Holding device for fastening a strand-shaped body on a

flat component

The invention relates to a holding device for fastening a strand-shaped body, in particular a cable or a line, to a flat component having a rough surface structure, e.g. a panel in an automobile interior, by means of a Velcro connection.

The fastening of an electrical cable to a lining part for the interior lining of a vehicle using a Velcro connection is known, for example, from DE 196 23 575 A1. In this case, the cable is wrapped with a sheath or with sleeves made of a nonwoven material, which creates a detachable adhesive connection with a Velcro strip arranged along the cable on the lining part. The Velcro connection is formed exclusively in a narrow strip on the sheath or sleeve surface along the extension of the cable.

There are many different methods for attaching cables and wires to flat bodies in the automotive supply industry. These methods have specific disadvantages and limitations that hinder either the cable manufacturer or the user. There is therefore no known method that easily meets all the requirements for attaching a cable or wire to a flat body.

Today, there are a number of panel components in automobiles, such as the roof liner and the door panels, which are installed inside the car. These panels have a curved panel shape and often carry electrical functional groups, such as switches and lights. Accordingly, the electrical supply lines to these functional groups must be fixed to the back of the panel so that during the vehicle operation,

&igr; drive no rattling noise can occur. Some selected inadequate

2 fastening methods are shown below.

4 The fastening of classic round conductor bundles is usually done with hot glue

5. For this purpose, a hot adhesive bead is applied and the round

6 bundles are pressed into this bead. The adhesive cools and solidifies after

7 several minutes and holds the round conductor bundle permanently on the panel. &bgr; The dripping time of the hot glue severely limits the fastening process.

9 The conductor bundle must be placed in this area immediately after applying the adhesive bead.

10. Until the next panel is processed, the

11 Wait for the hot glue of the previous panel to cool down.

13 Flat conductors made of flexible printed circuit boards, which are called Flexible Printed Circuits - FPC

&eegr; are often attached with textile adhesive tape. The very

is flat FPC is placed on the back of the panel and the adhesive tape in the same

16 direction over the FPC and pressed into place. The connection between

17 the adhesive tape and the panel is not optimal because the back of the panel

19 come off when forces are applied to the ends of the tape.

20 fibers from the cladding composite. The long-term stability of this adhesive tape

21 Connection is not available.

23 For the flat conductors, which are often produced by extrusion and sold as flexible

24 Flat Cable - FFC, the best fastening to date is with a

25 Velcro fastener is achieved. During the extrusion or shortly after, the Velcro

26 fastener tape is applied to one side of the FFC. On the other hand, the

27 Panel components during production with the loops on the back

28 side, which is the counterpart to the Velcro. The FFC with

29 Velcro loses a large part of its flat design because the Velcro leads to such an increase in thickness. The processing of the FFC with the Velcro

31 fastening tape is complicated because the Velcro tape on fibrous surfaces, such as

32 clothing, and when laying the FFC on the cladding

&igr; component a subsequent displacement of the FFC only after loosening the Velcro

2 closure is possible.

4 Flat conductors can also be ribbon cables, which contain round conductor strands, which

5 are coated with plastic together in a band structure and used, for example, in the &bgr; personal computer as bus connections.

8 The present invention is based on the object of providing a simple fastening

9 of a strand-like body, in particular a cable or a line, on

10 a flat component without the described disadvantages of the

11 State of the art.

13 This object is achieved according to the invention by a holding device with the

&eegr; Features of claim 1. Here, a Velcro connection between a

15 a rough surface structure having a flat component, such as a

16 clothing in an automobile interior, and a strand-shaped body, such as a cable or a line, by means of a Velcro connection. The

18 on the rough surface structure, especially a textile surface

19 structure, the strand-like body lying on the flat component is provided with a

20 Velcro tape, which is used exclusively in a strand-shaped

21 Body protruding edge area a fully developed Velcro structure

22. Outside the edge area, i.e. especially in the strand-shaped

23 area covering the body, the Velcro structure is not present or not

24 fully developed, for example deformed and thus flatter than in the edge

25 area.

27 This design of the Velcro connection achieves the following advantages:

28 · the process time of the fastening can be kept variable,

29 · the fastening is long-term secure,

so · the flat design of FPC, FFC, ribbon cable is almost retained,

31 · During processing, no adhesion of Velcro to fibrous

32 surfaces in the vicinity of the components,

11 cable, has a surface structure generally referred to as rough, which

12 for example, by flocking with fibers or by an adhesive textile tape. Any surface structure that can be used to form a Velcro

14 connection is used, is referred to as “rough surface

15 structure". The flat component can be in the area of the rough surface

16 structure or the Velcro tape, for example, hook or mushroom-shaped structures

19 The Velcro strip is preferably perforated in the area of the support surface.

21 door on the underside, i.e. on the side facing the flat component,

22, the Velcro tape according to a further preferred embodiment also has a

23 Velcro structure on the top side. This Velcro trace, which

24 either in the form of a continuous band or in the form of individual islands,

2s can be designed as a dotted line, is preferably in the edge area

26 of the Velcro tape. This means that neither the strength of the Velcro tape in the

27 area of the support surface, nor does it affect heat dissipation.

&igr; According to a preferred further development, the Velcro tape is a Velcro tape composite

9 ches from the Velcro structures, such as hooks or loops, of the flat

10 component and/or the Velcro strip can be easily penetrated. In this

11 case, the net-like band can be placed around the strand-like body and

12 two-layered on the flat component through the Velcro strip on

13 be held in place. The net-like design of the tape is, however, also advantageous for Velcro strips arranged on both sides, since a wide

26 For a particularly strong protective effect, the tape can be used in the area of the

12. This area 6 of the Velcro can have additional holes or other

13 punched-outs 7, commonly referred to as breakthroughs, in order to

µm to enable better heat transfer from the flat conductor 2 to the environment.

15 In addition, the Velcro 3 on the top can create some loops in narrow

16 tracks, so-called Velcro tracks 8.

22 Velcro rolls thus hold themselves independently and roll 9 remains stable.

23 In addition, no hooks 5 point outwards, so that the roller 9 does not catch on fibrous

7 of the Velcro strip 3. The scooter consists of a handle 20, a holder 21 for

&bgr; the replaceable covering component Velcro roll 9, a deflection and pressure

9 roller 22, a knife structure 23 and two movable jaws 24, which are connected to a

10 trigger 25 can be moved. The Velcro roller 19 without the jaws 24

11 works like a conventional tape dispenser. This function is generally

12 and is therefore not explained in detail here. The jaws 24 conceal the

13 Velcro tape 3, so that the hooks 5 cannot stick to fibrous surfaces in the surrounding area. Only when the trigger 25 is pulled against the spring 26 do the jaws 24 move towards the middle of the roll 9 and release the hooks 5 of the Velcro tape 3.
