Description

本考案は、ケーブル間での干渉を低減し伝送特性を向上したＬＡＮケーブルに関するものである。 The present invention relates to a LAN cable that reduces interference between cables and improves transmission characteristics.

従来からパーソナルコンピュータや周辺機器、ローカルネットワーク内での情報伝達ケーブルとしてＬＡＮ（ＬｏｃａｌＡｒｅａＮｅｔｗｏｒｋ）ケーブルが広く用いられている。そして、このＬＡＮケーブルは通常２芯のツイストペアケーブルが４本で構成され、合計８芯のケーブルとなっている。また、ＬＡＮケーブルは複数のカテゴリに分類されており、カテゴリが上がる程、伝送周波数の高周波化による通信速度の高速化が図られている。しかしながら、伝送周波数が高周波化するとケーブル間での信号の干渉等の問題が発生するため、特に高カテゴリのＬＡＮケーブルではこれら干渉やノイズに対する様々な対策が施されている。例えば、カテゴリ７のＬＡＮケーブルでは各ツイストペアケーブルを個別にホイル状のシールドで覆い、互いの信号伝達における干渉を低減して高周波伝送の劣化を抑制している。また、これに関連して、例えば下記［特許文献１］には安価で伝送特性に優れたＬＡＮケーブルに関する発明が開示されている。 Conventionally, LAN (Local Area Network) cables have been widely used as information transmission cables in personal computers, peripheral devices, and local networks. This LAN cable is usually composed of four 2-core twisted pair cables, for a total of 8-core cables. In addition, LAN cables are classified into a plurality of categories, and the higher the category, the higher the communication speed by increasing the transmission frequency. However, when the transmission frequency becomes high, problems such as signal interference between cables occur. Therefore, especially in high-category LAN cables, various measures against such interference and noise are taken. For example, in a category 7 LAN cable, each twisted pair cable is individually covered with a foil-shaped shield to reduce interference in signal transmission with each other and suppress deterioration of high-frequency transmission. In connection with this, for example, the following [Patent Document 1] discloses an invention relating to a LAN cable that is inexpensive and has excellent transmission characteristics.

しかしながら、如何に干渉対策を施したとしても、１本のケーブル内に４組８芯の導体が存在している限り、互いの干渉を防止するには限界があり、更なる改善が望まれる。 However, no matter how the interference countermeasures are taken, as long as 4 sets of 8-core conductors exist in one cable, there is a limit to prevent mutual interference, and further improvement is desired.

本考案は上記事情に鑑みてなされたものであり、ケーブル間の信号の干渉を低減し伝送特性に優れたＬＡＮケーブルの提供を目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a LAN cable having excellent transmission characteristics by reducing signal interference between cables.

A third twisted pair cable having one end connected to at least the 4-pin terminal and the 5-pin terminal of the LAN connector on one side, and a fourth twisted pair cable having one end connected to the 7-pin terminal and the 8-pin terminal of the LAN connector on at least one side. In a straight or cross LAN cable with twisted pair cable and
The first twisted pair cable, the second twisted pair cable, the third twisted pair cable, and the fourth twisted pair cable were individually used as four signal cables, and the LAN connectors were connected to both ends of the four signal cables. A LAN cable characterized by that.
