Description

本発明は端子金具および該端子金具を取り付けた電線の接続構造に関し、詳しくは、雌雄の区別のない端子金具の構造を簡素化しつつ、優れた電気接触性能を保持するものである。   The present invention relates to a terminal fitting and a connection structure of an electric wire to which the terminal fitting is attached. Specifically, the present invention simplifies the structure of a terminal fitting with no distinction between males and females and maintains excellent electrical contact performance.

従来、電線同士の接続は、一方の電線端末に接続された雄端子金具と、他方の電線端末に接続された雌端子金具との嵌合により行われている。雄端子金具1は、例えば図7(A)に示すように、被覆バレル2aや芯線バレル2bからなる電線接続部2に連続してタブ状の電気接触部3を突出させている一方、雌端子金具4は例えば図7(B)に示すように、電線接続部5に連続して、前記雄端子金具1のタブ状の電気接触部3を受け入れて接触可能とする角筒状の電気接触部6を突出させている。   Conventionally, connection between electric wires is performed by fitting a male terminal fitting connected to one electric wire end and a female terminal fitting connected to the other electric wire end. For example, as shown in FIG. 7A, the male terminal fitting 1 has a tab-shaped electrical contact portion 3 protruding continuously from a wire connecting portion 2 composed of a covering barrel 2a and a core wire barrel 2b. For example, as shown in FIG. 7 (B), the metal fitting 4 is a rectangular tube-shaped electric contact portion that is continuous with the wire connecting portion 5 and receives the tab-like electric contact portion 3 of the male terminal fitting 1 so as to be contactable. 6 is projected.

しかし、前記構成の端子金具では、雄端子金具1と雌端子金具4の使い分けが必要となると共に、形状の異なる雄端子金具1および雌端子金具4を収容するハウジングの使い分けも必要となるため、電線接続に必要な部品の種類が増大するという問題がある。   However, in the terminal fitting having the above-described configuration, it is necessary to use the male terminal fitting 1 and the female terminal fitting 4 separately, and it is also necessary to use different housings for housing the male terminal fitting 1 and the female terminal fitting 4 having different shapes. There exists a problem that the kind of components required for an electric wire connection increases.

そこで、特開平7−288148号公報(特許文献1)では、図8に示すように、平板状の雄機能部8と、雄機能部8が嵌合可能な筒形状の雌機能部9とを平行配置した端子金具7を提案し、同じ構造を有する端子同士の接続を可能としている。   Therefore, in Japanese Patent Application Laid-Open No. 7-288148 (Patent Document 1), as shown in FIG. 8, a flat male functional portion 8 and a cylindrical female functional portion 9 into which the male functional portion 8 can be fitted are provided. The terminal fitting 7 arranged in parallel is proposed, and the terminals having the same structure can be connected to each other.

特開平7−288148号公報JP 7-288148 A

前記構造の端子金具7を用いることにより、従来のような雄端子金具と雌端子金具の使い分けは不要となるものの、雄機能部8と雌機能部9とを平行配置しているため端子金具7の幅が広がって大型化すると共に、端子金具7の構造も複雑化するという問題がある。   By using the terminal fitting 7 having the structure described above, it is not necessary to separately use the male terminal fitting and the female terminal fitting as in the prior art. However, since the male functional portion 8 and the female functional portion 9 are arranged in parallel, the terminal fitting 7 is provided. However, the structure of the terminal fitting 7 is complicated.

また、本発明は、前記端子金具を、互いに電気接続する一対の第1電線と第2電線をそれぞれ前記電線接続部に接続し、前記電気接触部を上下逆方向に配置して、前記第1電気接触部と第2電気接触部とを互いに接触して電気接続する構成としている電線の接続構造を提供している。
具体的には、前記第1電線に接続した前記基板部の上面を上向き、前記第2電線に接続した前記基板部の上面を下向きとし、前記第1電線の第1電気接触部に第2電線の第2電気接触部が押し当てられて電気接触すると共に、前記第1電線の第2電気接触部を第2電線の第1電気接触部に押し当てて電気接触する構成としている。
