For the electrically conductive mesh 26 or the electrically conductive network 26 however, other metals such as stainless steel, galvanized steel, pure steel or galvanized copper may also be used. It goes without saying that, in addition, other metals and / or further alloys can be used.

The 3A to 3G each show in a schematic way a method for electrically connecting an electrically conductive element with an electrically conductive mesh 26 or an electrically conductive network 26 using a crimped connection 52 , Even if that in the 3A to 3G shown electrically conductive element a cable 44 or a line 44 is, it goes without saying that this also other electrically conductive elements can be used. As it is in 3A can be seen contains the conductive mesh 26 or the leading network 26 a first section 40 that is different from a second section 42 extends. The second section 42 extends along a longitudinal axis L, while the first section 40 extends along an axis T, which extends transversely to the axis L, wherein the axis T can be oriented in particular perpendicular to the longitudinal axis L. In some embodiments, the conductive mesh is 26 or the leading network 26 flat, ie not in the shape of a braided tube. In the embodiment of 3A is the second section 42 larger than the first section 40 , where the first section 40 the conductive or conductive network or network 26 has a rectangular shape, for example, as a rectangular strip of the conductive mesh 26 or the leading network 26 , In addition, there is the first section 40 in the embodiment of 3A in the same plane as the rest of the second section 42 , Even if in 3A only a small section of the second section 42 is shown, it goes without saying that the second section 42 can be dimensioned so that he defined areas of the steering wheel core 22 can cover. In a particular embodiment, the second section is 42 an elongated strip whose length is roughly equal to the circumference of the steering wheel 12 matches.

The first paragraph 40 is in relation to the second section 42 folded or folded on the second section or folded ( 3B ). In one embodiment, the convolution directs the first section 40 at an angle of 90 ° to the second section 42 out. The first paragraph 40 is twisted or twisted, creating a first twisted network section 40 ' or a first twisted braid section 40 ' is trained ( 3C ). A cable 44 that has a shielded section 46 is adjacent to the twisted braid section 40 ' or the network area 40 ' positioned ( 3D ). Either the cable 44 or the twisted braid section 40 ' or network area 40 ' are around the other part - the twisted braid section 40 ' or the cable 44 - wound around, creating a twisted or twisted connection 48 is trained ( 3E ). In some embodiments, the cable 44 and the twisted braid section 40 ' or twisted network area 40 ' twisted together or wrapped around each other, creating the twisted connection 48 is trained. In other embodiments, only either the cable are each 44 or the twisted braid section 40 ' around the other part - the twisted mesh section 40 ' or the cable 44 - wrapped around.

A crimp connector 50 can in the 3E direction shown on the twisted connection 48 slide and then around the twisted connection 48 squeezed, causing the crimp 52 is formed ( 3F ). Optionally, the crimp connection 52 on the second section 42 of the conductive mesh 26 or the leading network 26 be folded back or folded back, where also a cover 54 over the top of the crimp connection 52 be applied can, in this way, the crimp connection 52 between the cover 54 and the second section 42 of the conductive mesh 26 encapsulate ( 3G ). The cover 54 can be used as a protective layer for the crimp connection 52 serve. The application of the cover 54 can be done using an adhesive such as hot glue (for example from a hot glue gun). The cover 54 For example, it can be either towards the steering wheel core 22 or steering wheel rim 22 be oriented or point away from it. The cover 54 can thus also serve as a protective, adhesive coating.

In one embodiment or in several embodiments, the line 44 or the cable 44 formed by a wire or a cable with the dimension "22 American wire gauge (AWG)". This means line dimensions that can lie in a range of about 0.5 to 0.7 mm in diameter (22 AWG corresponds to exactly 0.644 mm cable diameter, corresponding to 0.326 mm ² cable cross-section). However, other suitable cable dimensions or line strengths may be used instead. The diameter or the strength of the pipe 44 and the width of the first section 40 (For example, measured in a direction parallel to the axis L) can be chosen so that so that a desired size dimension of the crimp can be ensured (ie, a desired cross-sectional dimension within the crimp connector 50 ). In one embodiment or in several embodiments, a thickness or width of the first section 40 (Measured in a direction parallel to the axis L) 15 mm or any value between 10 mm and 20 mm. In the same embodiment or in several or other embodiments, the length of the first section 40 (Measured along the axis T) about 20 mm or 30 mm, or may take any value between 15 mm and 35 mm. It will be understood by those skilled in the art that these values are to be understood as exemplary only, and that other useful strengths, cross-sectional dimensions and length values for the first section 40 can be chosen and used.

The 4A schematically shows an exemplary crimp connector 50 before his bruising, and the 4B schematically shows the crimp connector shown by way of example 50 ' after his bruising. Like the 4B shows, deforms the pinch of the crimp connector 50 this crimp connector 50 and thus secures the twisted connection 48 , The 4B also shows by way of example in which state the first section 40 and the cable 44 after crushing or after the production of the crimp connection 52 can be located. In the embodiment of 4A , a state before crushing or before the production of the crimp connection 52 shows, the crimp connector 50 a cylindrical contour. It goes without saying for the person skilled in the art that other crimp connectors can also be used instead of the crimped connector shown.

The flowchart or flowchart of 5 illustrates a method 100 for the electrical connection of a conductive element (for example a line 44 or a cable 44 ) with an electrically conductive mesh 26 using a crimped connection or a crimp connection 52 , A first section 40 of the electrically conductive mesh 26 that is from the second section 42 of the electrically conductive mesh 26 is used to form a twisted braid section 40 ' twisted (block 102 ). Either the electrically conductive element or the twisted braid section 40 ' are around the other part - the twisted braid section 40 ' or the electrically conductive element - wrapped around, creating a twisted connection 48 is formed (block 104 ). A crimp connector 50 is over the twisted connection 48 squeezed, creating a crimped connection or a crimp connection 52 is formed (block 106 ).

In one embodiment, the electrically conductive element is a cable 44 , and twisting the block 104 includes twisting the cable 44 and the twisted mesh section 40 ' each around each other or each other. However, it can also be provided in other variants that either the cable 44 or the twisted braid section 40 ' around the other part - the twisted mesh section 40 ' or the cable 44 - are wrapped around.

In some embodiments of the in 5 shown method 100 can the first section 40 of the conductive mesh 26 together with the crimp connection 52 on the second section 42 of the conductive mesh 26 be folded. In some of these embodiments, a cover 54 on the bruised first section 40 of the conductive mesh 26 be applied, thus the crimp 52 between the cover 54 and the second section 42 of the conductive mesh 26 and also as a protective layer for the crimp connection 52 serves (see the 3G ).

As already related to the 2 has been explained, the second section 42 of the conductive mesh 26 or the connecting network 26 forming part of a steering wheel assembly that houses the steering wheel core 22 and those around the steering wheel core 22 wrapped around or around it applied aesthetically pleasing cover 24 includes. In some of these embodiments, the second section 42 the conductive mesh or network 26 around the steering wheel core 22 be wrapped around, so that he at least partially between the steering wheel core 22 and the aesthetically pleasing cover 24 located. In some embodiments, the second section is 42 the conductive mesh or network 26 shaped in a way that it has certain areas of the steering wheel core 22 covers.

In some embodiments, there is a capacitive sensor (this may, for example, a sensor line 36 or sensor cabling 36 be) between the visually appealing and the aesthetically effective cover 24 and the second section 42 of the conductive mesh 26 , wherein there is also a heating element (this may, for example, a heating element wiring or wiring 27 be) between the steering wheel core 22 and the second section 42 of the conductive network or mesh 26 can be located. In some embodiments, the second section is 42 of the conductive network or mesh 26 designed as EMI shielding, so as to shield the electromagnetic stray radiation (EMI) capacitive sensor of the heating element. In some embodiments, however, can also be provided that the steering wheel 12 has no such electrical heating element, so no heating element wiring 27 integrated there.

The 6 illustrates an embodiment of an electrically conductive braid 26 , which is here designed as a knitted mesh, which interconnected loops 62 or stitches in a row 64 includes, each around foot areas 66 the loops 67 or stitches in adjacent rows 68 wrap. The loops 62 and 67 in different rows 64 respectively. 68 of the 6 can move within the same plane relative to each other without causing the mesh 26 is disturbed, whereby the knitted mesh becomes elastic in two directions. In one embodiment or in several embodiments, each loop acts as a small spring when it is acted upon by elastically acting tensile forces or compressive forces. When this spring is not stressed beyond its maximum elongation, it returns to its original shape as soon as the tensile or compressive forces acting on it are eliminated. In one embodiment or in several embodiments, the conductive network 26 may be formed by conduits whose diameter is in the range of 0.0035 inches to 0.2 inches (roughly equivalent to a range of 0.1 mm to 5 mm) or from 0.0005 inches to 0.0350 inches (roughly equivalent to one inch) Range of 0.01 mm to 0.9 mm). Of course, the person skilled in the art knows that other braid variants can also be used, for example woven braids or woven networks.

By using the crimped connection 52 for producing the electrically conductive connection between the line 44 and the conductive mesh 26 Instead of a soldered connection, reliable and reproducible results can be achieved, which can be advantageously used for steering wheel configurations and / or steering wheel assemblies. When the bruised connection 52 for example, below the aesthetically effective cover 24 located, can the crushed connection 52 be arranged in such a way that it forms a narrow profile that of the hands 20 a driver 18 hardly or less noticeable than would be the case if a soldered connection is equipped with large accumulations of solder.

The invention has been described with reference to exemplary or preferred embodiments. However, it will be apparent to one skilled in the art and it will be apparent that modifications or changes may be made to the invention without departing from the scope of the following claims. For this reason, the following claims should be read in terms of their actual scope and actual content.
