A CRT socket has a partition wall for partitioning a focus contact storing chamber and a base insertion hole which has sufficient strength, while maintaining a creepage distance between a focus contact and a signal contact sufficient to avoid arcing. The focus contact is formed in a leaf shape. A partition wall on a side of the base portion is interposed utilizing a gap in which a pin-type focus contact is interposed between a base and a focus pin in a cathode ray tube. The outside face of a projecting portion is covered with the partition wall. Increased strength is obtained in the partition wall for partitioning the focus contact storing chamber and the base insertion hole. The creepage distance between the focus contact and the signal contact is lengthened by forcing charges to travel, not only over the surfaces, but also along overlapping surfaces.
