摘要： A CATV system comprises two coaxial cables (11, 12) for transmitting information obtained from a center unit, a slide switch (1), and a CATV converter (30). As a slider (73) of the slide switch is slided in one direction with the same in contact with a common contact (101) connected to the CATV converter, the slider is placed in contact with a first fixed contact (104) connected to one coaxial cable while a first terminating contact (110) connected to a first terminating resistor (13) is separated from the first fixed contact. When the slider is slided in the other direction, the slider is placed in contact with a second fixed contact (107) connected to the other coaxial cable, while a second terminating contact (111) connected to the second terminating resistor (14) is separated from the second fixed contact. Accordingly, each of the coaxial cables is not opened through selection of the slide switch, whereby mixing of an image is prevented from occurring due to mismatching.

摘要： A coaxial cable is electrically connected to a connector receptacle by means of a coaxial cable connector plug. The coaxial cable connector plug comprises a clip which acts as an elastic pressure contact connected to a central conductor of the coaxial cable, and a plug pin electrically connected to the clip and adapted to be inserted into a receptacle opening of the connector receptacle. The clip and the plug pin are integrally formed in a single metallic plate. The clip is formed by folding the metallic plate at one end portion, while the plug pin is formed at the other end portion of the metallic plate by curling the same, with engaging portions being formed at the joint portion of the clip and the plug pin and protruding in the direction orthogonal to the longitudinal direction. The clip is housed in an insulating inner casing, while the pin is guided outward extending therefrom. The inner casing is covered with a shield casing. The inner casing is formed with an aperture for insertion of a center conductor of a coaxial cable at the position corresponding to the clip and the shield casing is formed with an aperture for insertion of an inner insulation of the coaxial cable at the corresponding portion. An outer conductor of the coaxial cable is pressure fixed to the side surface of the shield casing.

摘要： A fixing structure is disclosed for fixing an intermediate frequency transformer or other electronic component to a flexible and deformable base plate. The component comprises a base portion for fixing it to the base plate and the base plate is formed with an aperture for receiving the base portion. The base plate includes a strip portion extending along a portion of the periphery of the aperture. The component is provided with a protrusion which extends laterally from the base portion thereof. The protrusion is so formed and so located on the base portion of the component that when the base portion is inserted into the aperture, the protrusion engages the strip portion and deforms it in a direction perpendicular to the surface of the base plate, so that the diameter of the aperture shrinks, whereby the base portion is strongly gripped by at least a portion of the periphery of the aperture.

摘要： A housing for an electronic tuner or the like comprises: a shield frame defining a space to house circuitry, and an auxiliary base plate enclosing one side of the space left open by the frame and preferably serving to shield the circuitry in cooperation with the shield frame. A novel structure is disclosed for mechanically securing the auxiliary base plate to the shield frame simply and in such a manner that the auxiliary base plate can be easily removed if necessary. The frame and the auxiliary base plate engage each other elastically and resiliently by means of tongues, apertures and/or notches. No special step of either soldering or bending the auxiliary base plate or shield frame with pliers, etc., is required to maintain the parts in position. One or more shield plates may be supported by the auxiliary base plate and the shield frame and divide the space into sections.
