Spring Connector is a type of connector or terminal assembly with an internal spring structure, which achieves electrical connection through the spring mechanism.

Core Components of Spring Connector:

• Plunger: Contacts the target terminal and conducts current. Usually gold-plated to ensure conductivity and corrosion resistance.
• Spring: Provides stable contact force, allows axial movement of the plunger, and ensures reliable connection.
• Barrel: Encloses the spring and guides the plunger movement, ensuring structural stability and a complete conductive path.
• Housing: Fixes the pin components, maintains pin alignment, and offers heat resistance and flame-retardant properties.
• Tail: Connects to the PCB or wiring harness, available in Surface Mount (SMT), Through-Hole (DIP), or Crimp Terminal formats.

Main Advantages of Spring Connector:

• High reliability contact performance:Utilizes spring-loaded contacts to provide consistent and stable contact pressure, effectively preventing poor contact caused by vibration, thermal expansion, and other factors.
• Excellent vibration and shock resistance:The spring structure offers cushioning characteristics, making it suitable for high-vibration and high-shock environments such as automotive and industrial harnesses, ensuring connection stability.
• High assembly flexibility:Has certain floating compensation capability, allowing slight displacement and tolerance during mating, reducing alignment difficulty during assembly.
• Compact size, space-saving:Small and lightweight design meets the requirements for compactness and lightness in modern wiring systems.
• Supports high mating cycles:Spring connectors are designed for frequent insertion and removal, suitable for modular and maintenance-intensive applications.
• Strong customization capability:Can be flexibly customized based on electrical performance, pin layout, and mechanical dimensions to meet various wiring connection requirements.
