Abstract:
1. A connector that is to be coupled with a board which includes a top surface and a bottom surface, which is formed with an opening penetrating from the top surface to the bottom surface, which is provided with a contact point close to the opening, and in which a device receiving electric power via the contact point is mounted on at least the top surface, in a state in which the connector is inserted from a side of the top surface of the board and protrudes from the both of the top surface and the bottom surface, the connector comprising: a housing that includes a leg section and a head section, the leg section including a side surface which faces an edge of the opening when being inserted in the opening and is inserted in the opening to protrude on a side of the bottom surface of the board, the head section being positioned on the side of the top surface of the board in a state in which the leg section is inserted in the opening and including a size spreading up to a position facing the contact point with respect to a direction along the top surface of the board; a retainer piece that includes one end which is fixed to a portion of the leg section which portion protrudes on the side of the bottom surface of the board in the state of being inserted in the opening, and a cantilever spring section which extends toward the bottom surface of the board while obliquely separating from the side surface, and which is pressed by the edge of the opening to be deformed in a direction approaching the side surface when the leg section is inserted in the opening, and an apex section of which goes through the opening to the side of the bottom surface of the board to recover from being deformed so as to prevent the board from being pulled out; and a contact that has a shape protruding from the head section toward the top surface of the board, and that is pressed by the contact point of the top surface of the board to be elastically deformed when the leg section is inserted in the opening so as to press the contact in a state of being retained by the retainer piece, and that serves for supplying electric power to the contact point; wherein the retainer piece includes a curved section that continues from the cantilever spring section and is curved toward the side surface from a tip of the cantilever spring section which tip extends toward the bottom surface of the board; and an interior section that is curved toward the head section from a tip of the curved section which tip is on a side approaching the leg section, and that is arranged inside the opening to spread along the edge of the opening in the state in which the connector is coupled with the board.
