Modular connectors, jacks included, are networking connections that are used to simply and easily join multiple components together for communication and data transfer. The specific type of jack referenced in this article is the 2178416-1, which is designed to be used for in-line telephone connection on RJ11 and RJ14 registered jacks. In this article, we will dive deeper into two topics: application field and working principles of this jack.

Application Field

The 2178416-1 is primarily used to join two telephone cables together as an in-line connection on RJ11 and RJ14 jacks. This ensures that the same connection and data is being transported through both lines of communication. Because the connection comes with two lines, it is ideal for use with telephones that require both lines for proper operation. The connection consists of four contact points, two for each side of the jack, and is designed to create a reliable connection when both sides are joined.

The 6P4C design of this jack allows the user to use it in a variety of applications. It is particularly effective for connecting two RJ11 or RJ14 jacks, as well as connecting two RJ11 jacks through a consistent modem connection. Additionally, the contact points of this jack are designed to resist corrosion, making it a great choice for outdoor applications.

Working Principles

The four contact points on the 2178416-1 jack are embedded in an insulating plastic shell that securely attaches the jack to the cable. This ensures that the connection will stay in place, while preventing any potential short circuits. The four contact points are coded and each one is responsible for a specific task. The outer and third pins of both sides are used to transfer data, while the inner pins of both sides are responsible for signals that detect if either connection is loose or has been disconnected.

The four contact points are made out of metal and are designed to create a strong connection when the two sides are joined. With the two sides joined, a current flows through both cables and data is transferred. If the connection is loose or disconnected, the inner pins detect this and send a signal that the signal has been disrupted. This works to ensure a secure connection for data transmission and to prevent the loss of any data.

Conclusion

The 2178416-1 jack is an efficient and reliable way to connect two phone lines together. With its corrosion resistant contact points, it is an ideal choice for outdoor applications. Additionally, its 6P4C design allows it to be used for a variety of applications, including connecting two RJ11 or RJ14 jacks through a consistent modem connection. The four contact points are designed to create a strong connection when both sides are joined and to detect loose or disconnected connections.
