Modular Connectors - Jacks

5558872-1 application field and working principle

Modular connectors, commonly known as jacks, are a type of electrical connector developed for the commercial and industrial markets. They allow the construction of custom-sized electrical equipment, such as switches, terminals, and computer circuit boards, by connecting them through a series of modular plug-and-socket components. Modular connectors are the most popular type of electrical connector used in industry today and have become increasingly significant as a part of the global telecommunications industry. This article will explore the application fields and working principle of 555872-1, a type of modular connector.

Application fields of 555872-1

The 555872-1 is a type of 16-contact modular jack connector designed for use in Ethernet networks. It is commonly used in LAN hardware, such as Ethernet switches, hubs, and patch panels. It is also used in wireless networking equipment, such as access points and wireless routers. The 555872-1 connector is also frequently used in telecom systems, especially in installs that use more than 10 base stations. Additionally, it is often used in digital video systems, such as HDTV set-top boxes.

Working Principle

The 555872-1 modular jack connector is a simple but efficient design which uses the Force-Guided Contact Alignment principle. This type of connector is unique, as it eliminates the use of a second pin for alignment and is capable of holding contact force even during vibration. The five-chamber design of the contact block enables the contacts to have an opposite-side alignment and a unique balance between upward and downward pressure. This design ensures that the connection remains firm even during vibration, thereby providing reliable contact connection and increasing the life span of the plug.

When the modular plug is inserted into the jack, the contact block aligned in the upper section of the connector is inserted into the jack and engages with the fork pins of the contact holder. This engagement creates an internal connection between the two components. As the plug is pushed further into the jack, the contact block continues to move and eventually presses against the contact pads, creating an electrical connection. The contact block also activates a switch that indicates the connection status of the connection.

Conclusion

The 555872-1 modular jack connector is a type of electrical connector which is commonly used in a variety of industries, such as LAN hardware, wireless networking equipment, telecom systems, and digital video systems. It utilizes the Force-Guided Contact Alignment principle to ensure a reliable connection and increase the lifespan of the plug. When the plug is inserted into the jack, the contact block is engaged and creates an electrical connection between the two components. The 555872-1 modular jack connector is a reliable and efficient connector which is popular among many industries.
