Abstract

An electron gun assembly for use in a color CRT includes a pair of insulating support rods, three inline indirectly heated cathode disposed between the support rods, a heater for each of the cathodes and a pair of improved, reinforced heater tabs. The heater includes a pair of heater legs which are attached to the heater tabs. Heater bead straps are provided for attaching the heater tabs to the support rods. The electron gun also includes a plurality of electrodes for focusing and accelerating an electron beam generated by the cathodes. The reinforced heater tabs comprise a main body portion including a first and a second part. Each of the parts is attached to one of the heater legs. Each of the heater tabs has a pair of outwardly directed feet each of which is connected to one of the parts of the main body portion by a pair of substantially orthogonal legs extending therebetween. The reinforced heater tabs include a first reinforcing structure extending between the parts of the main body portion and the legs and a second reinforcing structure extending between the legs and the feet to maintain the rigidity of the heater tabs. The first reinforcing structure also provides locating means for a conformal heater tab associated with the center cathode of the electron gun.
