Description

  The present invention is an electric wire connection connector mainly used for collecting ground wires such as ground wires. More specifically, the present invention inserts the required number of terminals connected to the tip of the ground wire in parallel to electrically connect the wires. In particular, the present invention relates to a wire connecting connector that can be securely connected.

  Conventionally, as an electric wire connection connector for electrically connecting electric wires to each other, the electric wires connected to each other are electrically connected by inserting multiple electric wires into the connector in parallel. Many proposals have been made (see, for example, Patent Document 1 below).

  On the other hand, a current-carrying terminal metal fitting is connected in advance to the tip of the electric wire, and a plurality of electric cables connected to the terminal metal fitting are inserted into the housing of the connector, and a plurality of electric wires are connected via the conductive plate in the housing. A cable in which cables are electrically connected has been proposed and well known (for example, see Patent Document 2 below).

  Some of these electric wire connection connectors are for connecting two wires, connecting only two wires, for connecting three wires, for connecting four wires, and more. All of these wire connection connectors are designed to contact the current-carrying metal fittings inserted into the connector directly between the cables or via terminal fittings attached to the ends of the cables. .
