"[0056] As shown in the graph, for the compression rate of 80%, the compression force is maintained at 300 kPa or higher even after 120 hours at 120° C. On the other hand, for the compression rate of 90%, the stress is relaxed along with the retention time and decreases to approximately 50 kPa after 120 hours. The compression force of 50 kPa or lower increases the risk of leaking, since the pressure overcomes the compression force at the time of a leaking test under approximately 50 kPa. That is, if the covering material alone fails to have enough compression force, it means that the wire covering fails to keep enough surface pressure under compression. Usually, an electric wire and a terminal are crimped by caulking in a vertical direction (in one axial direction), creating a stress distribution. This allows leaking from the regions in which the compression stress is small, such as the side region of the electric wire, and thus the compression rate is required to be smaller than that in the test with the covering material alone. The results of the air-leaking test for the wire harness after crimping will be described later. "2018175574

「[0045] 図に示すように、圧縮率が８０％の場合、１２０°Cで１２０時間後においても、３００ｋＰａ以上の圧縮力を維持する。一方、圧縮率が９０％では、保持時間とともに応力が緩和されて、１２０時間後には、５０ｋＰａ程度まで減少する。圧縮力が５０ｋＰａ以下となると、５０ｋＰａ程度のリークテストをした際に、圧力に対して圧縮力が負けて、リークする危険性が増す。つまり被覆材単体の状態で十分な圧縮力が得られない場合は、電線被覆を圧縮した時に十分な面圧を保てないと言える。一般に、電線と端子を圧着する場合は、上下方向（一軸方向）から加締めるため、応力分布ができ、電線の側面領域など圧縮応力が小さい領域からリークしやすい傾向となるため、被覆材単体での試験の場合に比べて圧縮率の値を小さくする必要がある。なお、圧着後のワイヤハーネスのエアリーク試験結果については後述する。  」

"In this cylindrical crimping portion 140, the cylindrical crimping portion 140 is caulked with the end portion of the conductor wire 102 inserted into the insertion hole 141, thereby causing the cylindrical crimping portion 140 to be subjected to plastic deformation and crimped with the covering portion and the conductor of the conductor wire 102. As a result, the cylindrical crimping portion 140 and the conductor of the conductor wire 102 are electrically connected. "

"Background Art

Wire harnesses are often used for internal wiring of automobiles. A wire harness is a module in which a plurality of coated wires are assembled in accordance with in-vehicle wiring specifications. Terminals for connection (hereinafter referred to as crimp terminals) are crimped to ends of each of the coated wires. When connecting a crimp terminal to a wire end of the wire harness, electrical connection between the wire end and the crimp terminal is provided by stripping the insulating coating layer at a wire end to expose the core wire, and swaging and crimping a core wire barrel of the crimp terminal to the exposed portion of the core wire. The connecting portion between the crimp terminal and the wire end is sealed with resin so as to prevent corrosion of the core wire due to ingress of moisture into the wire from the connecting portion (see Japanese Laid-Open Patent Publication No. 2001-167821 and Japanese Laid-Open Patent Publication No. 2012-069449, for example).

「[0002] 自動車の車内配線にはワイヤハーネスが多用される。ワイヤハーネスは、車内配線の仕様に合わせて複数の被覆電線を集合部品化したものである。各被覆電線の端末には、接続用の端子（以下、圧着端子という。）が圧着されている。圧着端子をワイヤハーネスの電線端末に接続する場合、電線端末の絶縁被覆層を皮剥ぎして芯線を露出させ、芯線露出部に圧着端子の芯線バレルを加締め圧着することにより、電線端末と圧着端子との電気的接続がなされる。そして、圧着端子との接続部から電線内への水分の浸入による芯線の腐食を防止するべく、圧着端子と電線端末との接続部が樹脂封止される（例えば、特許文献１，２参照）。 」
