Abstract

A plug is made from two snap-lock parts (one is shown), each having metal plate contacts 13, 14, 15 (13a, 14a, 15a) which sandwich repective wires LW, EW, NW. The parts have corresponding snap-lock devices so that they can be assembled without tools and are colour-coded. The wires may lie in recesses 16, 17, 18 of one part. The other part (not shown) may have protrusions corresponding to the recesses 16, 17, 18 so as to grip the wires.

Description

DESCRIPTION ELECTRICAL SNAP LOCK PLUG The invention is an easy to assemble, snap-together plug, for attachment to small electrical devices, like antique lamps, radios, hairdryers or any other piece of electrical equipment which is not already attached to the manufacturers integrated, bonded plug.
This invention solves the problem of wiring electrical appliances to a new plug.
Conventional plugs have many screws, and different components which require specific tools to assemble. Manual dexterity and nimble fingers are needed to achieve the task. Men sometimes find changing electrical plugs difficult because their hands are too large to manipulate the tiny screws. The wires are often connected incorrectly making the plug dangerous.
A conventional, cumbersome, old-fashioned, electric plug, consists of about 15 different, moveable screws and components. This invention consists of two, snaptogether, moulded parts. The snap-lock device, is colour coded to indicate where the Live, Neutral and Earth wires should be placed making it safer and easier to use.
The invention is a simple moulded Dlastic two Diece appliance comDrising a front
and back section. The plug snaps together like a stronger version of Lego
building blocks once the wires have been positioned.
The snap together process could be likened to a press-stud function, popper beads,
or Legotbuilding bricks. This snap together, though modified process, is the same principle which applies to the invention.
Illustrated are external, internal and side perspectives of the snap plug. It has two moveable parts and plugs into any standard wall socket.
REFER TO DRAWING NUMBER 1 EXTERNAL PERSPECTIVE OF THE SNAP PLUG FIG 1 FRONT SECTION (i) Safety factor - rounded corners on all shapes.
(ii) Unique, colourful, attractive designs, suitable for the children's nursery, or for designer homes.
(iii) Fluorescent colours in non-toxic acrylic paint.
(iv) Different shapes and sizes like triangles, circles, cars, trains, flower shape, frog, heart, or any other simple shape which can be adapted to make a rounded appliance with no sharp angles.
(MW) Main wire connecting the plug to the appliance.
REFER TO DRAWING 2 INTERNAL PERSPECTIVE OF THE SNAP PLUG FIG 2 BACK SECTION 1 - 12 Shows the child-proof snap-lock indents.
13 Metal indented plate on which the exposed neutral wires will connect.
14 Metal indented plate on which the exposed live wire will connect.
15 Metal indented plate on which the exposed earth wire will connect.
16 Indented grove along which the neutral wire will be channelled to connect with the metal plate (13).
17 Indented grove along which the live wire will be channelled to connect with the metal plate (14).
18 Indented grove along which the earth wire will be channelled to connect with the metal plate (15).
MW Main wire connecting the plug to the appliance.
REFER TO DRAWING 3 INTERNAL PERSPECTIVE OF THE SNAP PLUG FIG 3 BACK SECTION OF FIG 1 la-12a Shows the child-proof snap lock extrusion which fits into the corresponding indented snap-lock shown on 1-12 on drawing number 2.
13a Metal extruded plate which fits into the corresponding indented metal plate on 13 drawing number 2. The wire is securely clamped between the indented and projecting metal plates.
14a Metal extruded plate which fits into the corresponding indented metal plate (14) shown on drawing 2.
15a Metal extruded plate which fits into the corresponding indented metal plate (15) shown on drawing 2.
16a Protruding grove that fits into the corresponding indented grove shown on drawing 2, which will securely clamp the neutral wire in position.
17a Protruding grove that fits into the corresponding indented grove (17) shown on drawing 2, which will securely clamp the live wire into position.
1 8a Protruding groove that fits into the corresponding indented groove (18) shown on drawing 2, which will securely clamp the live wire into position.
REFER TO DRAWING 4 SIDE PERSPECTIVE OF THE SNAP PLUG FIG 4 FRONT SECTION OF FIG 2 13 Shows exposed earth wire securely snap locked between metal plates.
14 Shows exposed live wire securely snap locked between metal plates.
15 Shows exposed earth wire securely snap locked between metal plates.
19 Socket Pin for earth connection forms an integral part of indented metal plate Fig 2/13 shown in Drawing 2.
20 Socket Pin for neutral connection forms an integral part of indented metal plate Fig 2/14 shown in Drawing 2.
21 Socket pin for live connection forms an integral part of indented metal plate Fig 2/15 shown in Drawing 2.
