Pluggable free-space photoelectric hybrid connector

A pluggable free-space photoelectric hybrid male connector (20), comprising:

• a second insulating substrate (21), wherein an insertion protrusion (211) is formed at a front end of the second insulating substrate (21) and a second fiber mounting hole (214) and second electrode mounting holes (213) are formed at a rear end of the second insulating substrate (21);
• and the insertion protrusion (211) is configured to match an insertion cavity (111) of a corresponding female connector (10);
• a plurality sets of metal pins (22) mounted in the second electrode mounting holes (213) respectively, wherein contact portions (221) of at least one set of the metal pins (22) are exposed from a top of the insertion protrusion (211), and contact portions (221) of at least another set of the metal pins (22) are exposed from a bottom of the insertion protrusion (211);
• a second circuit board (25) mounted at the rear end of the second insulating substrate (21) and electrically connected to the plurality of sets of the metal pins (22);
• and
• a second optical communication module, comprising:
• a second optical fiber connector (241) disposed in the second fiber mounting hole (214) and configured to carry optical fibers;
• and
• a second lens (242) disposed at a front side of the insertion protrusion (211), opposite to a light-emitting end of the second optical fiber connector (241), and configured to perform expansion processing on light beams transmitted from the male connector (20) to the female connector (10), wherein a position of the second lens (242) is arranged in such a manner that there is a distance (D) between the second lens (242) and a first lens (142) of the female connector (10) when the male connector (20) and the female connector (10) are in an insertion-connected state.
