Abstract

本創作為一種線纜，其包括：一對芯線，同時包覆在一對所述芯線之外的押出成型的絕緣層；包覆所述絕緣層的遮罩層，以及包覆所述遮罩層的外被；一對所述芯線並排縱向排列並相互接觸在一起。

Description

線纜
本創作涉及一種線纜，尤其涉及一種用於傳輸高頻信號的高速信號線纜。
現有技術中的高速信號線纜，其通常包括一對信號芯線、圍繞在芯線之外的金屬遮罩層、包覆在金屬遮罩層外的絕緣外皮及緊鄰金屬遮罩層的接地線（可一對也可單個）,一對信號芯線各自均包括內絕緣層及被包覆於所述內絕緣層內的內導體。每個信號芯線的內導體和內絕緣層分別一體成型後再將兩信號線並排排列後包覆於金屬遮罩層內。因兩獨立成型的信號芯線之間位置相對不固定，存在電氣特性不穩定的情況。請參照2018年8月7日公開的中國發明專利第CN108376580A號，其揭示了一種線纜，其包括一對信號芯線、圍繞在芯線之外押出成型的絕緣層，包覆在絕緣層外的金屬遮罩層、包覆在金屬遮罩層外的絕緣外皮及緊鄰金屬遮罩層的接地線，其兩根芯線之間距離較遠，芯線之間的位置相對不固定，線材整體的空間大。
是以，有必要提供一種信號傳輸穩定、可靠且製造簡單的線纜，在保證整體阻抗匹配的情況下，儘量減小兩導體間的間距，進而減小整體線材的外徑，並且使得芯線之間位置相對固定。
目的在於：提供一種線纜，該線纜在保證阻抗匹配的前提下，減小導體間距，從而減小整體線材的外徑。
為達成上述目的，本創作可採用如下技術方案：
一種線纜，其包括：一對芯線，同時包覆在一對所述芯線之外的押出成型的絕緣層；包覆所述絕緣層的遮罩層，以及包覆所述遮罩層的外被；一對所述芯線並排縱向排列並相互接觸在一起。
與習知技術相比，本創作具有如下功效：兩芯線相互接觸使得其之間的位置相對固定，同時包覆在兩芯線之外的押出成型的絕緣層，使得芯線外變成一個整體絕緣結構，在後續加工中兩芯線位置也不容易發生變動，這樣保證整體阻抗和兩芯線相對位置不變的情況下，相互接觸的兩芯線減小了兩導體間的間距，從而也減小了整體線材的外徑。同時本創作線材具有大於40GHz信號頻率的高速訊號傳輸能力。
為便於更好的理解本創作的目的、結構、特徵以及功效等，現結合附圖和具體實施方式對本創作進一步說明。
請參閱第一圖，係本創作線纜100的第一實施例。所述線纜從內向外依次包括芯線10、絕緣層20、遮罩層30、地線40及外被50。所述絕緣層20包覆於所述芯線10之外，所述遮罩層30包覆於所述絕緣層20之外，所述外被50包覆於遮罩層30之外。所述地線40位於遮罩層30和外被50之間。
本實施例中所述芯線10包括兩根，其相互接觸並在縱向方向上延伸。每根所述芯線10分別包括內導體1及包覆內導體1的內絕緣層2，所述內導體1用於傳輸高速信號。兩根所述芯線10的兩內絕緣層2均分別押出成型包覆各自的內導體1。所述內導體1可為銅內導體、鍍銀銅內導體、鍍錫銅內導體中的一種。所述內絕緣層包括PP（中文全稱：聚乙烯）、PE (中文全稱：聚丙烯)、鐵氟龍（又稱：聚四氟乙烯)、發泡 PP、發泡 PE、發泡鐵氟龍中任意一種。兩根所述芯線10的內絕緣層2相互緊挨在一起。相互緊挨在一起的兩根所述芯線10外部包覆有同時押出成型的絕緣層20。這樣所述絕緣層20與芯線10之間無空氣間隙。緊鄰著的兩根芯線10使得兩內導體1的之間隔了兩個絕緣層20的厚度，這樣兩根內導體1的相互位置相對固定，這樣在保證內導體1相對位置不變的前提下減小了兩內導體1之間的間距，進而減整體線纜的外徑。並且所述絕緣層20包覆兩根所述芯線10後形成一個整體的絕緣結構，以保證後續的加工製造過程中兩芯線10的相對位置不會變動。所述絕緣層20可為PP、PE、鐵氟龍、發泡PP 、發泡PE、發泡鐵氟龍中任意一種。所述接地線40為兩根，兩根所述接地線40位於所述遮罩層30的左右兩側。所述遮罩層30包括鋁箔(AL/PET)、雙面鋁箔(AL/PET/AL)、銅箔(Cu/PET)、雙面銅箔(Cu/PET/Cu)、半導電包帶及鍍銀銅箔中任意一種。所述遮罩層30以縱向包覆的包覆方式包覆於絕緣層20外或以螺旋纏繞的方式包覆於絕緣層20外，當然。所述外被層50可設置為一層或多層，其材質可以為PET (中文全稱：聚對苯二甲酸乙二醇脂)包帶。所述外被50纏繞包覆在所述遮罩層外。
請參閱第二圖，係本創作線纜100’的第二實施例，所述線纜100’包括芯線10’、包覆所述芯線的絕緣層20’、包覆所述內絕緣層的遮罩層30’、及包覆所述遮罩層30’的外被50’及設置在所述遮罩層30’與外被50’之間的地線40’。與第一實施例相比本實施例中所述地線40’為一根，其設置在所述遮罩層30’上側兩根芯線中間靠上的位置。
本創作通過中押出芯線後，再增加同時包覆兩芯線的第二次押出，並且兩芯線相互接觸使得其內導體的位置相對固定，一次成型在兩芯線外的絕緣層使得線纜變成實心整體絕緣結構，再後續加工中兩芯線位置不容易發生變動，另外本創作線纜在保證整體阻抗不變的情況下，減小了兩導體間的間距，進而減小了整體線材的外徑。本創作線纜具有大於40GHz信號頻率的高速資料傳輸能力。為線纜高頻特性的提高和改善提供了較多的選擇。
綜上所述，本創作符合新型專利要件，爰依法提出專利申請。惟，以上所述者僅為本創作之較佳實施例，本創作之範圍並不以前述實施例為限，舉凡熟習本案技藝之人士援依本創作之精神所作之等效修飾或變化，皆應涵蓋於以下申請專利範圍內。
