Description

Technical Field

[0001] The utility model relates to the technical field of quick connection plugs, in particular to a power quick connection plug. Background Art

[0002] The connector of general electronic products and the plug of electrical appliances are called plugs. Household AC power plugs and sockets have a male connector with a rod or copper plate protrusion, which is physically inserted into a female connector-type power socket with a slot or a hole. The plug and cable of the charging pile of new energy vehicles are fixedly connected, which is inconvenient to replace if damaged. The power quick-connect plug technology is used in many fields, but it has not yet been implemented on charging piles.

[0003] The existing power quick-connect plug cannot be directly used on the charging pile. Since the cable of the charging pile is thicker and heavier, the connection of the existing quick-connect plug cannot bear the weight of the charging pile cable, and there is a risk of falling off, affecting the charging stability. Disconnection leakage may cause personal injury; the existing charging pile plug and the car connection lack an anti-falling function. The charging pile is relatively dense and there are people coming and going, and there is a risk of being knocked off, resulting in charging being unable to be completed normally, which is time-consuming and laborious. Therefore, a power quick-connect plug is proposed to address the above problems. Utility Model Content
