Description
SPECIFICATION
Electrical Terminal Box
This invention relates to an electrical terminal box having a front plate fitted with one or more switches and/or provided with sockets for reception of one or more electrical plugs.
Such terminal boxes must be readily accessible for operation ofthe switches and/orthefitting of electrical plugs, but this has certain disadvantages. In the home, accidents have occurred when young children have played or tampered with the switches, socket aper tures or plugs. It is knownto position electrical terminal boxes with socketapertureswell above the floorsothatthey are outof reach of small children, but such terminal boxes, which arethen in a prominent position, are generally unattractive in appearance, particularlywhen fitted with plugs. In the workplace, theswitchesorsocket apertures on the front plate may become damaged by impactof contaminated by grease orfluids used in the workplace.
According to the present invention there is provided an electrical terminal box having a front plate fitted with one or more switches and/or provided with socket apertures for reception of one or more electrical plugs, wherein the terminal box isfitted with a cover adapted to co-operate with the front plate to at least partially enclosethe switch or switches and/ora plug or plugsfittedin the socket apertures, the cover being detachableorrnovable into anopen position to permit operation ofthe switch and/or the fitting or removal of a plug-from the socket apertures.
The caverontheelecfrical terminal box, when fitted in position, prohibits or at least restricts access to any switches, socketapertu res, or electrical plugs on the front plate ofthe terminal box, but the cover does not interferewith the primary function of the terminal box.
The cover is preferably arranged so that it can easily be detached or moved into the open position by an adult but not by a small child. Thus, when the cover is intheclosed position, small children are notableto insertforeign objects into the socket holes, or insert or remove ptugs from the socket apertu res, or operate any switches.
In addition, the cover when in the closed position at least partially obscures the switches, socket apertures and plugs (ifany) from view, and can be less unattractive than a terminal box having exposed switches, socket apertures or plugs.
In a wo rkpl ace;th e covercan be used to protect the switches, socket aperturesand plugs from damage or contamination by grease orfluids used in the workplace.
The cover may be pivotally or detachably mounted ononeofthecomponentsoftheterminal box. Ina preferred arrangement however, the cover ispivotally or detachably mounted on a back plate fitted between the front plate and tile external casing pf the terminal box
Thus according to the invention there is also
provided a protection device for use with an electrical terminal box of a predetermined size and comprising an open external casing closed by a front plate fitted with one or more switches and/or socket apertures for reception of one or more electrical plugs, said device comprising a back plate adapted to be clamped between the casing and the front plate with part of the back plate projecting laterally outwards beyond the periphery of the front plate, a cover, and means four mounting the cover in a closed position on the back plate so as to at least partially enclose any switch, socket apertures or electrical plug on the front plate, the cover being detachable or movable into an open position to permit the operation ofthe switch or the fitting or removal of a plug from the socket apertures.
In the device ofthe invention the cover may be a snap fit on one or more lugs on the back plate, or the cover may be pivotally mounted on the back plate and held in position by one or more latches or buy a snap fit engagement with one or more lugs on the back plate.
The back plate can conveniently beformedfrom a rectangular sheet away atthe centre to form a large central opening for passage ofthe electrical cables and terminals attached to the rearofthefront plate.
One construction of a back plate and coverforfitting on an electrical terminal box in accordance with the present invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Figure lisa front elevation ofthe back plate when in an upright position,
Figure 2 is a plan view ofthe back plate of Figure 1,
Figure 3 is an end elevation ofthe back plate of
Figure 1.
Figure 4is a front elevation of the back plate and coverfittedonanelectricalterminal boxon a wall.
Figure 5 is a plan view ofthe back plate and cover of
Figure4,
Figure 6 is an end elevation ofthe back plate and coverofFigures4and 5,
Figure7 is a sectional view ofthe back plate and covertaken along either of the section lines A-A or B-B in Figure 4, and Figure8 is a sectional view ofthe back plate and covertaken along the line C-C in Figures 4.
The back plate and cover shown in the drawings are designed to fit on a 3-pin electrical socket terminal box of conventional construction according to British
Standard 1363 and comprising an open-fronted rec tangular casing and a front socket plate closing the front of the casing, the front plate being formed with three apertures or multiples ofthree apertures for reception ofthe pins on an electrical plug and the rear of the front plate being fitted with the electrical terminals which are housed within the casing, when the front plate is fitted on the casing.The front plate has substantiallythe same overall length and breadth dimensions as the external length and breadth dimensions of the casing, and the front plate is formed with a rearwardly projecting flange around its periphery which abuts against the front edge ofthe wall of the casing when the front plate is fitted on the casing. The
front plate is held in position on the casing by screws
extending through apertures in the front plate and
engaged in screwthreaded holes in pillars formed on the base ofthe casing. In domestic dwellings, the terminal box is commonly mounted in a recess in the wall with the front edge ofthe wall ofthe casing flush with the surface ofthe wall.The terminal box may
however be mounted directly on a wall surface, or on a
panel, or on electrical trunking, orthe terminal box
may be connected to an extension lead and adapted to rest on atable oron the floor. Thefront plate ofthe terminal box may be provided with one or more switches for controlling supply of electricity to the terminals associated with the aperturesforthe electrical plug or plugs.
Referring nowto Figures 1-3, the back plate 10 comprises a rectangularsheet of resilient plastics material which is cut away atthe centre to form a narrowborder stri p defining a large central opening 11. The back plate has overall dimensions greaterthan those ofthe front plate, and the central opening 11 has length and breadth dimensions a few millimetres smallerthan the length and breadth dimensions ofthe interior ofthe casing which is shown in broken lines at 12 in Figure 1. Thefrontface ofthe back plate lOis provided with two lugs 13 arranged one at each end of the back plate.The outer end faces 14 of the two lugs 13 are tapered towards one another in a direction away from the frontface ofthe plate 10, and each of the end faces 14 is formed with a part-spherical recess 15 as shown in Figure 2. The front face ofthe back plate is also provided with four locating pins or projections 16 arranged one at each corner ofthe back plate adjacentthe central opening 11. The inner periphery ofthe back plate is formed with two inwardly projecting lugs 17 arranged one at each end and adapted to overlie the pillars on the base of the casing, thelugs 17 having apertures 18forreception ofthe screws holding the front plate onto the casing. The back plate can conveniently be formed by a moulding operation.
The cover 20,shown in Figure 4-8, is substantially dome-shaped with overall length and breadth dimensions substantially the same as those of the back plate 10, and the internal walls of the cover 20 are formed with two part-spherical protrusions 21 arranged one at each end of the cover and adapted to engage as a snap fit in the part-spherical recesses 15 on the lugs 13 on the backplate when the cover is fitted on the back plate. The rear edge of the bottom wall ofthe cover is cut awayto fromtwo semi-circularopenings 22 as shown in Figure 8 for passage of electric cables connected to electric plugs as described hereinafter.
The cover 20 can conveniently be moulded in resilient plastics material.
In use, the back plate 10 is mounted on an electrical terminal box by first unscrewing the front plate from the casing and removing the front plate from the casing. The electric cables attached to the terminals on the rear ofthe front plate are then partly withdrawn from the casing, and the front plate together with the cables passed through the opening 11 in the back plate. The borderstrip defining the lower edge ofthe opening 11 in the back plate may, if desired, have a slit extending obliquely, across its full width, as shown in
broken lines at 19, to facilitate mounting the back plate
around the cables.The back plate 10its then mounted
on the rear of the front plate with the locating pins 16
engaged againstthe internal peripheryofthe pre
viously described rearwardly projecting flange on the
front plate, the front plate and back plate placed on the
front edge of the wall of the casing (shown at 12 in
Figure 1), and the front plate screwed back onto the casing with the back plate clamped between the front edge ofthe wall of thecasing and the rearwardly
projecting peripheral flangeon the front plate, andthe screws extending through the apertureS 18 in the back plate.The cover 20 can then befitted orrthe back plate 10 with the protrusions 21 engaged asa sreapfit in the recesses 15 on the lugs on the back plate'. The tapered' end surfaces 140n the lug l3actascam surfaces which force the ends ofthe coveraway fro.m one anotherto permit the protrusions 21 to slide up the end surfaces 14 and into the recesses 15 when the cover is being fitted on the back plate.
The cover 20 is of a size such that it will accomimo- date electrical plugs fitted in the front plate, the cables attached to the plugs passing through the openings 22 in the bottom wall ofthe cover.
Instead of the locating pins 16, the back plate 10 may be provided with other locating pins or projections arranged to engage the external periphery ofthe front plate orthe internal or external periphery of the casing and thereby centre the back plate relative to the front plate orthe casing during the fitting ofthe back plate to the terminal box. Alternatively, the locating pins may be omitted and the engagement ofthe screws within the apertures 18 relied upon to centre the back plate relativetothefront plate and casing.
The back plate 10 can conveniently be thin and flexible when it is to be used with an electrical terminal box in which the casing is embedded in a recess in a wall with the front edge of the wall ofthe casing flush with the surface ofthe wall, since then the back plate 10 lies along the wall, as shown in Figure 5-8 ofthe drawings, and the wall supports the back plate during fitting ofthe cover as a press fit on the lugs on the back plate.
In an arrangement in which the casing projectsfrom the wall, the back plate is preferably made of a rigid material to provide the resistanceforthe press fitting of the cover onto the back plate.
Instead ofthe cover being a press fiton lugs on the back plate, the cover may be hinged.taithe back plate at one end or one sidethereoffor pivotal rtovement between a closed position in whichtlteco.veratleast partially encloses the front plate, theelectrical switches and any electrical plugsfitted:in,thefrontplate, and an open position permitting tkefittlng or removal of the electrical plugs. The covermay be held in the closed position by any suitable catch or snap fit connection. The cover and back plate can then conveniently comprise asingle moulding of resilient plastics material, the cover being connected to the back plate by a hinge portion permitting pivotal movement ofthe cover relative to the back plate, and the back plate having a central opening for passage of the electrical cables in an electrical terminal boxwhen the device is fitted thereto.
The back plate and cover shown in the drawings is designed for use with a standard electrical socket of conventional construction. The front plate or the casing may however be adapted to provide a suitable baisieonwhich a cover can be detachably mounted.
Therewould then be no need to provide a back plate.
