Description

Technical Field

[0001] This invention relates to a telescopic mounting base plate. Background Technology

[0002] In recent years, there has been a need for devices that come into contact with living organisms to measure their data. Examples of such devices include those comprising a stretchable substrate and electronic components mounted on that substrate. These devices, also known as stretchable substrates, are configured to be in close contact with the living organism through the stretching and contraction of the substrate, enabling them to follow the organism's movements.

[0003] For example, Patent Document 1 discloses a situation in which the base island is embedded in the substrate and an element (also called an electronic component) is formed on the base island in a stretchable substrate having a substrate made of a stretchable material (also called a stretchable substrate) and a base island made of a material with a Young's modulus greater than that of the substrate.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2014-162124

[0005] In the stretchable substrate described in Patent Document 1, the stretching rate differs between the areas with embedded base islands and the areas without embedded base islands during the stretching process. Specifically, the stretching rate is smaller in the areas with embedded base islands made of a material with a Young's modulus greater than that of the substrate, and larger in the areas without embedded base islands. If areas with smaller stretching rates, such as those with embedded base islands, occur, the wearer may experience discomfort. Summary of the Invention

[0006] The present invention was made to solve the above-mentioned problems, and its purpose is to provide a flexible mounting substrate that is difficult to produce with a small stretching ratio.

[0007] The telescopic mounting substrate of the present invention comprises: a first substrate having a telescopic substrate and telescopic wiring disposed on the telescopic substrate; a second substrate having electronic components mounted thereon and having wiring provided thereon; and a connecting member physically connecting the first substrate and the second substrate. The connecting member comprises a connecting substrate and connecting wiring, the connecting wiring electrically connecting the telescopic wiring of the first substrate and the wiring of the second substrate. When the first substrate expands or contracts, the connecting member deforms according to the expansion / contraction direction of the first substrate, such that the expansion / contraction rate of the area of ​​the first substrate that overlaps with the second substrate when viewed from above is greater than the expansion / contraction rate of the second substrate.

[0008] According to the present invention, it is possible to provide a flexible mounting substrate that is difficult to produce portions with a small rate of expansion. Attached Figure Description

[0043] The telescopic mounting base of the present invention will now be described. Furthermore, the present invention is not limited to the structure described below, and appropriate modifications may be made without departing from the spirit of the invention. Additionally, the present invention also includes structures that combine multiple preferred structures described below.

[0044] The embodiments shown below are illustrative, and of course, partial substitutions or combinations of the structures shown in different embodiments are possible. In embodiments other than Embodiment 1, descriptions of matters common to Embodiment 1 are omitted, and the differences are mainly explained. In particular, the same effects resulting from the same structure are not mentioned sequentially in each embodiment.

[0045] [Extremely flexible mounting base]

[0046] (Implementation Method 1)

[0047] Figure 1 This is a perspective view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 1 of the present invention. Figure 2 yes Figure 1 The 3D image below. Figure 3 yes Figure 1 The top view in the image. Figure 4 yes Figure 1 Side view of the middle.

[0048] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the telescopic mounting base plate 1 includes a first base plate 10, a second base plate 20, and a connecting member 40 that physically connects the first base plate 10 and the second base plate 20.

[0049] The first substrate 10 has a stretchable substrate 11 and stretchable wiring 13 disposed on the stretchable substrate 11.

[0050] The second substrate 20 has a plate-like shape that is rectangular in plan view and is configured to be substantially parallel to the first substrate 10. The second substrate 20 has a main surface on the side of the first substrate 10 and a main surface on the opposite side of the first substrate 10.

[0051] An electronic component 30 is mounted on the main surface of the second substrate 20 opposite to the first substrate 10.

[0052] Furthermore, the second substrate 20 is provided with wiring 35 and connection connector 70.

[0053] Wiring 35 electrically connects the electronic component 30 and the connector 70 mounted on the second substrate 20.

[0054] It should be noted that the position of the electronic component 30 is not limited to the main surface of the second substrate 20 opposite to the first substrate 10.

[0055] That is, electronic components 30 may be provided on the main surface of the second substrate 20 on the side of the first substrate 10, within a range that does not impede the expansion and contraction of the elastic substrate 11. In this case, wiring 35 and connecting connector 70 are preferably also provided on the main surface of the second substrate 20 on the side of the first substrate 10.

[0056] like Figure 3 As shown, when viewed from above, the first substrate 10 and the second substrate 20 have overlapping portions. With the above structure, the second substrate and the electronic components mounted on the second substrate are less likely to come into direct contact with living organisms, thus reducing the sense of discomfort felt by the wearer.

[0057] Furthermore, it is preferable that the first substrate 10 and the second substrate 20 are not bonded to each other across their entire surface. If the first substrate 10 and the second substrate 20 are not bonded to each other across their entire surface, the expansion rate of the area of ​​the first substrate 10 that overlaps with the second substrate 20 when viewed from above is less likely to be affected by the expansion rate of the second substrate 20.

[0058] Furthermore, the first substrate 10 and the second substrate 20 can contact each other or via a component made of a stretchable material. Additionally, as long as the first substrate 10 and the second substrate 20 are configured to move relative to each other, a portion of the first substrate can be fixed to the second substrate using an adhesive or the like.

[0059] The connecting component 40 physically connects the first substrate 10 and the second substrate 20.

[0060] Specifically, one end of the connecting component 40 is connected to the first substrate 10, and the other end is connected to the connecting connector 70 mounted on the second substrate 20.

[0061] The connecting component 40 includes a connecting substrate 50 and connecting wiring 51.

[0062] One end of the connecting wire 51 is connected to the flexible wire 13 of the first substrate 10, and the other end is electrically connected to the wire 35 of the second substrate 20 via the connecting connector 70. Therefore, it can be said that the connecting wire 51 electrically connects the flexible wire 13 of the first substrate 10 and the wire 35 of the second substrate 20. The boundary between the first substrate 10 and the connecting member 40 is marked by a dashed line e. 11 The positions indicated by the dashed line e represent the boundaries between the connecting part 40 and the connecting connector 70. 12 The indicated location.

[0063] Furthermore, since the wiring 35 of the second substrate 20 is connected to the electronic component 30, it can be said that the connecting wiring 51 electrically connects the stretchable wiring 13 of the first substrate 10 and the electronic component 30 mounted on the second substrate 20.

[0064] Figure 4 This indicates that the first substrate is not stretched or retracted.

[0065] like Figure 4 As shown, in the unstretched state of the first substrate 10, the length of the connecting member 40 along the stretching direction (x direction) measured along the surface of the connecting member 40 (in... Figure 4 In the diagram, the length l1 of the thick line portion is compared with the end of the first substrate 10 connected by the connecting member 40 (marked with dashed line e) when viewed from above on the telescopic mounting substrate 1. 11 The position indicated is from the end of the second substrate 20 (marked by dashed line e). 12 The shortest length of the position (in) Figure 4 In the diagram, the length indicated by the double-headed arrow d1 is approximately the same. The length indicated by the double-headed arrow d1 is also the length of the connecting component 40 when viewed from above.

[0066] In the unstretched state of the first substrate 10, the region of the first substrate 10 that overlaps with the second substrate 20 when viewed from above is denoted by S1. The length of the long side (x-direction) of region S1 is denoted by the double-headed arrow L1.

[0067] Figure 5 It is a schematic representation Figure 4 The figure shows an example of a deformed telescopic mounting substrate.

[0068] like Figure 5 As shown, when the telescopic mounting substrate 1 is stretched in the x direction, the first substrate 10 is stretched in the x direction, and the connecting member 40 is also stretched in the x direction.

[0069] like Figure 5 As shown, even after the telescopic mounting base plate 1 is stretched in the x-direction, the length of the connecting member 40 along the telescopic direction (x-direction) measured along the surface of the connecting member 40 (in... Figure 5 In the diagram, the length l2 of the thicker line also corresponds to the end of the first substrate 10 connected by the connecting member 40 (marked with dashed line e) when viewed from above on the telescopic mounting substrate 1. 11 The position indicated is from the end of the second substrate 20 (marked by dashed line e). 12 The shortest length of the position (indicated) Figure 5 In the diagram, the length (represented by the double-headed arrow d2) is approximately the same. This is because, when the telescopic mounting base plate 1 is stretched in the x-direction, the connecting member 40 is also stretched in the x-direction, just as the first base plate 10 is stretched in the x-direction.

[0070] like Figure 5 As shown, when the telescopic mounting substrate 1 is stretched in the x direction, the length of the connecting member 40 in the x direction changes from l1 to l2. Therefore, it can be said that the force that stretches the telescopic mounting substrate 1 in the x direction is used for the deformation of the first substrate 10 and the connecting member 40.

[0071] In the unstretched state of the first substrate 10, by stretching the first substrate 10, the length of the long side (x-direction) of the region S1 in the first substrate 10 that overlaps with the second substrate when viewed from above changes from L1 to L2. That is, the stretching rate of the region of the first substrate overlapping with the second substrate when the first substrate stretches is expressed as (L2 - L1) / L1. According to Figure 4 as well as Figure 5 Since L1 < L2, the scaling factor is greater than zero. On the other hand, almost no force is applied to the second substrate 20 in the x-direction, so its dimensions hardly change. Therefore, the change in the dimensions of the second substrate, i.e., the scaling factor, becomes a value close to zero.

[0072] As described above, in the telescopic mounting substrate 1, when the first substrate 10 extends or retracts, the connecting member 40 deforms according to the extension / retraction direction of the first substrate 10, so that the extension / retraction of the area of ​​the first substrate 10 that overlaps with the second substrate when viewed from above is not restricted by the second substrate. Therefore, it can be said that the extension / retraction rate of the area of ​​the first substrate 10 that overlaps with the second substrate when viewed from above is greater than the extension / retraction rate of the second substrate.

[0073] If the expansion rate of the area of ​​the first substrate 10 that overlaps with the second substrate 20 when viewed from above is greater than the expansion rate of the second substrate 20, then when the first substrate 10 expands or contracts, the area of ​​the first substrate 10 that overlaps with the second substrate 20 when viewed from above will deform sufficiently, thus making it difficult to produce a portion with a smaller expansion rate.

[0074] The scaling factor of the first and second substrates can be determined by dividing the shortest distance from one end to the other in the deformed state by the reference length, using the shortest distance from one end to the other in the unstressed state as the reference length.

[0075] Furthermore, the scaling factor of the region of the first substrate 10 that overlaps with the second substrate 20 when viewed from above refers to the scaling factor of the first substrate 10 in that region. That is, when the first substrate in that region has stretchable wiring, it is the scaling factor of the state including the stretchable substrate and the stretchable wiring. On the other hand, when the first substrate in that region does not have stretchable wiring, it is the scaling factor of the stretchable substrate in that region.

[0076] like Figure 4 As shown, in the telescopic mounting substrate of Embodiment 1 of the present invention, when the first substrate is not telescopic, it is preferable that the length of the connecting member in the telescopic direction measured along the surface of the connecting member is approximately the same as the shortest length from the end of the first substrate connected by the connecting member to the end of the second substrate when the telescopic mounting substrate is viewed from above.

[0077] When the first substrate is not stretched, if the length of the connecting member measured along the surface of the connecting member in the stretching direction is approximately the same as the shortest length from the end of the first substrate connected by the connecting member to the end of the second substrate when viewed from above, then when the first substrate is not stretched, the connecting member does not flex and can stably hold the first substrate and the second substrate.

[0078] In order for the connecting member 40 to be stretched in the same way as the first substrate 10 in the stretching direction, the Young's modulus of the connecting member 40 in the stretching direction is preferably less than 110% of the Young's modulus of the first substrate 10 in the stretching direction.

[0079] If the Young's modulus of the connecting component in the direction of expansion and contraction is less than 110% of the Young's modulus of the first substrate in the direction of expansion and contraction, then it can be said that the connecting component is easily deformed to be the same as or greater than that of the first substrate. Therefore, when the first substrate expands and contracts, the connecting component is easily deformed in the direction of expansion and contraction of the first substrate.

[0080] That is, in the telescopic mounting substrate of Embodiment 1 of the present invention, it is preferable that the Young's modulus of the telescopic direction of the connecting member is less than 110% of the Young's modulus of the telescopic direction of the first substrate, and the force applied to the part connecting the second substrate and the connecting member by the telescopic direction of the first substrate is mitigated by the telescopic direction of the connecting member.

[0081] In the telescopic mounting substrate of Embodiment 1 of the present invention, it is preferable that the material constituting the connecting member is the same as the material constituting the first substrate. Furthermore, the same material constituting the connecting member and the material constituting the first substrate means that the connecting substrate constituting the connecting member is the same as the telescopic substrate constituting the first substrate, and the connecting wiring constituting the connecting member is the same as the telescopic wiring constituting the first substrate.

[0082] Furthermore, when the materials constituting the connecting member and the first substrate are the same, the Young's modulus of the connecting member in the expansion and contraction direction is more than 90% and less than 110% of the Young's modulus of the first substrate in the expansion and contraction direction. If the Young's modulus of the connecting member in the expansion and contraction direction is approximately the same as that of the first substrate in the expansion and contraction direction, it is more difficult to produce a portion with a smaller expansion rate.

[0083] The materials constituting the connecting member are the same as those constituting the first substrate, but the Young's modulus in the stretching direction of the connecting member and the Young's modulus in the stretching direction of the first substrate are not completely consistent. For example, the wiring density of the connecting wire constituting the connecting member is different from the wiring density of the stretching wire constituting the first substrate.

[0084] In the telescopic mounting substrate of Embodiment 1 of the present invention, it is preferable that the connecting member is integrated with the first substrate. Furthermore, the integration of the connecting member and the first substrate means that not only the connecting substrate and the telescopic substrate constituting the connecting member are integrated, but also the connecting wiring and the telescopic wiring constituting the connecting member are integrated.

[0085] If the connecting component is integrated with the first substrate, the mechanical strength of the connection between the connecting component and the first substrate is improved. Furthermore, it reduces the likelihood of wire breakage at the connection between the flexible wiring and the connecting wiring.

[0086] In this specification, "integration" refers to a state in which two or more components cannot be returned to their separate state without being damaged. Examples of integration include cutting out a portion of an identical component to use as another component, or joining two components by thermoforming.

[0087] Furthermore, when a portion of the first substrate is cut out as a connecting member, the portion that can be moved to a position that does not overlap with the plane on which the first substrate is fixed is used as the connecting member when the first substrate is fixed on the plane.

[0088] In the telescopic mounting substrate of Embodiment 1 of the present invention, it is preferable that the direction in which the connecting component and the second substrate are arranged is consistent with the telescopic direction of the first substrate.

[0089] exist Figures 1-5In the telescopic mounting substrate 1 shown, the second substrate 20 and two connecting members 40 are arranged along the x-direction. The telescopic direction of the first substrate 10 is the x-direction. Therefore, it can be said that the orientation of the second substrate 20 and the connecting members 40 is consistent with the telescopic direction (x-direction) of the first substrate 10.

[0090] Furthermore, when determining the arrangement direction of the second substrate and the connecting component, the positions of the center of gravity of the second substrate and the center of gravity of the connecting component are compared, and the direction in which the center of gravity of the second substrate and the center of gravity of the connecting component are aligned is determined as the arrangement direction of the second substrate and the connecting component.

[0091] exist Figures 1-5 In the telescopic mounting substrate 1 shown, a portion of the first substrate 10 is used as the connecting member 40. Since a portion of the first substrate 10 is used as the connecting member 40, the connecting substrate 50 constituting the connecting member 40 is integrated with the telescopic substrate 11, and the connecting wiring 51 constituting the connecting member 40 is integrated with the telescopic wiring 13 disposed on the telescopic substrate 11. Therefore, in the telescopic mounting substrate 1, it can be said that the connecting member 40 and the first substrate 10 are integrated.

[0092] As a method of using a portion of the first substrate 10 as the connecting member 40, examples include methods such as bonding the desired portion after completely separating the portion that becomes the connecting member 40 from the first substrate 10, and retaining a portion of the boundary between the portion that becomes the connecting member 40 and the first substrate 10 without separating it. By retaining a portion of the boundary between the portion that becomes the connecting member 40 and the first substrate 10 without separating it, the portion that becomes the connecting member 40 and the boundary between the first substrate 10 become the connection portion between the first substrate 10 and the connecting member 40.

[0093] By cutting out a portion of the first substrate 10 as a connecting component 40, such as... Figure 2 As shown, voids 40a and voids 40b are formed in the first substrate 10.

[0094] As described above, when a portion of the first substrate 10 is used as a connecting member, the connecting member does not overlap with the first substrate when viewed from above. Therefore, in the telescopic mounting substrate of the present invention, it is preferable that the connecting member does not overlap with the first substrate when viewed from above.

[0095] The connecting substrate and the elastic substrate can also be different materials.

[0096] Alternatively, the connecting substrate can be composed of multiple components, and its structure and composition can vary depending on location. For example, a connecting substrate connected to a stretchable substrate made of thermoplastic polyurethane (TPU) can have three parts: a portion adjacent to the stretchable substrate, a portion adjacent to the connector, and a portion in between. In this case, the connecting substrate adjacent to the stretchable substrate may be made of TPU, the connecting substrate adjacent to the connector may be made of a different material than TPU (e.g., a rigid substrate), and in the middle portion, the connecting substrate may be a laminate of TPU and a rigid substrate.

[0097] In the telescopic mounting substrate of the present invention, it is preferable that the second substrate is physically connected to a plurality of connecting components.

[0098] exist Figures 1-5 In the telescopic mounting base plate 1 shown, the second base plate 20 is physically connected to a plurality of (two) connecting parts 40.

[0099] If the second substrate is physically connected to multiple connecting components, the force applied to the second substrate when the telescopic mounting substrate is deformed can be distributed among the multiple connecting components, thus reducing the change in the telescopic rate of the second substrate. Therefore, it is difficult to produce portions with a small telescopic rate in the telescopic mounting substrate.

[0100] The elastic substrate 11 is, for example, made of a resin material that is elastic. Examples of resin materials include thermoplastic polyurethane, silicone resin, acrylic resin, olefin resin, polyurethane resin, and elastic resin.

[0101] The thickness of the stretchable substrate 11 is not particularly limited, but from the viewpoint that it does not hinder the stretching and contraction of the surface of the organism when pasted onto it, it is preferably 100 μm or less, more preferably 1 μm or less. In addition, the thickness of the stretchable substrate 11 is preferably 0.1 μm or more.

[0102] The preferred flexible wiring comprises conductive particles and resin. For example, a mixture consisting of metal powders such as Ag, Cu, and Ni as conductive particles and elastic resins such as silicone-based resins can be cited.

[0103] The average particle size of the conductive particles is not particularly limited, but it is preferably 0.01 μm or more and 10 μm or less. In addition, it is preferred that the conductive particles are spherical.

[0104] The thickness of the flexible wiring is not particularly limited, but it is preferably 100 μm or less, more preferably 50 μm or less. Furthermore, the thickness of the flexible wiring is preferably 0.01 μm or more.

[0105] The line width for flexible wiring is not particularly limited, but it is preferably 0.1 μm or more, and more preferably 10 mm or less.

[0106] The Young's modulus of the first substrate in the stretching direction is preferably 0.001 GPa or higher and 1 GPa or lower.

[0107] The Young's modulus of the first substrate in the stretching direction can be determined by thermomechanical analysis (TMA).

[0108] Electrodes that come into contact with a living organism can also be formed on the other main surface of the first substrate, opposite to one main surface of the second substrate.

[0109] If electrodes are formed on the other main surface of the first substrate, biological data can be easily acquired as electrical signals.

[0110] Electronic components can also be mounted on the first substrate. However, for electronic components that can be mounted on the second substrate, it is preferable to mount them on the second substrate.

[0111] Examples of electronic components mounted on the first substrate include, for example, an accelerometer and a temperature sensor.

[0112] Electronic components mounted on the first substrate can also be covered with sealing resin or the like.

[0113] If the electronic components mounted on the first substrate are covered with a sealing resin or the like, it can prevent the degradation of the electronic components' characteristics caused by moisture intrusion.

[0114] The second substrate can be a rigid substrate made of epoxy glass substrate or the like, a flexible substrate, or a substrate with elasticity. As a substrate with elasticity, the elastic substrate constituting the first substrate can be used.

[0115] Even if the second substrate is a flexible substrate, if an inflexible object such as a control box is mounted on the surface of the second substrate as an electronic component, the flexibility of the second substrate may not be utilized. Even in such cases, if the second substrate is connected to the first substrate via a connecting member, it is difficult to produce a portion with a small rate of expansion.

[0116] The thickness of the rigid substrate is preferably 0.2 mm or more and 2 mm or less.

[0117] The thickness of the flexible substrate is preferably 0.01 mm or more and 1 mm or less.

[0118] The thickness of the substrate with elasticity is preferably 0.1 μm or more and 100 μm or less.

[0119] The second substrate can also be a multilayer substrate. Alternatively, wiring and electronic components can be disposed on both sides of the second substrate.

[0120] The top view area of ​​the second substrate is not particularly limited, but is preferably 1 cm. 2 Above and 400cm 2 the following.

[0121] If the top view area of ​​the second substrate is less than 1 cm² 2 If this is not the case, it may be difficult to install the required electronic components. On the other hand, if the top view area of ​​the second substrate exceeds 400 cm², it may also cause problems. 2 If the size of the second substrate is too large, the fit when worn on a living organism will be reduced.

[0122] Examples of electronic components mounted on the second substrate include amplifiers (operational amplifiers, transistors, etc.), surface-mount capacitors, surface-mount resistors, and microcomputers (MCUs). There are no particular limitations on the mounting configuration of these electronic components; they can be mounted as bare chips, ball grid arrays (BGAs), chip-scale packages (CSPs), surface-mount devices (SMDs), etc. Furthermore, multiple electronic components can be mounted.

[0123] Examples of materials that can be used to form the wiring disposed on the second substrate include copper, silver, tin, nickel, gold, and alloys of these materials. Furthermore, if the second substrate is a flexible substrate, it is preferable to use the same flexible wiring as that constituting the first substrate.

[0124] In the telescopic mounting substrate of the present invention, the second substrate preferably further includes a connecting connector, which is connected to the end of the wiring of the second substrate, and one end of the connecting wiring of the connecting component is electrically connected to the wiring of the second substrate by fitting with the connecting connector.

[0125] If the second substrate has a connector, it is possible to easily switch between the state of connecting the first substrate and the second substrate via the connecting member and the state of disconnection. Easy switching of the connection makes it easier to replace the second substrate while the first substrate is in contact with a living organism. Furthermore, it is easy to separate and discard the first substrate that is in contact with the living organism, while the second substrate that is not in contact with the living organism can be recycled and reused.

[0126] In the telescopic mounting substrate of the present invention, the preferred connecting connector is a flexible flat cable connector.

[0127] The height dimension of a flexible flat cable (FFC) connector is lower than that of a typical cable connector. This allows for a lower overall profile of the second substrate. Furthermore, because FCC connectors are more rigid than flexible substrates, they are less prone to breakage from impacts during assembly and disassembly, resulting in excellent durability.

[0128] In the telescopic mounting substrate of the present invention, it is preferable that the thickness of the connecting member is thinner than the mating thickness of the connecting connector, and an auxiliary material is disposed on a main surface in the thickness direction at one end of the connecting member to adjust the thickness of the connecting member to be approximately the same as the mating thickness of the connecting connector. However, the maximum thickness of the connecting member may also be thicker than the mating thickness of the connecting connector.

[0129] From the perspective of ensuring the deformability of the connecting component, the required thickness of the connecting component may be thinner than from the perspective of ensuring operability when connecting the connecting component to the connector. Even in this case, if the aforementioned auxiliary materials are provided, the deformability of the connecting component and the connection between the connecting component and the connector can be ensured.

[0130] The preferred auxiliary materials are epoxy glass substrates or flexible substrates.

[0131] Due to the high mechanical strength of auxiliary materials made of epoxy glass substrates or flexible substrates, they exhibit excellent durability under repeated connection conditions of components and connectors. Furthermore, the thickness and shape of auxiliary materials made of epoxy glass substrates or flexible substrates can be easily adjusted.

[0132] Figure 6 This is a perspective view schematically representing an example of the end of a connecting component. Figure 7 This is a perspective view schematically representing an example of a connecting connector.

[0133] like Figure 6 As shown, at the end of the connecting component 40, the connecting wire 51 is exposed on the connecting substrate 50.

[0134] An auxiliary material 60 for adjusting the thickness of the connecting member 40 is disposed on a main surface in the thickness direction at one end of the connecting member 40. The thickness of the connecting member 40 itself is measured by t. 11 The thickness indicated is expressed in tons (t). The thickness of the auxiliary material (60) is measured in tons (t). 12 The thickness is indicated by t. Therefore, the thickness of the end of the connecting part 40 is denoted by t. 11 and t 12 The total thickness t1 is used to represent this. If the thickness t1 at the end of the connecting component 40 and... Figure 7 If the thickness (fitting thickness) t2 of the mating portion 70a of the connector 70 shown is equal, then the connecting member 40 and the connector 70 can be mated. Furthermore, the shape of the connector is not limited to... Figure 7 The shape shown.

[0135] like Figure 6As shown, the auxiliary material 60 has an electrode 65 on its surface, and the connecting wiring 51 and the electrode 65 are electrically connected by a through conductor (not shown) that passes through the connecting substrate 50 and the auxiliary material 60 in the thickness direction.

[0136] Furthermore, a terminal electrically connected to the connecting wire 51 or the electrode 65 is provided within the mating portion 70a of the connector 70, but... Figure 7 The record is omitted.

[0137] In addition, Figure 6 In the connector 70 shown, electrodes 65 are provided on the surface of the auxiliary material 60, but electrodes may not be formed on the surface of the auxiliary material. In this case, the auxiliary material functions as a material that mechanically reinforces the connecting parts.

[0138] exist Figures 1-5 In the telescopic mounting substrate shown, the connector 70 is configured such that the mating portion opens in the horizontal direction (x direction), but the direction of the opening of the mating portion of the connector is not limited to the horizontal direction. Therefore, the direction of the opening of the mating portion of the connecting member can also be a direction orthogonal to the surfaces extending from the first substrate 10 and the second substrate 20 (z direction).

[0139] Although Figure 7 Although not shown in the figure, a locking mechanism can also be provided on the connector to fix the connecting parts in a state of engagement with the connector.

[0140] The telescopic mounting substrate of the present invention can be worn by attaching the first substrate to a living organism, or by wrapping the first substrate around the arm, wrist, neck, torso, leg, etc. Adhesive tape or similar materials can also be used when attaching the telescopic mounting substrate of the present invention to a living organism.

[0141] (Implementation Method 2)

[0142] Figure 8 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 2 of the present invention. Figure 9 yes Figure 8 Side view of the middle. Figure 10 It is a schematic representation in Figure 9 A diagram showing an example of a deformed connecting component.

[0143] Figure 8 The telescopic mounting base plate 2 shown is modified. Figures 1-4 The substrate following the structure of the connecting member 40 in the telescopic mounting substrate 1 shown. Specifically, in Figure 8 In the telescopic mounting base plate 2 shown, the connecting member 42 that connects the first base plate 10 and the second base plate 20 has a corrugated shape.

[0144] The boundary between the first substrate 10 and the connecting member 42 is marked by a dashed line e. 31 The positions indicated by the dashed line e represent the boundaries between the connecting part 42 and the connecting connector 70. 32 The position is indicated. Therefore, the length of the connecting part 42 when viewed from above is indicated by a double-headed arrow d3.

[0145] like Figure 9 As shown, in the unstretched state of the first substrate 10, the length of the connecting member 42 along the stretching direction (x direction) measured along the surface of the connecting member 42 (in... Figure 9 In the diagram, the length l3 (represented by a thick line) is greater than the length from the end of the first substrate 10 connected by the connecting member 42 (represented by a dashed line e) when viewed from above on the telescopic mounting substrate 2. 31 The position indicated is from the end of the second substrate 20 (marked by dashed line e). 32 The shortest length of the position (in) Figure 9 In the middle, the length indicated by the double-headed arrow d3 is long, and the connecting part 42 flexes in the x direction.

[0146] Furthermore, the deflection is expressed as the difference between the shortest length d3 from the end of the first substrate connected by the connecting member in the telescoping direction to the end of the second substrate and the length l3 of the connecting member in the telescoping direction as measured along the surface of the connecting member.

[0147] In the unstretched state of the first substrate, the flexed portion of the connecting member is also referred to as the flexed portion. That is, the connecting member may also have a flexed portion. Furthermore, the first substrate may also have a flexed portion in the stretched state.

[0148] like Figure 10 As shown, when the first substrate 10 expands and contracts along the x-direction, the corrugated shape of the connecting member 42 is stretched. At this time, when viewing the telescopically mounted substrate 2 from above, the end of the first substrate 10 connected by the connecting member 42 (marked with a dashed line e)... 31 The position indicated is from the end of the second substrate 20 (marked by dashed line e). 32 The shortest length of the position (in) Figure 10 In the middle, the length shown by the double-headed arrow d4 is greater than... Figure 9 The length of the connecting member 42 changes due to its extension. The length of the connecting member 42 along the extension / retraction direction (x-direction), measured along its surface, is... Figure 9 and Figure 10 The same as in the middle. That is, along... Figure 10 The length of the connecting member 42 in the telescopic direction (x direction) measured from the surface of the connecting member 42 shown (in... Figure 10 In the diagram, the length l4 is represented by a thick line and... Figure 9 The length l3 shown is the same.

[0149] according to Figure 9 as well as Figure 10 In the telescopic mounting substrate 2, it can be said that the force applied to the part connecting the second substrate 20 and the connecting member 42 by the telescopic direction (x direction) of the first substrate 10 is mitigated by the change in the deflection of the connecting member 42.

[0150] (Implementation Method 3)

[0151] Figure 11 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 3 of the present invention. Figure 12 yes Figure 11 Side view of the middle.

[0152] like Figure 11 as well as Figure 12 As shown, the boundary between the first substrate 10 and the connecting member 44 is indicated by a dashed line e. 51 The positions indicated by the dashed line e represent the boundaries between the connecting part 44 and the connecting connector 70. 52 The indicated location.

[0153] In the unstretched state of the first substrate 10, the length of the connecting member 44 along the stretching direction (x direction) measured along the surface of the connecting member 44 (in... Figure 12 In the diagram, the length l5 (represented by a thick line) is greater than the length of the first substrate 10 connected by the connecting member 44 (represented by a dashed line) when viewed from above as the telescopic mounting substrate 3. 51 The position indicated is from the end of the second substrate 20 (marked by dashed line e). 52 The shortest length of the position (in) Figure 12 In the middle, the length indicated by the double-headed arrow d5) is long, and the connecting part 44 is flexed.

[0154] Therefore, in the telescopic mounting substrate 3, the force applied to the portion connecting the second substrate 20 and the connecting member 44 by the telescopic direction (x direction) of the first substrate 10 is mitigated by the change in the deflection of the connecting member 44.

[0155] like Figure 8 , Figure 9 , Figure 10 , Figure 11As shown in Figure 12, in the telescopic mounting substrates of Embodiments 2 and 3 of the present invention, preferably, when the first substrate is not telescopic, the length of the connecting member in the telescopic direction, measured along the surface of the connecting member, is longer than the shortest length from the end of the first substrate connected by the connecting member to the end of the second substrate when the telescopic mounting substrate is viewed from above. The connecting member flexes, and the force applied to the portion connecting the second substrate and the connecting member by the telescopic movement of the first substrate is mitigated due to the change in the amount of deflection of the connecting member. In this case, the Young's modulus of the connecting member in the telescopic direction can also be greater than 110% of the Young's modulus of the first substrate in the telescopic direction. Furthermore, in this case, it is preferable that the connecting member is made of a flexible substrate.

[0156] (Implementation Method 4)

[0157] Figure 13 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 4 of the present invention. Figure 14 yes Figure 13 Side view of the middle.

[0158] Figure 13 and Figure 14 The telescopic mounting base plate 4 shown has a plurality of first base plates 10a, 10b.

[0159] The first substrate 10a and the first substrate 10b are respectively connected to the second substrate 20 via the connecting member 40.

[0160] The boundary between the first substrate 10a and the connecting member 40 is marked by a dashed line e. 71 The positions indicated by the dashed line e represent the boundaries between the connecting part 40 and the connecting connector 70. 72 The position is indicated. Therefore, the length of the connecting part 40 when viewed from above is indicated by a double-headed arrow d7.

[0161] That is, such as Figure 13 and Figure 14 As shown, in the telescopic mounting substrate of Embodiment 4 of the present invention, it is preferable to have a plurality of first substrates, each of which is connected to a second substrate via a connecting member. Since the first substrates are divided into a plurality of units, the stress during telescopic movement can be dispersed among the divided plurality of first substrates, thus alleviating the stress applied to a single first substrate.

[0162] In the case where a plurality of first substrates are provided, such as the telescopic mounting substrate of Embodiment 4 of the present invention, there may be a situation where a region of the first substrate that overlaps with the second substrate when viewed from above spans the plurality of first substrates. In such a case, after determining the telescopic rate of that region of all the first substrates having a region that overlaps with the second substrate when viewed from above, the sum of the telescopic rates obtained by multiplying the area ratio of that region (the area of ​​that region / the total area of ​​the first substrate and the second substrate overlapping when viewed from above) as a contribution rate is compared with the telescopic rate of the second substrate.

[0163] When multiple first substrates are provided, it is preferable that each first substrate is fixed to the second substrate at at least one location using an adhesive or the like. There are no particular limitations on the location where each first substrate is fixed to the second substrate, but it is preferable that it is fixed to the second substrate at the location furthest from the boundary of the connecting member. Furthermore, when two first substrates are provided, only one of the first substrates may be fixed to the second substrate using an adhesive or the like, or neither of the first substrates may be fixed to the second substrate.

[0164] Figure 15 This is a side view schematically illustrating a modified example of the telescopic mounting substrate according to Embodiment 4 of the present invention.

[0165] Figure 15 The telescopic mounting base plate 104 shown includes: a first base plate 10, a second base plate 20, and a connecting member 40 that physically connects the first base plate 10 and the second base plate 20.

[0166] The boundary between the first substrate 10 and the connecting member 40 is marked by a dashed line e. 71 The positions indicated by the dashed line e represent the boundaries between the connecting part 40 and the connecting connector 70. 72 The position is indicated. Therefore, the length of the connecting part 40 is indicated by the double-headed arrow d7.

[0167] The first substrate 10 is annular, with one end and the other end in contact with the second substrate 20.

[0168] exist Figure 15 In the telescopic mounting base plate 104 shown, since the first base plate 10 is ring-shaped, the telescopic mounting base plate 104 can be fixed to the human body by wrapping the first base plate 10 around the human body.

[0169] The position of the rollable mounting base 104 is not particularly limited; for example, it can be used for arms, wrists, necks, torsos, legs, etc. The length of the first base plate 10 can be adjusted appropriately according to the desired position of the human body.

[0170] Furthermore, the first substrate 10 can also be joined to each other directly below the second substrate 20. In this case, the telescopic mounting substrate can be considered as constituting... Figures 1-5The two ends of the first substrate 10 of the telescopic mounting substrate 1 shown are connected in a ring shape.

[0171] (Implementation Method 4)

[0172] Figure 16 This is a perspective view schematically illustrating an example of further deformation of the telescopic mounting substrate of Embodiment 4 of the present invention. Figure 17 yes Figure 16 Side view of the middle.

[0173] Figure 16 The telescopic mounting base plate 5 shown includes: a second base plate 20 and connecting members 45 whose two ends are physically connected to connecting connectors 70 disposed on the second base plate 20. The connecting members 45 include a connecting substrate 50 and connecting wiring 51. Figure 17 As shown, the boundary between the connecting part 45 and the connecting connector 70 is indicated by a dashed line e. 82 The indicated position. That is, Figure 16 and Figure 17 The telescopic mounting base plate 5 shown can be said to be in Figure 13 and Figure 14 The telescopic mounting substrate 4 shown only retains the portion of the first substrate 10 that serves as the connecting member 40.

[0174] In the telescopic mounting base of embodiment 4', the telescopic mounting base can be fixed to the human body by wrapping the connecting member around the human body. The position where the telescopic mounting base 5 is wrapped is not particularly limited; for example, an arm, wrist, neck, torso, or leg can be extended. The length of the connecting member 45 can be appropriately adjusted according to the desired position of the human body.

[0175] (Implementation Method 5)

[0176] Figure 18 This is a side view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 5 of the present invention.

[0177] like Figure 18 As shown, in the telescopic mounting substrate 101, an insulating protective layer 90 is provided between the first substrate 10 and the second substrate 20. The protective layer 90 extends from the end of another main surface 20b of the second substrate 20 along the lower surface of the connecting member 40.

[0178] If the protective layer 90 extends from the end of the other main surface 20b of the second substrate 20 along the lower surface of the connecting member 40, it can prevent the second substrate 20 from contacting the wearer through the gaps 40a and 40b provided in the first substrate 10.

[0179] like Figure 18As shown, in the telescopic mounting substrate of Embodiment 5 of the present invention, it is preferable that the electronic component is mounted on only one main surface of the second substrate, and an insulating protective layer is provided on the side of the second substrate on which the electronic component is not mounted, i.e., the other main surface. The protective layer extends from the end of the other main surface of the second substrate along the lower surface of the connecting member, and when viewed from above, at least a portion of the lower surface of the connecting member overlaps with the protective layer.

[0180] The length of the protective layer extending along the lower surface of the connecting member from the end of the other main surface of the second substrate is not particularly limited, but when the telescopic mounting substrate is viewed from the thickness direction, it is preferable that the entire second substrate overlaps with the protective layer.

[0181] As materials constituting the protective layer, in addition to the same materials as the elastic substrate constituting the first substrate, materials that are biocompatible, such as polyurethane, sponge, rubber, and cotton, can also be used.

[0182] If the material constituting the protective layer is the same as the material constituting the elastic substrate, the discomfort during wearing can be reduced.

[0183] (Implementation Method 6)

[0184] Figure 19 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 6 of the present invention. Figure 20 yes Figure 19 Side view of the middle.

[0185] Figure 19 and Figure 20 The telescopic mounting base plate 6 shown includes a first base plate 10, a second base plate 20, and a connecting member 46 that physically connects the first base plate 10 and the second base plate 20.

[0186] When viewed from the side, the connecting member 46 has an arched shape that extends over the second substrate 20 in the x-direction. The central portion of the connecting member 46 in the x-direction engages with the connecting connector 72 disposed on the electronic component 30. (Used with dashed line e) 91 The indicated position is the boundary between the first substrate 10 and the connecting member 46.

[0187] The end of the connecting member 46 on the second substrate 20 side branches in a T-shape from approximately the center of the arched shape and protrudes downward (on the second substrate 20 side) to engage with the connecting connector 72. Therefore, indicated by the dashed line e... 92 The indicated position is the boundary between connecting part 46 and connecting connector 72. Therefore, connecting part 46 can be said to be formed by the boundary line e. 91 The position shown extends to the dashed line e. 92 It consists of two connecting parts, which are shown in the position and have a length of double-headed arrow d9 when viewed from above.

[0188] At this time, the mating portion provided in the connector 72 opens on the main surface opposite to the surface of the connector 72 that contacts the electronic component 30. Therefore, the mating portion can also be described as opening upwards (in the z direction).

[0189] Although not shown, the connecting member 46 includes a connecting substrate and connecting wiring. Therefore, by engaging one end of the connecting member with the connecting connector 72, the telescopic wiring of the first substrate 10 and the wiring of the second substrate 20 are electrically connected via the connecting wiring.

[0190] Furthermore, wiring that does not directly contact the second substrate 20, such as wiring disposed on the surface of an object mounted on the second substrate 20, and wiring disposed on the surface of an electronic component 30, are also included in the wiring disposed on the second substrate 20.

[0191] (Implementation Method 7)

[0192] Figure 21 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 7 of the present invention. Figure 22 yes Figure 21 Sectional view along line AA in the diagram.

[0193] Figure 21 and Figure 22 The telescopic mounting base 105 shown includes a first base plate 15, a second base plate 25, and a connecting member 47 that physically connects the first base plate 15 and the second base plate 25.

[0194] like Figure 22 As shown, the connecting member 47 flexes in the x direction and has a flexed portion.

[0195] Therefore, in the telescopic mounting substrate 105, the force applied to the portion connecting the second substrate 25 and the connecting member 47 by the telescopic movement of the first substrate 15 in the x direction is mitigated by the change in the deflection of the connecting member 47.

[0196] In the telescopic mounting substrate of Embodiment 7 of the present invention, the material constituting the connecting member may be the same as the material constituting the second substrate.

[0197] Furthermore, the fact that the material constituting the connecting component is the same as the material constituting the second substrate means that the connecting substrate constituting the connecting component is the same as the second substrate, and the connecting wiring constituting the connecting component is the same as the wiring provided on the second substrate.

[0198] exist Figure 21 and Figure 22 In the telescopic mounting substrate 105 shown, the connecting substrate 50 constituting the connecting member 47 is made of the same material as the second substrate 25.

[0199] In addition, the connecting wires 51 constituting the connecting member 47 are made of the same material as the wires 35 provided on the second substrate 25.

[0200] That is, the material constituting the connecting member 47 is the same as the material constituting the second substrate 25.

[0201] A coil component 32, which is composed of a coil conductor 31, is formed on the second substrate 25.

[0202] The coil conductor 31 is part of the wiring 35 disposed on the second substrate 25.

[0203] The coil component 32 and the connecting wire 51 constituting the connecting component 47 are connected by the wire 35 provided on the second substrate 25.

[0204] Furthermore, the end of the coil component 32 that is not connected to the wiring 35 can be connected to an electronic component disposed on the second substrate, or it can be connected to other wiring (not shown) disposed on the outside of the coil conductor 31 disposed on the second substrate in a state of being insulated from the coil conductor 31 by cross wiring and conductive conductor.

[0205] The coil conductor can be formed on only one surface of the second substrate, or it can be formed on both surfaces. When coil conductors are formed on both surfaces of the second substrate, the two coil conductors can also be connected by a conductive conductor that penetrates the second substrate in the thickness direction. Therefore, for example, in Figure 21 and Figure 22 In the telescopic mounting substrate 105 shown, the end of the coil component 32 that is not connected to the wiring 35 can also be connected to the coil component disposed on the surface of the opposite side (first substrate side) of the second substrate via a conductive conductor.

[0206] Electronic components such as coil components disposed on the surface of the second substrate on the side of the first substrate can also be electrically connected to the first substrate via connecting wiring disposed on the surface of the connecting component on the side of the first substrate.

[0207] The connecting wiring 51, wiring 35 and coil conductor 31 are integrally formed.

[0208] In the telescopic mounting substrate 105, a coil component 32, which is an electronic component, is mounted on the second substrate 25. However, the electronic component mounted on the second substrate is not limited to the coil component.

[0209] In the telescopic mounting substrate of Embodiment 7 of the present invention, the connecting member and the second substrate may also be integrated. Furthermore, the so-called integration of the connecting member and the second substrate means that not only is the connecting substrate constituting the connecting member integrated with the second substrate, but also the connecting wiring constituting the connecting member and the wiring disposed on the second substrate are integrated.

[0210] exist Figure 21 In the telescopic mounting substrate 105 shown, the connecting substrate 50 constituting the connecting member 47 and the second substrate 25 are integrated.

[0211] In addition, the connecting wiring 51 constituting the connecting member 47 and the wiring 35 provided on the second substrate 25 are integrated.

[0212] Furthermore, when the connecting wire 51 constituting the connecting member 47 and the wiring 35 provided on the second substrate 25 are integrated, there is no need for a connecting connector that electrically connects the connecting wire 51 and the wiring 35.

[0213] In the telescopic mounting substrate of Embodiment 7 of the present invention, a sliding film may also be disposed between the first substrate and the second substrate.

[0214] exist Figure 22 In the telescopic mounting substrate 105 shown, a sliding membrane 34 is provided between the first substrate 15 and the second substrate 25.

[0215] As a material constituting the sliding film 34, examples include resin films on which a treatment has been applied to the surface to reduce the coefficient of friction, such as a fluorine coating.

[0216] Preferably, the coefficient of friction generated between the sliding film and the second substrate is smaller than the coefficient of friction generated between the first substrate and the second substrate.

[0217] (Implementation Method 8)

[0218] Figure 23 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 8 of the present invention. Figure 24 yes Figure 23 BB line section view. Figure 25 yes Figure 23 The CC line section view.

[0219] Figure 23 , Figure 24 as well as Figure 25 The telescopic mounting base 107 shown includes a first base plate 15, a second base plate 25, and a connecting member 48 that physically connects the first base plate 15 and the second base plate 25.

[0220] In the telescopic mounting substrate of Embodiment 8 of the present invention, the connecting member may also have two or more flexural portions with different telescopic directions.

[0221] like Figure 23 , Figure 24 as well as Figure 25As shown, the connecting member 48 has a first flexural portion 48x that flexes in the x direction and a second flexural portion 48y that flexes in the y direction.

[0222] If the connecting member 48 has two or more flexural portions with different flexural directions, then when the first substrate 15 is stretched or contracted in any direction, the deformation of the first substrate in the x and y directions can be suppressed by changing the amount of flexure through both the first flexural portion 48x and the second flexural portion 48y.

[0223] Furthermore, the deflection directions of the first and second deflections only need not be parallel to each other. Therefore, the deflection directions of the first and second deflections can be orthogonal or non-orthogonal.

[0224] Furthermore, the connecting component having two or more flexural portions with different flexural directions as described above is not limited to embodiment 8, and can also be used in other embodiments.

[0225] Alternatively, a portion (hereinafter also referred to as the intermediate portion) that connects the substrate without bending in any direction can be provided between the first flexed portion and the second flexed portion.

[0226] like Figure 24 and Figure 25 As shown, the intermediate portion 48z of the connecting member 48, disposed between the first flexural portion 48x and the second flexural portion 48y, does not contact the first substrate 15. However, even when the intermediate portion 48z is not bonded to the first substrate 15, it can still contact the first substrate 15.

[0227] (Implementation Method 9)

[0228] Figure 26 This is a top view schematically illustrating an example of a telescopic mounting substrate according to the ninth embodiment of the present invention. Figure 27 yes Figure 26 DD line section view.

[0229] like Figure 26 and Figure 27 As shown, the telescopic mounting base plate 109 includes: a first base plate 15, a second base plate 25, a connecting member 48 connecting the first base plate 15 and the second base plate 25, and a third base plate 33.

[0230] The connecting member 48 is the same as the connecting member described in the telescopic mounting substrate of the eighth embodiment. Therefore, the connecting member 48 has a first flexural portion, a second flexural portion, and an intermediate portion.

[0231] In the stretchable mounting substrate of the ninth embodiment of the present invention, a third substrate made of a stretchable substrate may also be provided on the surface of the second substrate.

[0232] like Figure 26 and Figure 27 As shown, in the telescopic mounting substrate 109, a third substrate 33 made of a telescopic substrate is provided on the surface of the second substrate 25.

[0233] Magnetic materials may also be included in the stretchable substrate constituting the third substrate. If the stretchable substrate constituting the third substrate includes magnetic materials, the characteristics of the coil component can be improved when the coil component is mounted on the surface of the second substrate. Furthermore, the third substrate 33 is not limited to a substrate that mounts the component.

[0234] (Implementation Method 10)

[0235] Figure 28 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 10 of the present invention. Figure 29 yes Figure 28 Side sectional view.

[0236] like Figure 28 and Figure 29 As shown, in the telescopic mounting substrate 7, the electronic component 30 mounted on the second substrate 20 is covered by a rigid portion 80. By covering the electronic component 30 with the rigid portion 80, contact between the electronic component 30 and moisture can be prevented, improving water resistance and moisture resistance. Figure 28 As shown, when viewed from above, the rigid part 80 does not overlap with the connecting part 40.

[0237] Figure 30 This is a top view schematically illustrating another example of the telescopic mounting substrate of Embodiment 10 of the present invention. Figure 31 yes Figure 30 Side sectional view.

[0238] like Figure 30 and Figure 31 As shown, in the telescopic mounting substrate 8, the electronic component 30 mounted on the second substrate 20 is covered by a sealing resin 83. Since covering the electronic component 30 with the sealing resin 83 isolates it from moisture, it is equivalent to using… Figure 28 and Figure 29 The rigid portion 80 of the telescopic mounting base plate 7 is described.

[0239] like Figure 28 and Figure 29 as well as Figure 30 and Figure 31 As shown, in the telescopic mounting substrate of Embodiment 7 of the present invention, it is preferable that the surface of the second substrate has a rigid portion that covers at least a portion of the electronic components and isolates them from moisture.

[0240] exist Figure 28 and Figure 29 In this invention, the connector 70 disposed on the second substrate 20 is not covered by the rigid portion 80. However, in the telescopic mounting substrate of the present invention, the rigid portion 80 may cover structures other than the electronic component 30 disposed on the second substrate 20, such as the connector 70.

[0241] Alternatively, for example, the top view shape of the rigid portion 80 may be approximately the same as the top view shape of the second substrate 20, or the entire surface of the second substrate 20 on which the electronic component 30 is mounted may be covered by the rigid portion.

[0242] exist Figure 30 as well as Figure 31 In this invention, the connector 70 disposed on the second substrate 20 is not covered by the sealing resin 83.

[0245] Figure 32 This is a top view schematically illustrating an example of a telescopic mounting substrate according to Embodiment 11 of the present invention. Figure 33 yes Figure 32 Side sectional view. Figure 34 It is a schematic representation in Figure 32 as well as Figure 33 A perspective view of an example of a waterproof housing used.

[0246] like Figure 32 As shown, in the telescopic mounting base plate 9, the second base plate 20 is entirely housed within the waterproof housing 85. (As indicated...) Figure 34 As shown, the waterproof housing 85 is composed of an openable and closable bottom 85a and a cover 85b, and has a receiving portion for accommodating a second substrate.

[0247] Sealing portions 88a and 88b extending along a portion of the contact surface are provided at the contact surface between the bottom 85a of the waterproof housing 85 and the cover 85b.

[0248] like Figure 33 As shown, with the waterproof housing 85 closed, the connecting member 40 is held in place by the sealing portions 88a and 88b. By having the connecting member 40 held in place by the sealing portions 88a and 88b, moisture can be prevented from entering the interior of the waterproof housing 85.

[0249] Therefore, in the telescopic mounting substrate of Embodiment 11 of the present invention, it is preferable that the telescopic mounting substrate also includes a waterproof housing, which is composed of an openable and closable bottom and a cover, and has a receiving portion that can accommodate a second substrate. The second substrate is entirely accommodated in the receiving portion, and a sealing portion extending along at least a portion of the contact surface between the bottom and the cover is provided. When the waterproof housing is closed, the connecting member is clamped by the sealing portion.

[0250] In the telescopic mounting substrate of Embodiment 11 of the present invention, a sealing portion may also be formed on the entire surface of the contact surface with the bottom and the cover.

[0251] In the telescopic mounting base plate of Embodiment 11 of the present invention, it is preferable to provide a linkage mechanism in the receiving portion of the waterproof housing, which is used to link the closing / opening of the waterproof housing and the engagement / disengagement of the connector and connecting parts.

[0252] As an example of a linkage mechanism, a fixing part provided on the cover of a waterproof housing, with the end of the connecting member fixed towards the bottom, can be cited. A second base plate containing a connecting connector with an upper opening for a mating portion is housed within the waterproof housing having this fixing part. The position of the connecting connector is adjusted so that when the waterproof housing is closed, the end of the connecting member is in the position of the mating portion of the connecting connector. By performing the position adjustment as described above, the connecting member engages with the mating portion of the connecting connector by closing the waterproof housing. Furthermore, by opening the waterproof housing, the end of the connecting member fixed by the fixing part moves away from the connecting connector, thereby releasing the engagement state between the connecting member and the connecting connector.

[0253] The telescopic mounting substrate of the present invention can be manufactured, for example, by connecting a first substrate and a second substrate using a connecting member. In this case, a portion of the first substrate can also be cut out and used as the connecting member.
