Description

TECHNICAL FIELD This invention relates to a connection box for connecting one or more external cables with an internal network of a building. BACKGROUND An important aspect of telecommunication and networking systems is the connection of external lines, for example from telecom providers or Internet Service Providers (ISPs), to the internal network of a building (i.e. a local area network or LAN). The external lines are typically optical fibres or cables; likewise the internal network can include cables or optic fibres. An optical network terminal (ONT) is the interface between the optical fibre external lines and the internal network. For internal networks based on copper, an optical interface is used to convert light from the optical fibre to electrical signals for the internal network and vice versa. In building where there are multiple occupants, for example multiple businesses in a commercial building or multiple tenants in a domestic building, the external lines will need to be connected to multiple internal networks. When connecting cables of the external lines to the connection box, it is conventional to leave some slack in the length of cable leading to the connection box. The slack has several advantages: it ensures the cable isn't pulled too tightly, which could lead to damage and allows for easier maintenance, repairs or future upgrades. The slack is particularly important for optical fibres, which are delicate and can easily be damaged by excessive tension. SUMMARY OF THE INVENTION An aspect of the present invention provides a connection box for installation of one or more cables into a building, the connection box comprising: a housing, comprising a front face, a rear face and at least one side wall between the front and rear faces; an input for receiving a cable originating from outside the building; one or more outputs for receiving one or more cables from within the building; wherein the at least one side wall has an inner surface and an outer surface, wherein the outer surface has a convex curve with a minimum radius of 190mm, the outer surface 1 of the at least one side wall being recessed from the front and rear faces to form a channel for receiving a coil of cable before it enters the input. This channel protects the cable from potential damage, by ensuring it is safely stored and protected from being overly bent. The convex curve may have a minimum radius of 200mm or 250mm or 300mm. The convex curve may have a constant radius of curvature. The convex curve of the side wall is at least 50% of the perimeter, or at least 60% of the perimeter, or at least 70% of the perimeter, or at least 80% of the perimeter, or at least 90% of the perimeter. The channel may have a depth of at least 37mm. This is sufficiently deep to hide the cable from view. The channel may have a depth of at least 40mm, or 45mm or 50mm. The one or more cables may comprise telecommunication cables or electrical cables. The one or more cables may comprise fibre optic cables or metal cables, such as copper cables. For example, the cable originating outside the building may comprise an optic fibre or copper cable and the cables from within the building may comprise optic fibre or copper cables. In one embodiment, the one or more cables originating outside the building comprises fibre optic cables and the one or more cables from within the building comprises copper cables. The cable originating from outside the building may be integrated into a telecommunication or internet service provider (ISP) network. The cables from within the building may be integrated into an internal network or local area network (LAN). The connector box may comprise an optical network terminal (ONT).

DETAILED DESCRIPTION An embodiment of the connection box is shown in Figs 1-32. The connection box 10 has a housing 12, having a front face 14, a rear face 16 and at least one side wall 18. In this embodiment, the at least one side wall 18 comprises a curved wall extending from A to B. The curved wall 18 has inner and outer surfaces, and forms a convex curve on its outer surface. In this embodiment, the curved wall 18 has constant curvature, with a minimum radius of 200mm. The outer surface of the curved wall 18 is recessed from the front and rear faces 14,16 to form a channel defined by the outer surface of the curved wall portion, the front face and the rear face. A cable connection region 20 is located between A and B, and accommodates the inlet 24 for receiving a cable originating from outside the building and multiple outlets 26, each provided with a cable connection for receiving separate cables from within the building. The front face 14 of the housing has an opening 28 which provides access to the interior of the housing. A removable cover 30 provides a closure for this opening. As shown in Fig 14, the interior houses a fibre spice tray holder 54 and splice trays 56, which are held in place by screws for ease of assembly and disassembly. The splice tray holder can hold multiple trays, one for each cable connection at the outlet. In this embodiment, the splice tray holder holds six trays. The splice trays can clip into place onto the splice tray holder, allowing them to be easily added or removed. On the rear face 16 of the housing, a bracket is provided to mount the housing onto a wall or other surface. In use, the housing is mounted to a wall or other surface, via the bracket. A cable originating from outside the building is connected to the housing via the inlet and one or more cables from within the building are connected via the inlets. The cable originating from outside typically enters the building below the connection box. The cable is then directed upwards to the connection box, wound around the channel one or more times and then fed through the inlet into the connection box. The curvature of the channel is selected to protect the cable from breakage by ensuring it is not bent beyond its minimum bend radius, which is particularly important for optic fibres. Furthermore, the curved wall is sufficiently recessed from the front face to hide the coiled cable, thereby creating an aesthetically pleasing finish. Bracket The bracket is shown in more details in Figs 15 and 16. The bracket comprises a housing mount 32 and a cooperating surface mount 34. The housing mount 32 is attached to the rear face 16 of the housing and the surface mount 34 is secured to a wall or other surface on which the housing is to be mounted. Although a wall is described, the surface mount may be mounted to other surfaces such as suitable furniture. The housing mount 32 is provided with first and second parallel elongate elements 36,38, each having a housing facing side, a surface facing side, an upper end, a lower end and inner and outer edges. Each elongate element 36,38 has an upper region 40 toward the upper end, a lower region 42 towards the lower end, and a central region 44 between the upper and lower regions. The upper and lower regions 40,42 have a first diameter, and the central region 44 has a second diameter, which is less than the first diameter. The elongate elements 36,38 are attached to the rear face 16 of the housing at the outer edges. The upper and lower regions 40,42 are spaced from the rear face of the housing, thereby forming a recess between them and the rear face. The surface mount 34 comprises a plate 46 having a surface facing side, a housing facing side, an upper end, a lower end and first and second opposite edges. In this embodiment, the surface mount is substantially rectangular with a central cut-out region, and is provided with apertures 48 to receive fixings, such as screws, to fix the surface mount to the surface. Each of the first and second edges are provided with first and second tabs 50,52, in the form of protrusions extending from the edge; the first tabs 50 extending from the edge at the upper end and the second tab 52 extending from the edge at the lower end. Tabs 50,52 are positioned on the housing facing side of the plate 46. A stop 53 is provided at the bottom of each tab 52 at the lower ends. In this embodiment, stop 53 is formed by a lip formed at the bottom of each tab 52. The housing is mounted onto the wall by aligning the tabs 50,52 of the surface mount with the recesses of the housing mount, so that the tabs engage with the recesses. The tabs are then slid downwards until they are fully inserted into the recesses, i.e. until the tab rests against stops 53. To remove the housing from the wall, the housing is lifted upwards to disengage the tabs from the recesses. Once removed, the surface bracket stays in place on the wall or other surface, ready for the housing to be reattached later. The tabs on the surface mount and the recesses on the housing mount are dimensioned so that the housing only need be moved a short distance vertically to be mounted on or removed from the wall or other surface. This configuration enables the housing to be removed and reattached to the wall without requiring the cables to be disconnected, as the relatively small movement can be accommodated by slack in the cables. In this embodiment, the length of the tab and recess is a minimum of 53mm. In other embodiments, the length of the tab and recess may be a minimum of 55mm, or 60mm, or 65mm. Once the housing is mounted on the wall, it is secured in place by a single thumb screw. Removing the thumb screw frees the connection box from the surface bracket, allowing the connection box to be removed from the wall. When cables are connected to the connection box, its movement is constrained. However, the small distance of travel required to release the housing from the surface mount enables the housing to be removed from the surface mount with cables still connected, making use of the slack in the cables. Therefore, after initial set up, the connection box can be removed from the wall whilst connections (i.e. cables) are live, so that further connections can be added to the box from a suitable work platform height. The ability to remove the connection box from the wall when adding further connections increases the efficiency of further installations. The bracket has been designed to reduce the time taken to install the box and increase the accuracy of the positioning. By separating the bracket from the connection box, a technician can ensure the bracket is mounted securely and straight whilst not being constrained by the box. Efficiency can be further improved by providing the surface mount with an integral level and adhesive. Furthermore, the surface mount is configured to space the connection box from the wall, protecting it from damp and mould. Cover A removable cover 30 is shown in more detail in Fig 12. The cover 30 is configured to fit onto the housing by a snap-fit connection. The cover has an inner surface, outer surface, a top edge 58, a bottom edge 60 and first and second side edges 62,64. The perimeter of the front face of the housing has a convex curve extending between A and B; this convex curve forms a curved rim 66. The top and bottom edges 58,60 of cover 30 are curved, configured to match the curvature of the rim 66. Incorporated into the top and bottom edges 58,60 is a resilient hook-shaped protrusion 68. In use, the cover 30 is positioned over the opening 28, with the curved top and bottom edges 58,60 of the cover aligning with the curved rim 66 of the housing. As the cover 30 is pressed down, the hook-shaped protrusions 68 encounter the rim 66 of the housing and deform outward over the rim 66, allowing the hook to move past the rim without obstruction. Once the hook has passed the top of the rim, it returns to its original shape, snapping back and engaging with the rim to create a secure fit. The rim now sits within the hook shape, effectively locking the cover on the housing. Whilst the rim 66 does not extend across the cable connection region, the bottom edge 60 of the cover 30 is able to engage with the rim 66 on either side of this region. The cover is released by reversing the process, unlatching the bottom of the cover and then the top. Figures 18A-18D are a cross section along B-B of Fig 17, each showing an enlargement of section C. They show the positions of the curved bottom edge and rim as the bottom edge is unhooked. Figures 20A-20C are a cross section along D-D of Fig 19, each with showing an enlargement of section D. They show the positions of the curved top edge and rim as the top edge is unhooked. As shown in Fig 12, the first and second side edges 62,64 are linear and parallel to one another. Side portions 70,72 are perpendicular from side edges 62,64, and in use extend into the interior of the housing. The interior is provided with an internal frame 69 having retention features 74,76 forming channels which in use receive the side portions 70,72 and act as guides to correctly position the cover on the housing. The cover has a secure fit with the housing to protect the internal components within the interior. This secure fit is provided at the top and bottom via the upper and lower edges 58,60 of the cover interacting with the rim 66 of the housing, and the cable connection region. The secure fit is provided at the sides by the side portions 70,72 of the cover interacting with the retention features 74,76 of the housing. The cover is further provided with a rubber gasket 77 within a channel, configured such that the rubber gasket presses against the housing when the cover is in position on the housing. The secure fit and rubber gasket ensure a waterproof seal. The snap-fit connection removes the need for mechanical fixings, which reduces the number of components in the connection box and increases the efficiency of installation. As shown in Fig 7, a security fastening 78, such as a screw, is provided to reversibly lock the cover to the housing. This ensures that the cover can only be unlocked using the correct tool and not a standard screwdriver. The security fastening 78 is received by apertures 80,82 in a side portion of the cover and a retention feature of the housing respectively. The security fastening can be accessed via a void formed between the cover side portion 70 and the rim 66 of the front face 14 of the housing. This arrangement has the advantage that that the security fastening is hidden from sight. This security fastening ensures that the connection box is tamper proof. Inlet and Outlet Modules The inlet and outlets are shown in more detail in Figs 21-22. The housing is provided with an input module 84 and outlet module 86, which are separate from each other, each module being releasably engaged within the cable connection region of the housing. In this embodiment, the input and output modules 84,86 are in sliding engagement with channels provided in the internal frame 69 of the housing. Once in place, they are secured by fixing means, such as screws. The use of removable inlet and outlet modules simplifies the installation of the connection box, as it enables the cables to be inserted whilst these modules are loose. As shown in Fig 23, the input module 84 has a base 88 and perpendicular panel 90. A compression cable gland 92 is mounted on the panel 90. It both secures the input cable and provides an airtight seal to keep out dirt, dust and moisture. The base 88 is provided with apertures to receive fixing screws. The outlet module 86 is shown in Figs 24-33. It is configured to receive multiple outlet cables. As shown in Fig 24, the outlet module 86 has a base 94 and a rectangular body 96. The base is provided with apertures to receive fixing screws to attach the module to the housing. The body has three pairs of apertures for receiving cables, the top pair of which is described in more detail. The body 96 has an outward facing surface 98 and an inward facing surface 100. A pair of cable-receiving apertures 102,104 extend from the outward facing surface 98 to the inward facing surface 100. In use, a cable is fed through each aperture 102,104, into the interior of the housing. Each aperture 102,104 is provided with a seal to ensure weather proofing. A slot 106 is located between the inward and outward facing surfaces, connecting the pair of cable-receiving apertures 102,104. A cable clamping mechanism is provided to hold the cables securely in place. This is in the form of a clamping means 108 provided in the slot 106. The clamping means 108 has two 12 clamping components 110,112, joined together by a linking member 114. Each clamping component is provided with a clamping surface 116 and a tapered surface 118. The tapered surfaces 118 of the two clamping components 110,112 form a V-shape in the clamping member. An actuator in the form of a cone tipped screw 120 is located in an aperture extending from the outward facing surface to the slot. The cone tipped screw 120 has a conical surface 122 positioned above the tapered surfaces 118 of the clamping components 110,112. In use, cables are inserted into the pair of cable receiving apertures 102,104, and the cable clamping mechanism tightened to clamp the cables in place. This is achieved by screwing the cone tipped screw 120 into the aperture, so that the conical surface 122 bears against the tapered surfaces 118 of the clamping components 110,112. As the conical surface 122 pushes down against the tapered surfaces 118, the clamping components are pushed outwards, breaking the link member 114. The clamping components are pushed towards the apertures, so that their clamping surfaces 116 push against the cables to hold them in position. The link member 114 is very thin, allowing it to break easily. Unscrewing the cone tipped screw 120 releases the clamping components, allowing the cable to be moved in order for future connections to be added. The clamping member can be replaced to enable future connections. The output module may be multiple pairs of apertures, for example 3 pairs, as shown in Figs 30-32.
