Disclosure of the invention

The invention relates to a method for electrically connecting an electronic component to a flexible sheet having the features of claim 1. Furthermore, the invention relates to an electronic arrangement with the features of claim 13. Preferred and/or advantageous embodiments of the invention emerge from the subclaims, the description and the accompanying figures.

The invention relates to a method for electrically connecting an electronic component to a flexible sheet-like structure. The electrical connection is designed, for example, to electrically contact the electronic component, for example with a current and/or voltage supply of the flexible sheet-like structure. In addition to the electrical connection of the component, the method is also designed, for example, to mechanically and/or materially fasten the electronic component to the flexible sheet-like structure. By means of the method, a smart textile can be obtained by attaching and/or connecting the electronic component to and/or on the flexible sheet-like structure. The electronic component can, for example, be designed as and/or comprise a light source, for example 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 called a carrier. The functional element is preferably arranged on the carrier. Furthermore, the component can comprise, for example, conductor tracks for electronically and/or electrically connecting the functional element and/or the functional elements of a component. Examples of smart textiles include items of clothing that include sensors and/or actuators, such as gloves for gesture recognition or other items of clothing such as socks or shirts for detecting the wearer's vital functions. Technical textiles, home textiles, textiles for surface finishing (e.g. in vehicle interiors), etc. can also be functionalized accordingly.

The flexible fabric comprises and/or is designed in particular as a textile, a woven fabric, a fleece or a knitted fabric. For example, the fabric is designed as a knitted textile. The fabric can be made of conventional and/or classic fibers, in particular non-electrically conductive fibers, such as cotton or synthetic fibers such as nylon. Alternatively and/or additionally, the fabric can comprise sections that comprise an electrically conductive yarn and/or are formed from it. The flat structure can form a continuous structure such as a textile and/or fabric strip. Alternatively, the flat structure can be processed into a semi-finished product or piece of clothing, for example such a flat structure forms a glove, a sock, underwear or outerwear or other textile products.

A first conductor is laid on the fabric. For example, the first conductor is laid on the surface of the fabric. Alternatively, the first conductor can be arranged and/or laid in the fabric at least in sections. The first conductor is laid in the fabric in an unknitted, unwoven and/or unmeshed manner. The first conductor is, for example, a conventional conductor. In particular, the first conductor is designed as a wire, in particular metal and/or copper wire, as a metal strip or strand. In particular, the first conductor has a flexural rigidity that precludes the use of the first conductor as yarn and/or textile fiber. For example, the first conductor is fixed and/or laid on the fabric with a fixing thread and/or fixing yarn, for example as tailored fiber placement. Alternatively and/or additionally, the first conductor can be glued, printed and/or laminated. The first conductor is laid essentially as a straight line, uncurved or slightly curved and in particular as the shortest connection between two points. For example, the first conductor is led from a connection, for example a connection interface, of the flexible sheet material to the electronic component and/or the location of the electronic component. If the first conductor is at least partially guided and/or laid in the sheet material, one end or section of the first conductor is led out of the sheet material at the location of the electronic component. The first conductor can be a conductor that is electrically insulated from the outside. In particular, the first conductor is stripped in the area of the electronic component. The first conductor and/or the laying of the first conductor is also specifically called the main line.

The first conductor has a first conductivity. The first conductivity is, for example, in the range of the conventional conductivity of metal wires, for example copper wires or silver wires, of strands or metal strips.

The electronic component is attached to the fabric. Preferably, the carrier and/or the circuit board of the component is attached to the fabric mechanically and/or materially. For example, the electronic component is glued, soldered, embroidered or riveted to the fabric. Alternatively and/or additionally, the component can be plugged into the fabric. In particular, the electronic component is attached to the free end of the first conductor. In particular, this location on the fabric is called the location of the electronic component. The electronic component can, for example, have bores and/or holes through which the component can be attached to the fabric, for example by embroidery, riveting or clips. In particular, the carrier of the electronic component can be designed as a textile, whereby the textile carrier of the component can, for example, be embroidered or sewn on directly.

The electronic component has at least one contact section, in particular two or more contact sections. The number of contact sections is particularly preferably even. The contact sections preferably comprise contact pads and/or are designed as metallizations. Pressure contact, in particular electrical contact, can be made by means of the contact sections, for example. The contact section is used in particular for electrically contacting the component with a current and/or voltage supply, in particular the first conductor. The electronic component can, for example, have conductor tracks from the contact section to the functional element of the electronic component. The conductor tracks are conventional, for example printed or etched, circuit boards. The contact sections are preferably arranged in an edge region of the electronic component, in particular the circuit board.

The at least one contact section is connected to the first conductor by means of an electrically conductive yarn. For example, the electrically conductive yarn is a pure metal yarn, a yarn with a metallic component, for example metallic tendon, a yarn coated with conductive material or a commingled yarn. The electrically conductive yarn is in particular knittable, woven and/or embroidered. The electrically conductive yarn is in particular designed to be flexible. The contacting of the first conductor is carried out by means of the electrically conductive yarn, for example the electrically conductive yarn forms an electrical connection between the contacting section and the stripped point of the first conductor or the first conductor in general. Alternatively and/or additionally, the first conductor can be pressed and/or pressed onto the contacting section by embroidering the electrically conductive yarn, so that the contacting section is directly contacted with the first conductor.

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

The invention is based on the consideration that supplying electronic components in smart textiles using the methods used to date does not allow the supply of higher currents. Electrically conductive yarns used to contact the electronic components in smart textiles usually have electrical conductivities that are several orders of magnitude lower than the electrical conductivity of conventional wires. If an electronic component is to be supplied with higher currents, high power losses have to be accepted due to the low electrical conductivity of the electrically conductive yarns used. On the other hand, conventional conductors, such as the first conductor, cannot be knitted, so that direct contact with circuit boards and/or components in the textile is not possible. The invention uses the consideration that in order to reduce power losses, a first conductor overcomes longer distances and the electronic component is contacted at the component location with the electrically conductive yarn, so that only low power losses occur here.

One embodiment of the invention provides that the connection of the first conductor with the contacting section is carried out by embroidering and/or sewing with the electrically conductive yarn. For embroidering and/or sewing, in particular conventional and/or industrial embroidery machines or sewing machines can be used. By embroidering and/or sewing, for example, the conductive yarn as the upper thread can press or press the first conductor onto the contact section or connect the contact section to the first conductor. For example, the electronic component, in particular the carrier, has bores and/or holes through which the electrically conductive yarn is guided and/or pulled, for example through and/or by means of a needle of the embroidery machine or sewing machine. This design is based on the idea of making contact between the first conductor and the contact section without soldering and in particular in an industrially and/or process-technically simple manner.

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

Optionally, it is provided that the first conductor is attached to the fabric. For example, the first conductor is attached completely to the fabric. Alternatively, the first conductor can be attached, for example, at least 70, preferably 80 and especially 90 percent outside and/or on the fabric. Preferably, the first conductor is sewn, embroidered and/or secured to the fabric in a captive manner using a stitch. Preferably, the first conductor is attached to the fabric using a fixing thread and/or fixing yarn, the fixing thread and/or the fixing yarn being an electrical insulator in particular. This design is based on the consideration that by arranging, laying and/or attaching it to the surface of the fabric, the first conductor can be guided intuitively and/or visually and a high degree of design freedom is provided. In particular, sewing is simple and inexpensive to implement in terms of process technology.

In particular, the first conductor has a free end. The free end is arranged and/or generated at the location and/or in the area of the electronic component. For example, the first conductor is cut off and/or stripped. The free end is arranged, for example, in and/or in the area of the contact section(s). The contacting and/or the The connection between the first conductor and the contacting section is made in particular by means of and/or at the free end of the first conductor.

It is particularly preferred that the first conductor is fastened in the component in a force-fitting, form-fitting and/or clamp-fitting manner, for example by means of a press fit. In particular, the first conductor is fastened in a force-fitting, form-fitting, clamp-fitting and/or press-fitting manner in and/or on the contact section. The force-fitting, form-fitting and/or clamp-fitting arrangement comprises and/or is formed in particular by the free end of the first conductor.

In particular, the force-fitting, form-fitting and/or clamp-fitting fastening and/or connection comprises at least one section and/or the entire contact section. The clamping connection, form-fitting, force-fitting and/or press-fitting is formed, for example, between the contact section, the first conductor and/or the conductive yarn. For example, the first conductor, in particular the free end, is pressed, clamped and/or inserted in a form-fitting and/or force-fitting manner into the contact section.

For example, the frictional connection, form-fitting connection, clamping connection and/or press-fitting connection is supported, closed and/or formed by the conductive yarn. For example, the conductive yarn is embroidered, sewn and/or wound in such a way that the conductive yarn presses and/or presses the first conductor onto the component, for example the contact section, or alternatively and/or additionally holds the first conductor in the component and/or specifically in the contact section in a form-fitting and/or force-fitting manner.

One embodiment of the invention provides that the component, in particular the carrier, has at least two, in particular exactly two, contacting sections. For example, the contacting sections comprise and/or are designed as bores and/or holes, in particular as bores and/or holes with metallization and/or contacting pad. The conductor, in particular the stripped end and/or the free end of the conductor, is inserted between the two contacting sections. The two electrical Contact sections are connected by the conductive yarn, for example as a loop or mesh. The electrical conductor lies on the carrier, for example, and between the two contact sections. In such an arrangement, the electrical conductor, in particular the free end, is limited, surrounded and/or held in a force-fitting manner by the carrier and the conductive yarn. By stitching the two contact sections together with the conductive yarn, a compressive and/or tensile force of the electrical conductor on the carrier can be achieved. In particular, the two contact sections can also be attached to the fabric using the conductive yarn and by stitching.

It is further provided that the electronic component, in particular the carrier, has at least one recess. For example, the recess is a recess in the carrier of the component. For example, the recess is designed as a depression, in particular as a complete opening, in a plan view of the carrier. Preferably, the recess has a rectangular contour in a plan view from above, designed in particular to accommodate the conductor. According to the invention, the first conductor, in particular the free end, is inserted or introduced into the recess and fastened therein. In particular, the recess is arranged between the two contact sections. By stitching and/or connecting the two contact sections using the conductive yarn, for example, the electrical conductor is pressed into the recess and/or onto the flat structure.

One embodiment of the invention provides that the recess is tunnel-shaped. For example, the recess is designed as a blind hole. Preferably, the drilling and/or advance direction of the tunnel-shaped recess is in the plane of the carrier. The tunnel-shaped recess is preferably closed in the circumferential direction, alternatively the tunnel-shaped recess can be interrupted in the circumferential direction and/or have recesses, for example one or more gaps. 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 The tunnel contact section is connected in particular electrically, for example via conductor tracks, to the functional element of the electronic component. By inserting, in particular pressing and/or keeping the electrical conductor in contact with the tunnel contact section, an electrical current and/or voltage supply to the component is enabled and/or realized.

Optionally, it is provided that the electronic component, the contact section, the tunnel contact section and/or the conductor end are embedded in a protective compound and/or matrix. For example, the protective compound and/or protective matrix is designed as a resin, as an adhesive or an insulating compound. For example, the protective compound is applied to the corresponding sections using a dispenser. It is particularly preferred that an adhesive compound, for example an electrically conductive plastic, is introduced onto the contact sections and/or into the recesses so that a mechanical connection is made there between the conductive yarn and the contact section and/or between the electrical conductor and the recess, in particular the tunnel contact section. This combines mechanical stabilization and electrical contacting. For example, embedding and/or gluing is carried out to protect against mechanical influences, chemical influences and/or environmental influences or weather influences such as dust and moisture.

It is particularly preferred that the electronic component, in particular the carrier, is glued to the sheet-like structure. In particular, the electronic component can be glued to the sheet-like structure using any adhesive, in particular an electrically insulating or electrically conductive adhesive, depending on the desired type of use.

In particular, the method can provide that the conductor is guided 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 an electrical conductor that is continued and/or arranged between two electrical conductors that are guided in parallel. In particular, no free ends are necessary here. In such a configuration, for example, series connections of electronic components can be made along one or more first conductors. The contact between the electronic component and the first conductor, which lies outside and/or parallel to the electronic component, is made here by the electrically conductive yarn, in particular by embroidery. For example, one or more loops or stitches are embroidered, with the electrical conductor and/or the contacting section being enclosed by this or these stitches and/or loops. In particular, it is provided that for an electrical conductor that is not inserted into a recess, in particular if the electrical conductor lies outside the carrier, the free end is corrugated or helical and/or bent to relieve tension and/or loss of the electrical conductor, so that the free end cannot slip out of a tab and/or loop of the fixing thread and thus cause an interruption in the power supply.

Another subject matter of the invention is an electronic arrangement. The electronic arrangement is in particular obtainable and/or the result of the method according to one of the preceding claims or as previously described. The electronic arrangement comprises a flexible sheet-like structure, in particular a textile, warp-knitted fabric, fleece or knit. Furthermore, the electronic arrangement comprises at least one electronic component or several electronic components. The electronic component is arranged and/or fastened on the flexible sheet-like structure. The first electrical conductor, in particular a conventional electrical wire, strand or metal strip, is in electrical contact with the electronic component. The electronic and/or electrical contact between the first conductor and the electronic component is made via an electrically conductive yarn. The electrically conductive yarn preferably has a lower electrical conductivity than the first conductor.

It is particularly preferred that the electronic arrangement and/or the fabric is designed as a textile, in particular a smart textile. It is particularly preferred that the electronic arrangement and/or the fabric forms an item of clothing, for example a glove, sock, outerwear or underwear.

Further advantages, effects and embodiments of the invention emerge from the attached figures and their description. They show:

• Figure 1 Top view of an electronic arrangement as an embodiment;
• Figure 2 Side view of the electronic arrangement from Figure 1 ;
• Figure 3 Side view of another embodiment of an electronic arrangement;
• Figure 4 Detail of a plan view of an alternative electronic arrangement not according to the invention.

Figure 1 shows a detail of a plan view of an electronic arrangement, obtainable from the method as previously described, as a first embodiment. The electronic arrangement comprises a flexible sheet-like structure 1. The flexible sheet-like structure 1 is, for example, a textile, whereby the textile can be cut to size, sewn, for example as a glove or a length of fabric. The sheet-like structure 1 is preferably a knitted fabric and/or a textile made of non-electrically conductive fibers and/or yarns, for example made of cotton or plastic fibers. The flexible sheet-like structure 1 can alternatively or additionally comprise electrically conductive yarns, for example for electrical shielding or electrical supply.

Two first conductors 2 are arranged on the flexible sheet-like structure 1. The first conductors 2 are designed as wires, for example copper wires. The conductors 2 can be electrically insulated or stripped from the outside. The first conductors 2 are guided on the flexible sheet-like structure 1. This can be done, for example, on an outside or inside of the sheet-like structure 1, in particular if a piece of clothing, for example a glove, is and/or will be made from it. The conductor 2 is preferably guided straight. The electrical conductor 2 is designed in particular to be rigid. The electrical conductor 2 has an electrical conductivity, wherein the electrical conductivity has a conductivity of a metal wire such as copper, silver or gold.

The first conductor 2 is attached to the fabric 1 by means of fixing threads 3. The fixing threads are preferably natural or synthetic threads, in particular electrically insulating ones. The conductor 2 is sewn and/or embroidered onto the fabric 1 by means of the fixing thread. In particular, the fixing thread, which is guided over the conductor 2, forms a loop and/or stitch that fastens and/or holds the conductor 2 on the fabric 1. The conductor 2 serves to supply current and/or voltage to the electrical component 4. The current and/or voltage supply is provided from a current and/or voltage source to the component 4.

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

The electrical component 4 has a carrier 6 and a functional element 7. The carrier 6 is designed, for example, as a circuit board. The carrier 6 can in particular also be designed as a textile and/or film-shaped carrier. Conductor tracks 8 are arranged on the carrier 6. The conductor tracks are used for contacting and/or supplying power to the functional element 7. The conductor track connects contacting sections 9 to the functional element 7. The contacting sections 9 are designed, for example, as contact pads. The contacting sections 9 have a hole, wherein the hole is at least partially metallized and/or electrically conductive. A conductive yarn 10 can be fed through the contacting sections 9.

A recess 11 is arranged between each contact section 9. The recess 11 is designed, for example, as a cutout and/or as an opening through the carrier 6.

The free end 5 of the electrical conductor 2 is inserted into the recesses 11. The recess protects the conductor 2 at least partially against slipping and/or sliding out within the plane of the carrier 6. In order to prevent the free end 5 of the conductor 2 from slipping out of In order to avoid damage to the recess 11, the electrically conductive yarn is guided through the contacting sections 9 and over the free end of the conductor 2. The electrically conductive yarn is guided downwards through the sheet-like structure 1, so that the electrically conductive yarn 10 holds the conductor, in particular the free end 5, in the recess in a captive manner and in particular presses it onto and/or against the sheet-like structure 1.

The electrical contact between the electrical conductor 3 and the electrical component 4 and in particular with the functional element 7 is made by the electrically conductive yarn 10. The connection is made between the contacting section 9 and the free end 5. This connection, in particular a very short connection length, is formed by the electrically conductive yarn 10. The electrically conductive yarn 10 has a lower conductivity than the first conductor 2. However, the power loss that occurs through the use of the electrically conductive yarn 10 is negligible over this short distance and can be minimized by forming several loops of the yarn 10 through the contacting sections 9 and over the free end 5. By using the conductor 2 with better conductivity, the power loss due to the current flow on the surface structure 1, which usually has to overcome longer distances, can be reduced.

Figure 2 shows a side view, in particular a sectional view, of the electronic arrangement of Figure 1 . It can be seen that the electrical conductor 2, in particular the free end, is held in the recess 11 in a captive, positive-locking and in particular force-locking manner. The conductor 2 is placed in the recess 11 and is delimited at the sides by the carrier 6. The position of the conductor 2 is delimited downwards by the flexible sheet-like structure 1. The recess 11 and/or the position of the conductor 2 are delimited upwards by the flexible and electrically conductive yarn 10. The yarn 10 is guided downwards through the sheet-like structure 1 so that the conductor 2 is pressed against the sheet-like structure 1. The electrical conductor 2 and the electrical component 4, in particular the functional element 7, are contacted by the conductive yarn 10. The yarn 10 forms an electrical connection between the conductor 2 and the contacting sections 9, which are designed here as holes with metallization.

Figure 3 shows another embodiment of an electronic arrangement in a cross section as Figure 2 . In contrast to Figure 2 the recess 11 is tunnel-shaped here, for example as a blind hole. In this exemplary embodiment, however, the blind hole is not delimited and is open to the underside, here the sheet-like structure 1. Alternatively, a delimitation to the sheet-like structure 1 can also be made here. The recess 11 is further delimited at the top by a carrier section 12. The conductor 2 is inserted or laid in the recess 11, with the electrically conductive yarn 10 being guided over the carrier section 12. The yarn is guided from below through the sheet-like structure 1 through the contacting sections 9, over the carrier section 12 through the contacting section 9 and downwards through the sheet-like structure 1. This enables the conductor 2 to be fixed in the recess 11 by fixing the carrier section 12. In particular, the carrier section 12, in particular the inside of the recess 11, is pressed and/or pressed against the conductor 2. For example, the upper side of the recess 11, also called the tunnel upper side, is designed to be electrically conductive and is pressed against the conductor 2 by the electrically conductive yarn, so that the contacting of conductors, in particular in addition to the contacting via the contact sections 9, takes place through this section.

Figure 4 shows an alternative, non-inventive, example of an electronic arrangement. In this arrangement, the electronic component, in particular the carrier, is the same or analogous to those from Figures 1, 2 and 3 formed. The first conductor 2 does not end at the location of the electronic component 4. The conductor 2 is guided further, in particular past the electronic component 4. Electrically conductive yarn 10 is used to electrically contact the component 4 and the conductor 2. A connection between the electrical conductor 2 and the contacting section 9 is formed by embroidering, sewing or looping. For example, a loop or stitch is formed by means of the electrical yarn 10, which is guided over the electrical conductor 2. This stitch or loop can be continued or interrupted by an understitch into the contacting section 9. Through this embroidering and/or sewing, the conductor 2 is fixed again to the surface structure 1 by the electrically conductive yarn 10, and The carrier 6 and the electronic component 4 are thereby also fixed to the surface structure 1.
