It is aimed to provide a connector capable of dispersing stress during unlocking and avoiding enlargement in a connected state. A connector includes a housing body and a lock arm for locking a mating housing in a connected state. The lock arm includes a leg rising from the housing body and an arm body facing the housing body and extending to intersect the leg. The leg is inclined in a connecting direction of the mating housing with distance from the housing body. The lock arm includes an entrance space, into which a tip of the mating housing enters, in a formation range of the leg in the connecting direction and between the leg and the arm body.

It is aimed to provide a connector capable of ensuring lock reliability. A connector includes a detector allowed to move from a standby position to a detection position after both housings are connected. The detector includes a locking piece to be locked to a lock arm at the standby position before the housings are connected. The lock arm of the housing includes a releasing portion to be pressed at the time of separating the housings, a stopper contactable by the detector having reached the detection position at a position facing the releasing portion, two links linking the releasing portion and the stopper and facing each other, and an insertion hole formed inside the releasing portion, the stopper and the links, the locking piece being inserted into the insertion hole.

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 ().

Connector with receptacle having moving plate and sealing member mounted in the 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 ().

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 ().
