型に折曲して形成される。 A fixed electrode 1 made of a metal plate includes a mounting portion 1a that is soldered and fixed to a printed board 2, a center conductor portion 1b in a UHF tuner, and a wide electrode portion 1c bent into an L shape from the center conductor portion 1b. The fixed electrode 1 is fixed in an upright position.
Now, the feature of the present invention lies in the movable electrode 3. The movable electrode 3 of the present invention is also constructed by providing an insulating coating 3b on a metal wire 3a, as in the conventional example. The movable electrode 3 faces the bent portion 1d of the fixed electrode 1 and extends in the direction of the center conductor 1b and the wide electrode portion 1c, that is, it is bent into an L-shape when viewed from above. There is. Then, a leg portion 3d is provided by being bent straight from the extending portion 3c, and this leg portion 3d
The tip 3a of is attached to the printed board 2 and fixed by solder. For example, the movable electrode 3 of the present invention is formed by bending the substantially central portion of an arch-shaped insulated wire into an L-shape.
