The present invention relates to a slide connector, particularly to a slide connector that is connected to a wearable device.
In recent years, so-called wearable devices in which terminal devices such as various sensors and communication devices operate as being worn by a user have attracted attention. Such a wearable device is electrically connected to a device like a measuring device or a power source to transmit detected information or receive power supply. While electrical connection can be established via a connector attached to a garment, the connection via the connector has to be disconnected when the wearable device is detached, when the garment is washed, and on other occasions.
To cope with it, for instance, a snap button connector has been used to establish connection between devices as disclosed in JP 2015-135723 A.
As shown in
Electrical connection of a wearable device can be made using the snap button connector as above, and when the wearable device is detached or the garment is washed for example, the electrical connection via the snap button connector can be disconnected by separating the male snap button 2 from the female snap button 4.
In the snap button connector of JP 2015-135723 A, however, since the entire male snap button 2 and the entire female snap button 4 each function as a single electrode, connections of a plurality of wires would require attachment of as many snap button connectors as the number of the wires to a garment, which hampers miniaturization of a wearable device.
Aside from that, while the connector needs to be thin because it electrically connects the first cloth 1 to the second cloth 3, the snap button connector of JP 2015-135723 A has the configuration in which the convex portion 5 of the male snap button 2 is fitted in the concave portion 6 of the female snap button 4 in the direction orthogonal to a surface of the garment, and this is disadvantageous from the standpoint of reducing the connector in thickness.
Further, in electrically connecting the first cloth 1 to the second cloth 3, it is necessary to firmly push either the male snap button 2 or the female snap button 4 down to the wearer's body from above the garment, and this should be a burden on the body.
In addition, the snap button connector of JP 2015-135723 A does not have waterproof structure even though it is a connector to be attached to a garment in use, and thus water may enter the contact portion between the convex portion 5 of the male snap button 2 and the concave portion 6 of the female snap button 4. Accordingly, there is a problem in that, even if the connector is only slightly exposed to water in a living environment, an attached water drop easily causes a short-circuit at the contact portion.
The present invention has been made in order to solve the conventional drawbacks described above and is aimed at providing a slide connector that enables a small and thin wearable device to be achieved, reduces a burden on a wearer's body in a connecting process and prevents water from entering.
A slide connector according to the present invention comprises:
a garment-side connector portion to be attached to a garment; and
a module-side connector portion to be fitted with the garment-side connector portion in a fitting plane,
wherein the garment-side connector portion includes a garment-side connector body extending along the fitting plane, a plurality of first contacts in a plate shape that are disposed in the garment-side connector body and that individually have contact surfaces parallel to the fitting plane, and a locking portion provided in the garment-side connector body and having a locking surface,
wherein the module-side connector portion includes a module-side connector body extending along the fitting plane, a plurality of second contacts of spring type that are disposed in the module-side connector body, that correspond to the first contacts of the garment-side connector portion and that individually have contact portions displaceable in a direction orthogonal to the fitting plane, and a portion to be locked provided on the module-side connector body,
wherein one of the garment-side connector portion and the module-side connector portion has a waterproof member that is located in the fitting plane, has a closed shape surrounding the contact surfaces of the first contacts or the second contacts and is elastically deformable, and
wherein, when the module-side connector portion is overlapped on the garment-side connector portion and slid along the fitting plane from a first position to a second position, each of the contact portions of the second contacts comes into contact with a corresponding one of the contact surfaces of the first contacts to establish electrical connection, the portion to be locked comes into contact with the locking surface of the locking portion whereby the module-side connector portion is fitted with the garment-side connector portion, and the waterproof member is elastically compressed to thereby prevent water from entering portions at which the contact surfaces of the first contacts and the contact portions of the second contacts are in contact with each other.
Embodiments of the present invention are described below based on the appended drawings.
Embodiment 1
As shown in
The garment-side connector body 12 is composed of a base member 15 of disk shape and a frame member 16. A surface of the base member 15 forms a garment-side reference surface 15A, and the frame member 16 is attached to the outer edge of the garment-side reference surface 15A. The frame member 16 has a circular frame shape with an opening 17 provided at its center. The first contacts 13 each have a contact surface 13C that is exposed on the garment-side reference surface 15A of the base member 15 through the opening 17 of the frame member 16. The first contacts 13 are not exposed on a bottom surface 15B of the base member 15.
The locking portions 14 are located closer to the outer edge of the garment-side connector portion 11 than the contact surfaces 13C of the first contacts 13 exposed on the garment-side reference surface 15A of the base member 15 are, and arranged in a circumferential direction along the inner peripheral edge of the frame member 16.
The first waterproof member W1 is disposed on the garment-side reference surface 15A of the base member 15 to be exposed through the opening 17 of the frame member 16 and has a closed shape surrounding the contact surfaces 13C of the first contacts 13.
The base member 15 is shown in
The circumferentially extending portion 13A as above is connected at its other end with the radially extending portion 13B. The radially extending portion 13B extends from the other end of the circumferentially extending portion 13A along the radial direction of the base member 15 and is provided with an external connection portion 13F in a bending shape.
As shown in
As shown in
As shown in
The base member 15 configured as above can be formed integrally with the first contacts 13 and the first waterproof member W1 using, for instance, an insulating resin.
For example, firstly, insert-molding is carried out using the first contacts 13 connected to a carrier CR as shown in
After the base member 15 is thus shaped, a rubber compound obtained by mixing raw rubber and a compounding agent is poured into the groove 18 using a mold different from a mold used in insert-molding and then vulcanized, thereby manufacturing the elastic first waterproof member W1.
Thereafter, the first contacts 13 are separated from the carrier CR, thus manufacturing the base member 15 shown in
Instead of pouring the rubber compound into the groove 18 using a mold, the first waterproof member W1 previously formed in an annular shape may be mechanically fixed in the groove 18.
As shown in
In the frame member 16, a guide surface 20A is formed in a position adjacent to each notch 19 in the circumferential direction, and a locking surface 20B is formed in a position adjacent to each guide surface 20A in the circumferential direction. The locking surfaces 20B are arranged in the circumferential direction along the inner peripheral edge of the frame member 16, lie in parallel to the flat bottom surface 16B of the frame member 16 and closer to the top surface 16A of the frame member 16 than the bottom surface 16B thereof, and face the bottom surface 16B of the frame member 16. Each guide surface 20A is continuous with the locking surface 20B and is inclined so as to get closer to the bottom surface 16B of the frame member 16 as advancing from the adjacent notch 19 to the locking surface 20B.
The bottom surface 16B of the frame member 16 has therein a plurality of fitting holes 21 corresponding to the external connection portions 13F of the first contacts 13 projecting from the garment-side reference surface 15A of the base member 15.
As shown in
The wiring members 22 correspond to the first contacts 13 and are connected to a wearable device (not shown) attached to the garment. The wiring members 22 are composed of, for instance, conductive fibers. The wiring members 22 are arranged such that, when the wiring members 22 are brought into contact with the garment-side reference surface 15A of the base member 15, one end of each wiring member 22 overlaps the corresponding external connection portion 13F of the base member 15. In the upper cloth 23, an opening 25 slightly larger than the opening 17 of the frame member 16 is formed in advance.
The base member 15 is disposed between the lower cloth 24 and the wiring members 22 such that the external connection portions 13F of the base member 15 come into contact with one ends of the corresponding wiring members 22, the frame member 16 is aligned with the base member 15, and the frame member 16 is firmly pressed against the base member 15. As a result, the external connection portions 13F of the base member 15 are fitted into the fitting holes 21 of the frame member 16 with the wiring members 22 being sandwiched, and thus the garment-side connector portion 11 is attached to the garment.
In this process, the wiring members 22 are pressed into the corresponding fitting holes 21 of the frame member 16 while being in contact with the corresponding external connection portions 13F of the base member 15 and thus electrically connected to the external connection portions 13F.
Since the base member 15 and the frame member 16 are combined to be integral with each other, the locking surfaces 20B of the frame member 16 face the garment-side reference surface 15A of the base member 15, and the locking portions 14 are formed between the locking surfaces 20B of the frame member 16 and the garment-side reference surface 15A of the base member 15.
The module-side connector portion 31 is shown in
The second contacts 33 are arranged to form a circle in the circumferential direction of the module-side connector body 32 so as to correspond to the first contacts 13 of the garment-side connector portion 11.
The module-side connector body 32 includes an annular module case 35 and a disk-shaped lid portion 36 attached to the module case 35.
The annular module case 35 has a flat bottom surface facing in the opposite direction from the lid portion 36, and this bottom surface of the module case 35 forms a module-side reference surface 35A. The module case 35 has therein a plurality of through-holes 35B that correspond to the second contacts 33 and open at the module-side reference surface 35A, and the second contacts 33 are exposed through the corresponding through-holes 35B. The portions to be locked 34 are formed on the outer peripheral portion of the module case 35.
As shown in
The module case 35 further includes a plurality of partition wall portions 35G extending in the radial direction between the outer wall portion 35C and the inner wall portion 35D. The outer wall portion 35C, the inner wall portion 35D and the partition wall portions 35G constitute second contact accommodating spaces 35H arranged in the circumferential direction so as to correspond to the through-holes 35B.
The upper surfaces of the annular step portions 35E and 35F and partition wall portions 35G form the same plane.
As shown in
The waterproof rubber ring 38 is in the shape corresponding to the upper surfaces of the annular step portions 35E and 35F and partition wall portions 35G of the module case 35 and has a plurality of openings 38A corresponding to the second contact accommodating spaces 35H of the module case 35.
The second contacts 33 mounted on the substrate 37 are accommodated in the second contact accommodating spaces 35H of the module case 35 through the openings 38A of the waterproof rubber ring 38.
As shown in
When the lid portion 36 is attached to the module case 35, the waterproof rubber ring 38 is sandwiched between the substrate 37 and the upper surfaces of the annular step portions 35E and 35F and partition wall portions 35G of the module case 35 and elastically compressed, and consequently, the second contacts 33 are separated from each other, which prevents any adjacent two of the second contacts 33 from short-circuiting due to exposure to water. Since the contact portions 33A of the second contacts 33 are exposed, the contact portions 33A are not prevented from coming into contact with water; however, it is possible to prevent a short-circuit between adjacent two second contacts 33 that may cause a failure and draining of a battery.
The portions to be locked 34 are formed in positions corresponding to the notches 19 of the garment-side connector portion 11, that is, so as not to have rotational symmetry with respect to the circumferential direction of the module case 35, and are disposed closer to the outer edge of the module-side connector portion 31 than the contact portions 33A of the second contacts 33 are.
The upper surface of the lid portion 36 is provided with a tab 36A used to rotate the module-side connector portion 31 relative to the garment-side connector portion 11.
The first contacts 13 of the garment-side connector portion 11 may be made of, for instance, stainless steel or nickel silver (alloy of copper, zinc and nickel), while the second contacts 33 of the module-side connector portion 31 may be made of, for instance, nickel silver or copper. The substrate 37 on which the second contacts 33 are mounted may carry, for instance, a circuit module connected to the wearable device (not shown) attached to the garment.
In the garment-side connector portion 11, the first contacts 13, the locking portions 14, the opening 17 of the frame member 16, the notches 19 and the first waterproof member W1 are concentrically arranged, while in the module-side connector portion 31, likewise, the circular outer edge of the module-side connector body 32, the second contacts 33 and the portions to be locked 34 are concentrically arranged. A circle along which the contact surfaces 13C of the first contacts 13 of the garment-side connector portion 11 are arranged is set to be the same in radius as a circle along which the contact portions 33A of the second contacts 33 of the module-side connector portion 31 are arranged.
The slide connector is configured such that the module-side connector portion 31 is, while being inserted in the opening 17 of the frame member 16 of the garment-side connector portion 11, rotatable and slidable about the center of the concentric circle of the garment-side connector portion 11.
In a process for fitting the module-side connector portion 31 to the garment-side connector portion 11, firstly, the module-side connector portion 31 is overlapped on and aligned with the garment-side connector portion 11 such that the portions to be locked 34 of the module-side connector portion 31 are located directly above the corresponding notches 19 of the garment-side connector portion 11, and as shown in
At this time, as shown in
As shown in
At this time, the module-side reference surface 35A of the module-side connector portion 31 is in contact with the first waterproof member W1 projecting above the garment-side reference surface 15A of the garment-side connector portion 11.
The garment-side reference surface 15A of the garment-side connector portion 11 and the module-side reference surface 35A of the module-side connector portion 31 form a fitting plane at the time when the garment-side connector portion 11 and the module-side connector portion 31 are fitted with each other.
The rotational position of the module-side connector portion 31 when the portions to be locked 34 of the module-side connector portion 31 are inserted in the notches 19 of the garment-side connector portion 11 in this manner is defined as a first position P1, which is shown in
From the state where the module-side connector portion 31 is in the first position P1, the tab 36A of the module-side connector portion 31 is operated to rotate and slide the module-side connector portion 31 relative to the garment-side connector portion 11 along the fitting plane, whereby the contact portions 33A of the spring-like second contacts 33 of the module-side connector portion 31 move from directly above the flat surfaces 13E of the first contacts 13 of the garment-side connector portion 11 to come into contact with the inclined surfaces 13D of the first contacts 13 and gradually elastically deform.
When the tab 36A of the module-side connector portion 31 is further operated to rotate and slide the module-side connector portion 31 to a second position P2 shown in
When the module-side connector portion 31 is rotated and slid from the first position P1 to the second position P2, firstly, each portion to be locked 34 of the module-side connector portion 31 comes into contact with the corresponding guide surface 20A of the garment-side connector portion 11. Since the guide surface 20A is inclined so as to get closer to the bottom surface 16B of the frame member 16 as advancing from the notch 19 to the locking surface 20B, the portion to be locked 34 is to receive an increasing force acting toward the base member 15 from the guide surface 20A, so that the module-side connector portion 31 is pressed against the garment-side reference surface 15A of the garment-side connector portion 11. Consequently, the first waterproof member W1 of the garment-side connector portion 11 is pressed and compressed by the module-side reference surface 35A of the module-side connector portion 31.
When the module-side connector portion 31 is in the position P2, as shown in
When the garment-side connector portion 11 and the module-side connector portion 31 are fitted with each other, the first waterproof member W1 of the garment-side connector portion 11 is compressed, and accordingly, the portions to be locked 34 of the module-side connector portion 31 are pressed against the locking surfaces 20B due to a reaction force generated upon elastic deformation of the first waterproof member W1, which allows the fitted state between the garment-side connector portion 11 and the module-side connector portion 31 to be locked.
The fitted state between the garment-side connector portion 11 and the module-side connector portion 31 can be released by pressing the module-side connector portion 31 against the garment-side connector portion 11 and rotating and sliding the module-side connector portion 31 to the first position P1.
Since the notches 19 of the garment-side connector portion 11 and the portions to be locked 34 of the module-side connector portion 31 are arranged so as not to have rotational symmetry with respect to the circumferential direction, the module-side connector portion 31 is fitted with the garment-side connector portion 11 always in a defined rotational position, thus preventing fitting in a wrong rotational position.
As described above, simply by overlapping the module-side connector portion 31 on the garment-side connector portion 11 and rotating and sliding the module-side connector portion 31 from the first position P1 to the second position P2 along the fitting plane, the contact portions 33A of the spring-like second contacts 33 of the module-side connector portion 31 come into contact with the corresponding contact surfaces 13C of the plate-shaped first contacts 13 of the garment-side connector portion 11 to thereby establish electrical connection therebetween, and the portions to be locked 34 of the module-side connector portion 31 come into contact with the locking surfaces 20B of the corresponding locking portions 14 of the garment-side connector portion 11 whereby the module-side connector portion 31 can be fitted to the garment-side connector portion 11. As a result, a small and thin wearable device is obtained, and since it is not necessary to firmly press a snap button against a wearer's body from above the garment as required in a conventional snap button connector, a burden applied on a wearer's body is reduced at the time of connecting the connector.
Since the first contacts 13 of the garment-side connector portion 11 each have the inclined surface 13D continuous with the contact surface 13C, the corresponding second contact 33 of the module-side connector portion 31 comes into contact with the contact surface 13C of the first contact 13 of the garment-side connector portion 11 as wiping the inclined surface 13D thereof in the fitting process between the garment-side connector portion 11 and the module-side connector portion 31. This configuration enables to effectively prevent poor electrical connection between the first contacts 13 and the second contacts 33, which may be caused due to foreign matter present therebetween.
Since the elastically-deformable first waterproof member W1 having a closed shape surrounding the contact surfaces 13C of the first contacts 13 is disposed on the garment-side reference surface 15A of the garment-side connector portion 11, the first waterproof member W1 is compressed in the fitting process between the garment-side connector portion 11 and the module-side connector portion 31, whereby water is prevented from entering the portions at which the contact surfaces 13C of the first contacts 13 of the garment-side connector portion 11 and the contact portions 33A of the second contacts 33 of the module-side connector portion 31 are in contact with each other.
Since the frame member 16 of the garment-side connector portion 11 has the guide surfaces 20A inclined and continuous with the associated locking surfaces 20B, when the module-side connector portion 31 is rotated and slid from the first position P1 to the second position P2, an increasing force is applied from each guide surface 20A to the corresponding portion to be locked 34 of the module-side connector portion 31 to press the module-side connector portion 31 against the garment-side reference surface 15A of the garment-side connector portion 11, thereby compressing the first waterproof member W1 of the garment-side connector portion 11. Thus a waterproof effect is effectively obtained through the first waterproof member W1.
While the frame member 16 of the garment-side connector portion 11 has the guide surfaces 20A continuous with the associated locking surfaces 20B, locking surfaces inclined to the garment-side reference surface 15A, which is to be a fitting plane, may be disposed adjacent to the notches 19 instead. Even with this configuration, the fitted state between the garment-side connector portion 11 and the module-side connector portion 31 is locked, and the first waterproof member W1 is compressed, so that water is prevented from entering the portions at which the contact surfaces 13C of the first contacts 13 of the garment-side connector portion 11 and the contact portions 33A of the second contacts 33 of the module-side connector portion 31 are in contact with each other.
Embodiment 2
In Embodiment 1 above, the contact portions 33A of the spring-like second contacts 33 of the module-side connector portion 31 project from the module-side reference surface 35A, and correspondingly, the contact surfaces 13C of the first contacts 13 of the garment-side connector portion 11 have a substantially same height as the garment-side reference surface 15A of the base member 15 while the flat surfaces 13E are located lower than the garment-side reference surface 15A of the base member 15 to be closer to the bottom surface 15B; however, the invention is not limited thereto.
As shown in
Except for the base member 45 and the first contacts 43 as above, the garment-side connector portion 41 has the same configuration as the garment-side connector portion 11 in Embodiment 1.
The module-side connector portion 51 of the slide connector according to Embodiment 2 has an annular module case 55, and the bottom surface of the module case 55 forms a module-side reference surface 55A, as shown in
Except for the fact that the module case 55 has the groove G as well as the positioning height of the second contacts 33 with respect to the module case 55, the module-side connector portion 51 has the same configuration as the module-side connector portion 31 in Embodiment 1.
In a process for fitting the module-side connector portion 51 to the garment-side connector portion 41, firstly, the module-side connector portion 51 is overlapped on and aligned with the garment-side connector portion 41. At this time, as shown in
As shown in
At this time, the module-side reference surface 55A of the module-side connector portion 51 is in contact with the first waterproof member W1 projecting above the garment-side reference surface 45A of the garment-side connector portion 41.
When the module-side connector portion 51 is rotated and slid relative to the garment-side connector portion 41 along the fitting plane, the contact portions 33A of the spring-like second contacts 33 of the module-side connector portion 51 come into contact with the inclined surfaces 13D of the first contacts 43 of the garment-side connector portion 41 and gradually elastically deform.
When the module-side connector portion 51 is further rotated and slid, as shown in
With rotation and slide of the module-side connector portion 51, the portions to be locked 34 of the module-side connector portion 51 receive a force acting toward the base member 15 from the guide surface 20A of the garment-side connector portion 41, so that the module-side connector portion 51 is pressed against the garment-side reference surface 45A of the garment-side connector portion 41. Consequently, the first waterproof member W1 of the garment-side connector portion 41 is pressed and compressed by the module-side reference surface 55A of the module-side connector portion 51.
When the garment-side connector portion 41 and the module-side connector portion 51 establish their fitted state, as shown in
As described above, even when the contact portions 33A of the spring-like second contacts 33 of the module-side connector portion 51 are configured not to project beyond the module-side reference surface 55A, the module-side connector portion 51 can be fitted with the garment-side connector portion 41 simply by rotating and sliding the module-side connector portion 51 relative to the garment-side connector portion 41, a small and thin wearable device is obtained, and a burden applied on a wearer's body is reduced at the time of connecting the connector, as with Embodiment 1.
In addition, when the garment-side connector portion 41 and the module-side connector portion 51 are in the fitted state, the first waterproof member W1 is compressed, so that water is prevented from entering the portions at which the contact surfaces 13C of the first contacts 43 of the garment-side connector portion 41 and the contact portions 33A of the second contacts 33 of the module-side connector portion 51 are in contact with each other.
Embodiment 3
While in Embodiment 1, the first waterproof member W1 surrounding the contact surfaces 13C of the first contacts 13 is disposed on the garment-side reference surface 15A of the garment-side connector portion 11, the invention is not limited thereto.
In Embodiment 3, the first waterproof member W1 is not provided on a garment-side reference surface 61A of a garment-side connector portion 61 as shown in
Except for not having the first waterproof member W1 on the garment-side reference surface 61A, the garment-side connector portion 61 has the same configuration as the garment-side connector portion 11 in Embodiment 1, and except for having the second waterproof member W2 on the module-side reference surface 62A, the module-side connector portion 62 has the same configuration as the module-side connector portion 31 in Embodiment 1.
Even with this configuration, when the garment-side connector portion 61 and the module-side connector portion 62 are in the fitted state, the second waterproof member W2 disposed on the module-side reference surface 62A of the module-side connector portion 62 is pressed and compressed by the garment-side reference surface 61A of the garment-side connector portion 61, so that water is prevented from entering the portions at which the contact surfaces 13C of the first contacts 13 of the garment-side connector portion 61 and the contact portions 33A of the second contacts 33 of the module-side connector portion 62 are in contact with each other, as with the slide connector of Embodiment 1.
Embodiment 4
Even in the slide connector configured such that the contact portions 33A of the spring-like second contacts 33 do not project beyond the module-side reference surface 55A of the module-side connector portion 51 as in Embodiment 2 described above, the second waterproof member W2 may be provided on a module-side connector portion in the same manner as in Embodiment 3.
Except for having the second waterproof member W2 on the module-side reference surface 63A, the module-side connector portion 63 has the same configuration as the module-side connector portion 51 in Embodiment 2.
Although not illustrated, a garment-side connector portion used in the slide connector of Embodiment 4 has the same configuration as the garment-side connector portion 41 in Embodiment 2 except for not having the first waterproof member W1.
Even with this configuration, when the garment-side connector portion and the module-side connector portion 63 are in the fitted state, the second waterproof member W2 disposed on the module-side reference surface 63A of the module-side connector portion 63 is pressed and compressed by the garment-side reference surface of the garment-side connector portion, so that water is prevented from entering the portions at which the contact surfaces 13C of the first contacts 43 of the garment-side connector portion and the contact portions 33A of the second contacts 33 of the module-side connector portion 63 are in contact with each other, as with the slide connector of Embodiment 2.
In Embodiments 1 to 4 described above, the numbers of the first contacts 13 and 43 and the number of the second contacts 33 are not limited to ones illustrated in the drawings, and it suffices if each of the numbers is plural.
While, in Embodiments 1 and 4, the first contacts 13 and 43 and the second contacts 33 are separately arranged to form a circle, they may be separately arranged to form an arc, i.e., a part of a circle.
Embodiment 5
In Embodiments 1 to 4 described above, the fitted state is established by rotating and sliding the module-side connector portion 31, 51, 62 or 63 relative to the garment-side connector portion 11, 41 or 61; however, the invention is not limited thereto.
The garment-side connector portion 71 includes a rectangular garment-side connector body 72, a plurality of plate-shaped first contacts 73 linearly arranged on the garment-side connector body 72, and a plurality of locking portions 74 formed in the garment-side connector body 72.
The garment-side connector body 72 includes a base member 75 in a rectangular plate shape and a frame member 76 in a rectangular frame shape attached to the outer edge of a garment-side reference surface 75A that is formed of a surface of the base member 75. The frame member 76 is provided with a rectangular opening 77 at its center, and the plurality of first contacts 73 are each partially exposed on the garment-side reference surface 75A of the base member 75 through the opening 77 of the frame member 76. The locking portions 74 are located closer to the outer edge of the garment-side connector portion 71 than the first contacts 73 are and arranged along the inner peripheral edge of the frame member 76.
As with the first contacts 13 in Embodiment 1, the first contacts 73 each have a contact surface, an inclined surface continuous with the contact surface, and a flat surface continuous with the inclined surface. The contact surface, the inclined surface and the flat surface are exposed on the garment-side reference surface 75A of the base member 75. The first contacts each further have an external connection portion (not shown) protruding at the outer edge of the garment-side reference surface 75A of the base member 75 and covered by the frame member 76.
A plurality of notches 79 are formed in the frame member 76 to open toward the opening 77, and locking surfaces 74A are formed in positions adjacent to the respective notches 79. The notches 79 are arranged along the inner peripheral edge of the frame member 76 so as not to have rotational symmetry.
The module-side connector portion 81 includes a module-side connector body 82 in a rectangular box shape, and the module-side connector body 82 is composed of a module case 85 and a plate-shaped lid portion 86 attached to the module case 85. A plurality of portions to be locked 84 project from lateral surfaces of the module case 85. The portions to be locked 84 are formed in positions corresponding to the notches 79 of the garment-side connector portion 71, in other words, formed along the outer peripheral edge of the module case 85 so as not to have rotational symmetry.
As shown in
The second waterproof member W2 having a closed shape surrounding the contact portions 33A of the spring-like second contacts 33 is disposed on the module-side reference surface 85A of the module-side connector portion 81. The second waterproof member W2 projects from the module-side reference surface 85A.
The module-side connector portion 81 as above is overlapped on the garment-side connector portion 71, and the portions to be locked 84 of the module-side connector portion 81 are inserted into the notches 79 of the garment-side connector portion 71 to place the module-side connector portion 81 in a first position P1, as shown in
When the module-side connector portion 81 is linearly slid relative to the garment-side connector portion 71 from the first position P1 to a second position P2 as shown in
When the module-side connector portion 81 is in the second position P2, the portions to be locked 84 of the module-side connector portion 81 are each inserted in the corresponding locking portion 74 formed between the locking surface 74A of the garment-side connector portion 71 and the garment-side reference surface 75A of the base member 75, and the fitted state between the garment-side connector portion 71 and the module-side connector portion 81 is locked.
When the garment-side connector portion 71 and the module-side connector portion 81 are in the fitted state, the second waterproof member W2 disposed on the module-side reference surface 85A of the module-side connector portion 81 is pressed and compressed by the garment-side reference surface 75A of the garment-side connector portion 71, so that water is prevented from entering the portions at which the contact surfaces of the first contacts 73 of the garment-side connector portion 71 and the contact portions 33A of the second contacts 33 of the module-side connector portion 81 are in contact with each other.
Since the notches 79 of the garment-side connector portion 71 are arranged along the inner peripheral edge of the frame member 76 so as not to have rotational symmetry and the portions to be locked 84 of the module-side connector portion 81 are arranged along the outer peripheral edge of the module case 85 so as not to have rotational symmetry, the module-side connector portion 81 is fitted with the garment-side connector portion 71 always in a defined rotational position, thus preventing fitting in a wrong position.
As described above, even with the configuration in which the module-side connector portion 81 is linearly slid relative to the garment-side connector portion 71, the module-side connector portion 81 can be fitted with the garment-side connector portion 71 simply by sliding the module-side connector portion 81 relative to the garment-side connector portion 71, a small and thin wearable device is obtained, a burden applied on a wearer's body is reduced at the time of connecting the connector, and owing to the second waterproof member W2, water is prevented from entering the portions at which the contact surfaces of the first contacts 73 of the garment-side connector portion 71 and the contact portions 33A of the second contacts 33 of the module-side connector portion 81 are in contact with each other, as with Embodiments 1 to 4.
As with the garment-side connector portion 11 in Embodiment 1, the garment-side connector portion 71 may have guide surfaces each of which lies between the locking surface 74A and the notch 79 and is inclined to the garment-side reference surface 75A. Alternatively, a locking surface inclined to the garment-side reference surface 75A may be disposed next to each notch 79. With this configuration, by linearly sliding the module-side connector portion 81 from the first position P1 to the second position P2, the module-side connector portion 81 can be pressed against the garment-side reference surface 75A of the garment-side connector portion 71 with an increasing force, thereby compressing the second waterproof member W2.
As long as the garment-side connector portion 71 and the module-side connector portion 81 have the plurality of first contacts 73 and the plurality of second contacts 33, respectively, the numbers of the first contacts 73 and the second contacts 33 are not limited.
