Abstract: A connector unit includes a first connector, a second connector and a seal member to be interposed therebetween. The first connector includes a fitting portion having a distal end portion. The second connector includes a fitted portion. A thickness of the fitting portion is reduced at the distal end portion with an inner peripheral surface of the distal end portion being recessed. The fitted portion includes an attachment portion to which the seal member is to be attached and a housing portion. When the first connector and the second connector are fitted to each other, the distal end portion is accommodated in the housing portion, and the seal member performs sealing between the fitting portion and the fitted portion by being sandwiched between the attachment portion and a portion of the fitting portion, the portion being provided further in a second direction than the distal end portion.

Abstract: A connector includes a first connector housing including a first wall. The first connector housing is attachable to a second connector housing such that the first wall opposes a second wall of the second connector housing. The first connector housing includes: a fitting chamber defined at least by the first wall, the fitting chamber allowing a counterpart connector housing to be fitted therein; and an engaging arm provided on the first wall, the engaging arm being configured to engage an engaged arm provided on the second wall of the second connector housing when the first connector housing is completely attached to the second connector housing. The engaging arm serves as an attachment state detection mechanism configured to detect an incomplete attachment state in which the first connector housing is incompletely attached to the second connector housing.
