Definitions

• the present invention relates to the connecting of wires when inserted into receiving units, including electrical pin plugs or other domestic and commercial electrical fittings.
• Plugs and sockets for portable appliances started becoming available in the 1880s, to replace connections to light sockets with easier to use wall-mounted outlets.
• Co-ordination of technical standards has allowed some types of plugs to be used over wide regions to facilitate trade in electrical appliances, and for the convenience of travellers and consumers of imported electrical goods.
• Some multi-standard sockets allow use of several different types of plugs; improvised or unapproved adapters between incompatible sockets and plugs may not provide the full safety and performance of an approved socket and plug combination.
• IEC 60050 refers to these as 'direct plug-in equipment' defined as equipment in which the mains plug forms an integral part of the equipment enclosure so that the equipment is supported by the mains socket-outlet.
• the term 'plug' is used in the sense defined by IEC 60050. Sockets are designed to prevent exposure of bare energised contacts. Sockets may also have protruding exposed contacts, but these are used exclusively for earthing (grounding).
• plug and socket systems often incorporate safety features in addition to the recessed slots or holes of the energized socket. These may include plugs with insulated sleeves, recessed sockets, sockets with blocking shutters, and sockets designed to accept only compatible plugs inserted in the correct orientation.
• the wire is divided and the exposed copper ends or strands are prepared by hand and inserted into ringed holes for each terminal value and the wires are then held using a small screw.
• the screw clamps down onto the copper end of the wire, usually at a midsection area, holding the wire in place.
• the present invention aims to provide a method where the wires that are placed or inserted into a plug or female connection point and held in place using compression and barbed means applied to the end of the wire.
• This method provides a more rapid and instant way of fitting Live, Neutral and also, where applicable, Earth wires into a plug.
• This compression and barbed holding method of wires may also be applied to other inserted wires or cables that would under normal fitting circumstances require additional holding.
• means to hold the wires is provided in the form of additional fixtures which use a narrowing point which are barbed toward the end of the wire which is to be held.
• the narrowing sections are staggered and are provided initially to first insert the contacting end of the wires and narrows at points as the wire passes within.
• a means to hold the end is provided using a method that has barbed or protruding points which grip the wire end and or harness when it is fully inserted, preventing it from being withdrawn.
• the process is detailed when the wire is inserted into a retainer and brass cylinder or barrel as one action.
• the recommended length of exposed bare wire is approximately 1 ⁇ 4".
• the wire is pushed into the brass cylinder until the exposed bare wire contacts the base of the cylinder.
• the cylinder is pushed into the main body which is attached to the component part requiring conducting. As this occurs the cylinder passes through and over the internal wall and protruding rings.
• the pre-folds and cut-outs within the metal work each contribute and act to connect, conduct and secure the wire in place thereto.
• the depth of the base of the cylinder to the first internal ring and pre-cut out/fold is set at 1/8" this results in the wire depth always meeting accurately in the correct position, to be clamped in place. This can also be adjusted to suit various applications by adjusting the depth of the cylinder accordingly.
• the base of the cylinder has a concertina design which acts as a spring to the cylinder, enabling tension to clip into place, via the retainer and also for release of the wire. As the first pre-cut out / fold creates the protruding clamp to hold the wire, it is measured so that the second ring of the component or outer barrel also enables as the brass cylinder, to pass and hold over the first ring.
• the pre-cut out / fold also protrudes and produces teeth between 30 degrees and 45 degree angles down towards the base of the cylinder, which not only grip into the sleeve and hold it very securely but also prevent the pulling out of the wire by the added purchase and resistance in place.
• the last point of this process is the retainer method, where a ring under tension, clips into place holding all components under tension, securing the cylinder in the outer tube or component. By unclipping the retainer, the device releases the clamping of the exposed wire and the sleeve so it can come apart and separate.
• This disclosure provides various features and advantages to the user which include; the elimination of tools for assembly.
• the conduction is guaranteed by the assured measurement of the exposed wire and clamping action each time.
• the conduction is sufficient as the rings and pre-cut outs can encircle the wire never allowing for loss of connection.
• the connection is more secure as the sleeve is also securing the connection.
• the connection is safer as this concept gives two points of securing the wire rather than just one which is currently through just the clamping of the wire by a screw.
• An even further object of the present invention is to provide a new and improved electrical wire holding method which is susceptible of a low cost of manufacture with regard to both materials and labour, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such an electrical wire holding method economically available to the buying public.
• a electrical wire holding method has a wire of cable which is constituted by an insulation sleeve 1 and a copper wire end 2 in the known way. These are inserted into cylinders 4 and 5 and held in a tensioned manner by a retaining clip ring 3, as shown in Figure 1.
• the wire or cable 1 A is inserted into the cylinder 4A and the retaining clip ring 3 is pressed into the accompanying fitting as shown in Figure 2.
• the wire or cable 1B as shown in Figure 3 is inserted into cylinder 4B and held with retaining clip ring 3B, with its copper wire end 2B passing though as shown.
• the fitting being held using pre-cut out folds 7 and 8 which press into the wire adding purchase thereto.
• the end has a concertina embellished opening 6 to help create spring tension upon fitting.
