Definitions

  • This invention relates to adapters for moulded or other electrical plugs of the type which enable moulded or other plugs having a pin arrangement incompatible with that of a mains electricity socket, such as two-pin shaver plugs, to be connected to the mains.
  • this invention relates to an adapter, such as is disclosed in EP-A-342942, which is capable of retaining a moulded or other plug within itself comprising: an upper and a lower portion; a plurality of mains pins extending below the lower portion for connecting the adapter to the mains; means for securing a moulded plug, having at least two pins, within the adapter; means for effecting electrical contact between respective plug pins and mains pins; and means for movably securing the upper portion to the lower portion.
  • Such adapters shall hereinafter be referred to as "relevant adapters”.
  • references herein to a relevant adapter are to such an adapter in which the moulded plug can be retained in any orientation, in which the upper and lower portions may be completely separable or may be hingedly, slidably, rotatably or otherwise movably attached, and which may also include a middle portion retainable between the upper and lower portions. Additionally, the lower portion may comprise a box or frame into which the upper portion is slidable.
  • a relevant adapter wherein the upper and lower portions are moveable between a closed position wherein the adapter is compatible with, and may be plugged into, a mains socket and an open position wherein the adapter is incompatible with, and cannot be plugged into, the socket.
  • one mains pin preferably the earth pin, may constitute a release means movable between a first, locking, socket-compatible position and a second, releasing, socket-incompatible position.
  • the pin may be rotatable, or may form a lever, possibly provided with a pinion or cam as aforesaid.
  • one mains pin may be retractable within the adapter and include an internal head portion for contacting the moulded plug.
  • the mains pin cannot retract within the adapter.
  • any effort to insert the adapter into a socket will result in the pin being pushed into the adapter, thereby displacing the moulded plug from its retained position.
  • the upper portion of the adapter may carry at least one of the mains pins and the lower portion the remaining mains pins.
  • the upper portion carries the earth pin and the lower portion the remaining pins. In this way, when the upper and lower portions are released from one another, the mains pins are no longer configured to correspond with a mains socket.
  • a further alternative is that when the upper and lower portions are in the open position, at least a part of the upper portion projects below the lower surface of the lower portion. This prevents the adapter being re-inserted into a socket until the upper and lower portions return to the closed position.
  • the upper and lower portions may, for example, be hingedly connected, or slidably connected by means of arcuate sliding surfaces, e.g. an arcuate groove in one portion co-operating with an arcuate ridge or bead on the other portion.
  • Preferably means are provided for securing a moulded plug within the adapter and comprise retaining means adapted to co-operate with features of relief of the moulded plug.
  • the retaining means may comprise a moulded recess in either the upper or the lower portion of the adapter.
  • a moulded recess it is envisaged that the mass of material, preferably plastics material, in which the recess may be provided may be finned, or comprise a plurality of projecting pegs, with the edges of the fins, or the ends of the pegs, defining the contours of the recess. This arrangement has the attendant advantage of a reduction in the quantity of material required for the moulding.
  • the features of relief may comprise projections or indentations in a shoulder portion, a body portion, a pin or pins or a tail portion of the moulded plug, in which case the retaining means may also comprise corresponding indentations or projections.
  • the positioning of the features of relief and of the corresponding retaining means may be dependent upon the fuse rating required by the appliance to which the moulded plug is connected and the rating of the fuse carried by the adapter respectively.
  • the retaining means may comprise means adapted to receive and locate at least one pin of the moulded plug.
  • the retaining means include a hole in, or a groove in an edge of, an internal wall of the plug and conveniently there is one such hole for each pin.
  • the internal wall may be integrally formed with the upper or the lower portion of the adapter, or may be part of a separate internal portion which is retained by the upper and lower portions.
  • the internal wall may be provided with a further hole for passage of a fuse.
  • the retaining means may also include an exit hole or slot in either the upper or lower portion of the adapter which is sufficiently large to permit passage of the cable to which the moulded plug is attached but is not large enough to accommodate any part of the moulded plug. In this way, the moulded plug may be retained between the internal wall and the portion of the adapter surrounding the exit hole or slot.
  • the retaining means may comprise a key lockable, for example by rotation, in a recess in the moulded plug.
  • bperating means for engaging and disengaging the key are provided on the underside of the lower portion of the adapter. This ensures that the moulded plug can only be disconnected etc. when the adapter is removed from a mains socket.
  • the means for securing a moulded plug within the adapter may be such as to permit insertion of a moulded plug when the upper and lower portions are secured to one another but to permit its removal only when the upper and lower portions are separated.
  • the means for securing a moulded plug may include one or more inwardly opening flaps in the upper or lower portion movable between a closed and an inwardly opened position.
  • the flap or flaps are biassed towards the closed position, for example by a spring or springs.
  • the means for effecting electrical contact between respective plug pins and mains pins may comprise contact means whereby such contact is effected upon securement of the upper portion of the adapter to the lower portion.
  • the contact means may comprise first contact means in the upper portion for receiving the plug pins in electrical contact and second contact means in the lower portion for effecting electrical contact between the first contact means and the mains pins on securement of the upper portion of the adapter to the lower portion.
  • the contact means may comprise means for retaining a fuse or conductor in the upper portion of the adapter and a pair of contacts in the lower portion, the fuse or conductor bridging the pair of contacts on securement of the upper to the lower portion.
  • the pair of contacts may include a moulded plug pin, or one end of a fuse, or both.
  • the contact means comprises a switch, preferably in the live pin circuit, in the lower portion of the adapter, biassed into an open position, but which is closed by closing means on the upper portion upon securement of the upper portion to the lower.
  • the switch may comprise a reed switch and the closing means may comprise a magnet for closing the reed switch on securement of the upper to the lower portion.
  • the reed switch may be incorporated into a fuse.
  • the switch may comprise a pair of contacts located adjacent, but biassed away from, one another and the closing means comprises a projecting wedge or pin which moves one contact such that it touches the other.
  • the closing means comprises a projecting wedge or pin which moves one contact such that it touches the other.
  • Release means may be disposed on the lower surface of the lower portion of the adapter operable to permit release of the upper portion from the lower portion. As can readily be seen, in order to release the upper portion from the lower, the adapter must be removed from a socket in order for access to the release means to be obtained.
  • the release means may comprise a pin located in one portion and biassed into engagement with a hole or recess in the other portion, the pin being movable out of engagement with the hole or recess.
  • the release means may comprise a cam rotatable to release the upper and lower portions of the adapter from one another.
  • the cam is biassed into a position in which the two portions are secured to each other.
  • the release means is movable between a first, locking position and a second, releasing position wherein it projects below the lower surface of the lower portion, and is capable of adopting the locking position only when the upper and lower portions are in the closed position.
  • the release means may comprise a lever provided on the lower portion and pivotable between a locking position flush with the lower surface of the lower portion and a release position.
  • the end of the lever remote from its free end may be provided with a pinion for co-operating with a rack on the upper portion or may be provided with a cam for co-operating with a recess therein.
  • the adapter and a moulded plug retained therein cannot be separated while the adapter remains plugged into a socket.
  • At least the lower surface of the lower portion is provided with an access aperture through which the moulded plug may be inserted or removed.
  • the access aperture may be so dimensioned as to conform with the shape of the moulded plug, or may be larger than the plug.
  • the adapter may also require removal from a socket not only for change of plug, but also for separation of the upper and lower portions.
  • the upper portion may be provided with the gripping handle in order for it more easily to be used by individuals whose grip, for example because of disease, is relatively weak.
  • the mains pins and the means for effecting electrical contact between the mains and plug pins may comprise a mains pin, connecting track and plug pin receiver integrally formed from stamped copper sheet or other conductive sheet material.
  • the track comprises at least a partial twist to allow for relative movement of the plug and mains pins.
  • the adapter may be provided with an internal flap movable between an inwardly swung, closed position and an outwardly swung, open position, and covering the opening through which the moulded plug or its cable passes. This prevents anything being inserted into the adapter without the upper and lower portions first being separated or opened.
  • FIG. 1 there is shown a lower portion (2) of a relevant adapter, provided with mains pins (3, 4).
  • Mains pin (4) is connected via a conductive track (10) to a plug pin receiver (5).
