圧着端子10が取り付けられる対象となる絶縁電線9は、長尺な導体である芯線91と、その芯線91の周囲を覆う絶縁体である絶縁被覆92と、を有する電線である。通常、芯線91は、細い導体からなる複数の素線が撚り合わされた撚り線である。しかしながら、芯線91が単線であることも考えられる。
圧着端子10は、直線方向に沿って一列に並んで形成された、被覆圧着部20、第一連結部30、芯線圧着部40、第二連結部50及び接点部60を備えている。
被覆圧着部20は、曲がって形成された板状の部分であり、絶縁電線9に圧着される前の状態において、絶縁電線9における絶縁被覆92の部分が挿入される溝を形成している。被覆圧着部20は、その溝の内側に挿入された絶縁被覆92の部分の周囲に沿って曲げられることにより、絶縁被覆92の部分に対して圧着される。
接点部60は、圧着端子10の接続相手となる不図示の相手側端子と嵌り合うことによって相手側端子と直接接触する部分である。図1に示される接点部60は、相手側端子が嵌め入れられる孔が形成された筒状の部分である。なお、接点部60が、相手側端子の端子挿入孔に嵌め入れられる棒状の導体である場合もある。
