Display connector and fabrication method thereof

Abstract

The invention discloses a display connector and a fabrication method thereof. The display connector comprises an insulation base, a terminal group, an insulation rear plug and a metal shell, wherein the insulation rear plug is used for limiting and hot-melting wrapping the terminal group. In the display connector, the insulation rear plug is additionally arranged at a rear end of the insulation base, a second contact part surface of a lower-layer terminal is in contact with a bottom surface of the insulation rear plug by the insulation rear plug, a first contact part surface of an upper-layer terminal is flush with a boss surface of the insulation rear plug, the insulation rear plug is subjected to hot melting by a jig to form plastic barriers so as to wrap contact parts of the upper-layer terminal and the lower-layer terminals and achieve a fixing effect, the coplanarity and the alignment degree of welding parts of the upper-layer terminal and the lower-layer terminal can be effectively ensured, high stability is achieved, terminal pins are not needed to be adjusted by manual, and the production efficiency is improved; and moreover, after the upper-layer terminal and the lower-layer terminal are assembled, a first pin part and a second pin part are staggered vertically, and crosstalk can be enabled not to be generated in high-frequency signal transmission of the upper-layer terminal and the lower-layer terminal very well.

Description

Technical field: [0001] The invention relates to the technical field of connector products, in particular to a display connector. Background technique: [0002] The Display connector is widely used in data transmission of personal computers and servers. It is an interface specification approved by the Video Electronics Standards Association (VESA). The Display connector aims to surpass the DVI and HDMI interface technologies in several fields and provide a high-bandwidth Show interface. [0003] The display connector in the prior art basically includes: a base, an upper row of terminals installed on the base, a lower row of terminals, and a metal metal shell covering the outside of the base. The upper row of terminals of the traditional display connector After the contact portion with the lower row of terminals is inserted into the base, the pins of the upper row of terminals and the lower row of terminals protrude from the insulating base and are embedded in the slots form...

AI Technical Summary

Problems solved by technology

However, after the upper row of terminals and the lower row of terminals are assembled, the pins are staggered with each other, the end faces of the two pins are not on the same plane, and the pins of the upper row of terminals and the lower row of terminals are staggered, and There is no plastic coating on the pin part of the terminal, and the fixing effect of the electronic pin part is not good. Yes, the coplanarity and positive position of the terminal are not easy to guarantee. Sometimes the pin part of the terminal needs to be manually adjusted, and the stability is not good; Some manufacturers have improved the above-mentioned display connectors by fixing the pins of the terminal group installed on the insulating base by hot melting, and wrapping the pins of the terminal group by plastic hot melting. However, since the end faces of the above-mentioned two pins are not on the same plane, it is easy to cause glue flow when hot-melting, and the hot-melting effect is poor, and the pins of the hot-melt front terminals are not fixed. , the lead part of the terminal is prone to deviation during the heat-melting process, and the terminal feet will be skewed after heat-melting
