Rectangular Connectors - Headers, Male Pins – 171457-4 application field and working principle
Rectangular connectors are commonly found in electronic, electrical and communications systems, and the 171457-4 connector is the most widely used variety of this type of connector. Its uses vary greatly, but it is mainly used for harnessing and terminating multiple conductors of the same or different types.
The 171457-4, commonly referred to as a ‘pin header’, is a soldering or crimping type, male pin connector with two rows of straight (vertical) 4.2mm spaced pins. This type of connector is designed to withstand frequent reuse and can easily be used with a wide range of cable sizes and materials.
The most common application of the 171457-4 connector is in the field of computer and communications devices. As Ethernet-based devices and computers have grown in popularity, so too has the demand for high-quality, reliable pin header connectors. The 171457-4 connector is an ideal choice for these applications due to its ability to handle high-speed data transmission and its relatively easy and cost-effective assembly.
171457-4 connectors are ideal for connecting devices that require an open termination type connection such as USB 3.0 or other computer peripheral connections. The two rows of pins make it easier to connect than other rectangular connectors like the 171454-4 connector which requires additional copper strips. It is also suitable for applications where multiple signals need to be distributed, such as larger scale broadcasting applications.
In terms of working principle, the 171457-4 is simple to operate. It consists of two rows of male pins which are inserted into the female socket of the 171457-4 connectors. When the two rows of pins are aligned correctly, electrical current is conducted through the pins to the corresponding female contact, completing a circuit. This circuit is used to transfer data, power or control signals between two devices.
To ensure reliable operation, all of the pins must be properly aligned and the contact force must be monitored. The contacts must provide the necessary amount of contact force without overstressing the pins. Proper contact force ensures that the connection is strong and dependable for many uses.
The 171457-4 connector is an easy to use and reliable way to connect multiple devices together for any data transmission or power transmitting application. Its simple design and effective operation make it ideal for applications in many fields, from computer peripherals to broadcasting.
