<p>Disclosed is a CRT socket comprising a socket housing, a focus connection contact and a focus spark-gap contact, which has a snap-in terminal to connect to a high-voltage lead conductor. This snap-in terminal is composed of stationary and movable contact pieces. The socket housing has a spark electrode compartment and a socket cover. The socket cover has a hollow casing to contain the snap-in terminal of the focus spark-gap contact and a press-fit cover to close the hollow casing. The press-fit cover has a projection to enter the hollow casing and push the movable contact piece against the stationary contact piece when closing the hollow casing. This CRT socket structure permits first, checking by sight of the connection of a high-voltage lead conductor to the focus spark-gap contact, and second, easy removal of the high-voltage lead conductor from the CRT socket for maintenance or checking simply by opening the press-fit cover.</p> |
