Terminal blocks are used in various industries to ensure electrical connections are made safely and securely. The term \'terminal block\' is used to describe a range of modular electrical components which typically consist of either a panel or board mounted terminal head with a series of terminal sockets which enable the conductor of a wiring system to be connected to the connectors. Generally, there are three main types of terminal blocks, headers, plugs and sockets, and 1706246 application field and working principle is the focus of this article.

Headers

Headers are available in two typical designs; straight or right angle. The type used is solely dependent on the application, whether it is being used in a vertical plane such as for DIN rail mounting, or in a horizontal plane, for example in panel mounted applications. These are used most commonly to interconnect modules or printed circuit boards.

Straight headers, as the name would suggest, are used for connections in a straight line. For example, due to the smaller form factor and single row of connectors you could make a line-up of card-edge plug and socket connectors. This could then interface with another PCB board so that an array of conduits can be arranged on the same system. The connection at the other end of the cable could be terminated with a simple plug or socket.

Right angle headers, on the other hand, are used to make connections at an angle. This allows the formation of two separate vertical planes of conductors. The overall connection is made much easier and more streamlined due to the angled orientation, as all components can sit flush against the side of the equipment, thus saving space.

Plugs & Sockets

Plugs and sockets are specialised connectors used to make electrical connections. They are composed of a metal or plastic body that houses the connective pins and contacts to establish a secure connection between two devices. Plugs are usually mounted within a terminal block or panel and sockets mounted to the device itself, such as a PC board or cabinet.

They can be used in two ways, either \'one-to-one\' to interconnect devices or for \'one-to-many\' applications, used to branch multiple devices onto a single source. Plug and sockets offer a more reliable connection than headers, due to their more sophisticated locking mechanism, and can be used in hundreds of different applications, reducing downtime and maintenance.

1706246 Application Field and Working Principle

1706246 terminal blocks, plugs and sockets are designed for applications in industries such as industrial automation, automotive, and telecommunications where reliable and durable connections are required. It is constructed of a thermoplastic housing that features a \'finger proof\' design, making it suitable for applications with minimal space. This terminal block has a voltage rating of 18-32 VAC or VDC and 12 - 26 AWG wire.

The 1706246 terminal block features a unique friction type connection system that requires no screws and provides a clean and reliable connection. The connection system utilises a combination of clamping forces which secure the conductors in place when pressed against the contact. This ensures an improved electrical performance, more efficient connection and improved current flow.

The push-in terminal pins adopt a spring held device which is activated by inserting the conductor. This automated process is very simple and reliable, minimising installation time. The built in insulation ensures a safe and secure connection in most environments, saving installation costs and reducing the possibility of electrical problems in the long run.

Conclusion

Terminal blocks are used for a variety of purposes in different industries, and the 1706246 terminal block is particularly designed for reliable and durable connections. It features a unique friction connection system which is both simple and secure, providing improved electrical performance and efficient connection. By using this terminal block, users can not only save time but also reduce the possibility of electrical problems which could cost them significant amounts of money.
