1-644885-5 Application field and Working Principle

1-644885-5 is a type of rectangular connectors - headers, male pins, especially designed for automotive electronic control system. Unlike the traditional header connectors, 1-644885-5 headers are made of high-density polyethylene with small footprint, which makes them ideal for wiring harnessing in the limited space environment.

Application field

1-644885-5 headers are mainly used in automotive electronic control systems due to their high performance and reliability. The high PIN density suitable for automotive in-line and cluster electronic systems, such as air bag system, electronic stability program, battery control system, engine control system, anti-lock brake system and antiskid brake system. Thanks for its compact size and high density, 1-644885-5 headers are also suitable to be used in the electronic products like cell phone, and a variety of portable electronic equipment.

Working Principle

1-644885-5 headers contain several male pins with tiny metal contacts and have a insulation board. The plastic frame is both injection molded with contact holders and the contacts are inserted into the holders to form a complete header. The correct function of the header starts with a correct connection between the contact and the corresponding receptacle to prevent potential breaks. So contacts should have adequate strength and spring properties to guarantee the reliable connection. Fouling, poor bond, and broken contact could be prevented by adding a small funnels into the headers to guide the contact into the correct position and correct the misaligned position of the contact during the electrical mating. Meanwhile, special material of insulation can make the contact surface self-lubrication and avoid arcing.

Conclusion

1-644885-5 rectangular connectors - headers, male pins have several advantages are suitable for automotive electronic control systems and various industries. The high PIN density connectors are designed with the tiny metal contacts, insulation frame, funnels, and special material. These components play important role in providing reliable connection and preventing potential breaks which make 1-644885-5 headers an ideal choice for wiring harnessing in the limited space environment. Hence, 1-644885-5 headers are widely used in automotive electronic control system and other electronic products.
