Abstract: An interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together and formed by bending a first metal plate having a high modulus of elasticity. An exterior body is formed by bending a second metal plate having low electric resistance. A movable portion of the interior body includes a contact portion and elastic arms. Each of the elastic arms includes, at its tip portion, an elastically pressing portion elastically pressed against a tubular internal surface of the exterior body.

Abstract: An interior body is housed in a tubular exterior body. The interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together. Elastic arms are disposed on the movable portion so as to extend downward. Each elastic arm includes, at a lower end portion, an elastically pressing portion, which is elastically pressed against a tubular internal surface of the exterior body. Since the elastically pressing portion is elastically pressed against the exterior body, electric signals are more likely to flow between the movable portion and the exterior body and more likely to be prevented from leaking to the spring portion.

Abstract: A socket for electronic components includes a case that includes through holes of which inner wall surfaces have conductivity, and a ground contact unit that is disposed in one of the through holes and is electrically connected to an inner wall surface of the through hole. The ground contact unit includes a holding member that holds a conductive member and is fixed in the through hole. The conductive member has elasticity, and includes an intermediate portion held by the holding member, an upper extension portion extending upward from the intermediate portion, and a lower extension portion extending downward from the intermediate portion. The lower extension portion includes a ground extension portion that comes into elastic contact with the inner wall surface of the through hole, a fixed portion that is fixed to a substrate, and an impact absorbing portion that is formed between the fixed portion and the intermediate portion.

Abstract: A shield structure of a tuner apparatus includes: a circuit board on which a tuner circuit is provided; a shield case of sheet metal which accommodates and holds the circuit board; and a RF connector which is fixed to one side plate of the shield case so as to protrude outward and is electrically connected to the tuner circuit, wherein a box-shaped outer case is formed by connecting a case member of sheet metal which covers the shield case with the exception of the bottom surface portion thereof and the one side plate and a plate member of sheet metal which has a through hole, through which the RF connector passes, and covers the one side plate of the shield case, and wherein the outer case is unitized with the shield case.

Abstract: In a mounting structure of a high frequency apparatus, in an outer circumference around terminals connected to a mother board, an enclosed portion, which is brought into contact with the mother board and is enclosed by a ring-shaped convex portion provided in a cover, or an enclosed portion, which is brought into contact with the mother board and is enclosed in a ring shape by a convex portion provided in the cover and extending portions from the frame, are provided. The terminals are electrically shielded by the enclosed portion. Therefore, when a high frequency apparatus is mounted on the mother board, interfering electric waves are prevented from entering into the terminals, and thus favorable performance is obtained.

Abstract: A dual tuner is described that includes a rectangular parallelepiped casing having four side plates, partitions for dividing inside of the casing into a plurality of areas, a coaxial connector fitted to one side plate of the casing, and a circuit board mounted in the casing. Both a data tuner and a video tuner are divided by the partitions. The signal line of the data tuner which has severe spurious interference standard requirements, is set noticeably shorter than the signal line of the video tuner whose spurious interference standard requirements are not so severe.
