To provide an airtightness inspection device capable of easily performing airtightness inspection for checking a waterproof performance of a shunt connector plug.SOLUTION: An airtightness inspection device for shunt connector plugs, includes a nipple 16 with a built-in coupler 15 attached to an airtight jig body 11, and an inspection space 12. The airtightness inspection device 10 is fitted to a shunt connector plug 20, and a seal 22 of the shunt connector plug is firmly depressed to close an air escape route. A test gauge is inserted into a coupler 15, and air is sent therefrom by a pump so as to form a state where air is sealed in the inspection space 12. It is confirmed that a reference-value pressure does not drop within a prescribed time after that. When doing them, the airtightness of the shunt connector plug 20 can be easily inspected, with it connected to the cable 25.SELECTED DRAWING: Figure 5

    【課題】転てつ機コネクタプラグの耐水性能を確認する気密検査を、容易に行うことができる気密検査装置を提供する。【解決手段】本発明における転てつ機コネクタプラグの気密検査装置は、気密治具本体11にカプラ15が組み込まれているニップル16が取り付けてあり、検査空間12を備えている。気密検査装置10を転てつ機コネクタプラグ20と嵌合し、転てつ機コネクタプラグのシール22をしっかりと押圧し空気の逃げ道を塞ぐ。そしてカプラ15に試験ゲージを差し込みそこからポンプによって空気を送り、検査空間12で空気が密閉された状態をつくる。その後一定時間で基準値の圧力が下がらないことを確認する。これらを行うとき、転てつ機コネクタプラグ20はケーブル25が結線された状態で容易に気密検査できる。【選択図】図5
