Description

[0001] The present invention relates to a cable entry device that can be mounted on a wall, e.g., of a control cabinet, at a through-hole through which electrical cables or signal cables or fluid hoses must be guided in an orderly and stable manner, so that a desired degree of tightness is ensured and the risk of undesired damage and movement of the cables themselves is avoided.

[0002] EP1236256 A1 discloses cable entry devices consisting of two frame parts that can be connected to each other in the closed position to form a rectangular frame and that can be separated from each other in the open configuration. The two frame parts define several passage seats for receiving one or more elastic cable entry devices that are applied around the cables or pipes, whereby

[0003] - when the two frame parts are in the open position, the cable glands can be positioned in the passage seats or removed from the passage seats together with the cables or ducts they enclose,

[0004] - when the two frame parts are in the closed position, the cable glands are in close contact with each other and with the frame parts and, together with the frame parts, form a substantially watertight plate through which the cables enclosed by the cable glands pass.

[0005] It is also known to obtain a first U-shaped or comb-shaped frame part with a base support from which two lateral posts protrude and, if appropriate, one or more further intermediate posts, wherein the passage seats are each delimited between two adjacent posts, so that a temporary insertion and positioning of the cable bushings is possible only in the first frame part.

[0006] It is also known to provide a second frame part in the form of a support which can be connected to the originally free ends of the side and central posts of the first frame part in order to close the passage seats and tighten the cable glands in the closed position.

[0007] It is also known to design the second U- or comb-shaped frame part, which is substantially a mirror image of the shape of the first frame part, so that it can be connected to the first frame part in order to close the passage seats and to tighten the cable glands in the closed position.

[0008] It is also known to provide the cable bushings with a grooved or ribbed outer surface and the through-seats of the frame parts with a grooved or ribbed inner surface in order to increase the local contact pressure and thus the sealing between the through-seats and the cable bushings when the cable bushing device is in the closed position.

[0009] The cable entry device is attached to the application wall by screwing it using fastening screws, e.g. four pieces, and by inserting a suitable seal between the cable entry device and the wall itself.

[0010] In order to enable the fastening screws to be screwed into the application wall (which is usually made of thin sheet metal or a material unsuitable for tightening the screws), it is known to attach corresponding bushings or rivets with internal thread to the application wall.

[0011] However, the state-of-the-art cable entry devices have several disadvantages.

[0012] The correct positioning of an additional seal (initially separated from the frame of the cable entry device) between the cable entry device and the wall is not practical.

[0013] Incorrect positioning of an additional seal and / or uneven or excessive tightening of the fixing screws may damage the additional seal and compromise the sealing of the installed cable entry device.

[0014] The plastic frame parts manufactured by casting have flatness tolerances which are added to the flatness tolerances of the application wall and are not always fully compensated by the elastic deformation of the seal additionally inserted between the cable entry and the application wall.

[0015] To date, the continuity of the sealing barrier between the interface areas between the cable penetrations and the passage seats, as well as the sealing areas between the different frame parts and the sealing areas between the frame parts and the wall, has not been guaranteed.

[0016] According to the prior art, the seal between the cable entry device and the wall is the same gray or black color as the frame parts. The lack of color contrast between the seals and the frame parts makes it difficult to separately observe the seal in relation to the frame parts, their correct mutual positioning, and any anomalies in shape, interruptions in continuity (damage, cuts, twisting), or position of the seals. This difficulty occurs both with separate seals, e.g., adhesive seals, and with molded seals (to the applicant's knowledge).

[0017] Another disadvantage of the current state of the art is that the bushings or internally threaded rivets used to screw the fastening screws into the application wall inevitably have a rivet head or flange that protrudes from the application wall into the interface with the cable entry device, thus hindering the necessary sealing in this area. Currently, cable entry device installers attempt to compensate for the thickness of the flanges or rivet heads by inserting an additional gasket or rubber layer approximately 1 mm to 2 mm thick, or by tightening the fastening screws so that the rivet heads are pressed into the plastic material of the cable entry device frame. Neither measure can guarantee the intended tightness.

[0018] Finally, when installing and wall-mounting the cable entry device, both the additional seal and the fixing screws can easily detach from the frame parts and fall off or get lost.

[0019] Therefore, it is the object of the present invention to provide an improved cable feedthrough device having features to eliminate at least some of the disadvantages of the prior art.

[0020] It is a particular concern of the invention to provide a cable entry device having features that simplify assembly and installation and prevent the use of cable entry devices with incorrectly positioned, damaged or interrupted seals.

[0021] It is a further particular object of the invention to provide a cable feedthrough device having features which reduce the number of components to be assembled and ensure their correct mutual positioning.

[0022] It is a further particular object of the invention to provide a cable feedthrough device having features which improve the sealing of the cable feedthrough device against the ingress of moisture and water.

[0023] It is a further particular object of the invention to provide a cable entry device having features which reduce the risk of excessive crushing and damage to the seal during assembly and wall mounting of the cable entry device.

[0024] At least some of the objects are achieved by a cable feedthrough device according to claim 1.

[0025] The dependent claims relate to advantageous and preferred embodiments.

[0026] According to one aspect of the invention, a cable feedthrough device (1) comprises: - a frame (3) having a mounting side (30) facing an application wall (2) and a visible side (31) opposite the mounting side (30), - one or more receiving seats (11) which are delimited by the frame (3) and extend in a cable passage direction (12) transverse to a frame plane (13) of the frame (3), - one or more cable glands (16) made of elastomeric material, which can be positioned in an operating position in the receiving seats (11), - a mounting seal (46) made of elastomeric material, which extends on the mounting side (30) of the frame (3) and protrudes from the frame (3) on the mounting side (30), wherein the mounting seal (46) has a mounting seal color,characterized in that the frame (3) has a different frame color on the mounting side (30) than the color of the mounting seal.

[0027] The color contrast between the seals and the frame parts makes it possible to identify the seal in relation to the frame parts, their mutual positioning and anomalies in shape, position or interruptions of continuity (damage, cuts, twists).

Description of the cable entry device 1

[0029] With reference to the figures, a multiple cable entry device 1 (suitable for obtaining a sealed passage of one or more cables or ducts (not shown) through an application wall 2) comprises:

[0052] - a frame (3) having a mounting side (30) facing an application wall (2) and a visible side (31) opposite the mounting side (30), - one or more receiving seats (11) which are delimited by the frame (3) and extend in a cable passage direction (12) transverse to a frame plane (13) of the frame (3), - one or more cable bushings (16) made of elastomeric material, which can be positioned in the receiving seats (11) in an operating position ( Fig. 4), - a mounting seal (46) made of elastomeric material, which extends on the mounting side (30) of the frame (3) and protrudes from the frame (3) on the mounting side (30), the mounting seal (46) having a mounting seal color.

[0030] According to one aspect of the invention, the frame (3) on the mounting side (30) has a different frame color than the color of the mounting seal.

[0031] The color contrast between the seal and the frame or frame parts makes it possible to identify the seal in relation to the frame parts, their mutual positioning and anomalies in shape, position or interruptions of continuity (damage, cuts, twisting).

[0032] According to one embodiment, the color of the mounting seal over the entire extent of the mounting seal (46) is different from the frame color of a frame surface of the frame (3) which is directly adjacent to and adjacent to the mounting seal (46).

[0033] In this way, the user can detect (without having to perform a detailed visual and tactile inspection along the mounting seal 46) any interruptions in the continuity or deformations of the mounting seal 46, such as indentations, depressions or poor filling.

[0034] Advantageously, the color of the mounting seal is lighter than the color of the frame.

[0035] Possible interruptions in continuity are more easily visible to the human eye when a bright line is on a darker background.

[0036] In a preferred embodiment, the color of the mounting seal is a shade of blue, e.g., light blue or blue, while the color of the frame is preferably gray or black.

[0037] In the area of mechanical assembly, typical contaminants are metal shavings, dust flakes mixed with lubricating grease or residues of self-adhesive labels, whereby the above-mentioned contaminants are more visible on a background with light blue and blue tones, e.g. in the light reflection range with a wavelength between about 435 and 500 nanometers, with other background colors (e.g. red, orange, gray, black).

[0038] In one embodiment, the frame (3) is made of injection-molded polymer material, and the mounting seal (46) is injection-molded onto the frame (3).

[0039] More specifically, it is beneficial: - to form the frame (3) in a first molding step by injection molding and, during this first molding step, to form a cavity system in the frame (3) itself over the extension of the mounting seal (46), - in order then to form the assembly seal (46) by injection moulding in a second moulding step, wherein the already cured cavity system of the frame (3) serves as a core for the injection moulding of the assembly seal (46).

[0040] Already during production, a visual check of the continuity and completeness of the mounting seal (46) can be carried out by means of the color difference between the mounting seal (46) and the frame (3). Detailed description of the frame 3

[0041] According to one embodiment, the frame (3) is rectangular and consists of a base support 4 on a bottom side 5 of the frame 3, an upper support 6 on an upper side 7 of the frame 3 opposite the bottom side 5, two lateral posts 8 extending from the base support 4 to the upper support 6 on two opposite sides 9 of the frame 3, and possibly one or more intermediate posts 10 running parallel to the lateral posts 8 and extending from the base support 4 to the upper support 6 in an intermediate region between the two lateral posts 8.

[0042] The lateral posts 8 and central posts 10 (if present) mutually delimit a plurality of receiving seats 11 which run through the frame 3 in a cable passage direction 12 transversely or orthogonally to a frame plane 13 of the latter.

[0043] The frame 3 is divided into at least a first frame part 14 and a second frame part 15, which in a closed position ( Fig. 1), which represents a configuration of use of the cable entry device 1, can be connected to each other and in an open position ( Fig. 14), which allows the insertion of cable bushings 16 into the receiving seats 11, can be separated from each other.

[0044] In one embodiment, the first frame part 14 forms the base support 4, the two lateral posts 8 and the one or more intermediate posts 10 in a comb-like arrangement ( Fig. 5). The second frame part 15 forms the upper support 6. The first frame part 14 and the second frame part 15 can be connected to one another by means of connecting screws 40, which can be inserted into connecting holes 49 of the upper support 6 and into corresponding connecting holes 49' of the lateral posts 8 and, if provided, one or more intermediate connecting posts 10' and can be screwed into connecting nuts 41, which are received or locked, for example, in a captive and non-rotatable manner (in hexagon sockets, not shown) in the base support 4.

[0045] The free ends (in the open position) of the lateral 8 and central posts 10 have connecting projections 42 which (in the closed position) fit into corresponding connecting recesses 43 of the upper beam 6 ( Fig. 3, Fig. 4) to further stabilize the first frame part 14 and the second frame part 15 and to align them with each other.

[0046] The frame 3, preferably only the first comb-shaped frame part 14, forms several, e.g. four, mounting holes 44 running in the cable passage direction 12 for receiving fastening screws 45 ( Fig. 14).

[0047] The mounting seal (46) made of elastomeric material is also formed by: - a first assembly sealing part (46') which is formed on the first frame part (14) and protrudes from the frame (3) on the assembly side (30), and - a second mounting seal part (46") which is integrally formed on the first frame part (15) and protrudes from the frame (3) on the mounting side (30).

[0048] The need for a separate seal and the risk of incorrect positioning of the seal itself are avoided by molding the mounting seal 46 onto the frame 3.

[0049] The mounting seal 46 extends continuously or in sections, connected in any way by sealing contact, around all the receiving seats 11, in particular along the base support 4, the side posts 8 and the upper support 6, and also around all the mounting holes 44, preferably in a circle around each of the mounting holes 44.

[0050] Preferably, the color of the mounting seal over the entire extent of the first mounting seal part (46') and over the entire extent of the second mounting seal part (46") is different from the frame color of a frame surface of the frame (3) immediately adjacent to and adjacent to the mounting seal (46).

[0051] In order to compensate for factory tolerances of the frame 3, the mounting seal 46 protrudes from the surface of the frame 3 with a sealing height of at least 1.5 mm or in the range of 1 mm to 3 mm, e.g. 2 mm.

[0052] On the other hand, in order to prevent the mounting seal 46 from being squeezed by excessive tightening of the mounting screws 45, the frame 3 forms on the mounting side 30 a plurality of stop elevations 47 next to the mounting seal 46, preferably at or near the mounting holes 44 ( Fig. 9). The stop elevations 47 allow the use of a higher mounting seal 46 compared to the prior art. The elevations 47 can be located on the outside with respect to the mounting holes 44 (in Fig. 9 positions marked 47) to prevent unwanted bulging of the frame 3 when tightening the mounting screws 45. The elevations 47 can also be formed by a projecting edge of the mounting hole 44, as in Fig. 7 shown.

[0053] The cable feedthrough device (1) or the frame 3 further comprises an upper support seal 48 made of elastomeric material, which is formed on the frame 3, in particular only on the second frame part 15, and projects from the upper support 6 into the receiving seats 11 towards the underside 5 of the frame 3 in order to engage the cable feedthroughs 16 adjacent to the upper support 6 in a sealing manner.

[0054] The need for a separate seal and the risk of incorrect positioning of the seal itself are avoided by molding the upper beam seal 48 onto the frame 3.

[0055] It is advantageous that the upper beam seal (48) has a beam seal color, whereby the frame color of the frame (3) on the upper beam (6) is different from the beam seal color.

[0056] In one embodiment, the color of the support seal is lighter than the color of the frame on the upper support (6).

[0057] Advantageously, the color of the carrier seal is light blue or blue, while the frame color on the upper carrier (6) is preferably gray or black.

[0058] In a preferred embodiment, the upper beam seal 48, together with a part of the mounting seal 46 that extends into the upper beam 6, is formed in a single piece and with material continuity ( Fig. 3). In this case, the color of the carrier seal can advantageously be the same as the color of the mounting seal.

[0059] In one embodiment, the mounting seal 46 and the upper beam seal 48 together form a closed loop around all connection holes 49 of the upper beam 6.

[0060] Advantageously, the base support 4 may not have an elastomer seal engaging the cable bushings 16 and may act as a seal by the hard plastic material, e.g., one or more ribs, of the base support 4 directly engaging the adjacent cable bushings 16.

[0061] According to one embodiment ( Fig. 6, Fig. 7, Fig. 15), the mounting holes 44 form a recessed seat (or enlarged outer portion) 50 on the mounting side 30 that is wider than the remainder of the mounting hole 44 and can accommodate a rivet head or socket flange of a rivet or internally threaded socket 52 of the application wall 2. This eliminates the need to provide additional "spacer layers" for the seal between the cable entry device 1 and the application wall 2.

[0062] According to one embodiment, the mounting holes 44 form radially inwardly projecting press projections 51, which are intended to obtain a press fit as a fall protection for the mounting screws 45.

[0063] According to one embodiment, the first frame part 14 and the second frame part 15 are connected in the closed position by a snap connection, e.g. by means of a ratchet ( Fig. 20), can be (pre-)connected to each other to obtain a temporary connection in preparation for a final screw connection using connecting screws. Detailed description of the cable entries 16

[0064] According to one embodiment, the one or more cable glands 16 made of elastomeric material, which can be positioned in the receiving seats 11 in an operating position, comprise: - two opposite first (axial) surfaces 17 facing in a first local direction 18 of the cable bushing 16 (the local direction 18 is in Fig. 16) and in the operating position should face the cable passage direction 12 (the cable passage direction 12 is shown in the Fig. 1, Fig. 4), - two opposite (from top to bottom) second surfaces 19 facing a second local direction 20 of the cable bushing 16 and intended to face the bottom 5 and the top 7 of the frame 3, respectively, in the operating position, - two opposite (lateral) third surfaces 21 facing a third local direction 22 of the cable gland 16 and intended to face the sides 9 of the frame 3 in the operating position, - a through-channel 23 extending in the first local direction 18 and leading into the first two surfaces 17 to accommodate and surround a cable or a line, - a separating cut 24 which extends on one side from the through-channel 23 into only one of the third surfaces 21 and is spaced from the two second surfaces 19 in order to enable the cable or line to be inserted laterally into the through-channel 23.

[0065] The first local direction (or axis) 18, the second local direction (or axis) 20 and the third local direction (or axis) 22 are orthogonal to each other (each with respect to the other two).

[0066] The two second surfaces 19 of the cable entry 16 are both flat, parallel to each other, and preferably smooth (the term "smooth" is to be understood in such a way that a seal is ensured in the contact area between two second surfaces 19, e.g., even in the presence of local or very slight surface structuring, e.g., an overlay of a logo or an alphanumeric code). Alternatively, the second surfaces 19 of the cable entry 16 can be knurled.

[0067] The two third surfaces 21 of the cable gland 16 each form a coupling surface 25 with a plurality of linear grooves 26 and ribs 27 which run parallel to each other and parallel to the second local direction 20, the coupling surface 25 being intended to engage, in the operating position, with a corresponding coupling surface 28 of one of the lateral posts 8 or the intermediate post 10 (if present).

[0068] The coupling surfaces 25 of the cable bushing, preferably the entire third surfaces 21, are symmetrical with respect to a first local plane of symmetry 29 which is orthogonal to the first local direction 18.

[0069] In the operating position, each cable gland 16 can thus be accommodated in the receiving seat 11 in four different orientations, all having the same form of engagement and geometric coupling between the coupling surfaces 25 of the cable gland and the post coupling surfaces 28, preferably all having the same form of engagement and geometric coupling between the entire third surfaces 21 with the receiving seats 11.

[0070] In the operating position, the two cutting surfaces defining the separating cut 24 are constantly in contact with each other and do not affect the external shape of the coupling surface 25 of the cable gland or the third surface 21.

[0071] Therefore, in the operating position, the cable entry device 1 advantageously allows the cable entry holes 16 to face with each of the two first surfaces 17 both towards the mounting side 30 and towards the visible side 31, and with each of the two second surfaces 19 both towards the top side 7 and towards the bottom side 5. Since, in the prior art, installers can easily make mistakes in the orientation of the cable entry holes from top to bottom and from front to back, but never misjudge the direction of the passage channel 23 due to the forced routing of the cables, the new configuration eliminates any doubt about the installation orientation, significantly reduces the risk of incorrect positioning of the cable entry holes 16, speeds up the assembly of the cable entry device 1, and ensures the optimal planned seal in all four intended orientations.

[0072] According to one embodiment ( Fig. 16, Fig. 17) have the grooves 26: - two outer grooves 26', each adjacent to an outer edge 32 formed between the third surface 21 and the first surface 17, - a central groove 26" having a width (in the first local direction 18) which is greater, preferably greater than twice, the width (in the first local direction 18) of the outer groove 26'.

[0073] The ribs 27 indicate: - two separating ribs (27'), each extending between one of the outer grooves 26' and the central groove 26", - two edge ribs 27", which form the outer edges 32.

[0074] The outer grooves 26' have a rectangular cross-section. The central groove 26" has a flat bottom and two curved side surfaces with an arcuate cross-section.

[0075] The separating ribs 27' and the edge ribs 27" all form a flattened, preferably planar rib apex. The edge ribs 27" project beyond the separating ribs 27' in the third local direction.

[0076] Advantageously, in the operating position, the central grooves 26" positively receive corresponding central ribs 36" of the post coupling surface 28, and the outer grooves 26' positively and elastically prestressedly receive corresponding outer ribs 36' of the post coupling surface 28. The outer ribs 36' preferably have a tapered ridge 38 that sinks locally into the elastomeric material of the cable gland 16 and defines a specific sealing line.

[0077] The through-channel 23 has a constant cross-sectional shape, e.g., circular cylindrical and / or oval and / or flattened, possibly with the sole exception of one or more circumferential ribs 33 projecting radially toward the inside of the through-channel 23 to improve the sealing and anti-threading engagement between the cable bushing 16 and the cable or channel enclosed thereby.

[0078] The two first surfaces 17 are preferably parallel to each other and as smooth as possible (apart from any raised markings and the through-channel 23). It is advantageous that the first surfaces 17, and possibly the entire cable feedthrough 16, have a symmetrical shape with respect to the first local plane of symmetry 29.

[0079] Even more advantageously, the second surfaces 19, possibly the entire cable feedthrough 16, have a symmetrical shape with respect to a second local plane of symmetry 34 which is orthogonal to the second local direction 20.

[0080] This allows several cable bushings 16 to be stacked in the receiving seats 11.

[0081] The cable glands 16 are made of elastomeric material, preferably thermoplastic elastomer (TPE).

[0082] The cable feedthroughs 16 may comprise a plurality of said through-channels 23 formed in the same cable feedthrough 16. The at least one through-channel 23 of the cable feedthrough 16 may be formed in a central position relative to an outer contour of the cable feedthrough 16 or in an eccentric position relative to an outer contour of the cable feedthrough 16.

[0083] It is also possible to provide “blind” elastomer cable glands whose external shape is identical to the external shape of the cable glands 16, but without the through-channel 23, in order to close off places which are not used for the passage of cables. Detailed description of the recording seats 11

[0084] The post coupling surface 28 forms a plurality of linear grooves 35 and ribs 36 which run parallel to one another and parallel to the extension of the lateral posts 8 and the intermediate posts 10 (if present), the post coupling surface 28 being intended to come into positive and sealing pressure contact with a corresponding cable entry coupling surface 25 in the operating position.

[0085] According to one embodiment ( Fig. 8) the ribs 36 have: - two outer ribs 36', one of which is closer to the mounting side 30 and the other closer to the visible side 31, - a central rib 36" with a width greater than, preferably greater than twice, the width of the outer rib 36'.

[0086] The grooves 35 have: - two separating grooves 35', each extending between one of the outer ribs 36' and the central rib 36", - additionally, but only in the lateral posts 8 and possibly in a connecting intermediate post 10' (described below), two limiting grooves 35", which limit the post coupling surface 28 on the mounting side 30 and on the visible side 31. Preferably, the limiting grooves 35" are not present in the other intermediate posts 10.

[0087] The outer ribs 36' have a triangular-apical or tapered cross-section, defining the aforementioned tapered ridge. Even more advantageously, the outer ribs 36' form two flat intermediate surfaces 37, which are recessed from the apical ridge 38 and extend along both sides of the apical ridge 38. The central rib 36" has a flat apex and two curved side surfaces with an arcuate cross-section.

[0088] The separating grooves 35' all form a flattened, preferably planar rib apex. The limiting grooves 35", if present, have a substantially angled profile, i.e., they define an outer angled edge or an angled recess of the angled edge of the lateral post 8 or, where applicable, the connecting intermediate post 10'.

[0089] Advantageously, the limiting grooves 35" on the mounting side 30 are triangular in shape and open towards one of the lateral sides 9 and towards the mounting side 30, so that the elastomeric material of the first surface 17 of the cable bushing 16 is directly exposed (and can be pressed) towards the application wall 2.

[0090] Advantageously, the limiting grooves 35" on the visible side 31 have a rectangular U-shape which is open only towards one of the lateral sides 9 in order to form a closing edge 39 which bears (sealingly) against the first surface 17 of the cable duct 16 on the visible side 31.

[0091] The end edge 39 on the visible side 31 extends along the side posts 8, along the at least one connecting intermediate post 10' (if present) as well as along the base support 4 and the upper support 6 and forms a watertight protection around the receiving seats 11.

[0092] The intermediate posts 10, which do not have limiting grooves 35" and end edge 39 and whose cross-sectional area and extension in the cable passage direction 12 is smaller than the cross-sectional area and extension in the cable passage direction 12 of the side posts 8 and the connecting intermediate post 10', are at least partially or completely covered on the assembly side 30 and on the visible side 31 by the edge ribs 27" of the cable bushings 16 used in the operating position ( Fig. 19).

[0093] The post coupling surfaces 28, preferably the entire frame 3, are made of thermoplastic material, e.g., glass fiber-filled polyamide, which has a greater hardness than the elastomeric material of the cable glands 16.

[0094] In one embodiment, the post coupling surfaces 28 without the limiting grooves 35" and without the end edge 39 are symmetrical to the frame plane 13. Instead, the entire receiving seats 11 including the limiting grooves 35" and the end edge 39 are not symmetrical to the frame plane 13 due to the two different functions of interaction with the cable glands 16 on the mounting side 30 and on the visible side 31 ( Fig. ).
