Patent ID: 11749943

Abstract:
It is aimed to provide a connector mating body capable of preventing a sealing member from damage when a bolt is tightened and loosened. A connector mating body (1) is formed by tightening a bolt (4) arranged in a collar (6) of a first housing (2) with a nut (5) of a second housing (3). A reduced-diameter portion (44) having a smaller outer diameter than a flange portion (43) of a head portion (41) is formed on a part of a tip side (L2) of the head portion (41) of the bolt (4). A tip surface (441) of the reduced-diameter portion (44) is in contact with a base end surface (611) of the collar (6). A tip part (462) of a first oil-proof sealing member (46) is sandwiched between the base end surface (611) of the collar (6) and a tip surface (431) of the flange portion (43).
