Terminal blocks are used in almost any electrical panel assembly to connect field wiring to a control system or regulator. Inherently, they exist as a reliable, secure and robust connection which ensures that the transfer of electricity and/or signal remains unchanged over its working lifetime. The main components of terminal blocks are headers, plugs, and sockets.

Headers are the backbone of terminal block assemblies and provide the interface between the field wiring and the internal control system. Made up of a printed circuit board (PCB) with a unique slot pattern on the top surface, headers provide the biggest diversity of connection optimization. The slot pattern is designed to accept multiple sets of contacts – such as single and double row headers with either horizontal, vertical, or right angle socket contacts, depending on the application requirements.

Plugs are the mating counterparts of headers that provide the physical connection to the control system. They are inserted into the header slot pattern, which serves to secure the field wiring as well as provide electrical connection between the incoming field wiring and the active control system. Plugs can also be found in either single or multiple rows, depending on the number of field wires required to be connected.

Sockets, also referred to as jumpers, link the internal control system to the various connections at the header. These are specially designed plastic pins that are snapped into the header slot pattern, thus linking the internal control system to the incoming field wiring. In order to ensure electrical continuity within the system, multiple sockets can be found in most terminal block assemblies.

14110313002000 is an example of a terminal block assembly used in a variety of industrial control and automation applications. It has a double row header, with 13 horizontal pins on each row, making it a 26-position, single-level block. This type of header is great for connecting incoming field wiring to multiple internal circuits and controllers. It also features 3.5mm of right angle socket contacts and a 10A rating, making it suitable for low to medium voltage applications.

The working principle of 14110313002000 is fairly simple. First, the field wires are placed into the plug and then secured by tightening the two screws located on either side of the plug. The plug is then inserted into the double-row header, allowing the field wiring to now make contact with the printed circuit board (PCB) within the header. Next, the sockets are snapped into the header slot pattern in order to electrically connect the incoming field wiring to the internal control system. In a typical system, each socket is responsible for connecting two different circuits to each other.

In conclusion, terminal blocks – headers, plugs, and sockets – are an integral part of any electrical system, allowing the transfer of electricity and/or signal to remain unchanged over its working lifetime while also ensuring a reliable and secure connection between field wiring and the internal control system. The 14110313002000 terminal block assembly is an example of a popular model and its working principle is relatively simple.
