Header and IDC (insulation displacement contact) connectors are devices that enable the connection between conductors in electronic devices and electrical circuits.

Header connectors are usually located on the PCB (printed circuit board) and provide connection between the conductors on the PCB. Header connectors can be produced in various shapes and sizes and can be selected to suit different electronic devices and electrical circuits. For example, header connectors on the motherboard of a computer allow connection between other parts of the computer.

IDC connectors are another type of connector used to establish connections between conductors. IDC connectors are used to make connections between conductors by pressing on the conductors, thus establishing a direct connection between the conductors. IDC connectors are generally preferred because the conductors are thick and are used to connect such conductors.
