Description

Title of the invention: CABLE PASSAGE DEVICE Technical field of the invention

[0001]

[0001] The present invention relates to a cable passage device which can be mounted on a wall, for example of an electrical cabinet, at a passage opening through which electrical cables or signal cables or fluid tubes are to be guided in an orderly and stable manner in order to ensure a desired degree of sealing and to avoid the risk of damage and unwanted movement of the cables themselves. State of the art

[0002] Cable passage devices, known from document EP1236256 A1, consist of two frame parts which can be connected to each other in the closed position to form a rectangular frame, and which can be separated from each other in the open configuration. These two frame parts delimit several passage housings intended to receive one or more elastic cable glands applied around the cables or tubes, where

[0003] - when the two frame parts are in the open position, the cable glands, as well that the cables or conduits which they surround can be positioned in the passage housings or removed from the passage housings,

[0004] - when the two frame parts are in the closed position, the cable glands are in close contact with each other and against the frame parts, and form with the frame parts a substantially watertight plate, crossed by the cables surrounded by the cable glands.

[0005] It is also known to obtain a first U-shaped or comb-shaped frame part with a base crosspiece from which two lateral uprights and, possibly, one or more other intermediate uprights protrude, the passage seats being delimited between two adjacent uprights, respectively, thus allowing temporary insertion and positioning of the cable glands in the first frame part only.

[0006] It is further known to provide a second frame part in the form of a crosspiece connectable to the initially free ends of the lateral and intermediate uprights of the first frame part to close the passage seats and tighten the cable glands in the closed position.

[0007] It is also known to configure the second frame part in a U-shape or comb shape, substantially mirrored relative to the shape of the first frame part. frame, and can be connected to the first frame part to close the passage seats and tighten the cable glands in the closed position.

[0008] It is also known to obtain the cable glands with a grooved or ribbed outer surface, and to obtain the passage seats of the frame parts with a grooved or ribbed intrados surface, in order to increase the localized contact pressure, and therefore the sealing, between the passage seats and the cable glands when the cable passage device is in the closed position.

[0009] The cable passage device is fixed to the application wall by screwing using fixing screws, for example four in number, and with the interposition of a suitable seal between the cable passage device and the wall itself.

[0010] In order to allow the fixing screws to be screwed onto the application wall (typically made of thin sheet metal or a material unsuitable for tightening the screws), it is known to apply suitable sockets or internally threaded rivets to the application wall.

[0011] The cable passage devices of the state of the art nevertheless have several drawbacks.

[0012] Correct positioning of an additional seal (initially separate from the frame of the cable passage device) between the cable passage device and the wall is not practical.

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

[0014] Frame parts made of synthetic material by molding have flatness tolerances which are added to the flatness tolerances of the application wall and are not always entirely compensated by the elastic deformation of the additional seal interposed between the cable passage device and the application wall.

[0015] To date, the continuity of the sealing barrier is not ensured between the interface zones between the cable glands and the passage seats and the sealing zones between the different parts of the frame and the sealing zones between the parts of the frame and the wall.

[0016] In the prior art, the joint between the cable passage device and the wall is the same gray or black color as the frame elements. The lack of color contrast between the joints and the frame elements prevents separate viewing of the joint from the frame elements, its correct positioning and anomalies in shape, continuity (damage, cuts, twists) or positioning of the seals. This difficulty arises both with separate seals, for example adhesive, and with overmolded seals (internal knowledge of the applicant).

[0017] Another disadvantage of the prior art is that, in order to allow the fastening screws to be screwed onto the application wall, the threaded sockets or rivets must necessarily have a head or flange protruding from the application wall up to the interface with the cable passage device, which makes sealing impossible to ensure in this area. Currently, installers of cable passage devices try to compensate for the thickness of the flanges or rivet heads by inserting an additional sealing or rubber layer of approximately 1 to 2 mm thickness, or by tightening the fastening screws so as to press the rivet heads into the plastic material of the device frame. Both of these measures do not guarantee the intended sealing.

[0018] Finally, when assembling and wall-mounting the cable passage device, the additional gasket and fixing screws can easily detach from the frame parts and fall off or get lost. Presentation of the invention

[0019] The object of the present invention is therefore to provide an improved cable passage device, having characteristics making it possible to avoid at least some of the drawbacks of the state of the art.

[0020] The invention relates in particular to a cable passage device having characteristics such as simplifying assembly and mounting and preventing the use of cable passage devices whose joints are poorly positioned, damaged or have interruptions in continuity.

[0021] The invention also has the particular object of providing a cable passage device having characteristics such as reducing the number of components to be assembled and ensuring correct mutual positioning of these.

[0022] Another particular object of the invention is to provide a cable passage device having characteristics such that they improve the sealing of the cable passage device against the penetration of humidity and water.

[0023] Another particular object of the invention is to provide a cable passage device having characteristics such as reducing the risk of excessive compression and damage to the seals during assembly and wall mounting of the cable passage device.

[0024] At least some of the objectives are achieved by a cable passage 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 passage device comprises:

[0027] - a frame forming a mounting face intended to face an application wall and a visible face opposite the mounting face,

[0028] - one or more receiving housings delimited by the frame and passing through a direction of cable passage transverse to a frame plane of the frame,

[0029] - one or more cable glands made of elastomer material, positionable in the receiving housings in operating position,

[0030] - a mounting gasket, made of elastomeric material, extending over the mounting face of the frame and projecting from the frame onto the mounting face, said mounting gasket having a mounting gasket color,

[0031] characterized in that, on the mounting face, the frame has a frame color different from the color of the mounting gasket.

[0032] Thanks to the color contrast between the joints and the frame parts, it is possible to visualize the joint in relation to the frame parts, their mutual positioning and anomalies in shape, position or interruptions in continuity (damage, cuts, twists). Detailed description of the invention

[0056] Description of the cable passage device 1

[0057] With reference to the figures, a multiple cable passage device 1 (i.e. adapted to obtain a sealed passage of one or more cables or conduits (not shown) through an application wall 2) comprises:

[0058] - a frame 3 forming a mounting face 30 intended to face a wall application 2 and a visible face 31 opposite the mounting face 30,

[0059] - one or more receiving housings 11 delimited by the frame 3 and passing through a cable passage direction 12 transverse to a frame plane 13 of the frame 3,

[0060] - one or more cable glands 16 made of elastomeric material, positionable in the receiving housings 11 in operating position ([Fig.4]),

[0061] - a mounting seal 46, made of elastomeric material, extending over the mounting face 30 of the frame 3 and protruding from the frame 3 onto the mounting face 30, said mounting gasket 46 having a mounting gasket color.

[0062] According to one aspect of the invention, the frame 3 has, on the mounting face 30, a frame color different from the color of the mounting seal.

[0063] Thanks to the color contrast between the seal and the frame or parts of the frame, it is possible to visualize the seal in relation to the parts of the frame, a mutual positioning of these and anomalies of shape, position or interruptions of continuity (damage, cuts, twists).

[0064] According to one embodiment, over the entire extension of the mounting seal 46, the color of the mounting seal is different from the color of the frame of a frame surface of the frame 3 immediately adjacent and adjacent to the mounting seal 46.

[0065] This helps the user identify (without having to perform a thorough visual and tactile inspection along the mounting joint 46), interruptions in continuity or deformations of the mounting joint 46, such as draws, depressions or poor filling, for example.

[0066] Advantageously, the color of the mounting seal is lighter than the color of the frame.

[0067] Possible interruptions in continuity are more apparent to the human eye if there is a light line on a darker background.

[0068] According to a preferred embodiment, the color of the mounting gasket is a shade of blue, for example light blue or blue, while the color of the frame is preferably gray or black.

[0069] In the field of mechanical assembly, typical impurities include metal shavings, dust plates mixed with lubricating grease or remaining self-adhesive labels, compared to other background colors (e.g., red, orange, gray, black), the above impurities are more visible on a background having shades of light blue and blue, for example, in the reflection range of light with a wavelength between about 435 and 500 nanometers.

[0070] According to one embodiment, the frame 3 is made of injection-molded polymer material and the mounting seal 46 is overmolded onto the frame 3.

[0071] More specifically, it is advantageous:

[0072] - to form the frame 3 in a first forming step by injection molding and to form, during this first forming step, in the frame 3 itself, a system of cavities on the extension of the mounting joint 46,

[0073] - to then form the mounting seal 46 in a second forming step by injection molding, in which the already hardened cavity system of the frame 3 serves as a core for the injection molding of the mounting gasket 46.

[0074] Already during manufacturing, the difference in color between the mounting seal 46 and the frame 3 allows a visual check of the continuity and completeness of the mounting seal 46.

[0075] Detailed description of frame 3

[0076] According to one embodiment, the frame 3 is rectangular and formed of a base crosspiece 4 on a lower side 5 of the frame 3, of an upper crosspiece 6 on an upper side 7 of the frame 3 opposite the lower side 5, of two lateral uprights 8 extending from the base crosspiece 4 to the upper crosspiece 6 on two opposite lateral sides 9 of the frame 3, and possibly of one or more intermediate uprights 10 parallel to the lateral uprights 8 and extending from the base crosspiece 4 to the upper crosspiece 6 in an intermediate region between the two lateral uprights 8.

[0077] The lateral 8 and intermediate 10 (if provided) uprights mutually delimit a plurality of receiving housings 11 passing through in a cable passage direction 12, transverse or orthogonal to a frame plane 13 of the frame 3,

[0078] The frame 3 is divided at least into a first frame part 14 and a second frame part 15 connectable to each other in a closed position ([Fig.l]), which is a configuration of use of the cable passage device 1, and separable from each other in an open position ([Fig. 14]) which allows cable glands 16 to be inserted into the receiving housings 11.

[0079] According to one embodiment, the first part of the frame 14 forms the base crosspiece 4, the two lateral uprights 8 and the intermediate upright(s) 10, arranged in a comb ([Fig.5]). The second part of the frame 15 forms the upper crosspiece 6. The first and second parts of the frame 14 and 15 can be connected to each other by fixing screws 40, inserted into the connection holes 49 of the upper crosspiece 6 and into the corresponding connection holes 49' of the lateral uprights 8 and, where appropriate, of one or more intermediate uprights 10', and screwed into fixing nuts 41, for example, fixed or fitted in a fixed and non-rotatable manner (in hexagonal housings, not shown) in the base crosspiece 4.

[0080] The free ends (in the open position) of the lateral 8 and intermediate 10 uprights comprise connecting projections 42 inserted (in the closed position) into corresponding connecting recesses 43 of the upper cross member 6 (Figures 3, 4) to further stabilize and align the first frame part 14 and the second frame part 15 relative to each other.

[0081] The frame 3, preferably only the first comb-shaped frame part 14, forms a plurality, for example four, of mounting through-holes 44 extending in the direction of passage of the cable 12, for receiving mounting screws 45 ([Fig. 14]) which can be screwed into the application wall 2.

[0082] The mounting seal 46 made of elastomeric material is also formed by:

[0083] - a first mounting joint piece 46' overmolded on the first part of frame 14 and protruding from frame 3 on mounting face 30, and

[0084] - a second part of 46" mounting joint overmolded on the second part of frame 15 and protruding from frame 3 on mounting face 30.

[0085] The need for a separate seal and the risk of incorrect positioning of the seal itself are avoided by overmolding the mounting seal 46 onto the frame 3.

[0086] The mounting seal 46 extends continuously or in sections connected to each other in any manner by sealing contact, around all the receiving housings 11, in particular along the base crosspiece 4, the side uprights 8 and the upper crosspiece 6, as well as around all the mounting holes 44, preferably in a circular manner around each of the mounting holes 44.

[0087] Preferably, over the entire extension of the first mounting joint portion 46' and over the entire extension of the second joint portion 46", the color of the mounting joint is different from the color of the frame of a frame surface of the frame 3 immediately adjacent and adjacent to the mounting joint 46.

[0088] In order to compensate for the factory tolerances of the frame 3, the mounting gasket 46 protrudes from the surface of the frame 3 with a gasket height of at least 1.5 mm, or in the range of 1 mm to 3 mm, for example 2 mm.

[0089] On the other hand, in order to prevent the mounting gasket 46 from being compressed by excessive tightening of the mounting screws 45, the frame 3 forms, on the mounting face 30, a plurality of stop projections 47 adjacent to the mounting gasket 46, preferably at or near the mounting holes 44 ([Fig. 9]). These stop projections 47 allow a higher mounting gasket 46 to be used than in the prior art. The projections 47 may be located outside the mounting holes 44 (positions indicated by the reference numeral 47 in [Fig. 9]) in order to prevent undesirable buckling of the frame 3 under the effect of tightening the mounting screws 45. The projections 47 may also, or only, be formed, for example, by a projecting edge of the mounting hole 44, as illustrated in [Fig. 7].

[0090] The cable passage device 1 or the frame 3 further comprises an upper crosspiece seal 48, made of elastomeric material, overmolded onto the frame 3, in particular onto the second frame part 15 only and projecting from the upper crosspiece 6 into the receiving housings 11 towards the lower side 5 of the frame 3, in order to tightly engage the cable glands 16 adjoining the upper crosspiece 6.

[0091] The need for a separate seal and the risk of incorrect positioning of the seal itself are avoided by overmolding the upper crossmember seal 48 onto the frame 3.

[0092] Advantageously, the upper cross member seal 48 has a cross member seal color,

[0093] the color of the frame 3 at the upper cross member 48 being different from the color of the cross member seal.

[0094] According to one embodiment, the color of the crossbar seal is lighter than the color of the frame at the upper crossbar 6.

[0095] Advantageously, the color of the crossbar seal is light blue or blue, while the color of the frame at the upper crossbar 6 is preferably gray or black.

[0096] According to a preferred embodiment, the upper crossmember seal 48 is formed with a portion of the mounting seal 46 extending into the upper crossmember 6, in one piece and with continuity of material ([Fig.3]). In this case, advantageously, the color of the crossmember seal may be identical to that of the mounting seal.

[0097] According to one embodiment, the mounting gasket 46 and the upper cross member gasket 48 together form a closed loop around all the connection holes 49 of the upper cross member 6.

[0098] Advantageously, the base crossmember 4 may not have an elastomeric seal engaging the grommets 16 and may act as a seal by directly engaging the hard plastic material, for example, of one or more ribs, of the base crossmember 4 with the grommets 16 adjacent thereto.

[0099] According to one embodiment (Figures 6, 7, 15), the mounting holes 44 form a recessed seat (or enlarged outer portion) 50 on the mounting face 30, which is wider than the remaining portion of the mounting hole 44 and adapted to receive a rivet head or socket flange of a rivet or threaded socket 52 of the application wall 2. This avoids the need to provide further layers of "spacer" seal between the cable passage device 1 and the application wall 2.

[0100] According to one embodiment, the mounting holes 44 form interference projections 51 projecting radially inward and provided to achieve interference engagement with the mounting screws 45 as an anti-fall measure for the mounting screws.

[0101] According to one embodiment, the first frame part 14 and the second frame part 15 are (pre-)connectable to each other in the closed position by means of a snap-on connection, for example a ratchet ([Fig.20]), in order to obtain a temporary connection with a view to definitive screwing by means of connecting screws.

[0102] Detailed description of the cable glands 16

[0103] According to one embodiment, the cable gland(s) 16 made of elastomer material, positionable in the receiving housings 11 in the operating position, comprise:

[0104] - two first opposite (axial) faces 17, turned in a first direction local 18 of the cable gland 16 (local direction 18 indicated in [Fig. 16]) and intended, in the operating position, to face the direction of passage of the cable 12 (direction of passage of the cable 12 indicated in figures 1, 4),

[0105] - two second opposite faces (top-bottom) 19 facing a second direction local 20 of the cable gland 16 and intended, in the operating position, to face respectively the lower side 5 and the upper side 7 of the frame 3,

[0106] - two third opposite (lateral) faces 21 facing a third direction local 22 of the cable gland 16 and intended, in the operating position, to face respectively the two lateral sides 9 of the frame 3,

[0107] - a through channel 23 extending along the first local direction 18 and opening into the first two faces 17 to receive and surround a cable or a conduit,

[0108] - a separation cut 24 extending unilaterally from the through channel 23 in only one of the third faces 21 and spaced from the two second faces 19, to allow lateral insertion of the cable or conduit into the through channel 23.

[0109] 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),

[0110] The two second faces 19 of the cable gland 16 are both flat, parallel to each other and preferably smooth; the term smooth should be understood as smooth to such an extent that it nevertheless ensures a seal in the contact interface of the two second faces 19, for example, also in the presence of a local or very weak surface structuring, for example, a superposition of a logo or an alphanumeric code. Alternatively, the second faces 19 of the cable gland 16 may be knurled.

[0111] The two third faces 21 of the cable grommet 16 each form a cable grommet coupling surface 25 with a plurality of linear grooves 26 and ribs 27, parallel to each other and parallel to the second local direction 20, said cable grommet coupling surface 25 being intended to engage, in the operating position, with a corresponding vertical coupling surface 28 of one of the lateral 8 and intermediate 10 uprights (if provided), respectively.

[0112] The coupling surfaces of the eyelets 25, preferably all of the third faces 21, are symmetrical with respect to a first local plane of symmetry 29 orthogonal to the first local direction 18.

[0113] In the operating position, each cable gland 16 can thus be housed in the receiving housing 11, according to four different orientations, all having the same form of engagement and geometric coupling between the coupling surfaces of the cable gland 25 and the vertical coupling surfaces 28, preferably all having the same form of engagement and geometric coupling between all of the third faces 21 with the receiving housings 11.

[0114] In the operating position, two cutting surfaces defining the separation cut 24 are in continuous contact with each other and do not affect the outer shape of the cable grommet coupling surface 25 or the third face 21.

[0115] Therefore, in the operating position, the cable passage device 1 advantageously allows the cable glands 16 to be oriented, with each of the two first faces 17, both towards the mounting face 30 and towards the visible face 31, and with each of the two second faces 19, both towards the upper side 7 and towards the lower side 5. In the state of the art, since fitters can easily miscalculate the top-bottom orientation and the front-back orientation of the cable glands, but never miscalculate the direction of the through channel 23 due to the forced routing of the cables, the new configuration eliminates any doubt about the installation orientation, considerably reduces the risk of incorrect positioning of the cable glands 16, speeds up the assembly of the cable passage device 1 and guarantees the intended optimal sealing in all four intended orientations.

[0116] According to one embodiment (figures 16, 17), the grooves 26 comprise:

[0117] - two outer grooves 26', each adjacent to an outer edge 32 formed between the third side 21 and the first side 17,

[0118] - a central groove 26" having a width (in the first local direction 18), greater, preferably greater than double, the width (in the first local direction 18) of the outer groove 26'.

[0119] The ribs 27 comprise:

[0120] - two separating ribs 27' extending respectively between one of the grooves outer 26' and the central groove 26",

[0121] - two edge ribs 27" forming the outer edges 32.

[0122] The outer grooves 26' have a rectangular section. The central groove 26" has a flat bottom and two lateral surfaces curved in an arc of a circle.

[0123] The separating ribs 27' and the edge ribs 27" all form a flattened, preferably planar, rib apex. The edge ribs 27" project in the third local direction beyond the separating ribs 27'.

[0124] Advantageously, in the operating position, the central grooves 26" receive, with form coupling, corresponding central ribs 36" of the vertical coupling surface 28, and the outer grooves 26' receive, with form coupling and elastic preload, corresponding outer ribs 36' of the vertical coupling surface 28. The outer ribs 36' preferably have an apical edge 38 so as to locally sink into the elastomeric material of the cable gland 16, defining a certain sealing line.

[0125] The through channel 23 has a constant cross-sectional shape, for example cylindrical, circular and / or oval and / or flattened, possibly with the sole exception of one or more several circumferential ribs 33 projecting radially inwardly from the through channel 23 to improve the sealing and anti-unscrewing engagement between the cable gland 16 and the cable or conduit encompassed by the latter.

[0126] The first two faces 17 are preferably parallel to each other and possibly smooth (with the exception of any raised markings and the through channel 23). Advantageously, the first faces 17, and possibly the entire cable gland 16, have a symmetrical shape relative to the first local plane of symmetry 29.

[0127] More advantageously, the second faces 19, or even the entire cable gland 16, have a symmetrical shape relative to a second local plane of symmetry 34, orthogonal to the second local direction 20.

[0128] This makes it possible to stack a plurality of cable glands 16 in the receiving housings 11.

[0129] The cable glands 16 are made of elastomeric material, preferably thermoplastic elastomer (TPE).

[0130] The cable grommets 16 may comprise a plurality of through channels 23 formed in the same cable grommet 16. The one or more through channels 23 of the cable grommet 16 may be formed in a central position relative to an outer contour of the cable grommet 16, or in an eccentric position relative to an outer contour of the cable grommet 16.

[0131] “Blind” elastomeric cable glands with an external shape identical to the external shape of the cable glands 16 may also be provided, but without the through channel 23, intended to block positions not used for the passage of cables.

[0132] Detailed description of the reception accommodations 11

[0133] The vertical coupling surface 28 forms a plurality of linear grooves 35 and ribs 36, parallel to each other and parallel to the extension of the lateral 8 and intermediate 10 uprights (if present), said vertical coupling surface 28 being intended to engage, in the operating position, with a corresponding eyelet coupling surface 25 with a coupling contact of form and sealing pressure.

[0134] According to one embodiment ([Fig.8]), the ribs 36 comprise:

[0135] - two outer ribs 36', one closer to the mounting face 30 and the other closer to the visible face 31,

[0136] - a central rib 36" having a width greater, preferably greater than double the width of the outer rib 36'.

[0137] The grooves 35 comprise:

[0138] - two separation grooves 35' extending respectively between one of the ribs exterior 36' and the central rib 36",

[0139] - only in the side uprights 8 and possibly in an upright intermediate connecting member 10' (which will be described below), in addition two delimiting grooves 35" delimiting the coupling surface of the uprights 28 on the mounting face 30 and on the visible face 31. Preferably, the delimiting grooves 35" are not present in the remaining intermediate uprights 10.

[0140] The outer ribs 36' have a triangular, or canine, section defining the apical ridge above. More advantageously, they form two planar intermediate surfaces 37, set back from the apical ridge 38 and extending on either side thereof. The central rib 36" has a planar apex and two lateral surfaces curved in an arc of a circle.

[0141] The separating grooves 35' all form a flattened, preferably planar, rib apex. The delimiting grooves 35", when present, have a substantially angular profile, that is to say they define an outer corner edge or an angular recess of the corner edge of the lateral upright 8 or, possibly, of the intermediate connecting upright 10'.

[0142] Advantageously, the delimiting grooves 35" on the mounting face 30 are triangular in shape, open towards one of the lateral sides 9 and towards the mounting face 30, so as to expose (and be able to compress) the elastomeric material of the first face 17 of the cable gland 16 directly towards the application wall 2.

[0143] Advantageously, the delimiting grooves 35" on the visible face 31 have a rectangular U-shape, open only towards one of the lateral sides 9, so as to form a closing edge 39 which engages (in a sealed manner) with the first face 17 of the cable gland 16 on the visible face 31.

[0144] The closing edge 39 on the visible face 31 extends along the lateral uprights 8, along the at least one intermediate connecting upright 10' (if provided), as well as along the base crosspiece 4 and along the upper crosspiece 6 forming a sealed protection all around the receiving housings 11.

[0145] The intermediate uprights 10, which do not have delimiting grooves 35" or closing edge 39, and which have a section and an extension in the direction of passage of the cable 12 less than a section and an extension in the direction of passage of the cable 12 of the lateral uprights 8 and of the intermediate connecting upright 10', are at least partially or completely covered, on the mounting face 30 and on the visible face 31, by the edge ribs 27" of the cable glands 16 inserted in the operating position ([Fig. 19]).

[0146] The vertical coupling surfaces 28, preferably the entire frame 3, are made of thermoplastic material, for example of polyamide filled with glass fibers, having a hardness greater than that of the elastomeric material of the cable glands 16.

[0147] According to one embodiment, the vertical coupling surfaces 28, without the delimiting grooves 35" and without the closing edge 39, are symmetrical with respect to the plane of the frame 13. On the contrary, the set of receiving housings 11, including the delimiting grooves 35" and the closing edge 39, are not symmetrical with respect to the plane of the frame 13, due to the two different functions of interaction with the cable glands 16 on the mounting face 30 and on the visible face 31 ([Fig. 19]).
