 本明細書に記載された技術は、コネクタに関する。 The technology described in this specification relates to a connector.
 従来、回路基板の導電路にコネクタの端子が接続される技術が知られている。特許文献1の電気接続箱は、直線状に延びた複数本の接続端子を挿入可能な複数の貫通孔が並んで形成された第1台座と第2台座とを備え、第1台座及び第2台座の各貫通孔に複数本の接続端子が挿入された状態で第1台座と第2台座とが結合され、接続端子の下端部がプリント回路基板の端子孔に挿入されて半田付けされている。 Conventionally, a technique for connecting a connector terminal to a conductive path of a circuit board is known.

 ところで、電気接続箱内の回路を1枚の回路基板で形成するよりも複数枚の回路基板で回路を形成した方が電気接続箱内の空間を有効に利用することができ、配線密度を高めることが可能になると考えられる。しかしながら、特許文献1の構成では、複数の接続端子が直線状に延びる形状であるため、複数枚のプリント回路基板を接続できず、空間内の配線密度を高めることが容易ではないという問題がある。 By the way, the space in the electrical connection box can be used more effectively and the wiring density can be increased by forming the circuit with a plurality of circuit boards than when the circuit in the electrical connection box is formed with a single circuit board. It will be possible. However, in the configuration of Patent Document 1, since the plurality of connection terminals have a shape extending linearly, a plurality of printed circuit boards cannot be connected, and it is not easy to increase the wiring density in the space. .

 本構成によれば、第1台座部と第2台座部とが積み重ねられた状態では、ハウジングの後方側で第1貫通孔の軸方向とは異なる方向に延びる第1接続端子に第1回路基板を接続することが可能になるとともに、ハウジングの後方側で第2貫通孔の軸方向及び第1接続端子とは異なる方向に延びる第2接続端子に、第1回路基板とは異なる第2回路基板を接続することが可能になる。これにより、コネクタの接続端子に複数枚の回路基板を接続することができるため、空間内の配線密度を高めることが可能になる。
 また、複数段の接続端子を異なる台座部が別々に保持することで、第1接続端子を第1台座部に固定する工程と、第2接続端子が第2台座部に固定する工程とを別工程で行うことができるため、金型、成形、端子曲げ加工の制限を受けないで製造することが容易になり、コネクタの多段化や1つのコネクタで複数の回路基板に接続する等、構造の自由度を高めることができる。
