摘要： PROBLEM TO BE SOLVED: To provide an optical connector which hardly brings about molding strain with a cross-section shape being not horizontally long and being flat with less difference between vertical and horizontal dimensions, and can be reduced in the connector area.SOLUTION: An optical connector 31 is an optical path change type and includes a reflecting surface 36 for changing an optical path, and, for example, fitting pins 33 are provided on one surface 31a of the optical connector, through which reflected light passes, and the fitting pins are provided on opposite sides with a straight line therebetween passing a center of each optical input/output line on the one surface and are arranged symmetrically with respect to a point being the center of an optical input/output line array on the straight line. In comparison with an optical connector which has fitting pins on both sides of an optical input/output line array and has a horizontally long and flat cross-section shape, the optical connector 31 is allowed to have a smaller horizontal dimension and a larger vertical dimension and have a cross-section shape being not horizontally long and being flat with less difference between horizontal and vertical dimensions. This shape hardly brings about molding strain to be able to prevent the degradation in position accuracy of an optical fiber hole. Flexibility of optical input/output line arrangement is increased and the optical connector is miniaturized to allow high-density packaging of the optical connector.

摘要： PROBLEM TO BE SOLVED: To provide a positioning structure of an optical connector, a structure which can secure fixed positioning accuracy and which can be manufactured at low cost.
SOLUTION: As a means for mutually positioning an optical connector 1 and an optical component 2 to be connected thereto, there are formed engaging receiving grooves 11a, 11b, in one of the connecting face 1a of the optical connector 1 or the connecting face 2a of the optical component 2, and engaging projected lines 7a, 7b that fit in the engaging receiving grooves, in the other. The illustrated examples are that the optical component 2 is a circuit substrate 2 loaded with an optical element and that the optical connector 1 is a surface mounting type optical connector which converts an internal optical fiber optical path parallel with the substrate 2 toward the optical element on the substrate face 2a by means of a mirror 16a. The positioning structure by the engagement of the grooves with the projected lines, compared to a positioning structure by the engagement of circular pins with pin holes, facilitates increased accuracy in resin forming and also enables a highly accurate metallic mold to be manufactured at a low cost.
