Terminal Blocks - Headers, Plugs and Sockets

A terminal block - header, plug or socket - is a device widely used in electric circuits for the distribution of power and signals. Provided with the EDZ1550/16, a 3.5mm pitch terminal block header, this plug is suitable for both DIN rail-mount applications and non-DIN rail mounting. Its various uses, along with its working principle and other properties, are summarised here.

Application Field

The EDZ1550/16 terminal block range is designed for use in a wide range of industrial and consumer electronic products. It can be used in data interface cards, communications-equipment, base stations, satellite TV equipment, medical equipment, aerospace applications and many other electronic applications. It is suitable for any kind of connection requiring high-current handling, such as those used for AC and DC power distribution, control systems, and other signal transmission.

These headers provide a secure, reliable connection in a wide range of applications, and are ideal for quick and easy assembly, as their easy-to-assemble design and straightforward compatibility with mating parts allow for fast installation and low cost.

Working Principle

The EDZ1550/16 terminal blocks are designed to provide a secure connection of two electrical circuits in a holder or terminal strip. All of the headers feature a screwed-on terminal block, and the EDZ1550/16 are designed for 3.5mm pitch use. The connection is made via a pitch-number specific plug inserted into the header, which subsequently made contact with the circuitry within the header.

The plug is held in place by a threaded terminal insert, which uses a thread system to ensure an secure connection. It fits into a counter bore found at the tip of the plug and is tightened in place once the plug is inserted. The locking is done by the plug’s internal threaded design, making it more secure than other connection systems.

The EDZ1550/16 features a wide variety of plug options which provide further options with regards to locking pins, terminals and wire-termination. A wide range of accessories are available for the EDZ1550/16, making it an ideal choice for any application.

Advantages

The biggest advantage of EDZ1550/16 terminal blocks is their versatility. They are designed to fit a wide range of applications, from consumer electronics to industrial applications. They are also highly reliable, with a secure fit and strong locking system which ensures that a secure electrical connection is established each time the plug is inserted.

Other advantages of EDZ1550/16 include their compact design and their ease of installation. With their low-cost assembly, the block header can be fitted quickly to any circuit board, and the plug is designed to be plugged in without the use of additional hardware.

Disadvantages

The main disadvantage of EDZ1550/16 terminal blocks is that they are not suitable for all applications. As the terminals are only compatible with 3.5mm pitch plugs, they are not suitable for use with other devices. Additionally, the threaded terminal design means that the terminal blocks are not suitable for applications that require frequent reconfigurations, tight space applications, or in applications where wires are frequently changed.

That being said, it is important to note that these drawbacks can be easily overcome with the proper insertion of plug adaptors, plugs with alternative fitting threads, or by using additional securing mechanisms.
