Terminal Blocks - Barrier Blocks

0387291405 barriers are a type of terminal blocks, used to provide insulation between high and low power. The main components are an insulating block and two or more metal terminal contacts, connected to the block. The contacts are designed to fit into different types of sockets, including blade, wire, screw or solder type. The purpose of the terminal blocks is to secure the connection between wires and other electrical components, without risk of shorts or sparks.

Barrier blocks are typically used in applications where multiple devices require a higher voltage rating and need to be insulated from each other in order to protect the devices. They are also used when there is a need to wire multiple connections into a single terminal or for high voltage applications, such as motor control, where multiple connections need to be connected to a control system.

The construction of barrier blocks consists of a few components; a base plate, a contact body, insulation blocks, contact plates and contacts. The base plate acts as a heat sink, dissipating heat generated during operations. This ensures that the contacts maintain their mechanical strength over time. The contact body is the main body of the terminal block, and acts as the mounting point for the contacts. The insulation blocks provide insulation between the contact plates and the contact body. The contact plates provide openings for the wires to be connected to the contacts, and the contacts themselves are the actual electrical contacts. These are typically made from copper or brass, and have a large contact surface area.

The operation of barrier blocks is relatively simple; the contacts are designed to fit into the respective sockets, then the wires are connected to the contacts. When the two contacts come into contact, the current is able to flow between the two, providing a secure connection. The insulation blocks provide additional insulation between the lower and higher voltage connections, ensuring the current can flow without risk of sparking or shorting.

Barrier blocks are an essential part of many electronic circuits, being used in the automotive, industrial, consumer electronics and medical device industries. With the ability to securely link devices at different power levels, their use is expected to increase in the future.
