Description

[Technical Field]

[0001] The present invention relates to a switch mounting structure, and more particularly to a switch mounting structure for mounting a b-contact, momentary-operation push switch on an artificial satellite. [Background technology]

[0002] When a satellite is transported to a rocket launch site or launched by a rocket, the satellite is kept powered off. This is because if the satellite is powered on during transportation or launch, not only will power be wasted until the satellite is released from the rocket into space in orbit, but vibrations and electromagnetic noise during rocket launch may cause malfunctions or breakdowns in electronic devices on the satellite. Therefore, when a satellite is launched by a rocket, the satellite is powered off, and when the satellite is released from the rocket into space in orbit, the satellite is powered on (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-171180 Summary of the Invention [Problem to be solved by the invention]

[0004] As such, it is necessary to reliably maintain the power of the satellite in an off state when the satellite is launched by a rocket, and to reliably turn the power of the satellite on when the satellite is released from the rocket into space in orbit. Therefore, the inventors of the present application have developed a switch structure for a satellite that has a simplified configuration and is easy to assemble (Patent No. 7706195).

[0005] Furthermore, in recent years, there has been a strong demand for the development of small satellites that can be used for a wide variety of missions while achieving short delivery times and low costs, and there is a need for further miniaturization and improvements in reliability and productivity in the switch mounting structure of artificial satellites.

[0006] The present invention has been made in consideration of the above problems, and has as its object to provide a switch mounting structure for an artificial satellite that is miniaturized and has improved reliability and productivity. [Means for solving the problem]

[0008] According to one aspect of the present invention, the switch further includes a circuit board that electrically connects the terminals of the push switch and the wiring of the satellite, the switch body, the fixing plate, and the circuit board are stacked in the direction in which the positioning pin protrudes, the circuit board is sandwiched between the fixing plate and the switch body, and the wiring is arranged within the range of the thickness of the stacked switch body, the circuit board, and the fixing plate.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A switch mounting structure according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0013] First, the overall configuration of a satellite to which a switch mounting structure according to an embodiment of the present invention is applied will be described with reference to Fig. 1. Fig. 1 is a perspective view showing a state of a satellite to which a switch mounting structure according to an embodiment of the present invention is applied before it is inserted into orbit.

[0014] As shown in Fig. 1, the satellite 1 of this embodiment includes a satellite main body 2 and solar array panels (SAP) 4. The satellite main body 2 has a rectangular parallelepiped outer shape, and is equipped with various devices inside, such as the power supply system, attitude control system, and communication system of the satellite 1. In the following description, the top surface of the satellite main body 2 shown in Fig. 1 will be referred to as the +X surface, the bottom surface as the -X surface, the right side surface as the -Y surface, the left side surface as the +Y surface, the surface toward the back of the page as the -Z surface, and the surface toward the front of the page as the +Z surface.

[0015] The solar cell panels 4 convert sunlight in space into electricity and supply it to the onboard equipment of the satellite 1. The solar cell panels 4 are connected to the satellite main body 2 via hinge mechanisms (not shown) provided at the +Z side ends of the +X and -X planes of the satellite main body 2. Due to these hinge mechanisms, the solar cell panels 4 are folded and stored along the +X and -X planes as shown in Fig. 1 when the satellite 1 is stored or loaded onto a rocket, and are deployed along approximately the same plane as the +Z plane when the satellite 1 is released into space.

[0016] Furthermore, with the switch mounting structure of this embodiment, push switches 6 are mounted on the corners on the -X and -Y sides of the +Z surface of the satellite main body 2. The push switches 6 keep the satellite 1 powered off during transportation on the ground or launch by rocket, and turn the satellite 1 powered on when the satellite 1 is separated from the rocket in orbit and released into space.

[0017] Next, the configuration of the switch mounting structure according to this embodiment will be described with reference to Fig. 2 to Fig. 5. Fig. 2 is a perspective view showing the configuration of the switch mounting structure according to this embodiment, Fig. 3 is a plan view of the switch mounting structure according to this embodiment as seen from the +X side, Fig. 4 is a cross-sectional view taken along line III-III of the switch mounting structure shown in Fig. 3, and Fig. 5 is an exploded perspective view of the switch mounting structure according to this embodiment.

[0018] The switch mounting structure according to this embodiment is for mounting a push switch 6 with b-contact and momentary action on a satellite 1. The push switch 6 of this embodiment includes a push button 8 for switching the contact between ON and OFF, and a switch body 10 that houses part of the push button 8 and the contact (not shown). The push switch 6 with b-contact and momentary action is configured so that the contact opens (i.e., the circuit turns OFF) while the push button 8 is pressed, and closes (i.e., the circuit turns ON) when the push button 8 is released.

[0019] The push switch 6 in this embodiment is connected to the power supply circuit of the satellite 1, and while the push button 8 is pressed, the contacts open, turning the satellite 1 into a power-off state, and when the push button 8 is released, the contacts close, turning the satellite 1 into a power-on state.

[0020] As shown in FIG. 2, the switch mounting structure of this embodiment includes a switch body 10 of the push switch 6, a circuit board 12 fixed to the switch body 10, and a fixing plate 14 and a fixing bolt 16 (fastener) that position and fix the switch body 10 to the mounting portion of the artificial satellite 1.

[0021] The switch main body 10 of this embodiment has a substantially rectangular parallelepiped outer shape and houses the contacts of the push switch 6 inside. Furthermore, a cylindrical push button 8 of the push switch 6 protrudes from one side of the switch main body 10 (in this embodiment, the +Z side when attached to the satellite 1). When this push button 8 is pressed, the contacts of the push switch 6 open, and when the push button 8 is released and moves in the direction in which it protrudes from the switch main body 10 (in this embodiment, the +Z direction), the contacts of the push switch 6 close.

[0022] Furthermore, two positioning pins 18A, 18B are formed on one side surface (the +X side surface in this embodiment) of the switch body 10 that is parallel to the movement direction (the Z direction in this embodiment) of the push button 8. The positioning pins 18A, 18B protrude in a direction (the +X direction in this embodiment) that is approximately perpendicular to the movement direction of the push button 8. Each of the positioning pins 18A, 18B is formed in a substantially cylindrical shape.

[0023] Terminals 20 of the push switch 6 are provided on two side surfaces (+Y surface and -Y surface when attached to the satellite 1 in this embodiment) adjacent to the surface on which the positioning pins 18A and 18B of the switch main body 10 are formed. These terminals 20 are formed to extend toward the surface on which the positioning pins 18A and 18B of the switch main body 10 are formed.

[0024] The circuit board 12 is a board for electrically connecting the terminals 20 of the push switch 6 and the wiring 22 of the artificial satellite 1. The circuit board 12 is formed in a flat plate shape having a substantially rectangular outline in a plan view, and is placed on the surface of the switch body 10 on which the positioning pins 18A and 18B are formed. As shown in FIGS. 4 and 5 , the circuit board 12 is formed with holes 24A and notches 24B so that the positioning pins 18A and 18B can be inserted into the switch body 10. Furthermore, these holes 24A and notches 24B are formed so that protrusions 26 of the fixing plate 14, which will be described later, can be fitted into them. A circuit is formed on the surface of the circuit board 12 facing the switch body 10, and the terminals 20 of the push switch 6 are soldered to this circuit.

[0025] Furthermore, when the circuit board 12 is placed on top of the switch body 10, the length of the circuit board 12 in the direction of movement of the push button 8 (the length in the Z direction in Figures 2 and 3) is longer than that of the switch body 10. In other words, the circuit board 12 protrudes beyond the switch body 10 in the direction opposite to the push button 8 of the switch body 10. In this way, the wiring 22 of the satellite 1 is placed in the space where the circuit board 12 protrudes from the switch body 10 in the direction opposite to the push button 8, and the wiring 22 of the satellite 1 is electrically connected to the circuit of the circuit board 12. This electrically connects the electrical circuit of the satellite 1 and the push switch 6.

[0026] The fixing plate 14 is used to fix the push switch 6 to a mounting portion of the satellite 1. The fixing plate 14 is formed in a flat plate shape having a substantially rectangular outer shape in a plan view, and is configured to be placed on the circuit board 12 which is placed on the switch body 10. That is, the switch body 10, the circuit board 12, and the fixing plate 14 are layered in the order of switch body 10, circuit board 12, and fixing plate 14 in the protruding direction of the positioning pins 18A and 18B, and the circuit board 12 is sandwiched between the fixing plate 14 and the switch body 10. Furthermore, the wiring 22 is arranged within the range of the thickness of the switch body 10, the circuit board 12, and the fixing plate 14 stacked together.

[0027] 4 and 5, a protrusion 26 is formed on the surface of the fixing plate 14 facing the circuit board 12. The protrusion 26 is fitted into the hole 24A and the notch 24B formed in the circuit board 12. That is, the outer periphery of the protrusion 26 is formed so as to substantially coincide with the inner periphery of the hole 24A and the notch 24B formed in the circuit board 12 in a plan view. As a result, when the protrusion 26 is fitted into the hole 24A and the notch 24B of the circuit board 12, the circuit board 12 is fixed so as not to move in directions perpendicular to the protruding direction of the protrusion 26 (the Y direction and the X direction in FIG. 5). Furthermore, the protrusion 26 is formed to a protruding height such that when the protrusion 26 is fitted into the hole 24A and the notch 24B of the circuit board 12, the surface of the protrusion 26 facing the switch body 10 and the surface of the circuit board 12 facing the switch body 10 (both of which are surfaces on the -X side in FIG. 4 and FIG. 5) are flush with each other. In other words, the height of the protrusion 26 is approximately equal to the thickness of the circuit board 12 plus the height of the gap between the fixing plate 14 and the circuit board 12 .

[0028] 4 and 5, the protrusion 26 of the fixing plate 14 is formed with two positioning holes 28A, 28B into which the positioning pins 18A, 18B of the switch body 10 are fitted. In this embodiment, the positioning hole 28A, into which the positioning pin 18A of the two positioning pins 18A, 18B that is closer to the push button 8 (the +Z side in FIGS. 3 and 4) is fitted, is formed to have an inner periphery that approximately matches the outer periphery of the positioning pin 18A in a plan view. On the other hand, the positioning hole 28B, into which the positioning pin 18B of the two positioning pins 18A, 18B that is farther from the push button 8 (the -Z side in FIGS. 3 and 4) is fitted, has approximately the same width as the outer periphery of the positioning pin 18B in a plan view and is formed as an elongated hole with a major axis in the direction in which the two positioning holes 28A, 28B are aligned (the Z direction in FIGS. 3 and 4). As a result, the relative positions of the fixed plate 14 and the switch body 10 are fixed by the two positioning pins 18A, 18B and the positioning holes 28A, 28B, and manufacturing errors between the spacing between the two positioning pins 18A, 18B and the spacing between the two positioning holes 28A, 28B are absorbed by the oblong positioning hole 28B on the side farther from the push button 8.

[0029] As shown in Figures 2 to 5, by fitting the protrusion 26 of the fixing plate 14 configured as described above into the hole 24A and notch 24B of the circuit board 12 and fitting the positioning pins 18A and 18B of the switch body 10 into the positioning holes 28A and 28B of the protrusion 26, the switch body 10, circuit board 12, and fixing plate 14 are stacked in this order in the protruding direction of the positioning pins 18A and 18B and are fixed so as not to move relative to each other.

[0030] Furthermore, when the positioning pins 18A, 18B of the switch body 10 are fitted into the positioning holes 28A, 28B of the fixing plate 14, a through hole 30 for inserting the shaft portion of the fixing bolt 16 described later is formed at a position farther from the push button 8 than the two positioning holes 28A, 28B of the fixing plate 14 (on the -Z side in Figures 4 and 5).

[0031] Furthermore, the end of the fixing plate 14 on the side farther from the push button 8 (the -Z side in this embodiment) extends in a direction substantially perpendicular to the movement direction of the push button 8, in the direction in which the circuit board 12 and the switch body 10 are stacked (the +X direction in this embodiment). This end allows the fixing plate 14 to be positioned.

[0032] The fixing bolt 16 is a fastener that fixes the fixing plate 14 to the mounting portion of the satellite 1 in a state in which the switch body 10, the circuit board 12, and the fixing plate 14 are fixed so as not to move relative to each other as described above. Specifically, as shown in FIGS. 2 to 4 , the shank of the fixing bolt 16 is inserted into the through-hole 30 of the fixing plate 14 from the opposite side to the switch body 10 and the circuit board 12 (the +X side in FIGS. 2 and 4 ), and the threaded portion at the tip of the fixing bolt 16 is screwed into the threaded hole 32 of the mounting portion of the satellite 1 (inside the housing of the satellite body 2 in this embodiment) to be fixed. In this way, the fixing bolt 16 fixes the fixing plate 14 to the mounting portion of the satellite 1 in a state in which the switch body 10 and the circuit board 12 are disposed between the fixing plate 14 and the mounting portion of the satellite 1.

[0033] The position of the fixing plate 14 relative to the mounting portion of the satellite 1 is determined by the screw holes 32 and the fixing bolts 16 in the mounting portion. The position of the circuit board 12 relative to the fixing plate 14 is determined by the protrusion 26 of the fixing plate 14 and the holes 24A and notches 24B in the circuit board 12. The position of the switch main body 10 relative to the fixing plate 14 is determined by the positioning holes 28A and 28B of the fixing plate 14 and the positioning pins 18A and 18B of the switch main body 10. Therefore, the position of the switch main body 10 relative to the mounting portion of the satellite 1 can be determined with high precision via the fixing plate 14.

[0034] When the switch body 10, circuit board 12, and fixing plate 14 are stacked, the length in the movement direction of the push button 8 (the length in the Z direction in FIGS. 2 and 3) of the fixing plate 14 is the longest, followed by the circuit board 12, and the shortest of the switch body 10. In the space on the switch body 10 side of the portion of the circuit board 12 that protrudes from the switch body 10 in the direction opposite to the push button 8 (the space on the opposite side of the switch body 10 from the push button 8 (the -Z direction in this embodiment)), the wiring 22 can be connected to the circuit of the circuit board 12. This allows the wiring 22 to be provided on the side of the fixing plate 14 farther from the push button 8 (the -Z side in this embodiment) while easily avoiding the end of the fixing plate 14 that extends in a direction approximately perpendicular to the movement direction of the push button 8.

[0035] Next, the operation of the push switch 6 in this embodiment will be described with reference to Fig. 6. Fig. 6 is a perspective view showing the push switch 6 in this embodiment in an OFF state and an ON state.

[0036] 6, the push switch 6 is attached to the corners on the -X and -Y sides of the +Z face of the satellite main body 2, and is positioned so that the push button 8 protrudes from the +Z face of the satellite main body 2 when it is released. When the satellite 1 is being transported on the ground or launched by rocket, the push button 8 comes into contact with the wall of the satellite housing section of the container or rocket and is pushed in the -Z direction, opening the contacts of the push switch 6 and keeping the satellite 1 in a power-off state.

[0037] When the satellite 1 is launched and released into space from the rocket, the push button 8 is released and protrudes in the +Z direction, closing the contacts of the push switch 6 and turning the satellite 1 on.

[0038] Next, another application example of the switch mounting structure according to this embodiment will be described with reference to Fig. 7. Fig. 7 is a diagram showing another application example of the switch mounting structure according to one embodiment of the present invention. In the example of Figs. 1 to 6, as described above, the push switch 6 is mounted on the inside of the housing at the corner on the -X side and the -Y side of the +Z face of the satellite main body 2 as the mounting portion, and when the satellite 1 is released into space, the push button 8 of the push switch 6 is released and the satellite 1 is turned on.

[0039] However, the purpose and location of application of the push switch 6 are not limited to the examples shown in Figures 1 to 6, and it can also be applied to other locations on the satellite 1. For example, in the example shown in Figure 7, the push switch 6 is attached adjacent to the inside of the lid 34 of an onboard device (for example, an antenna storage container that stores an antenna) on the satellite 1. In the example shown in Figure 7, the structure for fixing the switch main body 10 using the circuit board 12, fixing plate 14, and fixing bolt 16 is the same as in the examples shown in Figures 1 to 6.

[0040] 7, the push switch 6 is arranged so that the movement direction of the push button 8 is perpendicular to the inner surface of the lid 34 of the onboard equipment, and when the lid 34 is closed, the push button 8 abuts against the inner surface of the lid 34 and is pushed toward the switch main body 10 (downward in FIG. 7). In other words, when the lid 34 of the onboard equipment is closed during transportation of the satellite 1 on the ground or launch by rocket, the push button 8 abuts against the inner surface of the lid 34 and is pushed toward the switch main body 10, opening the contacts of the push switch 6.

[0041] On the other hand, after the satellite 1 is launched and released into space from the rocket, when the lid 34 of the onboard equipment is opened (for example, when the lid 34 of the antenna storage container is opened to extend and deploy the antenna from the antenna storage container), the push button 8 is released and protrudes in a direction away from the switch body 10 (upward in Figure 7), thereby closing the contacts of the push switch 6.

[0042] As described above, the contact of the push switch 6 opens and closes depending on whether the lid 34 is open or closed, so the open / closed state of the lid 34 can be detected based on the open / closed state of the push switch 6. That is, if the contact of the push switch 6 is open, the lid 34 of the onboard equipment is closed, and if the contact of the push switch 6 is closed, the lid 34 of the onboard equipment is detected as open.

[0043] <Action and effect> Next, the effects of the above-described embodiment will be described.

[0044] According to this embodiment, the push switch 6 is attached to the satellite 1 by using a switch body 10 having two positioning pins 18A, 18B protruding in a direction approximately perpendicular to the movement direction of the push button 8, a fixing plate 14 having two positioning holes 28A, 28B into which the two positioning pins 18A, 18B are fitted and a through-hole 30 for inserting the fixing bolt 16, and a fixing bolt 16 that fixes the fixing plate 14 to the mounting portion of the satellite 1 with the two positioning pins 18A, 18B fitted into the two positioning holes 28A, 28B, respectively, and the switch body 10 positioned between the fixing plate 14 and the mounting portion of the satellite 1. Two positioning holes 28A, 28B and through hole 30 are aligned in a direction parallel to the movement direction of push button 8, of the two positioning holes 28A, 28B, positioning hole 28A which is closer to the push switch button has an inner periphery that roughly matches the outer periphery of positioning pin 18A, of the two positioning holes 28A, 28B, positioning hole 28B which is farther from the push switch button is an elongated hole whose major axis is in the direction in which the two positioning holes 28A, 28B are aligned, and through hole 30 is formed in a position farther from push button 8 than the two positioning holes 28A, 28B. As a result, the position of fixing plate 14 with respect to the mounting portion of artificial satellite 1 is determined by fixing bolt 16, and the position of switch main body 10 with respect to fixing plate 14 is determined by positioning holes 28A, 28B of fixing plate 14 and positioning pins 18A, 18B of switch main body 10. Therefore, simply by fixing the fixing plate 14 with the fixing bolt 16, the position of the push switch 6 relative to the mounting portion of the satellite 1 can be precisely determined, thereby enabling the switch mounting structure to be made smaller and its reliability and productivity to be improved.

[0045] Furthermore, according to this embodiment, the switch further includes a circuit board 12 that electrically connects the terminal 20 of the push switch 6 and the wiring 22 of the satellite 1. The switch body 10, the fixing plate 14, and the circuit board 12 are stacked in the protruding direction of the positioning pins 18A and 18B, the circuit board 12 is sandwiched between the fixing plate 14 and the switch body 10, and the wiring 22 is arranged within the thickness of the stacked switch body 10, the circuit board 12, and the fixing plate 14. As a result, the terminal 20 of the push switch 6 and the wiring 22 of the satellite 1 are connected via the circuit board 12, so the push switch 6 and the wiring 22 can be more securely held compared to when the wiring 22 is directly connected to the terminal 20 of the push switch 6, and the reliability of the switch mounting structure can be further improved. Furthermore, because the switch body 10, the fixing plate 14, and the circuit board 12 are stacked and the wiring 22 is arranged within the thickness of the stacked switch body 10, the space can be saved.

[0046] Furthermore, according to this embodiment, the length of the circuit board 12 in the direction of movement of the push button 8 when stacked on the switch body 10 is longer than that of the switch body 10. This allows the wiring 22 of the satellite 1 to be connected to the circuit board 12 in the space where the circuit board 12 protrudes beyond the switch body 10 in the direction opposite to the push button 8 of the switch body 10, thereby enabling the switch mounting structure to be made more compact.
