Description

[Detailed Description of the Invention] Technical Field> The present invention is applicable to equipment mounted on artificial satellites, etc.
The present invention relates to an improvement in a high frequency signal connection method in which the arrangement of onboard equipment is subject to significant electrical, mechanical, and thermal constraints, and in which it is important to reduce signal attenuation in high frequency lines used to connect devices.

<Prior art> In devices such as artificial satellites, which have limited shape, size, weight, and power supply, and which require high performance, it is not possible to effectively mount a large number of devices inside the limited volume of the aircraft. ,
Moreover, it is desired to reduce signal attenuation in high frequency lines connecting devices. However, in conventional placement of onboard equipment on a satellite and connection of high-frequency signals between onboard equipment, the equipment is first placed on the equipment mounting panel, and high-frequency lines such as waveguides and coaxial cables are placed on the equipment mounting panel. was installed to connect the devices. However, this connection method has the disadvantage that the waveguides, coaxial cables, etc. occupy a considerable area of the equipment mounting panel, so there is less area available for equipment installation. The placement of high-frequency lines on the panel is also restricted by the placement of other devices, so it is not always possible to connect devices over the shortest distance, resulting in longer line lengths and, as a result, the signal on the high-frequency line It also had the disadvantage of increased attenuation.

<Object of the Invention> This invention was made in view of the above-mentioned drawbacks, and its purpose is to effectively arrange equipment on the equipment mounting panel without occupying a large area of the equipment mounting panel with high frequency lines. It is an object of the present invention to provide a high frequency signal connection method that can be used and shortens the high frequency ugly lines connecting these devices to reduce signal attenuation.

<Configuration of the Invention> The configuration of the present invention is to bury a high frequency line in a structure panel and/or a device mounting panel, and use the buried high frequency line to transmit information on the device mounting panel and/or the structure panel. A method for connecting high-frequency signals is characterized by connecting high-frequency signals between devices installed at the same time using the shortest distance.

<Example> Hereinafter, the present invention will be described with reference to one embodiment thereof.

FIG. 1(a) is a plan view showing an embodiment of the high-frequency signal connection method according to the present invention, and FIG. be. As shown in the figure,
A somewhat large mounted device 2 is arranged approximately at the center of the device mounting panel 1, and slightly smaller mounted devices 3, 4, 5, 6, and 7°8 are arranged on both sides of this mounted device 20, respectively. . The mounted devices 3 and 4 are connected by a waveguide 9 of a high frequency line buried in the device mounting panel 1. When connecting other onboard devices, for example, when connecting onboard devices 5 and 6, onboard devices 7 and 8, or onboard devices 5 and 8, etc., the waveguide 9 is inserted into the device mounting panel 1 as described above. Can be buried and connected.

Therefore, even if the onboard equipment 2 is arranged on the equipment mounting panel 1 in a state that prevents the shortest connection between the onboard equipment 3 and 4 or other onboard equipment, the waveguide 9 is connected to the equipment mounting panel 1. 1 and connects the onboard equipment,
There is no need to connect the mounted devices on the device mounting panel 1 by bypassing other mounted devices (in this case, the mounted device 2) as in the conventional case, and the mounted devices can be connected over the shortest distance. As a result, the connection distance between the devices mounted on the waveguide 9 is shortened, and signal attenuation can be reduced. In addition, equipment mounting panel 1
Since the waveguide 9 of the high-frequency line does not occupy an area for its installation, the area above the device mounting spring A/i can be effectively used for arranging the device. FIG. 2 is an explanatory diagram showing a specific example of embedding high-frequency lines according to the present invention, in which mounted equipment 2.3.
4 is shown, and a high frequency line is buried within the equipment mounting panel 1 to connect these mounted equipment. In other words, the waveguide 9 or coaxial cable 10 of the high frequency line is simply buried in the device mounting panel 1, or the pipe 11 is buried in the device mounting panel 1,
A waveguide 9 of a high-frequency line or a coaxial cable 10 is arranged in this pipe 11, or an equal-wave tube 9 of a high-frequency line is placed in a dark groove 12 (groove with a lid) provided on the surface of the equipment mounting panel 10. Alternatively, a coaxial cape/I/10 is installed, or a waveguide 9 of a high frequency line or a coaxial cable 10 is installed in an opening 13 (coverless cable) provided on the surface of the equipment mounting panel 1. It is what was done. Note that it is not necessary to bury the high-frequency line such as the waveguide 9 or the coaxial cable 10 in the device mounting panel 1 before installing the equipment; instead, it is necessary to form a pipe or groove in advance and bury it as appropriate after installing the equipment. , it is also possible to arrange it through these. Moreover, the high-frequency line to be buried can be buried not only inside the equipment mounting panel but also inside the structure of, for example, an artificial satellite.

<Effects of the Invention> As explained above, according to the present invention, by installing high-frequency lines such as waveguides and coaxial cables on the structural panels of artificial satellites and equipment mounting panels, the outside of equipment mounting panels, etc. Since the surface area is not occupied by high-frequency lines, the equipment mounting panel can be effectively used for equipment placement, and the high-frequency lines that connect these devices can be shortened, resulting in the effect of reducing signal attenuation. It is something that demonstrates the.
