It is aimed to avoid making a movable arm portion difficult to deflect. A connector is provided with a male housing (10) connectable to a female housing (40), a sealing ring (15) to be mounted on an inner peripheral surface of the male housing (10) for sealing between the inner peripheral surface of the male housing (10) and an outer peripheral surface of the female housing (40), resiliently deformable movable arm portions (30) formed on the male housing (40), and stoppers (37) for restricting a movement of the sealing ring (15). The movable arm portion (30) includes a fulcrum portion (31) and a displacing portion (32) extending from the fulcrum portion (31) and displaceable in a direction intersecting an extending direction. The stopper (37) projects from the displacing portion (32).

Connector

A male housing () includes a housing body () with a fitting space () that accommodates tabs () of male terminal fittings (). An accommodation space () is rearward of the fitting space () and accommodates a sealing plug (). An outer peripheral portion () of the male housing () defines an outer periphery of the accommodation space (). An inner surface of the outer peripheral portion () closely contacts the sealing plug (), and plate locks () project into the fitting space (). A moving plate () to be locked by the plate locks () is arranged in the fitting space (). The male housing () includes communication spaces () between the housing body () and the outer peripheral portion () and behind the plate locks (). The communication spaces () allow communication between the fitting space () and the accommodation space ().

It is aimed to mount a sealing member into a receptacle after arranging a moving plate in the receptacle. In a fitting space () of a receptacle (), plate lock portions () are provided to project, a moving plate () to be locked by the plate locks () at a protecting position is arranged, and a sealing member () is arranged closer to an opening than the plate locks (). The receptacle () is composed of a body-side receptacle () including the plate locks () and a tip-side receptacle () arranged closer to the opening of the fitting space () than the body-side receptacle () and to be coupled to the body-side receptacle (). The sealing member () is fixed by being sandwiched between the body-side receptacle () and the tip-side receptacle ().

A lock arm () has a lock () that rides on a lock projection () while connecting two housings () and locks the lock projection () when the housings () are connected. A connection detecting member () is movable in the male housing () and between an initial position and a detection position. The connection detecting member () has a resilient detecting portion () capable of contacting the lock (). First and second restricting surfaces () are formed on a facing surface () of the lock () facing the resilient detecting portion (). The first restricting surface () restricts displacement of the resilient detecting portion () in a riding direction on the lock () with respect to the lock () and the second restricting surface () restricts displacement of the resilient detecting portion () in a direction opposite to the riding direction on the lock projection ().

A first housing includes a wide connection surface and a bearing formed on an edge on one side along the longitudinal direction of the connection surface. A second housing includes a side surface formed to face in a direction intersecting a connecting direction of the first and second housings. A lid is displaceable about a shaft supported by the bearing portion to a closed position where the lid covers the connection surface and an open position where the lid member contacts the side surface. The lid is biased from the open position to the closed position by a biasing member. An outer shape of the lid has a long side arranged along the longitudinal direction of the connection surface and a short side intersecting the long side and shorter than the long side.

It is aimed to provide a connector capable of being simplified in configuration. A connector () includes a housing () configured to be fit to hold a mating housing () by a resiliently deflectable lock arm (), and a detecting member () configured such that a movement from a standby position to a detection position is restricted in a state where the housing () and the mating housing () are not properly connected and a movement to the detection position is allowed in a properly connected state of the housing () and the mating housing (). The lock arm () includes stopper () configured to stop the detecting member () in contact therewith in the properly connected state. The housing () includes a covering wall () with which the stoppers () come into contact in a deflecting direction of the lock arm ().

A housing () includes a terminal holding portion () and a fitting space () facing the front surface of the terminal holding portion (). A retainer () is mounted in a front part of the terminal holding portion (). The retainer () is movable between a partial locking position and a full locking position. A moving plate () facing the front surface of the retainer () is accommodated in the fitting space (), and the moving plate () is formed with openings () penetrating in the front-rear direction. The retainer () is formed with operated portions () facing the openings () from behind, and a tool () inserted into the opening () can contact the operated portion ().

A moving plate () is movable in a fitting space () of a receptacle () between a protecting position and a retracted position. A sealing member () is closer to an opening than the moving plate () and closely contacts the inner surface of the receptacle (). The moving plate () has arms () including inward projecting locking projections (). A female housing () fits into the fitting space () of the receptacle () and includes a sealing surface () and recesses () on an outer surface. The sealing surface () contacts the inner surface of the sealing member () during connection to a male connector (). The recesses () are recessed on a more forward side than the sealing surface () in a fitting direction into the fitting space (), and locking projections () are locked to side surfaces of the recesses during separation from the male connector.
