Technical Field

The invention relates to a method for electrically connecting an electronic component to a flexible flat structure, such as a textile, a fabric, a nonwoven or a knitted fabric.

Background

The publication DE 102016116028 a1, which possibly forms the latest prior art, describes a method for fastening electronic components to a flexible textile fabric. The construction elements are embroidered onto the textile sheet material by means of an embroidery machine. The component is designed as a clothing gold foil and is applied to the textile by means of embroidery in the area of the guiding clothing gold foil.

Disclosure of Invention

The invention relates to a method for electrically connecting an electronic component to a flexible flat structure having the features of claim 1. The invention further relates to an electronic device having the features of claim 14. Preferred and/or advantageous embodiments of the invention result from the dependent claims, the description and the drawings.

A method for electrically connecting an electronic component to a flexible flat structure is the subject of the present invention. The electrical connection is designed, for example, for electrically contacting the electronic component, for example, with a current supply and/or a voltage supply of the flexible printed circuit board. In addition to the electrical connection of the components, the method is also designed, for example, for mechanically and/or materially fixing the electronic components to the flexible flat structure. By means of the method, a smart textile can be obtained by placing the electronic components on and/or connecting them to the flexible textile. The electronic component can be designed and/or comprise, for example, a light source, for example an LED, a sensor and/or an actuator. In particular, the electronic component comprises an electrical and/or electronic functional element. Furthermore, the component can comprise a circuit board, also referred to as a carrier. The functional element is preferably arranged on the carrier. Furthermore, the component can comprise, for example, conductor tracks for electrically and/or electrically connecting one and/or more functional elements of the component. Examples for smart textiles are for example apparel pieces comprising sensors and/or actuators, e.g. gloves or other apparel pieces for gesture recognition, such as socks or shirts for detecting vital functions of a wearer. Industrial textiles, household textiles, textiles for surface decoration (for example in vehicle interiors) and the like can also be functionalized accordingly.

The flexible textile structure comprises and/or is designed as a textile, a fabric, a nonwoven or a knitted fabric. For example, the textile fabric is formed as a woven textile fabric. The textile sheet can be made of conventional and/or conventional fibers, in particular non-conductive fibers, such as cotton or synthetic fibers, such as nylon. Alternatively and/or additionally, the textile sheet can comprise a partial section which comprises and/or is formed by electrically conductive yarns. The textile fabric can form a continuous fabric, such as, for example, a textile and/or fabric web. Alternatively, the textile sheet can be processed to form a semi-finished product or a piece of clothing, for example, such textile sheet forms a glove, a sock, an underwear or an outer garment or other textile product.

A first conductor is laid on the planar structure. For example, the first conductor is applied to the surface of the planar structure. Alternatively, the first conductor can be arranged and/or laid at least partially in the planar structure. The first conductor is laid in a flat structure in a non-woven, non-knitted (unwerkt) and/or non-braided manner. The first conductor is for example a conventional conductor. In particular, the first conductor is designed as a wire, in particular as a metal wire and/or copper wire, as a metal tape or as a stranded wire. In particular, the first conductor has a bending stiffness, which precludes the use of the first conductor as a yarn and/or textile fiber. For example, the first conductor is fixed and/or applied to the textile structure, for example as a custom-Fibre arrangement (Tailored-Fibre-Placement), with a fixing thread and/or a fixing yarn. Alternatively and/or additionally, the first conductor can be glued, stamped and/or laminated. The first conductor is laid essentially as a straight line, unbent or slightly curved and in particular as the shortest connection between two points. For example, the first conductor is guided from a connection, for example a connection interface, of the flexible flat structure to the electronic component and/or to the position of the electronic component. If the first conductor is at least partially guided in the planar structure and/or is laid in the planar structure, an end or a section of the first conductor is led out of the planar structure at the location of the electronic component. The first conductor can be an outwardly electrically insulated conductor. In particular, the first conductor is de-insulated in the region of the electronic component. The first conductor and/or the laying of the first conductor are also referred to as primary guiding structures in particular.

The first conductor has a first conductivity. The first electrical conductivity is for example in the range of the conventional electrical conductivity of metal wires, for example copper or silver wires, of a stranded wire or metal band.

And fixing the electronic component on the planar structure. The support and/or the printed circuit board of the component are preferably mechanically and/or materially fixed to the flat structure. For example, the electronic component is glued, soldered, embroidered or riveted to the textile structure. Alternatively and/or additionally, the component can be inserted into the textile sheet. In particular, the electronic component is fixed to the free end of the first conductor. In particular, this position on the textile substrate is referred to as the position of the electronic component. The electronic components can have, for example, bores and/or holes, through which the components can be fastened to the floor structure, for example by embroidery, riveting or clamping. In particular, the support of the electronic component can be designed as a textile, wherein the textile support of the component can be embroidered directly or sewn on, for example.

The electronic component has at least one contact section, in particular two or more contact sections. It is particularly preferred that the number of contact sections is even. The contact section preferably comprises a contact pad and/or is designed as a metallization structure. By means of the contact section, for example, a pressure contact, in particular an electrical contact, can be made. The contact section is used in particular for electrically contacting a component with a current and/or voltage supply device, in particular a first conductor. The electronic component can have, for example, conductor tracks from the contact sections to the functional elements of the electronic component. The conductor tracks are conventional, for example printed or etched circuit boards. The contact section is preferably arranged in an edge region of the electronic component, in particular of the circuit board.

The at least one contact section is connected to the first conductor by means of an electrically conductive yarn. The electrically conductive yarn is, for example, a pure metal wire, a yarn with a metal component, for example a metal rib, a yarn coated with an electrically conductive material or a blended yarn. The electrically conductive yarn is especially knittable, knittable and/or embroiderable. The electrically conductive yarn is particularly flexible and bendable. The contacting of the first conductor is effected by means of electrically conductive yarns, which usually form an electrical connection between the contact section and the uninsulated region of the first conductor or the first conductor, for example. Alternatively and/or additionally, the first conductor can be pressed and/or pressed onto the contact section by embroidering the electrically conductive yarn, so that the contact section is in direct contact with the first conductor.

The conductive yarn has a second conductivity. The second electrical conductivity is preferably less than the first electrical conductivity. In particular, the second electrical conductivity is several orders of magnitude smaller than the first electrical conductivity. For example, the electrically conductive yarn has a smaller diameter than the first conductor. Furthermore, for example, the electrically conductive yarn and the first conductor are formed from different electrically conductive materials.

The invention is based on the following considerations, namely: the supply of electrical power to the electronic components in the smart textiles by means of the methods used hitherto does not allow higher currents to be supplied. The conductive yarns used to contact the electronic components in the smart textile typically have an electrical conductivity that is several orders of magnitude lower than that of conventional metal filaments. If higher currents are supplied to the electronic components, high power losses due to the low conductivity of the conductive yarns used must be tolerated up to now. On the other hand, conventional conductors, such as the first conductor, cannot be embroidered and thus cannot directly contact the circuit board and/or components in the textile. The present invention takes advantage of the considerations that: in order to reduce power losses, the first conductor overcomes a large distance and makes contact with the electrically conductive yarn at the component location with the result that only small power losses occur here.

In one embodiment of the invention, the connection of the first conductor to the contact section is achieved by embroidery and/or sewing with electrically conductive threads. For embroidering and/or sewing, in particular conventional and/or industrial embroidery or sewing machines can be used. By embroidery and/or sewing, for example, the electrically conductive thread as an upper thread can press the first conductor onto the contact section, press it and connect the contact section to the first conductor. For example, the electronic component, in particular the support, has a bore and/or a hole through which the electrically conductive thread is guided and/or pulled, for example by and/or by means of a needle of an embroidery or sewing machine. This design is based on the following considerations, namely: the contact between the first conductor and the contact section is achieved without soldering and in particular in an industrially and/or technically simple manner.

In particular, the first electrical conductivity is much greater than the second electrical conductivity, for example at least ten times the second electrical conductivity and preferably at least one hundred or one thousand times the latter.

Provision is optionally made for the first conductor to be arranged on the textile substrate. For example, the first conductor is arranged completely on the planar structure. Alternatively, the first conductor can be arranged outside and/or on the textile sheet, for example, in a percentage of at least 70%, preferably 80% and in particular 90%. The first conductor is preferably sewn, embroidered and/or secured in a loss-proof manner to the textile structure by means of a loop. The first conductor is preferably arranged on the textile structure by means of a fixing thread and/or a fixing yarn, wherein the fixing thread and/or the fixing yarn is in particular an electrical insulator. This design is based on the following considerations, namely: the first conductor can be guided intuitively and/or visually by means of an arrangement, application and/or placement on the surface of the textile sheet and a high degree of freedom in design is created. In particular, such a sewing can be realized easily and cost-effectively in terms of production.

In particular, the first conductor has a free end. The free end is arranged and/or generated at the location and/or in the region of the electronic component. For example, the first conductor is cut and/or deinsulated for this purpose. Such as by arranging the free end in one or more regions of the contact section. The contact and/or connection between the first conductor and the contact section is/are carried out in particular by means of and/or on the free end of the first conductor.

In particular, it is preferred that the first conductor is fixed in the component in a force-fitting, form-fitting and/or clamping-fitting manner, for example by means of a press-fit. In particular, the first conductor is fixed in and/or at the contact section in a force-fitting, form-fitting, clamping-fitting and/or pressure-fitting manner. The force-fitting, form-fitting and/or clamping fit comprises in particular the free end of the first conductor and/or is formed in particular by the free end of the first conductor.

In particular, the non-positive, positive and/or clamping-locking fastening and/or connection comprises at least one section and/or the entire contact section. The clamping, form-locking, force-fitting and/or pressure-fitting closure is formed, for example, between the contact section, the first conductor and/or the electrically conductive thread. For example, the first conductor, in particular the free end, is pressed, clamped and/or placed in the contact section in a form-fitting and/or force-fitting manner.

For example, the force-fit, form-fit, clamping-fit and/or pressure-fit connection is supported, established and/or formed by the electrically conductive threads. For example, the electrically conductive threads are embroidered, sewn and/or wound in such a way that they press and/or press the first conductor against the component, for example the contact section, as an alternative and/or in addition form-locking and/or force-locking the first conductor in the component and/or in particular in the contact section.

In one embodiment of the invention, the component, in particular the carrier, has at least two, in particular exactly two, contact sections. For example, the contact section comprises and/or is configured as a bore and/or hole, in particular as a bore and/or hole with a metallization structure and/or a contact pad. The conductor, in particular the end of the conductor which has been deinsulated and/or the free end, is placed between two contact sections. By embroidery and/or sewing, the two electrical contact sections can be and/or are connected by an electrically conductive yarn, for example as a loop or stitch. The electrical conductor is placed on the support and between the two contact sections. In such an arrangement, the electrical conductor, in particular the free end, is held in a restraining, surrounding and/or force-fitting manner by the support and the electrically conductive thread. By embroidering the two contact sections by means of electrically conductive yarns, a pressing and/or pulling force of the electrical conductor acting on the support can be obtained. In particular, the two contact sections can also be fastened to the textile sheet by means of electrically conductive threads and by embroidery.

It is particularly preferred that the electronic component, in particular the carrier, has at least one recess. For example, the recess is a recess in the support of the component. For example, the recess is formed as a recess, in particular as a complete perforation, in a plan view of the carrier. Preferably, the recess has a rectangular contour in a plan view from above, which contour is in particular designed to receive a conductor. In this embodiment, the first conductor, in particular the free end, is inserted into the recess and/or fixed therein. In particular, the recess is arranged between the two contact portions. By embroidering and/or connecting the two contact sections by means of electrically conductive threads, for example, the electrical conductors are pressed into the recesses and/or onto the textile sheet.

In one embodiment of the invention, the air gap is formed in the form of a tunnel. For example, the recess is configured as a blind hole. Preferably, the drilling direction and/or the advancing direction of the tunnel-shaped recess lies in the plane of the support. The tunnel-shaped recess is preferably closed in the circumferential direction, and can alternatively be interrupted in the circumferential direction and/or have recesses, for example one or more slits. The electrical conductor, in particular the free end, is inserted into the tunnel-shaped recess. Preferably, the inner wall and/or a section of the inner wall of the tunnel-shaped recess is electrically conductive, for example metallized. This section forms, for example, a tunnel contact section. The tunnel contact section is connected to a functional element of the electronic component, in particular electrically, for example by means of a printed conductor. By inserting the electrical conductor, in particular pressing it, and/or maintaining it in contact with the tunnel contact section, the supply of current and/or voltage to the component is permitted and/or achieved.

Optionally, it is provided that the electronic components, the contact sections, the tunnel contact sections and/or the conductor ends are embedded in a protective material and/or a protective base layer. For example, the protective substance and/or the protective substrate is embodied as a resin, adhesive or insulating substance. The protective material is applied to the respective section, for example by means of a dispenser. It is particularly preferred to introduce an adhesive compound, for example, a conductive plastic, onto the contact sections and/or into the recesses, so that there a mechanical connection of the conductive threads to the contact sections and/or of the electrical conductors to the recesses, in particular to the tunnel contact sections, is produced. Thus, mechanical stability and electrical contact are unified. For example, embedding and/or gluing, for protection against mechanical, chemical and/or environmental influences or weather influences, such as dust and moisture.

It is particularly preferred to bond the electronic component, in particular the carrier, to the textile structure. Depending on the desired application, the electronic component can be bonded to the flat structure with any adhesive, in particular an electrically insulating or conductive adhesive.

In particular, the method can provide that the conductor is passed past the electronic component, in particular the carrier, and/or is not placed or inserted directly. For example, in such a configuration, the electronic component can be arranged next to the further guided electrical conductor and/or between two parallel guided electrical conductors. In particular, no free end is required here. In such a configuration, for example, a series circuit of electronic components can be carried out along one or more first conductors. In this case, the electrically conductive threads, in particular also the embroidery, bring the electronic component into contact with the first conductor which is external to the electronic component and/or parallel to the electronic component. Here, for example, one or more loops or loops are embroidered, wherein the electrical conductor and/or the contact section is surrounded by the loop or loops. In particular, it is provided that, for an electrical conductor which is not inserted into the recess, in particular if the electrical conductor is outside the support, the free end is formed and bent into a wave or spiral shape in order to reduce the tension and wear of the electrical conductor, so that the free end does not slip out of the tongues and/or loops of the fastening wire and thus causes an interruption of the current supply.

An electronic device forms another subject of the invention. The electronic device is in particular obtainable and/or the result of a method according to any of the preceding claims or as described hereinbefore. The electronic device comprises a flexible textile, knitted, non-woven or knitted fabric. Furthermore, the electronic device comprises at least one electronic component or a plurality of electronic components. The electronic components are arranged and/or fixed on a flexible flat structure. The first electrical conductor, in particular a conventional electrical wire, strand or metal strip, is in electrical contact with the electronic component. The electrical contact and/or the electrical contact between the first conductor and the electronic component is made by electrically conductive yarns. The electrically conductive yarn preferably has a lower electrical conductivity than the first conductor.

It is particularly preferred that the electronic device and/or the textile form factor is designed as a textile, in particular as a smart textile. It is particularly preferred that the electronic device and/or the planar configuration form an item of apparel, such as a glove, sock, garment or underwear.

Drawings

Further advantages, functions and embodiments of the invention result from the figures and their description. Here:

FIG. 2 illustrates a side view of the electronic device of FIG. 1;

FIG. 3 illustrates a side view of another embodiment of an electronic device;

fig. 4 shows a cut-out of a top view of an electronic device as another embodiment.

Detailed Description

Fig. 1 shows a cut-out of a top view of an electronic device obtained from the method as described above as a first embodiment. The electronic device comprises a flexible planar structure 1. The flexible textile sheet 1 is, for example, a textile fabric which can be cut out and sewn to form, for example, a glove or a fabric strip. The textile fabric 1 is preferably a knitted and/or woven fabric made of electrically non-conductive fibers and/or yarns, for example made of cotton or plastic fibers. Alternatively or additionally, the flexible textile sheet 1 can comprise electrically conductive yarns, for example for electrical shielding or for supplying power.

Two first conductors 2 are arranged on the flexible planar structure 1. The first conductor 2 is designed as a metal wire, for example a copper wire. The conductor 2 can be electrically insulated or de-insulated outwards. The first conductor 2 is guided on a flexible sheet-like structure 1. This can be done, for example, on the lateral or medial side of the textile sheet 1, in particular if a piece of clothing, for example a glove, is made of it and/or is to be made of it. The guidance of the conductor 2 is preferably carried out linearly. The electrical conductor 2 is formed in particular in a flexurally rigid manner. The electrical conductor 2 has an electrical conductivity, wherein the electrical conductivity has an electrical conductivity of a metal wire, such as copper, silver or gold.

The first conductor 2 is fixed to the planar structure 1 by means of a fixing wire 3. The fixing wire is preferably a natural wire or a plastic wire, in particular an electrically insulating wire. By means of the fixing thread, the conductor 2 is stitched and/or embroidered onto the planar formation 1. In particular, the fastening threads guided by the conductors 2 form loops and/or loops, which fasten and/or hold the conductors 2 on the flat former 1. The conductor 2 is used to supply an electrical component 4 with current and/or voltage. In this case, a current supply and/or a voltage supply from a current source and/or a voltage source to component 4 takes place.

The first conductor 2 has a free end 5. The free end 5 is in particular an electrically conductive end, for example, de-insulated. Said free end 5 is arranged at the location of the electrical component 4.

The electrical component 4 has a support 6 and a functional element 7. The carrier 6 is designed, for example, as a printed circuit board. The support 6 can also be designed in particular as a textile and/or film-shaped support. On the carrier 6, a printed conductor 8 is arranged. The conductor tracks serve for contacting and/or supplying the functional elements 7. The conductor tracks connect the contact sections 9 to the functional elements 7. The contact section 9 is designed, for example, as a contact pad. The contact section 9 has a bore, wherein the bore is at least partially metallized and/or electrically conductive. The electrically conductive yarn 10 can be threaded through the contact section 9.

Between the contact sections 9, in each case a recess 11 is arranged. The recess 11 is configured, for example, as a recess and/or a perforation passing through the support 6.

In each case, the free end 5 of the electrical conductor 2 is placed into the recess 11. By means of the recess, the conductor 2 is at least partially protected against slipping out and/or sliding out at least in the plane of the abutment 6. In order to prevent the free end 5 of the conductor 2 from slipping out of the recess 11, the electrically conductive yarn is guided through the contact section 9 and onto the free end of the conductor 2. The electrically conductive yarns are guided downward through the textile 1 in such a way that the electrically conductive yarns 10 hold the conductors, in particular the free ends 5, in the recesses in a loss-proof manner and in particular press against the textile 1 and/or press against the textile 1.

The electrical contact of the electrical conductor 3 with the electrical component 4 and in particular with the functional element 7 is made via the electrically conductive yarn 10. In this case, a connection is made between the contact section 9 and the free end 5. Such a connection, in particular a very short connection length, is formed by the electrically conductive yarn 10. The electrically conductive yarn 10 has a lower electrical conductivity than the first conductor 2. However, the power loss resulting from the use of the electrically conductive yarn 10 is negligible over this small distance and can be minimized in this way by forming a plurality of loops of the yarn 10 through the contact section 9 and via the free end 5. By using a conductor 2 with better conductivity, the power loss due to the electrical conduction on the textile sheet 1, which must be overcome for a longer distance, can be reduced.

Fig. 2 shows a side view, in particular a sectional view, of the electronic device of fig. 1. It can be seen here that the electrical conductor 2, in particular the free end, is held in the recess 11 in a loss-proof, form-fitting and, in particular, force-fitting manner. The conductor 2 is inserted into the recess 11 and is laterally limited by the abutment 6. The position of the conductor 2 is limited downwards by the flexible sheet-like structure 1. The limitation of the position of the recess 11 and/or of the conductor 2 is effected upwards by the flexible and electrically conductive thread 10. The thread 10 is guided downward through the flat structure 1, so that the conductor 2 is pressed onto the flat structure 1 by the thread. The electrical conductor 2 and the electrical component 4, in particular the functional element 7, are contacted by the electrically conductive yarn 10. The yarns 10 form an electrical connection between the conductor 2 and the contact section 9, which is designed here as a bore hole with a metallization structure.

Fig. 3 shows another embodiment of the electronic device in the same cross-section as fig. 2. In contrast to fig. 2, the recess 11 is formed in a tunnel-like manner, for example as a blind hole. In this exemplary embodiment, however, the blind hole is not restricted to the bottom side, in this case to the floor structure 1, and is open. Alternatively, the limitation can also be made to the planar structure 1. Furthermore, the recess 11 is limited upwards by the abutment section 12. The conductor 2 is inserted or placed in the recess 11, the electrically conductive yarn 10 being guided onto the support section 12. In this case, the thread is guided from below through the textile 1, through the contact section 9, via the support section 12, through the contact section 9 and down through the textile 1. The conductor 2 is thus fixed in the recess 11 by fixing the carrier section 12. In particular, the inner side of the support section 12, in particular of the recess 11, is thereby pressed and/or pressed against the conductor 2. For example, the upper side of the recess 11 (also referred to as the tunnel upper side) is designed to be electrically conductive and is pressed against the conductor 2 by electrically conductive threads, so that the conductor is contacted via this section, in particular as a supplement to the contacting via the contact section 9.

Fig. 4 shows another embodiment of an electronic device. In this arrangement, the electronic component, in particular the carrier, is identical or similar to the electronic component, in particular the carrier, in fig. 1, 2 and 3. The first conductor 2 does not end here at the location of the electronic component 4. The conductor 2 is guided further here, in particular at the electronic component 4. For the electrical contact of the component 4 and the conductor 2, an electrically conductive yarn 10 is used. The connection of the electrical conductor 2 to the contact section 9 is formed here by embroidery, sewing or loop formation. For example, loops or loops are formed by means of electric yarns 10 guided onto the electric conductors 2. This loop or stitch can be continued or, if interrupted by a downward stitch, guided into the contact portion 9. By means of this embroidery and/or stitching, not only is the conductor 2 fixed again to the textile sheet 1 by the electrically conductive threads 10, but the support 6 and the electronic component 4 are thus also fixed to the textile sheet 1.
