である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deployable solar battery array in which a plurality of solar battery panels each having solar battery cells arranged on its surface are deployed and maintained in that state during use. The present invention provides a deployable solar cell array in which the wire harness that electrically connects the solar cell panels has a spiral shape in order to supply the power required by the solar cell array.
まず従来の展開型太陽電池アレイについて第１
図〜第３図を用いて説明する。 First, let's talk about conventional deployable solar cell arrays.
This will be explained using FIGS.

いる。 In the figure, 1 and 2 are solar panels on which solar cells (not shown) are arranged;
3 is a wire harness for electrically connecting the panels 1 and 2; 4 is a fixing screw for attaching the wire harness 3 between the solar panels 1 and 2; and 5 and 6 are the solar panels 2 and 3. A clevis fitting 7 attached to the corner of the clevis fitting 6 is a hinge pin that is integral with the clevis fitting 6, and a coil spring is wound around the hinge pin 7.
8 and 9 are wire harnesses for connecting solar cells. The clevis fitting 5 has an integrated bearing (not shown), and the rotatable connection between this bearing and the hinge pin 7 allows the solar panels 1 and 2 to be folded before use and unfolded when used. This is becoming a state of affairs.

なる。 Since the conventional expandable solar cell array described above is constructed as described above, the holding and releasing mechanism of the solar cell panels (not shown) can be released from the folded state of the solar cell panels 1 and 2 as shown in FIG. Then, due to the rotational torque of the coil spring wrapped around the hinge pin 7 integrated with the clevis fitting 6, the solar panel 2 is expanded in the direction of the arrow as shown in FIG. 2, and one end of the wire harness 3 connecting the panels 1 and 2 is expanded. The sides rotate as the panel 2 unfolds. When the panel 2 is unfolded and becomes flush with the panel 1 as shown in FIG. 3, the unfolded state is maintained. At this time, the wire harness 3 connecting the panels 1 and 2 is also flush.

であつた。 However, with the shape of the wire harness as described above, thermal expansion and contraction occur in the wire harness due to temperature changes when the panel is unfolded, and the wire harness itself is unable to absorb the resulting tensile and compressive forces. This not only affected the panel development, but also caused repeated loads to be applied to the connection points between the wire harness and the panel, resulting in a decrease in reliability due to fatigue failure.

事を目的としている。 This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by making the wire harness shape of the connection between panels spiral,
The purpose is to reduce the impact on panel development as much as possible, remove repeated loads on the wiring harness and the connection between the panels, and improve reliability.

The shape of the wire harness 3 that connects the solar panels 1 and 2 is the same as that shown in the figure, but the shape is changed from one end of the wire harness 3 inward and from the inside to the other end of the wire harness 3. A spiral wire harness 3 with a spiral shape in which the spiral direction is in the opposite direction.
As shown in FIG. 6, both ends of the panel are attached parallel to the panel mounting surface when the panel is fully expanded. During the satellite launch, the solar panels 1 and 2 are held in a folded state as shown in FIG. 4, but the spiral wire harness 3 is folded as shown in FIG. , held in a curled state.

ている。 Therefore, when the panel is unfolded (FIG. 5), a restoring force acts on the wire harness 3 in the panel unfolding direction as the panel is released from holding, reducing the influence on the panel unfolding. Also, to prevent thermal expansion and contraction that occurs in the wire harness due to temperature changes when the panel is unfolded,
The wire harness has a shape that sufficiently absorbs tensile and compressive forces within its own loop, and does not apply any load to the connection between the wire harness and the panel.

に与えず高信頼性を得られるという利点がある。 As described above, according to the present invention, a restoring force is applied to the panel in the panel unfolding direction when the panel is unfolded, reducing the influence on the panel unfolding, and the load due to thermal expansion/shrinkage is not applied to the connection point between the wire harness and the panel. It has the advantage of being reliable.
