(1)板状をなす雄端子と、前記雄端子に接続される雌端子と、を備え、前記雌端子は、前記雄端子が挿入されて配置される雄端子挿入隙間を隔てて対向配置された第1壁部と第2壁部を有し、前記雄端子は、前記雄端子挿入隙間への挿入方向に交差する方向である板幅方向の両側に、前記雄端子の板厚方向の一方側に傾斜する一対の傾斜部を有し、前記第1壁部は、前記雄端子の前記板厚方向の一方側の面に対向し、前記第2壁部に向かって突出する弾性接触部を有し、前記弾性接触部は、前記第2壁部から離隔する方向に弾性変形可能で前記雄端子を前記第2壁部に向かって付勢するものであり、前記第2壁部は、前記雄端子の前記板厚方向の他方側の面に対向しており、前記雄端子の前記一対の傾斜部にそれぞれ接触する一対の第1突状接点部を有している、端子ユニットである。
(6)上記(1)から上記(5)のいずれかに記載の端子ユニットにおいて用いられる雌端子である。本開示の雌端子によれば、上記(1)から上記(5)のいずれかに記載の端子ユニットにおいて用いられることから、上記(1)から上記(5)の端子ユニットが享受しうる作用効果を同様に有することができる。それゆえ、雌端子に対する雄端子の板幅方向での変位を抑制することができ、振動等による雌雄端子間の微摺動摩擦やそれによる接触抵抗値の増大を抑制することができる。
(7)上記(1)から上記(5)のいずれかに記載の端子ユニットにおいて用いられる雄端子である。本開示の雄端子によれば、上記(1)から上記(5)のいずれかに記載の端子ユニットにおいて用いられることから、上記(1)から上記(5)の端子ユニットが享受しうる作用効果を同様に有することができる。それゆえ、雌端子に対する雄端子の板幅方向での変位を抑制することができ、振動等による雌雄端子間の微摺動摩擦やそれによる接触抵抗値の増大を抑制することができる。
本開示の端子ユニットおよび当該端子ユニットに用いられる雌端子と雄端子の具体例を、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、特許請求の範囲によって示され、特許請求の範囲と均等の意味およ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、本開示の実施形態1の端子ユニット10について、図1から図5を用いて説明する。端子ユニット10は、雄端子12と雌端子14とを備えている。そして、雄端子12が雌端子14に挿入されて相互に接触することで、雄端子12と雌端子14とが電気的に接続されるようになっている。なお、端子ユニット10は、任意の向きで配置することができるが、以下では、上下方向,左右方向,前後方向を、図中に示す上下方向,左右方向および前後方向を基準として説明する。また、複数の同一部材については、一部の部材にのみ符号を付し、他の部材については符号を省略する場合がある。
雄端子12は、全体として板状をなしており、図示しない平板金具を用いて構成されている。平板金具は矩形状を有している。雄端子12は、所定の板幅寸法(図5中の左右方向寸法)および板厚寸法(図5中の上下方向寸法)を有しており、ストレートに延びている。なお、雄端子12において、挿入方向の先端側の端部(図4中、後方側)は、先細形状である。雄端子12は、導電性を有しており、例えば銅、銅合金、アルミニウム、アルミニウム合金等の電気抵抗の低い金属により形成される。
雌端子14は、例えば図2や図4に示すように、内部に前後方向に開口する雄端子挿入隙間38を有する箱状の本体部20と、図示しない電線の芯線が固着される電線接続部22と、を含んで一体的に構成されている。より詳細には、雌端子14は、導電性を有しており、且つプレス加工や打抜き加工等が可能な種々の金属材料、例えば真鍮や銅、銅合金、アルミニウム、アルミニウム合金等を用いて形成されている。
本体部20は略箱状に形成されており、上下方向に対向する第1壁部26,第2壁部28と、左右方向に対向する一対の側壁30,32と、を備えている。加えて、本体部20は、後述する弾性接触部40の突出先端部を前方から覆う保護壁34と、弾性接触部40の上方への過度の変位を防止する防止壁36と、を備えて構成されている。
以上、本開示の具体例として、実施形態1について詳述したが、本開示はこの具体的な記載によって限定されない。本開示の目的を達成できる範囲での変形、改良等は本開示に含まれるものである。例えば次のような実施形態の変形例も本開示の技術的範囲に含まれる。
