Abstract
A connector structure comprising an electrically conductive plate having a plurality of through holes formed therein, an electrically insulated film formed on the inner wall of at least one of the through holes, an electrically conductive film formed on the inner wall of at least one other through hole, and an electrically conductive material of a low melting point provided within the through holes. The low melting point material provided in the through holes whose inner walls are coated with an electrically insulating film is insulated from the electrically conductive plate and such through holes may serve to receive signal propagating pins. The low melting point material in the through holes whose inner walls are coated with an electrically conductive film are tightly bonded to its inner wall due to the wettability between the low melting point material and the electrically conductive film so that such through holes may serve to receive a common potential pin to electrically stabilize the electrically conductive plate and to reduce electrical capacitance unnecessarily formed between the signal propagating pin receiving through holes. Thus, the connector structure is adapted for a high speed signal transmission without suffering substantial crosstalk noise.
