Abstract This invention relates to an electron tube socket which comprises a single insulation base body formed with a plurality of pin inserting through-holes positioned peripherally and spaced from each other. Terminal contacts each having a pin receiving portion are inserted into the pin inserting holes. An integral conductor portion is provided on each terminal contact and protrusions are formed in the conductor portions at the lower sides thereof. A grounding plate is positioned away from the conductor portions of said terminal contacts with a raised protrusion formed thereon. The grounding plate is positioned so that the protrusion formed on each of the terminal contacts overlies the protrusion on the grounding plate and lie along an axis which intersects or crosses the protrusion on the grounding plate when viewed in plan. In this way, an arc gap is formed between the overlying points of each terminal contact protrusion and grounding plate protrusion at the point of intersection of the longitudinal axis in plan view of the protrusions on the terminal contact and the grounding plate.
An electron tube socket comprising an insulation base body formed with a plurality of holes positioned peripherally and spaced from each other, a plurality of terminal contacts each having pin receiving portion inserted into one of said holes and having an integral conductor portion extending radially on the lower surface of said base body with a longitudinal protrusion formed along the conductor portion on the lower side thereof, a grounding plate positioned so as to be spaced from said conductor portions of said terminal contacts, and a protrusion integrally formed in said grounding plate through its entire length and positioned so that when viewed in plan the longitudinal axis of said protrusions on said conductor portions are seen to intersect the protrusion on said grounding plate at points of intersection to form arc-over gaps between said protrusions on said conductor portions and the protrusion on said grounding plate at said points of intersection.
