Description

差動訊號電連接組件及可傳送差動訊號的電路板Differential signal electrical connection component and circuit board capable of transmitting differential signal

本發明有關於一種電連接器，尤指一種可傳送差動訊號的電連接器。The invention relates to an electrical connector, in particular to an electrical connector capable of transmitting differential signals.

近年來 Mini PC、平板電腦及薄型筆電於市場上需求日益增加，其應用層面包含了物聯網需求、廣告看板、及數位家庭劇院電腦。由於近年來高畫質輸出的普及，使得消費者對於透過PCIE插槽來擴充顯示卡產生極大需求。礙於PCIE頻寬高達8GHz，PCI-SIG針對其傳輸訊號品質有其要求及規範。目前市面上所開發之轉接線及接頭均礙於無法達到PCI-SIG制訂的訊號規範皆限制在舊有規範所定義之插槽及排線的規劃，其尺寸及方向性之設計均不適用於目前需要的應用且成本過高。In recent years, Mini PCs, tablets, and thin laptops have been increasingly in demand in the market, and their applications include IoT requirements, billboards, and digital home theater computers. Due to the popularity of high-quality output in recent years, consumers have a great demand for expansion of graphics cards through PCIE slots. Due to the PCIE bandwidth up to 8GHz, PCI-SIG has its own requirements and specifications for the quality of its transmission signals. The patch cords and connectors currently developed on the market are unable to meet the signal specifications formulated by PCI-SIG. They are limited to the slot and cable planning defined by the old specifications, and their size and directionality design are not applicable. For the applications currently needed and the cost is too high.

另一方面，當基板上預留給PCIE插槽的空間較大時，相對使得連接於PCIE插槽的傳輸線寬度變寬而影響主機機殼的設計，並不適用於微型電腦、平板電腦及薄型筆記型電腦之應用。On the other hand, when the space reserved for the PCIE slot on the substrate is relatively large, the width of the transmission line connected to the PCIE slot is relatively widened, which affects the design of the host case. It is not suitable for microcomputers, tablet computers and thin-type computers. The application of notebook computer.
