Description

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

[0001]

[0001] The present invention relates to a cable passage device that can to 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 must 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 entry devices, known from document EP1236256 A1, consist of two frame sections that can be joined together in the closed position to form a rectangular frame, and separated from each other in the open configuration. These two frame sections define several passageways intended to receive one or more elastic cable glands applied around the cables or tubes, where

[0003] - when both frame parts are in the open position, the cable guides, thus that the cables or conduits they surround can be positioned in the passageways or removed from the passageways,

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

[0005] It is also known to obtain a first part of the frame in the shape of a U or comb with a base cross member from which two lateral uprights and, optionally, 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 passages in the first part of the frame only.

[0006] It is further known to provide a second frame part in the form of a crossbar 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 passages in the closed position.

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

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

[0009] The cable passage device is fixed to the application wall by screwing it in place using fixing screws, for example four of them, 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 of a material unsuitable for screw tightening), it is known to apply suitable bushings or internally threaded rivets to the application wall.

[0011] However, prior art cable passage devices have several drawbacks.

[0012] The correct positioning of an additional joint (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 in addition to the flatness tolerances of the application wall and are not always fully compensated by the elastic deformation of the additional joint 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 areas between the cable passages and the passage seats and the sealing areas between the different parts of the frame and the sealing areas between the parts of the frame and the wall.

[0016] In the prior art, the joint between the cable entry 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 visualization of the joint from the frame elements, its correct positioning, and anomalies in shape, continuity (damage, cuts, twists), or positioning of the joints. This difficulty arises both with separate joints, for example adhesive, and with overmolded joints (internal knowledge of the applicant).

[0017] Another drawback of the prior art lies in the fact that, in order to allow the fixing screws to be screwed onto the application wall, the threaded sockets or rivets must necessarily have a head or flange extending beyond the application wall to the interface with the cable entry device, making it impossible to ensure a seal in this area. Currently, installers of cable entry devices attempt to compensate for the thickness of the flanges or rivet heads by inserting an additional layer of sealant or rubber approximately 1 to 2 mm thick, or by tightening the fixing screws in such a way as to embed the rivet heads into the plastic material of the device frame. Neither of these measures guarantees the intended seal.

[0018] Finally, during assembly and wall mounting of the cable passage device, the additional seal and fixing screws can easily detach from the frame parts and fall or be lost. Presentation of the invention

[0019] The object of the present invention is therefore to provide an improved cable passage device, having characteristics that allow at least some of the disadvantages of the prior art to be avoided.

[0020] The invention relates in particular to a cable passage device having characteristics such as the simplification of assembly and mounting and the prevention of 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 components.

[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 moisture 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 joints during assembly and wall mounting of the cable passage device.

[0024] According to one aspect of the invention, a cable routing device comprises:

[0025] - a frame forming a mounting face intended to face an application wall and a visible face opposite the mounting face,

[0026] - one or more reception accommodations delimited by the frame and passing through a direction of cable passage transverse to a frame plane of the frame,

[0027] - one or more cable glands made of elastomeric material, positionable in the reception accommodations in operating position

[0028] - a mounting seal, made of elastomeric material, extending over the mounting face of the frame and projecting from the frame on the mounting face, said mounting joint having a mounting joint color,

[0029] characterized in that, on the mounting face, the frame has a frame color different from the color of the mounting joint.

[0030] 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

[0054] Description of the cable passage device 1

[0055] With reference to the figures, a multi-cable passage device 1 (i.e., adapted to obtain a watertight passage of one or more cables or conduits (not shown) through an application wall 2) comprises:

[0056] - 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,

[0057] - one or more reception accommodations 11 delimited by frame 3 and passing through a cable passage direction 12 transverse to a frame plane 13 of frame 3,

[0058] - one or more cable passages 16 made of elastomeric material, positionable in the receiving housings 11 in operating position ([Fig.4]),

[0059] - a mounting seal 46, made of elastomeric material, extending over the mounting face 30 of frame 3 and projecting from frame 3 on mounting face 30, said mounting joint 46 having a mounting joint color.

[0060] 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 joint.

[0061] Thanks to the color contrast between the joint and the frame or parts of the frame, it is possible to visualize the joint 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).

[0062] According to one embodiment, over the entire extension of the mounting joint 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.

[0063] This helps the user to 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 pulls, depressions or poor filling, for example.

[0064] Advantageously, the color of the mounting joint is lighter than the color of the frame.

[0065] Possible interruptions in continuity are more apparent to the human eye if there is a light line on a darker background.

[0066] According to a preferred embodiment, the color of the mounting joint is a shade of blue, for example light blue or blue, while the color of the frame is preferably grey or black.

[0067] In the field of mechanical assembly, typical impurities include metal chips, dust plates mixed with lubricating grease or leftover sticky 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 light reflection range with a wavelength between approximately 435 and 500 nanometers.

[0068] According to one embodiment, the frame 3 is made of injection-molded polymer material and the mounting joint 46 is overmolded onto the frame 3.

[0069] More specifically, it is advantageous:

[0070] - to form the frame 3 in a first step of forming by injection molding and to form, during this first forming stage, within frame 3 itself, a system of cavities on the extension of the mounting joint 46,

[0071] - to then form the mounting joint 46 in a second forming step by injection molding, in which the already hardened cavity system of frame 3 serves as a core for the injection molding of the mounting joint 46.

[0072] Even during manufacturing, the difference in color between the mounting joint 46 and the frame 3 allows for a visual check of the continuity and integrity of the mounting joint 46.

[0073] Detailed description of frame 3

[0074] According to one embodiment, the frame 3 is rectangular and formed of a base cross member 4 on a lower side 5 of the frame 3, an upper cross member 6 on an upper side 7 of the frame 3 opposite the lower side 5, two lateral uprights 8 extending from the base cross member 4 to the upper cross member 6 on two opposite lateral sides 9 of the frame 3, and optionally one or more intermediate uprights 10 parallel to the lateral uprights 8 and extending from the base cross member 4 to the upper cross member 6 in an intermediate region between the two lateral uprights 8.

[0075] The side uprights 8 and intermediate uprights 10 (if provided) 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,

[0076] The frame 3 is divided into at least a first frame part 14 and a second frame part 15 which can be connected to each other in a closed position ([Fig. 1]), which is a configuration for using the cable passage device 1, and which can be separated from each other in an open position ([Fig. 14]) which allows cable glands 16 to be inserted into the receiving slots IL

[0077] According to one embodiment, the first part of the frame 14 forms the base cross member 4, the two side uprights 8, and the intermediate upright(s) 10, arranged in a comb-like configuration ([Fig. 5]). The second part of the frame 15 forms the top cross member 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 top cross member 6 and into the corresponding connection holes 49' of the side uprights 8 and, where applicable, of one or more intermediate uprights 10', and screwed into fixing nuts 41, for example, fixed or fitted in a fixed and non-rotating manner (in hexagonal recesses, not shown) in the base cross member 4.

[0078] The free ends (in open position) of the side posts 8 and intermediate posts 10 include connecting projections 42 inserted (in 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 with respect to each other.

[0079] The frame 3, preferably only the first comb-shaped frame part 14, forms a plurality, for example four, of through mounting holes 44 extending in the direction of passage of the cable 12, to receive mounting screws 45 ([Fig. 14]) which can be screwed into the application wall 2.

[0080] The mounting joint 46 made of elastomeric material is also formed by:

[0081] - a first 46' mounting gasket piece overmolded onto the first part of frame 14 and extending beyond frame 3 on mounting face 30, and

[0082] - a second 46" mounting joint part overmolded onto the second part of frame 15 and extending beyond frame 3 on mounting face 30.

[0083] 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.

[0084] The mounting joint 46 extends continuously or in sections connected together in any way by sealing contact, around all the receiving housings 11, in particular along the base cross member 4, the side uprights 8 and the top cross member 6, as well as around all the mounting holes 44, preferably in a circular fashion around each of the mounting holes 44.

[0085] Preferably, over the entire extension of the first part of the mounting joint 46' and over the entire extension of the second part of the joint 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.

[0086] In order to compensate for the factory tolerances of the frame 3, the mounting joint 46 protrudes from the surface of the frame 3 with a joint height of at least 1.5 mm, or in the range of 1 mm to 3 mm, for example 2 mm.

[0087] Furthermore, to prevent the mounting joint 46 from being compressed by excessive tightening of the mounting screws 45, the frame 3 forms several stop projections 47 on the mounting face 30, adjacent to the mounting joint 46, preferably at or near the mounting holes 44 ([Fig. 9]). These stop projections 47 allow the mounting joint 46 to be used higher than in the prior art. The projections 47 can be located outside the mounting holes 44 (positions indicated by the reference numeral 47 in [Fig. 9]) to prevent undesirable buckling of the frame 3 under the effect of tightening the mounting screws 45. The projections 47 can also, or only, be formed, for example, by a protruding edge of the mounting hole 44, as illustrated in [Fig. 7].

[0088] The cable passage device 1 or the frame 3 further includes an upper cross member 48, made of elastomeric material, overmolded on the frame 3, in particular on the second part of the frame 15 only and projecting from the upper cross member 6 into the receiving housings 11 towards the lower side 5 of the frame 3, in order to engage the cable passages 16 adjacent to the upper cross member 6 in a watertight manner.

[0089] The need for a separate seal and the risk of incorrect positioning of the seal itself are avoided by overmolding the upper cross member seal 48 onto the frame 3.

[0090] Advantageously, the upper cross member joint 48 has a cross member joint color,

[0091] the color of the frame 3 to the upper cross member 48 being different from the color of the cross member joint.

[0092] According to one embodiment, the color of the cross joint is lighter than the color of the frame at the upper cross member 6.

[0093] Advantageously, the color of the cross joint is light blue or blue, while the color of the frame at the upper cross member 6 is preferably grey or black.

[0094] According to a preferred embodiment, the upper cross member joint 48 is formed with a portion of the mounting joint 46 extending into the upper cross member 6, in one piece and with material continuity ([Fig. 3]). In this case, advantageously, the color of the cross member joint can be identical to that of the mounting joint.

[0095] According to one embodiment, the mounting joint 46 and the upper cross member joint 48 together form a closed loop around all the connection holes 49 of the upper cross member 6.

[0096] Advantageously, the base cross member 4 may not have an elastomer seal engaging the cable glands 16 and may act as a seal by directly engaging the hard plastic material, for example, of one or more ribs, of the base cross member 4 with the cable glands 16 adjacent thereto.

[0097] According to one embodiment (Figures 6, 7, 15), the mounting holes 44 form a recessed seat (or enlarged outer part) 50 on the mounting face 30, which is wider than the remaining part of the mounting hole 44 and adapted to accommodate a rivet head or a socket flange of a rivet or threaded socket 52 of the application wall 2. This avoids the need to provide other "spacer" gasket layers between the cable passage device 1 and the application wall 2.

[0098] According to one embodiment, the mounting holes 44 form interference projections 51 projecting radially inwards and intended to achieve interference engagement with the mounting screws 45 as an anti-fall measure for the mounting screws.

[0099] 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-fit ​​connection, for example a ratchet ([Fig.20]), in order to obtain a temporary connection for the purpose of final screwing by means of connecting screws.

[0100] Detailed description of cable grommets 16

[0101] According to one embodiment, the cable gland(s) 16 made of elastomeric material, which can be positioned in the receiving housings 11 in the operating position, comprise:

[0102] - two first (axial) opposite faces 17, rotated along a first direction local 18 of the cable pass-through 16 (local direction 18 indicated on [Fig. 16]) and intended, in operating position, to face the direction of passage of the cable 12 (direction of passage of the cable 12 indicated on figures 1, 4),

[0103] - two second opposite faces (top-bottom) 19 turned towards 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,

[0104] - two third opposite (lateral) faces 21 turned towards 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,

[0105] - a channel crossing 23 extending along the first local direction 18 and opening into the first two faces 17 to receive and surround a cable or conduit,

[0106] - a separation cut 24 extending unilaterally from the traversing 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 channel passing through 23.

[0107] 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),

[0108] 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 at the contact interface of the two second faces 19, for example, even in the presence of local or very slight surface texture, for example, an overlay of a logo or an alphanumeric code. Alternatively, the second faces 19 of the cable gland 16 may be knurled.

[0109] The two third faces 21 of the cable gland 16 each form a cable gland 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 gland coupling surface 25 being intended to engage, in the operating position, with a corresponding vertical coupling surface 28 of one of the lateral uprights 8 and intermediate uprights 10 (if provided), respectively.

[0110] The coupling surfaces of the eyelets 25, preferably the set of third faces 21, are symmetric with respect to a first local symmetry plane 29 orthogonal to the first local direction 18.

[0111] 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 the third faces 21 with the receiving housings 11.

[0112] In the operating position, two cutting surfaces defining the separation cut 24 are in continuous contact with each other and do not affect the external shape of the cable pass-through coupling surface 25 or the third face 21.

[0113] Consequently, in the operating position, the cable passage device 1 advantageously allows the cable glands 16 to be oriented, with each of the first two faces 17, both towards the mounting face 30 and towards the visible face 31, and with each of the second two faces 19, both towards the upper side 7 and towards the lower side 5. In the prior art, since installers can easily miscalculate the top-down and front-back orientation of the cable glands, but they 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 orientation of the installation, 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 optimal sealing provided in all four intended orientations.

[0114] According to one embodiment (Figures 16, 17), the grooves 26 comprise:

[0115] - two external grooves 26', each adjacent to an external edge 32 formed between the third side 21 and the first side 17,

[0116] - a central groove 26" having a width (in the first local direction 18), greater, preferably greater than twice, the width (in the first local direction 18) of the outer groove 26'.

[0117] The ribs 27 comprise:

[0118] - two separating ribs 27' extending respectively between one of the grooves outer 26' and central groove 26",

[0119] - two 27" edge ribs forming the outer edges 32.

[0120] The outer grooves 26' have a rectangular cross-section. The central groove 26" has a flat bottom and two lateral surfaces curved in an arc of a circle.

[0121] 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'.

[0122] 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 penetrate locally into the elastomeric material of the cable gland 16, defining a certain sealing line.

[0123] The through channel 23 has a constant cross-sectional shape, for example circular cylindrical and / or oval and / or flattened, optionally with the sole exception of one or more circumferential ribs 33 projecting radially towards the interior of the through channel 23 to improve sealing and anti-unscrewing engagement between the cable gland 16 and the cable or the conduit enclosed by the latter.

[0124] The first two faces 17 are preferably parallel to each other and possibly smooth (except for any raised markings and the through channel 23). Advantageously, the first faces 17, and possibly the entire cable gland 16, have a symmetrical shape with respect to the first local plane of symmetry 29.

[0125] More advantageously, the second faces 19, or even the whole of the cable pass-through 16, have a symmetrical shape with respect to a second local plane of symmetry 34, orthogonal to the second local direction 20.

[0126] This allows a plurality of cable glands 16 to be stacked in the receiving housings 11.

[0127] The cable glands 16 are made of elastomeric material, preferably thermoplastic elastomer (TPE).

[0128] The cable glands 16 may include a plurality of through channels 23 formed in the same cable gland 16. The through channel or channels 23 of the cable gland 16 may be formed in a central position with respect to an outer contour of the cable gland 16, or in an eccentric position with respect to an outer contour of the cable gland 16.

[0129] "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 plug positions not used for the passage of cables.

[0130] Detailed description of reception accommodations 11

[0131] 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 uprights 8 and intermediate uprights 10 (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.

[0132] According to one embodiment ([Fig.8]), the ribs 36 comprise:

[0133] - two external ribs 36', one closer to the mounting face 30 and the other closer to the visible face 31,

[0134] - a 36" central rib having a greater width, preferably greater than double the width of the outer rib 36'.

[0135] The grooves 35 include:

[0136] - two separating grooves 35' extending respectively between one of the ribs exterior 36' and central rib 36",

[0137] - only in the side posts 8 and possibly in one post intermediate connecting 10' (which will be described below), plus two 35" delimiting grooves delimiting the mating surface of the uprights 28 on the face of assembly 30 and on the visible face 31. Preferably, the 35" delimiting grooves are not present in the remaining 10 intermediate uprights.

[0138] The outer ribs 36' have a triangular, or canine, cross-section, defining the apical ridge above. More advantageously, they form two intermediate flat surfaces 37, set back from the apical edge 38 and extending on either side of it. The central rib 36" has a flat apex and two lateral surfaces curved in an arc.

[0139] The separating grooves 35' all form a flattened rib apex, preferably planar. The delimiting grooves 35", when present, have a substantially angular profile, that is to say they define an external corner edge or an angular recess of the corner edge of the side post 8 or, possibly, of the intermediate connecting post 10'.

[0140] Advantageously, the delimitation 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 elastomer material of the first face 17 of the cable gland 16 directly towards the application wall 2.

[0141] Advantageously, the boundary grooves 35" on the visible face 31 have a rectangular U-shaped form, open only towards one of the lateral sides 9, so as to form a closing edge 39 which comes into contact (in a watertight manner) with the first face 17 of the cable passage 16 on the visible face 31.

[0142] The closing edge 39 on the visible face 31 extends along the side uprights 8, along at least one intermediate connecting upright 10' (if provided), as well as along the base cross member 4 and along the top cross member 6 forming a watertight protection all around the receiving housings 11.

[0143] 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 the intermediate connecting upright 10', are at least partially or totally 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]).

[0144] The vertical coupling surfaces 28, preferably the entire frame 3, are made of thermoplastic material, for example glass fiber-reinforced polyamide, having a hardness greater than that of the elastomer material of the cable glands 16.

[0145] According to one embodiment, the vertical mating surfaces 28, without the boundary grooves 35" and without the closing edge 39, are symmetrical with respect to the plane of the frame 13. Conversely, the entire set of receiving housings 11, including the boundary grooves 35" and the closing edge 39, are not symmetrical with respect to the plane of frame 13, due to the two different functions of interaction with the cable passages 16 on the mounting face 30 and on the visible face 31 ([Fig. 19]).
