[0061] Figures 1A-1D is a schematic diagram showing a series unit according to the present invention. Figure 1A is its rear view, Figure 1B is its front view, Figure 1C is its side view, Figure 1D is its top view. It should be noted that in the following description, unless otherwise specified, the directions mentioned are based on Figure 1B status shown. The side facing the extension direction of the TV terminal 6 is called the front side or the front side. Figure 1A and Figure 1B middle left to right direction and Figure 1D The up and down direction in is called the horizontal direction. Figure 1C and Figure 1D The left-to-right direction in is called the front-back direction. Figure 1A , Figure 1B and Figure 1C The up and down directions in are referred to as up and down directions as shown in the drawings.

[0062] like Figures 1A-1D As shown, the series unit 1 includes a unit case 3 , an input terminal 5 , an output terminal 8 , a TV ...

[0118] The second embodiment of the present invention is described below.

[0119] Figures 6A-6D is a schematic diagram showing a series unit 1A according to the present embodiment; Figure 6A is its rear view, Figure 6B is its front view, Figure 6C is its side view, Figure 6D is its top view.

[0120] Since the structure of the series unit 1A is only partially different from that of the series unit 1, the differences will be mainly described below.

[0121] like Figures 6A-6D As shown, the series unit 1A comprises a unit housing 3 consisting only of a first housing part 3a without a second housing part 3b.

[0122] The input 5 is rotatably supported on the rear surface of the unit case 3 in the same manner as the output 8 , and the input 5 is placed with its rotational surface parallel to the rear surface of the unit case 3 .

[0123] In the series unit 1A configured as described above, only the rotational direction of the input end 5 is different from the series ...

[0126] A third embodiment according to the present invention is described below.

[0127] Figures 7A-7D is a schematic diagram showing a series unit 1B according to the present embodiment; Figure 7A is its rear view, Figure 7B is its front view, Figure 7C is its side view, Figure 7D is its top view.

[0128] Since the structure of the series unit 1B is only partially different from that of the series unit 1, the differences will be mainly described below.

[0129] like Figures 7A-7D As shown, except that the series unit 1B includes a two-pronged (two-pronged) terminal 95 instead of the input terminal 5, the configuration method of the series unit 1B is the same as that of the series unit 1, wherein the two-pronged terminal 95 has a connection to the F- The two connection parts (connection / disconnection end parts) 15 of the outer conductor of the plug-like pin and its outer shape is T-shape.

[0130] One of the bifurcated terminals 95 is used as an input, and the o...

Abstract

A series unit comprises an input terminal and an output terminal each composed of a tubular receptacle having a center conductor and an external conductor provided concentrically with the center conductor, a television terminal, and a unit case for supporting the input terminal, the output terminal, and the television terminal. The external conductors of the terminals are electrically interconnected through the unit case. The center conductors are electrically interconnected in the space defined inside the unit case. The orientation of the connection end of the unit case is perpendicular to the connection / disconnection end to / from which the terminal of the cable is connected / disconnected. The input terminal and the output terminal are constituted as movable terminals rotatable at the connection ends of the unit case. The planes defined by the center axes of the connection / disconnection ends by the rotation of the movable terminals are perpendicular to each other.

Description

technical field [0001] The invention relates to series units for use in television receiving systems. In particular, the present invention relates to the structure of series-connected units having a good effect in updating the current series-connected unit. Background technique [0002] In general, a class of series units known as the direct mount type is known, in which a coaxial receptacle is used as the outlet port (also called the TV end) and the far end thereof is processed into a coaxial cable of a predetermined size Directly connected as an input terminal and an output terminal (for example, refer to Patent Document 1). [0003] In recent years, since in order to receive not only terrestrial broadcasting but also satellite broadcasting, the tandem unit needs to allow a channel of a signal (output from a satellite converter) in an intermediate frequency band, the tandem unit is required to have a very wide frequency characteristic. Thus, a series unit is widely used,...
