Abstract
There is disclosed a new and improved socket for making electrical connections to the pins on the neck of a cathode ray tube. The improvement includes a plurality of first conductive contacts which are arranged to engage the pins of the cathode ray tube and which include an elongated planar portion from which a cylindrical projection is integrally formed. A second conductive contact which is also planar in configuration includes a corresponding plurality of holes therein. Each of the holes has a diameter larger than the diameter of the cylindrical projections for receiving a corresponding one of the cylindrical projections. The improved socket further includes a planar insulating member positioned between the first and second conductive contacts and having a corresponding plurality of holes therein. Each of the holes of the insulating member has a diameter smaller than the corresponding hole in the second conductive contact but at least as large as the diameter of the corresponding cylindrical projections. As a result, a spark gap is formed radially from each cylindrical projection to the periphery of each hold in the second contact.
