[Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2020-18783 A Summary of the Invention [Problem to be solved by the invention]
[0005] However, since the biological information is transmitted to the external device via the cable 8, the resistance value in the transmission path increases by the amount of the cable 8 used, and there is a risk that the accuracy of the transmitted biological information may decrease. It is also possible to connect a connector (not shown) to the cable 8 and transmit the biometric information to a measuring device, a communication device, etc. via the connector. However, even in this case, it is impossible to avoid an increase in resistance value due to the use of the cable 8. Furthermore, connecting a connector to the electrode unit shown in FIG. 30 causes a problem in that the device mounted on the garment 2 for acquiring the biometric information becomes larger.

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. First embodiment 1 and 2 show a connector 11 for acquiring biometric information according to embodiment 1. The connector 11 for acquiring biometric information is used, for example, as a clothing-side connector for fitting a wearable device, and is mounted on fabric 21 of the clothing to which it is to be mounted.
[0019] The connector 11 for acquiring biological information has a housing 12 made of an insulating material. The housing 12 holds two plug contacts PC so as to protrude perpendicularly from the substrate 21. The housing 12 has a top insulator 13 arranged on a front surface 21A of the fabric 21 and a bottom insulator 14 arranged on a back surface 21B of the fabric 21. The front surface 21A of the fabric 21 is the surface facing the outside of the garment and faces away from the user's body surface when the user wears the garment, while the back surface 21B of the fabric 21 is the surface facing the inside of the garment and faces the user's body surface when the user wears the garment.
[0020] 1, the top insulator 13 is disposed on the surface 21A of the substrate 21 via the reinforcing sheet 15, and has a recess 13A that opens in the opposite direction to the substrate 21. The bottom surface of the recess 13A forms a planar first exposed surface S1 that is exposed on the surface 21A side of the substrate 21, and the two plug contacts PC each protrude perpendicularly to the first exposed surface S1.
[0021] 2, the bottom insulator 14 is disposed directly on the back surface 21B of the substrate 21, and has a planar second exposed surface S2 exposed on the back surface 21B side of the substrate 21, and two electrode surfaces ES are disposed and exposed on the second exposed surface S2. The two electrode surfaces ES are disposed at positions corresponding to two plug contacts PC.
[0022] For convenience, the first exposed surface S1 and the second exposed surface S2 extend along the XY plane, the arrangement direction of the two plug contacts PC is called the Y direction, and the direction in which the two plug contacts PC protrude is called the +Z direction. The first exposed surface S1 of the top insulator 13 is exposed in the +Z direction, and the second exposed surface S2 of the bottom insulator 14 is exposed in the -Z direction. The Z direction is the mating direction in which the bioinformation acquisition connector 11 is mated with a mating connector (not shown). The two electrode surfaces ES are exposed in a state of protruding from the second exposed surface S2 of the bottom insulator 14 in the -Z direction.
[0023] 3 and 4 show assembly diagrams of the bioinformation acquisition connector 11. A reinforcing sheet 15 is disposed on the -Z direction side of the top insulator 13, and a fabric 21 is disposed on the -Z direction side of the reinforcing sheet 15. Furthermore, two conductive members 16 are disposed on the -Z direction side of the fabric 21, and a bottom insulator 14 is disposed on the -Z direction sides of the two conductive members 16. The conductive member 16 forms both the plug contact PC protruding in the +Z direction from the first exposed surface S1 and the electrode surface ES exposed in the -Z direction from the second exposed surface S2.
[0024] 5, two contact through holes 13B are formed in the recess 13A of the top insulator 13, each penetrating the top insulator 13 in the Z direction. The recess 13A constitutes a mating connector accommodating portion that accommodates a part of a mating connector (not shown), and the two contact through holes 13B correspond to two plug contacts PC. 6, a recessed step portion 13C is formed around the two contact through holes 13B on the peripheral edge of the surface facing the -Z direction of the top insulator 13. The step portion 13C has a depth substantially equal to the thickness dimension of the reinforcing sheet 15. Furthermore, the step portion 13C has four bosses 13D each protruding in the -Z direction.
[0025] 7, the bottom insulator 14 has a flat plate portion 14A, in which two electrode through holes 14B are formed, each of which penetrates the flat plate portion 14A in the Z direction. The two electrode through holes 14B are disposed at positions corresponding to the two contact through holes 13B of the top insulator 13. Further, in the flat plate portion 14A, four boss through holes 14C are formed which correspond to the plurality of bosses 13D of the top insulator 13 and penetrate the flat plate portion 14A in the Z direction.
[0026] 8, the surface of the bottom insulator 14 that forms the second exposed surface S2 facing the -Z direction has recesses 14D formed therein to surround the boss through-holes 14C. The recesses 14D are intended to accommodate the tips of the bosses 13D of the top insulator 13 that have been thermally deformed through the boss through-holes 14C when the bioinformation acquisition connector 11 is assembled.
[0027] 9 and 10, the conductive member 16 is a solid member made of a conductive material such as a metal, and has a substantially cylindrical contact portion 16A extending in the Z direction along the fitting axis C, a substantially cylindrical electrode portion 16B adjacent to the -Z direction side of the contact portion 16A and extending in the Z direction along the fitting axis C, and a brim-shaped flange portion 16C protruding along the XY plane from the boundary between the contact portion 16A and the electrode portion 16B. Such a conductive member 16 can be produced by, for example, pressing or cold rolling. The fitting axis C passes through the center of the conductive member 16 and extends in the fitting direction of the biometric information acquisition connector 11 and the mating connector.
[0028] 5 has an inner diameter that is slightly larger than the maximum diameter D1 of the contact portion 16A of the conductive member 16 and smaller than the diameter D3 of the flange portion 16C. In addition, the length L1 in the Z direction of the contact portion 16A of the conductive member 16 is set to be longer than the thickness in the Z direction of the bottom portion of the recess 13A of the top insulator 13.
[0029] 7 has an inner diameter that is slightly larger than the diameter D2 of the electrode portion 16B of the conductive member 16 and smaller than the diameter D3 of the flange portion 16C. The electrode portion 16B of the conductive member 16 includes a cylindrical portion extending in the Z direction by a length L2 along the fitting axis C and a bulging portion bulging in the -Z direction from the cylindrical portion, and a convex electrode surface ES is formed by the surface of the bulging portion. The length L2 of the cylindrical portion in the Z direction is set to be approximately equal to the thickness of the flat portion 14A of the bottom insulator 14 in the Z direction. Furthermore, the flange portion 16C of the conductive member 16 has a thickness in the Z direction that is approximately equal to the thickness of the material 21.
[0030] 11, the reinforcing sheet 15 is for reinforcing the fabric 21 of the clothing on which the biometric information acquisition connector 11 is mounted, is made of an insulating material, and has an opening 15A formed in the center. Furthermore, along the periphery of the opening 15A of the reinforcing sheet 15, four notches 15B corresponding to the four bosses 13D of the top insulator 13 are formed.
[0031] As shown in FIG. 12, the fabric 21 of the garment has two through holes 21C corresponding to the two conductive members 16, and four through holes 21D arranged around the two through holes 21C and corresponding to the four bosses 13D of the top insulator 13. The through hole 21C of the substrate 21 has a diameter that is substantially equal to the diameter D3 of the flange portion 16C of the conductive member 16, or is slightly larger than the diameter D3.
[0032] The two contact through holes 13B of the top insulator 13, the two through holes 21C of the fabric 21, the two conductive members 16, and the two electrode through holes 14B of the bottom insulator 14 are positioned to be aligned with each other in the Z direction. In addition, the four bosses 13D of the top insulator 13, the four cutouts 15B of the reinforcing sheet 15, the four through holes 21D of the fabric 21, and the four boss through holes 14C of the bottom insulator 14 are aligned with each other in the Z direction.
[0033] When assembling the bioinformation acquisition connector 11, first, the reinforcing sheet 15 and the fabric 21 are sequentially arranged on the surface facing the -Z direction of the top insulator 13 so that the four bosses 13D of the top insulator 13 penetrate the four notches 15B of the reinforcing sheet 15 and the four through holes 21D of the fabric 21. At this time, the peripheral portion of the opening 15A of the reinforcing sheet 15 is accommodated in the step portion 13C of the top insulator 13, and the two through holes 21C of the fabric 21 are positioned on the -Z direction side of the two contact through holes 13B of the top insulator 13 through the opening 15A of the reinforcing sheet 15.
[0034] Furthermore, the contact portions 16A of the two conductive members 16 are inserted from the -Z direction into the two through holes 21C of the substrate 21 and the two through holes for contact 13B of the top insulator 13. Here, the through holes for contact 13B of the top insulator 13 have an inner diameter slightly larger than the diameter D1 of the contact portions 16A of the conductive members 16 and smaller than the diameter D3 of the flange portions 16C, and the through holes 21C of the substrate 21 have a diameter approximately equal to the diameter D3 of the flange portions 16C of the conductive members 16 or slightly larger than the diameter D3.
[0035] Therefore, when the contact portion 16A of the conductive member 16 is inserted into the through hole 21C of the fabric 21 and the contact through hole 13B of the top insulator 13, the flange portion 16C of the conductive member 16 abuts against the surface facing the -Z direction of the top insulator 13 around the contact through hole 13B. In this state, while the electrode portions 16B of the two conductive members 16 are inserted into the two electrode through holes 14B of the bottom insulator 14, the bottom insulator 14 is placed on the surface of the fabric 21 facing the -Z direction from the -Z direction and pressed in the +Z direction toward the top insulator 13.
[0036] Furthermore, the electrode through hole 14B of the bottom insulator 14 has an inner diameter slightly larger than the diameter D2 of the electrode portion 16B of the conductive member 16 and smaller than the diameter D3 of the flange portion 16C. Therefore, when the electrode portion 16B of the conductive member 16 is inserted into the electrode through hole 14B of the bottom insulator 14 while the bottom insulator 14 is positioned on the -Z direction side of the fabric 21, the surface of the bottom insulator 14 facing the +Z direction around the electrode through hole 14B abuts against the flange portion 16C of the conductive member 16, as shown in Figure 13.
[0037] Furthermore, since flange portion 16C of conductive member 16 has a thickness in the Z direction that is approximately equal to the thickness of fabric 21, flange portion 16C of conductive member 16 and fabric 21 are sandwiched between the surface of top insulator 13 facing toward the -Z direction and the surface of bottom insulator 14 facing toward the +Z direction.
[0038] Furthermore, by pressing the bottom insulator 14 against the top insulator 13, the four bosses 13D of the top insulator 13, which penetrate the four cutouts 15B of the reinforcing sheet 15 and the four through holes 21D of the fabric 21, penetrate the four boss through holes 14C of the bottom insulator 14 and protrude toward the -Z direction side of the bottom insulator 14. Then, by thermally deforming the tips of the four bosses 13D protruding from the bottom insulator 14 toward the -Z direction side in the recesses 14D of the bottom insulator 14, the top insulator 13 and the bottom insulator 14 are fixed to each other, and the assembly of the bioinformation acquisition connector 11 is completed.
[0039] 14, in the bioinformation acquisition connector 11 assembled in this manner, the electrode portions 16B of the respective conductive members 16 are inserted into the electrode through-holes 14B of the bottom insulator 14, and the length in the Z direction of the cylindrical portion of the electrode portion 16B is approximately equal to the thickness in the Z direction of the flat portion 14A of the bottom insulator 14. For this reason, the convex electrode surface ES formed by the surface of the bulging portion adjacent to the -Z direction side of the cylindrical portion of the conductive member 16 protrudes in the -Z direction from the second exposed surface S2 formed by the surface of the bottom insulator 14 facing the -Z direction.
[0040] Therefore, when the user wears the garment with the back surface 21B of the fabric 21 facing inward and brings the electrode surface ES of the conductive member 16 protruding from the second exposed surface S2 into contact with the user's body surface, it is possible to obtain the user's biometric information via the electrode surface ES.
[0041] Furthermore, the contact portion 16A of each conductive member 16 penetrates the contact through hole 13B of the top insulator 13 and protrudes in the +Z direction from the first exposed surface S1 formed by the bottom surface of the recess 13A to form a plug contact PC. Therefore, by fitting a mating connector (not shown) into the bioinformation acquisition connector 11 and accommodating a part of the mating connector in the recess 13A of the top insulator 13 to connect the mating contact of the mating connector to the plug contact PC, the user's bioinformation acquired via the electrode surface ES can be transmitted with high accuracy from the contact portion 16A of the conductive member 16 through the mating connector to a measuring device, a communication device, or the like (not shown) without using wiring or the like.
[0042] In addition, since both the electrode surface ES for acquiring the user's biometric information and the plug contact PC for transmitting the acquired biometric information to the opposing connector are formed from a single conductive member 16, biometric information can be acquired and transmitted simply by mounting the biometric information acquisition connector 11 on clothing, making it possible to miniaturize the device mounted on clothing to acquire biometric information.
[0043] Although the contact portion 16A and the electrode portion 16B of the conductive member 16 both have an approximately cylindrical shape, it is sufficient that they have a columnar shape extending in the Z direction along the mating axis C, and the cross-sectional shape when cut along a cutting plane parallel to the XY plane is not limited to a circle but may be an ellipse, a rectangle, or another polygon, etc.
[0044] Embodiment 2 15 and 16 show a biometric information acquisition connector 31 according to embodiment 2. Similar to the biometric information acquisition connector 11 of embodiment 1, the biometric information acquisition connector 31 is mounted on the fabric 21 of clothing and is used, for example, as a clothing-side connector for fitting a wearable device.
[0045] The connector for acquiring biological information 31 has a housing 12 made of an insulating material, similar to the connector for acquiring biological information 11 of the first embodiment, and the housing 12 holds two plug contacts PC. The housing 12 has a top insulator 13 arranged on a front surface 21A of the material 21 and a bottom insulator 14 arranged on a back surface 21B of the material 21.
[0046] The two plug contacts PC protrude perpendicularly to a first exposed surface S1 formed by the bottom surface of the recess 13A of the top insulator 13. Moreover, two electrode surfaces ES are disposed and exposed on a second exposed surface S2 formed on the bottom insulator .
[0047] 17 and 18 show assembly diagrams of the connector for acquiring biological information 31. The reinforcing sheet 15 is disposed on the -Z side of the top insulator 13, two contact members 37 are disposed on the -Z side of the reinforcing sheet 15, and the fabric 21 is disposed on the -Z side of the two contact members 37. Furthermore, two electrode members 38 are disposed on the -Z side of the fabric 21, and the bottom insulator 14 is disposed on the -Z side of the two electrode members 38.
[0048] The connector 31 for acquiring bioinformation of embodiment 2 is similar to the connector 11 for acquiring bioinformation of embodiment 1 in that it uses two contact members 37 and two electrode members 38 instead of the two conductive members 16, and the top insulator 13, bottom insulator 14 and reinforcing sheet 15 are the same as those used in embodiment 1.
[0049] As shown in FIG. 19, the contact member 37 is formed from a conductive material such as a metal, and has a cylindrical tubular portion 37A extending in the Z direction along the mating axis C, and a contact side flange 37B extending along the XY plane from the -Z direction end of the tubular portion 37A. As shown in FIG. 20, a recess 37C that is open toward the -Z direction is formed inside the cylindrical portion 37A.
[0050] 5 has an inner diameter that is slightly larger than the maximum diameter D11 of the cylindrical portion 37A of the contact member 37 and smaller than the diameter D13 of the contact side flange 37B. In addition, the length L11 of the cylindrical portion 37A in the Z direction is set to be longer than the thickness of the bottom portion of the recess 13A of the top insulator 13 in the Z direction.
[0051] As shown in Figures 21 and 22, the electrode member 38 is a solid member made of a conductive material such as a metal, and has a first cylindrical portion 38A that is approximately cylindrical and extends in the Z direction along the mating axis C, a second cylindrical portion 38B that is approximately cylindrical and adjacent to the -Z direction side of the first cylindrical portion 38A and extends in the Z direction along the mating axis C, and a brim-shaped electrode side flange 38C that protrudes along the XY plane from the boundary between the first cylindrical portion 38A and the second cylindrical portion 38B. Further, four ribs 38D are formed on the outer periphery of the first cylindrical portion 38A. The ribs 38D extend linearly in the Z direction and are disposed at rotation angles of 90 degrees around the fitting axis C from each other. Such an electrode member 38 can be produced by, for example, pressing or cold rolling.
[0052] 7 has an inner diameter that is slightly larger than the diameter D22 of the second cylindrical portion 38B of the electrode member 38 and smaller than the diameter D23 of the electrode side flange 38C. The second cylindrical portion 38B of the electrode member 38 includes a cylindrical portion extending in the Z direction by a length L22 along the fitting axis C and a bulging portion bulging in the -Z direction from the cylindrical portion, and a convex electrode surface ES is formed by the surface of the bulging portion. The length L22 of the cylindrical portion in the Z direction is set to be approximately equal to the thickness of the flat portion 14A of the bottom insulator 14 in the Z direction.
[0053] A maximum diameter D21 of the first columnar portion 38A at the portion where the rib 38D is arranged is slightly larger than an inner diameter D12 of the recess 37C of the tubular portion 37A of the contact member 37, and a length L21 in the Z direction of the first columnar portion 38A is shorter than a depth in the Z direction of the recess 37C of the tubular portion 37A of the contact member 37. As a result, by press-fitting the first columnar portion 38A of the electrode member 38 into the recess 37C of the tubular portion 37A of the contact member 37 from the -Z direction, the contact member 37 and the electrode member 38 are coupled to each other and electrically connected as shown in Fig. 23, and the conductive member 36 in the second embodiment is formed. Incidentally, a spring portion (not shown) may be formed on the electrode member 38 so that the contact member 37 and the electrode member 38 are in elastic contact with each other via the spring portion.
[0054] The contact member 37 and the electrode member 38 respectively form the contact portion and the electrode portion of the conductive member 36, and the contact side flange 37B of the contact member 37 and the electrode side flange 38C of the electrode member 38 overlap each other in the Z direction to form the flange portion 36C of the conductive member 36. In addition, the diameter D13 of the contact side flange 37B of the contact member 37 and the diameter D23 of the electrode side flange 38C of the electrode member 38 shown in Figures 20 and 22 are equal to each other, and the sum of the Z-direction thickness of the contact side flange 37B and the Z-direction thickness of the electrode side flange 38C, i.e., the Z-direction thickness of the flange portion 36C, is formed to be approximately equal to the thickness of the material 21.
[0055] When assembling the connector 31 for acquiring bioinformation, first, the reinforcing sheet 15 is placed on the surface of the top insulator 13 facing the -Z direction so that the four bosses 13D of the top insulator 13 penetrate the four notches 15B of the reinforcing sheet 15, and the tubular portions 37A of the two contact members 37 are inserted into the two contact through holes 13B of the top insulator 13 from the -Z direction through the openings 15A of the reinforcing sheet 15.
[0056] Next, the substrate 21 is placed on the surface facing the -Z direction of the reinforcing sheet 15 so that the four bosses 13D of the top insulator 13 penetrate the four through holes 21D of the substrate 21, and the first cylindrical portions 38A of the two electrode members 38 are pressed from the -Z direction into the recesses 37C of the two contact members 37 through the two through holes 21C of the substrate 21. This forms two conductive members 36, each as shown in FIG.
[0057] In this state, the second cylindrical portions 38B of the two electrode members 38, each of which forms a conductive member 36, are inserted into the two electrode through holes 14B of the bottom insulator 14, while the bottom insulator 14 is placed on the surface of the fabric 21 facing the -Z direction from the -Z direction, and pressed in the +Z direction toward the top insulator 13. Furthermore, by thermally deforming the tips of the four bosses 13D of the top insulator 13 that pass through the four boss through holes 14C of the bottom insulator 14 and protrude toward the -Z direction side of the bottom insulator 14, the top insulator 13 and the bottom insulator 14 are fixed to each other, and the assembly of the bioinformation acquisition connector 31 is completed.
[0058] In the bioinformation acquisition connector 31 assembled in this manner, as shown in Figure 24, the flange portion 36C of the conductive member 36 is sandwiched between the surface of the top insulator 13 facing the -Z direction and the surface of the bottom insulator 14 facing the +Z direction, thereby fixing the conductive member 36 to the top insulator 13 and the bottom insulator 14.
[0059] The convex electrode surfaces ES of the electrode members 38 constituting each of the conductive members 36 protrude in the -Z direction from a second exposed surface S2 formed by the surface of the bottom insulator 14 facing the -Z direction. In addition, the tubular portion 37A of the contact member 37 forming each conductive member 36 penetrates the contact through hole 13B of the top insulator 13 and protrudes in the +Z direction from the first exposed surface S1 formed by the bottom surface of the recess 13A to form a plug contact PC.
[0060] Therefore, in the connector for acquiring bioinformation 31, as in the connector for acquiring bioinformation 11 of the embodiment 1, the electrode surface ES protruding from the second exposed surface S2 is brought into contact with the body surface of the user, thereby acquiring the bioinformation of the user through the electrode surface ES. Moreover, by fitting a mating connector (not shown) into the connector for acquiring bioinformation 31 and connecting a mating contact of the mating connector to the plug contact PC, the bioinformation of the user acquired through the electrode surface ES can be transmitted with high accuracy from the contact member 37 of the conductive member 36 through the mating connector to a measuring device, a communication device, or the like (not shown) without using wiring or the like.
[0061] In addition, since both the electrode surface ES for acquiring the user's biometric information and the plug contact PC for transmitting the acquired biometric information to the opposing connector are formed from a single conductive member 36, acquisition and transmission of biometric information can be performed simply by mounting the biometric information acquisition connector 31 on clothing, making it possible to miniaturize the device mounted on clothing for acquiring biometric information.
[0062] The tubular portion 37A of the contact member 37 has a cylindrical shape, and the first cylindrical portion 38A and the second cylindrical portion 38B of the electrode member 38 have an approximately cylindrical shape, but it is sufficient for both to have a columnar shape extending in the Z direction along the mating axis C, and the cross-sectional shape when cut along a cutting plane parallel to the XY plane is not limited to a circle, and may be an ellipse, a rectangle, any other polygon, etc. However, since the first columnar portion 38A of the electrode member 38 is press-fitted into the recess 37C of the tubular portion 37A of the contact member 37, it is preferable that the cross-sectional shapes of the first columnar portion 38A and the recess 37C correspond to each other.
[0063] In embodiment 2, contact member 37 and electrode member 38 are configured as separate parts, and therefore there is no need to form contact member 37 and electrode member 38 from the same material. For example, contact member 37 can be formed from a material suitable for contact with a mating contact of a mating connector, and electrode member 38 can be formed from a material suitable for contact with the user's body surface.
[0064] In the first and second embodiments, various types of bioinformation of the user can be obtained by contacting the electrode surface ES of the conductive member 16, 36 with the body surface of the user, and the bioinformation acquisition connectors 11, 31 in the first and second embodiments have two conductive members 16, 36. Therefore, even bioinformation such as heart rate and electrocardiogram waveform can be acquired with high accuracy by only using the bioinformation acquisition connectors 11, 31. However, the number of conductive members is not limited to two, and a bioinformation acquisition connector having three or more conductive members can be configured.
[0065] In addition, in embodiments 1 and 2, electrode portion 16B of conductive member 16 having electrode surface ES protruding from second exposed surface S2 and electrode member 38 of conductive member 36 are formed from metal or the like, but this is not limited to this and they may also be formed from a flexible conductive material such as conductive rubber.
[0066] Third embodiment 25 shows a connector 41 for acquiring biological information according to embodiment 3. This connector 41 for acquiring biological information is configured in such a way that a bottom insulator 44 is used instead of the bottom insulator 14 in the connector 11 for acquiring biological information according to embodiment 1, and other configurations are similar to those of the connector 11 for acquiring biological information according to embodiment 1.
[0067] In the connector for acquiring biological information 41, similarly to the connector for acquiring biological information 11 of the first embodiment, the electrode surfaces ES of the two conductive members 16 are exposed in a state of protruding in the -Z direction from the second exposed surface S2 of the bottom insulator 44. The bottom insulator 44 has lubricant reservoirs 44A each consisting of annular grooves formed along the outer periphery of each of the two electrode surfaces ES exposed on the second exposed surface S2. Except for the fact that these lubricant reservoirs 44A are formed, the bottom insulator 44 has the same configuration as the bottom insulator 14 of the first embodiment.
[0068] In order to obtain the user's biometric information through the electrode surface ES, it is desirable for the electrode surface ES to be in close contact with the user's body surface; for example, a medical lubricant can be applied to the user's body surface to bring the electrode surface ES into contact with the body surface. In the connector 41 for acquiring bioinformation of embodiment 3, a lubricant storage portion 44A consisting of a groove is formed on the outer periphery of the two electrode surfaces ES exposed on the second exposed surface S2 of the bottom insulator 44, so that when the electrode surfaces ES are brought into contact with the user's body surface, the medical lubricant applied to the user's body surface is stored inside the lubricant storage portion 44A.
[0069] Furthermore, even if a medical lubricant is not used, moisture such as sweat is stored inside the lubricant storage section 44A and supplied between the electrode surface ES and the user's body surface, thereby maintaining adhesion between the electrode surface ES and the user's body surface, and biometric information can be obtained with high accuracy. The lubricant reservoir 44A in the third embodiment may be applied to the connector 31 for acquiring biological information in the second embodiment, so that the lubricant reservoir 44A is formed in the bottom insulator 14 of the connector 31 for acquiring biological information.
[0070] Fourth embodiment 26 shows a connector 51 for acquiring biological information according to embodiment 4. The connector 51 for acquiring biological information is similar to the connector 11 for acquiring biological information according to embodiment 1 except that an adhesive layer 52 is disposed on the second exposed surface S2 of the bottom insulator 14 facing the -Z direction in the connector 11 for acquiring biological information according to embodiment 1.
[0071] The adhesive layer 52 is intended to adhere the bioinformation acquisition connector 51 to the user's body surface by utilizing its adhesiveness, and the adhesive layer 52 can be formed using existing elastomers including, for example, silicone rubber, urethane rubber, etc. By adhering the biometric information acquisition connector 51 to the user's body surface using the adhesive layer 52, the adhesion between the electrode surface ES and the user's body surface is improved, making it possible to acquire biometric information with high accuracy via the electrode surface ES. The adhesive layer 52 in the fourth embodiment can also be applied to the connector for acquiring biological information 31 in the second embodiment or the connector for acquiring biological information 41 in the third embodiment.
[0072] The bottom insulator 14 in the connector 11 for acquiring bioinformation according to the first embodiment and the connector 31 for acquiring bioinformation according to the second embodiment, and the bottom insulator 44 in the connector 41 for acquiring bioinformation according to the third embodiment may be made of an insulating material having adhesive properties. As the insulating material having adhesive properties, for example, an elastomer containing silicone rubber, urethane rubber, or the like may be used. If the bottom insulators 14, 44 are formed from such an adhesive insulating material, the bioinformation acquisition connectors 11, 31, 41 are adhered to the user's body surface, improving adhesion between the electrode surface ES and the user's body surface, and bioinformation can be acquired with high accuracy via the electrode surface ES.
[0073] Furthermore, the top insulator 13 and the bottom insulator 14 in the connector 11 for acquiring bioinformation according to the first embodiment, the connector 31 for acquiring bioinformation according to the second embodiment, and the connector 51 for acquiring bioinformation according to the fourth embodiment, and the top insulator 13 and the bottom insulator 44 in the connector 41 for acquiring bioinformation according to the third embodiment can each be formed from a flexible insulating material such as an elastomer. By using such top insulator 13 and bottom insulator 14, 44, the connectors 11, 31, 41, 51 for acquiring bioinformation can be curved to fit the user's body surface, and the adhesion between the electrode surface ES and the user's body surface can be further improved.
[0074] When constructing a connector for acquiring biometric information that has a large number of conductive members 16, 36, it is necessary to increase the area along the XY plane of the top insulator 13 and the bottom insulators 14, 44 according to the number of conductive members 16, 36. However, by forming the top insulator 13 and the bottom insulators 14, 44 from a flexible insulating material, close contact between the electrode surface ES of each conductive member 16, 36 and the user's body surface can be ensured, enabling biometric information to be acquired with high accuracy.
[0075] In addition, the electrode surfaces ES of the respective conductive members 16, 36 can be roughened by forming irregularities, including grooves, on the electrode surfaces ES. By forming such electrode surfaces ES, moisture such as medical lubricants and sweat can be easily retained on the electrode surfaces ES, improving the adhesion between the electrode surfaces ES and the user's body surface, making it possible to acquire bioinformation with high accuracy.
[0076] Fifth embodiment FIG. 27 shows a biometric information acquisition connector 61 according to the fifth embodiment and a clothing material 71 that is an object to be mounted thereon. Similar to the connector 11 for acquiring biometric information of embodiment 1, the connector 61 for acquiring biometric information has a top insulator 13 arranged on the surface on the +Z direction side of the reinforcing sheet 15, and two plug contacts PC each protruding in the +Z direction from a first exposed surface S1 consisting of the bottom surface of the recess 13A of the top insulator 13.
[0077] However, the biometric information acquisition connector 61 is not held by the fabric 71 of the clothing, and the fabric 71 is disposed away from the biometric information acquisition connector 61 in the -Z direction. Also, the fabric 71 has an opening 71A formed therein corresponding to the biometric information acquisition connector 61.
[0078] As shown in Figure 28, the connector 61 for acquiring bioinformation has a bottom insulator 64 arranged on the -Z side of the reinforcing sheet 15, and the +Z side surface of the bottom insulator 64 contacts the -Z side surface of the reinforcing sheet 15 and the -Z side surface of the top insulator 13, respectively, and the flange portions 16C of the two conductive members 16 are sandwiched between the top insulator 13 and the bottom insulator 64, and the top insulator 13 and the bottom insulator 64 are fixed to each other.
[0079] As with the connector 11 for acquiring bioinformation of embodiment 1, two conductive members 16 form two plug contacts PC and two electrode surfaces ES, and the two plug contacts PC protrude in the +Z direction from the first exposed surface S1 of the top insulator 13, and the two electrode surfaces ES protrude in the -Z direction from the second exposed surface S2 of the bottom insulator 64.
[0080] Such a biometric information acquisition connector 61 is placed on a garment fabric 71, as shown in Fig. 29. An opening 71A of the fabric 71 has a size slightly larger than the bottom insulator 64, and the bottom insulator 64 is inserted into the opening 71A, and the reinforcing sheet 15 comes into contact with the surface of the fabric 71 around the opening 71A. In this state, for example, the reinforcing sheet 15 can be sewn to the fabric 71, whereby the biometric information acquisition connector 61 can be mounted on the fabric 71.
[0081] According to the biometric information acquisition connector 61 of embodiment 5, there is no need to sandwich the fabric 71 between the top insulator 13 and the bottom insulator 64 when assembling the biometric information acquisition connector 61, and it is possible to mount the biometric information acquisition connector 61 on the fabric 71 after assembly. Therefore, by mounting the biometric information acquisition connector 61 on ordinary clothing, the clothing can be used as so-called smart clothing that can acquire the biometric information of the user simply by wearing it. Furthermore, when the clothing used as smart clothing deteriorates, the biometric information acquisition connector 61 can be attached to a new piece of clothing and reused.
[0082] The reinforcing sheet 15 can be fixed to the fabric 71 by various methods, such as sewing, adhesion, fastening with a zipper, etc. Also in embodiment 5, by forming the top insulator 13 and the bottom insulator 64 in the connector 61 for acquiring biometric information from a flexible insulating material such as an elastomer, it is possible to configure the connector 61 for acquiring biometric information to be bendable to fit the user's body surface.
[0083] In the fifth embodiment, the connector 61 for acquiring biometric information can be mounted on the fabric 71 by fixing the reinforcing sheet 15 to the fabric 71 after assembling the connector 61 for acquiring biometric information, so that the top insulator 13, the bottom insulator 64, and the reinforcing sheet 15 can be integrally molded from an insulating material while the two conductive members 16 are insert molded. In this case, the connector 61 for acquiring biometric information that can be bent can be formed by molding using a flexible insulating material such as an elastomer.
[0084] Furthermore, the biometric information acquisition connector 31 of embodiment 2, the biometric information acquisition connector 41 of embodiment 3, and the biometric information acquisition connector 51 of embodiment 4 can also be configured in a similar manner so that the biometric information acquisition connector is mounted on the fabric after assembly.
