Abstract

An electric plug adaptor (10, 120, 220) has a body (11 etc) with one side or end adapted to receive a subject electric plug (20) and the other side or end having at least one pin (13) adapted to be received within an entry of a target electric socket. The body (11 etc), including the at least one pin (13 and/or 17A, 17B), is preferably moulded in one-piece from insulating plastics material. The at least one pin (13 and/or 17A, 17B) is a non-conducting 'dummy' pin that can serve a location and/or other purpose in the target socket, or contribute to making up size difference between actual target plug pin(s) (21A, 21B) and socket entry provision(s). The body (11 etc) has means (15A, 15B) to cooperate in supporting the subject plug (20) and allowing direct electrical connection between it (20) and the target socket.

Description

TITLE: ELECTRIC PLUG ADAPTOR DESCRIPTION
TECHNICAL FIELD
The invention relates to electric plug adaptors such as used by travellers outside their own countries, particularly to enable them to use electric plugs of one standard type (herein "subject" plugs), typically for their own country, in electric sockets of another standard type
(herein "target" sockets), typically for another country, with which their plugs do not fully match.
For example, "subject" plugs as standard in continental Europe have two usually quite thin round- section pins, and "target" sockets as standard in the United Kingdom have entries matching plugs having three flattish rectangular-section pins. We have noted that, however fortuitously and unintentionally, the European pins are spaced sufficiently similarly to U.K. live and neutral pins that a continental European plug ought to be capable of being inserted into corresponding entries of a U.K. socket if shutter-like entry shielding of the latter is opened, but then unlikely with anything like satisfactory and secure relative location physically.
BACKGROUND ART
However, common known adaptors generally comprise a body, usually of a moulded plastics insulating material, having one side or end with metal pins to match and enter into electrical connection with a target socket, and another side or end adapted to receive metal pins of a subject electric plug into electrical connection within the adaptor between the subject plug pins and contacts provided- on the adaptor pins. Because these adaptors have both metal and plastics parts manufacturing them involves more than one stage, often including plural assembly stages, and is therefore quite expensive both in terms of time and parts.
An object of the present invention is to provide an alternative electric plug adaptor, at least for European subject plugs and U.K. target sockets, which is relatively easy and cheap to manufacture.
DISCLOSURE OF INVENTION Some general aspects of invention arise for electrical adaptors hereof and/or features advantageous individually or in combination, as follows :- adaptor body that is free of electrical contacts for either of subject plug or target socket, but cooperates with both to permit direct electrical connection between them; adaptor body with dummy pin provision(s) that may be integrally formed as by one-piece moulding, which dummy pin provision is to enter the target socket for location and/or other purposes, say including opening of shutter provisions at other socket entry or entries; adaptor body with dummy pin provision(s) sized up to difference between adjacent subject plug pin(s) and target socket entry or entries, preferably thinner at least in their dimension to enter between socket contact parts; adaptor body with dummy pin provision(s) formed integrally as by one piece moulding from suitable insulating material.
One embodiment of the present invention provides an electric plug adaptor having a body with one side or end adapted to receive a subject electric plug and the other side or end having at least one pin adapted to be received within an entry of a target electric socket, characterised in that the body, including the at least one pin, is moulded in one-piece from insulating plastics material, the at least one pin thus being a non-conducting 'dummy' pin; and that the body has means to cooperate in supporting the subject plug and allowing direct electrical connection between it and the target socket. The body of the adaptor may conveniently have holes through which actual contact pins of the subject electric plug can extend and protrude from the adaptor to afford the desired electrical connection when the adaptor is inserted in the target socket, including its at least one 'dummy' pin and the subject plug pins going into entries of the target socket. This dummy pin can be for earth entry of a U.K. three pin socket and serve to open shielding of other entry provision.
The body of the adaptor may, or may further, have one or more dummy pins sized smaller than intendedly corresponding entries of the target socket and provided adjacent holes in the adaptor body for passage and protrusion of one or more actual pins of the subject plug that are also smaller than said intendedly corresponding entries so that both of adjacent said smaller dummy and actual pins are accepted together by those entries of the target electric socket, preferably with the dummy pins narrower than the actual pins as entrant contact making provision of the target socket.
The body of the adaptor may take any of several forms and shapes, say ranging from a simple plate with dummy pins to one side and through-holes, through such a plate with side walls or other dishing about the subject plug and/or inside grip-aiding flanging, to rearward walling closely matching to exterior of a subject plug through its thickness, even retaining of the subject plug whether by side gripping or by a top for a walled said plate, i.e as a housing partially or wholly surrounding or enclosing the subject plug when associated with the adaptor.
BRIEF DESCRIPTION OF DRAWINGS
Practical implementation for this invention is now described and diagrammatically illustrated, by way of example, in and with reference to the accompanying drawings, in which:-
Figures 1, 2 and 3 are outline top, bottom and complex part sectional views, respectively, for one embodiment;
Figures 4 and 5 shows perspective views of from opposite ends of a more detailed adaptor embodiment, including actual plug pins only in position in Figure 5; and
Figures 6 and 7 are similar perspective views of another embodiment of adaptor.
BEST MODE FOR CARRYING OUT THE INVENTION
Figures 1 and 2 show section lines A-A and A'-A' for
Figure 3, including differing to show transition through thickness of main plate 11. Basically, these (and the other) Figures are concerned with an electric plug adaptor
10 (110 and 210) for using a European round two-pin
"subject" plug in a U.K. "target" socket intended for a
U.K. rectangular/flat three-pin plug. As noted above, it happens that the pins of such a European subject plug are spaced similarly to corresponding (live and neutral) two of the pins of such a U.K. plug, sufficiently for the two pins of the European subject plug to fit into the live and neutral entries of the U.K. target socket so long as its normal shutter-type shielding of those entries is opened up.
The main plate 11 of the adaptor of Figures 1, 2 and 3 is shown with a fixed, actually integral, extension 13 from one side in the form of a dummy pin. The size and shape of the dummy pin 13 is the same as, or sufficiently close to that of, a normal earth pin of a U.K. rectangular/flat three pin plug for entry into the corresponding socket hole and operating shutter-type shielding to open up the other socket entries, i.e. for live and neutral pins.
The adaptor main plate 11 also has two through-holes 15A and 15B shown of round shape and spaced in order to accommodate passage of, preferably reasonably closely match to, the two contact-making pins 21A and 2IB of the subject (i.e. typical continental European electric power) plug 20. The locations of the through-holes 15A and 15B, including relative to the dummy pin 13, are such that the contact- making pins of the subject plug 20 can be inserted into the live and neutral entries of the target socket as the dummy pin 13 enters the earth entry of the target socket.
In addition, the adaptor main plate 11 has two other fixed, actually integral, extensions 17A and 17B in the form of dummy pins. The locations of the dummy pins 17A and 17B are alongside and flanking the through-holes 15A and 15B, actually outside the latter for a subject plug 20 with its pins 21A and 21B located and spaced substantially matching inner sides of standard live and neutral pins for a U.K. rectangular/flat three-pin electric power plug. In other words, the dummy pins 17A and 17B are spaced a little more than the holes 15A and 15B, actually with outer sides substantially matching those for a U.K. rectangular/ flat three-pin electric power plug, the dummy pins 17A,B and the actual pins 21A,B together making up substantially match the widths of said U.K. live and neutral plug pins at least as far as allowed by the actual pins 21A,B of the target plug 20.
The thicknesses of the dummy pins 17A and 17B should not be greater than the diameters of the actual pins 21A and 21B of the subject plug 20. In practice, it is preferred that the dummy pins 17A and 17B be slightly thinner, thus helping assure making electrical contact by the actual pins 21A and 21B of the subject plug 20 in the target socket.
The thickness of the adaptor main plate 11 should not be more than will result in the actual pins 21A and 2IB of the subject plug 20 protruding to at least minimum extents required for making satisfactory electrical contacts within the target socket, nor be less than would otherwise result in protrusion of the actual pins 21A and 2IB too far for satisfactory contact-making accommodation within the target socket.
Figure 3 in particular indicates some (but obviously not all possible) variations for adaptors embodying this invention. Thus, the main plate 11 is shown rectangular rather than any other shape that could suffice, say afford the required dummy pin(s), support the subject plug, and abut the target socket. Also, low-height rearward peripheral walling 19 is shown, but could be higher, see dashed at 23, even abut or joint with a cover, see dashed fragment at 25, that could be an interference or snap or screw or bayonet or other fit using mutually cooperating parts, or use one or mor screws or clips or otherwise require a tool to open.
Figures 4 and 5 further show flanging to at least two opposite sides of an adaptor 110 otherwise similar to what has already been described, see referenced 125A and 125B, actually at tops of shallow rearward peripheral walling.
Figures 6 and 7 also show, for an adaptor 220, further rearward walling closely matching to standard or typical subject plugs, see referenced 227 and including groove formations 229A and 229B for ribbing (see 27A and 27B in Figures 2 and 3). It could, of course, be further the case that the further walling 227 could make interference or snap or other securing fixing directly to or over a subject plug; and/or provided gripping aids (say in the absence of peripheral walling) .
The adaptors 20, 120 and 220 are readily moulded, preferably injection moulded, from a suitable insulating plastics material, i.e. complete with its full-size dummy pin 13 and/or its reduced size dummy pins 17A and 17B and its holes 15A and 125B to receive and pass actual pins 21A and 21B of a subject plug 20 at their insertion therethrough. INDUSTRIAL APPLICABILITY
In use, a subject plug can be inserted in the adaptor at one side thereof, with its actual pins protruding from the other side of the adaptor adjacent reduced size plastics dummy pins. The adaptor can then be inserted in a target electric socket and electrical connection between the socket and the plug made via the actual pins of the subject plug itself. Moreover, feasibly (and if allowed), the adaptor can be inserted first into the target socket ready for later insertion of a subject plug.
