Introduction

Rectangular connectors, also known as headers, are a type of electrical connector which have pins or blades for the purpose of connecting two or more signals, power or a combination of both. In this article, we will discuss the application field and working principle of the HIF3FB-40DA-2.54DSA(71) connector.

Application Field

The HIF3FB-40DA-2.54DSA(71) connector is designed to be used for applications in the computer, consumer electronics and consumer medical fields. It is mainly used for data transmission and signal connectivity.The HIF3FB-40DA-2.54DSA(71) connector has a high density 40 pin array configuration which allows for a very small profile and helps optimize board space while still providing reliable operational performance. It is also designed with a low profile design which reduces overall system risk when used in low-profile boards. This connector offers a wide range of current handling abilities, has very high durabilities, and outstanding EMI/RFI performance due to its high signal-to-noise ratio.

Working Principle

The HIF3FB-40DA-2.54DSA(71) connector\'s design makes use of a friction lock system, which can ensure an extremely secure and reliable connection. The contact retention system works on two principles: a vertical retention force and a horizontal alignment force. The vertical force is provided by two sets of pins that slide into retaining slots of the connector receptacle. The horizontal force is provided by a series of V-shaped detent style contact pins and cavities. These small V-shaped indentations fit tight together and create a friction force, helping to lock the cable or integrated assembly into the receptacle housing.The HIF3FB-40DA-2.54DSA(71) connector also features a spin-locks system that provides additional cable durability and improved working life. The spin-locks system helps to reduce the number of times a connection needs to be refastened, thus improving the overall life expectancy of the product.

Conclusion

The HIF3FB-40DA-2.54DSA(71) connector is a reliable and secure connection solution for a variety of applications. With its high density, low profile design, and reliable friction-lock system, it is well-suited for computer, consumer electronics and consumer medical applications. The spin- locks system of the connector provides additional cable durability and improved working life, making it a great choice for long-term use.
