Surface Mount Connector

A surface mount connector comprising:

• a box-shaped electrically insulating substrate side housing with an opening on one side, the substrate side housing including a rectangular terminal mount wall, and four side walls standing from respective four sides of the terminal mount wall;
• a plurality of electrically conductive terminals provided on the terminal mount wall;
• and
• a plug connector including a plug housing configured to be detachably inserted into the substrate housing,
• wherein the substrate side housing is capable of being mounted on a printed board 100 such that the surface mount connector is used either in a straight mounting form in which the opening opens upwards from the printed board, or in a right-angle mounting form in which the opening opens sideways with respect to the printed board,
• wherein the terminal mount wall is a wall extending in a plane defined by mutually orthogonal X and Y axes,
• wherein the terminals are arranged in two rows, the rows being apart from each other in an X axis direction, such that the terminals in each row we in alignment with one another in a Y axis direction,
• wherein the four side walls of the substrate side housing consist of two first side walls which are separated from each other in the X axis direction, and two second side walls which are separated from each other in the Y axis direction,
• wherein a lock part is provided on one of the two first side walls for detachably locking the plug housing in an inserted position,
• wherein, on each of the second side walls, a first reinforcement plate mount part and a second reinforcement plate mount part are provided at two different positions apart from each other in the X axis direction, and a reinforcement plate is allowed to each of the two first and the two second reinforcement plate mount parts, and
• wherein the reinforcement plates mounted to the two first reinforcement plate mount parts and/or the two second reinforcement plate mount parts have respective outer edges which abut and are fixed to the printed board.
