Conductor (power cord) for household use generally are copper or aluminum core, the appearance of the foreskin wrapped in a layer or layers of insulation, known as the insulated conductor. With this layer of the coat, even if the lamp lit, hand to touch the wire, not shock. According to the conductor (power line) hard and soft cores, the wire was divided into two kinds of hard lines and soft lines. The cord is made of fine copper wire plastic foreskin lines, often moving electrical equipment, such as hanging lamps lamp line for iron, electric rice cookers and power cord. However, in humid places, such as walls, ceilings, use the protection of insulated wires, ordinary insulated wire, sets of steel or plastic casing to avoid decay leakage.
Wire laying method and location, choice of conductor thickness are not the same. Coarse wire used in the stove room and ambient temperature corresponding to those installed in the pipe protection. Buy a new electrical appliances such as lamps, microwave ovens, all with their own power cord and plug may use to pull a wire, in a convenient place to install a wiring board, and still use the thin wire is not used by the ordinary electric light safe. If the microwave power of 1000 watts, 500 watts, washing machine, iron 300 watts with the use of these appliances, the current increased by several times, the use of time and a long, thin wire and a large resistor, the current circulation, can cause fever and burn the wire plastic coat. ?Usually see some wires of the plastic skin is charred black, is the current is too large sake.
Therefore, the home and add appliances, should check the thickness of the original wiring board wire and into the house power cord. Wire is used to protect the wire, to prevent leakage with, do not use wire, wire hanging wires, lights, or wire wrapped around the handles in the wire.

Vacuum cleaners to handheld power cord
Conventional canister-type vacuum cleaners comprise a cord reel assembly for winding a power cord inside the cleaner body. Conventional upright-type vacuum cleaners tend to require a relatively longer power cord, and thus use a cord holderinstead of a cord reel assembly.
During this operation, however, the power cord is often dragged on thesurface being cleaned, and is thus contaminated by impurities and dust. As a result, the user's hands may also become dirty while grasping and winding the power cord. Furthermore, when the user winds the power cord hastily, frictional heat generatedbetween the power cord and the user's hand may hurt the user.
It is to be understood that both the following summary and the detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. Neither the summary nor the description that followsis intended to define or limit the scope of the invention to the particular features mentioned in the summary or in the description.
There is provided a power cord arranging device for a vacuum cleaner, comprising first and second cord grips which are pivotably coupled and moveable between opened and closed positionsabout a hinge member, and have at least two openings configured to receive a power cord when the cord grips are closed, and a resilient member biasing the first and second cord grips closed.
The openings may have a cylindrical shape and may face each other, when the first and second cord grips are closed. In an exemplary embodiment, a pair of pressure levers may be mounted at a position adjacent to thehinge, and a grip handle may be mounted on the first cord grip.
The hinge member may comprise a pair of shaft receptacles mounted on the first and second cord grip, and a hinge shaft mounted so as to be inserted into the shaft receptacles. In an exemplary embodiment, the resilientmember may comprise a torsion spring supported by each of the pressure levers.
In an exemplary embodiment, the openings may comprise a front opening, and a rear opening having a greater diameter than the front opening. Additionally, a guide ring may be mounted on the front opening in order to prevent abrasion.
In an exemplary embodiment, the guide ring may beformed with a greater diameter than the power cord. In an exemplary embodiment, the first and second cord grips may have a section with interlocking teeth of fixed width at one end.

power supply cord set includes a power connector and a power cord
The power supply cord set, however, still has some drawbacks. For example, after the insulating protective layer 22 is sheathed around the connection area between the power cord 21 and the power connector 20, the bare wire portions 211a and 212aare readily contacted with each other and thus a short-circuit problem occurs. In addition, if the power supply cord set 2 has been used for a long period, the internal insulating cover layers 213 and 214 are possibly shrunk toward the distal aperture210a of the external insulating cover layer 210. Under this circumstance, the lengths of the bare wire portions 211a and 212a are increased. Therefore, the possibility of causing the short-circuit problem is increased and the power converter 1 has abreakdown.
Power supply cord sets have been widely used to transmit electricity from power sources or power adapters to power-receiving devices. Generally, a power supply cord set includes a power connector and a power cord. The power connector is fixedonto an end of the power cord and detachably connected to a corresponding electrical connector of an electrical appliance. Through the power supply cord set, electricity can be transmitted from a power source or a power adapter to the electricalappliance.
In accordance with another aspect of the present invention, there is provided a power connector to be coupled with a power cord. The power cord includes a first multi-core wire and a second multi-core wire. The power connector includes a firstconducting element, a second conducting element and an insulating body. The second conducting element includes a first conducting part, which includes a first connecting segment and a second connecting segment.
The insulating body is arranged betweenthe first conducting element and the second conducting element such that the first conducting element is isolated from the second conducting element by the insulating body. The first conducting part of the second conducting element is disposed outsidethe insulating body. The bare wire portion of the first multi-core wire is connected to and fixed on the first conducting element of the power connector. The bare wire portion of the second multi-core wire is connected to and fixed on the firstconnecting segment of the first conducting part of the second conducting element. A terminal part of an internal insulating cover layer of the second multi-core wire is fixed by the second connecting segment.

The power cord includes a first multi-core wire, a second multi-core wireand an external insulating cover layer.
In such a conventional power supply cord, the noise emitted from the receptacle 5 at the power source side to the shielding case 1 is eliminated by the noise filter 6, but a problem remains in that noise emitted outwardly from the shielding case1 through the power supply cord 3 is not eliminated because the cord 3 acts as a radiation antenna.

Information to help you choose the AC power cord
An AC power cord uses alternating electric current which has periodic reversal of directions. It follows strict specifications during manufacturing process, regulating size and shape of wire, and making certain the current and voltage ratings are balanced.
The cords have a male and female ends. The female end attaches to electrical appliances directly while the male connects to an electrical power socket. The cords are designed like all other cords-its plug end indicates different safety features and types.
In polarized electrical cords, there includes a special plug shape to ensure that the electricity flows smoothly along the wires for safety. Its plug end is designed to enter a socket in a one-way only. This guarantees the electrical poles are properly oriented. To make this possible, one plug prong is larger than the other plug. Appliances like blenders and toasters use polarized cords because they do not have internal safety switches.
On the other hand, non-polarized cord plugs are the opposite. The prongs to their plug ends are similar in shape and size. Also, they are designed to plug into the sockets in either way. Such is possible because the neutral and live wires are connected in random. Non-polarized cords are connected to have a shut off and polarity-shifting features. They have heavier insulation surrounding the wires than do polarized cords.
Meanwhile, the grounded cords are a combination of both the polarized and non-polarized. They have plug ends of polarized and non-polarized. It features a third prong or a grounding rod to divert the stray voltage into the ground, away from users and the equipment from which the cord is connected. Thus, the grounded AC power cord is the highest-rated for safety. It is seen in all equipment or appliances that draw huge quantity of electricity to operate or any devices that have sensitive electronic circuitry needing more safety.
Primarily manufactured from thin copper wire enclosed in an insulating plastic and rubber, AC cords have prong contacts made of either brass or steel and plated with zinc, tin, or nickel. They are used for retail, electronic, commercial, industrial, and residential applications. They are commonly seen in computers, laptops, household appliances, power tools, and lighting.
The first power cords were hardwired to Edison lamp holders. They were used both for household or industrial equipment or lighting. Harvey Hubbell was the inventors of two-prong electrical cord and plug. His designed was adopted into widespread use since. The three-prong grounded cords and polarized cords were invented later to incorporate greater safety in electrical equipment.
AC power cords are connected to plugs and sockets to connect an electrically-operated device to a power supply. To reduce the risk of injury or death by electric shock, there are plugs and socket systems that incorporate different safety features. The sockets are designed to accept matching plugs only and reject all others.
