The present invention relates to a structural panel for a satellite-mounted electronic device.

[0002]

2. Description of the Related Art Electronic devices mounted on satellites are electrically connected to each other by cables. Usually, it is necessary to consider the point that it is necessary to secure the bending radius of the cable (the space corresponding to the curvature of the cable) and the workability when connecting the cable to the electronic device by a connector or the like. In view of the points and the like, the electronic devices must be arranged at a certain interval or more on the structural panel of the satellite. In this case, the cables are fixed at predetermined positions on the structural panel of the satellite.

As is well known, artificial satellites have extremely severe weight restrictions. Therefore, an increase in the size of the structural panel is a problem that must be avoided. However, on the other hand, the mounting density of the artificial satellite mounted on the electronic device has been further increased, and therefore, it has been required to extremely narrow the interval between the electronic devices.

Is removed from the structure panel surface, and the trouble of connecting the wire harness through the cutout hole of the panel is eliminated.

That is, in the above-mentioned conventional technology, an aluminum plate obtained by punching out a predetermined number of connector molds is buried in the center of the honeycomb core, so that the wire harness can be easily attached at the time of integration without damage. At the same time, it aims to simplify the wiring of the wire harness and shorten the wire length.

However, in the conventional structural panel for an electronic device mounted on a satellite in the above-mentioned publication, an aluminum plate obtained by punching a predetermined number of connector types is embedded in the center of the honeycomb core. Electronic equipment cannot be mounted.

Further, since it is necessary to fix the wire harness on the structural panel, the area for fixing the wire harness cannot be used as a mounting area for electronic equipment, which hinders an increase in mounting density for mounting electronic equipment. Problem.

Further, since the wire harness is connected to the side of the electronic device, the distance between the electronic device connector and the adjacent electronic device is reduced on the side of the electronic device connector in consideration of the bending radius (curvature) of the wire harness. It is necessary to secure it appropriately, and for this reason, there is a problem that it is difficult to increase the mounting density for mounting electronic devices.

FIG. 6 is a schematic view showing a state of mounting an electronic device using a conventional structural panel for an electronic device mounted on a satellite.

As shown in the figure, when a plurality of electronic devices 1 and 1 are arranged on a structural panel 11, the respective cables 4 and 4 constituting a wire harness are connected to the side surfaces of the respective electronic devices 1 and 1 (see FIG. 1). In the figure, since there is a connection at the device-to-cable coupling section 12, it is necessary to consider the bending radius (curvature) of the wire harness (cable). For this reason, on the connector surface side of each of the electronic devices 1 and 1, it is necessary for the electronic devices arranged adjacent to each other so that their own connector surfaces face each other, to maintain an appropriate distance between them. still,
Such panels are connected to each other by a cable-to-cable connecting portion 1.
3 can also be connected to other panels.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be clarified by describing in detail embodiments of the present invention with reference to the drawings.

FIG. 1 is a cross-sectional view of a principal part showing a structural panel for an electronic device mounted on a satellite as one embodiment of the present invention.

FIG. 2 is a partial detailed view of the internal structure of the structural panel for an electronic device mounted on a satellite shown in FIG.

As shown in FIGS. 1 and 2, a structural panel 11, which is a plate-shaped structural member, is configured such that a honeycomb core 10 having a honeycomb structure forms a main structural member. At 1, the electronic device 1 is mounted from above (this direction does not necessarily coincide with the direction in the actual mounting posture, but is for convenience of description). The electronic device 1 is provided with an electronic device-side connector (connector to be connected) 2, and the electronic device 1 is fixed to the structural panel 11 by mounting screws 3 as illustrated.

A cable 4 which is an original counterpart electrically connected to the electronic device-side connector 2 of the electronic device 1 is disposed inside a structural member (ie, the structural panel 11) along a predetermined route as exemplified later. Has been established.

The cable 4 has a cable side connector (connecting connector) 5 for mechanically and electrically connecting to the electronic device side connector (connecting connector) 2 inside the structural panel 11. 11 are provided so as not to substantially protrude from the main surface. The cable-side connector (connector for connection) 5 is fixed to a predetermined portion of the structural panel 11 by a connector fixing plate 6.

As is particularly clear from FIG.
In the structural panel 11, the arrangement route is formed as a cutout in which the honeycomb core 10 is cut out, and the route is divided along the extension direction of the cable 4 so as to partition the arrangement route of the cable 4. A cable protection plate 7 for securing and protecting this cable is provided.

As shown, an A-side surface plate 8 and a B-side surface plate 9 are provided so as to sandwich the honeycomb core 10 of the structural panel 11 from the front side and the back side in a sandwich structure.

In the illustrated example, the electronic device-side connector 2 of the electronic device 1 is provided on the bottom side of the electronic device 1. When the electronic device 1 is fixed to the structural panel 11 with the mounting screws 3, the electronic device-side connector 2
The specifications such as the positions and dimensions of the related parts are selected so that the (connecting connector) and the cable-side connector 5 (connecting connector) are fitted and connected.

FIG. 3 is a schematic view showing a state of mounting an electronic device using a structural panel for an electronic device mounted on a satellite as an embodiment of the present invention. As shown in the figure, in the present embodiment, the predetermined plurality of electronic devices 1 and 1 are to be disposed inside the structural panel 11 from a path crossing the center of the panel 11 as shown by the broken line. The cable 4 is routed so as to branch toward a site, and a device-to-cable connector (connector) 12 is disposed at an end of the branch.
Here, the connection with the corresponding device is made. For this reason, when arranging the plurality of electronic devices 1 on the structural panel 11, there is no connection of the wire harness connecting the connectors on the side surfaces of the respective electronic devices 1, 1 facing each other. It is not necessary to consider the bending radius and the like. Therefore, the electronic devices arranged adjacent to each other can be arranged extremely close to each other, and the mounting efficiency is improved. It should be noted that such panels can be connected to other panels at the cable-to-cable coupling portion 13.

In the embodiment described with reference to FIGS. 1, 2 and 3, the cable 4 is connected to the structural panel 1.
Since it is not located on the upper side, metal fittings and the like for fixing the cable 4 are not required, and the simplification of the configuration and the simplification of the manufacturing operation can be achieved. When the connection portion of the cable 4 is on the bottom side of the electronic device 1 and the electronic device 1 is fixed to the structural panel 11 with the mounting screw 3, the electronic device-side connector 2
Since the specifications such as the positions and dimensions of the related parts are determined so that the (connecting connector) and the cable-side connector 5 (connecting connector) are fitted and connected, the electronic device 1 is assembled with the mounting screws 3. As long as a work space for fixing to the panel 11 is secured, even if the electronic devices 1 and 1 are arranged very close to each other, an operation for electrically connecting the electronic devices is essentially hindered. Therefore, the mounting density can be increased from this point as well.

FIG. 4 shows connecting connectors (cable side connectors) 5 and 5 in a plate-like structural member (structural panel 11) facing the front side of the structural panel 11 (the A-side surface plate 8 side). FIG. 5 is a cross-sectional view of a main part of an embodiment in which the main body is disposed toward the rear surface side (the B-side surface plate 9 side). 4, parts corresponding to those in FIG. 1 are denoted by the same reference numerals, and description of each part is omitted.

In the embodiment shown in FIG. 4, the connection between the electronic devices 1 and 1 mounted on the front and back of the structural panel 11 is performed by the cable side connector 5 disposed in each direction of the front and back of the structural panel 11. This is achieved by connecting the electronic device side connectors 2 and 2 of the electronic devices 1 and 1 respectively. Therefore, as in the related art, a complicated configuration or operation as in the conventional apparatus described in the above-mentioned publication, such as providing a cutout hole for passing a cable through the structural panel 11 or embedding a connector bracket in the center of the honeycomb core, as in the related art. Is not required, and there is no problem that the mountable area of the electronic device is limited.

FIG. 5 is a schematic diagram showing a manner in which structural panels according to the embodiment of the present invention are connected by cables.

In FIG. 5, two structural members (structure panel 1)
1, 11) can be installed in a positional relationship such that their main surfaces cross each other on the extension thereof (in the illustrated example, they are substantially in contact at a right angle), and one of the structural panels is one of them. The cable 4 (see FIG. 1) in the other structural panels 11 and 11 in a positional relationship where the cable 4 in FIG. And a connector (cable-to-cable connecting portion 13) for electrically connecting the cable to the cable-connecting portion 13. By doing so, it becomes possible to mount electronic devices at high density in the space inside the artificial satellite having a limited volume and shape.

[0033]

As described above, according to the present invention, when an electronic device is mounted in an artificial satellite, the mounting efficiency can be greatly improved. In addition, since the required electrical connection is established by simply attaching and fixing the electronic device to the structural panel, there is no need to use a separate cable to connect the electronic devices. Work time can be greatly reduced.
