Elastic collision type sealed electric plug

Abstract

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.

Description

technical field [0001] The invention relates to the field of electrical components, in particular to the field of electric plugs, in particular to a snap-on type sealed electric plug. Background technique [0002] The two ends of the existing aviation plug are divided into a male head and a female head, and the male head and the female head are usually electrically connected by pin connection. Among them, the male head is a needle-shaped cylindrical structure, and the female head is a two-slotted tubular structure. Because the two grooves of the female head naturally divide the tubular structure into two pieces, after kneading them together, they have a certain degree of elasticity; in practical applications, the male head is inserted into the tubular structure of the female head, through the inner wall of the tubular structure and the Male cylindrical contact for conductive connection. The aviation plug with this structure has low manufacturing cost, is relatively common ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the invention of the present invention is: for the existing aviation head plug adopts pin connection mode to conduct electricity, and the female head is in contact with the male head by a tubular piece separated into two lobes, the elasticity is weak, and when plugging and unplugging for many times, the female head will be damaged. The separation of the two tubular pieces is too large, which leads to the failure of normal contact between the inner wall of the male head and the female head, resulting in poor contact, and this poor contact is random, which seriously affects the research and development and / or debugging of electrical equipment.
