Description

Technical Field

[0001] The present invention relates to a sheet-like conductive member, and particularly to a sheet-like conductive member that is attached to a connector mounted on an object to be mounted such as clothing and electrically connects a wiring portion of the object to be mounted to a contact of the connector. The present invention also relates to a connector having a sheet-like conductive member, clothing on which the connector is mounted, and a connector mounting method for mounting the connector on the clothing.

Background Art

[0002] In recent years, so-called smart clothing that can acquire biometric information of a user such as a heart rate and body temperature just by wearing it has attracted attention. This smart clothing includes electrodes arranged at measurement locations, and by electrically connecting a wearable device as a measuring device to the electrodes, it becomes possible to transmit biometric information to the wearable device. The connection between the electrode and the wearable device can be made, for example, by using a connector connected to a wiring portion drawn from the electrode.

[0003] As this type of connector, for example, Patent Document 1 discloses a connector 1 as shown in FIG. 21. The connector 1 has a structure in which a plurality of contacts 3 are held by a first insulator 2, and a tab sheet 5, a sheet-like conductive member 6, and a support sheet 7 are sandwiched and held between the first insulator 2 and a second insulator 4. By fixing the tab sheet 5 to the clothing 8, the connector 1 is attached to the clothing 8.

[0004] A notch 6A is formed in the center of the sheet-like conductive member 6, which is used to attach the sheet-like conductive member 6 to the connector 1. On the surface of the sheet-like conductive member 6, one end of multiple flexible conductors 6B is arranged symmetrically on both sides of the notch 6A. One end of these multiple flexible conductors 6B is arranged at the same narrow pitch as the arrangement pitch of the multiple contacts 3 in order to connect to the multiple contacts 3. When the sheet-like conductive member 6 is attached to the connector 1, one end of each flexible conductor 6B is connected to the corresponding contact 3, and the other end of each flexible conductor 6B is connected to a conductive wiring section (not shown) located on the garment 8. As a result, the electrodes of the garment 8 placed at the measurement point are electrically connected to the contacts 3 of the connector 1 via the wiring section and the flexible conductor 6B.

[0005] [Patent Document 1] Japanese Patent Publication No. 2021-61225 [Overview of the project] [Problems that the invention aims to solve]

[0006] When creating a sheet-like conductive member 6 as shown in Figure 21, after forming multiple flexible conductors extending parallel to each other on the sheet body, the central part of each flexible conductor is cut together with the sheet body, thereby simultaneously forming a notch 6A and one end of multiple flexible conductors 6B arranged symmetrically on both sides of the notch 6A. However, if the flexible conductor 6B is formed from conductive threads embroidered or woven into the sheet body, cutting the central portion of multiple conductive threads that extend parallel to each other will result in the cut ends of the conductive threads being located at the edges of the notch 6A. Therefore, if fraying occurs at the cut ends of the conductive threads, when one end of the flexible conductor 6B is brought into contact with a contact 3 for electrical connection, there is a risk that adjacent contacts 3 may short-circuit through the frayed conductive fibers.

[Modes for carrying out the invention]

[0020] Embodiments of this invention will be described below with reference to the attached drawings. Figures 1 and 2 show a connector 11 according to an embodiment. The connector 11 is used as a connector for mating a wearable device, for example, by being attached to clothing (an object to be mounted) having conductive wiring, and has a housing 12 made of an insulating material. The housing 12 holds a plurality of contacts 13, and the housing 12 further holds a tab sheet 14 and a sheet-like conductive member 15 in a state where they are stacked on top of each other. The multiple contacts 13 are arranged in two parallel rows and positioned to protrude perpendicularly from the sheet-like conductive member 15.

[0021] For convenience, the tab sheet 14 and the sheet-like conductive member 15 extend along the XY plane, the direction in which the multiple contacts 13 are arranged is called the Y direction, and the direction in which each of the multiple contacts 13 protrudes is called the +Z direction. The Z direction is the mating direction in which the connector 11 mates with the mating connector.

[0022] Figures 2 and 3 are exploded perspective views of the connector 11. The connector 11 has a first insulator 16 and a second insulator 17, and these first insulator 16 and second insulator 17 constitute the housing 12. Furthermore, each of the multiple contacts 13 is temporarily held by the first insulator 16, and the second insulator 17 is assembled into the first insulator 16 along the Z direction, which is a predetermined assembly direction D1, with the sheet-like conductive member 15 and the tab sheet 14 sandwiched between them. The predetermined assembly direction D1 is the same as the mating direction in which the connector 11 mates with the mating connector.

[0023] The sheet-like conductive member 15 has a sheet body 18 and an embroidered pattern 19 sewn onto the sheet body 18 with embroidery thread. As shown in Figures 2 and 3, the embroidered pattern 19 is visible on both the surface of the sheet-like conductive member 15 in the +Z direction and the back surface in the -Z direction.

[0024] As shown in Figures 4 and 5, the first insulator 16 has a rectangular flat base portion 16A extending along the XY plane, a peripheral wall portion 16B projecting in the +Z direction from the peripheral edge of the base portion 16A, and a plurality of protrusions 16C arranged in two parallel rows, each protruding in the +Z direction from the surface of the base portion 16A inside the peripheral wall portion 16B. A gap 16D is formed between each adjacent protrusion 16C.

[0025] A rectangular recess 16E opening toward the -Z direction is formed on the -Z side of the base portion 16A, and multiple through holes 16F are formed at the bottom of each recess 16E, penetrating from the corresponding gap 16D on the +Z side of the base portion 16A to the recess 16E. The multiple through holes 16F correspond to the multiple contacts 13 and are arranged in two parallel rows.

[0026] Furthermore, at the bottom of the recess 16E, multiple retaining surfaces 16G are formed adjacent to the multiple through holes 16F in the X direction. Each retaining surface 16G extends planarly along the XY plane between the corresponding through hole 16F and the inner wall surface 16H of the recess 16E facing the X direction. The inner wall surface 16H of the recess 16E, facing in the X direction, constitutes a first opposing surface that extends along the Z direction, which is the fitting direction. Furthermore, a plurality of fixing posts 16J protruding in the -Z direction are formed on the -Z side surface of the base portion 16A.

[0027] As shown in Figures 6 and 7, the second insulator 17 has a flat base portion 17A extending along the XY plane, a rectangular parallelepiped-shaped protrusion 17B positioned in the center of the base portion 17A and projecting from the base portion 17A in the +Z direction, and a plurality of columnar members 17C projecting from the protrusion 17B in the +Z direction. The protrusion 17B is inserted into the recess 16E of the first insulator 16 when assembled with the first insulator 16, and is slightly smaller in size than the recess 16E.

[0028] Multiple columnar members 17C correspond to multiple contacts 13 and are arranged in two parallel rows. Furthermore, the base portion 17A has multiple through holes 17D that are arranged around the protrusion 17B and penetrate the base portion 17A in the Z direction. These through holes 17D correspond to multiple fixing posts 16J of the first insulator 16. Furthermore, the outer surface 17E of the protrusion 17B, which faces the X direction, constitutes a second opposing surface that extends along the Z direction, which is the fitting direction.

[0029] Figures 8 and 9 show the configuration of the contacts 13 arranged in the +X direction among the multiple contacts 13 shown in Figures 2 and 3. The contact 13 is a plug-type contact made of a strip-shaped member formed of a conductive material such as metal, and has a U-shaped portion 13A that extends in the Z direction and is bent into a U shape. The U-shaped portion 13A is formed of a pair of extended portions 13B and 13C that extend along the YZ plane and face each other in the X direction, and a top portion 13D that connects the +Z direction ends of the pair of extended portions 13B and 13C to each other. A flat plate portion 13F that extends along the YZ plane is connected to the -Z direction end of the extended portion 13B via a held portion 13E that extends along the XY plane.

[0030] The outer surface of the U-shaped portion 13A forms a contact portion S1 for contacting the contacts of the mating connector, and the -X direction surface of the flat plate portion 13F forms a connection portion S2 for contacting the surface of the sheet-like conductive member 15. When the contact 13 is held in the housing 12 shown in Figures 2 and 3, the contact portion S1 of the contact 13 protrudes from the housing 12 in the +Z direction, and the connecting portion S2 of the contact 13 is located inside the housing 12. Of the multiple contacts 13 shown in Figures 2 and 3, the contacts 13 arranged on the -X direction side have the same configuration as the contacts 13 shown in Figures 8 and 9, but are arranged in the opposite direction with respect to the X direction.

[0031] As shown in Figure 10, the tab sheet 14 is used to attach the connector 11 to clothing by being fixed to the clothing by sewing or the like, and is made of an insulating material such as resin or fabric, and has a size larger than the size of the base 16A of the first insulator 16 and the base 17A of the second insulator 17 in the XY plane.

[0032] A nearly square opening 14A is formed in the center of the tab sheet 14. The portion of the tab sheet 14 located around the opening 14A is sandwiched between the base 16A of the first insulator 16 and the base 17A of the second insulator 17, along with the sheet-like conductive member 15, when the first insulator 16 and the second insulator 17 are assembled together. At this time, the protrusion 17B of the second insulator 17 and a plurality of columnar members 17C are inserted into the opening 14A. Furthermore, multiple through holes 14B are formed around the opening 14A of the tab sheet 14. These through holes 14B correspond to multiple fixing posts 16J of the first insulator 16.

[0033] The sheet-like conductive member 15 is for electrically connecting multiple wiring sections of a garment on which the connector 11 is mounted to multiple contacts 13. As shown in Figure 11, it has a sheet body 18 formed from an insulating fabric or knitted fabric and an embroidered pattern 19 sewn onto the sheet body 18 with embroidery thread. The sheet body 18 is approximately square in shape and extends along the XY plane, and has an H-shaped opening 18A in the center. The opening 18A is used when attaching the sheet-like conductive member 15 to the connector 11, and a pair of protruding pieces 18B are formed in the opening 18A, which are part of the sheet body 18 and project outwards from each other in the X direction within the opening 18A. Furthermore, multiple through holes 18C are formed around the opening 18A of the seat body 18. These through holes 18C correspond to multiple fixing posts 16J of the first insulator 16.

[0034] Of the embroidery threads forming the embroidery pattern 19, conductive threads are used only in the portion exposed on the +Z side surface of the sheet body 18, and insulating threads are used in the portion exposed on the -Z side surface of the sheet body 18, thereby forming the flexible conductor 20 exposed on the +Z side surface of the sheet-like conductive member 15. In other words, the flexible conductor 20 is formed by embroidery using conductive threads. The sheet-like conductive member 15 has a plurality of flexible conductors 20 arranged on the +X side of the opening 18A of the sheet body 18, and a plurality of flexible conductors 20 arranged on the -X side of the opening 18A.

[0035] Each flexible conductor 20 has a first end 20A located near an edge extending along the Y direction of the square-shaped sheet body 18, a second end 20B located on a protruding piece 18B of the sheet body 18, and a connecting portion 20C that connects the first end 20A and the second end 20B to each other. When the connector 11 is mounted on the garment, the first end 20A is connected to the corresponding wiring portion of the garment, and the second end 20B is connected to the corresponding contact 13 of the connector 11. Furthermore, the second ends 20B of the multiple flexible conductors 20 arranged on the +X direction side of the opening 18A of the sheet body 18, and the second ends 20B of the multiple flexible conductors 20 arranged on the -X direction side of the opening 18A of the sheet body 18, are arranged in two rows on both sides of the opening 18A so as to face each other across the opening 18A.

[0036] As shown in Figure 12, in the multiple flexible conductors 20 arranged on the +X side of the opening 18A of the sheet body 18, the multiple first ends 20A are arranged linearly along the Y direction with a first array pitch P1, and the multiple second ends 20B are arranged linearly along the Y direction with a second array pitch P2, parallel to the multiple first ends 20A. The second array pitch P2 of the multiple second ends 20B corresponds to the array pitch of the multiple contacts 13 in the Y direction.

[0037] Here, the first array pitch P1 of the multiple first end portions 20A is set to be greater than the second array pitch P2 of the multiple second end portions 20B. Furthermore, the width W1 in the Y direction of the first end 20A of each flexible conductor 20 is set to be larger than the width W2 in the Y direction of the second end 20B, and the connecting portion 20C has the same width as the second end 20B.

[0038] In other words, the multiple first ends 20A are arranged in the Y direction with a first array pitch P1 that is larger than the array pitch of the multiple contacts 13, and the first ends 20A have a width W1 that is larger than the width W2 of the second ends 20B, while still ensuring a large gap between adjacent first ends 20A in the Y direction. Furthermore, the first end 20A of each flexible conductor 20 has a length L1 in the X direction that is longer than the width W1 in the Y direction.

[0039] Furthermore, the multiple second ends 20B are arranged so as to be separated by a predetermined distance G1 from the tip portion 18D in the X direction of the protruding piece 18B, which forms the edge of the opening 18A of the sheet body 18. For example, as shown in Figure 13, the second end 20B located on the +X direction side of the opening 18A of the sheet body 18 can be formed by embroidered conductive thread that extends in the -X direction from the connection portion with the connecting portion 20C toward the tip portion 18D on the -X direction side of the protruding piece 18B, and is folded back at a position separated by a predetermined distance G1 from the tip portion 18D, and extends in the +X direction toward the connecting portion 20C. As a result, the second end 20B is configured so as not to have a cut end where the conductive thread has been cut.

[0040] Similarly, in the multiple flexible conductors 20 arranged on the -X direction side of the opening 18A of the sheet body 18, the multiple first ends 20A are arranged linearly along the Y direction with a first arrangement pitch P1, and the multiple second ends 20B are arranged linearly along the Y direction with a second arrangement pitch P2, parallel to the multiple first ends 20A. Furthermore, in the case of the multiple flexible conductors 20 arranged on the -X direction side of the opening 18A of the sheet body 18, similarly, the first end 20A of each flexible conductor 20 has a Y-direction width W1 that is greater than the Y-direction width W2 of the second end 20B, the connecting portion 20C has the same width as the second end 20B, and the first end 20A has an X-direction length L1 that is longer than the Y-direction width W1.

[0041] Furthermore, the second end 20B of the flexible conductor 20 located on the -X side of the opening 18A of the sheet body 18 is also positioned to be separated from the X-direction tip 18D of the corresponding protruding piece 18B by a predetermined distance G1, similar to the second end 20B of the flexible conductor 20 located on the +X side of the opening 18A of the sheet body 18. The second end 20B of the flexible conductor 20 located on the -X side of the opening 18A of the sheet body 18 can also be embroidered so as to be folded back at a position separated from the X-direction tip 18D of the protruding piece 18B by a predetermined distance G1, so as not to have a cut end where the conductive thread has been cut.

[0042] When assembling the connector 11, the multiple contacts 13 are first pushed into the first insulator 16 from the -Z direction towards the +Z direction, thereby temporarily holding the multiple contacts 13 in the first insulator 16. At this time, the U-shaped portion 13A of each contact 13 is inserted from the recess 16E on the -Z side of the first insulator 16 through the corresponding through hole 16F into the gap 16D formed between adjacent protrusions 16C, and the contact portion S1 formed by the outer surface of the U-shaped portion 13A is exposed on the +Z side of the first insulator 16.

[0043] Furthermore, the flat plate portion 13F that forms the connection portion S2 with the held portion 13E of the multiple contacts 13 is located within the recess 16E of the first insulator 16, and the flat plate portion 13F is in contact with the inner wall surface 16H of the recess 16E of the first insulator 16.

[0044] Here, the multiple fixing posts 16J of the first insulator 16 are sequentially passed through the multiple through holes 14B of the tab sheet 14 and the multiple through holes 18C of the sheet-like conductive member 15, thereby positioning the tab sheet 14 and the sheet-like conductive member 15 on the -Z side of the first insulator 16. Furthermore, the multiple fixing posts 16J of the first insulator 16 are passed through the multiple through holes 17D of the second insulator 17, moving the second insulator 17 toward the first insulator 16 in the +Z direction, and the assembly into the first insulator 16 begins.

[0045] At this time, each of the columnar members 17C of the second insulator 17 is inserted into the inside of the U-shaped portion 13A of the corresponding contact 13 from the -Z direction. Furthermore, the protrusion 17B of the second insulator 17 is sequentially passed through the opening 18A of the sheet-like conductive member 15 and the opening 14A of the tab sheet 14 from the -Z direction, and then inserted into the recess 16E of the first insulator 16. At this time, the pair of protruding pieces 18B positioned inside the opening 18A of the sheet-like conductive member 15 are pushed by the protrusion 17B of the second insulator 17 and bent in the +Z direction, and then fit between the flat plate portion 13F of the contact 13, which is in contact with the inner wall surface 16H of the recess 16E of the first insulator 16, and the outer surface 17E of the protrusion 17B of the second insulator 17.

[0046] If the second insulator 17 is moved toward the first insulator 16 in the +Z direction, as shown in Figure 14, the held portions 13E of the multiple contacts 13 are sandwiched between the +Z-direction side surface of the convex portion 17B of the second insulator 17 and the holding surface 16G within the recess 16E of the first insulator 16. As a result, the multiple contacts 13 are held by the first insulator 16 and the second insulator 17.

[0047] Furthermore, the protruding piece 18B of the sheet body 18 of the sheet-like conductive member 15 is pressed by the convex portion 17B of the second insulator 17 and bent in the +Z direction, and is sandwiched between the inner wall surface 16H of the recess 16E of the first insulator 16 which constitutes the first opposing surface and the outer surface 17E of the convex portion 17B of the second insulator 17 which constitutes the second opposing surface. The second end portion 20B of the flexible conductor 20 exposed on the surface of the protruding piece 18B contacts the connection portion S2 of the flat plate portion 13F of the contact 13 which is in contact with the inner wall surface 16H of the recess 16E of the first insulator 16 with a predetermined contact pressure. As a result, the contact 13 is electrically connected to the corresponding second end portion 20B of the flexible conductor 20 of the sheet-like conductive member 15.

[0048] As described above, the second end 20B of the flexible conductor 20, which is positioned on the protruding piece 18B of the sheet-like conductive member 15, is positioned so as to be separated from the tip 18D of the protruding piece 18B by a predetermined distance G1. Therefore, even if fraying occurs at the tip of the second end 20B of the conductive thread, the adjacent contacts 13 are less likely to short-circuit. Furthermore, as shown in Figure 13, if the second end 20B of the flexible conductor 20 is embroidered so as to be folded back at a predetermined distance G1 between it and the tip 18D of the protruding piece 18B, and does not have a cut end where the conductive thread has been cut, then when the second ends 20B of multiple flexible conductors 20 contact the connection portion S2 of multiple contacts 13 with a predetermined contact pressure, the adjacent contacts 13 will not short-circuit through the frayed conductive fibers at the cut end of the conductive thread. Therefore, it becomes possible to reliably electrically connect the second ends 20B of multiple flexible conductors 20 to multiple contacts 13.

[0049] Furthermore, the multiple fixing posts 16J of the first insulator 16 protrude through the corresponding through holes 17D of the second insulator 17 and outward from the -Z direction side of the second insulator 17. The second insulator 17 is fixed to the first insulator 16 by the heat deformation of the -Z end of the fixing post 16J of the first insulator 16 that protrudes from the -Z side of the second insulator 17. This completes the assembly of the connector 11 shown in Figure 1.

[0050] Next, we will explain how to implement the connector 11 into the garment 31. As shown in Figure 15, the garment 31 has two slits 32 formed in the area where the connector 11 is to be attached. The two slits 32 are spaced apart in the X direction, parallel to each other, and extend in the Y direction, penetrating from the front to the back of the garment 31. Each of the two slits 32 has a length in the Y direction that is slightly longer than the Y direction length of the sheet-like conductive member 15 of the connector 11, and is spaced apart in the X direction from each other by a distance that is slightly longer than the X direction length of the housing 12 of the connector 11.

[0051] After aligning the connector 11 with the +Z direction side of the two slits 32 of the garment 31, the sheet-like conductive member 15 located on the +X direction side of the housing 12 and the portion located on the -X direction side of the housing 12 are passed through the corresponding slits 32, respectively, and pulled out from the front side to the back side of the garment 31. As shown in Figure 16, on the back surface of the garment 31 facing the -Z direction, multiple conductive wiring portions 33 are formed, extending in the +X and -X directions, respectively, perpendicular to the two slits 32. One end of each of these wiring portions 33 is arranged in the Y direction at the same arrangement pitch as the multiple first ends 20A of the sheet-like conductive member 15, near the corresponding slits 32, and has approximately the same width in the Y direction as the first ends 20A.

[0052] The multiple wiring sections 33 are formed, for example, by conductive threads sewn into the garment 31, and at least the surface facing the -Z direction is conductive. The other ends of the multiple wiring sections 33 extend along the back surface of the garment 31 to electrodes (not shown) attached to the garment 31. The +X-direction portion and the -X-direction portion of the sheet-like conductive member 15, which are pulled out through the two slits 32 of the garment 31 to the back side of the garment 31 facing the -Z direction, are arranged to overlap one end of a plurality of wiring sections 33.

[0053] Since one end of the wiring section 33 is arranged in the Y direction with the same arrangement pitch as the multiple first ends 20A of the sheet-like conductive member 15, in this case, as shown in Figure 17, the multiple first ends 20A of the sheet-like conductive member 15 each overlap the corresponding wiring section 33 of the garment 31 on the -Z direction side. Therefore, by sewing the garment 31 and the sheet-like conductive member 15 together using suture thread 41, the multiple first ends 20A of the sheet-like conductive member 15 can be electrically connected to the multiple wiring portions 33 of the garment 31, respectively. In Figure 17, the garment 31 and the sheet-like conductive member 15 are sewn together using suture thread 41 in a so-called "running stitch" or "straight stitch," but this is not the only way to do so.

[0054] As shown in Figure 12, the width W1 in the Y direction of the first end 20A of the sheet-like conductive member 15 is set to be larger than the width W2 in the Y direction of the second end 20B, and the wiring portion 33 of the garment 31 has approximately the same width in the Y direction as the first end 20A. Therefore, a large contact area can be secured between the first end 20A and the wiring section 33, making it possible to electrically connect the first end 20A to the wiring section 33 with high reliability.

[0055] Furthermore, since the width W1 in the Y direction of the first end 20A of the sheet-like conductive member 15 is greater than the width W2 in the Y direction of the second end 20B, and the wiring portion 33 of the garment 31 has approximately the same width in the Y direction as the first end 20A, even if a slight misalignment in the Y direction occurs between the first end 20A of the sheet-like conductive member 15 and the wiring portion 33 of the garment 31 due to manufacturing tolerances, etc., the contact area between the first end 20A and the wiring portion 33 can be secured, ensuring a reliable electrical connection. Furthermore, the tab sheet 14 of the connector 11 can also be sewn to the garment 31 using suture thread 41, thereby securing the connector 11 to the garment 31.

[0056] As shown in Figure 17, the first end portion 20A of the sheet-like conductive member 15 and the wiring portion 33 of the garment 31 overlap in the Z direction and are in direct contact with each other. Therefore, the suture thread 41 used for sewing may be an insulating thread or a conductive thread. However, if insulating thread is used as the suture thread 41, the suture thread 41 can be used to sew together multiple first ends 20A of the sheet-like conductive member 15 and multiple wiring portions 33 of the garment 31.

[0057] In the above embodiment, the sheet-like conductive member 15 located on the +X side of the housing 12 and the portion located on the -X side of the housing 12 are each passed through the corresponding slits 32 of the garment 31, thereby being pulled out from the front side to the back side of the garment 31. However, the embodiment is not limited to this. For example, the connector 11 shown in Figure 15 can be placed directly on the surface of the garment 31 facing the +Z direction, and the connector 11 can be mounted on the garment 31 without pulling out a portion of the sheet-like conductive member 15 to the back side of the garment 31.

[0058] At this time, if the corresponding first end 20A of the sheet-like conductive member 15 is positioned directly above the wiring portion 33 located on the back surface of the garment 31, then, as shown in Figure 18, the first end 20A will be located on the +Z side of the wiring portion 33 via the sheet body 18 of the sheet-like conductive member 15 and the garment 31. Therefore, by using conductive suture thread 42 to sew from the first end 20A through the sheet body 18 and the clothing 31 to the wiring section 33, the first end 20A and the wiring section 33 can be electrically connected via the suture thread 42.

[0059] For example, by reducing the size of the stitches of the suture thread 42 within the first end portion 20A and increasing the number of suture threads 42 that penetrate the first end portion 20A and the wiring portion 33, the cross-sectional area of ​​the conductive path between the first end portion 20A and the wiring portion 33 can be increased, thereby achieving a highly reliable electrical connection. Furthermore, when using conductive sutures 42, in order to prevent short circuits between the multiple first ends 20A, it is necessary to suture each of the multiple first ends 20A to the corresponding wiring section 33 using separate sutures 42.

[0060] Figure 19 shows a mating connector 51 that is mated to the connector 11 according to the embodiment. The mating connector 51 has a housing 52 made of an insulating material, and a plurality of contacts 53 are held in the housing 52. The multiple contacts 53 correspond to the multiple contacts 13 of the connector 11 and are arranged in two parallel rows with the same arrangement pitch as the multiple contacts 13. Each contact 53 is oriented in the -Z direction and is a receptacle-type contact corresponding to the plug-type contact 13 of the connector 11.

[0061] The housing 52 has a circumferential groove 52A oriented in the -Z direction that surrounds the multiple contacts 53. The circumferential groove 52A corresponds to the peripheral wall portion 16B of the first insulator 16 of the connector 11. As shown in Figure 20, the mating connector 51 has a first insulator 54 and a second insulator 55, and these first insulator 54 and second insulator 55 constitute the housing 52. Multiple contacts 53 are held by the second insulator 55, and a circumferential groove 52A is also formed in the second insulator 55.

[0062] The mating connector 51 further includes a circuit board 56 and a plurality of fixing screws 57 for fixing the circuit board 56 to the first insulator 54. The mating connector 51 is assembled when the plurality of contacts 53 held by the second insulator 55 are connected to the plurality of connection pads 56A of the circuit board 56 by soldering or the like, and the circuit board 56 is fixed to the first insulator 54 by the plurality of fixing screws 57. On the surface of the circuit board 56, which faces the +Z direction opposite to the housing 52, are mounted wireless transmission circuits and the like (not shown) connected to multiple contacts 53.

[0063] When such a mating connector 51 is mated with the connector 11 mounted on the garment 31 in a position where multiple contacts 53 are oriented in the -Z direction, multiple plug-type contacts 13 of the connector 11 are inserted into multiple receptacle-type contacts 53 of the mating connector 51, and an electrical connection is made. In addition, the peripheral wall portion 16B of the first insulator 16 of the connector 11 is inserted into the peripheral groove 52A of the housing 52 of the mating connector 51, and the mating connector 51 is held in place relative to the connector 11.

[0064] As a result, the user's biometric information, such as heart rate and body temperature, acquired using electrodes attached to the garment 31, is input to a wireless transmission circuit mounted on the circuit board 56 via the wiring section 33 of the garment 31, the flexible conductor 20 and contact 13 of the sheet-like conductive member 15 of the connector 11, and the contact 53 of the mating connector 51. From there, the wireless transmission circuit can wirelessly transmit the information to a tablet terminal or a stationary measuring device.

[0065] In the connector 11 according to the above-described embodiment, the multiple contacts 13 are arranged in two parallel rows, but this is not the only arrangement; they may be arranged in a single row. Furthermore, this invention does not necessarily require multiple contacts 13; it is sufficient to have at least one contact 13.

[0066] In the above embodiment, as shown in Figure 14, the flexible conductor 20 of the sheet-like conductive member 15 is exposed on the +Z-direction surface of the sheet body 18, the flat portion 13F of the contact 13 contacts the inner wall surface 16H of the recess 16E of the first insulator 16, and the protruding piece 18B of the sheet-like conductive member 15 is sandwiched between the flat portion 13F of the contact 13 and the outer surface surface 17E of the convex portion 17B of the second insulator 17, with the second end portion 20B of the flexible conductor 20 exposed on the surface of the protruding piece 18B being electrically connected to the contact 13, but the embodiment is not limited to this.

[0067] The flexible conductor 20 of the sheet-like conductive member 15 may be exposed on the -Z-direction side surface of the sheet body 18. In this case, the flat portion 13F of the contact 13 is positioned to contact the outer surface 17E of the convex portion 17B of the second insulator 17, and the protruding piece 18B of the sheet-like conductive member 15 is sandwiched between the flat portion 13F of the contact 13 and the inner wall surface 16H of the recess 16E of the first insulator 16. The second end 20B of the flexible conductor 20 exposed on the surface of the protruding piece 18B is electrically connected to the flat portion 13F of the contact 13.

[0068] Furthermore, as the sheet-like conductive member 15 of the connector 11, both the portion exposed on the +Z direction surface and the portion exposed on the -Z direction surface of the sheet body 18 can be formed by embroidery using conductive thread, thereby exposing the flexible conductor 20 on both sides of the sheet body 18. Furthermore, in the above embodiment, the flexible conductor 20 of the sheet-like conductive member 15 is formed from conductive threads embroidered on the sheet body 18. However, the invention is not limited to this, and the flexible conductor 20 can also be formed by knitting conductive threads into the sheet body 18, which is made of an insulating fabric or knitted fabric.

[0069] In the connector 11 according to the above embodiment, a tab sheet 14 is placed between the housing 12 and the sheet-like conductive member 15. However, the tab sheet 14 may be omitted, especially when there is no need to reinforce the mounting area when mounting the connector 11 to the garment 31. Furthermore, in the above embodiment, the connector 11 is mounted on the garment 31, which is the object to be mounted. However, the object to be mounted is not limited to the garment 31. For example, the connector 11 can also be mounted on bags that the user carries or wears, seats on which the user rests, beds, bedding, etc. [Explanation of Symbols]
