Aerial plug

Abstract

The invention relates to a solderless aerial plug used for machine riveting, which aims at overcoming the defects of poor soldering and unsoldering easily because of the fixed soldering manner between a metal contact pin used in the plug and a lead wire in the prior art. The aerial plug comprises an insulating body and a metal contact pin arranged inside the body; one end part of the body is provided with an annular groove; the outer wall of the annular groove is provided with a notch; the outer wall of the annular groove is connected with a nut; the end part of the metal contact pin is in a fork structure; the horn of fork corresponds to the annular groove; and the horn of fork is respectively fixed on the inner side of the outer wall of the annular groove and the outer side of the inner wall of the annular groove. The annular groove with an opening is arranged at the end part of the body; the metal contact pin is fixed in the annular groove; the outer wall of the annular groove is fixed through a tightened nut; the outer wall of the annular groove is extruded and deformed inwards; the distance between the two forks of the metal contact pin becomes smaller so as to tighten the lead wire and completely realize mechanical tightening; and therefore, the step of soldering is eliminated, the working procedure is simpler, the operation is simple, the labor intensity of workers is decreased, and the requirement for workers is also decreased.

Description

technical field [0001] The invention relates to a structure of a plug, in particular to a mechanical fastening and welding-free aviation plug. Background technique [0002] The aviation plug is a kind of quick plug used in aviation. They are all metal shells. The plug and socket have turnbuckles. After connection, they can be tightened and fixed without falling off. [0003] In the existing aviation plugs, the lead wires and the metal pins are generally welded, which is easy to cause false welding or desoldering of the welding position. The production efficiency is high and the yield of the product is low. If there is vibration, it is easy to cause connection failure The part is loose, which causes the lead wire to be separated from the metal pin, resulting in an open circuit. The welding method requires special personnel to operate, the process is cumbersome, the requirements for workers are relatively high, and the labor intensity is relatively high. [0004] The Chinese...

Problems solved by technology

[0005] The invention solves the disadvantages of soldering between the metal pin and the lead wire in the plug used in the prior art, which may easily cause virtual welding and desoldering, and provides a mechanically fixed method for connecting the lead wire and the metal plug. Pin, connect reliable aviation plug

[0006] The present invention also solves the disadvantages of many procedures, inconvenient operation and high labor intensity in the prior art that professional workers are required to carry out welding, and provides an aviation plug that uses mechanical fastening, low labor intensity, simple operation and simple process
