Description

Technical Field

[0001] The present invention relates to a biological information acquisition connector, and more particularly to a biological information acquisition connector that is mounted on an attachment object constituted by a garment worn by a user and is engaged with a counterpart connector. Background Art

[0002] For example, Patent Document 1 discloses an electrode unit for obtaining biological information of a user such as heart rate. Fig.30 As shown, the electrode unit includes an embroidery-type badge portion 1 and a fastener portion 3 for fixing the badge portion 1 to clothing 2. The badge portion 1 has an electrode portion 4 and a pin 5 protruding from the electrode portion 4. The badge portion 1 is fixed to the clothing 2 by piercing the pin 5 into the clothing 2 and inserting the front end of the pin 5 protruding from the clothing 2 into the insertion hole 6 of the fastener portion 3.

[0003] The electrode unit 4 is brought into contact with or close to the user's body surface 7 to acquire the user's biological information, and the acquired biological information is transmitted to an external device such as a measuring device or a communication device (not shown) via a cable 8 connected to the buckle unit 3 .

[0007] 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 the accuracy of the transmitted biological information may be reduced.

[0008] Alternatively, a connector (not shown) may be connected to the cable 8 to transmit biological information to a measuring device, a communication device, etc. via the connector. However, in this case, an increase in resistance value due to the use of the cable 8 cannot be avoided. In addition, since the connector is connected to the Fig.30 The electrode unit shown also causes a problem of increasing the size of the device attached to the clothing 2 for acquiring biological information. Summary of the invention

[0009] The present invention has been made to solve such conventional problems, and an object of the present invention is to provide a small biological information acquisition connector capable of acquiring and transmitting a user's biological information with high accuracy.

[0010] The biological information acquisition connector of the present invention is mounted on an object of attachment constituted by a garment worn by a user, and is mated with a counterpart connector along a predetermined mating direction. The biological information acquisition connector comprises:

[0011] a housing mounted on an object to be mounted and having a first exposed surface facing the side opposite to the body surface of the user and a second exposed surface facing the body surface side of the user; and

[0012] A plurality of conductive members each extend in the mating direction and are held in the housing in a state of penetrating the housing from the first exposed surface to the second exposed surface in the mating direction.

[0013] The multiple conductive components respectively include: a conductive contact portion, which protrudes from a first exposed surface of the shell and is connected to a counterpart contact of the counterpart connector when mated with the counterpart connector; and a conductive electrode portion, which protrudes from a second exposed surface of the shell and is used to obtain the user's biological information.

[0014] The plurality of conductive members may be respectively constituted by a single member in which a contact portion and an electrode portion are integrally formed with each other along the mating direction.

[0015] The contact portion and the electrode portion each have a column shape extending in the mating direction.

[0016] In this case, it is preferable that each of the plurality of conductive members has a flange portion extending from a boundary portion between the contact portion and the electrode portion in a direction perpendicular to the fitting direction.

[0017] Furthermore, it is preferred that the housing is composed of a top insulator having a first exposed surface and a bottom insulator having a second exposed surface.

[0018] The top insulator has a plurality of contact through holes, each of which is smaller than the flange portion and through which the contact portions pass.

[0019] The bottom insulator has a plurality of electrode through holes, each of which is smaller than the flange portion and through which the electrode portion passes.

[0020] The top insulator and the bottom insulator are fixed to each other in a state where the contact parts of the multiple conductive components pass through the multiple contact through holes, the electrode parts of the multiple conductive components pass through the multiple electrode through holes, and the flange parts of the multiple conductive components are sandwiched between the top insulator and the bottom insulator.

[0021] Furthermore, the plurality of conductive members may each be composed of a contact member forming a contact portion and an electrode member connected to the contact member and forming an electrode portion.

[0022] The contact member has a cylindrical portion extending in the mating direction and having a recess formed inside.

[0023] The electrode member is partially inserted into the recess and contacts the inner surface of the recess, thereby electrically connecting the electrode member to the contact member.

[0024] In this case, it is preferred that the contact member has a contact-side flange extending from an end of the cylindrical portion in a direction perpendicular to the fitting direction.

[0025] The electrode component comprises: a first cylindrical portion extending along the mating direction and inserted into the recess of the contact component as a part of the electrode component; a second cylindrical portion extending in the mating direction in the opposite direction to the first cylindrical portion; and an electrode side flange extending from a boundary portion between the first cylindrical portion and the second cylindrical portion in a direction orthogonal to the mating direction.

[0026] The contact-side flange and the electrode-side flange overlap each other in the mating direction to form a flange portion.

[0027] Furthermore, it is preferred that the housing is composed of a top insulator having a first exposed surface and a bottom insulator having a second exposed surface.

[0028] The top insulator has a plurality of contact through holes, each of which is smaller than the contact side flange and through which the cylindrical portion of the contact member passes.

[0029] The bottom insulator has a plurality of electrode through holes, each of which is penetrated by the second cylindrical portion of the electrode member and is smaller than the electrode side flange.

[0030] The top insulator and the bottom insulator are fixed to each other in a state where the cylindrical portion of the contact component of the multiple conductive components penetrates the multiple contact through holes, the second cylindrical portion of the electrode component of the multiple conductive components penetrates the multiple electrode through holes, and the flange portions of the multiple conductive components are clamped between the top insulator and the bottom insulator.

[0031] Preferably, the housing is attached to the attachment object by fixing the top insulator and the bottom insulator to each other in a state where the attachment object is sandwiched between the top insulator and the bottom insulator.

[0032] The reinforcing sheet may be provided, the reinforcing sheet being held by the housing and having a fixing portion extending outward from the outer peripheral portion of the housing, and the housing may be attached to the attachment object by being fixed to the attachment object by the fixing portion.

[0033] In this case, the case and the reinforcing sheet may be integrally molded from insulating resin.

[0034] The housing may include a lubricant reservoir formed of a groove formed on the second exposed surface and arranged around the electrode portion protruding from the second exposed surface.

[0035] An adhesive layer may be provided on the second exposed surface.

[0036] The bottom insulator may be formed of an elastomer.

[0037] Alternatively, an elastomer may be used as the insulating resin for integrally molding the housing and the reinforcing sheet.

[0038] The electrode portion may include a roughened electrode surface that is exposed from the second exposed surface.

[0039] Preferably, the device is attached to clothing as an attachment object.

DETAILED DESCRIPTION

[0074] Hereinafter, embodiments of the present invention will be described based on the drawings.

[0075] Implementation Method 1

[0076] Figure 1 and Figure 2 The biological information acquiring connector 11 according to Embodiment 1 is shown. The biological information acquiring connector 11 is used as, for example, a clothing-side connector for fitting a wearable device, and is attached to a cloth 21 of clothing as an attachment object.

[0077] The biological information acquiring connector 11 has a housing 12 made of an insulating material. In the housing 12, two plug contacts PC are held so as to protrude perpendicularly to the fabric 21.

[0078] The housing 12 has a top insulator 13 disposed on the surface 21A of the fabric 21 and a bottom insulator 14 disposed on the back surface 21B of the fabric 21. The surface 21A of the fabric 21 is a surface facing the outside of the garment and faces the side opposite to the user's body surface when the user wears the garment, and the back surface 21B of the fabric 21 is a surface facing the inside of the garment and faces the user's body surface when the user wears the garment.

[0079] like Figure 1 As shown, the top insulator 13 is arranged on the surface 21A of the fabric 21 via the reinforcing sheet 15, and has a recess 13A opened in the direction opposite to the fabric 21. The bottom surface of the recess 13A forms a planar first exposed surface S1 exposed to the surface 21A side of the fabric 21, and the two plug contacts PC protrude perpendicularly relative to the first exposed surface S1.

[0080] like Figure 2 As shown, the bottom insulator 14 is directly arranged on the back surface 21B of the fabric 21, and has a planar second exposed surface S2 exposed to the back surface 21B side of the fabric 21. Two electrode surfaces ES are arranged on the second exposed surface S2 and the two electrode surfaces ES are exposed. The two electrode surfaces ES are arranged at positions corresponding to the two plug contacts PC.

[0081] Here, for convenience, the first exposed surface S1 and the second exposed surface S2 extend along the XY plane, and 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 of the biological information acquisition connector 11 and the unillustrated mating connector.

[0082] The two electrode surfaces ES are exposed in a state of protruding in the −Z direction from the second exposed surface S2 of the bottom insulator 14 .

[0083] Figure 3 and Figure 41 shows an assembly diagram of the biological information acquisition connector 11. A reinforcing sheet 15 is arranged on the -Z direction side of the top insulator 13, and a fabric 21 is arranged on the -Z direction side of the reinforcing sheet 15. In addition, two conductive members 16 are arranged on the -Z direction side of the fabric 21, and a bottom insulator 14 is arranged on the -Z direction side of the two conductive members 16.

[0084] The conductive member 16 forms both the plug contacts PC protruding from the first exposed surface S1 in the +Z direction and the electrode surface ES exposed from the second exposed surface S2 in the −Z direction.

[0085] like Figure 5 As shown, two contact through holes 13B are formed in the recess 13A of the top insulator 13, each of which penetrates the top insulator 13 in the Z direction. The recess 13A constitutes a mating connector receiving portion for receiving a part of a mating connector (not shown), and the two contact through holes 13B correspond to the two plug contacts PC.

[0086] like Figure 6 As shown, a step portion 13C is formed on the peripheral edge of the surface of the top insulator 13 facing the -Z direction so as to surround the two contact through holes 13B. The step portion 13C has a depth substantially equal to the thickness of the reinforcing sheet 15. In addition, four protrusions 13D are formed on the step portion 13C so as to protrude in the -Z direction.

[0087] like Figure 7 As shown, the bottom insulator 14 has a flat plate portion 14A, and two electrode through holes 14B are formed in the flat plate portion 14A, each penetrating the flat plate portion 14A in the Z direction. The two electrode through holes 14B are arranged at positions corresponding to the two contact through holes 13B of the top insulator 13 .

[0088] Furthermore, four projection through holes 14C are formed in the flat plate portion 14A. The four projection through holes 14C correspond to the plurality of projections 13D of the top insulator 13 and penetrate the flat plate portion 14A in the Z direction.

[0089] like Figure 8 As shown in FIG. 1 , a concave portion 14D is formed on the surface of the bottom insulator 14 that forms the second exposed surface S2 and faces the −Z direction so as to surround each protrusion through hole 14C. The concave portion 14D is used to accommodate the front end of the protrusion 13D of the top insulator 13 that passes through the protrusion through hole 14C and is thermally deformed when the biological information acquisition connector 11 is assembled.

[0090] like Fig. 9 and Fig.10As shown, the conductive component 16 is a solid component formed of a conductive material such as metal, and includes: 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 flange portion 16C extending from the boundary portion between the contact portion 16A and the electrode portion 16B along the XY plane. Such a conductive component 16 can be manufactured, for example, by stamping or cold rolling.

[0091] The fitting axis C is an axis that passes through the center of the conductive member 16 and extends in the fitting direction between the biological information acquiring connector 11 and the mating connector.

[0092] Figure 5 The contact through hole 13B of the top insulator 13 shown has an inner diameter 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 of the contact portion 16A of the conductive member 16 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.

[0093] Figure 7 The electrode through hole 14B of the bottom insulator 14 shown 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. The electrode portion 16B of the conductive member 16 includes a cylindrical portion extending along the fitting axis C in the Z direction by a length L2, and a bulging portion bulging from the cylindrical portion in the -Z direction, and a convex electrode surface ES is formed on the surface of the bulging portion. The length L2 of the cylindrical portion in the Z direction is set to be substantially equal to the thickness of the flat plate portion 14A of the bottom insulator 14 in the Z direction.

[0094] Furthermore, the flange portion 16C of the conductive member 16 has a thickness in the Z direction that is substantially equal to the thickness of the fabric 21 .

[0095] like Fig.11 As shown, the reinforcing sheet 15 is used to reinforce the cloth 21 of the clothing to which the biological information acquisition connector 11 is attached, and is made of an insulating material and has an opening 15A formed in the center. In addition, four cutouts 15B corresponding to the four protrusions 13D of the top insulator 13 are formed along the periphery of the opening 15A of the reinforcing sheet 15.

[0096] like Fig.12 As shown, 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 protrusions 13D of the top insulator 13 are formed in the cloth 21 of the clothing.

[0097] Furthermore, the through hole 21C of the cloth 21 has a diameter that is substantially equal to or slightly larger than the diameter D3 of the flange portion 16C of the conductive member 16 .

[0098] 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 arranged at positions aligned with each other in the Z direction.

[0099] Furthermore, the four protrusions 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 protrusion through holes 14C of the bottom insulator 14 are arranged at positions aligned with each other in the Z direction.

[0100] When assembling the biological information acquisition connector 11, first, the reinforcing sheet 15 and the fabric 21 are sequentially arranged on the surface of the top insulator 13 facing the -Z direction side so that the four protrusions 13D of the top insulator 13 penetrate the four cutouts 15B of the reinforcing sheet 15 and the four through holes 21D of the fabric 21. At this time, the peripheral edge of the opening 15A of the reinforcing sheet 15 is accommodated in the step 13C of the top insulator 13, and the two through holes 21C of the fabric 21 are located 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.

[0101] Furthermore, the contact parts 16A of the two conductive members 16 are inserted from the -Z direction into the two through holes 21C of the cloth 21 and the two contact through holes 13B of the top insulator 13. Here, the contact through holes 13B of the top insulator 13 have an inner diameter slightly larger than the diameter D1 of the contact parts 16A of the conductive member 16 and smaller than the diameter D3 of the flange part 16C, and the through hole 21C of the cloth 21 has a diameter substantially equal to or slightly larger than the diameter D3 of the flange part 16C of the conductive member 16.

[0102] Therefore, when contact portion 16A of conductive member 16 is inserted into through hole 21C of fabric 21 and contact through hole 13B of top insulator 13 , flange portion 16C of conductive member 16 abuts against a surface of top insulator 13 facing the −Z direction around contact through hole 13B.

[0103] In this state, the electrode portions 16B of the two conductive members 16 are inserted into the two electrode through holes 14B of the bottom insulator 14 , and the bottom insulator 14 is placed on the surface of the cloth 21 facing the −Z direction from the −Z direction and pressed toward the top insulator 13 in the +Z direction.

[0104] In addition, 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, if the electrode portion 16B of the conductive member 16 is inserted into the electrode through hole 14B of the bottom insulator 14 and the bottom insulator 14 is arranged on the -Z direction side of the fabric 21, Fig.13 As shown, the surface of the bottom insulator 14 facing the +Z direction side in the periphery of the electrode through hole 14B abuts against the flange portion 16C of the conductive member 16 .

[0105] Furthermore, the flange portion 16C of the conductive component 16 has a thickness in the Z direction that is substantially equal to the thickness of the fabric 21 , and thus the flange portion 16C of the conductive component 16 and the fabric 21 are sandwiched between the surface of the top insulator 13 facing the −Z direction side and the surface of the bottom insulator 14 facing the +Z direction side.

[0106] Furthermore, by pressing the bottom insulator 14 against the top insulator 13, the four protrusions 13D of the top insulator 13 that pass through the four cutouts 15B of the reinforcing sheet 15 and the four through holes 21D of the fabric 21 pass through the four protrusion through holes 14C of the bottom insulator 14 and protrude toward the -Z direction side of the bottom insulator 14. Therefore, by causing the front end portions of the four protrusions 13D that protrude toward the -Z direction side from the bottom insulator 14 to be thermally deformed in the recessed portions 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 biological information acquiring connector 11 is completed.

[0107] In the biological information acquisition connector 11 assembled in this way, Fig.14 As shown, the electrode portion 16B of each conductive member 16 is inserted into the electrode through hole 14B of the bottom insulator 14, and the length of the cylindrical portion of the electrode portion 16B in the Z direction is substantially equal to the thickness of the flat plate portion 14A of the bottom insulator 14 in the Z direction. Therefore, the convex electrode surface ES formed by the surface of the bulging portion of the conductive member 16 adjacent to the -Z direction side of the cylindrical portion protrudes in the -Z direction from the second exposed surface S2 formed by the surface of the bottom insulator 14 facing the -Z direction.

[0108] Therefore, the user wears the clothes with the back surface 21B of the cloth 21 facing inside, and the electrode surface ES of the conductive member 16 protruding from the second exposed surface S2 contacts the user's body surface, thereby acquiring the user's biological information through the electrode surface ES.

[0109] In addition, the contact portion 16A of each conductive member 16 passes through the contact through hole 13B of the top insulator 13, protrudes from the first exposed surface S1 formed by the bottom surface of the recess 13A in the +Z direction, and constitutes a plug contact PC. Therefore, by fitting a mating connector (not shown) with the biometric information acquisition connector 11, accommodating a portion of the mating connector in the recess 13A of the top insulator 13, and connecting the mating contact of the mating connector to the plug contact PC, the biometric information of the user acquired via the electrode surface ES can be transmitted from the contact portion 16A of the conductive member 16 to a measuring device, a communication device, etc. (not shown) via the mating connector with high accuracy without using wiring or the like.

[0110] In addition, the electrode surface ES for acquiring the user's biological information and the plug contact PC for transmitting the acquired biological information to the connector on the other side are both formed by a conductive component 16. Therefore, the biological information can be acquired and transmitted only by installing the connector 11 for acquiring biological information on clothes, thereby realizing the miniaturization of the device installed on clothes for acquiring biological information.

[0111] In addition, the contact part 16A and the electrode part 16B of the conductive component 16 both have a roughly cylindrical shape, but as long as they have a columnar shape extending in the Z direction along the mating axis C, the cross-sectional shape when cut along a cutting plane parallel to the XY plane is not limited to a circle, and can also be an ellipse, a rectangle, other polygons, etc.

[0112] Implementation Method 2

[0113] Fig.15 and Fig.16 A biological information acquisition connector 31 according to Embodiment 2 is shown. The biological information acquisition connector 31 is attached to the cloth 21 of clothing, similarly to the biological information acquisition connector 11 according to Embodiment 1, and is used as a clothing-side connector for fitting a wearable device, for example.

[0114] The biological information acquiring connector 31 , like the biological information acquiring connector 11 of the first embodiment, includes a housing 12 made of an insulating material, and the housing 12 holds two plug contacts PC.

[0115] The housing 12 includes a top insulator 13 disposed on a surface 21A of the fabric 21 and a bottom insulator 14 disposed on a back surface 21B of the fabric 21 .

[0116] The two plug contacts PC protrude perpendicularly with respect to a first exposed surface S1 formed by the bottom surface of the recessed portion 13A of the top insulator 13 .

[0117] Furthermore, two electrode surfaces ES are arranged on the second exposed surface S2 formed on the bottom insulator 14 and the two electrode surfaces ES are exposed.

[0118] Fig.17 and Fig.18 1 shows an assembly diagram of the biological information acquisition connector 31. The reinforcing sheet 15 is arranged on the -Z direction side of the top insulator 13, two contact members 37 are arranged on the -Z direction side of the reinforcing sheet 15, and the fabric 21 is arranged on the -Z direction side of the two contact members 37. In addition, two electrode members 38 are arranged on the -Z direction side of the fabric 21, and the bottom insulator 14 is arranged on the -Z direction side of the two electrode members 38.

[0119] In the biological information acquisition connector 31 of embodiment 2, two contact components 37 and two electrode components 38 are used to replace the two conductive components 16 in the biological information acquisition connector 11 of embodiment 1, and the top insulator 13, the bottom insulator 14 and the reinforcing plate 15 are the same as those used in embodiment 1.

[0120] like Fig.19 As shown, the contact member 37 is formed of a conductive material such as metal, and has a cylindrical portion 37A extending in the Z direction along the fitting axis C, and a contact side flange 37B extending along the XY plane from the -Z direction end of the cylindrical portion 37A.

[0121] like Fig. 20 As shown, a recessed portion 37C opened toward the -Z direction is formed inside the cylindrical portion 37A.

[0122] Figure 5 The contact through hole 13B of the top insulator 13 shown has an inner diameter 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 recessed portion 13A of the top insulator 13 in the Z direction.

[0123] like Fig.21 and Fig. 22 As shown, the electrode component 38 is a solid component formed of a conductive material such as metal, and has: a first cylindrical portion 38A of a roughly cylindrical shape, extending along the interlocking axis C in the Z direction; a second cylindrical portion 38B of a roughly cylindrical shape, adjacent to the -Z direction side of the first cylindrical portion 38A and extending in the Z direction along the interlocking axis C; and a flange-shaped electrode side flange 38C extending along the XY plane from the boundary between the first cylindrical portion 38A and the second cylindrical portion 38B.

[0124] Furthermore, four ribs 38D are formed on the outer circumference of the first cylindrical portion 38A. The four ribs 38D extend linearly in the Z direction and are arranged at a rotation angle of 90 degrees around the fitting axis C.

[0125] Such an electrode member 38 can be produced by, for example, press working or cold rolling working.

[0126] Figure 7 The electrode through hole 14B of the bottom insulator 14 shown has an inner diameter 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. In addition, the second cylindrical portion 38B of the electrode member 38 includes a cylindrical portion extending along the fitting axis C in the Z direction by a length L22, and a bulging portion bulging from the cylindrical portion in the -Z direction, and a convex electrode surface ES is formed by the surface of the bulging portion. In addition, the length L22 of the cylindrical portion in the Z direction is set to be substantially equal to the thickness of the flat plate portion 14A of the bottom insulator 14 in the Z direction.

[0127] The maximum diameter D21 of the first cylindrical portion 38A in the portion where the rib 38D is arranged is formed to be slightly larger than the inner diameter D12 of the recess 37C of the cylindrical portion 37A of the contact member 37, and the length L21 of the first cylindrical portion 38A in the Z direction is formed to be shorter than the depth in the Z direction of the recess 37C of the cylindrical portion 37A of the contact member 37. Thus, by pressing the first cylindrical portion 38A of the electrode member 38 into the recess 37C of the cylindrical portion 37A of the contact member 37 from the -Z direction, as shown in FIG. Fig.23 As shown, the contact member 37 and the electrode member 38 are linked to each other and electrically connected to form the conductive member 36 in the second embodiment.

[0128] Alternatively, a configuration may be adopted in which a spring portion (not shown) is formed on the electrode member 38 and the contact member 37 and the electrode member 38 are elastically contacted by the spring portion.

[0129] The contact member 37 and the electrode member 38 respectively form a contact portion and an 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, thereby forming a flange portion 36C of the conductive member 36 .

[0130] in addition, Fig. 20 and Fig. 22 The diameter D13 of the contact side flange 37B of the contact component 37 shown and the diameter D23 of the electrode side flange 38C of the electrode component 38 are equal to each other. In addition, the sum of the thickness of the contact side flange 37B in the Z direction and the thickness of the electrode side flange 38C in the Z direction, that is, the thickness of the flange portion 36C in the Z direction, is formed to be approximately equal to the thickness of the fabric 21.

[0131] When assembling the connector 31 for acquiring biological information, first, the reinforcing sheet 15 is arranged on the surface of the top insulator 13 facing the -Z direction side in such a manner that the four protrusions 13D of the top insulator 13 penetrate the four cutouts 15B of the reinforcing sheet 15, and the cylindrical portions 37A of the two contact components 37 are inserted into the two contact through holes 13B of the top insulator 13 from the -Z direction through the opening 15A of the reinforcing sheet 15.

[0132] Next, the fabric 21 is arranged on the surface of the reinforcing sheet 15 facing the -Z direction side so that the four protrusions 13D of the top insulator 13 penetrate the four through holes 21D of the fabric 21, and the first cylindrical portions 38A of the two electrode members 38 are pressed into the recesses 37C of the two contact members 37 from the -Z direction through the two through holes 21C of the fabric 21. Fig.23 Two conductive members 36 are shown.

[0133] In this state, the second cylindrical portions 38B of the two electrode components 38 that respectively form the conductive components 36 are inserted into the two electrode through holes 14B of the bottom insulator 14, and the bottom insulator 14 is arranged on the surface of the fabric 21 facing the -Z direction side from the -Z direction and pressed toward the top insulator 13 in the +Z direction.

[0134] Furthermore, by thermally deforming the front end portions of the four protrusions 13D of the top insulator 13 that penetrate the four protrusion 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, thereby completing the assembly of the connector 31 for acquiring biological information.

[0135] In the biological information acquisition connector 31 assembled in this way, Fig.24 As shown, the flange portion 36C of the conductive member 36 is sandwiched between the surface of the top insulator 13 facing the −Z direction side and the surface of the bottom insulator 14 facing the +Z direction side, so that the conductive member 36 is fixed to the top insulator 13 and the bottom insulator 14 .

[0136] The convex electrode surface ES of the electrode member 38 forming each conductive member 36 protrudes in the −Z direction from the second exposed surface S2 formed by the surface of the bottom insulator 14 facing the −Z direction.

[0137] Furthermore, the cylindrical portion 37A of the contact member 37 forming each conductive member 36 passes through 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, thereby forming a plug contact PC.

[0138] Therefore, in the biological information acquisition connector 31, similarly to the biological information acquisition connector 11 of Embodiment 1, by bringing the electrode surface ES protruding from the second exposed surface S2 into contact with the body surface of the user, the biological information of the user can be acquired through the electrode surface ES. In addition, by fitting the other-side connector (not shown) with the biological information acquisition connector 31 and connecting the other-side contact of the other-side connector to the plug contact PC, the biological information of the user acquired through the electrode surface ES can be transmitted from the contact member 37 of the conductive member 36 to a measuring device, a communication device, etc. (not shown) through the other-side connector with high accuracy without using wiring or the like.

[0139] In addition, the electrode surface ES for acquiring the user's biological information and the plug contact PC for transmitting the acquired biological information to the connector on the other side are both formed by a conductive component 36. Therefore, the biological information can be acquired and transmitted only by installing the connector 31 for acquiring biological information on clothes, thereby realizing the miniaturization of the device installed on clothes for acquiring biological information.

[0140] In addition, the tubular portion 37A of the contact component 37 has a cylindrical shape, and the first cylindrical portion 38A and the second cylindrical portion 38B of the electrode component 38 have a roughly cylindrical shape, but they all have to have a columnar shape extending in the Z direction along the interlocking axis C. The cross-sectional shape when cut with a cutting plane parallel to the XY plane is not limited to a circle, and can also be an ellipse, a rectangle, other polygons, etc.

[0141] However, since the first cylindrical portion 38A of the electrode member 38 is press-fitted into the recessed portion 37C of the cylindrical portion 37A of the contact member 37 , it is preferable that the cross-sectional shapes of the first cylindrical portion 38A and the recessed portion 37C correspond to each other.

[0142] In embodiment 2, the contact component 37 and the electrode component 38 are configured as different components from each other, and therefore these contact components 37 and electrode components 38 do not need to be formed of the same material. For example, the contact component 37 can be formed of a material suitable for contacting the other side contact of the other side connector, and the electrode component 38 can be formed of a material suitable for contacting the user's body surface.

[0143] By making the electrode surface ES of the conductive member 16, 36 in the first and second embodiments contact with the body surface of the user, various biological information of the user can be obtained. The connector 11, 31 for obtaining biological information in the first and second embodiments has two conductive members 16, 36. Therefore, even biological information such as heart rate and electrocardiogram waveform can be obtained with high accuracy by using only the connector 11, 31 for obtaining biological information. However, the conductive members are not limited to two, and a connector for obtaining biological information having three or more conductive members may be configured.

[0144] In the first and second embodiments, the electrode portion 16B of the conductive component 16 and the electrode component 38 of the conductive component 36 having the electrode surface ES protruding from the second exposed surface S2 are formed of metal or the like, but are not limited thereto and may be formed of a flexible conductive material such as conductive rubber.

[0145] Implementation 3

[0146] Fig.25 A biological information acquiring connector 41 according to Embodiment 3 is shown. In this biological information acquiring connector 41, a bottom insulator 44 is used instead of the bottom insulator 14 in the biological information acquiring connector 11 according to Embodiment 1, and other structures are the same as those of the biological information acquiring connector 11 according to Embodiment 1.

[0147] In the biological information acquisition connector 41, as in the biological information acquisition connector 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 composed of annular grooves respectively formed along the outer circumferences of the two electrode surfaces ES exposed on the second exposed surface S2. The bottom insulator 44 has the same structure as the bottom insulator 14 of the first embodiment except that these lubricant reservoirs 44A are formed.

[0148] In order to obtain biological information of the user via the electrode surface ES, the electrode surface ES is preferably in close contact with the body surface of the user. For example, a medical lubricant may be applied to the body surface of the user to bring the electrode surface ES into contact with the body surface.

[0149] In the connector 41 for acquiring biological information of embodiment 3, a lubricant storage portion 44A consisting of grooves is formed on the 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 body surface of the user, the medical lubricant applied to the body surface of the user is stored inside the lubricant storage portion 44A.

[0150] Furthermore, even when a medical lubricant is not used, moisture such as sweat is stored in the lubricant storage portion 44A and supplied between the electrode surface ES and the user's body surface, thereby maintaining close contact between the electrode surface ES and the user's body surface and acquiring biological information with high precision.

[0151] In addition, the lubricant reservoir 44A in the third embodiment may be applied to the biological information acquiring connector 31 in the second embodiment, and the lubricant reservoir 44A may be formed on the bottom insulator 14 of the biological information acquiring connector 31 .

[0152] Implementation 4

[0153] Fig.26 A living body information acquisition connector 51 according to Embodiment 4 is shown. In the living body information acquisition connector 11 according to Embodiment 1, an adhesive layer 52 is arranged on the second exposed surface S2 of the bottom insulator 14 facing the -Z direction, and the other structures are the same as those of the living body information acquisition connector 11 according to Embodiment 1.

[0154] The adhesive layer 52 is used to adhere the biological information acquiring connector 51 to the user's body surface by utilizing adhesiveness, and the adhesive layer 52 can be formed using, for example, a conventional elastic body including silicone rubber, polyurethane rubber, or the like.

[0155] By bonding the biological information acquiring connector 51 to the body surface of the user using the adhesive layer 52 , the adhesion between the electrode surface ES and the body surface of the user can be improved, and the biological information can be acquired with high accuracy through the electrode surface ES.

[0156] In addition, the adhesive layer 52 in the fourth embodiment may be applied to the biological information acquiring connector 31 in the second embodiment or the biological information acquiring connector 41 in the third embodiment.

[0157] Furthermore, the biological information acquiring connector 11 of Embodiment 1, the bottom insulator 14 of the biological information acquiring connector 31 of Embodiment 2, and the bottom insulator 44 of the biological information acquiring connector 41 of Embodiment 3 may be formed of an insulating material having adhesiveness. As the insulating material having adhesiveness, for example, an elastic body including silicone rubber, polyurethane rubber, etc. may be used.

[0158] If the bottom insulators 14, 44 are formed of an insulating material having such adhesiveness, the biological information acquisition connectors 11, 31, 41 are bonded to the user's body surface, thereby improving the closeness between the electrode surface ES and the user's body surface, and enabling the biological information to be acquired with high precision through the electrode surface ES.

[0159] In addition, for example, the top insulator 13 and the bottom insulator 14 in the biological information acquiring connector 11 of the first embodiment, the biological information acquiring connector 31 of the second embodiment, the biological information acquiring connector 51 of the fourth embodiment, and the top insulator 13 and the bottom insulator 44 in the biological information acquiring connector 41 of the third embodiment may be formed of a flexible insulating material such as an elastomer. If such a top insulator 13 and bottom insulators 14 and 44 are used, the biological information acquiring connectors 11, 31, 41, and 51 can be bent in accordance with the body surface of the user, and the adhesion between the electrode surface ES and the body surface of the user can be further improved.

[0160] In the case of forming a connector for acquiring biological information having a plurality of conductive components 16, 36, it is necessary to increase the area of ​​the top insulator 13 and the bottom insulator 14, 44 along the XY plane according to the number of the conductive components 16, 36. However, by forming the top insulator 13 and the bottom insulator 14, 44 from a flexible insulating material, it is possible to ensure close contact between the electrode surface ES of each conductive component 16, 36 and the user's body surface, thereby acquiring biological information with high precision.

[0161] In addition, the electrode surface ES of each conductive member 16, 36 may be roughened by forming concavities and convexities such as grooves. If such an electrode surface ES is used, water such as medical lubricant and sweat can easily remain on the electrode surface ES, which can improve the adhesion between the electrode surface ES and the user's body surface, thereby obtaining biological information with high accuracy.

[0162] Implementation method 5

[0163] Fig. 27 The biological information acquiring connector 61 according to the fifth embodiment and a piece of clothing cloth 71 to be attached are shown.

[0164] The biological information acquisition connector 61, like the biological information acquisition connector 11 of the first embodiment, includes a top insulator 13 disposed on the surface on the +Z direction side of the reinforcing plate 15, and two plug contacts PC protruding in the +Z direction from a first exposed surface S1 formed by the bottom surface of the recess 13A of the top insulator 13.

[0165] However, the biological information acquiring connector 61 is not held by the cloth 71 of the clothing, and the cloth 71 is disposed apart from the biological information acquiring connector 61 in the −Z direction. In addition, an opening 71A corresponding to the biological information acquiring connector 61 is formed in the cloth 71 .

[0166] like Fig.28 As shown, the connector 61 for acquiring biological information has a bottom insulator 64 arranged on the -Z direction side of the reinforcing sheet 15, and the surface on the +Z direction side of the bottom insulator 64 is in contact with the surface on the -Z direction side of the reinforcing sheet 15 and the surface on the -Z direction side of the top insulator 13, respectively, and the flange portion 16C of the two conductive components 16 is 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.

[0167] In addition, similar to the biological information acquisition connector 11 of embodiment 1, two plug contacts PC and two electrode surfaces ES are formed by two conductive components 16, and the two plug contacts PC protrude from the first exposed surface S1 of the top insulator 13 in the +Z direction, and the two electrode surfaces ES protrude from the second exposed surface S2 of the bottom insulator 64 in the -Z direction.

[0168] like Fig.29 As shown, such a biological information acquisition connector 61 is arranged on a cloth 71 of clothing. The opening 71A of the cloth 71 has a size slightly larger than the bottom insulator 64, the bottom insulator 64 is inserted into the opening 71A, and the reinforcing sheet 15 is in contact with the surface of the cloth 71 around the opening 71A.

[0169] In this state, for example, by sewing the reinforcing sheet 15 to the cloth 71 , the biological information acquiring connector 61 can be attached to the cloth 71 .

[0170] According to the biological information acquiring connector 61 of the fifth embodiment, when assembling the biological information acquiring connector 61, it is not necessary to sandwich the cloth 71 between the top insulator 13 and the bottom insulator 64, and the biological information acquiring connector 61 can be attached to the cloth 71 after assembling.

[0171] Therefore, by attaching the biometric information acquisition connector 61 to ordinary clothes, the clothes can be used as so-called smart clothes that can acquire the user's biometric information just by wearing them. In addition, when the clothes used as smart clothes deteriorate, the biometric information acquisition connector 61 can be reattached to new clothes for reuse.

[0172] In addition, as a method of fixing the reinforcing sheet 15 to the cloth 71, various methods other than sewing, such as bonding, fixing with a zipper, etc., can be adopted.

[0173] In the fifth embodiment, the top insulator 13 and the bottom insulator 64 of the biological information acquisition connector 61 may be formed of a flexible insulating material such as an elastomer, thereby forming a biological information acquisition connector 61 that can be bent to match the user's body surface.

[0174] In the fifth embodiment, the connector for acquiring biological information 61 can be attached to the cloth 71 by fixing the reinforcing sheet 15 after assembling the connector for acquiring biological information 61. Therefore, the top insulator 13, the bottom insulator 64 and the reinforcing sheet 15 can be integrally formed from an insulating material, and the two conductive members 16 can be insert-molded at the same time. In this case, for example, a flexible insulating material such as an elastomer can be used for molding to form a bendable connector for acquiring biological information 61.

[0175] Furthermore, the biological information acquiring connector 31 of the second embodiment, the biological information acquiring connector 41 of the third embodiment, and the biological information acquiring connector 51 of the fourth embodiment can also be similarly configured to be attached to the fabric after the biological information acquiring connector is assembled.
