Electrically connected components of an electrical circuit are those that allow an electric current to flow between them via an electrical conductor. An Electrical Connector is an electromechanical device that connects segments of an electrical circuit or different electrical circuits, forming a larger circuit. The connection can be removable (as with portable equipment), need a tool to assemble and disassemble, or function as a permanent electrical union between two points. Most Electrical Connectors are gendered, meaning that the male component, known as a plug, attaches to the female component, or socket. In addition to the categories listed above, connectors are distinguished by their pinout, method of connection, materials, size, contact resistance, insulation, mechanical durability, ingress protection, lifetime (number of cycles), and ease of use.
A connector should be visually identifiable, quick to assemble, affordable, and need minimal tooling. Connectors make it possible to connect wires, cables, printed circuit boards, and electronic components. Our many connector types, including PCB connectors and wire connectors, are designed to reduce application size and power consumption while increasing performance.

Electrical Connectors are made of two types of materials: conductors and insulators. Contact resistance, conductivity, mechanical strength, formability, and resilience are all key properties of conductor materials. Insulators must have high electrical resistance, withstand high temperatures, and be easy to produce for a precise fit.
Copper alloys are commonly used as electrodes in connectors due to their high conductivity and malleability. Phosphor bronze, beryllium copper, and brass are a few substitutes. A common covering for the base electrode metal is an inert metal, like tin, nickel, or gold The application of coating material with high conductivity, mechanical toughness, and corrosion resistance serves to mitigate the effects of passivating oxide layers and surface adsorbates, which limit metal-to-metal contact patches and contribute to contact resistance.
Board-to-Board connections: Board-to-board connectors are used to connect PCBs that do not require a wire. The board-to-board connectors can reduce space on cables, making them ideal for systems with limited space. Connectors can be used to connect the PCBs in either parallel or perpendicular form. However, the phrase is also used to designate perpendicular or side-by-side PCB configurations. These arrangements are commonly used for motherboard-daughterboard configurations, with an emphasis on the parallel arrangement.
Connectors for Wires and Cables: As the name suggests, wire-to-wire connections link two wires. One of the connector's ends is permanently linked to the wire. The connector's opposite end forms a separate interface. Crimping or insulation displacement contact (IDC) can be used to create a permanent connection. The IDC method involves inserting an insulated wire into a slot of a sharpened metal beam to make a connection. The hard metal-to-metal contact that forms between the wire and the beam is caused by the sharp edges of the beam slicing through the insulation.
Wire/cable-to-board connectors: A wire-to-board connector connects a wire or cable to a printed circuit board (PCB). The wire connections are comparable to those used for wire-to-wire connections, while the board connections are mostly press-in or soldered two-piece connectors, with some card edge variants still in use. The mating interface for the detachable connection could be identical to that of a wire-to-wire connector from the same product series. While wire-to-board connectors have many applications, the tendency is to use cable-to-board connectors, or cable assemblies, to reap the benefits of IDC.
