends, thus the outer side of the pin terminal is wrapped with the flexible bag, and / or a front end opening of the charging head is blocked; and thus the situation that dust and water vapor adhere to the outer surface of the pin terminal can be avoided, corrosion is avoided, and the service life of the pin terminal is prolonged. When the charging gun needs to be used for charging a car, the fluid in the flexible bag is sucked back through the injection and suction mechanism, the flexible bag is contracted and reset into the containing space, and normal use of the charging gun is not influenced by the flexible bag.
Description
technical field [0001] The invention relates to the technical field of charging piles, in particular to a charging gun capable of protecting pin terminals. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Because electric vehicles have less impact on the environment than traditional vehicles, their prospects are widely optimistic. In recent years, the penetration rate of electric vehicles has become higher and higher, and the problem of how to charge electric vehicles in a timely and effective manner has also followed. Charging piles, as a kind of equipment specially designed to facilitate the timely charging of electric vehicles and other products, have received widespread attention and recognition once they came out. [0003] The charging gun is an indispensable device for electric vehicle chargin...
