Description

Technical Field

[0001] This invention relates to a partition channel for at least one cable and / or conduit intended to pass through a partition, particularly for applications in the automotive, aerospace, or rail sectors. The invention also relates to a method for installing at least one cable and / or conduit into the partition channel. Background Technology

[0002] In many fields, such as automotive, aerospace, or rail, it is common to use cable-connected electronic equipment and / or piping for fluids to ensure the control of different components of a vehicle or equipment. These applications typically require passage through a partition structure, and therefore through at least one partition, particularly through openings within that partition. This passage must be, for example, sealed, both waterproof and preventing the flow of particles (contaminants or dust), and soundproof to prevent noise from spreading from one compartment to another, thus avoiding disturbance.

[0003] There are typically different types of partition channels.

[0004] The first type provides a partition channel made of a flexible and stretchable material, allowing cables and / or pipes of different sizes to pass through. However, the disadvantage of this type of partition channel is that it is difficult to install and easy to detach from the structure on which it is installed, while it is desirable for the partition channel to remain within the partition to keep the cables and / or pipes in place.

[0005] The second type provides a partition channel comprising a support member made of flexible material and a rigid counter-support member, which are assembled together, for example, nested together. This type of partition channel has the advantage of being expandable to pass through cables and / or pipes, and requires low installation force but high disassembly force. In other words, this type of partition channel is easy to install into a partition but difficult to remove. However, during the passage of various cables and / or pipes through the partition channel, this assembly method limits its expansion capability due to the rigid counter-support member restricting the expansion space. Therefore, the size of cable connectors may be larger than the size allowed to pass through by the rigid counter-support member, and thus cannot pass through the partition channel. In addition, this type of partition channel also carries the risk of separation between the support member and the counter-support member during use, leading to the aforementioned performance degradation.

[0006] Therefore, the object of the present invention is to provide an improved partition channel, in particular allowing the extension of a rigid anti-support to allow at least one large-sized element to pass through without the risk of damaging the element or the partition channel. Summary of the Invention

[0007] Therefore, a partition channel for at least one cable and / or conduit is proposed, comprising:

[0008] - An elastomer-based support member, comprising a plate having a through-hole for at least one cable and / or conduit; and

[0009] - A counter-support, which is more rigid than the support, is in the form of at least two parts. The counter-support extends from the plate of the support in a direction generally perpendicular to the plate and is arranged around the through hole. Each part has at least one side end, which is connected to the side end of the other part closest to the counter-support by a tongue belonging to the support.

[0010] Therefore, thanks to the partition channel according to the invention, improved separation between the different parts of the counter-support is ensured during use. In fact, one or more tongues connecting the side end of one part of the counter-support to another part can deform with the stretching of the support, thus causing displacement of at least one part of the counter-support relative to the other part. In this way, the passage area defined by the counter-support, which is stiffer than the support, can be expanded to allow elements with dimensions significantly larger than those of the counter-support in its initial, i.e., non-sollicité state, to pass through.

[0011] The partition channels according to the invention may include one or more of the following features, either independently or in combination with each other:

[0012] - At least two parts of the anti-support are separated from each other, each of the separated parts thus having two side ends, each of the two side ends being connected by a tongue to the side end of the other part closest to the anti-support;

[0013] - The anti-support is in single-piece form;

[0014] - The counter-support includes at least two clamping members extending from the radial outer wall of the counter-support, the clamping members being received in an opening arranged in the radial outer wall;

[0015] - Each separate portion of the anti-support includes at least one clamping member extending from the radial outer wall of the portion, the clamping member being received in an opening arranged in the radial outer wall;

[0016] - Membrane filling openings belonging to the support components;

[0017] - The support component based on the elastomer is made of an elastomer, thermoplastic elastomer material or thermoplastic vulcanized elastomer material;

[0018] - The anti-support component is made of thermoplastic material or thermoplastic vulcanized elastomer material;

[0019] - The plate of the support member has at least one circumferential lip for abutting against the surface of the partition outside the partition channel;

[0020] - The counter-support is located between the plate of the support and the truncated conical skirt belonging to the support in a direction generally perpendicular to the plate. The truncated conical skirt extends around the through hole and includes a second lip at its free end for abutting against the surface of the partition outside the partition channel.

[0021] - The anti-support member is located between the plate of the support member and the semi-cylindrical protrusion in a direction generally perpendicular to the plate member, the protrusion extending around the longitudinal axis and belonging to the support member;

[0022] - The support includes at least one neck configured to secure at least one cable and / or pipe;

[0023] - The neck extends protruding from the sheet in a direction generally perpendicular to the sheet;

[0024] - The support and the counter-support are connected to each other by chemical bonding.

[0025] The present invention also relates to a method for installing at least one cable and / or conduit in a partition channel as described above, the method comprising the following steps:

[0026] -Stretch the elastomer-based support member to separate the anti-support members from each other.

[0027] - Insert at least one cable and / or pipe through the through hole of the support.

[0028] - Fold the elastomer-based support member onto the cable and / or conduit, then

[0029] - Install a partition channel carrying at least one cable and / or conduit into the opening of the partition for this purpose.

[0030] The method according to the invention may include one or more of the following features, either independently or in combination:

[0031] - After the closure support is closed, but before the partition channel is installed into the partition, tape is wrapped around the cable and / or pipe and at least a portion of the elastomer-based support, with the cable and / or pipe and at least a portion of the support together wrapped in tape.

[0050] In these figures, the same reference numerals correspond to the same or similar elements. Detailed Implementation

[0051] Hereinafter, an example of a partition passage 10 according to the invention for passing through a partition S that separates two compartments of a structure is discussed. For example, partition S can separate the driver's cab and the engine compartment in a motor vehicle.

[0052] It should also be understood that the partition channel 10 according to the invention is designed to allow one or more cables to pass through, which may be aggregated into one or more cable bundles. It is understood that a cable bundle is formed by aggregating multiple cables. It should also be understood that the cable or cable bundle includes a cable or cable bundle with one or more associated connectors. A connector is a device for connecting one or more cables to a device.

[0053] It should also be understood that cables can be substituted for conduits, and therefore the partition channel 10 is also designed to allow one or more conduits to pass through. It should also be understood that the partition channel 10 is designed to allow at least one cable and / or at least one conduit to pass through.

[0054] In the following text, the partition channel 10 for at least one cable and / or conduit will be described in a non-limiting manner. Figures 1 to 17 Various embodiments of the partition channel 10 according to the invention are shown. The partition channel 10 according to the invention includes an elastomer-based support 12 and an anti-support 14 having a stiffer structure than the support 12.

[0055] The support member 12 includes a plate 16 having a through hole 18 for at least one cable and / or conduit. It should be understood that the through hole 18 extends in the plane of the plate 16. Preferably, the through hole 18 is located at the geometric center of the plate 16.

[0056] The support 12 is based on an elastomer, which may be made of a material not limited to those selected from: ethylene propylene monomer (EPDM), styrene-butadiene (SBR), butadiene-acrylonitrile (NBR), isobutylene-isoprene (IIR), or natural rubber (NR), thermoplastic elastomer (TPE) or thermoplastic vulcanizate (TPV), such as polypropylene / ethylene-propylene-diene monomer (PP / EPDM) or polyamide / ethylene-propylene-diene monomer (PP / EPDM). The support is made of polypropylene / styrene-ethylene / butylene-styrene (PP / SEBS) or polypropylene / styrene-butadiene-styrene. It is understood that the support possesses a certain degree of flexibility and adaptability. In this way, the support 12 can deform and return to its initial shape after a force is applied to it.

[0057] Advantageously, the plate 16 of the support member 12 includes at least one circumferential lip 32. This circumferential lip 32 is also designed to abut against the surfaces S1, S2 of the partition S outside the partition channel 10, for example... Figure 8 As shown. In use, the circumferential lip 32 is configured to ensure a seal around the hole formed in the partition S for mounting the partition channel 10. For example, the lip 32 abutting against the surface S1 also makes it possible to maintain uniform contact pressure on the clamping member 26 (described below).

[0058] The support member 12 may also include at least one neck 34, 34', 36 for securing cables and / or conduits. (See reference...) Figures 1 to 5 The necks 34 and 34' can extend from the plate 16, particularly at the extension of the through hole 18. (See reference...) Figure 1 , 5 10 and 11, each neck 34 may extend in a direction X generally perpendicular to plate 16. (See reference...) Figure 10The neck 34 may face one side of the plate 16 from which the counter-support 14 extends, as described below. Alternatively, the neck 34 may also face the side of the plate 16 opposite to the side from which the counter-support 14 extends, as described below. Figure 1 and Figure 5 As shown. Advantageously, the neck 34 is configured to flip, i.e., the neck 34 can be rotated from... Figure 1 The state becomes Figure 10 The state is the same, and vice versa. In other words, the neck 34 can face one side or the other side of the plate 16. In a variation, the neck 34' can have the following characteristics: Figure 3 and Figure 4 As shown and as Figure 2 The elbow shown in the middle section.

[0059] The counter-support 14 is stiffer than the elastomer-based support 12. The counter-support 14 extends from the plate 16 of the support 12 in a direction X generally perpendicular to the plate 16. The counter-support 14 is also arranged around the through-hole 18. The counter-support 14 has at least two portions 14', 14”, 14a-14d extending from the plate 16 in the direction X. Each portion 14', 14”, 14a-14d also has at least one side end 15, 15a, 15a', 15b, 15b', 15c, 15c', 15d, 15d'. The side ends 15, 15a, 15a', 15b, 15b', 15c, 15c', 15d, 15d' are connected via tongues 20, 20' belonging to the support member 12 to the side ends 15, 15a, 15a', 15b, 15b', 15c, 15c', 15d, 15d' of the other part 14', 14”, 14a-14d closest to the anti-support member 14.

[0060] Reference Figures 1 to 3 and Figure 16 The counter-support 14 can be a single piece. Therefore, it should be understood that this single piece means that part 14' and part 14" are integral. Furthermore, the two parts 14', 14" are arranged opposite each other. In these examples, each part 14', 14" includes a side end 15 facing the other part 14', 14" . In other words, the counter-support 14 has two side ends 15 facing each other; the side end 15 of part 14' is the end closest to the side end 15 of part 14" . These two side ends 15 are connected to each other by a tongue 20 belonging to the support 12.

[0061] refer to Figure 4 , Figure 5 as well as Figures 10 to 13The counter-support 14 may also take the form of at least two distinct portions 14a-14d. These distinct portions 14a-14d extend from the plate 16 of the support 12 in the direction X and are arranged integrally around the through hole 18. Thus, each distinct portion 14a-14d has two side ends 15a-15d, 15a'-15d'. It should be understood that each portion 14a-14d has two side ends 15a-15d, 15a'-15d' because these portions 14a-14d are distinct from each other. It should also be understood that the side ends 15a-15d, 15a'-15d' may extend in the direction X. In addition, one side end 15a-15d, 15a'-15d' of each part 14a-14d of the support member 14 is connected to the other side end 15a-15d, 15a'-15d' of the other part 14a-14d closest to the support member 14 via tongues 20, 20' belonging to the support member 12.

[0062] For example, Figure 4 , Figure 5 , Figure 12 and Figure 17 The counter-support 14 in this embodiment includes two distinct portions 14a and 14b. In this case, the tongue 20 connects the side end 15a of the first portion 14a of the counter-support 14 to the side end 15b' of the second portion 14b of the counter-support 14, which is closest to the side end 15a. Similarly, the tongue 20' connects the side end 15a' of the first portion 14a of the counter-support 14 to the side end 15b of the second portion 14b of the counter-support 14, which is closest to the side end 15a'.

[0063] exist Figure 10 and Figure 11 In other embodiments shown, the counter-support 14 comprises four distinct portions 14a-14d. In this case, a first tongue 20' connects the side end 15a of the first portion 14a of the counter-support 14 to the side end 15b' of the second portion 14b of the counter-support 14. A second tongue 20 connects the side end 15b of the second portion 14b to the side end 15c' of the third portion 14c. A third tongue 20' connects the side end 15c of the third portion 14c to the side end 15d' of the fourth portion 14d. Furthermore, a fourth connecting piece 20 connects the side end 15d of the fourth portion 14d to the side end 15a' of the first portion 14a of the counter-support 14.

[0064] The anti-support 14 can be made of a thermoplastic material, including but not limited to polypropylene (PP), polyamide (PA), or polyoxyméthylene (POM), or a vulcanized thermoplastic material. The thermoplastic or vulcanized thermoplastic material can be highly filled, such as glass fiber, carbon fiber, chalk, or talc. The filler content of glass fiber, carbon fiber, chalk, or talc can be up to 40%. The selection of the aforementioned different materials should make them more rigid than the material of the support 12.

[0065] The hardness of the counter-support 14 is studied to ensure that the element 10 passing through the partition channel is mechanically protected from the effects of the partition interface. Furthermore, this hardness facilitates the installation and fixation of the partition channel 10 within the holes in the partition provided for this purpose.

[0066] The counter-support 14, and therefore each portion 14a-14d, is located on the axially extending portion of the support 12, and may have, as Figures 1 to 5 and Figure 10 The free end is shown.

[0067] Advantageously, the counter-support 14 is overmolded onto the support 12, for example, by adhesive bonding, or the support 12 and the counter-support 14 are manufactured using a dual-injection process. This provides a better connection between the support 12 and the counter-support 14, improving the seal between the two components. It should be understood that the partition channel 10 is of dual material, i.e., the integral partition channel 10 comprises at least two materials with different properties. In other words, the support 12 and the counter-support 14 of the partition channel 10 are chemically bonded together. The same applies to the side ends 15a-15d, 15a'-15d' of the different portions 14a-14d of the tongue 20 and the counter-support 14.

[0068] To improve the connection between the support member 12 and the counter-support member 14, the materials of the support member 12 and the counter-support member 14 can be selected to have similar thermoplastic substrates. For example, the selected pair of materials can be PP / TPV (PP / EPDM), PA / TPV (PA / EPDM), or PP / TPE (PP / EPDM).

[0069] Alternatively, additional adhesive can be used to connect the support 12 and the counter-support 14.

[0070] Figure 6 and Figure 7 This is shown very schematically in the case where the anti-support 14 is a single piece (by... Figures 1 to 3 (Example shown) Stretching of the partition channel 10. This stretching of the partition channel 10 causes deformation of the tongue 20 belonging to the support 12, which connects the two parts 14', 14' of the anti-support 14.

[0071] Figure 6 The partition channel 10 is shown in its initial state (i.e., when the partition channel 10 is not under stress). In this example, the partition channel 10 includes a tongue 20 that connects the side ends 15 of each portion 14', 14" to each other. In this initial state, the dimension d of the tongue 20 is equal to the distance between the respective side ends 15 of the two portions 14', 14" of the counter-support 14.

[0072] Figure 7 The partition channel 10 is shown in a stressed state (i.e., when the support 12 is stretched to allow at least one cable and / or conduit to pass through the through-hole 18), the through-hole 18 itself being stretched by expanders E. The expanders E inserted into the through-hole 18 are moved away from each other, stretching the support 12 and causing portions 14', 14" to separate, while the tongue 20 deforms to present a dimension d' larger than the dimension d determined in the initial state. This reflects the stretching of the tongue 20. The separation of portions 14', 14" allows for an expansion of the passage area without being limited by the dimensions of the counter-support 14.

[0073] In this case, the relative elasticity of the counter-support 14 with respect to the portion of the hole 18 opposite to the tongue 20 limits possible separation. In fact, the counter-support 14 is made of a material with a given hardness, and the stress applied to it should not damage the counter-support 14.

[0074] Figure 8 and Figure 9 This is shown very schematically in the case where the anti-support 14 is in the form of two different parts 14a, 14b (by... Figure 4 , Figure 5 and Figure 12 (Example shown) Stretching of the partition channel 10. This stretching of the partition channel 10 causes deformation of at least one tongue 20 belonging to the support 12, which connects two different parts 14a, 14b of the anti-support 14.

[0075] Figure 8 The partition channel 10 is shown in its initial state (i.e., when the partition channel 10 is not under stress). In this example, the partition channel 10 includes a first tongue 20' that connects the side end 15a of the first portion 14a of the counter-support 14 to the side end 15b' of the second portion 14b of the counter-support 14. Similarly, the second tongue 20' connects the side end 15a' of the first portion 14a of the counter-support 14 to the side end 15b of the second portion 14b of the counter-support 14. In this initial state, the dimension d of the tongue 20 is equal to the distance between the side ends 15a of the first portion 14a and the side ends 15b' of the second portion 14b of the counter-support 14.

[0076] Figure 9 The partition channel 10 is shown in a stressed state (i.e., the through-hole 18 itself is stretched when the support 12 is stretched to allow at least one cable and / or conduit to pass through). In this state, due to the stretching of the support 12, the first portion 14a and the second portion 14b separate from each other, and the tongue 20 deforms to present a dimension d' that is larger than the dimension d determined in the initial state. This reflects the stretching of the tongue 20. The separation of the first portion 14a and the second portion 14b allows for an expansion of the passage area without being limited by the size of the counter-support 14.

[0077] In the above situation, the second tongue 20' is deformable like the first tongue 20, and is preferably located opposite the first tongue with respect to the hole 18. This eliminates the previous... Figure 6 and Figure 7 The limitations mentioned in the example.

[0078] In these examples, each tongue 20, 20' is connected to the side ends 15 of portions 14', 14" starting from plate 16, or to the side ends 15a, 15a', 15b, 15b' of portions 14a, 14b, thus ensuring a seal between them; that is, a seal between portions 14', 14" or a seal between the separate portions 14a, 14b of the counter-support 14. For Figures 10 to 17 Other embodiments shown also verify this characteristic.

[0079] As a variant Figure 5 The annular strip 38 shown can extend around the counter-support 14. This strip 38 also connects each tongue 20. Therefore, it should be understood that this strip 38 also belongs to the support 12 and is thus made of the same material as the support 12. This annular strip 38 increases the contact surface between the elastomer-based support 12 and the counter-support 14, thereby facilitating their connection.

[0080] The counter-support 14 may include at least two clamping members 26 extending from the radially outer wall 28 of the counter-support 14. Preferably, one clamping member 26 is symmetrically positioned with respect to the other clamping member 26 about the through hole 18. In particular, each different portion 14a-14d of the counter-support 14 may include at least one clamping member 26. In some embodiments, for example Figure 4 , Figure 5 or Figures 12 to 13 In the illustrated embodiment, one or each part 14a-14d may include two clamping members 26.

[0081] The clamping member 26 can be accommodated in the opening 29, which is arranged in the radial outer wall 28. The opening 29 allows slight radial movement of the clamping member 26 when the partition channel 10 is installed. This movement may manifest, for example, as bending of the clamping member 26.

[0082] In some cases, the counter-support 14, particularly the clamping member 26, may be exposed to environmental stress, fluid sources, dust sources, heat / cold sources, or noise sources. Furthermore, to prevent fluids, dust, etc., from passing through the opening 29, the membrane 30 belonging to the support 12 advantageously fills the opening 29 provided in the radial outer wall 28, such as... Figures 12 to 17 As shown. Therefore, the membrane 30 ensures a seal between the exterior of the partition channel 10 and the internal passageway through which cables and / or pipes pass. The membrane 30 is part of the elastomer-based support 12 and is deformable to allow slight radial displacement of the clamping member 26 when the partition channel 10 is installed in the partition S.

[0083] exist Figure 11 In the example shown, the anti-support 14 is positioned along direction X between the plate 16 of the elastomer-based support 12 and the frustoconical skirt 13 belonging to the support 12. The skirt 13 may also extend around the through-hole 18. The skirt 13 includes a free end defining a lip 33. The lip 33 is also used to abut against the surfaces S1, S2 of the partition S outside the partition channel 10. The skirt 13 is also designed to flip when the partition channel 10 is installed, such that the lip 33 of the skirt 13 abuts against the surfaces S1, S2 of the partition S.

[0084] exist Figures 12 to 15 In the example shown, the counter-support 14 is positioned along direction X between the plate 16 of the support 12 and the semi-cylindrical protrusion 13' belonging to the support 12. The protrusion may also extend around the hole 18. The protrusion 13' may include a neck 36 for securing cables and / or conduits, extending from the free end of the protrusion 13'. Furthermore, the protrusion 13' may cover the positioning tolerances of the cables and / or conduits. That is, the position of the cables and / or conduits does not necessarily have to be perpendicular to the plate 16. There may be a certain range of deviation relative to this direction.

[0085] The present invention also relates to a method for installing at least one cable and / or conduit into a partition channel 10 as described above, the partition channel 10 being located in a partition S that separates two compartments of a structure (such as the driver's cab and engine compartment of a motor vehicle).

[0086] The installation method includes the following steps:

[0087] -Stretch support 12 to separate portions 14', 14”, 14a-14d of counter-support 14 from each other.

[0088] - Insert at least one cable and / or pipe through the through hole 18 of the support 12.

[0089] - Close the elastomer-based support 12, and then

[0090] - Install the partition channel 10 carrying cables and / or pipes into the opening of the partition S set for this purpose.

[0091] Reference Figures 6 to 9 The support member 12 can be stretched, for example, by means of expanders E. These expanders E are inserted into the hole 18 and then radially separated from each other. Thus, the hole 18 is enlarged, and the support member 12 is stretched. Therefore, when the elastomer-based support member 12 is stretched, portions 14', 14" and 14a-14d of the counter-support member 14 are separated from each other due to their connection to the support member 12 at the plate 16. In this stressed state, the passage area defined by the counter-support member 14 is larger than the passage area in the initial state, thereby allowing cables and / or conduits with dimensions larger than the passage area in the initial state to pass through. In the case of cables, these elements may be, for example, connectors.

[0092] Cables and / or conduits are inserted to pass through the passage area defined by the counter-support 14 under stress and through the through-hole 18 of the support 12, without a predetermined insertion direction. Then, with necks 34, 36 present, the cables and / or conduits are secured in place in the partition channel 10 via necks 34, 36.

[0093] Once the cable and / or conduit is inserted through the through-hole 18, the elastomer-based support 12 closes again onto the cable and / or conduit. It is understood that when the expander E is used, it is removed, allowing the through-hole 18 to substantially return to its initial size.

[0094] After the support member 12 is assembled onto the cable and / or conduit, tape may be wrapped around the cable and / or conduit, as well as at least a portion of the support member 12. It should be understood that the cable and / or conduit, and a portion of the support member, are wrapped together with the tape. For example, the tape may be adhesive tape. This step is preferably performed before the step of installing the partition channel 10 described below. This wrapping step prevents the cable and / or conduit from slipping and also ensures a seal between different cables and / or conduits.

[0095] The partition channel 10, which contains cables and / or pipes, is then installed in the opening of the partition S for this purpose. Preferably, the counter-support 14 is forcibly inserted into the opening of the partition S.

[0096] When the counter-support 14 includes clamping members 26, these clamping members 26, once passing through the opening, form an axial hold for the partition channel 10, making the partition channel difficult to remove by abutting against the surface S2 of the partition S. This hold can be improved by the circumferential lip 32 of the plate 16, which, when the plate 16 is present, abuts against the surface S1 of the partition S, such as... Figure 8 As shown. The lip 32 can also improve the sealing at surface S1.

[0097] When the support member 12 includes a truncated skirt 13 ( Figure 5 When the truncated conical skirt 13 flips as it passes through the opening in the partition S, the lip 33 at the free end of the skirt 13 abuts against the surface S2 of the partition S in addition to the clamping member 26. In this way, the fixation and sealing of the partition channel 10 can be improved at the surface S2.

[0098] As can be clearly seen from the foregoing description, the partition channel 10 according to the invention makes it possible to improve the separation between the different parts of the counter-support. In fact, one or more tongues connecting the side ends of one part of the counter-support to the side ends of another part can deform as the support is stretched, thus causing at least one part of the counter-support to displace relative to the other part. In this way, the passage area defined by the counter-support, which is stiffer than the support, can be expanded to allow elements with dimensions significantly larger than those of the counter-support in its initial state (i.e., stress-free state) to pass through.

[0099] Another advantage is that the sound insulation and fluid isolation performance is improved due to the connection between the side ends of the separate portions of each tongue and the anti-support, on the one hand, and on the other hand (when present) each clamping member abutting against each membrane.
