摘要： An electron gun for cathode ray tubes which is easily assembled and reduces the cost is disclosed. The electron gun has a cathode holding structure. The cathode holding structure includes a support bracket which is fixedly fitted in the first electrode. The support bracket is provided with a plurality of insert holes spaced apart from each other. A plurality of hollow cases are received in the insert holes of the support bracket respectively and fixed to the support bracket. A cathode is concentrically received in each hollow case. The cathode holding structure also has an insulating material which is filled in the hollow case in order to hold and insulate the cathode in the hollow case. In the present invention, the gap between the cathodes and first electrode of the electron gun is easily adjusted thereby preventing the inferiority of the electron gun.
