Definitions
- the present invention relates to a ribbon cable, in particular a clock spring, with at least two electrical conductors, the electrical conductors in an insulating sleeve are embedded and the insulating sleeve has a substantially rectangular cross section and the ribbon cable can be wound up, so that two of the Surfaces of the insulating sleeve come to lie on one another.
- Clock springs are for use in motor vehicles known. They serve a reliable electrical Connection between a rotating steering wheel and a relative to the motor vehicle stationary steering wheel mount create.
- the one used for the electrical connection Ladder is also known as a clock spring.
- This Clock spring is coil-shaped in a housing between the Steering wheel and the steering wheel holder coiled and such dimensioned that the steering wheel one in both directions can perform a complete rotation of several revolutions, without this rotation path through the length of the clock spring is limited.
- Such arrangements are, for example, from known from DE 195 34 655 A1 and DE 198 37 076 A1.
- Cavities are formed by the surface structure, in condensed moisture can. This ensures that the aforementioned Adhesive effect between the surfaces of the insulating sleeve is significantly reduced.
- the surface structure according to the invention causes the Surfaces of the insulating sleeve only in parts of the Total area come to lie on each other. This will capillary forces are also reduced or avoided entirely. Consequently, an adhesive effect can only be in these Sub-areas arise.
- a Ribbon cable a first surface (top) with a Surface structure and a second, flat surface (Bottom) on. It is also possible that the top and the underside has a surface structure.
- the surface structure advantageous that the surface is uneven, and for example, has depressions or recesses which are formed in this surface. It is special advantageous that the recesses or recesses in Longitudinal direction of the electrical conductors. This has the main advantage of using the clock spring of extrusion processes can be made, wherein the recesses or recesses are part of the endless profile of the ribbon cable.
- the depressions or Recesses are also funnel-shaped or spherical are.
- This form of training has the advantage that the Surfaces of the insulating sleeve only in the between the Recesses or recesses formed with edge areas the contact surface of the insulating sleeve come. This can greatly reduce the contact area become.
- the protrusions are in the surface of the insulating sleeve Projections formed. Even through these protrusions the contact area between the superimposed ones Surfaces of the insulating sleeve of the ribbon cable strong be reduced.
- the protrusions are in Form of pimples or ridges formed in cross section
- the protrusions are formed as nubs Contact area from those areas of the knobs that in relation to a knob in the middle and therefore most elevated are.
- this can Ribbon cables using extrusion processes be produced if the beads in the longitudinal direction of the electrical conductors.
- the beads can be part the common insulating sleeve of several electrical conductors be stamped into the insulating sleeve. It is also possible, that the beads are formed by the electrical conductors each have their own electrical Have insulation that are in the longitudinal direction with each other are welded. In such an embodiment forms thus part of the insulating sleeve of an electrical conductor a bead.
- the beads can be transverse to the longitudinal direction of the electrical conductors. Even through one Embodiment can the contact area between the superimposed surfaces of the ribbon cable be reduced. This is also possible if the beads run at an angle between the longitudinal and the Transverse direction of the electrical conductor is formed.
- the beads are So on the top and bottom of the ribbon cable arranged. Touch when winding the ribbon cable the beads on a top face with the beads on one Underside of an adjacent winding only in Crossing points. This arrangement also ensures that Contact area between adjacent surfaces reduced.
- the ribbon cable 2 has a Substantially rectangular cross section on that of an essentially flat underside 4, an uneven one Top 6 and a first boundary 8 and one second boundary 10 is limited.
- the ribbon cable 2 has insulating material 12 that as a sheath for the in Longitudinal direction of the ribbon cable 2 extending electrical conductor 14 is used.
- Embodiment are a total of five electrical conductors shown.
- In the uneven top 6 are total three substantially rectangular depressions 16 introduced, which is in the longitudinal direction of the ribbon cable 2 extend.
- the depressions 16 serve as a receiving space for moisture that is due to a Temperature changes from a cold to a warm state from moist ambient air on the ribbon cable 2 reflected. This wet precipitation can occur in the Wells 16 are added.
- the uneven top 6 has elevation surfaces 18 which as a support surface for a not shown in Figure 1 serve flat bottom 4 of the same ribbon cable 2, which is wound in the form of a snail or spiral.
- FIG. 2 shows an embodiment of a ribbon cable 20, the left hand in a top view and the right hand in a cross section is shown.
- the ribbon cable 20 is delimited by a flat underside 24, an uneven one Top side 26 and first and second borders 28 and 30.
- the ribbon cable 20 consists of insulating material 32 for in this embedded electrical conductor 34.
- In the top 26 of the ribbon cable 20 are spherical depressions 36 arranged in which there is precipitated moisture can collect.
- the ribbon cable shown in Figure 2 comes with Rewinding with raised areas 38 in the top 26 a first winding with the underside 24 of a second Winding in contact.
- the whole from the survey areas 38 formed surface is opposite to that on the underside 24 formed area small. This will make the danger reduced that the ribbon cable 20 when precipitation of Moisture sticks to an adjacent winding.
- FIG 3 is a designated 40 in total Ribbon cable on the left in a top view and shown on the right in a cross section.
- the Ribbon cable 40 has a substantially flat Bottom 44, an uneven top 46 and one Borders 48 and 50 respectively.
- the ribbon cable 40 consists of an insulating material 52 into the electrical conductor 54 are embedded.
- On the top 46 of the ribbon cable 40 are knob-shaped projections or elevations 56 intended.
- the knobs 56 have a part-circular shape Cross section on and limit water collection rooms 58. In In these rooms, this can be done by condensing water formed in humid air, which prevents will that the top 46 of a first winding of the Ribbon cable 40 on the underside 44 of an adjacent one Winding sticks.
- the ribbon cable 60 shown in Figure 4 has one Similar structure to that shown in Figure 3 Ribbon cable 40 on. However, the ribbon cable 60 has not spherical segment-shaped knobs 56, but honeycomb-shaped Pimples 76 on. There are water collecting spaces between the knobs 76 78 trained.
- FIG 5 is a top view on the left and right hand a cross section of a ribbon cable 80 is shown.
- the Ribbon cable 80 has a total of three beads 96 that in the longitudinal direction of the electrical conductor 94 of the Ribbon cable 80 run.
- the ridges 96 have one partly circular cross-section. Are between them Water collection rooms 98 are also formed in Longitudinal direction of the electrical conductor 94 of the Ribbon cable 80 run.
- the ribbon cable 120 shown in Figure 7 is in the in Figure 7 lower drawing in a plan view and in in Figure 7 top drawing along the cross section B-B shown.
- the ribbon cable 120 has a cross section trapezoidal beads 136 which are inclined to 139 designated longitudinal direction of the in the ribbon cable 120 trending electrical conductor. Between trapezoidal beads 136 are water collection spaces 138 educated.
- the ribbon cable 140 shown in Figure 8 is on the left in the top drawing in a top view, in the middle drawing in a side view and in the bottom drawing shown in a bottom view.
- Figure 8 on the right is a cross section along the line C-C shown according to the drawing on the left.
- the Ribbon cable 140 has both on the bottom 144 and 146 beads on the top, each at an angle to the longitudinal direction of the ribbon cable designated 159 140 run.
- On top 146 there are beads 156 and 144 beads 155 arranged on the underside. Between the Top 146 and bottom 144 located Insulating material 152 is used to hold electrical Ladders 154.
- FIG Surfaces of adjacent windings only in Crossing areas 157 of the beads 155 and 156 for support.
