Abstract
Description
最初に本開示の実施態様を列記して説明する。
本開示の配線部材の具体例を、以下に図面を参照しつつ説明する。なお、本開示はこれらの例示に限定されるものではなく、請求の範囲によって示され、請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。
以下、実施形態1にかかる配線部材について説明する。各図面では、説明の便宜上、構成の一部を誇張又は簡略化して示す場合がある。また、各部分の寸法比率については各図面で異なる場合がある。また、本明細書における「垂直」は、厳密に垂直な状態のみでなく、概ね垂直な状態も含まれる。概ね垂直とは、例えば2つの方向の成す角度が80度以上90度未満、好ましくは85度以上90度未満の状態である。また、本明細書における「平行」は、厳密に平行な状態のみでなく、概ね平行な状態も含まれる。概ね平行とは、例えば2つの方向の成す角度が10度以下、好ましくは5度以下の状態である。
図5はツイスト線20を融着するための準備工程を示す説明図である。図6はツイスト線20の融着工程を示す説明図である。
このように構成された配線部材10によると、横並び融着部分50を含む第1半周期区間28Aの長さD1が、第1半周期区間28Aの隣の第2半周期区間28Bの長さD2R、D2Lよりも長いことによって、横並び融着部分50を長くすることが容易となる。これにより、ツイスト線20をより強固にベース部材30に融着固定することができる。
これまで、横並び融着部分50において、第1線状伝送部材21Aと第2線状伝送部材21Bとが並列方向に離れているものとして説明されたが、このことは必須の構成ではない。横並び融着部分50において、第1線状伝送部材21Aと第2線状伝送部材21Bとが並列方向に接していてもよい。
