And abut the tip surface 10a of the first peripheral wall 10 on the same surface.
- the protruding wall 14 of the fitting portion 9 of one connector 33 is fitted into the cutout portion 16 of the other connector 4, and the flange portion 8 is fitted into the second peripheral wall 11, The rattling of the connector 4 with the housing 20 is prevented. Thereby, the undesirable deformation
- the exposed conductor 22 of the flat circuit body 2 comes into elastic contact with the terminal 27 in the terminal accommodating chamber 18 that communicates with the connector fitting chamber 5.
- FIG. 15 shows a state in which one connector 33 ′ in the example of FIG. 11 is fitted to the other connector 4 as in the example of FIG. 14.
- the rising wall portion (protruding wall) 24 of the protruding wall 23 of one connector 33 ′ is fitted into the notch portion 16 of the other connector 4 in the same manner as the protruding wall 14 in the example of FIG.
- the upper and lower wall portions 10 c of the first peripheral wall 10 are fitted in the groove portion 26 between the protruding plate portion 25 and the block portion 7.
- the terminal 27 is provided on the other connector 4, but instead of the terminal 27, a flat circuit body (2) as in the one connector 3 is provided, and the terminal of the flat circuit body (2) is provided. It is also possible to connect and provide a terminal (not shown) having an elastic contact portion (27a) to the conductor (22).
- the flat circuit connector according to the present invention can prevent rattling between connectors when an external force is applied to the flat circuit body.

Abstract
Description
(1) フラット回路体の端末部に樹脂成型された一方のコネクタと、前記端末部の導体に接続する端子を有し前記一方のコネクタと嵌合する他方のコネクタとを備え、前記一方のコネクタが、樹脂製のブロック部と、前記ブロック部の嵌合方向後側に一体形成された前記ブロック部よりも大径な鍔部とを有し、前記鍔部の前記フラット回路体の主面と平行な面には突壁が設けられ、前記他方のコネクタが、前記ブロック部と嵌合する第1の周壁と、前記第1の周壁の前記嵌合方向後側に一体形成されて前記鍔部と嵌合する第2の周壁とを有し、前記第2の周壁には前記突壁と嵌合する切欠部が形成されたフラット回路用コネクタ。
これに対して、上記(4)記載の構成によれば、上記(1)又は(2)に記載の構成でコネクタ相互のガタつきを防止することで、シール部材の好ましくない変形を防いで、コネクタの防水性を良好に維持させることができる。また、シール部材自体の弾性力で両コネクタ間のガタつきを防いで、防水性を一層高めることができる。
この結果、フラット回路体に外力が作用した場合等においてもコネクタ相互のガタつきを防止することができ、これに加えて、フラット回路体に外力が作用した場合等においても防水シール性を良好に維持することのできるフラット回路用コネクタを提供できる。
この結果、フラット回路体に外力が作用した場合等においてもコネクタ相互のガタつきを防止することができ、これに加えて、フラット回路体に外力が作用した場合等においても防水シール性を良好に維持することのできるフラット回路用コネクタを提供できる。
なお、本実施形態では、鍔部8の上下面に一対の突壁14が形成され、第2の周壁11には当該一対の突壁14と嵌合する一対の切欠部16が形成される構成としたが、鍔部8の上下面の少なくとも一方に突壁14が形成され、第2の周壁11には当該突壁14と嵌合する切欠部16が当該突壁14に対応した位置に形成され、突壁14に切欠部16が嵌合する構成としてもよい。
