Abstract

Plug-in transformers are commonly provided for the battery-recharging circuit of a hand-held calculator and other similar uses. When the power requirements of the transformer and/or other power-pack components, desirably included in the plug-in unit, are larger, the resulting weight may exceed that which can be safely and reliably supported by a single set of plug-in prongs.

Wall Mounted Plug In Power Pack

Plug-in transformers are commonly provided for the battery-recharging circuit of a hand-held calculator and other similar uses. When the power requirements of the transformer and/or other power-pack components, desirably included in the plug-in unit, are larger, the resulting weight may exceed that which can be safely and reliably supported by a single set of plug-in prongs.

The illustrated configuration plugs into both receptacles of a standard convenience outlet so as to receive substantially increased support from the outlet. Referring to the drawing, power-pack body 10 has two sets of prongs 12, 14, one set to be plugged into each of the sockets of a standard two-socket wall outlet (not shown). Thus, body 10 receives mechanical support from both sockets.

One set 12 of prongs provides electrical power to the power pack. Optionally, body 10 also includes another outlet 16 electrically connected to the other set 14 of prongs to provide electrical service for other uses. If desired, a screw hole 18 can be provided so that the usual face-plate screw (not shown) can be used to provide additional mechanical support. However, by use of both 12 and 14, sufficient support is usually achieved without this, and the wall outlet face plate can be left undisturbed.
