Moisture-Sealing Wire Guide Assembly, Insertion Item Therefor and Method of Producing a Wet-Sealing Wire Guide Assembly

Field of the invention

The invention relates to a moisture-sealed cable routing arrangement, in particular for motor vehicles, can be passed through the cable strings with multiple lines, such as electrical cables, optical fibers or pneumatic lines through walls, wherein on one side of the wall moisture may occur, while on the other side of the wall is undesirable. For example, the invention also relates to cable routing arrangements in which moisture from electrical contacts or interiors should be kept away, even if there is oppression on the side facing away from the moisture. The invention further relates to an insert element for such a cable guide arrangement and to a method for producing such a cable guide arrangement.

For example, in a vehicle, it is necessary that, at certain locations, a wire harness be inserted from the outside of the vehicle into the interior, i. H. for example, in the passenger compartment, is performed. In this case, moisture or other undesired liquid or gaseous media may possibly enter the area to be kept dry at these passage openings. In addition, in areas where the wiring harness runs in the parts of the vehicle that are not specifically protected against ingress of moisture, moisture, such as rainwater, may run along the wiring harness, or along the single conductors of that wiring harness, and into, for example, the passenger compartment penetrate when the transition between the passenger compartment and the non-moisture sealed area of the vehicle is not sufficiently sealed. For example, the ever-present moisture can lead to corrosion problems on the vehicle or be undesirable in certain areas of the vehicle for reasons of comfort.

State of the art

For sealing such passage areas in walls, various arrangements are provided, usually on the wiring harness, on single or multiple cables, to form cable strands which are usually made up of a plurality of • (• (♦ ··· · 2 ··· · ♦ · ··· »

Single conductors consist of passing through walls, openings, plugs or the like, while providing a seal.

From DE 34 31 617 Al an arrangement is known, with which a plurality of lines can be passed through a wall, wherein on one side of the wall, a moisture-proof space to be provided. For this purpose, the individual conductors are inserted into a tubular element made of rubber, wherein the individual conductors are surrounded by foam material, which fills the blanket cylinder. The rubber cylinder in turn is provided with recordings, by means of which he can be used in the wall in a moisture-proof manner. Each individual conductor is encompassed by the plastic material and filled the entire interior of the cylindrical rubber element.

From DE 37 17 296 C2 a capping for a lightwave artery is known. The individual optical waveguides are accommodated in a cylindrical core sheath, wherein a seal at the end of the core sheath is effected by a capping by means of a solid, non-liquid flowable mass in the processing state and the mass in which the optical waveguides are embedded, is elastic. The area in which the mass is provided is enclosed by a cylindrical shaped body, which consists of two parts, which in turn is covered on the outside by a shrink tube or itself consists of a shrinkable material.

Inside the capping can be arranged a core with recesses. In the individual recesses then the individual optical fibers can be inserted before the elastic mass is introduced. The flowable mass is introduced through a filling opening in the wall of the buffer tube, so that it continues from the buffer tube inwardly into the optical waveguide arrangement.

Finally, a grommet for a cable bundle is known from US Pat. No. 6,010,134, in which the conductors of the cable bundle are arranged in a cylindrical body, which may consist of two halves connected by a film hinge. A sealant is introduced in the area between the conductors and the cylindrical element.

Furthermore, a construction for a watertight conductor bushing is known from EP 635 921 A1. In this case, a flowable sealant is introduced by means of a tube which has pores at its one end region in a central region of a cable bundle. The sealant is introduced into the tube and distributed inside the cable bundle, since the tube is correspondingly inserted into the interior of the cable bundle during the sealing process, so that. *** " the flowable sealant can escape from the pores of the tube and seal the area between the individual conductors of a cable bundle.

For sealing a cable bushing through a sealing grommet, a curable sealant according to EP 0 880 210 A1 is inserted into the gaps between the conductors or the groups of conductors of a cable bundle. During this process, a spacer is mounted on the conductors which holds them so as to provide gaps between the conductors in the area of the spacer.

Presentation of the invention

It is an object of the invention to provide a waterproofing cable guide assembly by means of which the penetration of moisture advancing in the single conductor of a cable guide or between the individual conductors of a cable guide into a moisture-tight space can be reliably prevented. Further, it is an object of the present invention to provide an insert element for a moisture-proofing cable routing arrangement and a method for producing a moisture-proofing cable guide arrangement.

This object is achieved by a cable guide arrangement having the features of claim 16, an insert element having the features of claim 1 and by a method having the features of claim 17.

In the following, the description will mainly be directed to a foamable material. Instead, however, flowable or pourable materials can be used and the foaming process can be replaced accordingly by a casting process.

The invention is based on the idea that a separation of the conductors, including conductors of different types and cross-sectional shape, during the foaming or casting process, in which the waterproofing material, in particular a foaming, flowable and / or pourable material to the conductors and is introduced between the conductors, helping that the conductors as possible individually during foaming, ie the sealing process, lie. The waterproofing material can then completely surround each individual conductor during foaming or casting. This can avoid areas where the individual conductors are directly adjacent to each other during the sealing process, leaving no foaming material or teats between them

Sealing material could penetrate and thus the waterproofness could not be completely guaranteed in this area. This effect of the invention is achieved in that the foaming material (foaming material hereinafter) spreads from the inner region of the cable or cable bundle to its outer region and thereby spreads apart the individual conductors to a limited extent so that foaming material around each Single conductor is provided in the foaming area. So that the conductors do not spread uncontrollably in this sealing process, d. H. move apart, the insertion element comprising the conductor is provided, in which at least one foam guide channel (guide channel) is provided, which brings the sealing material into the interior of the wire bundle. At the same time, the uncontrolled spreading of the individual conductors is prevented by the insert element, which comprises the cable harness to be sealed. Thus, in contrast to conventional methods in which the foaming material is externally applied to a wire bundle and in which the wires are compressed by spreading the foaming material from outside to inside, in the present invention, the sealing or foaming material comes from the core of the wire bundle introduced, whereby the individual conductors are pressed from the inside out.

The insert element, which is made for example as an injection molded part, is inexpensive to manufacture and can be attached to the cable harness, wiring harness or connector at the time of creating, so that no significant additional expense arises by providing the insert element on a wiring harness.

In addition to the targeted entry of sealing material, preferably foaming material, from the inside to the outside, the insert element simultaneously contributes to build up a targeted back pressure, which in turn contributes to the uniform foaming of the individual conductors. In addition, it is ensured that no single conductor comes to rest in the outer region of the finished assembly, since all individual conductors are guided through the interior of the insert element and then the material entry takes place so that the insert element itself is also surrounded by foam material or sealing material and thus in the finished moisture-sealing cable guide arrangement is not visible, but is embedded in sealing material.

Thus, a moisture-sealing wiring arrangement is provided, which not only in the radial direction of the line or

Cable bundle, but also in the longitudinal direction of water and moisture sealing.

In the following, the term longitudinal axis or longitudinal direction is always understood to mean that direction in which the individual conductors of the cable strand run. In contrast, the direction that is perpendicular to this longitudinal direction or that runs perpendicular to the longitudinal axis of the insert element is designated by the cross-sectional direction, wherein the longitudinal axis of the insert element substantially coincides with the longitudinal direction of the cable bundle.

Advantageous embodiments are characterized by the remaining claims.

The insert element used to make the moisture-proofing cable guide arrangement preferably has a plurality of outlet openings for sealing material, in particular foaming material, in its walls. This has the advantage that the sealing material, which is introduced through the inlet opening and the foam guide channel into the interior of the insert element and thus of the cable strand, basically only propagates from the inside to the outside, and finally to include the insert element and an almost any outer contour of the provided longitudinally watertight sealing element in the finished state. By the main propagation direction of the sealing material in the radial direction from the inside to the outside, and also to include the insert element outside, the propagation direction of the material is further supported from inside to outside, which causes the individual conductors of the cable harness are isolated even more reliable than, for example, in an alternative Embodiment in which the outer foam of the insert element is made from the outside.

According to a preferred embodiment, the insert element is designed substantially cylindrical or prismatic. In this case, the cylinder may have a circular cross section, a polygonal cross section or an oval cross section or the like. The cylindrical shape has the advantage that it can be produced simply and inexpensively, for example by injection molding, and substantially corresponds to the shape of a bundle of cables, so that as uniform a foaming as possible around the individual conductors by the uniform spreading of the foam is achieved during the foaming of the bundle of cables.

Advantageously, the inlet opening for the foaming material is provided on the cylinder wall in such a way that the inlet opening and the inlet openings are arranged symmetrically with respect to a le. * Imaginary plane of symmetry, which is perpendicular to the cylinder longitudinal axis, ie to the longitudinal axis of the insert element. This ensures that even in the longitudinal direction, the sealing material is evenly distributed, since it is centered with respect to the longitudinal direction or evenly introduced with respect to the center of the longitudinal axis. From the inlet opening or the inlet openings, the guide channel or the guide channels advantageously extends substantially perpendicular to the cylinder wall into the interior of the cable harness or cable bundle. This ensures that the foaming material travels a short distance before it can spread inside the insert element and possibly expand and can arrange around the individual conductors. The guide channel in turn is in turn preferably provided as a cylindrical body which is hollow in the interior and therein carries the foam or other sealing material.

According to a preferred embodiment, the insert element is designed in several parts, in particular preferably in two parts, wherein the parts along a separation surface which extends in the longitudinal direction of the insert element, can be reassembled into a complete, preferably cylindrical, insert element. For this purpose, the parts are connected, for example, along the separating surface with a film hinge and / or they are connectable with a latching or each separating surface a plurality of latching. The multipart design of the insert element ensures easy installation of the insert element on the cable harness or wiring harness, since the cable strand does not have to be threaded individually in the longitudinal direction through the insert element, but instead can be inserted. The formation of the multipart insert element with detents or a film hinge ensures that the assembly of the insert element in the cylindrical or otherwise suitably shaped body can be performed quickly and easily.

If locking or other locking devices are provided in order to connect the parts of the insert element with each other, then these are preferably formed in multiple stages, d. H. in particular with a first stage, in which the insert element encloses a larger cross section, and a second stage, in which the insert element encloses a smaller cross sectional area. This offers the possibility of initially holding the insert element in the first latching step when introducing the sealing or foaming material, while the latching into the second step preferably takes place immediately after filling of the foaming mold, so that compression of the foam within the insert element may last, possibly existing cavities can also be filled with foam.

According to a particularly preferred embodiment, branching devices are provided in the interior of the insert element, which are designed, for example, as pins or webs projecting from the inner walls of the insert element. These branching devices are preferably arranged irregularly in the insert element. If such branching devices are provided, then the individual conductors of the wiring harness can be guided individually around the branching, which further contributes to avoiding direct contact with one another during the sealing or foaming process, which in turn leads to worsened foaming and thus to deterioration worsened watertightness would result. Alternatively, such ramifications can also be effected, for example, by irregularly corrugating the individual conductors before they are introduced into the insert element.

Advantageously, the insert element is designed so that it tapers at its respective ends in the longitudinal direction and by means of the taper, which is preferably spread apart, d. H. elastic, is designed to hold the individual strands of the cable bundle stationary. This avoids unwanted slippage of the wire harness when the insert member is attached thereto. This helps to maintain mounting accuracy that is required to provide the moisture-sealed cable routing at a particular location, for example in the motor vehicle.

According to a particularly preferred embodiment, the insert element comprises a filling element comprising e.g. at least partially funnel-shaped foam supply channel or supply channel for sealing material, which is connectable to the inlet opening, when the filling element is clipped onto the preferably cylindrical body of the insert member or otherwise secured thereto. This simplifies the injection molding process of the insert element, in particular the removal of the finished insert element from the mold, wherein at the same time a funnel-shaped foam supply channel can be formed, which contributes to a good foam supply to the inlet opening. Preferably, the filling element is additionally connected to the walls of the inserting element, i. H. Preferably, the cylindrical body, latched to move i • • • * * # • »• Ml • λ. • Avoid 7 «during the foam application process. Alternatively, it is also possible to connect it, for example, only by means of the foam supply channel, which is designed as a tubular projection in the direction of the cylindrical body of the insert element, with the inlet opening of the insert element. If such a filling element is provided, then it is possible to adapt the connection geometry to the respective metering or foaming machine without having to change the insert element as a whole by merely adapting the filling element accordingly. Further, for example, a branching of the foam introduction channel may be provided as needed when the insert member has a plurality of foam guide channels.

The sealing or foaming material which is used for filling and foaming the insert element, as well as the finished outer contour of the cable guide arrangement can be adapted to the respective needs. In particular, the assembly can be produced in various outdoor hardnesses, where, for example, when a relatively high external hardness is required, for example, a foaming process can be performed to produce multiple layers, in which a harder outer layer is applied before or after the formation of another inner layer , The hardness is adjustable by suitable choice of the sealing or foaming material. At the same time, the combination of the sealing material and the embedded insert element provides a good sound damping function in the component, which is achieved in particular by the closed outer skin of the foaming material. Overall, the cable guide arrangement remains relatively easy, which mainly contributes to the low weight of the foam body.

Ways to carry out the invention

FIG. 1 shows an insert element 10 according to the invention. The insert element 10 is substantially designed as a circular-cylindrical body which tapers at its two ends in the longitudinal direction. The entire cylindrical insert element 10 is hollow, so that a cable harness with a plurality of lines, which may also have different line cross-sections, can be inserted into the interior of the insert element 10.

The insertion element 10 shown in Figure 1 comprises two halves 11, 12, and a filling element 13. In Figure 2, the corresponding parts of the insert member 10 are shown in exploded side view.

The insert element 10 shown in Figures 1 and 2 can be placed around a harness by the open state, which is shown in Figure 2, a harness is inserted into one half of the insert element, for example, in the half 11 of the insert element, after which the half 12th by means of Verrasteinrichtungen 14, which are shown as positive connections in Figure 2, with the half 11 is connected. The insert element 10 shown in FIGS. 1 and 2 has two halves 11, 12 which respectively enclose a cable bundle approximately in a 180 ° region. It is also possible to make one of the halves 11 or 12 significantly larger than the other, d. H. to cover a larger angle range. Instead of the locking means 14, which can latch with projections 15 on the lower half 12 of the insert member, it is possible to connect the halves 11, 12 along a parting surface with a likewise formed in the injection molding process with a correspondingly thin wall thickness film hinge and only along a second parting surface To lock the halves of the insert element after inserting the individual conductors of the cable bundle with each other.

The tapered portions 16, 17 of the insert member, which serve to hold the insert member fixed on a wire harness are also integrally molded with the cylindrical body 11, 12 of the insert member and are resiliently formed by individual sections provided therebetween slots in the circumferential direction are separated from each other. As a result, both a cable strand with a thicker width and one with a thinner width in the insert element 10 are inserted and by the tapered portions, which spread to a limited extent adapted to the thickness of the harness, position and are kept stationary. .10 :. 4 • * • * t »\

In the embodiment shown in Figures 1 and 2, the insert element 10 is substantially cylindrical and designed with a circular cross-section. In principle, it is also possible to provide a polygonal cross-section, an oval cross-section or the like, which can also be adapted as required to the shape of the cable harness to be performed.

Each of the halves 11, 12 of the insert element 10 shown in Figures 1 and 2 is provided with outlet openings 18 for the foaming material. Through these outlet openings, which can be placed as needed around the circumference and in the longitudinal direction of the insert element, foaming material, which is introduced into the interior of the insert element, emerge and then also foam the insert element itself.

In order to introduce the foaming material, one half 11 of the insert element 10 in the embodiment illustrated in FIGS. 1 and 2 has an inlet opening (not visible) to which a tubular foam guide channel 20 adjoins, which is substantially perpendicular to the longitudinal axis of the insert element 10, ie. H. extends in the radial direction of the insert element. The foam guide channel 20 terminates approximately in the middle of the cross section of the insert element and is further arranged so that it is also centrally positioned in the longitudinal direction of the insert element 10. In the non-visible inlet opening for the foaming material, an extension 21 of the foam supply channel 22 can be used, which is provided in a filling element 13. The filling element 13 in turn has locking means 19 with which it can be locked on the outside cylindrical surface of a part of the insertion element 11. The filling element 13 preferably has a funnel-shaped foam supply channel 22, which is suitable for connection to an injection molding machine or foaming machine.

If, in an alternative embodiment, a plurality of guide channels 20 for sealing material, here foaming material, are provided in the insert element, the filling element 13 can additionally have a branching of the foam supply channel 22. Furthermore, with the aid of the filling element 13, it is easily possible to provide a suitable connection for each injection molding or foaming machine by merely varying the connection geometry of the filling element 13.

The insert element 10 may additionally have positioning aids, with which it is easy to position in the form of a foaming tool or an injection molding tool. For example, this is • · «* • · Ä. Can be seen in Figure 5, in which a mold half 11 is shown in a state inserted into a foaming tool, wherein the half 11 of the insert element by the positioning aid 23, as from the outside of the cylinder wall projecting pin is designed, is held in a fixed position in the corresponding recesses of the mold half of the foaming tool 30.

It can also be seen from FIGS. 2 and 5 that the insert element 10 preferably additionally has pin-like or web-like projections in its interior, which serve as branching devices for the individual lines of the cable strand. These projections 24 are preferably arranged irregularly in the interior of the insert element and can equally be provided in the part 11 and in the part 12 of the insert element. The individual conductors of the cable harness can be guided around them as needed, so that individual conductors do not come to lie next to each other as possible.

For the sake of completeness, it should be noted that the arrangement of the part of the insert element 10 shown in FIG. 5 shows an arrangement which has two contacting channels which respectively lead into the interior of the insert element and thus the interior of the cable strand as close as possible to its center.

The production of a cable guide arrangement with moisture-sealing properties using an insert element 10 will be described below with reference to FIGS.

First, an insert element 10 is attached to a cable harness of a wiring harness such that the individual conductors of the cable strand are placed around the branching devices 24 in the interior of the insert element 10, so that they are as single as possible, d. H. do not collide. In this case, the insert element 10 is opened when such opening of the insert element is possible. Alternatively, it is of course also possible, albeit more complex, to guide the individual cables in the longitudinal direction through the insert element, if this can not be opened. Subsequently, the insert element 10 is assembled by the parts 11, 12 are closed against each other. For this purpose, the locking means 14, 15 are locked in a first position, d. H. taking advantage of first locking lugs 15, so that the insert element is assembled into its substantially cylindrical shape.

Alternatively, it is also possible, first a part 11 of the insert element, optionally with attached filling element 13, in a • ····· ·· * * ·· ί-2ί ·.

Insert mold half 30 of a foaming tool, then introduce the harness with the individual lines in this half of the insert member 11 and finally connect the second half of the insert member 12 with the first half 11 and lock. However, it is preferred to install the insert element 10 already when assembling the wiring harness on the corresponding cable harness. This saves additional manufacturing effort during the foaming process.

Subsequently, the filling element 13 is placed on the cylindrical body of the insert element and possibly latched or clipped thereto.

The entire assembly is now placed in a foaming tool 30 in such a way that the inlet opening for foaming material 22 is aligned with a foam feed channel 31 of the mold 30. At the same time, the insertion element 10 is positioned by means of the positioning projections 23 in corresponding recesses of the molding tool 30. The conductors which are inserted into the insert element are guided through inlets and outlets for the cable bundles 32, 33. The foaming tool can, depending on the desired outer geometry, d. H. In particular, the predetermined outer shape, which is necessary for fastening the waterproofing cable guide arrangement on a wall of, for example, a vehicle, be provided with corresponding shapes 35. For example, projections and grooves may be provided on the outer geometry of the finished longitudinal water seal. In the embodiment shown in FIG. 5, the finished longitudinal water seal should essentially be in the shape of a cartridge and additionally have projections or depressions extending in the circumferential direction, as can be seen, for example, in FIG.

After the insert element is positioned with the cable strand inserted therein in the mold 30, the mold is closed and foaming material is guided via the foam supply channel 31 of the mold, the inlet opening 22 in the filling element and the foam guide channel 20 and the feed channels 20 into the interior of the insert element it at the same time in the central area, d. H. the central region, the wire harness seen in the radial direction. For example, hotmelt, coldmelt, macromelt, butyl and other foam materials can be used as foaming materials with good sealing properties for sealing the cable strands. For example, PU or silicone foams and encapsulants can be used. Alternatively and preferably, polyurethane foam can also be used. The introduced into the central region of the insert element and the cable strand expands and initially spreads in the interior of the insert element and thereby encloses the individual conductors of the cable harness, which are well isolated in the interior of the insert element. This effect is supported by the fact that the individual conductors are held bundled by the cone-shaped end portions 16, 17 of the insert element, but on the other hand pressed by the pressure, which applies the foaming material from the inside to the outside and thus fanned so far that foaming material to can distribute all individual conductors. When the foaming material has reached the wall of the insert element 10, it exits through the foaming material outlet openings 18 provided in the wall of the insert element 10 and additionally encloses the insert element 10 and the conductors emerging therefrom in the region in which the Foaming material is introduced, d. H. between the inputs and outputs 32, 33 for the cable harness. It fills out the mold 30, 31 of the foaming tool. In this case, the foaming material expands so far that it rests against the wall of the mold 30, 31 and assumes the predetermined shape thereby.

As long as the foaming material is not solidified in the interior of the insert element or the exterior of the insert element is not yet enclosed with foaming material, the insert element can be reduced in its inner cross section as required by the locking of the upper and lower Einlegeelementteils 11, 12 are moved, d , H. the latch is set to a second stage, wherein the inner cross section of the insert element is reduced. As a result, the foaming material is further compressed and any remaining hollows are filled with foam.

After the foaming process, the foam or the casting compound, for example polyurethane or silicone, reacts, after which the finished arrangement can be removed from the mold.

The arrangement thus provides a watertight embodiment of a watertight cable leadthrough both in the radial direction of the cable strand and in the longitudinal direction of the cable strand.

A finished cable guide assembly 40 is shown in Figures 3 and 4 in cross-section and in side view. As can be seen in FIG. 4, in the illustrated embodiment, the entire sealing arrangement is essentially in the shape of a cartridge with circumferential grooves running in the circumferential direction, which can be mounted on a passage opening in a passage opening in one

Serve vehicle wall. The individual conductors of the cable strand 42 emerge at the two ends in the longitudinal direction of the cartridge-shaped arrangement 41. Of course, conductors of different thickness can be integrated into a cable harness, as can be seen for example from FIG. It is also clear from FIG. 3 that both the interior of the insert element 11, 12, 13 is completely filled with foam material 44 and the entire outer area around the insert element 11, 12, 13 is surrounded by foaming material which finally determines the final outer shape ,

The essential aspect of the invention is thus to provide a very good waterproofing cable guide arrangement, in particular, a tightness in the longitudinal direction of the cable harness is guaranteed and still occur in the no significant additional costs compared to conventionally foamed cable routing arrangements. This is accomplished by providing an inlay element 10 which allows for foam entry which propagates outwardly from the center of the inlay element and thus the harness. This effect can be supported by the fact that the individual conductors of the cable harness are held in a fixed position in the interior of the insert element by appropriate branching devices.
