Description

The invention relates to a cable sealing arrangement for enclosing a portion of an electric cable, to a box arrangement for at least partially enclosing an electrical connector, and to an assembly comprising a cable and a box arrangement. The invention further relates to a vehicle.BACKGROUNDThere is a demand for efficient and reliable electrical connections in vehicles such as in heavy vehicles. The increasing complexity of modern vehicle systems requires robust and flexible connection solutions that can accommodate varying cable and cable harness diameters while maintaining the reliability of the electrical connections.One area where this challenge is present is a chassis and cab junction zone of a vehicle i.e., a portion of a vehicle where electrical connections between ambient conditions and a protected environment within a cab of the vehicle are made. Here, connectors are used to enable connections between electric cables extending between outside conditions and the protected environment within the cab. A box arrangement, such as a connector box, may be provided for protecting these connections from environmental factors such as water and dust that could compromise their integrity.The need for effective protection is underscored by the harsh conditions often encountered at this junction zone. Outside air may be hot or cold, humid or dry, and / or dust laden while inside the cab, temperatures and humidity are generally more stable and the air is also cleaner. Furthermore, vibrations from sources such as a vehicle engine and road roughness can impact the cable, the cable harness, the electrical connections, and / or the connector box. This puts further demand on the connector box.In response to these challenges, various solutions have been proposed for protecting connectors within connector boxes. Commonly, such solutions involve selection of different connector boxes or different variations of a connector box to accommodate varying diameters of cables and / or cable harnesses depending on the vehicle type or vehicle version being produced.Specifically, in the manufacturing of heavy vehicles, different types and / or versions of vehicles are manufactured one after the other along the same production line. This means that different connector boxes must be provided for each specific diameter of cables and / or cable harnesses, leading to increased complexity, cost, and logistical challenges in manufacturing and supply chain management. Moreover, these solutions often rely on manual adjustments or assembly steps, which can introduce human error and compromise the reliability of electrical connections.EP3907832 discloses a housing part for an electrical connector and a housing assembly. The housing parts comprise at least one cable channel for receiving an electric cable and a flange surface, which is adapted for abutment to a complementary housing part. The housing part further comprises a sealing gasket, which extends along the flange surface, wherein the sealing gasket comprises at least two cable sealing portions that extend across the at least one cable channel, one of the at least two cable sealing portions being spaced apart from another of the at least two cable sealing portions in an axial direction of the at least one cable channel. A separate sealing material is provided and is flexible enough to be compressed into open voids, which may be formed between the cable channel and the cable received therein.SUMMARYIt would be advantageous to accommodate varying cable and / or cable harness diameters while maintaining optimal performance and reliability e.g., in the context of a box arrangement for enclosing an electrical connector. In particular, it would be desirable to provide a sealing against external surfaces of cables and / or cable harnesses of different diameters. To better address one or more of these concerns, one or more of a cable sealing arrangement, a box arrangement, an assembly, and a vehicle having the features defined in one or more of the independent claims is provided.According to an aspect, there is provided a cable sealing arrangement for enclosing a portion of an electric cable. The cable sealing arrangement has a centre axis and comprises a resilient compressible sleeve, an axially split tube including a first tube portion and a second tube portion, and an elongated fastening member. The axially split tube is arranged radially outside at least a portion of the resilient compressible sleeve. The elongated fastening member extends circumferentially around the first tube portion and the resilient compressible sleeve. The elongated fastening member extends at least partially radially inside an inner radial surface of the second tube portion.Since the cable sealing arrangement comprises the resilient compressible sleeve, which is arrangeable around the electric cable, and the elongated fastening member extends circumferentially around the first tube portion and the resilient compressible sleeve - the elongated fastening member is able to be tightened in a manner that causes the resilient compressible sleeve to seal against an external surface of the electric cable, which accordingly, can be within a diameter range. Moreover, since the axially split tube is arranged radially outside at least a portion of the resilient compressible sleeve and the elongated fastening member extends at least partially radially inside the inner radial surface of the second tube portion - the first and second tube portions are arrangeable to abut against each other to form the axially split tube to be arranged radially outside the resilient compressible sleeve.Accordingly, in use of the cable sealing arrangement, at least at the elongated fastening member, the resilient compressible sleeve seals against the cable. Electric cables of different diameters, which include cable harnesses comprising different numbers of conductors / wires, extending through the resilient compressible sleeve will sealed against the resilient compressible sleeve, due to resilient compressible properties of the sleeve, when the elongated fastening member is tightened. Further, the axially split tube seals against the resilient compressible sleeve. Thus, the cable sealing arrangement provides a seal around the electric cable. The cable sealing arrangement together with the cable are then useable e.g., in a suitable box arrangement for leading the cable into the box arrangement in a sealed manner.According to a further aspect, there is provided a box arrangement for at least partially enclosing an electrical connector. The box arrangement comprises a box member and a cable entry pipe. The box member comprises at least a first housing half and a second housing half, the first and second housing halves being arranged in sealing abutment with each other. The cable entry pipe extends in an external direction from the box member. A first portion of the cable entry pipe is arranged at the first housing half and a second portion of the cable entry pipe is arranged at the second housing half. The box arrangement comprises a cable sealing arrangement according to any one of aspects and / or examples discussed herein positioned between the first and second portions of the cable entry pipe. An outer radial surface portion of the axially split tube of the cable sealing arrangement is arranged in sealing abutment with an inner radial surface portion of the cable entry pipe.Since the box arrangement comprises the cable sealing arrangement and the outer radial surface portion of the axially split tube of the cable sealing arrangement is arranged in sealing abutment with the inner radial surface portion of the cable entry pipe - during use of the box arrangement, the cable extends through the cable sealing arrangement into / from the box member of the box arrangement in a sealed manner.Since the cable extends into / from the box arrangement in a sealed manner, an electrical connector of the electric cable can be arranged inside the box member without risk of being subjected to external influence when ambient conditions are harsh.According to a further aspect, there is provided an assembly comprising an electric cable and a box arrangement according to any one of aspects and / or examples discussed herein. The electric cable extends through the cable sealing arrangement into the box member of the box arrangement.As discussed above, since the electric cable extends through the cable sealing arrangement into / from the box member of the box arrangement - the electric cable is led into / from the box arrangement in a sealed manner, which means that an electrical connector of the cable can be arranged inside the box member without risk of being subjected to external influence when ambient conditions are harsh.According to a further aspect, there is provided a vehicle comprising a divider wall arranged between an external environment subjectable to ambient conditions and an internal environment at least partially closed off from the ambient conditions. The vehicle comprises an assembly according to any one of aspects and / or examples discussed herein arranged at the divider wall.Since the vehicle comprises the assembly, which comprises the electric cable and the box arrangement, arranged at the divider wall - a sealed connection for the electric cable leading to / from the external environment is provided at the divider wall and thus, readily available for further connection to / from the internal environment.The vehicles discussed herein provide an internal environment at least partially closed off from the ambient conditions of the vehicle. The internal environment may be provided inside a passenger compartment, inside a cab, and / or inside any other container, compartment, or enclosure of a vehicle.Accordingly, the divider wall may form a wall of a passenger compartment, of a cab, and / or of a container, compartment, or enclosure of a vehicle.According to one specific example the divider wall may form a wall of a cab of a heavy vehicle, such as a truck, such as a heavy truck.The cab of the vehicle is typically a cabin in which a driver of the vehicle is positioned, such as seated, when driving the vehicle. The cab may comprise one or more seats for the driver and codrivers or passengers. Optionally, and depending on the kind of vehicle, the cab may comprise one or more of a bunk bed, a table, storage facilities, etc.In a broader sense, the cab may be any container structure at a front-end portion of a vehicle, the container structure being configured for housing components of the vehicle. Accordingly, a further example of a cab may be a container structure at a front-end portion of a driverless vehicle, wherein the container structure houses one or more of electronic components, sensors, batteries, etc.The herein used term electric cable not only relates to a single electric cable but also to a cable harness. That is, a structured assembly of wires and cables for transmitting electrical power and / or signals. In a cable harness, cables and / or wires are bundled together using tubing, sleeves, straps, and / or other means of fastening.Herein, the electric cable is also referred to simply as the cable.The herein discussed external environment is subjected to ambient conditions. Such ambient conditions prevail externally of the internal environment of the vehicle. Accordingly, such ambient conditions may be external of the vehicle or internally within the vehicle, such as in an engine compartment, in a space underneath a cab of the vehicle, etc.The electric cable is provided with an electrical connector, herein also referred to as a connector, which is to be positioned and / or connected within the box member of the box arrangement. Thus, the electrical connector is protected from the external environment. The electric cable is configured to be connected to a further cable, an internal cable, extending between the box member and the internal environment, such as by connection of the electrical connector to a further electrical connector of the further / internal cable.The box arrangement is provided for at least partially enclosing an electrical connector. As discussed above, the electrical connector is an electrical connector connected to the cable that extends between the external environment and an inside of the box member of the box arrangement. Thus, protected connections between cables that extend between the external environment and the internal environment may be provided by the box arrangement.The box arrangement at least partially enclosing the electrical connector means that the connector is arranged within the box member of the box arrangement. As such the box member is closed vis-å-vis the external environment. However, the box member may be open vis-å-vis the internal environment. Accordingly, the box member may open up towards the internal environment.One or both of the first and second housing halves of the box member may comprise one or more gaskets or similar elements arranged to provide the sealing abutment when the two housing halves abut against each other.The sealing abutment of the first and second housing halves ensure that the inside of the box member is protected from the external environment.The cable entry pipe is connected to the box member and extends in an external direction from the box member. The cable entry pipe is provided for the cable to extend therethrough between the external environment and the inside of the box member.Together, the first and second portions of the cable entry pipe may form the cable entry pipe.Since the cable entry pipe comprises the first and second portions, each arranged at each of the housing halves, during assembly, a cable provided with the cable sealing arrangement can be positioned in the first or second portion of the cable entry pipe before the two housing halves are positioned in sealing abutment with each other. Thus, the cable with its electrical connector is easily installed in the box arrangement to form the herein discussed assembly.Prior to the cable being positioned in the first or second portion of the cable entry pipe, it has been provided with the herein discussed sealing arrangement to ensure that the cable will seal against the cable entry pipe once the two housing halves are positioned in sealing abutment with each other.Thus, the seal between the cable and the box arrangement is provided in the assembly. Namely, as mentioned above, the resilient compressible sleeve of the cable sealing arrangement is brought into contact with the cable and the outer radial surface portion of the axially split tube of the cable sealing arrangement is arranged in sealing abutment with the inner radial surface portion of the cable entry pipe.As mentioned above, the cable sealing arrangement is for enclosing a portion of an electric cable. This means that the cable sealing arrangement is configured to extend circumferentially around a longitudinal portion of the cable. As such, the cable sealing arrangement is configured to provide a seal around the relevant cable. The seal is sufficient to close out conditions of an external environment. Accordingly, when the sealing arrangement is provided in connection with a box arrangement, the sealing arrangement prevents water and / or dust to penetrate it. Mentioned purely as examples, the sealing arrangement may live up to an ingress protection code, such as IP 54 or IP 69.When mounted on a cable, the centre axis of the cable sealing arrangement may be substantially concentrical with a longitudinal centre axis of the cable.The resilient compressible sleeve, herein also referred to as the sleeve, may be made from any suitable material that allows an inner surface portion of the resilient compressible sleeve to be brought into contact with an external surface of the cable by the elongated fastening member. Materials such as foamed rubber materials like polyurethane, thermoplastic elastomers, etc. may be used.A cross-section of the electric cable may be more or less round. In the case of one cable, the cross-section may be substantially circular. In the case of a cable harness, the cross-section may have an irregular circumference, but which may still be approximated by a circle. The term diameter in the context of a diameter of the cable herein, refers to a mean diameter of the cable or to a maximum diameter of the cable.The resilient compressible sleeve enables a sealing against an irregular circumference of a cable harness when the resilient compressible sleeve and the first tube portion are tightened around the relevant cable harness via the elongated fastening member.The axially split tube may be made from an elastic material, such as e.g. rubber, polyurethane, thermoplastic elastomers, etc.An outer diameter of the sleeve may be the same or slightly larger than an inner diameter of the axially split tube. Thus, the sleeve may seal against an inner radial surface of the axially split tube.To facilitate mounting of the resilient compressible sleeve onto a cable, the sleeve may be longitudinally slit. Accordingly, the sleeve may be folded open in order to be placed around the cable.The use of the axially split tube firstly, ensures that the cable sealing arrangement provides a proper seal for a cable that extends through a tube or pipe, such as the cable entry pipe of the box arrangement. Secondly, the axially split tube in conjunction with the elongated fastening member provide for an easy mounting of the cable sealing arrangement onto a cable as well as of mounting the cable in the box arrangement.Mounting of the cable sealing arrangement may include, in sequence, positioning the resilient compressible sleeve around the cable, positioning the first tube portion against the sleeve, tightening the elongated fastening member around the first tube portion and the resilient compressible sleeve, and placing the second tube portion over the elongated fastening member and the sleeve against the first tube portion, to close the axially split tube.Thus assembled, the cable sealing arrangement may be positioned in one half of the cable entry pipe before the two housing portions of the box member of the box arrangement are closed. Thus, the cable may be mounted to extend between an outside and an inside of the box member in a sealed manner.The elongated fastening member may be configured to be tightened around the first tube portion and the resilient compressible sleeve.In its simplest form, the elongated fastening member may comprise a piece of string or a piece of wire.According to some examples, the elongated fastening member may comprise a cable tie. In this manner, personnel may easily utilise a ratchet mechanism of the cable tie to securely tighten the elongated fastening member around the first tube portion and the resilient compressible sleeve with one hand while holding the first tube portion and the resilient compressible sleeve in the other hand.According to some examples, the first and / or second tube portion may be provided with first and second lateral recesses, and the elongated fastening member may extend from a radially outer side of the first tube portion to the inner radial surface of the second tube portion via the first and second lateral recesses. In this manner, it may be ensured that the elongated fastening member extends from the outside of the axially split tube at the first tube portion to inside the axially split tube at the second tube portion in a smooth manner.In this context, the term lateral refers to diametrically opposite sides / edges of the relevant tube portion i.e., where an axial division line between the first and second tube portions extends. Accordingly, the first and second lateral recesses may extend in circumferential directions along the first and / or second tube portion from the respective diametrically opposite sides / edges.According to some examples, the second tube portion may be provided with a through opening, and a portion of the elongated fastening member may be accessible via the through opening of the second tube portion. In this manner, the elongated fastening member may be accessible for control or manipulation from outside the axially split tube. Alternatively, or additionally, any securing arrangement of the elongated fastening member around the first tube portion and the resilient compressible sleeve, such as a securing knot, securing wire twisting, or ratchet mechanism may be positioned in or at the through opening to prevent it from potentially interfering with a sealing between the axially split tube and an inner surface of the cable entry pipe.According to some examples, the axially split tube may be provided with a radial flange arranged at one end of the axially split tube. In this manner, the radial flange may be utilised for positioning the sealing arrangement in a box arrangement, such as for positioning the sealing arrangement in relation to a cable entry pipe. Alternatively or additionally, such a radial flange arranged at one end of the axially split tube may be utilised for sealing against one or more therefor devised surfaces of a box arrangement.According to some examples, a radially outer surface portion of the axially split tube may be provided with a circumferentially extending bead. In this manner, the bead may be utilised for positioning the sealing arrangement in a box arrangement, such as for positioning the sealing arrangement in relation to a cable entry pipe. Alternatively or additionally, such a bead may be utilised for sealing against one or more therefor devised surfaces of a box arrangement.According to some examples of the box arrangement, the cable entry pipe may comprise external threads and the box arrangement may comprise a screw cap provided with internal threads and being configured to be screwed onto the cable entry pipe. In this manner, the first and second pipe portions of the cable entry pipe may be secured to each other by the screw cap. Thus, the cable sealing arrangement, and the cable together with it, may be secured in relation to the cable entry pipe and the box member of the box arrangement.According to some examples, the screw cap may be provided with a through hole, and the through hole of the screw cap may be configured for a portion of the cable sealing arrangement (20) to extend therethrough. In this manner, the cable sealing arrangement, and the cable together with it, may be secured in relation to the cable entry pipe and the box member of the box arrangement. Also, further securing of the cable sealing arrangement to the cable outside the cable entry pipe may be provided since the cable sealing arrangement extends through the through hole of the screw cap.According to some examples, the screw cap may seal against the first and second housing halves and / or against the cable entry pipe. In this manner, a further sealing of the box arrangement may be provided at a portion of the box arrangement where the cable sealing arrangement is utilised for the cable to extend between in- and outsides of the box member.According to some examples of the assembly comprising an electric cable and a box arrangement, the assembly may comprise a tubing extending around the electric cable and around a portion of the axially split tube of the cable sealing arrangement. In this manner, a transition may be provided between the cable sealing arrangement and the bare cable outside the box member.For instance, the tubing may comprise a shrink tube, which may provide an additional sealing between the cable and the cable sealing arrangement.According to some examples, the assembly may comprise an electrical connector being connected to the electric cable inside the box member of the box arrangement. In this manner, the cable may be connected to a further cable, such as an internal cable of a vehicle, inside the box member.According to some examples of the vehicle, the divider wall may be provided with a through opening, the box member of the box arrangement may be arranged in sealing abutment with the divider wall to close off the through opening of the divider wall. In this manner, a further cable, such as an internal cable, to / from the internal environment may extend via the through opening into the box member for connection therein to the cable e.g. via electrical connectors. Since the box member may be arranged in sealing abutment with the divider wall, the external environment may be sealed off from the internal environment at the through opening, thus avoiding conditions of the external environment affecting the internal environment.According to some examples of the vehicle, the electric cable of the assembly may be arranged to extend between the external environment and an inside of the box member of the box arrangement, wherein the vehicle may comprise an internal cable, and wherein the internal cable may extend between the internal environment and the inside of the box member. In this manner, the internal cable and the cable of the assembly may connect to each other within the protected space provided inside the box member.According to some examples of the vehicle, the internal cable may extend via the through opening of the divider wall into the box member.According to some examples of the vehicle, the electric cable of the assembly and the internal cable may be connected to each other inside the box member. In this manner, the internal cable and the cable of the assembly may connect to each other within the protected space provided inside the box member.According to some examples of the vehicle, electrical connectors may be provided on the electric cable of the assembly and the internal cable, the electrical connectors may be arranged inside the box member. In this manner, the internal cable and the cable of the assembly may connect to each other within the protected space provided inside the box member.Further features of, and advantages with, the invention will become apparent when studying the appended claims and the following detailed description.BRIEF DESCRIPTION OF THE DRAWINGSVarious aspects and / or examples of the invention, including its particular features and advantages, will be readily understood from the examples discussed in the following detailed description and the accompanying drawings, in which:Fig. 1 schematically illustrates an example of a vehicle,Fig. 2 schematically illustrates an assembly arranged at a divider wall,Figs. 3a and 3b illustrate examples of a cable sealing arrangement,Fig. 4 schematically illustrates a section through a cable sealing arrangement and a cable, andFigs. 5a - 5c illustrate examples of a box arrangement.DETAILED DESCRIPTIONAspects and / or examples of the invention will now be described more fully. Like numbers refer to like elements throughout. Well-known functions or constructions will not necessarily be described in detail for brevity and / or clarity.Fig. 1 schematically illustrates an example of a vehicle 2.The vehicle 2 may be any kind of vehicle configured for land-based propulsion, such as e.g., a bus, a truck, a heavy truck, a car, a heavy equipment vehicle, a construction vehicle or a train. In Fig. 1, the vehicle 2 is illustrated as a heavy load vehicle in the form of a truck.The vehicle 2 comprises a cab 4 arranged on a chassis 6.The vehicle 2 comprises a divider wall 8 arranged between an external environment 10, which is subjected to ambient conditions and an internal environment 12 at least partially closed off from the ambient conditions.Specifically, herein, electric wiring is to extend between the external environment 10 and the internal environment 12. In order to isolate the external and internal environments 10, 12 from each other in connection with electrical wiring extending in this manner, an interface is provided between the external and internal environments 10, 12. The interface comprises one or more of a cable sealing arrangement for enclosing a portion of an electric cable, a box arrangement for enclosing an electrical connector, and an assembly comprising a cable and a box arrangement.The divider wall 8 may be provided in connection with the cab 4, or any other container, compartment, enclosure, or similar at least partially closed structure of the vehicle 2. The internal environment 12 is provided inside such a closed structure and the external environment 10 borders to the relevant closed structure. Moreover, depending on the kind of vehicle, the divider wall 8 may be provided in connection with any other closed structure of the relevant kind of vehicle.In the illustrated example, the divider wall 8 is a wall of the cab 4 of the vehicle 2.Accordingly, illustrated in the example, the internal environment 12 is provided inside the cab 4 and the external environment 10 is outside the cab 4.The vehicle 2 comprises an assembly 14 arranged at the divider wall 8. The vehicle 2 and the assembly 14 are further discussed below with reference to Fig. 2.Fig. 2 schematically illustrates an assembly 14 arranged at a divider wall 8. The assembly 14 may be an assembly 14 as discussed above with reference to Fig. 1.Accordingly, the assembly 14 is arranged at a divider wall 8 of a vehicle 2, such as of any of the above discussed vehicles. In the following, reference is also made to Fig. 1 and the discussion above.The assembly 14 comprises an electric cable 16 and a box arrangement 18.The electric cable 16 extends through a cable sealing arrangement 20 into a box member 22 of the box arrangement 18.The box arrangement 18 and the cable sealing arrangement 20 are further discussed below with reference to Figs. 3a - 5c.The assembly 14 comprises a tubing 24 extending around the electric cable 16 and around a portion of the cable sealing arrangement 20, such as around a portion of an axially split tube of the cable sealing arrangement 20. See further below with reference to Figs. 3a and 3b concerning the axially split tube. In Fig. 2, the tubing 24 is indicated with broken lines.For instance, the tubing 24 comprises a shrink tube, which is shrink-fitted around the cable sealing arrangement 20 and the cable 16 where it transitions into the cable sealing arrangement 20.According to some examples, the assembly 14 comprises an electrical connector 26, such as a male or female portion of an electrical connector assembly, being connected to the electric cable 16 inside the box member 22.In order to show inter alia the electrical connector 26 and cables inside the box member 22, in Fig. 2 a portion of an inside 32 of the box member 22 is shown within a dash-dotted line section.The divider wall 8 of the vehicle 2 is provided with a through opening 28. Via the through opening 28 connections between the external and internal environments 10, 12 may be established. For instance, one or more cables may extend through the through opening 28 of the divider wall 8.However, in order to ensure that the internal environment 12 is not affected by prevailing conditions in the external environment 10, the through opening 28 is sealed off from the external environment 10.Herein, the box member 22 of the box arrangement 18 is arranged in sealing abutment with the divider wall 8 to close off the through opening 28. Optionally, a gasket 30 may extend around the through opening 28 between the box member 22 and the divider wall 8.A cable 34 extending via the through opening 28, to / from the internal environment 12, accordingly, will lead to / from the inside 32 the box member 22. Accordingly, each of the assembly 14 and the box arrangement 18 may be seen to form an interface between the external and internal environments 10, 12.More specifically, in the vehicle 2, the electric cable 16 of the assembly 14 is arranged to extend between the external environment 10 and the inside 32 of the box member 22 of the box arrangement 18. The vehicle 2 comprises an internal cable 34. The internal cable 34 extends between the internal environment 12 and the inside 32 of the box member 22.Thus, a protected electrical connection can be established between the internal environment 12 and the external environment 10, via the inside 32 of the box member 22.Accordingly, the internal cable 34 extends via the through opening 28 of the divider wall 8 into the box member 22.The box member 22 is provided with a through hole for the internal cable 34 to extend to / from the inside 32 of the box member 22, see also Fig. 5a. The through hole provided in the box member 22 for the internal cable 34 is arranged within an area defined by the gasket 30 and / or the through opening 28 of the divider wall 8. No specific sealing of the internal cable 34 as it passes into / from the box member 22 has to be provided since the box member 22 seals against the divider wall 8 and the cable sealing arrangement 20 seals the inside 32 of the box member 22 from the external environment 10.The electric cable 16 of the assembly 14 and the internal cable 34 are connected to each other inside the box member 22. In this manner, the internal cable and the cable of the assembly may connect to each other within the protected space provided inside the box member 22.Electrical connectors 26, 26’ are provided on the electric cable 16 of the assembly 14 and on the internal cable 34. The electrical connectors 26, 26’ are arranged inside the box member 22.For instance, the electrical connectors 26, 26’ may comprise male and female portions via which an electrical connection is established between the cable 16 and the internal cable 34.Figs. 3a and 3b illustrate an example of a cable sealing arrangement 20. Fig. 3a shows an exploded view of the cable sealing arrangement 20. Fig. 3b shows a partially assembled view of the cable sealing arrangement 20.The cable sealing arrangement 20 may be a cable sealing arrangement 20 of a box arrangement 18 as discussed above with reference to Fig. 2 and below with reference to Figs. 5a - 5c. In the following reference is also made to the discussions of Figs. 2, 4, and 5a - 5c.The cable sealing arrangement 20 is configured for enclosing a portion of an electric cable 16, see e.g. Figs. 2, 4 and 5c. The cable sealing arrangement 20 is arranged to seal against the electric cable 16 as well as against a box member 22 of a box arrangement 18.The cable sealing arrangement 20 has a centre axis 36. The centre axis 36 extends in an axial direction of the cable sealing arrangement 20. When enclosing a portion of an electric cable 16, the centre axis 36 of the cable sealing arrangement 20 extends substantially concentrically with a centre axis of the cable 16.The cable sealing arrangement 20 comprises a resilient compressible sleeve 38, an axially split tube 40, and an elongated fastening member 42.The axially split tube 40 comprises a first tube portion 44 and a second tube portion 44’. In an assembled state of the cable sealing arrangement 20, the axially split tube 40 is arranged radially outside at least a portion of the resilient compressible sleeve 38. That is, the axially split tube 40 at least partially encloses the resilient compressible sleeve 38 in a radial direction, seen in relation to the centre axis 36 defining an axial direction.The axially split tube 40 may be made from an elastic material, which enables it to be deformed by the elongated fastening member 42.The resilient compressible sleeve 38 has an inner diameter and the cable 16 has an outer diameter. Since the sleeve 38 is resilient and compressible, the outer diameter of the cable 16 may be smaller than the inner diameter of the sleeve 38. For instance, the outer diameter of the cable 16 may be within a range of 50 - 90 % of the inner diameter of the sleeve 38. Alternatively, for instance, the outer diameter of the cable 16 may be the same as the inner diameter of the sleeve 38. Alternatively, since the sleeve 38 is resilient and compressible, the outer diameter of the cable 16 may be slightly larger than the inner diameter of the sleeve 38. For instance, the outer diameter of the cable 16 may be within a range of 101 - 120 % of the inner diameter of the sleeve 38. A further alternative may be for the outer diameter of the cable 16 to be within a range of 101% of the inner diameter of the sleeve 38 up to 90% of an outer diameter of the sleeve 38.According to some examples, depending on how large a diameter variation of the cables 16 to be mounted is, different kinds of sleeve 38 may be supplied having different inner diameters to accommodate for cables 16 having different diameters. In this context it is neither practical, nor necessary, to provide a separate kind of sleeve for each cable diameter to be used with the cable sealing arrangement 20. Instead, as understood by the above discussion of differences in sleeve 38 inner diameter and cable 16 outer diameter, the present cable sealing arrangement 20 enables the provision of one kind of sleeve 38, or a limited number of different kinds of sleeves 38 of different inner diameters. The present cable sealing arrangement 20 lends itself to seal against cables 16 within a certain diameter range with one kind of sleeve 38 having one inner diameter and to seal against cables 16 within a different diameter range with a different kind of sleeve 38 having a different inner diameter.In an assembled state of the cable sealing arrangement 20, the resilient compressible sleeve 38 is arranged around a portion of the relevant cable 16 to be sealed, as e.g. shown in Figs.4 and 5c. The resilient compressible sleeve 38 may be slit in a longitudinal direction to enable it to be positioned around the cable 16 without having to thread the cable 16 through the resilient compressible sleeve 38.The elongated fastening member 42 extends circumferentially around the first tube portion 44 and the resilient compressible sleeve 38. More specifically, the resilient compressible sleeve 38 is arranged within the first tube portion 44, abutting against an inner radial surface 43 thereof. The elongated fastening member 42 extends around a radially outer surface 45 of the first tube portion 44 and the resilient compressible sleeve 38 arranged within the first tube portion 44.The elongated fastening member 42 is configured to be tightened around the first tube portion 44 and the resilient compressible sleeve 38.In the illustrated example, the elongated fastening member 42 comprises a cable tie, which forms a readily available fastening member 42 useable in the cable sealing arrangement 20.In an assembled state of the cable sealing arrangement 20, the elongated fastening member 42 extends at least partially radially inside an inner radial surface 46 of the second tube portion 44’. Accordingly, the elongated fastening member 42 is arranged at least partially radially inside the second tube portion 44’. Also, the resilient compressible sleeve 38 is arranged within the second tube portion 44’, abutting against an inner radial surface 43’ thereof.Looking at Fig. 3b and the state of the cable sealing arrangement 20 illustrated therein, the elongated fastening member 42 may be tightened 4 further, depending on the diameter of the relevant cable to be sealed. The second tube portion 44’ is to be moved against the resilient compressible sleeve 38 and the first tube portion 44 for the cable sealing arrangement 20 to be in its assembled state. See also Fig. 4 for an example of the assembled state of the cable sealing arrangement 20.In order to facilitate the extension of the elongated fastening member 42 from the outside of the axially split tube 40 at the first tube portion 44 to inside the axially split tube 40 at the second tube portion 44’, the first and / or second tube portion 44, 44’ is provided with first and second lateral recesses 48, 48’. This enables the elongated fastening member 42 to extend from the radially outer surface 45 of the first tube portion 44 to the inner radial surface 46 of the second tube portion 44’ via the first and second lateral recesses 48, 48’.In the shown example both the first and second tube portions 44, 44’ are provided with first and second lateral recesses 48, 48’. The first and second lateral recesses 48, 48’ being lateral means that each of the recesses 48, 48’ is provided at diametrically opposite side edges of the relevant tube portions 44, 44’. The diametrical direction relates to the centre axis 36.In the illustrated example, the second tube portion 44’ is provided with a through opening 50, and a portion of the elongated fastening member 42 is accessible via the through opening 50 of the second tube portion 44’.In addition to any one of the previously discussed advantages related to access, control, and positioning of a portion of the elongated fastening member 42 at the through opening 50 of the second tube portion 44’, the through opening 50 enables tightening of a ratchet mechanism of a cable tie in examples wherein the elongated fastening member 42 is a cable tie. Thus, the elongated fastening member 42 in the form of a cable tie can be tightened around the first tube portion 44 and the resilient compressible sleeve 38 after the second tube portion has been positioned against the first tube portion 44 and the resilient compressible sleeve 38.In the illustrated example, the first tube portion 44 is provided with a groove 47 at its radially outer surface 45. The elongated fastening member 42 is arranged in the groove 47. This may facilitate the positioning of the elongated fastening member 42 around the first tube portion 44. However, in alternative examples, the groove 47 may be omitted.According to some examples, such as in the illustrated example, the axially split tube is provided with a radial flange 52 arranged at one end 54 of the axially split tube 40.The radial flange 52 may be utilised for positioning the cable sealing arrangement 20 in a box arrangement 18, see Figs. 5b and 5c.According to some examples, such as in the illustrated example, a radially outer surface portion 56 of the axially split tube 40 is provided with a circumferentially extending bead 58.The circumferentially extending bead 58 may be utilised for sealing against one or more therefor devised surfaces of a box arrangement 18, see Figs. 5b and 5c.Fig. 4 schematically illustrates a section through a cable sealing arrangement 20 and a cable 16 arranged therein. Fig. 4 shows how sealing is achieved in the present cable sealing arrangement 20 when there is a diameter difference between the cable 16 and part of the cable sealing arrangement 20.The cable 16 shown in Fig. 4 has a smaller diameter than an inner diameter of the resilient compressible sleeve 38 of the cable sealing arrangement 20. Accordingly, Fig. 4 illustrates how a sealing is provided by the cable sealing arrangement 20 against the cable 16 with a smaller diameter than the inner diameter of the resilient compressible sleeve 38.The resilient compressible sleeve 38 and the two tube portions 44, 44’ of the axially split tube 40 enclose a longitudinal portion of the electric cable 16.The elongated fastening member 42 extends circumferentially around the first tube portion 44 and the resilient compressible sleeve 38. The elongated fastening member 42 is tightened to such an extent that the first tube portion 44 and the resilient compressible sleeve 38 are deformed and the resilient compressible sleeve 38 seals against the cable 16.The second tube portion 44’ is positioned against the resilient compressible sleeve 38 with the elongated fastening member 42 arranged between the second tube portion 44’ and the resilient compressible sleeve 38.Thus, as seen in Fig. 4, the resilient compressible sleeve 38 is arranged within the axially split tube 40 to seal against it.According to alternative examples, the axially split tube 40 may be made from a rigid material. In such examples, when tightened, the elongated fastening member 42 may deform the resilient compressible sleeve 38 only, for it to seal against the cable 16.Figs. 5a - 5c illustrate an example of a box arrangement 18. Fig. 5a shows an exploded view of the box arrangement 20. Fig. 5b shows a partial section through the box arrangement 18 in a front view and Fig. 5c shows a section through the box arrangement 18 in a side view.The box arrangement 18 is configured for forming part of an assembly 14 comprising an electric cable 16 and the box arrangement 18 as discussed above with reference to Figs.1 and 2. In the following reference is also made to the discussion of Figs. 1 - 4.The box arrangement 18 is configured for enclosing an electrical connector 26 of a cable 16, as discussed above. In Fig. 5c, the cable 16 is indicated with broken lines.The box arrangement 18 comprises a box member 22, a cable entry pipe 60, and a cable sealing arrangement 20 as discussed herein.The cable entry pipe 60 extends in an external direction from the box member 22 i.e., the cable entry pipe 60 protrudes from the box member 22. The cable sealing arrangement 20 is arranged at least partially in the cable entry pipe 60. As discussed above, the cable sealing arrangement 20 is configured to extend around a portion of the cable 16. The cable sealing arrangement 20 seals against the cable 16 and the cable entry pipe 60 to seal the inside 32 of the box member 22 from an external environment 10 of the box arrangement 18.In the shown example, the cable sealing arrangement 20 extends out of the cable entry pipe 60, see Figs. 5b and 5c.The box member 22 comprises at least a first housing half 62 and a second housing half 62’. The first and second housing halves 62, 62’ are arranged in sealing abutment with each other. For instance, a gasket 64 may be provided with one of the housing halves 62, 62’ for ensuring a secure seal between the first and second housing halves 62, 62’.In Fig. 5a also a portion of a divider wall 8 of a vehicle 2 is shown. Again, the divider wall 8 is provided with a through opening 28 for one or more cables to extend therethrough.As discussed above with reference to Fig. 2, the box member 22 is provided with a through hole 78 for an internal cable 34 to extend to / from an inside 32 of the box member 22.The cable entry pipe 60 comprises two portions 66, 66’.

The second portion 66’ of the cable entry pipe 60 is arranged at the second housing half 62’. The second portion 66’ of the cable entry pipe 60 protrudes from the second housing half 62’.The cable sealing arrangement 20 is positioned between the first and second portions 66, 66’ of the cable entry pipe 60. In order to seal against the cable entry pipe 60, an outer radial surface portion 68 of the axially split tube 40 of the cable sealing arrangement 20 is arranged in sealing abutment with an inner radial surface portion 70 of the cable entry pipe 60, see e.g. Fig. 5b.In the illustrated example, the cable entry pipe 60 comprises external threads 72. The box arrangement 18 comprise a screw cap 74 provided with internal threads 76. The screw cap 74 is configured to be screwed onto the cable entry pipe 60. Accordingly, the internal threads 76 of the screw cap 74 are configured to mate with the external threads 72 of the cable entry pipe 60.Thus, the screw cap 74 is configured to secure the first and second pipe portions 66, 66’ of the cable entry pipe 60 to each other. Moreover, the screw cap 74, threaded onto the cable entry pipe 60, may ensure that the inner radial surface portion 70 of the cable entry pipe 60 is arranged in sealing abutment with the outer radial surface portion 68 of the axially split tube 40.The screw cap 74 is provided with a through hole 80. The through hole 80 of the screw cap 74 is configured for the cable 16 to extend therethrough during use of the box arrangement. Further, a portion of the cable sealing arrangement 20 may extend through the through hole 80 of the screw cap 74. The cable sealing arrangement 20 may be positioned and secured in relation to the cable entry pipe 60 and the box member 22. Accordingly, in use of the box arrangement 18 together with the cable 16, not only the cable 16 but also the cable sealing arrangement 20 may be positioned and secured in relation to the cable entry pipe 60 and the box member 22.In the illustrated example, the screw cap 74 seals against the first and second housing halves 62, 62’ of the box member 22 and against the cable entry pipe 60, see Figs. 5b and 5c. In alternative examples, the screw cap 74 may seal against the first and second housing halves 62, 62’ of the box member 22 or against the cable entry pipe 60.Thus, the screw cap 74 contributes to sealing the box member 22 at the cable entry pipe 60.In the following some of the previously discussed features of the cable sealing arrangement 20 will again be discussed with reference to Figs. 5a - 5c and the box arrangement 18.The axially split tube 40 is provided with a radial flange 52 arranged at one end 54 of the axially split tube 40. The radial flange 52 is utilised for positioning the axially split tube 40 and the cable sealing arrangement 20 in relation to the box member 22.
