[0054] The connector pin alignment unit (500) may be configured to include a pair of frames (510, 520) that align and fix at least one of a plurality of optical connector pins (100) and a plurality of RF connector pins (300) in the direction of the X-axis, and a pair of terminals (530, 540) that are coupled to one end and the other end of the pair of frames (510, 520).

[0055] The connector pin connection part (710) can be configured to be mechanically connected to and disconnected from the connector socket connection part (720).

At one end of the first pin body (110), a first surface (112) is formed that contacts the second surface (221a) belonging to the optical connector socket (200). The first optical cable (140) is drawn out from the other end of the first pin body (110).

[0066] The pin block (120) surrounds the first pin body (110) and serves to fasten the first pin body (110) to the connector pin alignment part (500). That is, the pin block (120) combines with the outer diameter surface of the first pin body (110) and has the function of mediating the fixation of the first pin body (110). The pin block (120) can be formed using synthetic resin.

Although the one end of the optical connector pin (100) and the one end of the optical connector socket (200) can be joined by a snap connection, the optical connector pin (100) and the optical connector socket (200) can ultimately be fixed to each other by aligning the pin block (120) by the connector pin alignment part (500) and aligning the socket block (230) by the connector socket alignment part (600), and by connecting the connector pin connection part (710) and the connector socket connection part (720) to each other.
