ELECTRICAL CONNECTIONS FOR WEARABLES AND OTHER ARTICLES
This invention is related to electrical connections in wearable garments and other articles that enable the transfer of electrical signals or electrical power from one site in the garment or article to another site on the garment or article by the use of an electrical conductor printed along the length of a sewable substrate which bridges the two sites.
1 . An electrical connection from an electrical conductor inside a wearable garment to a designated site on the outer side of the garment, the connection comprising:
an electrical conductor printed along the length of a bridging sewable substrate, wherein one end of the bridging sewable substrate is placed such that the printed conductor at that end of the bridging sewable substrate is in contact with the electrical conductor inside the garment, wherein one or more stitches with non-conductive thread are sewn through the bridging sewable substrate with each stitch encompassing the portions of the two electrical conductors that are in contact, thereby providing the compression necessary to form an electrical connection between the two conductors and wherein the other end of the bridging sewable substrate is placed at the designated site.
2 . The electrical connection of claim 1 , wherein the end of the bridging sewable substrate at the designated site has been passed through an opening in the garment that provides access to the designated site so that the bridging sewable substrate overlaps the outer side of the garment as it approaches the designated site.
3 . The electrical connection of claim 1 , wherein the end of the bridging sewable substrate at the designated site has been passed through a seam in the garment that provides access to the designated site so that the bridging sewable substrate overlaps the outer side of the garment as it approaches the designated site.
4 . The electrical connection of claim 1 , wherein the end of the bridging sewable substrate at the designated site has been folded around an edge of the garment so that the bridging sewable substrate overlaps the outer side of the garment as it approaches the designated site.
5 . The electrical connection of claim 1 , wherein the electrical conductor inside the garment is a wire.
6 . The electrical connection of claim 1 , wherein the electrical conductor inside the garment is an electrical conductor printed on a sewable substrate and the one or more stitches are sewn through both sewable substrates.
7 . The electrical connection of claim 1 , wherein the designated site is in a pocket of the garment.
8 . The electrical connection of claim 1 , wherein the designated site is in a flap or a folded flap on the garment.
9 . The electrical connection of claim 1 , wherein the wearable garment is a single layer garment.
10 . The electrical connection of claim 1 , wherein the wearable garment is a multi-layer garment.
11 . The electrical connection of claim 1 , the bridging sewable substrate comprising thermoplastic urethane.
12 . The electrical connection of claim 1 , wherein the electrical conductor printed along the length of the bridging sewable substrate is formed from a polymer thick film conductor composition.
13 . The electrical connection of claim 12 , wherein the polymer thick film conductor composition is a polymer thick film silver composition.
14 . The electrical connection of claim 1 , the electrical connection further comprising one or more additional electrical conductors printed along the length of the bridging sewable substrate.
15 . The electrical connection of claim 1 , wherein the bridging sewable substrate with the printed electrical conductor consists of two or more separate pieces of sewable substrate each with an electrical conductor printed along its length and wherein the printed conductors of neighboring pieces of substrate are placed in contact and the electrical connection of the printed electrical conductors on the two or more pieces of substrate is achieved by means of:
a) stitches with non-conductive thread, wherein each stitch is sewn through the neighboring sewable substrates and wherein each pair of contacted conductors is encompassed by at least one stitch, thereby providing the compression necessary to form an electrical connection of each pair; or
b) lamination of two neighboring pieces of substrate; or
c) fasteners compressing the two neighboring pieces of substrate together.
16 . An electrical connection from a first site on an article to a second site on the article, the connection comprising:
an electrical conductor printed along the length of a bridging sewable substrate, wherein one end of the bridging sewable substrate is placed such that the printed conductor at that end of the bridging sewable substrate is in contact with an electrical conductor at the first site, wherein one or more stitches with non-conductive thread are sewn through the bridging sewable substrate with each stitch encompassing the portions of the two electrical conductors that are in contact, thereby providing the compression necessary to form an electrical connection between the two conductors and wherein the other end of the bridging sewable substrate is placed at the second site.
