Description

本発明は、主に基板対電線、電線対電線の接続に使用する圧接方式の電線用コネクタに関する。   The present invention relates to a pressure contact type wire connector used mainly for connection between a substrate and a wire and a wire to wire.
従来、基板対電線、電線対電線の接続には、圧接端子を用いた圧接方式の電線用コネクタが広く使用されている。   2. Description of the Related Art Conventionally, pressure connection type wire connectors using pressure contact terminals have been widely used for connection between a substrate and a wire and a wire to wire.
この圧接方式の電線用コネクタは、被覆電線が接続される導電金属製の複数の圧着端子と、圧着端子が保持される絶縁樹脂製のハウジングとを備えたプラグを備え、そのプラグをソケットに連結することにより、圧着端子の端子接続部がソケットの接続端子と接触し、両者を電気的に接続させるようになっている。   This pressure contact type wire connector includes a plug having a plurality of conductive metal crimp terminals to which covered wires are connected and an insulating resin housing to hold the crimp terminals, and connects the plug to the socket. By doing so, the terminal connection portion of the crimp terminal comes into contact with the connection terminal of the socket, and both are electrically connected.
圧接端子は、一方の端縁に開口したスリット状の圧接溝が形成された圧接板部を備え、圧接溝内に被覆電線を電線軸方向と交差する方向から圧入させることにより、圧接溝の内側に形成された圧接刃で外周被覆を突き破るとともに、圧接溝内に被覆電線の芯線を挟持し、圧接端子と被覆電線とが接触するようになっている。   The press contact terminal is provided with a press contact plate portion formed with a slit-like press contact groove opened at one end edge, and press-fit the covered electric wire into the press contact groove from the direction intersecting the electric wire axial direction. The outer peripheral sheath is pierced by the press contact blade formed on the outer periphery, and the core wire of the covered electric wire is sandwiched in the press contact groove so that the press contact terminal and the covered electric wire come into contact with each other.
このような圧接端子は、被覆電線との接続を確実にするため、電線軸方向に間隔を置いた一対の圧接板部を備え、被覆電線に対し2か所で圧接するようにしたものもある(例えば、特許文献1を参照)。   Such a press contact terminal includes a pair of press contact plate portions spaced in the axial direction of the wire in order to ensure the connection with the covered wire, and there is also one in which the press contact terminal is pressed against the covered wire at two locations. (For example, see Patent Document 1).
また、このような圧接端子100には、図9に示すように、一対の圧接板部101,101の先端縁間に跨った形状の連結片102を備え、連結片102に両圧接溝103,103間に跨る圧接刃溝104が形成されたものも知られている(例えば、特許文献2を参照)。   In addition, as shown in FIG. 9, such a pressure contact terminal 100 includes a connecting piece 102 having a shape straddling between the tip edges of the pair of pressure contact plate portions 101, 101, and the connecting piece 102 has both pressure contact grooves 103, There is also known one in which a pressure contact blade groove 104 is formed between 103 (see, for example, Patent Document 2).
このような圧接端子の場合、相手方の接続端子と接触する端子接続部106は、被覆電線に圧接端子を圧接させる際、被覆電線より受ける力により圧接板部101,101を含む圧接部分が変形する虞があることから、その変形や損傷により相手方接続端子との接触安定性が損なわれることがあるため、当該圧接部分の変形や損傷に影響されない部分に配置されていた。   In the case of such a pressure contact terminal, when the pressure contact terminal is brought into pressure contact with the covered wire, the pressure contact portion including the pressure contact plate portions 101 and 101 is deformed in the terminal connection portion 106 that comes into contact with the other connection terminal. Since there is a possibility that the contact stability with the counterpart connection terminal may be impaired due to the deformation or damage, it is arranged in a portion not affected by the deformation or damage of the pressure contact portion.
また、図9に示すような圧接端子100では、その構造上、両圧接板部101,101及び連結片部102からなる圧接部分の上方、即ち、連結片部102とは反対側に、圧接治具で押圧する押圧部105を設けることができないため、押圧部105を圧接部分とは別位置に配置していた。   Further, in the press contact terminal 100 as shown in FIG. 9, due to the structure, the press contact treatment is performed above the press contact portion composed of the two press contact plate portions 101 and 101 and the connecting piece portion 102, that is, on the opposite side to the connecting piece portion 102. Since the pressing part 105 to be pressed with a tool cannot be provided, the pressing part 105 is arranged at a position different from the press contact part.
