DETAILED DESCRIPTION

[0042] The present invention relates to power safety devices, including power safety devices configured for outdoor use. For example, embodiments include power safety devices which provide overload protection for caravans when connecting to mains power supplies.

[0043] In overview, embodiments described below are configured to provide low complexity weather resistant power safety devices, for example power safety devices in the form of electronic enclosures (i.e. power safety devices which provide an enclosure in which electrical components and/or couplings are protected from external environmental conditions). It will be appreciated that the various embodiments illustrated and described share various key features, and similar numbering has been used across the diagram to denote corresponding features. Low complexity is achieved by, for example, reducing a number of components, providing straightforward weather seals, and facilitating streamlined construction.

[0044] FIG. 1 illustrates a power safety device 100 configured for outdoor use, and this embodiment is described in detail below. Alternate embodiments of device 100 are illustrated in FIG. 2 and FIG. 3.

[0045] Device 100 includes a sealed container 101 having an upper portion 102 and a lower portion 103. It will be appreciated that portions 102 and 103 may be formed via a plastic injection moulding process, or vis other processes.

[0046] In the illustrated embodiment, portion 102 and 103 are coupled via an external hinge 104, which has interlocking hinge components defined via each of portion 102 and 103. Hinge 104 allows for container 101 to be positioned in an open configuration (illustrated) and a closed configuration. In the closed configuration the portions are snap lockingly engaged to one another, for example via formations 105 and 106 which are respectively integrally formed with portions 102 and 103.

[0047] In a further embodiment, the hinge arrangement is omitted, with the two portions being separate in the open configuration and snap-lockingly engaged in the closed configuration.

[0048] In the embodiment of FIG. 2, 105 and 106 are replaced by a lid latch 190, which couples portion 102 to portion 103 via a snap lock arrangement. It will be recognised that apertures formed in portions 102 and 103 for this purpose are disposed laterally outside of container sealing infrastructure.

[0049] The sealing of container 101 is achieved via a sealing arrangement, which is discussed in more detail further below. This sealing requires a minimised number of sealing areas thereby to reduce complexity and improve weatherproofing reliability.

[0050] A pair of apertures are formed in the sealed container, each being configured for allowing sealed egress of respective power lead from the container (see lines 107 and 108).

For the present purposes, these are described as an outlet aperture (line 107) and an inlet aperture (line 108). However, in further embodiments the inlet and outlet roles are reversed. In some embodiments a differentiating factor between the apertures is that one is for a permanent lead, and the other for a removable lead (i.e. a lead with a plug that is attached to a socket on the device).

[0051] In some embodiments, there may be an additional one or more apertures beyond the pair. For example, where the pair includes one aperture for a permanent lead connection, the additional apertures may include one or more additional apertures for temporary leads. For example, see the embodiment of FIG. 4, where there are three additional apertures for connection of respective additional leads. In that example, the device performs a role as a power bank for multiple devices.

[0052] In use, the inlet aperture allows egress of an inlet lead 110, which may, for example, be coupled (directly or indirectly) to a conventional power supply via a plug 111. The outlet aperture allows egress of a lead which is coupled directly at its proximal end to a electrical socket 112 within container 101, and coupled at its distal end (directly or indirectly) to a target device (which is typically an outdoors device, such as a caravan).

[0053] A component capture array 115 is integrally formed from portion 103. This is configured to adjacently capture and locate: (i) a power safety component 116 and (ii) electrical socket 112. In the illustrated embodiment this is achieved via formations which define vertical sleeves into which component 116 and 112 are vertically inserted thereby to restrict lateral movement. In the illustrated embodiment component 116 is a DIN rail device, and array 115 is configured to receive the DIN rail device vertically.

[0054] A component capture securing member 118 is mounted with respect to the component capture array 115, thereby to securely hold the power safety component 116 and the electrical socket 112 (this restricts vertical movement, and further inhibits horizontal movement). In the illustrated embodiment member 118 includes vertical sleeves corresponding to those in array 115, and is held in place via screws 119 which thread into formations defined on array 115 (or elsewhere on portion 103). These screws provide a strong clamping force between member 118 and portion 103, which restrains socket 112 in place even in spite of lateral forces along the axis of the lead (for example "tugging" forces) which may be applied in practice via the outlet lead. In the example of FIG. 1 a region of an outer face of socket 112 abuts against a region of an inner face of member 118, thereby to improve security from lateral movement.

[0055] It will be appreciated that there are benefits from having array 115 and member 118 contained within the sealed contained in use, for example in terms of reducing risk of corrosion for screws 119.

[0056] Member 118 includes an aperture 120 which, in use, allows for manual manipulation of a movable member on component 116. For example, in the illustrated embodiment, component 116 is a DIN rail device including surge protection (forexample a RCBO or MCB) and having a switch 121, and aperture 120 allows viewing and manual manipulation of switch 121. Other components may include: an RCD (only), a surge protector (for which access through the allows a user to replace a blown cartridge, whilst the rest of the DIN rail housing stays in place), and/or a power meter (for example with a display).

[0057] In the illustrated embodiment, portion 102 is formed of transparent plastic, thereby allowing a user to view a status of device 116 (e.g. switch 121) in use whilst the seal container is in a closed configuration. When the sealed container is in an open configuration, a switch component of the safety component is manually manipulatable.

[0058] Although the component capture array 115 is illustrated as being integrally formed from portion 103, in other embodiments it is an insert that is mounted to portion 103. In further embodiments the component capture array is defined by or mounted to portion 102.

[0059] It will be appreciated that electrical socket 112 is located such that an electrical plug is insertable into the socket and contained within the sealed container, with an associated power lead egressing through the outlet aperture (line 107).

[0060] In the illustrated embodiment, the outlet aperture (line 107) is configured to receive a power output lead via a sealed arrangement defined in part on the upper portion and in part on the lower portion. This is achieved via resilient sealing blocks 131 and 132, as discussed below.

[0061] In the illustrated embodiment, container 101 is sealed in two sections: a first section along a peripheral edge of portion 103 in a clockwise direction from a point 151 to a point 152 (the long path between those points along the top peripheral edge of portion 103), and a second section between points 151 and 152 in an anticlockwise direction (the short path along the top peripheral edge of portion 103).

[0062] For the first sealing section, the top portion 102 has a peripheral tongue, and the bottom portion 103 has a complimentary peripheral groove (these may be reversed in other embodiments). The groove extends from point 151 to point 152 in a clockwise direction, and the tongue is complementarily formed to engage into the groove upon closing of the container. A resilient sealing member 153 is inserted into the groove from the end to end, such that the when the container is manipulated into the closed configuration, the peripheral tongue and peripheral groove define a clamping engagement around the resilient sealing member thereby to create a peripheral seal from point 151 to point 152. The container is configured such that upper portion is locked to the lower portion when the container is manipulated into the closed configuration, thereby to maintain the seal.

[0063] Sealing member 153 may be formed of a material such as silicone or neoprene. Alternately, a cast-in-place or cure-in-place gasket may be used, which consists of a liquid precisely dispensed (for example by robot) into the sealing channel, where it cures.

[0064] Points 151 and 152 define junctions between the ends of the peripheral groove and a sealing block compartment 142. Likewise, points 161 and 162 define junctions ends of the peripheral tongue and a sealing block compartment 141. Sealing blocks 131 and 132 are respectively inserted into compartments 141 and 142 during manufacture, and held in place by adhesives or an oversizing/friction arrangement.

[0065] The sealing block receiving compartments each include aperture defining formations which collectively define a first aperture of the pair of apertures, wherein for each sealing block the aperture defining formations include an inner formation and outer formation which are positioned on opposite sides of the sealing block (these are in the illustrated embodiment semicircular notches). Via this arrangement, in use, an electrical lead is configured to be inserted between the aperture defining formations of the first and lower sealing block compartments upon closing of the sealed container. The closing of the container causes resilient deformation of the sealing blocks 131 and 132 around the electrical lead, thereby to create a seal between points 151 and 152 on portion 103, and between points 141 and 142 on portion 102. As such, the resilient sealing member 153 and resilient sealing blocks 131/132 create a full peripheral seal of container 101 when the container is in the closed configuration.

[0066] Sealing blocks 131 and 132 may be rectangular prism blocks, or more complex shapes (for example as shown in FIG. 2). These may be formed, for example, from silicone or polyurethane, solid or foamed. In one embodiment a porous silicon orpolyurethane block is cast/moulded over an injection moulded frame.

[0067] In the embodiment of FIG. 1, the peripheral groove includes a notch which in part defines the inlet aperture. Lead 110 is inserted into that notch, such that a grommet 180 having a special grommet region 181 which replicates in profile the peripheral channel seals the container at that region (in combination with an additional grommet seal 182 and housing seal 153).

[0068] In alternate embodiments shown in FIG. 2 and FIG. 3, the inlet aperture is instead defined by a hole 170 formed in portion 103, and a sealing grommet 171 on lead 110 seals the inlet lead as it passes through that hole. In this alternate arrangement, assembly is more difficult as the wiring loom cannot be fully pre-assembled given that the plug lead has to be fed into the housing before being connected to the DIN rail device. However, there is a benefit in terms of a lower part count, as the resilient grommet is employed to seal aperture 170, a more robust product, and a more secure lid to housing seal.

[0069] In the alternate embodiment of FIG. 2, the DIN rail device is mounted horizontally, and the switch is accessible via a region in between component capture securing member 118 and component capture array 115.

[0070] The alternate embodiment of FIG. 4 is similar to the embodiment of FIG. 3, although a single input lead is connected (via the DIN device) to multiple power outlet sockets having respective lead apertures. It will be appreciated how any of the embodiments of FIG. 1 to FIG. 3 could be re-sized to accommodate multiple outlet sockets and lead apertures. In the embodiment of FIG. 4 there is a one-to-one relationship between the DIN device and the input lead; in an alternative there is a is a one-to-one relationship between the DIN device and the output leads (i.e. each output can have a separate surge protector). In further embodiments there is a two-to-one relationship between the DIN device and the output leads.

[0071] FIG. 4 also shows a modified clip arrangement, included to provide additional strength given that there may be multiple output leads.

[0072] It will be appreciated that the diagram in FIG. 4 is shown in an assembled view (rather than an exploded view), and that various reference numerals have been excluded for the sake of simplicity.

[0073] Advantages of the illustrated embodiments include:

• The lower housing (portion 103) securely locates the electrical components provides the main structural member.

• The component capture securing member 118 provides an inner housing which protects and isolates the electrical components.

• The socket is captured securely between the lower and inner housings, providing significant holding force.

• A lead clamp which prevents the plug-lead pulling out; this is part of the lower and inner housings, eliminating a component (a conventional P-clip which would require a screw).

• Plug lead entry seal is achieved either with just the grommet (sidecore design of FIG. 2 and FIG. 3), or open, in combination with the housing seal 153 (without the sidecore) as per FIG. 1.

• The number of fasteners (screws) is minimised, and other than the hinge, these are all contained within the housing to eliminate leaks and to minimise corrosion.

• Portion 102 provides a lid which closes over the whole assembly and isolates it from dust and liquid ingress. Being transparent, this allows inspection and being releasably attached (hinged as shown, latched closed using integrally moulded or separate clips or toggles), allows physical interaction with the DIN rail device.

• Lead seals are provided by reliant blocks 313 and 132 in the lid and lower housing which seal around the user's lead.

* One single housing seal (no separate lid or screw-boss seals).

• Integrated (plug) cable clamp - eliminates separate P-clip or clamping piece

* Minimum number of fasteners.

• Grommet serves double purpose as strain relief and plug-lead hole seal.

• Integrated latches

• Minimum number of separate seal locations (plug entry, housing & lid, socket lead entry).
