ABSTRACT:
An improvement in an anode contact spring for use in a color cathode ray tube is disclosed. The improvement comprises positive locking means for locking an attachment end of the contact spring to a supportive member for suspending the shadow mask adjacent to the panel. The positive locking means comprises bolt means extending from the supportive member and which is located in a preselected lateral position on the member. Clasping means on the attachment end provide for clasping the supportive member. One leg of the clasping means is a hasp for engaging the bolt. An anti-twistoff fold is provided in the contact spring adjacent to the attachment end. Upon engagement by manual pressure of the clasping means with a supportive member, the clasping means expands to provide engagement of the hasp with the bolt, then contracts to provide push-click positive locking of the contact spring to the supportive member. The anti-twistoff fold allows for substantial deflection of the contact spring without twisting off and unlocking the clasping means. The preselected locating of the bolt provides for the precise lateral positioning of the anode contact spring with respect to the shadow mask and the funnel.
