Description

The invention relates to a method for producing a cable. Furthermore, the invention relates to a corresponding cable set and a use of a jacket material for the production of the cable set.

Cable harnesses are used, for example, in the electrical system of a vehicle and have a plurality of cables, which typically connect different components together. The cables are often combined by means of a jacket structure, which fixes the position of the cable to each other and often also specifies their course. The jacket structure is produced, for example, in the context of an injection molding process in which the cables are inserted into a mold and encapsulated with a jacket material.

In principle, it is possible first to produce the shell material for the shell structure in the context of compounding as granules and then to supply this to an injection molding plant in order to form the shell structure. This is done at least twice a warming, namely once in the compounding, i. in the production of the actual jacket material, and a further time in the extrusion, in which the granules are heated and melted in order to process the jacket material at all. After compounding and before extrusion, the shell material is dried and cooled. As a result, the entire production of the cable sheath is very energy-consuming.

In the DE 10 2012 109 502 A1 is described a pasty PVC, which is prepared in such a way that results in a pasty, melt-like mass. This is achieved by a so-called direct compounding, in which PVC is fed as starting material to an extruder, where it is mixed with additives, especially a plasticizer, and at the same time tempered with a special temperature profile. In the course of tempering, gelling and curing of the cladding material already takes place since the softener completely diffuses into the PVC.

As sheath material, alternatively, a two-component system may be used, e.g. a polyurethane foam made by blending polyol and isocyanate. The cables are then placed in mold halves of the mold and the remaining cavity is sprayed with the polyurethane foam, which expands in this case and fills the cavity. The reaction of the two components of the two-component system also leads to a curing of the polyurethane foam. However, such two-component systems are complicated to handle, since the individual components must be stored separately. Upon contact, the components react immediately with each other, resulting in restrictions during manufacture, in particular the formation of the shell structure.

The invention has for its object to make the production of a cable set as simple and energy efficient. For this purpose, a simple, energy-efficient and improved method for producing a cable set, a cable set and a use of a suitable jacket material for the process should be specified.

The object is achieved by a method with the features of claim 1, by a harness with the features of claim 15 and by use with the features of claim 17. Advantageous embodiments, developments and variants are the subject of the dependent claims. The explanations in connection with the method apply mutatis mutandis to the harness and for use and vice versa.

The method is used to produce a cable set. In this case, several cables are surrounded by a common sheath structure, i. especially summarized. The shell structure is made of a pasty shell material, in particular PVC, wherein the shell material is cold mixed and is introduced with the cables in a mold and formed into the shell structure. Subsequently, the jacket material is cured. The curing is preferably carried out by supplying heat, i. by heating or tempering of the jacket material in the intended final form.

The invention is based in particular on the observation that conventional two-component systems for forming the sheath structure are expensive to handle, since the individual components are often hazardous to health, highly flammable, highly reactive or the like and therefore represent not insignificant sources of danger. Against this background, the use of less hazardous materials is desirable. Furthermore, two-component systems offer - due to the typically occurring in contact of the components reaction - little leeway in the molding and in particular also allow no subsequent shaping, ie the shape of the shell structure after demoulding, ie the removal from the mold, finally determined. These disadvantages are circumvented by the use of the special pasty shell material, since in this case the process steps of molding and curing are separated, whereby the production is much more flexible and easier. Furthermore, it is the jacket material advantageously to a ready mixed material, which is chemically stable for a long time and therefore easy to store.

Particularly preferred is the use of a PVC as a jacket material. Such a jacket material is based on pure PVC, to which various additives are mixed in order, inter alia, to maintain the paste-like consistency. The jacket material is then correspondingly safe to handle and, above all, in the ready-mixed composition long storable, i. especially over several months or even several years. In particular, the PVC has a long-term service temperature of up to about 125 ° C. Due to its material, PVC is also flame-retardant.

Furthermore, the invention is based in particular on the observation that the production of a sheath structure, in particular by using a one-component system such as PVC as a sheath material, by melting and extruding a granulate, which was previously prepared by compounding, is conventionally very energy-consuming. Overall, in each case at least two times a heating and a cooling is carried out, so that such a method is particularly energy and thus also costly. A core idea of the invention is now, in particular, to use as the cladding material a modified and improved material, which is advantageously produced beforehand in a cold mixing process. By this is meant that for the production of the cladding material no warming beyond the melt temperature of the cladding material and accordingly no subsequent cooling is needed, so that the cladding material is a cold mixed material. In other words, the jacket material is first cold mixed together from various material components or materials, which is understood to mean "cold" that is dispensed with a conventional temperature for melting during mixing. This is in contrast to a conventional compounding process in which first the various material components are heated to mix them together in a melt. In contrast, such an upstream heating is omitted for the purpose of mixing.

Furthermore, the shell material is mixed when mixed, i. when making the jacket material also not completely or not cured or gelled. The material components are thus at a temperature, also referred to as mixing temperature, mixed, which is less than a melting or curing temperature of the jacket material, preferably below 100 ° C. Usually at least two material components are mixed together, namely a plastic, e.g. PVC, and a plasticizer. In order to obtain a workable material, the plasticizer must at least partially penetrate into the plastic. In this case, it is particularly important when mixing that the temperature is high enough so that the plastic is disrupted and the plasticizer can penetrate, but small enough so that the material is not completely gelled or hardened and can be processed easily and flexibly. In principle, the optimum temperature during mixing depends on the choice of material and can therefore correspond, at least in principle, to the room temperature, room temperature in particular being understood to mean a temperature in the range from 15 to 25 ° C. Typically, however, the mixing temperature is above room temperature.

In the preferred use of PVC as a material component of this is suitably mixed at a mixing temperature in the range between 70 and 80 ° C, in particular at about 75 ° C with the other material components. This is based on the observation that the PVC forms molecules agglomerates, which must first be digested to incorporate the plasticizer. A mixed plasticizer penetrates only from a certain temperature, namely about 75 ° C, in the plastic, whereby the material components are then effectively mixed to form a paste or liquid. In particular, penetration of the plasticizer already corresponds to partial gelation of the jacket material, but does not yet constitute complete curing. Complete curing only takes place when the plasticizer has been completely absorbed by the PVC.

Due to the process, it is also possible under certain circumstances that even without active heating, a temperature increased relative to the room temperature is reached, in particular due to parasitic effects, such as friction. Such process-related heating will not be considered further below.

In contrast to the aforementioned material of DE 10 2012 109 502 A1 , which is produced by direct compounding, the present shell material when introduced into the mold, so not yet cured. As a result, the jacket material of pasty consistency, ie formed as a paste, and very easy to process. In addition, the jacket material is subsequently cured. Under pasty is understood in particular that the shell material is similar to a plasticine easily deformed under the action of force and remains in the form of no force, so is not liquid. Preferably, this has Jacket material has a viscosity in the range of 10 ^ 3 mPa · s to about 10 ^ 10 mPa · s.

A particular advantage of the invention is in particular that in the present case even in the production of the jacket material is dispensed with a tempering by the material components are mixed cold. The jacket material is thus produced overall in a pasty state and then also processed in this and only cured after the shell structure has been formed.

The jacket material is preferably cured by heating the cable harness after insertion of the jacket material by heating the molding tool. By such a direct heating of the mold curing of the cladding material is realized in a simple manner and without much effort. The curing thus takes place during manufacture within the mold. For example, when heated, the jacket material is heated to a temperature above the curing temperature, e.g. at 100 to 200 ° C, whereby the shell material gelled. However, the temperature is kept below a decomposition temperature in order not to damage the cables in particular.

By appropriate design and dimensioning of the heating during curing, it is expedient to set the hardness of the jacket and, in general, the bending flexibility of the jacket structure and thus of the cable set. Alternatively or additionally, the adjustment of the hardness and in general of the flexural flexibility takes place via the formulation of the shell material, in particular the polymers and / or plasticizers used.

In a first variant, complete curing takes place directly during manufacture of the cable set, i. the jacket material is completely cured and the cable set can be removed as a finished product the mold. Under certain circumstances, there is also a subsequent assembly of the cable set.

In a particularly advantageous second variant, the jacket material is cured by this after introduction into the mold and preferably in the mold, partially cured, for later final curing in the assembled state of the cable set and / or the intended use of the cable set. In the manufacture of the cable set thus no complete gelation of the jacket material, but only a partial gelation, so that the shell structure is only partially cured. Here, by "partially cured" is primarily understood a partial curing with respect to the hardness of the jacket material. In one variant, "partially cured" additionally means a partial spatial curing, wherein the shell material is then fully cured in places and partially hardened in places. Preferably, the shell material is partially cured by this is cured to 60 to 80%, more preferably 75%.

The partially cured jacket material also has a certain flexibility, whereby the assembly of the cable set is significantly simplified. The final cure, i. in particular complete curing then takes place advantageously only on the spot of the application, so that the curing of the shell structure takes place particularly accurately. For example, the shell structure has a number of retaining elements such as eyelets or the like, which can be easily attached to a suspension in only partially cured state and then hold particularly strong after final curing. An attachment to undercuts is made possible by the more flexible, since partially cured shell structure easier. The final curing can be done in the assembled state in a conventional manner by an explicit supply of heat. Particularly preferably, the final curing takes place alternatively or additionally during normal use, in particular by a near the harness set heat source, such as a motor in the engine compartment of a vehicle, so that the waste heat of the heat source is used for final curing in the assembled state and during normal use. In this way, energy is advantageously saved in the production of the cable set.

In the context of the present application, "curing" is also understood to mean "gelling", in particular in connection with PVC as the jacket material. To produce the cladding material, e.g. powdered PVC inter alia, mixed with a plasticizer, which lays between the individual PVC grains, whereby a pasty mass is produced. Upon curing, the plasticizer then gradually diffuses into the pvc grains and the mass becomes firmer, i. their viscosity is increased. Curing takes place by heating the jacket material to a temperature above a curing or melting temperature of the jacket material.

The pasty shell material is particularly easy to process below the curing temperature and especially at room temperature. The jacket material is at least kneadable or even pumpable, depending on the specific viscosity selected. The jacket material can therefore be processed cold. In a preferred embodiment, therefore, the jacket material is cold introduced into the mold, namely at a processing temperature which is lower than that Curing temperature, especially at room temperature. The special jacket material preferably used in the present method allows, in particular because of the special paste-like consistency, ie the viscosity, which is set decisively by the proportionally matched material components, a method without tempering of the jacket material. This results in the advantage that can be dispensed with an energy-intensive temperature control of the cladding material during its processing, ie when introduced into the mold and expediently also omitted. In the cold processing of the jacket material also the formation of the shell structure is advantageously separated from its curing. The processing temperature is defined in particular as the temperature of the jacket material in the mold when introduced into the same. An advantage of the cold processing is, in particular, that the cladding material is exposed to lower temperatures than in conventional production processes and is therefore advantageously less thermally stressed. Due to the reduced energy supply, a degeneration or even decomposition of the cladding material during manufacture of the cable set is effectively avoided. Overall, the shell material in the finished product has a lower thermal decomposition.

Since the method described is advantageously depressurized due to the paste-like consistency of the jacket material, the method is generally suitable for the production of cable harnesses with structures that are particularly sensitive in this respect, ie. Cable.

Overall, heating or heating advantageously takes place only for curing the shell material in the applied form, i. after shaping the shell structure. For the processing of the cladding material, for introducing the same and for its production, no or only the low heating or temperature control already described above in the context of mixing the individual material components is necessary, so that expediently dispensing with additional heating above the mixing and / or processing temperature , In an advantageous embodiment, therefore, the mold is operated cold when introducing the jacket material. Accordingly, only one heating step is carried out for the purpose of curing the cable sheath. The process thus has overall significantly reduced energy costs.

In a suitable embodiment, the cables are first inserted into the mold, whereupon the mold is closed and then the jacket material is introduced through a number of supply openings in the mold. In the closed mold then there are cavities, which are filled during insertion of the cladding material with this and which specify an outer contour of the shell structure. The cables are first fixed in the mold, for example by means of spacers or other holding elements in an intended end position and then surrounded with the jacket material. By using spacers or the like, in particular a uniform wall thickness of the shell structure is achieved and undesired slippage of the cables during introduction of the shell material is advantageously avoided.

In a further suitable embodiment, alternatively or additionally, the jacket material is first introduced into the molding tool and then the cables, which are at least partially inserted into the jacket material. The jacket material is thus introduced in front of the cables in the mold. This is possible in particular because of the kneadable sheath material. Due to the special consistency, the jacket material is preformed, so to speak, for example. Alternatively or additionally, the jacket material is formed by the cables are inserted into the jacket material and in particular pressed into it, so that the jacket material is at least partially displaced. Finally, the mold is closed and the shell structure finished shaped, in a particularly simple variant, but this is omitted.

The cables of the cable set are usually arranged branched. In a suitable embodiment, the shell structure has a number of branches. The cables are therefore arranged branched and form a network with several, in particular a plurality of endpoints. The shell structure is then branched accordingly and guides the individual cables along different paths.

The cable set, more specifically the sheath structure is preferably dimensionally stable, i. the cable set has a shape and the cables have an arrangement with respect to one another, which are fixed by the jacket structure. Such a dimensional stability is achieved in particular by the curing of the jacket material, which is usually not dimensionally stable in non-cured or only teilausgehärtetem state, but rather is plastically deformable.

The shaping of the shell structure preferably takes place by means of the molding tool. Alternatively or additionally, the shaping of the shell structure takes place in a suitable embodiment outside of the molding tool, in particular in a preforming step, so that at least a part of the Sheath structure or the entire shell structure is introduced as a number of preformed moldings in the mold. Thus, the shaping of the shell structure is at least partially decoupled from the production of the cable set advantageous. In this case, the jacket structure is preformed as a half-piece and, in the mold, then merely folded together and connected to the cables. As a result, the production of the cable set is much more flexible.

The cables usually each have a cable sheath, in general an outer sheath, which is necessarily in contact with the sheath material of the sheath structure during manufacture, but above all, and during normal operation of the cable set. Using different materials may result in unfavorable combinations. In the above-described use of a polyurethane foam for the shell structure results in particular in combination with an outer jacket made of PVC the disadvantage that the material of the outer shell over time the plasticizer is withdrawn and the outer shell becomes brittle and possibly even breaks. Advantageously, therefore, the cladding material is selected with respect to an outer cladding material from which the outer cladding is made, i. In a preferred embodiment, at least one of the cables has an outer sheath which is made of an outer sheath material, and the sheath material is equal to the outer sheath material. Particularly preferred is the use of PVC, since this is also particularly suitable for the production of outer shells. The PVC of the sheath structure and the PVC of the outer sheath do not necessarily have to have exactly the same composition, in particular with regard to possible additives, it is more important that both materials are basically PVC.

When using the same materials for the outer sheath of the cable and for the sheath structure also a particularly favorable seal against under certain circumstances penetrating media, in particular an improved longitudinal tightness is realized. This results in particular from the fact that the shell structure and the outer shell caked together due to the advantageous choice of material, i. a fabric bond is produced.

In principle, it is also conceivable that the jacket material is cured in a suitable embodiment by at least one of the cables is heated. In this embodiment, the hardening of the cladding material by heating the cladding material from the inside of at least one of the cables from significantly simplified. The heating of one of the cables is particularly suitable for simple conductors or wires as a cable.

As already mentioned above, the present method is essentially made possible by the pasty casing material. In this respect, the problem is solved in particular by the jacket material. This is preferably a mixture of 100 parts of a PVC, 25 to 100 parts of a plasticizer, 3 to 18 parts of a stabilizer and a filler. In the entire jacket material, the plasticizer has in particular a weight fraction of 15 to 50%, in particular up to 30%. As a result, an optimum viscosity for the described method is realized. Overall, the pasty shell material is then formed in particular in the manner of a plasticine and kneaded at room temperature. As plasticizers, for example, DPHP or DEHP are suitable and generally pthalate or Trimellitatweichmacher.

The PVC is suitably a mixture of E-PVC, i. emulsion polymerized PVC, and S-PVC, i. obtained by suspension polymerization PVC.

The proportion of plasticizer in the entire jacket material determines in particular the hardness and elongation at break of the cured shell. In a suitable embodiment, the cured shell has a range between Shore A hardness 70 and Shore D hardness 50. The elongation at break is suitably greater than 120%. In non-cured state, the plasticizer significantly determines the viscosity of the pasty shell material.

Preferably, the plasticizer is a high temperature plasticizer which is temperature resistant up to a temperature of 250 ° C, so that the cable set is advantageously suitable for high temperature applications. In particular, under high temperature use, operation is carried out at a temperature above 100 ° C and for a prolonged period of time, e.g. understood for several months.

In a preferred embodiment, the jacket material is free of comonomers, preferably free of both and thus particularly easy to handle. Comonomers often serve as plasticizers. In the embodiment mentioned, comonomers are then dispensed with as plasticizer and another plasticizer is used instead.

In a suitable alternative, the jacket material is admixed with a comonomer as plasticizer and the jacket material is free of a high-temperature plasticizer which is temperature-resistant up to a temperature of 250 ° C. Thus, a low temperature plasticizer is used.

In a suitable embodiment, the jacket material has at least one of the following substances: DPHP as plasticizer, a magnesium-aluminum-zinc system as stabilizer, chalk or coated chalk as filler. In a preferred embodiment, the jacket material comprises all of the substances mentioned. In a particularly preferred embodiment, the jacket material consists only of the substances mentioned and of PVC, in particular in the above-mentioned composition.

The magnesium-zinc-aluminum system is also generally referred to as a stabilizer package and consists in particular of magnesium, zinc, aluminum in combination with a lubricant, for example a stearate. Alternatively or additionally, calcium is added to the stabilizer.

In a suitable development, a foaming additive is or is added to the jacket material so that the jacket structure is foamed. By foaming the shell structure is particularly easy. The foaming additive is added to the cladding material, for example, when it is introduced into the mold and activated during assembly with the cladding material.

In a further suitable development, an acid scavenger is or is added to the jacket material to form a high-temperature-resistant jacket structure. In the operation of the cable set decomposition is then effectively prevented due to possibly released acid.

In principle, the paste-like casing material can also be produced with a particularly low viscosity by suitable choice of the material components in an advantageous variant, preferably in the range between 0.7 and 10 -3 mPa · s, ie. especially liquid rather than kneadable. As a result, the jacket material can be injected into the mold in a particularly simple manner, for example, in the context of an injection molding process. For such a method, the proportions of the individual components are then selected such that a jacket material with the appropriate viscosity results. For its promotion and processing, a feed pump is particularly suitable. The basic advantages, namely, above all, the energy savings in the production of the sheath material and in the manufacture of the cable set, remain intact.

Embodiments of the invention will be explained in more detail with reference to a drawing. In each case schematically show:

1 a cable set,

2a - 2d in each case a method step of a method for producing a cable set, and

2e a final curing during the intended use of the cable set.

In 1 is an embodiment of a cable set 2 shown. This has several cables 4 on which of a common shell structure 6 surrounded, ie in particular summarized. The cables 4 are arranged branched to each other and form a network. The shell structure is also corresponding 6 branches and forms branches 8th out. End are on the cable 4 each connections 10 attached, such as plugs or sockets to the harness 2 when used as intended, eg in the electrical system of a vehicle, to be connected to corresponding components. For clarity, not all cables are in the figures 4 and not all connections 10 explicitly provided with a reference numeral. For mounting has the sheath structure shown here 6 furthermore a number of retaining elements 12 on which each part of the shell structure 6 are and are made as moldings of the same material.

The coat structure 6 is made of a special pasty jacket material M. This jacket material M consists in the embodiment of several material components, namely a PVC, which is in particular a mixture E-PVC and S-PVC, a plasticizer, in particular DPHP, a stabilizer, in particular a magnesium-aluminum-zinc system with a lubricant, and a filler or coated chalk. In this case, each of the material components has a certain proportion in order to set a suitable viscosity, in particular in the range of 10 ^ 3 to 10 ^ 10 mPa · s. Thus, for 100 parts of PVC, the shell material M contains about 25 to 100 parts of the plasticizer, 3 to 18 parts of the stabilizer and 0 to 200 parts of the filler. These material components are cold to prepare the jacket material M, that is mixed together at a mixing temperature. This is here about 75 ° C and in any case is less than the curing temperature, so that there is no complete curing or gelling and the shell material M is present as pasty and very easy to process mass. Only later, the jacket material M is heated and cured.

Individual steps of a cable harness manufacturing process 2 are in the 2a to 2d shown. It shows 2a the cables 4 in their intended arrangement. On a representation of connections 10 was omitted here, these are either before or after forming the shell structure 6 as part of a cable assembly 4 appropriate. 2 B shows a mold 14 for shaping the shell structure 6 , In a suitable embodiment of the method, the cables 4 first as in 2c shown in the mold 14 inserted. Then the mold becomes 14 closed and the jacket material M is through a number of supply openings 16 in the mold 14 introduced, in 2c indicated by an arrow. This is basically similar to an injection molding process, which is made possible here by the special pasty consistency of the jacket material M. In the closed mold 14 are then cavities, which are filled during insertion of the jacket material M with this and which an outer contour of the shell structure 6 pretend. The shaping of the shell structure 6 takes place here by means of the mold 14 , The cables 4 be in the mold 14 For example, fixed by means not shown spacers in an intended end position to a uniform wall thickness of the shell structure 6 to achieve and accidental slippage of the cables 4 to avoid when introducing the jacket material M.

In a variant, not shown, the jacket material M additionally or alternatively in front of the cables 4 in the mold 14 introduced and the cables 4 are then then put into the jacket material M or pressed into it.

Since the jacket material M has a pasty consistency, this is also processed cold, ie in the mold 14 introduced and shaped there. By "cold" it is understood that during processing, preferably no additional temperature control of the jacket material M takes place, but at least the jacket material is processed at a processing temperature which is lower than the curing temperature, in particular at room temperature. The pasty consistency of the jacket material M also allows a simple and above all unpressurized processing, which also takes place here accordingly.

In the embodiment shown, the cables 4 in each case an unspecified outer sheath which is in contact with the sheath material M. In order to achieve the best possible material compatibility, the jacket material M and the material from which the outer shells are made, are the same here, in particular in each case a PVC.

After introducing the jacket material M and shaping the shell structure 6 the jacket material M is cured so that the in 2d shown dimensionally stable cable set 2 results. For curing, in the embodiment shown, the mold 14 to the curing temperature or above, for example, between 100 and 200 ° C, heated after the jacket material M was introduced. This results in particular a gelation of the PVC used.

Basically, a complete curing in the context of the production of the cable set 2 possible. In a particularly expedient variant, however, the jacket material M is cured by this is only partially cured, for later final curing in the assembled state of the cable set 2 and / or the intended use of the cable set 2 , In the production of the cable set 2 then takes place no complete gelation of the shell material M, but only a partial gelation, so that the shell structure 6 only partially hardened. For example, the retaining elements can be 12 in only partially hardened condition easier to attach to a suspension, not shown, for example, in a vehicle and then hold after final hardening particularly strong, causing the assembly of the cable set 2 is significantly simplified. The final curing, which in one variant is a complete curing, then advantageously takes place in place of the application, so that the curing of the shell structure 6 especially made to fit. This is in 2e shown in which the harness 2 is mounted in a vehicle not shown in detail, close to a heat source 18 , here an engine of the vehicle. In this case, the harness is eg by means of the holding elements 12 attached to the engine. The final curing then takes place during the intended use of the cable set 2 by using the waste heat of the heat source 18 ,
