信頼性に影響するという問題がある。In a magnetic field generator used for an electron tube for a beam output tube of a transmitter for a broadcast such as a television, the magnetic field generator is composed of a coil that generates a magnetic field and an electromagnet that magnetically connects both sides of the coil. Since the electron tube has a structure inserted in the coil, it is directly affected by the radiation generated by the electron tube. Conventionally, FRP is used for this type of coil bobbin material due to its mechanical strength and insulation, but the radiation resistance characteristics of FRP alone are poor, and the mechanical strength of the coil bobbin deteriorates over time, and the reliability of the coil is reduced. There is a problem that it affects sex.

い様にしたコイルボビンを構成するものである。The coil bobbin according to the present invention is a coil bobbin in which a radiation shielding material made of a thin plate made of lead and a resin interlayer insulating material having high strength are laminated and wound in layers and formed into a cylindrical shape so that radiation resistance characteristics and a coil can be easily formed. It is what constitutes.
以下、本考案の実施例につき図面を用い説明する。 Embodiments of the present invention will be described below with reference to the drawings.

めに鉛の薄板を主としてコイルボビンの外径側に巻付け
て用いるのが一般的である。The coil bobbin for magnetic field generation used in the electron tube of the conventional structure is wound with a wide and long FRP (epoxy resin containing glass fiber) and molded into a cylindrical shape. After molding, a lead thin plate is mainly used to block radiation. It is generally used by winding it around the outer diameter side of the coil bobbin.

は旋盤等で表面を切削加工を行なうが、鉛の薄板が充分
に固定されていないため作業性が悪くなっている。In this method, since the lead thin plate is wound after forming the coil bobbin, unevenness is generated on the inner and outer diameters of the coil bobbin and the end surface, which lowers workability during coil winding and removes unevenness on the coil bobbin surface. The surface is cut with a milling machine or a lathe, but the workability is poor because the thin lead plate is not sufficiently fixed.

After winding P3 together to form the coil bobbin 1, the end face and the coil winding portion are cut by a milling machine or a lathe to flatten the unevenness.
