Abstract

A VGA connector comprises a plurality of power supply terminals, a plurality of signal terminals, a plurality of grounding terminals and a plurality of leads, wherein the plurality of power supply terminals are connected with a power supply, the plurality of signal terminals are used for transmitting signals, the plurality of grounding terminals are used for grounding, and the plurality of leads are connected with the plurality of signal terminals correspondingly one by one. One end of each of the leads is electrically connected with another VGA connector, and an electromagnetic interference suppression component is electrically connected between the other end of each of the leads and the corresponding signal terminal. According to the VGA connector, electromagnetic interference suppression components are arranged to absorb interference signals entering the VGA connector, so that interference signals can be suppressed.

Description

technical field [0001] The invention relates to a video graphic array (Video Graphic Array, VGA) connector. Background technique [0002] VGA connectors have been widely used in various electronic products, such as monitors, computer hosts, etc. However, when conducting electromagnetic compatibility tests on electronic products, external interference signals can easily enter the interior of electronic products through the VGA connector. Contents of the invention [0003] In view of this, it is necessary to provide a VGA connector capable of suppressing interference signals. [0004] A VGA connector, which includes a plurality of power terminals for connecting with a power supply, a plurality of signal terminals for transmitting signals, a plurality of grounding terminals for grounding, and a plurality of terminals correspondingly connected with the plurality of signal terminals. wire. One end of each wire is electrically connected to another VGA connector, and an electr...
