Backplane connectors, also referred to as bus connectors, are a type of electrical connector designed to enable different types of electrical devices to connect to one another in a system. Among their various designs and applications, one of the most popular backplane connectors is the 179317-2. Its application field and working principle are illustrated in this article.

Application Field

179317-2 backplane connectors are used in a wide variety of situations. This type of connector is well-suited to high-speed, low-profile applications in cable-to-cable and cable-to-board configurations with harsh environment components. It is most commonly used in industrial automation systems, communications networks, automotive and military technology, power distribution, aerospace, and medical equipments.

Working Principle

The basic working principle of the 179317-2 backplane connectors is that the female connectors incorporate small blades which make contact with the mating pin. The blade is surrounded by a spring that allows it to be pushed in and out of the socket-like receptacle. The forces exerted by the spring on the blade ensure that levels of electrical contact between the two connectors can be maintained. This reliable contact is further enhanced through the use of the preloaded fixings which secure the blade and the receptacle.

These backplane connectors use four types of contact: two power contacts and two signal contacts, providing robust mechanical connections and electrical conductivity. The two power contacts give the connection two levels of voltage, while the signal contacts are used to transfer information between the two connected devices. The contacts are galvanically isolated from one another by means of a plastic housing, meaning that the various levels of voltage across the connection will not interfere with one another. Additionally, the housing also serves to protect the connectors from the external environment.

Advantages

Due to its robust design, the 179317-2 backplane connector is particularly suitable for high-current density applications. The contact layout ensures a reliable connection which can withstand shock, vibration and extreme temperatures. The use of the preloaded fixings further increases the secure connection while reducing insertion force.

In terms of cost-effectiveness, the 179317-2 connectors are one of the most economical options available on the market, and their lifecycle is considerably long. Moreover, the connectors are capable of transmitting data at high speeds, making them suitable for high-speed transmission systems.

Disadvantages

Despite its numerous advantages, the 179317-2 backplane connectors do have some drawbacks which should be taken into account. Firstly, the connector\'s size is relatively large and this can limit its application in small spaces. Additionally, the connector\'s insertion force can be high, especially when compared to other types of connectors such as the USB connector.

Conclusion

The 179317-2 backplane connectors are a highly reliable and cost-effective solution for a wide range of applications. Despite its few downsides, the 179317-2 is one of the most popular and sought-after connector designs on the market today, making it the ideal choice for a vast number of applications.
