Description

Simple grounding device for monitor interface

Technical Field

The invention relates to the field of monitors, in particular to a simple grounding device for a monitor interface.

Background

With the rapid development of the global electronics industry, a series of economic losses caused by electrostatic discharge damage are serious. The exposed interfaces of various devices are attacked by human static electricity at any time, so that the devices are out of order and even the devices are damaged. As engineering technicians, effective technological means are adopted to control and prevent electrostatic damage, and loss caused by static electricity is reduced to the maximum extent.

Usually, the monitor is provided with a grounding post connected with the ground to discharge static electricity. The grounding column is generally arranged on a grounding metal plate inside the monitor, and how to connect the exposed interface with the grounding metal plate is a general technical method for solving the problem of interface grounding. Mass production can customize different contact pieces to connect the interface with the grounding metal plate according to different interfaces, but this will increase the cost for the initial development and small-scale production. For this case, a simple grounding device of low cost can address this application requirement.

Disclosure of Invention

In order to overcome the defects of the grounding device for the exposed interface of the monitor, the invention aims to provide the simple grounding device for the monitor interface, which is used for grounding connection of the exposed interface of the monitor.

The invention provides a simple grounding device for a monitor interface.

The grounding column, the grounding metal plate and the spring piece are assembled into a whole through the screw and the nut, and the circuit board welded with the interface is installed on the grounding metal plate.

The spring of the spring piece is pressed on the interface circuit board. The spring can compress to adapt to interfaces with different heights and functions. Static electricity reaches the grounding column through the interface, the spring and the grounding metal plate and is released to the ground, so that electronic components on the circuit board are prevented from being damaged.

The invention has the advantages that: the spring of the spring piece can be freely compressed, and one spring piece can be suitable for different interfaces. The spring leaf is taken from the negative pole piece of No. 1 dry battery, and this is the quick purchase of standard part according to the demand, has alleviateed development cost greatly, has shortened the customization delivery period.
