LED signal transmission interface and plug thereof

Abstract

The invention provides a plug of an LED signal transmission interface, comprising a main body part and a conductor part. The main body part is provided with an inside groove, and the conductor part is provided with a pipe sleeve and a contact pin arranged on the pipe sleeve. The pipe sleeve of the conductor part is connected to the inner groove of the main body part through more than two buckle structures, and the buckle structures are distributed opposite to each other at the two sides of the pipe sleeve. The invention also provides an LED signal transmission interface provided with the plug. In the LED signal transmission interface and the plug thereof, the more than two buckle structures are arranged between the plug and the inner groove and distributed opposite to each other at the two sides of the pipe sleeve, therefore, the pipe sleeve can be effectively fixed in the inner groove without loosening, the contact pin on the pipe sleeve and the main body part of the plug can be firmly connected, and excellent signal transmission performance between the contact pin and a socket is further ensured.

Description

technical field [0001] The invention relates to an interface device, in particular to an LED signal transmission interface of an LED liquid crystal display panel and a plug thereof. Background technique [0002] LVDS (Low Voltage Differential Signaling) interface has been widely used in telecommunications, communications, and consumer electronics due to its high efficiency, low power consumption, high speed, low cost, low clutter interference, and high resolution support. , automobiles, medical instruments and other fields. At present, LED products on the market generally use this low-power, low-noise low-voltage differential signal receiver LVDS as the signal transmission interface in the form of connecting the liquid crystal display panel to the system motherboard. [0003] The transmission interface includes docking plugs and sockets. A set of LED signal transmission interfaces are respectively provided on the main board end and the LED display end, wherein the two socke...

AI Technical Summary

Problems solved by technology

However, the sleeve 122 is only connected and fixed to the bayonet 1111 of the inner groove 111 through a protruding hook 1221, and only one side of the sleeve 122 is buckled in the inner groove 111. During the transportation, installation or maintenance of the product, Irregular shaking will inevitably occur. Because there is a certain gap between the sleeve 122 and the inner groove 111, the protruding hook 1221 is easy to fall off from the bayonet 1111, causing the pin 121 to fall out of its original position, and the contact with the pin of the socket is poor. Impedance changes, affecting the display of the whole machine

[0005] In addition, because the socket slot is shallow and the contact line between the pin and the pin is short, during the installation process of the product, once the plug is not inserted in place, it will lead to poor contact of the product and poor signal transmission; and there is no card between the plug and the socket. Buckle structure, the irregular shaking of the product during transportation will also cause the plug to fall off from the socket, and on the other hand, it will also increase the defective rate of product contact and conduction

[0006] Furthermore, most of the existing sockets are in-line sockets (the plugging direction of the LED signal transmission interface is perpendicular to the plug board). Strong, poor contact between the plug and the socket; on the other hand, the in-line socket takes up a lot of space and cannot be used on LED displays with limited space, and its use is limited, and the shell of this in-line socket is made of plastic. The ground wire on the motherboard side cannot be connected to the ground wire on the display side, and the EMC (Electro-Magnetic Compatibility) effect is not good
