The present invention relates to a garment connector, particularly to a connector to be attached to a garment.
As a connector to be attached to a garment, for example, a connector 1 as illustrated in
As illustrated in
By pressing the frame member 5 against the base member 4 in a state where a cloth 8 of garment is sandwiched between the base member 4 and the frame member 5, the plurality of external connection portions 6A of the base member 4 and the plurality of protrusions 7 are fitted into the plurality of fitting holes of the frame member 5 respectively, with the cloth 8 being sandwiched, to thereby allow the garment-side connector portion 2 to be attached to the cloth 8. Opening portions 9 are prepared in the cloth 8 beforehand and a plurality of wiring portions 10 are arranged on the back face of the cloth 8. The plurality of wiring portions 10 of the cloth 8 are respectively pressed into the fitting holes of the frame member 5 while being in contact with the corresponding external connection portions 6A of the base member 4, and are thereby connected to the external connection portions 6A.
The plurality of contact portions 6 of the base member 4 are exposed through opening portions 9 of the cloth 8. When the module-side connector portion 3 is fitted with the garment-side connector portion 2, a plurality of contact portions (not illustrated) of the module-side connector portion 3 come into contact with the plurality of contact portions 6 of the base member 4 and are electrically connected to the plurality of wiring portions 10 of the cloth 8 via the plurality of external connection portions 6A.
In this way, while sandwiching the cloth 8 of the garment between the base member 4 and the frame member 5, the connector 1 of JP 2017-182897 A makes the plurality of external connection portions 6A and the plurality of protrusions 7 of the base member 4 be fitted into the plurality of fitting holes of the frame member 5 respectively, to thereby allow the garment-side connector portion 2 to be attached to the cloth 8. Accordingly, in order to firmly attach the garment-side connector portion 2 to the garment, the sizes of the external connection portions 6A and the protrusions 7 of the base member 4 and the plurality of fitting holes of the frame member 5 need to be varied depending on the thickness of the cloth 8.
The present invention has been made in order to solve the above-described drawbacks in the related arts, and aims at providing a garment connector that can be readily attached to a garment irrespective of the thickness of the garment.
A garment connector according to the present invention includes a connector body, one or more contacts held by the connector body, one or more conductive members held by the connector body and corresponding to the one or more contacts, and a connector fixation member in a sheet-like shape held by the connector body and extending to an exterior of the connector body, wherein the garment connector is attached to a garment by fixing the connector fixation member to the garment at the exterior of the connector body.
Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings.
The connector body 12 includes a first insulator 15 and a second insulator 16 to be coupled to the first insulator 15. The connector fixation member 14 is sandwiched to be held between the first insulator 15 and the second insulator 16 and extends to an exterior of the connector body 12 to seamlessly surround the outer peripheral portion of the connector body 12.
The first insulator 15 and the second insulator 16 both have a substantially rectangular flat plate shape. As illustrated in
As illustrated in
For ease of understanding, the short-side direction of the first insulator 15 and the second insulator 16 that are formed in substantially rectangular shapes is defined as the X direction, the long-side direction is defined as the Y direction, and the direction in which each contact 13 protrudes perpendicularly to the XY plane is defined as the +Z direction.
That is, six contacts 13 are arranged in two rows, with three in each row, substantially along the Y direction. Three conductive members 18 corresponding to three contacts 13 arranged on the +X direction side among the six contacts 13 are arranged to extend in the +X direction from the connector body 12, and three conductive members 18 corresponding to the three contacts 13 arranged on the −X direction side are arranged to extend in the −X direction from the connector body 12.
As illustrated in
The first insulator 15 includes a plurality of contact attachment holes 15A through which the plurality of contacts 13 pass.
The connector fixation member 14 in a sheet-like shape has insulating properties and is made of resin or cloth. Moreover, the connector fixation member 14 includes an opening portion 14A located at the center and a plurality of through holes 14B formed along the peripheral edge of the opening portion 14A.
The first waterproof sheet 19 and the second waterproof sheet 20 are made of a solid adhesive in a sheet or film form having a rectangular shape approximately equivalent in size to the first insulator 15 and the second insulator 16. For example, a hot melt-type thermoplastic adhesive can be used as the first waterproof sheet 19 and the second waterproof sheet 20. The thermoplastic adhesive, which is also referred to as so-called hot melt adhesive, is a solid at room temperature, and form a bond by heating to melt and cooling to solidify.
The first waterproof sheet 19 and the second waterproof sheet 20 include a plurality of through holes 19A and 20A corresponding to the plurality of contacts 13, respectively, and a plurality of through holes 19B and 20B formed along the peripheral edges thereof, respectively. In addition, the first waterproof sheet 19 and the second waterproof sheet 20 includes a plurality of small through holes 19C and 20C arranged around the respective through holes 19A and 20A.
The plurality of conductive members 18 are each members fabricated into a cloth form using conductive fibers and have both conductivity and flexibility.
The permeable adhesive sheets S, like the first waterproof sheet 19 and the second waterproof sheet 20, are made of a solid adhesive. For example, a hot melt-type thermoplastic adhesive can be used as the permeable adhesive sheet S. However, the permeable adhesive sheets S are preferably an adhesive that has higher fluidity when being heated to melt than the adhesive of the first waterproof sheet 19 and the second waterproof sheet 20, and easily permeates into the interior of the plurality of conductive members 18.
The second insulator 16 includes a plurality of contact protrusions 16A corresponding to the plurality of contacts 13 and each protruding in the +Z direction and includes a plurality of through holes 16B formed along the peripheral edge. Further, the second insulator 16 includes a plurality of small concave portions 16C arranged around each contact protrusion 16A.
As illustrated in
The plurality of contact attachment holes 15A of the first insulator 15 and the plurality of through holes 19A of the first waterproof sheet 19 each have an inner diameter that is slightly larger than the outer diameter of the projecting portion 13A of the contact 13 and smaller than the outer diameter of the flange 13B.
A method of assembling the garment connector 11 is herein described.
First, as illustrated in
Further, on the face of the first insulator 15 on the −Z direction side, a plurality of small protrusions 15C are formed to protrude around each of the contact attachment holes 15A. The plurality of through holes 19C and 20C of the first waterproof sheet 19 and the second waterproof sheet 20 and the plurality of concave portions 16C of the second insulator 16 are each formed at a position corresponding to each of the plurality of protrusions 15C of the first insulator 15.
Next, as illustrated in
As such, the plurality of contact attachment holes 15A and the plurality of protrusions 15C of the first insulator 15 are located within the opening portion 14A of the connector fixation member 14 and exposed through the opening portion 14A.
Further, as illustrated in
As such, the plurality of through holes 19A of the first waterproof sheet 19 are each located directly above the corresponding contact attachment hole 15A of the first insulator 15.
Then, as illustrated in
Next, as illustrated in
Note that among the six contacts 13, three conductive members 18 corresponding to the three contacts 13 arranged on the +X direction side are arranged to extend in the +X direction from above the first waterproof sheet 19, while three conductive members 18 corresponding to the three contacts 13 arranged on the −X direction side are arranged to extend in the −X direction from above the first waterproof sheet 19.
As such, the leading ends of the internal conductive portions 18A of the respective conductive members 18 are each located directly above the flange 13B of the corresponding contact 13. However, since the leading ends of the internal conductive portions 18A of the conductive members 18 are brought into contact with the plurality of small protrusions 15C formed to protrude around the contact attachment holes 15A of the first insulator 15, the arrangement positions are restricted. As a result, the plurality of conductive members 18 are prevented from coming into contact with each other to be electrically short-circuited.
Further, as illustrated in
As illustrated in
Note that a plurality of through holes 20A of the second waterproof sheet 20 are to be located directly above one ends of the plurality of conductive members 18 arranged above the flanges 13B of the plurality of contacts 13.
Next, as illustrated in
At this time, as illustrated in
In this way, in a state where the connector fixation member 14, the first waterproof sheet 19, the plurality of contacts 13, the plurality of conductive members 18, the two permeable adhesive sheets S, and the second waterproof sheet 20 are sandwiched between the first insulator 15 and the second insulator 16, the first waterproof sheet 19 and the second waterproof sheet 20 are subjected to a heat treatment to melt, and are then cooled to solidify. This allows the first insulator 15 and the second insulator 16 to adhere to each other and a waterproof layer composed of a solidified adhesive to be formed between the first insulator 15 and the second insulator 16, so that water is prevented from entering between the first insulator 15 and the second insulator 16.
The two permeable adhesive sheets S disposed on the plurality of conductive members 18 also melt by the heat treatment, where the permeable adhesive sheet S has high fluidity at the time of melting, thus the molten adhesive permeates into the conductive member 18 made of conductive fibers, and is then cooled to solidify. Accordingly, the adhesive forming the permeable adhesive sheet S enters and solidifies inside the conductive member 18, and this also prevents water from entering between the first insulator 15 and the second insulator 16 from the outside through the inside of the conductive member 18.
Subsequently, the leading end portions of the plurality of fixation protrusions 15B of the first insulator 15 protruding in the −Z direction from the plurality of through holes 16B of the second insulator 16 are heated to melt, thereby being fused to the surface on the −Z direction side of the second insulator 16. This allows the first insulator 15 and the second insulator 16 to be coupled to each other to form the connector body 12, whereby the assembling of the garment connector 11 illustrated in
Next, a method of attaching the garment connector 11 of Embodiment 1 to a garment will be described.
First, as illustrated in
When the garment connector 11 is located at the connector attachment position 22 of the cloth 21, the external conductive portions 18B of the plurality of conductive members 18 of the garment connector 11 are each located directly above the leading end portion of the corresponding garment-side conductor portion 23 disposed on the back face of the cloth 21 as illustrated in
Then, the external conductive portions 18B and the leading end portions of the garment-side conductor portion 23 corresponding to each other are sewn up together with the cloth 21 using a conductive yarn 24. This allows the plurality of conductive members 18 of the garment connector 11 to be each electrically connected to each of the plurality of garment-side conductor portions 23 of the cloth 21.
Note that, in
Subsequently, as illustrated in
As illustrated in
In this way, the garment connector 11 can be attached to the garment by sewing the connector fixation member 14 to the cloth 21 at the exterior of the connector body 12 without sandwiching the cloth 21 of garment. This allows the garment connector 11 to be easily and firmly attached to the garment irrespective of the thickness of the garment. That is, the garment connector 11 includes none of parts of which sizes or the like need to be varied depending on the thickness of the cloth 21 of garment.
Further, the first waterproof sheet 19, the second waterproof sheet 20, and the permeable adhesive sheets S melt and then solidify, whereby waterproof is provided between the first insulator 15 and the second insulator 16, and thus, even if a garment to which the garment connector 11 is attached is, for example, exposed to rain or laundered, water is prevented from entering between the first insulator 15 and the second insulator 16.
The electronic equipment module 31 includes a housing 32 made of an insulating material as illustrated in
As illustrated in
A plurality of contact receiving holes 33B corresponding to the plurality of contacts 13 of the garment connector 11 are formed on the face facing the −Z direction of the convex portion 33A of the first housing member 33. Further, a groove 33C for mounting the fitting ring 35 is formed on the external side face of the convex portion 33A to surround the convex portion 33A.
The contact 36 mounted on the board 37 is a receptacle-type contact that is connected to the plug-type contact 13 of the garment connector 11 when the electronic equipment module 31 is fitted into the garment connector 11, and is made of a conductive material such as metal.
In the waterproof member 38, a plurality of opening portions 38A into each of which the plurality of contacts 36 are each inserted are formed.
The board 37 on which the plurality of contacts 36 are mounted is fixed to the first housing member 33 by the fixing screws 39 with the waterproof member 38 interposed in between and the second housing member 34 is coupled to the first housing member 33, and the fitting ring 35 is mounted in the groove 33C of the convex portion 33A of the first housing member 33, whereby the electronic equipment module 31 illustrated in
As illustrated in
Also, the convex portion 33A of the electronic equipment module 31 is inserted into the mating connector receiving portion 17 of the garment connector 11, so that the plurality of plug-type contacts 13 of the garment connector 11 are inserted into the plurality of receptacle-type contacts 36 through the plurality of the contact receiving holes 33B of the electronic equipment module 31 to be electrically connected to the plurality of receptacle-type contacts 36.
In this manner, the electronic equipment module 31 can be used as a wearable device connected to the garment-side connector portion.
In the garment connector 11 of Embodiment 1 described above, all of the external conductive portions 18B of the plurality of conductive members 18 disposed outside the connector body 12 are covered by the connector fixation member 14 as illustrated in
Further, the cloth 21 of garment used in Embodiment 1 includes the plurality of garment-side conductor portions 23 arranged on the back face as illustrated in
When the garment connector 41 is located at a connector attachment position 52 on the front face of the cloth 51 of garment, the leading ends of the external conductive portions 48B of the plurality of conductive members 48 of the garment connector 41 are located on the plurality of garment-side conductor portions 53 arranged on the front face of the cloth 51 and come into contact with the plurality of garment-side conductor portions 53, as illustrated in
Note that, while the sewing can be performed using the conductive yarn 24 instead of the insulating yarn 25, the conductive yarn 24 is unnecessary to be used because the external conductive portions 48B and the garment-side conductor portions 53 are in contact with each other, and even the use of the insulating yarn 25 enables the conductive member 48 of the garment connector 41 to be electrically connected to the garment-side conductor portions 53 of the cloth 51. Also, the conductive member 48 of the garment connector 41 and the garment-side conductor portion 53 of the cloth 51 may be connected to each other, in addition to by sewing, for example, by adhering the conductive member 48 to the garment-side conductor portion 53 using a conductive adhesive, which enables these components to be electrically connected to each other.
In the garment connector 41 according to Embodiment 2, the leading end of the external conductive portion 48B of the conductive member 48 is exposed to the exterior of the connector fixation member 14, and thus, the external conductive portion 48B of the conductive member 48 can be sewn up without holding up the connector fixation member 14. However, provided that all the external conductive portions 18B of the plurality of conductive members 18 are covered by the connector fixation member 14 as in the garment connector 11 of Embodiment 1, although sewing needs to be performed while holding up the connector fixation member 14, covering the sewing portion with the connector fixation member 14 prevents the sewing portion from being exposed to rain, dust, and the like.
In addition, the garment connector 41, in which the leading ends of the external conductive portions 48B of the plurality of conductive members 48 extend to the exterior of the connector fixation member 14, can be attached onto the front face of the cloth 21 on the back face of which the plurality of garment-side conductor portions 23 are arranged as illustrated in
Further, the garment connector 11 of Embodiment 1, in which all of the external conductive portions 18B of the plurality of conductive members 18 are covered by the connector fixation member 14, may also be attached onto the front face of the cloth 51 on which the plurality of garment-side conductor portions 53 are arranged as illustrated in
When the garment connector 41 is located at the connector attachment position 52 on the front face of the cloth 51 of garment, the external conductive portions 18B of the plurality of conductive members 18 of the garment connector 11 are located on the plurality of the garment-side conductor portions 53 arranged on the front face of the cloth 51 to come into contact with the plurality of garment-side conductor portions 53. Then, the external conductive portions 18B and the garment-side conductor portions 53 corresponding to each other may be sewn up together with the cloth 51 using the insulating yarn 25 while holding up the connector fixation member 14. This allows the conductive member 18 of the garment connector 11 to be electrically connected to the garment-side conductor portion 53 of the cloth 51.
In Embodiments 1 and 2 described above, the plurality of conductive members 18 and 48 are provided in the garment connectors 11 and 41, and the plurality of conductive members 18 and 48 are connected to the plurality of garment-side conductor portions 23 and 53 of the cloths 21 and 51 of garment; however, this does not limit the invention. For example, as illustrated in
The cloth 61 includes an opening portion 62 at the connector attachment position, and the plurality of conductive members 68 are arranged such that each leading end is located in the opening portion 62. The conductive member 68 is made of conductive fibers as in the conductive member 18 in Embodiment 1.
For example, as illustrated in
Further, as illustrated in
Note that although the conductive members 18, 48, and 68 used in Embodiments 1 to 3 are all made of conductive fibers, a resin or cloth coated with a conductive film on the surface thereof may also be used, for example.
As illustrated in
In Embodiments 1 and 2, the plurality of conductive members 18 and 48 are arranged on the −Z direction side of the connector fixation member 14; however, the invention is not limited thereto, and the plurality of conductive members 18 and 48 may be arranged on the +Z direction side of the connector fixation member 14. However, in a case where the conductive members 18 and 48 do not extend to the exterior of the connector fixation member 14, the external conductive portions 18B and 48B of the conductive members 18 and 48 and the garment-side conductor portions 23 and 53 need to be sewn up together with the connector fixation member 14 using the conductive yarn 24 to electrically connect the conductive members 18 and 48 to the garment-side conductor portions 23 and 53.
The conductive members 68 used in Embodiment 3 may also be configured to be arranged on the +Z direction side of the connector fixation member 14.
Note that, while the plurality of conductive members 18 and 48 in Embodiments 1 and 2 are members independent from the connector fixation member 14, the plurality of conductive members 18 and 48 may be attached beforehand to the connector fixation member 14.
In Embodiments 1 to 3, the six contacts 13 and the six conductive members 18, 48, and 68 are used; however, the invention is not limited thereto, and it may have one or more contacts 13 and one or more conductive members 18, 48, and 68.
In Embodiments 1 and 2, the garment connectors 11 and 41 include a plurality of plug-type contacts 13, and the electronic equipment module 31 includes a plurality of receptacle-type contacts 36. Contrarily, the garment connectors 11 and 41 may include a plurality of receptacle-type contacts 36 and the electronic equipment module 31 may include a plurality of plug-type contacts 13.
