In order to learn the principal of electronic interconnecting parts work.we need to know the basic knowledge of the conductor,When we mentioned that the conductors connect the disconnect parts,In fact,It’s the connector that connect the two parts together,The circuit means the whole electric system,and the conductor is the real road that current flows,Sometimes.You can’t see the actual conductor.Because they are packed by the insulation material or dielectric material.If there is the dielectric material,the conductor can be put in a row and don’t bother each other, Now we’ll introduce some conductors that we usually use:
Discrete wire:The single wire or cable,popular used in many electronic equipment.
Twisted pair:They are consisted of two small wire twisted together.packed with the outer jack.the two wire are in good insulation,the phone cable and the domestic wire are the twisted wire,they are used for computer and telecommunication.
Coaxial cable:They are consisted of the small diameters copper wire packed in the larger diameter jacket,The dielectrics isolate and support them.The insulator material packed in the outside.They are used in the transfer with Video signal transmission,
Tape cable:The name comes from its resemblance to a ribbon,also known as flat cable.they are the parallel conductor covered by the insulator material.The conductor has two forms,One is the circle cross section,the other is the flat flexible cable,They are used for computer and peripheral.
Printed circuit board:The PCB is the copper-coated polymer plate,through the etching processing,print the circuit,they are used for computer and peripheral.
Flat flexible cable and Flat plane circuit(FFC/FPC):They are likely to the tape cable,But the conductor is the flat,not the circle,The conductor cross section is rectangular and extremely thin,They are used for official equipment,security system, communication, vending machine.
Fiber optic cable:the Fiber optic conductor have many series and pattern.But the most common are silica or plastic which is coated by glass, plastic.The light is conducted or transferred by them,They are used in the high speed data transfer and computer networks and communication systems.
