The QZ000371 series of Press-Fit connectors is a component that utilises the advanced Press-Fit connection technology, which innovatively uses flexible or rigid pins to form a tight, solder-free, direct electrical connection with metallised through-holes on the PCB board.

Thanks to its unique design concept and excellent connection stability, the QZ000371 series is widely used in many key areas such as automotive electronics, communication technology and new energy sources. The pin structure, specifications and materials used have been carefully considered and optimised to create a robust and reliable contact interface during the crimping process, ensuring that the product meets high standards of reliability and durability.

Further, this series of connectors demonstrates excellent ease of use, with quick and easy installation and reduced subsequent maintenance costs, making it the preferred solution for many electronic equipment manufacturers.

Overall, the QZ000371 series of crimp pin headers not only meets the stringent requirements of complex electronic systems for connectivity, but also stands out in the industry for its practicality and affordability.


  • Solder-free process

The connector is connected to the PCB board by mechanical crimping without soldering, thus avoiding thermal stress, solder cracks and other problems that may arise during the soldering process, simplifying the production process and improving production efficiency.

  • High reliability

Press-Fit technology forms a stable and reliable electrical connection through the fit of precision-designed pins and metallised holes in the PCB board. With low contact impedance, this connection provides excellent conductivity and signal integrity, enhancing the long-term reliability and stability of electronic systems.

  • Easy to install and maintain

Due to the solderless design, the QZ000371 series connectors are easier and faster to install and maintain. When components need to be replaced or upgraded, the connectors can be easily removed and replaced, reducing downtime and maintenance costs.

  • Environmentally Friendly

Compared to traditional soldering methods, Press-Fit technology avoids the use of solder, especially hazardous substances such as lead-based solder, which is in line with the globally driven environmental protection trend and helps reduce environmental pollution during the production of electronic products.

  • High Density Designs

Press-Fit technology allows for higher density PCB designs as the pressure contacts take up very little space on the PCB. This helps to achieve more compact component configurations and higher wiring densities in limited space, especially for space-constrained application scenarios such as mobile devices, aerospace systems and automotive electronics.
