Description

Technical Field

[0001] This utility model relates to a cable entry device that can be installed on the wall of, for example, an electrical cabinet at a channel opening. Power cables, signal cables, or fluid pipes must be guided through the channel opening in an orderly and stable manner to ensure the desired level of sealing and to avoid the risk of unwanted damage and movement of the cables themselves. Background Technology

[0002] A cable entry device is known from EP1236256 A1, which has two frame parts that can be connected to each other in a closed position to form a rectangular frame and can be separated from each other in an open configuration. The two frame parts define a plurality of through seats for receiving one or more resilient cable loops applied around a cable or conduit, wherein...

[0003] - When both frame parts are in the open position, cable loops and the cables or pipes they surround can be positioned in or removed from the through-hole.

[0004] - When the two frame parts are in the closed position, the cable loops are in close contact with each other and abut against the frame parts, forming a substantially waterproof plate together with the frame parts, through which the cable surrounded by the cable loops passes.

[0005] It is also known to obtain a first U-shaped or comb-shaped frame component with a base beam from which two lateral posts protrude, and possibly one or more additional intermediate posts, wherein through seats are defined between two adjacent posts, thus allowing cable loops to be temporarily inserted and positioned in the first frame component.

[0006] It is also known that a beam-shaped second frame component is provided, which can be connected to the initial free ends of the lateral and intermediate columns of the first frame component to close the through seat and tighten the cable loop in the closed position.

[0007] It is also known that a second U-shaped or comb-shaped frame component is configured, which is substantially mirror-shaped relative to the first frame component, and can be connected to the first frame component to close the through seat and tighten the cable loop in the closed position.

[0008] It is also known to obtain cable loops with outer surfaces, grooves, or shaped ribs, and to obtain through seats for frame parts with grooved or ribbed inner arc surfaces, so as to increase the local contact pressure between the through seat and the cable loop when the cable entry device is in the closed position, and thus seal.

[0009] Secure the cable entry device to the wall of the application by tightening the fastening screws (e.g., four) and inserting appropriate washers between the cable entry device and the wall itself.

[0010] To allow fastening screws to be screwed onto the application wall (which is typically made of a thin sheet or a material unsuitable for screwing), it is known to apply suitable bushings or internally threaded rivets to the application wall.

[0011] However, existing cable entry devices have several drawbacks.

[0012] It is inconvenient to properly position the additional washer (which is initially separate from the frame of the cable entry device) between the cable entry device and the wall.

[0013] Improper positioning of the additional washer and / or uneven or excessive tightening of the fastening screws can damage the additional washer and compromise the seal of the installed cable entry device.

[0014] The flatness tolerance of the frame components made of synthetic materials by molding increases the flatness tolerance of the application wall, and is not always fully compensated by the elastic deformation of the additional gasket between the cable entry device and the application wall.

[0015] To date, the continuity of the sealing barrier cannot be ensured between the interface area between the cable loop and the through seat, the sealing area between different frame parts, and the sealing area between the frame parts and the wall.

[0016] In the prior art, the gasket between the cable entry device and the wall has the same gray or black color as the frame parts. The lack of color contrast between the gasket and the frame parts obscures the individual observation of the gasket relative to the frame parts, making it difficult to discern their correct positioning and shape, interruptions in gasket continuity (damage, cutting, twisting), or gasket placement. This difficulty arises with individual gaskets (e.g., adhesive gaskets) and overmolded gaskets (applicant's internal knowledge).

[0017] Another drawback of existing technology is that, in order to allow the fastening screws to be tightened onto the application wall, the bushing or internally threaded rivet must have a rivet head or flange protruding from the application wall into the interface of the cable entry device, thus hindering the sealing requirements in that area. Currently, cable entry device assemblers attempt to compensate for the thickness of the flange or rivet head by inserting another sealing or rubber layer with a thickness of approximately 1 mm to 2 mm, or by tightening the fastening screws (e.g., pressing the rivet head into the plastic material of the cable entry device frame). Neither of these measures can guarantee the intended impermeability.

[0018] Finally, when assembling and wall-mounting cable entry devices, the additional washers and fastening screws can easily detach from the frame parts and fall off or get lost. Utility Model Content

[0019] Therefore, the purpose of this invention is to provide an improved cable entry device that eliminates at least some of the disadvantages of the prior art.

[0020] A particular objective of this invention is to provide a cable entry device that features, for example, simplified assembly and installation, and prevents the use of cable entry devices with gaskets that are improperly positioned, damaged, or have discontinuous operation.

[0056] Description of cable entry device 1

[0057] Referring to the accompanying drawings, the multi-cable entry device 1 (i.e., adapted to obtain a sealed passage for one or more cables or conduits (not shown) passing through the application wall 2) includes:

[0058] - Frame (3), which is formed to face the mounting side (30) of the application wall (2) and the visible side (31) opposite to the mounting side (30).

[0059] - One or more receivers (11), defined by the frame (3), and passing through in the cable channel direction (12) transverse to the frame plane (13) of the frame (3),

[0060] - One or more cable loops (16), made of elastic material, in the operating position ( Figure 4 It can be positioned in the receiver (11).

[0061] - A mounting washer (46), made of an elastic material, extends on the mounting side (30) of the frame (3) and protrudes from the frame (3) on the mounting side (30), the mounting washer (46) having a mounting washer color,

[0062] According to one aspect of the present invention, the frame (3) has a frame color on the mounting side (30) that is different from the color of the mounting gasket.

[0063] Due to the color contrast between the gasket and the frame or frame parts, the gasket can be observed relative to the frame parts, their mutual positioning, and any abnormalities in shape, position, or continuity (damage, cutting, twisting).

[0064] According to one embodiment, the color of the mounting washer (46) is different from the frame color of the frame surface of the frame (3) that is directly adjacent to and near the mounting washer (46) throughout the entire extension of the mounting washer (46).

[0065] This helps the user identify (without needing to perform an in-depth visual and tactile inspection along the mounting gasket 46) any breaks or deformations in the continuity of the mounting gasket 46, such as stretching, denting, or poor filling.

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

[0067] If there is a clear line against a dark background, any possible interruption in the continuity will be more noticeable to the human eye.

[0068] According to a preferred embodiment, the mounting gasket is blue, such as light blue or blue, while the frame is preferably gray or black.

[0069] In the field of mechanical assembly, typical impurities include metal shavings, dusty boards mixed with lubricating grease, or leftover self-adhesive labels. These impurities are more visible against backgrounds with light blue and blue shading than against other background colors (e.g., red, orange, gray, black), for example, in the light reflection range of approximately 435 to 500 nanometers.

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

[0071] More specifically, advantageously:

[0072] - In the first forming step, the frame (3) is formed by injection molding, and during this first forming step, a cavity system is formed in the frame (3) itself on the extension of the mounting gasket (46).

[0073] -The mounting gasket (46) is then formed by injection molding in the second forming step, during which the hardened cavity system of the frame (3) is used as the core for the injection molding of the mounting gasket (46).

[0074] During the production process, the color difference between the mounting gasket (46) and the frame (3) has allowed for visual inspection of the continuity and integrity of the mounting gasket (46).

[0075] Detailed description of Frame 3

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

[0077] Lateral posts 8 and intermediate posts 10 (if provided) define a plurality of receivers 11 that pass through the cable channel direction 12 and are transverse to or orthogonal to the frame plane 13 of the frame 3.

[0078] Frame 3 is divided into at least a first frame part 14 and a second frame part 15, which are in the closed position ( Figure 1 They can be connected to each other; this is the configuration for using cable entry device 1, and in the open position ( Figure 14 They can be separated from each other, which allows the cable loop 16 to be inserted into the receiver 11.

[0079] According to one embodiment, the first frame component 14 forms a base beam 4, two lateral columns 8, and one or more intermediate columns 10 in a comb-like structure. Figure 5 The second frame component 15 forms the upper beam 6. The first frame component 14 and the second frame component 15 can be connected to each other by means of connecting screws 40, which can be inserted into the connecting holes 49 of the upper beam 6 and the corresponding connecting holes 49' of the side columns 8 (and, if provided, one or more intermediate connecting columns 10'), and can be screwed into connecting nuts 41, for example, to be non-releasable and non-rotatable accommodated or interlocked in the base beam 4 (in the hexagonal base, not shown).

[0080] The free ends (in the open position) of the lateral columns 8 and the intermediate column 10 include connecting protrusions 42, which (in the closed position) are inserted into corresponding connecting recesses 43 in the upper beam 6. Figure 3 , Figure 4 (to further stabilize and align the first frame part 14 and the second frame part 15).

[0081] Frame 3 (preferably only the first comb-shaped frame part 14) forms a plurality of (e.g., four) mounting through holes 44 extending in the cable channel direction 12 to receive mounting screws 45 that can be screwed into the application wall 2. Figure 14 ).

[0082] The mounting gasket (46) made of elastic material is also formed as follows:

[0083] - A first mounting washer part (46'), which is overmolded onto the first frame part (14) and protrudes from the frame (3) on the mounting side (30), and

[0084] - A second mounting washer part (46'') is overmolded on the second frame part (15) and protrudes from the frame (3) on the mounting side (30).

[0085] Because the mounting washer 46 is overmolded onto the frame 3, the need for a separate washer and the risk of incorrect positioning of the washer itself are eliminated.

[0086] Mounting washers 46 surround all receiving seats 11, particularly along the base beam 4, side columns 8 and upper beam 6, and also around all mounting holes 44, preferably extending continuously in a circular pattern or in segments (connected together by any means of sealing contact) around each mounting hole 44.

[0087] Preferably, the color of the mounting washer is different from the frame color of the frame surface of the frame (3) directly adjacent to and adjacent to the mounting washer (46) on the entire extension of the first mounting washer part (46') and the entire extension of the second mounting washer part (46'').

[0088] To compensate for factory tolerances of frame 3, mounting washers 46 protrude from the surface of frame 3, with a 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, to prevent the mounting washer 46 from being squeezed due to over-tightening of the mounting screw 45, the frame 3 forms a plurality of abutment heights 47 on the mounting side 30 adjacent to the mounting washer 46 (preferably at or near the mounting hole 44). Figure 9 Compared to existing technologies, the adjacency height 47 allows for the use of a higher mounting washer 46. Height 47 can be positioned externally relative to the mounting hole 44 (in...). Figure 9 The height 47 is indicated by reference numeral 47 in the attached drawing to prevent undesirable buckling of the frame 3 in response to the tightening of the mounting screws 45. The height 47 may also be formed, or simply by, for example, the protruding edge of the mounting hole 44, as... Figure 7 As shown.

[0090] The cable entry device (1) or frame 3 further includes an upper beam washer 48 made of elastic material, which is overmolded on the frame 3, particularly only on the second frame part 15, and protrudes from the upper beam 6 toward the lower side 5 of the frame 3 into the receiving seat 11, thereby sealingly engaging the cable loop 16 adjacent to the upper beam 6.

[0091] Because the upper beam washer 48 is overmolded on the frame 3, the need for a separate washer and the risk of incorrect positioning of the washer itself are eliminated.

[0092] Advantageously, the upper beam washer (48) has the color of the beam washer.

[0093] Among them, the frame color of the frame (3) at the upper beam (6) is different from the color of the beam washer.

[0094] According to one embodiment, the color of the beam washer is lighter than the color of the frame at the upper beam (6).

[0095] Advantageously, the beam washer is light blue or blue, while the frame of the upper beam (6) is preferably gray or black.

[0096] According to a preferred embodiment, the upper beam washer 48, together with a portion of the mounting washer 46 extending into the upper beam 6, is formed as a single piece and has material continuity. Figure 3 In this case, advantageously, the beam washer color can be the same as the mounting washer color.

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

[0098] Advantageously, the base beam 4 may not have an elastic washer for engaging the cable loop 16, and can serve as a seal by directly engaging, for example, one or more ribs of the base beam 4 and the adjacent cable loop 16.

[0099] According to one embodiment ( Figure 6 , Figure 7 , Figure 15 The mounting hole 44 forms a recess 50 (or an enlarged outer portion) on the mounting side 30, which is wider than the rest of the mounting hole 44 and is adapted to receive the internal threaded rivet or the rivet head or bushing flange of the bushing 52 of the application wall 2. This avoids the need for an additional gasket "isolation" layer between the cable entry device 1 and the application wall 2.

[0100] According to one embodiment, the mounting hole 44 forms an interference protrusion 51 that extends radially inward and is configured to achieve interference engagement with the mounting screw 45 as a measure to prevent the mounting screw from falling off.

[0101] According to one embodiment, the first frame part 14 and the second frame part 15 can be connected in the closed position by means of a snap-fit ​​(e.g., with a ratchet). Figure 20 They are (pre) connected to each other to obtain a temporary connection, in preparation for final tightening with connecting screws.

[0102] Detailed description of cable swivel 16

[0103] According to one embodiment, one or more cable loops 16 made of a resilient material and positionable in an operational position within the receiver 11 include:

[0104] - Two opposing first (axial) surfaces 17, which face the first local direction 18 of the cable loop 16 ( Figure 16 The partial direction 18 shown), and the direction facing the cable channel 12 in the operating position (as shown) Figure 1 , Figure 4 The cable channel direction shown is 12).

[0105] - Two opposing (top-bottom) second surfaces 19, facing the second partial direction 20 of the cable loop 16, and in the operating position intended to face the lower side 5 and upper side 7 of the frame 3 respectively.

[0106] - Two opposing (lateral) third surfaces 21, facing the third local direction 22 of the cable loop 16, and respectively facing the two lateral sides 9 of the frame 3 in the operating position.

[0107] - Through passage 23, which extends in the first local direction 18 and leads to the two first surfaces 17, to receive and enclose cables or pipes.

[0108] - Separation cut 24, which extends unidirectionally from through passage 23 to only one of the third faces 21 and is spaced apart from the two second faces 19 to allow cables or pipes to be inserted laterally into through passage 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 direction relative to the other two directions).

[0110] Both second surfaces 19 of the cable loop 16 are planar, parallel to each other, and preferably smooth (the term smooth should be understood as smooth to a certain extent to ensure a seal at the contact interface of the two second surfaces 19, for example, there may also be local or very low surface textures (e.g., a cover layer for identification or alphanumeric codes). Alternatively, the second surfaces 19 of the cable loop 16 may be knurled.

[0111] The two third surfaces 21 of the cable loop 16 each form a loop engagement surface 25 having a plurality of linear grooves 26 and ribs 27 parallel to each other and parallel to the second local direction 20. The loop engagement surface 25 is intended to engage in the operating position with the corresponding post engagement surface 28 of one of the lateral post 8 and the intermediate post 10 (if provided).

[0112] The cable ring connecting surface 25 (preferably the entire third surface 21) is symmetrical with respect to the first local symmetry plane 29 perpendicular to the first local direction 18.

[0113] In the operating position, each cable loop 16 can thus be accommodated in a receiver 11 in four different orientations, with all loops having the same engagement shape and geometric connection between the loop connection surface 25 and the post connection surface 28. Preferably, all loops have the same engagement shape and geometric connection between the entire third surface 21 and the receiver 11.

[0114] In the operating position, the two cutting surfaces of the separation cut 24 remain in continuous contact with each other without affecting the external shape of the grommet connection surface 25 or the third surface 21.

[0115] Therefore, in the operating position, the cable entry device 1 advantageously allows the cable loop 16 to face the mounting side 30 and the visible side 316 with each of the two first faces 17, and to face the upper side 7 and the lower side 5 with each of the two second faces 19. In the prior art, although assemblers can easily miscalculate the vertical and horizontal orientation of the cable loop, they will not miscalculate the direction of the through passage 23 due to the forced path of the cable. The new construction eliminates any doubt about the mounting orientation, significantly reduces the risk of incorrect positioning of the cable loop 16, speeds up the assembly of the cable entry device 1, and ensures optimal planned sealing in all four orientations.

[0116] According to one embodiment ( Figure 16 , Figure 17A ), trench 26 includes:

[0117] - Two outer grooves 26', each outer groove being adjacent to the outer edge 32 formed between the third surface 21 and the first surface 17.

[0118] - The width of the central groove 26'' (in the first local direction 18) is greater than, preferably greater than twice the width of the outer groove 26' (in the first local direction 18).

[0119] Rib 27 includes:

[0120] - Two separate ribs (27') extend between an outer groove 26' and a central groove 26'', respectively.

[0121] - Two edge ribs 27'' form the outer edge 32.

[0122] The outer groove 26' has a rectangular cross-sectional shape. The central groove 26'' has a flat bottom and two curved lateral surfaces with an arcuate cross-sectional shape.

[0123] Both the separating rib 27' and the edge rib 27'' form flat, preferably planar, rib tips. The edge rib 27'' protrudes beyond the separating rib 27' in a third local direction.

[0124] Advantageously, in the operating position, the central groove 26'' receives the corresponding central rib 36'' of the post connection surface 28 via a form connection, and the outer groove 26' receives the corresponding outer rib 36' of the post connection surface 28 via a form connection and elastic preload. The outer rib 36' preferably has a pointed edge ridge 38 so as to partially sink into the elastic material of the cable loop 16 to define a specific sealing line.

[0125] The through passage 23 has a constant cross-sectional shape, such as cylindrical and / or elliptical and / or flat, with the only exception being one or more circumferential ribs 33 that protrude radially toward the interior of the through passage 23 to improve the sealing and anti-loosening engagement between the cable loop 16 and the cable or conduit surrounded by the cable loop.

[0126] The two first surfaces 17 are preferably parallel to each other and may be smooth (except for possible raised markings and through-paths 23). Advantageously, the first surfaces 17 (may be the entire cable loop 16) have a shape symmetrical with respect to the first local plane of symmetry 29.

[0127] More advantageously, the second face 19 (possibly the entire cable loop 16) has a shape symmetrical with respect to the second local plane of symmetry 34 perpendicular to the second local direction 20.

[0128] This allows multiple cable loops 16 to be stacked in the receiver 11.

[0129] The cable loop 16 is made of an elastic material, preferably a thermoplastic elastomer (TPE).

[0130] The cable loop 16 may include a plurality of through passages 23 formed in the same cable loop 16. At least one through passage 23 of the cable loop 16 may be formed in a central position relative to the outer contour of the cable loop 16, or in an off-center position relative to the outer contour of the cable sleeve 16.

[0131] A “blind” elastic grommets may also be provided, which have the same external shape as the cable grommets 16, but without the through passage 23, and are intended to block locations not used for cable passage.

[0132] Detailed description of receiver 11

[0133] The column connection surface 28 forms a plurality of linear grooves 35 and ribs 36, which are parallel to each other and parallel to the extensions of the lateral columns 8 and the intermediate column 10 (if provided). The column connection surface 28 is designed to engage the corresponding grommet connection surface 25 in the operating position in a form-fit and sealing press contact manner.

[0134] According to one embodiment ( Figure 8 ), ribs 36 include:

[0135] - Two outer ribs 36', one near the mounting side 30 and the other near the visible side 31.

[0136] - The width of the central rib 36'' is greater than, preferably greater than twice the width of the outer rib 36'.

[0137] Trench 35 includes:

[0138] - Two separation grooves 35' extending between one of the outer ribs 36' and the central rib 36'' respectively.

[0139] - Two additional boundary grooves 35'' define the column connection surface 28 on the mounting side 30 and the visible side 31, only in the lateral columns 8 and possibly in the intermediate connecting columns 10' (which will be described below). Preferably, the boundary grooves 35'' are not present in the remaining intermediate columns 10.

[0140] The outer rib 36' has a triangular apex or a pointed cross-sectional shape defining the aforementioned tip edge ridge. More advantageously, the outer rib 36' forms an intermediate surface 37 of two planes that is recessed relative to the tip edge ridge 38 and extends laterally along the tip edge ridge 38. The central rib 36'' has a planar apex and two curved lateral surfaces with an arcuate cross-sectional shape.

[0141] The separation grooves 35' all form flat, preferably planar, rib tops. If present, the boundary grooves 35'' have substantially angled profiles, i.e., they define the outer angled edges or angled recesses of the angular edges of the lateral posts 8 or possibly the intermediate connecting posts 10'.

[0142] Advantageously, the boundary groove 35'' on the mounting side 30 is triangular, facing one of the lateral sides 9 and opening toward the mounting side 30, so as to directly expose (and be able to compress) the elastic material of the first face 17 of the cable loop 16 to the application wall 2.

[0143] Advantageously, the boundary groove 35'' on the visible side 31 has a rectangular U-shaped shape and is open only toward one of the lateral sides 9, thereby forming a closed edge 39 that (sealingly) engages the first face 17 of the cable loop 16 on the visible side 31.

[0144] The closed edge 39 on the visible side 31 extends along the lateral column 8, along at least one intermediate connecting column 10' (if provided), and also along the base beam 4 and the upper beam 6, thereby forming a waterproof protection around the receiving seat 11.

[0145] The intermediate post 10 (which has no boundary groove 35'' and closed edge 39, and whose cross-sectional area and extension in the cable channel direction 12 are smaller than those of the lateral posts 8 and the intermediate connecting post 10' in the cable channel direction 12) is at least partially or completely covered by the edge ribs 27'' of the cable loop 16 in the insertion operating position on the mounting side 30 and the visible side 31. Figure 19 ).

[0146] The column connection surface 28 (preferably the entire frame 3) is made of a thermoplastic material, for example, of polyamide filled with glass fiber, which has a harderness than the elastic material of the cable loop 16.

[0147] According to one embodiment, the post connection surface 28 (excluding the boundary groove 35'' and the closed edge 39) is symmetrical with respect to the frame plane 13. Conversely, the entire receiver 11 (including the boundary groove 35'' and the closed edge 39) is asymmetrical with respect to the frame plane 13 due to two different functions interacting with the cable loop 16 on the mounting side 30 and the visible side 31. Figure 19 ).
