VGA plug for computer

Abstract

The invention belongs to the technical field of computer accessories, and particularly relates to a VGA plug for a computer. The VGA plug comprises a mounting plate, a mounting block, screws, a plug-in opening, a plugging pipe and a friction mechanism, the mounting block is fixedly connected into the wall of the mounting plate, the mounting plate is rectangular, the screws are rotationally connected into the two end walls of the mounting plate, and the mounting plate is fixedly connected with the display card through the screws; the outer end of the mounting block protrudes out of the mounting plate, the interior of the mounting plate is hollow, and an insertion opening is formed in the front end of the mounting plate; a plug-in pipe is horizontally arranged on the inner side of the plug-in opening; the front end of the plug-in pipe is fixedly connected to the inner wall of the front end of the mounting block, and the inner end of the plug-in pipe is connected with the display card; when the port pin is inserted into the plug-in pipe, extrusion force actually exists on the friction tube, so that the friction tube slides into the wall of the elastic plate, the outer surface of the port pin can be ground by the friction tube when the elastic plate shrinks, and the rust stain on the port pin can be further cleaned.

Description

technical field [0001] The invention belongs to the technical field of computer accessories, in particular to a VGA plug for a computer. Background technique [0002] VGA (Video Graphics Array) is a computer display standard proposed by IBM in 1987 using analog signals. The VGA interface is a special interface for the computer to output data using the VGA standard. The VGA interface has a total of 15 pins, divided into 3 rows, with 5 holes in each row. It is the most widely used interface type on graphics cards, and most graphics cards have this type of interface. It transmits red, green, blue analog signals and sync signals (horizontal and vertical signals). [0003] In the computer field, the VGA connector is used to connect the computer graphics card and the monitor in order to realize the transmission of high-definition signals. However, in some rainy areas all the year round, the electronic components in the computer are easily rusted due to moisture due to the humid ...

Problems solved by technology

[0003] In the computer field, the VGA connector is used to connect the computer graphics card and the monitor in order to realize the transmission of high-definition signals. However, in some rainy areas all the year round, the electronic components in the computer are easily rusted due to moisture due to the humid air all the year round. , greatly reducing the service life, and among them, the VGA connector is unavoidable. Once the VGA interface is damp and rusted, the connection strength between it and the graphics card will be affected and reduced, which will cause common abnormal black screens and flower screens And so on, and the way to solve this kind of problem is to pull out the VGA interface and polish the pins inside to remove the rust stains on the surface. This operation is usually done manually, which is not only time-consuming and labor-intensive, but also easy As a result, the VGA interface has been pulled out all the year round, causing the interface to become loose
