Rectangular Connectors - Headers, Male Pins, 87551-8 Application Field and Working Principle

Rectangular connectors, including headers, female sockets, and male pins, are one of the most commonly used types of electrical components. They are often used to connect components inside an electronic device to each other or to provide an external connection point for the user. The 87551-8 is an example of a popular rectangular connector. This article focuses on the application field and working principle of the 87551-8.

Application Field of 87551-8

The 87551-8 is mainly used in computer, communication, consumer electronics, and automotive fields. It is most commonly used in applications where a low-current connection is required, such as for signal and power connections of electric and non-electric products. In computers, the 87551-8 is often used as a connector for the computer’s mainboard to the processor, memory, and/or other I/O devices. In consumer electronic products, they are used as contacts for connection of the screen to the main board, and as a power supply and/or signal connection for different components of audio, video and other equipment. In automotive applications, these connectors can be used as part of a car’s wiring harness, for both power and signal connections, and for connection of actuators and other in-vehicle components. The 87551-8 is also well suited for industrial automation and many other fields.

Working Principle of 87551-8

The 87551-8 is a type of right angle-type header and male pin combination. A rectangular connector consists of two parts: a male pin and a female socket. The male pins are inserted into the female socket and make contact with the metalized contacts on the socket. The technique used to make the contact is called EMC, which stands for electrical and mechanical contact. In this technique, the female socket is designed with protrusion to create an EMC contact between the male pin and the metalized contacts. This EMC contact is extremely reliable, providing low electrical resistance and excellent current efficiency, thus ensuring that the device’s electrical connections are reliable and strong. The 87551-8 connector uses a two-part latch design to ensure a secure connection and prevent accidental disconnection.

Conclusion

The 87551-8 rectangular connector is a popular choice for many low-current connection applications in various fields. It is most commonly used in computer, communication, consumer electronics, and automotive applications. The 87551-8 is a two-part right-angle header and male pin combination, which makes contact with metalized contacts using the EMC technique to ensure a reliable connection. It also employs a two-part latch design to ensure a secure connection and prevent accidental disconnection.
