Board end connector and connector assembly

A connector assembly, comprising:

• a board end connector, comprising:
• a board end connector body;
• and
• a board end housing comprising a board end accommodating part and a buckling slot;
• wherein the board end accommodating part accommodates the board end connector body;
• an end surface of the board end accommodating part in the first direction comprises a board end opening;
• wherein the buckling slot is disposed at one side of the board end accommodating part;
• a buckling bump is provided in the buckling slot;
• a sidewall of the buckling bump in a second direction orthogonal to the first direction and away from the board end accommodating part comprises a board end buckling part;
• the board end buckling part comprises a retaining opening and a buckling elastic piece;
• one end of the buckling elastic piece is connected with a side edge of the retaining opening in the first direction and close to the board end accommodating part;
• the other end of the buckling elastic piece extends in a direction away from the board end accommodating part;
• the other end of the buckling elastic piece is inclined to a sidewall of the corresponding buckling slot in the second direction and away from the board end accommodating part;
• the other end of the buckling elastic piece is bent into the buckling slot;
• and
• a wire end connector comprising a wire end connector body, a wire end housing accommodating the wire end connector body, and an unlocking member, the wire end housing comprising two buckling bumps, the outer surfaces of the two buckling bumps in the second direction respectively comprising a buckling recess, the unlocking member being disposed at one side of the wire end housing, the unlocking member comprising two unlocking arms respectively disposed in the two buckling bumps, the outer side edges of the two unlocking arms in the second direction respectively comprising a wire end buckling part and an unlocking part, the wire end buckling part corresponding to the buckling recess;
• wherein when the wire end connector is connected to the board end connector;
• the two buckling bumps would be respectively disposed in the buckling slot;
• the buckling elastic piece of the board end buckling part would be disposed in the buckling recess and corresponds to the wire end buckling part;
• when the unlocking member moves in a direction away from the board end connector, the unlocking part would pass through the buckling recess and pushes the buckling elastic piece.
