Description

[0001] The invention relates to a cable feedthrough according to the preamble of claim 1, which can guide a cable through an opening in a component, wherein the cable feedthrough comprises a base body that has a channel for the cable and a first region that has an enclosing fixing region. Furthermore, the invention relates to a cable feedthrough kit, a product for a road vehicle that comprises a component with an opening for the cable feedthrough, and a cable feedthrough kit.

[0002] Such a cable entry is known from DE 20 58 148 C3. This document describes a termination for a power cable that has a gland assembly. An insulating sleeve described therein surrounds a core emerging from a housing of the cable termination. With the gland assembly, a seal is pressed so tightly, e.g., by tightening screw nuts, into the gland and simultaneously against the outer surfaces of the insulating sleeve that the sleeve is permanently held in place, while also sealing the outlet opening of the housing to prevent moisture from entering.

[0003] FR 2519814 also describes a gland assembly used in a fiber optic cable entry. In this gland assembly, the fiber optic cable is routed through a nut that secures the cable to the cable entry.

[0004] EP 0 660 482 A1 also discloses a cable bushing having a stuffing box arrangement. In this stuffing box arrangement, a sleeve is inserted between a cable sheath and a cable shield. By tightening a tensioning element, a force is exerted on a seal in the stuffing box arrangement, which in this cable bushing presses the seal against the cable sheath and the wall of a wall component. In the arrangement of EP 0 660 482 A1, the sleeve enables the seal to be sealed even after extended periods of time and under comparatively large pressure differences. This is because the cable sheath is strongly supported internally by the sleeve, so that the radially inward forces exerted by the sealing body cannot push the sheath radially inward and thereby deform the sheath core. In EP 0 660 482 A1, a nut through which the cable is guided is used as the tensioning element.The shielding is held in contact with an inner surface of the clamping element by a pressed-in ring. This creates an electrically conductive connection between the shielding and the cable gland. The cable gland of EP 0660482 A1 also features a clamping sleeve that is welded to the cable gland in a gas-tight manner. The clamping sleeve is clamped or crimped to the cable sheath. This provides strain relief for the cable and also provides a pre-sealing.

[0005] A further cable entry is known from DE 195 23 795 C1. There, the cable entry comprises a clamping sleeve and a crimp sleeve. The crimp sleeve is clamped to the cable with its crimping section, providing secure strain relief. The crimp sleeve, with its reinforced support section, provides a counter-bearing for the clamping sleeve slid over it, which securely clamps the cable shield all the way around and over a large area.

[0006] In one embodiment of DE 195 23 795 C1, the clamping sleeve is screwed to the housing wall of an electrical device by means of a union nut, so that the exposed ends of the wires of the switch cable are strain-relieved. In another embodiment of DE 195 23 795 C1, the clamping sleeve is extended beyond its clamping section and provided with a thread in this area, onto which a retaining nut is screwed, clamping the clamping sleeve to the housing wall.

[0007] In another embodiment of DE 195 23 795 C1, the clamping sleeve is divided into a clamping section and a fastening section. The clamping section is clamped against the support section of the ferrule, whereby the cable shield is clamped tightly. The fastening section has an enlarged inner diameter and is pushed over a tubular section of a housing, e.g., a cable connector, and firmly connected to it by crimping.

[0008] In DE 195 23 795 C1, a cable bushing was created that can be manufactured and installed with little effort and that enables a reliable shielding effect.

[0009] CH 407 277 A describes a particularly tight cable gland which simultaneously provides particularly effective strain relief, is simple in design and inexpensive to manufacture. This document describes a gland made of elastic plastic with an insert which can be pressed into a corresponding opening in the housing. The insert has an outer surface which tapers towards the inside of the housing and, on the inner side, i.e. in the gland opening, projections and at least one slot through which it can be resiliently compressed. In this way, the gland only needs to be pressed into a corresponding opening in the housing with the cable inserted and hooks onto the inside of the housing wall due to the stiff spring effect of a slotted attachment.Another very simple fastening option is the provision of a lateral shoulder to accommodate a pressure screw. In certain cases, the use of a stiffening plate on the top side of the grommet body and the shoulder can be advantageous. To increase the contact pressure of the pressure screw, the underside of the shoulder can be slightly chamfered so that when the pressure screw is tightened, the edge furthest from the bushing opening comes into contact with the housing first. The above-mentioned advantages are achieved in CH 407 277 A by using suitable rigid-elastic materials. When such materials are used, the cable entry is held so firmly that it cannot be removed from the hole in the housing wall under any load that the cable can absorb, while on the other hand the clamping rib holds the cable absolutely securely in the bushing.Instead of ring-shaped clamping ribs, other projections that press into the cable sheath can also be used.

[0010] US 2012 002 45 99 A1 deals with a wiring harness for oil-cooled equipment. According to US 2012 002 45 99 A1, JP 2003-272729 A discloses an oil-cooled motor cable with a connector structure for connecting an oil-cooled motor to an inverter. This oil-cooled motor wiring harness consists of a shielded wire, a flange, a terminal, and a housing. The flange is formed of a conductive material, and a circular tube with an axis parallel to the shielded wire is integrated with the flat plate-shaped flange perpendicular to the axial direction of the shielded wire. The flange has a screw hole and is conductively attached to the shield housing of the oil-cooled motor by a screw. The housing is integrally formed by resin molding so that the front end portion of the shielded wire is enclosed around the entire circumference without any gap.To prevent cracking or peeling of the resin when tightening the screw connecting the cable to a terminal on the engine, US 2012 002 45 99 A1 proposes a wiring harness with the following features: A front end enclosed by the protective casing for connection to a terminal on a body of oil-cooled equipment. A shielded cable that is flexible and has a conductor surrounded by a shielding layer.

[0011] A terminal enclosing a leading end portion of the shielded wire and connected to the conductor and the terminal of the oil-cooled equipment body. A casing enclosing the periphery of the shielded wire at a predetermined distance from the terminal such that the shielded wire is exposed from the terminal, the casing having a flange for fixing the casing to the shield casing. A first oil ingress prevention means is disposed in a space between the shielded wire and the terminal for preventing oil from the shield casing from entering the conductor. An oil leakage prevention means is disposed in a space between the casing and the shield casing for preventing oil from leaking from the shield casing.The connector and the housing with the shielded cable between the connector and the housing are relatively movable.

[0012] Due to the efforts to significantly reduce costs, it is of central importance to make a further technical contribution that can improve a cable penetration alone, alternatively or in combination with known measures.

[0013] The invention is therefore based on the object of providing a high-quality cable feedthrough in a simple manner.

[0014] This object is achieved by a cable bushing having the features of claim 1.

[0015] The object is also achieved by a cable feedthrough set having the features of claim 7.

[0016] In a set according to the invention for the cable feedthrough according to the invention, the set has a base body according to the invention.

[0017] The problem is also solved by a product for a road vehicle having the features according to claim 8.

[0018] A product according to the invention for a road vehicle comprises a component with an opening for a cable feedthrough according to the invention, wherein the component has a local fixing area at the opening for fixing the cable feedthrough to the component.

[0019] Furthermore, the object is achieved by the use of a set according to the invention for fixing a cable according to claim 9 to a component.

[0020] The cable bushing according to the invention advantageously achieves this objective by providing a fixing device with both an enclosing fixing device and a local fixing device. The enclosing or local fixing device advantageously enables simple installation of the cable, while advantageously protecting the cable core. The enclosing and local fixing devices advantageously enable simple production of the cable bushing.

[0021] Thus, advantageous protection of the cable core can be achieved by using the set according to the invention for fixing a cable to a component, the base body with the cable inserted in the channel can be guided into the opening of the component and, after aligning the base body, the cable can be fixed to the component in a relaxed position with the fixing component.

[0022] Another advantage is that the fixing component and the base body can be easily manufactured independently of each other. This also makes the cable entry kit more cost-effective.

[0023] A set according to the invention has the further advantage that the base body can be manufactured in one piece from a plastically deformable material.

[0024] A product according to the invention for a road vehicle also has the further advantage that the product advantageously meets the requirements necessary for a road vehicle so that the product can be exposed to the environmental influences acting on a road vehicle.

[0025] An inventive use of a set according to the invention also has the further advantage that the use of an installation situation of the cable feedthrough on the component can be advantageously adapted.

[0026] Advantageous embodiments of the invention are specified in the dependent claims.

[0027] Thus, an embodiment of the cable feedthrough according to the invention is advantageous in which the local fixing device for fixing the cable to the component has a tab with a hole arranged eccentrically to a longitudinal axis of the channel. This advantageously allows the base body and thus the cable to be fixed to the component by a rotational movement of a fastening means in the hole. Damage to the cable caused by the rotational movement of the fastening means during fixing of the cable is prevented.

[0028] In a further advantageous embodiment of a cable feedthrough according to the invention, the surrounding fixing region is plastically deformable by crimping to fix the cable to the base body. This advantageously protects the cable core. Among other things, the base body can be advantageously fixed to the component using the local fixing device. The cable inserted into the base body can advantageously be connected to electrical connections of a product that has the component. After connecting the core(s) of the cable, the cable and, if applicable, the core(s) can be advantageously aligned and then advantageously fixed to the base body by crimping the surrounding fixing region.

[0029] In a further advantageous embodiment of the cable feedthrough according to the invention, a contact sleeve is arranged on the first region of the base body in the channel. To secure the cable to the base body, the surrounding fixing region, a cable shield, and the contact sleeve can be connected by crimping, and a protective element can be attached over the surrounding fixing region in a force-fitting and / or form-fitting manner. This advantageously protects the cable core.The interaction of the crimped connection between the base body, the shielding, and the contact sleeve, along with the protective element applied over the surrounding fixing area, easily achieves a very good fixing of the cable to the base body. In addition, this interaction achieves a degree of protection that requires dust tightness, complete protection against contact, and protection against water during high-pressure / steam jet cleaning, particularly in road vehicles, for the cable gland and the component. The very good fixing of the cable to the base body advantageously increases the forces required to pull the cable out of the base body. This advantageously protects the cable gland against destruction, and the part of the wire located within the cable gland or a product with the cable gland is more likely to be protected from acting forces.

[0030] In a further advantageous embodiment of the cable feedthrough according to the invention, the cable shielding can be electrically connected to the component via the local fixing device using a fastening means. This advantageously protects the wire from interference signals through a reliable electrically conductive connection.

[0031] The fastening means can advantageously connect the local fixing device to the component in a force-locking manner. This advantageously creates a permanent connection with low electrical contact resistance between the local fixing device and the component.

[0032] In a further advantageous embodiment of a cable feedthrough according to the invention, the base body has a second region for positively securing the base body. Thus, the base body can advantageously be initially secured to the component without any aids, so that the base body can then advantageously be secured to the component in a simple manner using the fixing device, in particular using a fastening means.

[0033] Advantageous embodiments of cable bushings, sets, and products according to the invention for a road vehicle, as well as the use of a set, advantageously result from the combination of some or more of the described features. This can, for example, increase the number of assembly variants when installing the cable to the component. This advantageously improves the installation for various installation situations.

[0034] The above-described properties, features, and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more readily understood in connection with the following description of the embodiments, which are explained in more detail in conjunction with the figures. They show: Fig. 1 an embodiment of a base body, Fig. 2 a cutaway view of an embodiment of a cable bushing, Fig. 3 an embodiment of a product for a road vehicle, Fig. 4 an embodiment of a road vehicle with a product having a cable feedthrough.

[0035] Fig. 1 shows an exemplary embodiment of a base body 1 for a cable feedthrough 10. The base body 1 has a channel 6 with a circular cross-section that is advantageous for a cable 3 with a circular cross-section. The base body advantageously extends from a first end of the base body 1 in a first direction 100 to a second end of the base body 1. Furthermore, the base body 1 has an enclosing fixing region 22 in a first region. The exemplary embodiment of the base body 1 has a cylindrical shape with circular base surfaces for simple production. The cylindrical shape is rotationally symmetrical to an axis parallel to the first direction 100. The base body 1 has a recess 13 for fixing a protective element 25, which can engage positively in the recess 13. The recess 13 is adjacent to the enclosing fixing region 22 in the first direction 100.In the first direction 100, the base body 1 has a circumferential fixing groove 19 adjacent to the recess 13. It also has, in the first direction 100, a circumferential groove 121 for an O-ring adjacent to the circumferential fixing groove 19. At the second end of the base body 1, the base body 1 has a second region 12 for positively fixing to a component 5. The second region 12 ends in the first direction 100 at the second end of the base body 1 with a region 122 having a smaller cross-section than the cross-section of the base body 1 at the first region. The base surfaces at the first and second ends of the base body 1 each have an opening of the channel 6 for the cable 3 for easy production.

[0036] Fig. 2 shows a cutaway view of an embodiment of a cable feedthrough 10 that can guide a cable 3 through an opening 4 of a component 5. The cable feedthrough 10 comprises the base body 1, which has the channel 6 for a cable 3 and has the enclosing fixing region 22 on the first region of the base body 1. The cable feedthrough 10 comprises a fixing device 2 for fixing the cable 33 to the base body 1 and to a component 5, wherein the fixing device 2 has an enclosing fixing device 21 and a local fixing device 20. The enclosing fixing device 21 has the enclosing fixing region 22. The fixing device 21 encloses the channel 6 in the first region of the base body 1 to protect a wire 7 of the cable 3. The enclosing fixing region 22 for fixing the cable 3 to the base body 1 is plastically deformable.The enclosing fixing region 22 for fixing the cable 3 to the base body 1 is advantageously plastically deformed by crimping after installation, in particular fixing of the cable to the base body 1.

[0037] To fix the cable 3, the sheath 31 of the cable 3 is removed at a first end of the cable 3 and advantageously inserted into a contact sleeve 24 in the first direction 100 so far that the first end of the cable 3 with the shielding 32 protrudes from the contact sleeve 24 and the cable 3 has the sheath 31 in the contact sleeve. The sheath 31 is advantageously directly adjacent to an inner wall 17 of the contact sleeve 24. The shielding 32 comprises a wire mesh. One end of the shielding 32 at the first end of the cable 3 is slipped over the contact sleeve 24 and runs along an outer wall of the contact sleeve 24. In this state, the cable 3 can be inserted into the base body 1 with the contact sleeve 24. To simplify installation of the cable 3 with the contact sleeve 24 in the base body 1, the base body can advantageously have a stop 8. The cable 3 is inserted with the contact sleeve 24 into the base body 1 up to the stop 8.For fixing the cable 3 to the component 5, the local fixing device 20 has a tab 23 with a hole 18 arranged eccentrically to a longitudinal axis 71 of the channel 6. For fixing the cable 3 to the component 5, the local fixing device 20 has a fixing component 233 that can be connected to the base body 1.

[0038] The local fixing device 20 advantageously comprises the fixing component 231 with the tab 23, a fastening means 40, and the circumferential fixing groove 19. The fastening means 40 is advantageously a screw. The fastening means 40 can thus form a precisely positioned and extremely strong force-fitting connection with the component 5. The fixing device 20 can, through the circumferential fixing groove 19 of the base body 1, exert a desired fixing of the cable 3 to the component 5 via the fastening means 40. After the cable 3 has been fixed to the component 5, the fixing component 231 is advantageously connected to the base body 1. The cable feedthrough 10 has an O-ring 70 on the base body 1 in the circumferential groove 121. This achieves improved sealing of the cable feedthrough 10 in the opening 4 of the component 5.This advantageously makes it easier to achieve a degree of protection that requires dust tightness, complete protection against contact and protection against water during high-pressure / steam jet cleaning, especially in road vehicles.

[0039] To fix the cable 3 to the base body 1, the surrounding fixing area 22 can be plastically deformed by crimping.

[0040] The contact sleeve 24 is arranged in the first region of the base body 1 in the channel 6. To fix the cable 3 to the base body 1, the enclosing fixing region 22, the shielding 32 of the cable 3, and the contact sleeve 24 can be connected by crimping, and a protective element 25 can be attached over the enclosing fixing region 22 in a force-fitting and form-fitting manner. After the cable 3 has been fixed to the base body 1, the enclosing fixing region 22, the shielding 32 of the cable 3, and the contact sleeve 24 are advantageously connected by crimping, and a protective element 25 is attached over the enclosing fixing region 22 in a force-fitting and form-fitting manner.

[0041] An embodiment of a cable feedthrough set 10 comprises the base body 1 and the contact sleeve 24. In the embodiment of the Fig. 2, a cable feedthrough set 10 comprises the base body 1, the fixing component 231 which can be connected to the base body 1, and the contact sleeve 24. This allows the individual elements of the set to be manufactured advantageously in a simple manner using cost-effective manufacturing processes. The base body 1 is a turned part, i.e. it can advantageously be manufactured from a metallic material on a lathe. The fixing component 231 is a stamped part, i.e. it can advantageously be manufactured from sheet metal using a stamping device. So that the protective element 25 can be pushed onto the cable 3 at the right time, the cable feedthrough set 10 can advantageously additionally comprise the protective element 25. If the cable feedthrough set 10 advantageously comprises all the parts necessary for the exemplary embodiment of the cable feedthrough 10, the cable feedthrough 10 can advantageously be assembled in a simple manner.For this purpose, the cable entry set 10 can comprise the base body 1, the contact sleeve 24, the protective element 25, the fixing component 231, the fastening means 40 and the O-ring 70.

[0042] Using the set to secure a cable 3 to the component 5 also has the advantage that numerous mounting variants allow for easy installation of the cable 3 and the cable bushing 10 in a variety of ways. The mounting variant for installing the cable 3 and the cable bushing 10 can be advantageously selected for easy installation in an installation situation.

[0043] In a first assembly variant, the cable 3 can be fixed to the base body 1. For this purpose, the enclosing fixing area 22, the shielding 32, and the contact sleeve 24 are connected by crimping. As a result, the enclosing fixing area 22 is plastically deformed during crimping. The plastic deformation of the enclosing fixing area 22 is applied symmetrically about the first direction 100. For this purpose, the circular cross-section of the enclosing fixing area 22 can be plastically deformed in an ideal manner into a hexagon with a basic symmetrical shape. The deformation into a symmetrical hexagonal basic shape is carried out by a crimping tool and, depending on the design of the crimping process, can ideally produce a symmetrical hexagonal basic shape. After the cable 3 has been fixed to the base body 1, the base body 1 can be inserted into the opening 4. Wires 7 of the cable 3 can now be led to electrical connections 51 of a product 50.The product 50 has a border that includes the component 5. The component 5 thus divides a space into two areas, with the enclosing fixing area 22 being present in one area and the electrical connections 51 of the product 50 being present in another area. The wires 7 and the cable 3 can be aligned relative to the electrical connections 51 by rotating the base body 1 in the opening 4, so that the cable 3 and the wires 7 can be connected to the electrical connections 51 in a relaxed position. In particular, care can be taken to ensure that the wires 7 and the cable 3 are not twisted. This would result in increased mechanical and / or electrical stress on the cable 3. The base body 1 can then be fixed to the component 5 using the local fixing device 20.For this purpose, the fixing component 231 can advantageously be rotated in the circumferential fixing groove 19, so that the fastening means 40 can be fixed through the hole 18 into a blind hole 53 already present on the component 5 by a rotating movement of the fastening means 40. The blind hole 53 has a thread for this purpose.

[0044] In a second advantageous assembly variant, the base body 1 can be inserted with an O-ring in the circumferential groove 121 with the second end of the base body 1 into the opening 4. The second area 122 of the base body 1 advantageously enables the base body 1 to be inserted into the opening 4. The base body 1 has the second area 12 for positively fixing it to the component 5. The base body 1 is in the embodiment of the cable feedthrough 10 according to the Fig. 2 is held in the opening 4 by the compressed O-ring 70 and the dimensionally stable second region 12, which extends on both sides of the O-ring 70 along the first direction 100. Thus, the wires 7 and the cable 3 can be aligned by turning and pulling the cable and connected to the electrical terminals 51. Likewise, the base body 1 can be advantageously used by turning to align the cable or wires or to align the hole 18 relative to the blind hole 53. Subsequently, the cable feedthrough 10 can be fixed to the component 5 by the local fixing device 20. This is done in the embodiment of the Fig. 2, as already described in various ways, by tightening the fastener 40. Then, if necessary, the cable 3 can be aligned again. Finally, the cable 3 is fixed to the base body 1. This sub-step was already described in detail for the first assembly variant.

[0045] In an advantageous third assembly variant, the base body 1 can be inserted into the opening 4. The cable 3 can then be inserted into the cable bushing 10 and guided to the electrical connections 51 with the wires 7. The base body 1 can then be fixed to the component 5 using the local fixing device 20. This is done in the embodiment of the Fig. 2, as already described in various ways, by tightening the fastening means 40. Cable 3 and the wires 7 can now be aligned accordingly. Finally, the cable 3 can now be easily fixed to the base body 1 using the enclosing fixing device 21. This sub-step was already described in detail for the first assembly variant.

[0046] After fixing the cable 3 to the base body 1 and to the component 5 with the fixing device 2, the protective element 25 can be pulled over the surrounding fixing area 22. In the embodiment according to Fig. 2, the protective element 25 is made of elastic rubber, so that the protective element 25 is elastically expanded when pushed onto the surrounding fixing area 22. The protective element 25 has a circumferential projection 251 at one end in the first direction 100, which holds the protective element 25 in the recess 13 in a form-fitting manner. Due to the elastic properties of the protective element 25, it is also held force-fittingly to the surrounding fixing area 22.

[0047] Fig. 3 shows an embodiment of a product 50 for a road vehicle 60. The product 50 has a component 5 with an opening 4 for a cable feedthrough 10, wherein the component 5 has a local fixing area 52 at the opening 4 for fixing the cable feedthrough 10. For this purpose, in the embodiment of the Fig. 3 similar to that in Fig. 2 near the opening 4 there is a blind hole 53 with a thread.

[0048] In the embodiment of the product 50 according to Fig. 3, the cable 3 and the cable gland 10 are advantageously installed on the product 50.

[0049] The fixing component 231 has a slot 26 that divides the fixing component 231 into two legs. The fixing component 231 is connected to the base body 1 by being pressed onto the base body 1 in a direction perpendicular to the first direction 100. The distance between the two legs of the fixing component 231 is selected at least at one point such that the two legs must be elastically bent when the fixing component 231 is connected to the base body 1. During the connection, a very good electrical contact is achieved between the two legs of the fixing component 231 and the base body 1.

[0050] The shielding 32 of the cable 3 can be electrically conductively connected to the component 5 via the local fixing device 20 by means of the fastening means 40. After the cable 3 has been fixed to the base body 1 and to the component 5, the shielding 32 of the cable 3 is advantageously electrically conductively connected to the component 5 via the local fixing device 20 by means of the fastening means 40. A product comprising the component 5 can advantageously be electrically conductively connected to the component 5. In the embodiments of the Fig. 3, a very good electrical contact between the local fixing device 20 and the base body 1 is advantageously achieved by the two legs of the fixing component 231 and the slot 26.

[0051] The Fig.4 shows an embodiment of a road vehicle 60 with a product 50 having a cable duct 10. The road vehicle 60 has a space 61 exposed to environmental influences, in which the product 50 is arranged. The product 50 has a border that encloses the component 5. A cable 30 electrically connects another product 64 for a road vehicle 60 to the product 50. The other product 64 has an evaluation device. A cable duct 10, which guides the cable 30 through an opening in the component 5, advantageously fixes the cable 30 to the product 50. The road vehicle 60 can move along a road 62 using one or more wheels 63, depending on the individual wishes of its user. Due to the widely varying individual usage options of the user of the road vehicle 60, high demands are placed on a road vehicle in different protection classes.The product 50 with the cable entry 10 achieves a degree of protection that ensures dust tightness, complete protection against contact, and protection against water during high-pressure / steam jet cleaning, particularly in road vehicles. Thus, the product 50 can be advantageously arranged in the space 61 of a road vehicle 60 despite widely varying environmental influences.

[0052] Although the invention has been further defined in detail by the preferred embodiments, it is not limited to the disclosed examples. Other variations may be derived therefrom by those skilled in the art without departing from the scope of the invention.

[0053] For example, it would also be conceivable that the base body and the fixing component are made from one piece, that the protective element consists of a material that shrinks when exposed to heat, or that the sheath of the cable in the contact sleeve is partially not directly adjacent to the inner wall of the contact sleeve, e.g. by the shielding of the cable in the contact sleeve being partially directly adjacent to the inner wall of the contact sleeve, although in these cases not all advantages of the invention need to be achieved.
