A surface-mounting connector includes a repeater pin block and connector pins. The repeater pin block includes a main body consisting of a resin and having regularly arranged through holes, and a continuously extended resin spring contact portion integrally and continuously extending from the main body to be brought into contact with a surface of a printed board. The main body and the continuously extended resin spring contact portion have contact portions to be brought into contact with conductive pads of the printed board and conductive paths to be connected to the regularly arranged through holes. Each connector pin has a first pin portion on its one end. The first pin portion has a press-fit structure and is forcibly inserted in a corresponding through hole. Each connector pin also has a second pin portion on its other end. The second pin portion is used for electrical connection with an external unit. The contact portions to be brought into contact with the conductive pads arranged in a row on the same surface of the printed board are arranged on the continuously extended resin spring contact portion.

In a plug-in connector for connecting elements mounted on a backage board to other elements arranged on a back wiring board disposed perpendicular to the package board, the guide pin and the connector housing fixing screw are formed integral with each other to realize a floating connector coupling structure which is high in mounting efficiency and precision and small in size. Further, the plug-in connector can connect two different, optical and electrical connectors. Further, there is disclosed a novel optical connector plug whose radial eccentricity direction can be matched with that of a mated optical connector jack with an optical fiber aligning jig to minimize the optical fiber coupling power loss.
