Description of the Related Art Structures of Conventional Examples and Their Problems Magnetron devices in which a magnetron and its excitation circuit members are combined and integrated are widely used in microwave ovens and the like. The excitation circuit member typically includes two annular permanent magnets that are stacked on one and the other pole piece of the magnetron to magnetically couple one pole to the pole piece, and two annular permanent magnets that magnetically couple one pole to the other pole piece of the magnetron, and the other magnetic poles of both permanent magnets It consists of a frame-shaped yoke that is magnetically coupled. The frame-shaped yoke is obtained by combining a first yoke piece with a U-shaped cross section and a second yoke piece with a flat plate shape so as to have a square cross-section and tightening them with screws. The process of making several small holes and inserting and screwing bolts into these holes is complicated and is not particularly suitable for mass production.

気回路抵抗が増し、励磁効率に低下をきたす。 Therefore, a caulking method as seen in Japanese Patent Application Laid-Open No. 108961/1983 has been proposed. However, with the caulking method in which the prongs of the other joint are simply inserted into slots provided in one side of the joint pieces, and the inserted portion is crushed and deformed, the gap between the two may be caused by elongation of the protrusion during crushing or by variations in component precision. It is easy to create voids, and if there is something that creates a void here,
Not only does the mechanical strength of the frame-shaped yoke decrease, but also the magnetic circuit resistance increases, causing a decrease in excitation efficiency.

is a composite body in which a first yoke piece 6 having a U-shaped cross section and a second yoke piece 7 having a flat plate shape are combined and bonded so as to have a R-shaped cross section. However, each one of the first and second annular permanent magnets 3 and 4 is a magnetic pole, and the first
and a second magnetic pole piece, respectively, and each other magnetic pole is magnetically coupled to the frame-shaped yoke 5, respectively. Further, the electromagnetic wave emission terminal 8 of the magnetron 1 passes through the center hole of the second yoke piece 7, and the cathode terminal of the magnetron 1 passes through the first yoke piece 6 and the center hole and enters the shield case 9. It projects inside the shield case 9 and is connected to the L and C filter circuit members. 10 is the above L,

る。 By the way, the connection between the first yoke piece 6 and the second yoke piece 7 is achieved by a configuration as shown in FIGS. 2 and 3. That is, the first yoke piece 6 has a slot 13 near one side 6a.
The second yoke piece 7 has a pair of prongs 1 that protrude from one side 7a and are inserted into the slot 13.
4.15. However, 1 pair of protruding ears 1
4 and 15 are cut in a V-shape on both inner sides so that the distance between them becomes narrower toward the tip.

It is slightly larger than the plate thickness T 2 of the yoke piece 7. Further, the protruding length P of the pair of protruding ears 14 and 15 is slightly larger than the plate thickness T 1 of the first yoke piece 6.

両継鉄片６，７間に離脱不能のロツク作用が働く
のみならず、両継鉄片６，７間に相互接近の締め
つけ力が作用し、前記当接が緊密の度を増す。 As shown in FIG. 3, when the pair of prongs 14 and 15 are inserted into the slot 13 up to the base, one side 7a of the second yoke 7 comes into contact with the plate surface of the first yoke 6. In this inserted state, when a pressing force 17 for caulking is applied to the band region 16 between the slot 13 and one side 6a, the band region 16 bends and bites into the space between the pair of prongs 14 and 15. . As mentioned above, the distance between the pair of ears 14 and 15 becomes narrower toward the tip.
Not only does a non-removable locking action occur between the two yoke pieces 6, 7, but also a clamping force acts between the two yoke pieces 6, 7 as they approach each other, increasing the degree of tightness of the abutment.

片の組み合わせにより形成する形式のものにも適
用できるのは勿論である。 According to the embodiment, the first yoke 6 has a slot 13, and the second yoke 7 has a pair of prongs 1.
4 and 15, respectively, but the first yoke piece 6 may be provided with a pair of prongs, and the second yoke piece 7 may be provided with a slot. It goes without saying that the present invention can also be applied to a type in which a frame-shaped yoke is formed by a combination of three or more yoke pieces.
