Wire-to-board connector is a kind of electronic connector used to connect wires (Wire) and printed circuit boards (PCB).

It is a key component to realize the transmission of electrical signals or power from the cable to the circuit board, widely used in various types of electronic equipment.

Simply put: “one end is connected to the wire, one end is plugged into the circuit board”, this is the wire to board connector.

Wire-to-board connectors are usually composed of a plastic shell and metal contacts. The metal contacts are responsible for the transmission of electrical signals, while the plastic housing provides insulation.

When a wire is inserted into the connector, the metal contact inside makes tight contact with the wire through a spring or locking mechanism, ensuring a solid connection and electrical performance. This design prevents loose connections or poor contact.

• Wire-to-board connectors are generally available in 2P, 4P, 6P, 8P, 12P and so on;
• Pin spacing is generally 1.25mm, 2.0mm, 2.54mm, 5.08mm, etc..
• Common ways of wire-to-board connectors: pin direct insertion (DIP), SMD (SMT) and so on.

Wire-to-board connectors have a wide range of applications:

• Household appliances: refrigerators, air conditioners, washing machines
• Industrial equipment: PLC controller, industrial sensors
• Automotive electronics: lights, instrument panel
• LED lighting: light strips, driving power supply
• Communication equipment, medical equipment, security systems, etc.

Main advantages of wire-to-board connectors:

• Compact structure, easy to install
• Quick plugging and unplugging, easy replacement and maintenance
• Safe and reliable, high temperature resistance, anti-vibration
• A variety of specifications can be selected to adapt to different occasions
