The terminal connection portions of the board connection terminals are respectively arranged on one side and the other side with respect to the arrangement direction surface of the plurality of board connection terminals, and the plurality of terminal insertion holes of the housing include the plurality of terminal insertion holes. It is provided in the position corresponding to the terminal connection part of the board | substrate connection terminal.

  In this connector, the terminal connection portions of adjacent board connection terminals are arranged on one side and the other side with respect to the arrangement direction surface of the plurality of board connection terminals, and the plurality of terminal insertion holes of the housing have a plurality of terminal insertion holes. Since it is provided at a position corresponding to the terminal connection portion of the board connection terminal, adjacent terminal insertion holes are not arranged along the arrangement direction surface of the plurality of board connection terminals, and adjacent terminal insertion is performed. Interference between the holes can be prevented.

  Therefore, in such a connector, since adjacent terminal insertion holes do not interfere with each other, a waterproof plug can be assembled to the terminal insertion hole without changing the size of the terminal insertion hole. Even if the portion increases, a waterproof plug can be assembled in the terminal insertion hole of the housing.

  A second aspect of the present invention is the connector according to the first aspect, wherein the terminal insertion holes adjacent to each other in the housing overlap in a direction perpendicular to an arrangement direction plane of the plurality of board connection terminals. It is characterized by being provided.
