Elastic collision type sealed electric plug
ActiveCN107230858AReliable contactThere will be no gapsCoupling contact membersCouplings bases/casesElastic collisionContactor
The invention discloses an elastic collision type sealed electric plug, and aims to solve the problem that the existing air plug is powered on by means of pin connection, a female head is contacted with a male head by a tubular piece which is separated into two valves, thus the elasticity is relatively week, when the plug is plugged for many times, poor contact is caused, and the poor contact is random. The invention designs a novel elastic collision type sealed electric plug which is supported by a spring and the end face is contacted and conducted (especially a round end face is contacted and conducted). The electric plug is composed of a fixed plug and a movable plug; and contact devices of the fixed plug and the movable plug carry out reliable surface contact under the counterforce of a compression spring to complete a conductive function. In the elastic collision type sealed electric plug provided by the invention, the movable plug adopts the compression spring to support a touch head; when the fixed plug and the movable plug are connected and tightened, a part of the touch head beyond the contact end face of a moveable guide sleeve is inserted to a round hole of a fixed plug pin, and a cylindrical end face of the touch head is contacted with the bottom surface of the round hole of the fixed plug pin.
