Connector assembly

A connector assembly comprising a first connector and a second connector, wherein:

• the second connector is mateable with the first connector along a front-rear direction under a state where the first connector is located forward of the second connector in the front-rear direction;
• the first connector comprises a first inner structure and a first outer member;
• the first inner structure comprises a first connector body;
• the first outer member is attached to the first inner structure;
• the first outer member has a first lock surface, a first regulation portion and a first abutment portion;
• the first lock surface faces forward;
• the first regulation portion faces rearward;
• the first abutment portion faces rearward;
• the second connector comprises a second inner structure and a second outer member;
• the second inner structure comprises a second connector body and a second abutment portion;
• the second connector body is connected to the first connector body under a mated state where the first connector and the second connector are mated with each other;
• the second abutment portion faces forward;
• the second abutment portion is brought into abutment with the first abutment portion when the second connector is mated with the first connector;
• the second outer member is attached to the second inner structure;
• the second outer member has a second lock surface and a second regulation portion;
• the second lock surface faces rearward;
• under the mated state, the second lock surface faces the first lock surface in the front-rear direction and regulates a rearward movement of the second connector relative to the first connector;
• the second regulation portion faces forward;
• under the mated state, the second regulation portion faces the first regulation portion in the front-rear direction and regulates a forward movement of the second connector relative to the first connector;
• the first regulation portion and the first lock surface are apart from each other by a first distance in the front-rear direction;
• the second regulation portion and the second lock surface are apart from each other by a second distance in the front-rear direction;
• when the first regulation portion is located forward of the first lock surface, the first distance is longer than the second distance;
• when the first regulation portion is located rearward of the first lock surface, the first distance is shorter than the second distance;
• and
• under the mated state, the second outer member is movable relative to the first outer member along the front-rear direction.
