Further, the inside of the extended portion 17 is communicated with the bolt support hole 15.

この延設部１７は、第１ハウジング５と第２ハウジング９とが嵌合した状態で、第１ハウジング５のボルト締結部１３の外周を覆うように、ボルト締結部１３の外周側に配置される。   The extending portion 17 is disposed on the outer peripheral side of the bolt fastening portion 13 so as to cover the outer periphery of the bolt fastening portion 13 of the first housing 5 in a state where the first housing 5 and the second housing 9 are fitted. The

このように構成されたコネクタ１において、第１ハウジング５の被嵌合部３と第２ハウジング９の嵌合部７との間、ボルト１１が挿入される空間側と被嵌合部３の内部空間側との間、第１ハウジング５と筐体２３との間には、隙間が形成されており、コネクタ１の外部から内部に向けて水などが侵入する恐れがある。   In the connector 1 configured as described above, the space side between the fitting portion 3 of the first housing 5 and the fitting portion 7 of the second housing 9 and the space side into which the bolt 11 is inserted and the inside of the fitting portion 3. A gap is formed between the space side and between the first housing 5 and the housing 23, and water or the like may enter from the outside of the connector 1 toward the inside.

そこで、コネクタ１には、各隙間から水などが侵入することを防止するために、第１防水部材１９と、第２防水部材２１と、第３防水部材２９とが設けられている。   Therefore, the connector 1 is provided with a first waterproof member 19, a second waterproof member 21, and a third waterproof member 29 in order to prevent water and the like from entering from each gap.

第１防水部材１９は、第１ハウジング５の被嵌合部３と第２ハウジング９の嵌合部７との間に配置され、合成ゴムなどの弾性材料からなり、被嵌合部３の内周面と嵌合部７の外周面とに密着している。   The first waterproof member 19 is disposed between the fitted portion 3 of the first housing 5 and the fitted portion 7 of the second housing 9 and is made of an elastic material such as synthetic rubber. It is in close contact with the peripheral surface and the outer peripheral surface of the fitting portion 7.

この第１防水部材１９は、図９の矢印で示すように、第２ハウジング９側から第１ハウジング５の被嵌合部３内に侵入しようとする水などの侵入を防止する。このような第１防水部材１９により、被嵌合部３と嵌合部７との間をシールすることができる。   As shown by the arrow in FIG. 9, the first waterproof member 19 prevents intrusion of water or the like that is about to enter the fitted portion 3 of the first housing 5 from the second housing 9 side. Such a first waterproof member 19 can seal between the fitted part 3 and the fitting part 7.

第２防水部材２１は、第１ハウジング５の挿入孔５１と第２ハウジング９の延設部１７との間に配置され、合成ゴムなどの弾性材料からなり、挿入孔５１の内周面と延設部１７の外周面とに密着している。   The second waterproof member 21 is disposed between the insertion hole 51 of the first housing 5 and the extending portion 17 of the second housing 9 and is made of an elastic material such as synthetic rubber, and extends from the inner peripheral surface of the insertion hole 51. It is in close contact with the outer peripheral surface of the installation portion 17.

この第２防水部材２１は、図９の矢印で示すように、ボルト支持穴１５に沿ってボルト締結部１３に侵入し、挿入孔５１から被嵌合部３内に侵入しようとする水などの侵入を防止する。このような第２防水部材２１により、ボルト支持穴１５及びボルト締結部１３と被嵌合部３との間をシールすることができる。   As shown by the arrow in FIG. 9, the second waterproof member 21 enters the bolt fastening portion 13 along the bolt support hole 15, such as water that tries to enter the fitting portion 3 from the insertion hole 51. Prevent intrusion. Such a second waterproof member 21 can seal between the bolt support hole 15 and the bolt fastening portion 13 and the fitted portion 3.

ここで、従来では、第２防水部材２１と同様のシール機能を有する防水部材が、ボルト１１とボルト支持穴１５との間に配置されていた。このため、ボルト１１の挿入や締結によるボルト１１との摺動によって、防水部材に損傷が生じ、防水部材のシール性が低下する恐れがあった。   Here, conventionally, a waterproof member having a sealing function similar to that of the second waterproof member 21 is disposed between the bolt 11 and the bolt support hole 15. For this reason, the waterproof member is damaged due to the insertion of the bolt 11 or sliding with the bolt 11 by fastening, and the sealing performance of the waterproof member may be deteriorated.

これに対して第２防水部材２１は、ボルト１１の挿入や締結となんら干渉しない位置に配置されているので、ボルト１１と第２防水部材２１とが摺動することがなく、第２防水部材２１に損傷が生じることがなく、第２防水部材２１のシール性が低下することがない。   On the other hand, since the second waterproof member 21 is disposed at a position where it does not interfere with the insertion or fastening of the bolt 11, the second waterproof member 21 does not slide between the bolt 11 and the second waterproof member 21. 21 is not damaged, and the sealing performance of the second waterproof member 21 is not lowered.

第３防水部材２９は、第１ハウジング５と筐体２３の孔部２７との間に配置され、合成ゴムなどの弾性材料からなり、第１ハウジング５の外周面と孔部２７の内周面とに密着している。   The third waterproof member 29 is disposed between the first housing 5 and the hole 27 of the housing 23 and is made of an elastic material such as synthetic rubber, and the outer peripheral surface of the first housing 5 and the inner peripheral surface of the hole 27. It is in close contact with.

この第３防水部材２９は、第１ハウジング５の外周面から筐体２３内に侵入しようとする水などの侵入を防止する。このような第３防水部材２９により、第１ハウジング５と筐体２３との間をシールすることができる。   The third waterproof member 29 prevents water or the like from entering the housing 23 from the outer peripheral surface of the first housing 5. Such a third waterproof member 29 can seal between the first housing 5 and the housing 23.

このようなコネクタ１では、被嵌合部３と嵌合部７との間に、被嵌合部３と嵌合部７とに密着し、被嵌合部３の内部と外部とを区画する第１防水部材１９が設けられているので、第１防水部材１９によって水などが被嵌合部３の外部から内部に侵入することを防止することができる。   In such a connector 1, the fitted portion 3 and the fitted portion 7 are closely attached between the fitted portion 3 and the fitted portion 7, and the inside and the outside of the fitted portion 3 are partitioned. Since the first waterproof member 19 is provided, the first waterproof member 19 can prevent water or the like from entering the inside of the fitted portion 3 from the outside.

また、被嵌合部３と延設部１７との間には、被嵌合部３と延設部１７とに密着し、被嵌合部３の内部と延設部１７の内部とを区画する第２防水部材２１が設けられているので、ボルト１１とボルト支持穴１５との間に防水部材を設けなくとも、第２防水部材２１によってボルト支持穴１５から侵入した水などが被嵌合部３の内部に侵入することを防止することができる。   Moreover, between the to-be-fitted part 3 and the extension part 17, it closely_contact | adheres to the to-be-fitted part 3 and the extension part 17, and the inside of the to-be-fitted part 3 and the inside of the extension part 17 are divided. Since the second waterproof member 21 is provided, water or the like that has entered from the bolt support hole 15 by the second waterproof member 21 is fitted without the waterproof member provided between the bolt 11 and the bolt support hole 15. Intrusion into the inside of the part 3 can be prevented.

従って、このようなコネクタ１では、第１ハウジング５と第２ハウジング９との嵌合状態をボルト１１で保持する際に、第２防水部材２１とボルト１１とが摺動することがなく、防水部材とボルト１１との摺動による防水部材の損傷を防止でき、シール性を確保することができる。   Therefore, in such a connector 1, when the fitting state between the first housing 5 and the second housing 9 is held by the bolt 11, the second waterproof member 21 and the bolt 11 do not slide and are waterproof. The waterproof member can be prevented from being damaged by sliding between the member and the bolt 11, and the sealing performance can be secured.

また、第１ハウジング５と筐体２３の孔部２７との間には、第１ハウジング５と孔部２７とに密着し、筐体２３の内部と外部とを区画する第３防水部材２９が設けられているので、第３防水部材２９によって水などが筐体２３の外部から内部に侵入することを防止することができる。   Further, a third waterproof member 29 that is in close contact with the first housing 5 and the hole 27 and separates the inside and the outside of the housing 23 between the first housing 5 and the hole 27 of the housing 23. Since the third waterproof member 29 is provided, water or the like can be prevented from entering the inside of the housing 23 from the outside.

なお、本発明の実施の形態に係るコネクタでは、第１ハウジングとボルト締結部とが別体で形成されているが、これに限らず、第１ハウジングとボルト締結部とを連続する一部材として一体に形成してもよい。   In the connector according to the embodiment of the present invention, the first housing and the bolt fastening portion are formed separately. However, the present invention is not limited thereto, and the first housing and the bolt fastening portion are continuous as one member. You may form integrally.

このような場合にも、被嵌合部と延設部との間に第２防水部材を設けることにより、ボルト支持穴からボルト締結部に侵入した水などが被嵌合部内に侵入することを防止することができる。   Even in such a case, by providing the second waterproof member between the fitted portion and the extending portion, water or the like that has entered the bolt fastening portion from the bolt support hole can enter the fitted portion. Can be prevented.
