る。 Solar generators currently used in satellites such as the Intelsat V series consist of assembled plates that are lightweight, rigid solar cell supports that are linked together. These assembly plates are deployed on the orbit occupying an area of up to 30m2 . In these assembly plates, stranded wires or spiral flat cables that can be twisted or flat cables with a large radius of curvature are used as connection members for the current conductor system, and are screwed or bonded together.

使用できない。 Since these new thin plate surfaces need to be folded at extremely narrow intervals of about 2 mm to reduce the loading space, the flat cables with connectors attached to the back of the solar generator, which have been proven so far, are , their bending resistance moment and required bending curvature are too large to be used in these new solar generators.

が大切である。 The object of the present invention is to provide a system which can be equipped with individually supported laminated panels in modular dimensions and suitable for connecting these individual panels to each other in a simple and spaceflight-friendly manner. The object of the present invention is to provide a flexible and foldable solar generator for a spacecraft. This solar generator should meet the advanced requirements of spaceflight. Because,
This is because spaceflight is subject to a large alternating thermal load due to the shadows of the sun and the earth, and there is also the greatest requirement for reliability over the entire flight period. Besides that,
The electrical connection member should be constructed in such a way that it remains independent of tensile stress at all times. Furthermore, it is important to solve the problem of allowing the entire solar generator to be detached and reattached many times intact for replacement or repair.

りこの問題が見事に解決されている。 Particularly remarkable effects of this invention are that, in addition to the light weight of the current conductor system, it has a high resistance to sudden mechanical loads during firing, and has sufficient shape stability against tension and surface torsion during deployment. It also has fatigue resistance. Preparing the current conductor system by photoresist etching is significantly less expensive than the conventional individual wiring of stranded wires or flat cables. Furthermore, at the connection points of the supporting sheet panels, conductor separation connectors, which were previously required due to the large space occupied by this structure and the additional weight, can be omitted. Increasing the surface area for this new solar generator by more than three times compared to traditional assembly structures eliminates connector problems by using the space and weight of traditional stranded and flat cables. However, this problem has been successfully solved by this invention.

面）。 FIG. 1 shows the back side of the flexible and foldable solar generator. The solar generator is composed of seven solar panel assemblies SPA1 to SPA7. These assemblies (hereinafter referred to as support thin panels)
are each provided with a number of piano-key-shaped thin hinge sleeves 3 at the vertical separation line (hinge axis 2) (see also FIGS. 2a to 2d). These hinge sleeves 3 are each formed by a support sheet metal fitting 4 which is folded towards the front side and a circular tube 5, made of aluminum or another material, for example, which is inserted into the hinge shaft 2. The folded support plate coupling fitting 4 and the circular tube 5 are firmly glued to the support plate 1 (spotted surface in FIGS. 2a and 2b).

でき、必要に応じて予備用パネルを挿入できる。 According to FIGS. 2a to 2d, the hinge sleeves 3 are arranged in a selected section of one of the support sheet panels with a sheet metal fitting 6 projecting between the sleeves. , these hinge sleeves are offset by one section length in adjacent panels. Therefore, when assembling this panel, the hinge sleeves 3 engage each other exactly and can be connected by means of the thin bayonet shaft 7. All panels have on the outside a section of the hinge sleeve 3 according to FIG. 2a and on the inside a section offset by one section length according to FIG. 2b. Therefore, all panels can be assembled in the same way, and spare panels can be inserted if necessary.

み半径の場合でも、損なわれない。 The material of the support sheet 1 is a sheet of polyimide (trade name Kapton) with a copper coating on one side or, if necessary, on both sides. It improves the surface flatness after etching and increases the overall crack resistance and load capacity of the bonded hinge sleeve 3, as well as the permissible torsional stress during deployment, and increases its strength against all mechanical loads generated. In order to optimize the
Depending on the manufacturing method, either the entire surface of the supporting laminate panel or only the connection areas of the panels are covered with a very thin glass fiber laminate (not shown). By coating the upper surface with a thin layer of glass fiber, the flexibility and ease of folding of the thin plate assembly at the folding line 8 (Fig. 1) of the solar generator between the separation lines 2 is reduced to less than 1 mm. Even with small folding radii it remains intact.

続するために配設されている。 On the back side of the solar generator 1 there is arranged a current conductor system formed by a copper coating using a photoresist etching method (see FIG. 1). The central conductor is specifically arranged for a signal conductor. Starting from the outermost panel SPA1, the individual current conductors 10 for the current obtained from the solar cells are connected to the satellite connection connectors over the entire length of the solar generator and as far as possible inside. The current conductor of the next panel is drawn into the center, and then the first
extending closely adjacent to the current conductor of the panel (and so on). The overall result is therefore a backside coating with etched conductors that increase inwardly in the shape of a fir tree. All current conductors 10 are solar cell modules 12
Starting from the + or - connection point 11 of All current conductors are connected to the fold line 8 (FIG. 3) with a fold conductor connection 13 and at the end of the panel (FIGS. 2a to 2A) with a panel conductor connection 14 via the hinge axis 2.
(see Figure 2d). In this case, the individual + or - conductors are designed as double conductors for redundancy. Each double + conductor and double - conductor are each represented as a current conductor pair 15.
Preliminary current conductor pairs 16 running through the longitudinally outermost sides of the solar generator are provided for connecting a replacement panel to any panel location.

The front side of this metal fitting is reinforced with a thin glass fiber fabric up to the point indicated by the one-dot chain line 22, and the back side is also covered with an insulating film up to the point indicated by the one-dot chain line 22. In this connecting fitting 6, windows 23 (indicated by broken lines and hatching) are formed in the polyimide foil from the front side by etching or laser cutting. The metal of the copper conductor is locally removed.

Similarly, in the etched welding window 23 (polyimide film window) of the protruding support thin plate connecting fitting 6,
The thickness of the conductor copper foil is increased to the required thickness. The purpose of locally thickening the copper is to create a less extreme coating thickness that is more desirable for the welds being performed there, allowing welding conditions to be varied within wide tolerances and reducing weld failure. It can be prevented.

Assemble the panels on the assembly table with the back sides facing up, interlocking the hinge sleeves 3 alternately and aligning them in a straight line. In that case, all the protruding support thin plate connecting fittings 6 are attached to the opposing hinges.
Overlap on sleeve 3, upper side of panel (back side)
(see also figure 2d). When a thin insertion shaft 7 is passed through the hole in the bonded circular tube 5, these panels are mechanically connected. The overlapping conductor protrusions 21 are then welded to thicker copper in the etched weld window 23 near the outer edge of the weld area 24 by multiple weld points 25 or short weld lines. In this case, a thin semicircular plastic insert is intermediately placed at the hinge axis 2 between the overlapping protruding support plate coupling 6 and the underlying hinge sleeve 3. These insertion pieces do not rest flatly on the thin plate connecting fitting 6, but form a gentle expansion/contraction waveform 26 on the hinge shaft 2, and these waveforms push the outer end of the connecting fitting 6 back to the center of the axis. It is adjusted as follows.

This is because in the nearly edge-aligned surface usage situation that occurs in solar generators, the pressure-sensitive solar module 12 attached below the welding area 24 will not be damaged by the pressure of the electrodes. In embodiments in which the front side of the welding area 24 of the current conductor 10 is not covered with a solar cell, it is also possible to use resistance welding with a double electrode introduced from above. Although it is basically possible to braze the welds, it is not preferred for solar generators used in spaceflight.

If it is necessary to replace one panel in a solar generator that has already been installed, connect the supporting thin plate connecting fitting 6 to the adjacent supporting thin plate panel below it.
The weld areas 24 of SPAs 1-7 can be separated using a special scalpel along the separation line 27 shown in dotted lines next to the first row of weld points 25. After reassembling these panels at the replacement location, remove the separation line 27.
