Dustproof anti-drop plug connector

Abstract

The invention discloses a dustproof anti-drop plug connector. The dustproof anti-drop plug connector includes a housing with a socket slot in a horizontal direction and a plug for plugging into the socket slot, wherein a first mounting cavity is arranged in the housing; a first screw is rotatably connected to the inside of the first mounting cavity, and a motor for driving the first screw to rotate is rotatably connected to the inside of the first mounting cavity; a guiding slide sleeve is in threaded connection with the first screw; a guiding slide slot is formed in the guiding slide sleeve;a guiding slide rod is slidably connected in the guiding slide slot; the lower end of the guiding slide rod is hinged to the upper end of a connecting rod through a slide pin; the middle position of the connecting rod is hinged to the side wall of the first mounting cavity; the lower end of the connecting rod extends into the socket slot and is equipped with a baffle plate for controlling opening / closing of the socket slot; and a selection switch and a control button for controlling the action of the motor and a clamping device are arranged at the right side of the housing. The dustproof anti-drop plug connector is simple in structure, can effectively prevent the dust entering the housing, and can prevent the plug from dropping at the same time.

Description

technical field [0001] The invention relates to the technical field of plug connectors, in particular to a dust-proof and fall-off-proof plug connector. Background technique [0002] In recent years, more than 30 serious fire and explosion accidents caused by static electricity have occurred in petrochemical enterprises in my country. Many industrially developed countries have established electrostatic research institutions. my country has carried out some electrostatic research work since the end of the 1960s. Since the 1980s, my country's electrostatic research has developed extremely rapidly. In 1981, the Chinese Physical Society Electrostatic Professional Committee was established. From the perspective of general physical phenomena, when two objects rub against each other, the free electrons on the surface can continuously communicate with each other through the object interface. For a good conductor of electricity, when the two objects are separated, the excess electro...

[0003] In dry and windy autumn, people often encounter this phenomenon in daily life: when undressing to sleep at night, crackling sounds are often heard in the dark, accompanied by blue light; The other party will suddenly feel tingling pain like fingertips, which is shocking; when you get up to comb your hair in the morning, the hair will often "float", and the more you straighten it, the more messy it will be; The sound of "pop, pop, pop" is the static electricity that occurs in the human body. Electrostatic discharge may cause malfunction or malfunction of electronic equipment, causing electromagnetic interference; high-voltage electrostatic discharge may cause electric shock, endangering personal safety; Products or dust, oil mist production site is very easy to cause explosion and fire

A two-wire socket without a grounding wire is prone to static electricity, and solid particles in the air are easy to accumulate at the socket mouth, and sometimes you can feel static electricity. Using a two-wire socket without a grounding wire, the socket mouth accumulates too much air Solid particles are likely to cause adverse consequences such as electric leakage, fire or even explosion; in addition, the traditional plug connector is easy to fall off after the plug is inserted, which seriously affects the normal use of the plug connector
