Abstract:
1. A connection jack connectable with a connection plug having a center terminal and an earth terminal arranged on an outer peripheral side of the center terminal and arrangable in an electronic apparatus having a capacitor and a resistance for limiting inrush current disposed therein, said connection jack comprising: a housing, made of an insulating material, having an insertion opening to which the connection plug is insertable; a center electrode; and a first earth electrode and a second earth electrode each arranged on an outer peripheral side of the center electrode; wherein when the connection jack is arranged in the electronic apparatus and the connection plug is connected with the connection jack (i) the center electrode is connected to the center terminal and to the capacitor, (ii) the first earth electrode is connected to the earth terminal and to the capacitor, and (iii) the second earth electrode is connected to the earth terminal, connected in series to the resistance, and connected to the capacitor through the resistance, and wherein the first earth electrode and the second earth electrode are arranged at positions such that the earth terminal is connected to the second earth electrode before the earth terminal is connected to the first earth electrode at the time of connecting the connection plug.
