Abstract

A connector for an appliance, e.g. a kettle, comprises a casing (10) housing electrical terminals (14, 15,16) and has a transparent or translucent window (21) therein. A lamp (22) is mounted behind the window and is connected between the live and neutral terminals (14, 15) so as to illuminate the window when power is supplied to the connector. Instead of the window the whole casing could be of transparent or translucent material. <IMAGE>

Description

SPECIFICATION A connector for an electrical appliance The invention relates to a connector of the type which is releasably connectible to an electrical appliance for releasably connecting the latter to a mains supply and which is in use connected to one end of a flexible lead, the other end of which is connected to a mains supply or is connectible to a mains supply such as by a plug insertable in, for example, a wall mounted socket.
Such connectors are commonly used with electrical appliances such as inter alia kettles, and coffee percolators.
Handling such connectors with wet hands can be dangerous and could be lethal particularly if the casing of the connector has been cracked by dropping or misuse. When disconnected from the appliance, there is the risk that the connector, when energised, may fall into a sink or washing bowl and this is particularly dangerous if the earth circuit in the home is poor or non-existent.
In accordance with the invention, there is provided a connector of the type hereinbefore described, comprising a casing having at least a part or portion which is transparent or translucent and housing electrical terminals and a lamp arranged so as to be illuminated in use when power is supplied to the connector and so that, when illuminated, light therefrom is visible to a user through the transparent part or portion of the casing.
Preferably, the lamp is a neon lamp.
Preferably, the lamp is connected between live and neutral terminals housed within the casing.
Preferably, a resistor is connected in series with the lamp.
The invention will now be more particularly described, by way of example, with reference to the accompanying drawings, wherein: Figure 1 is a plan view of one embodiment of a connector according to the invention with its cover removed; Figure 2 is a plan view of the connector of Fig. 1 with its cover in place; and Figure 3 is a left hand end view of the connector of Figs. 1 and 2.
Referring to the drawings, the connector shown therein has a casing 10 of moulded plastics material. The casing includes a base part 11 and a removable cover 1 2 fastened to the base part 11 by a screw 1 3. The casing is generally rectangular in plan and houses live, neutral and earth terminals 14, 1 5 and 1 6 respectively aiigned with respective holes 17, 1 8 and 1 9 formed in one end of the casing.
The other end of the casing 10 is adapted to receive one end of a three-core flexible lead 20. Normally, the other end of the lead (not shown) will be connected to a three-pin plug insertable in, for example, a wall mounted socket.
The cover 1 2 has a transparent or translucent window 21 formed such as by a plastics lens, which may be coloured amber or red, fixed in an aperture in the cover; although, the entire cover 1 2 could be made of transparent or translucent material.
A neon lamp 22 is connected electrically in series with a resistor 23 and together the lamp 22 and resistor 23 are electrically connected between the live and neutral terminals 14 and 1 5 respectively. The resistor is covered by a transparent plastics sleeve to prevent the lamp from shorting across two terminals. The neon lamp 22 is mounted in the casing 10 adjacent the window 21 so that when power is supplied to the connector the lamp 22 is illuminated to serve as a warning to a user that the connector is energised and to disconnect the power before handling the connector, by removing the plug from the wall socket or by de-energising the wall socket.
Also, if the appliance fails to work when the neon lamp 22 is energised it will be obvious that the appliance and not the supply is faulty.
In a modification of the above embodiment, the base part 11 and the cover 1 2 are welded together such as by an ultrasonic welding technique.
Alternatively, the cover could be moulded in one piece.
1. A connector of the type described, comprising a casing having at least a part or portion which is transparent or translucent said casing housing electrical terminals and a lamp arranged so as to be illuminated in use when power is supplied to the connector and so that, when illuminated, light therefrom is visible to a user through the transparent part or portion of the casing.
2. The connector of claim 1, wherein the lamp is a neon lamp.
3. The connector of claim 1 or claim 2, wherein the lamp is electrically connected between live and neutral terminals housed within the casing.
4. The connector of claim 3, wherein a resistor is connected in series with the lamp.
5. The connector of claim 4, wherein the resistor is covered by a sleeve of electrically insulating material.
6. The connector of any one of the preceding claims, wherein said part or portion is a transparent or translucent window fixed in an aperture in the casing.
7. The connector of any one of the preceding claims, wherein the casing includes a base part, a removable cover, and live, neutral and earth terminals housed in the casing and aligned with respective holes in one end of the casing, the other end of the casing being adapted to receive a three-core flexible lead.
