4-644627-5 Rectangular Connectors - Headers, Male Pins

Rectangular connectors are essential physical link components, which are widely used in the connections between electronic equipments and wiring harnesses. 4-644627-5 is a rectangular connector which belongs to the series of Headers, Male Pins. This type of connector integrates many characteristics commonly used in head-style connectors, such as seals, strain reliefs, hardware, and grounding fingers. It also offers optional features such as polarization, ribbon cable tapping, rotatable head design, and plugging/unplugging options.

Application Field

4-644627-5 rectangular connectors usually serve as interconnecting devices between circuit boards, cables, and backplane assemblies. Its inherent design ensures its compatibility with a wide variety of cable sizes. As a result, it is often used in backplane and dual inline packages of high-density layouts. Another common application field of this rectangular connector lies in control applications where there is a requirement for reliable performance.

Working Principle

The working principle of 4-644627-5 rectangular connector is very simple. Its design includes two parts- header and male pins. The header is mounted to the chassis or backing card in the device, and the male pins are soldered to the printed circuit board. The male pins include the conductive blades that make contact with the header when it is mated with the housing. The insulated section of the male pins maintains an air gap between them and the housing, which ensures secure separation between circuits and prevents electric shock.

Moreover, this rectangular connector utilizes self-latching pins which prevents the need for secondary locking mechanism. And their retainability allows various lengths of pins and wire insertion without separation. Last but not least, touchproof covers are also implemented in 4-644627-5 series. The aluminum pin cover prevents contact between two current carrying terminals when actuated.

Conclusion

In conclusion, 4-644627-5 rectangular connectors are widely used in many industries. Its common applications and principles are listed above. And due to the fact that many performance characteristics of this connector are identified through the respective system of standards, it is important to check product standards and ratings before purchasing.
