Terminal Blocks & Connectors

filter_list

Connectors are components that are manufactured for power, data and audiovisual applications and can be divided into three categories: cable connectors that are permanently attached to the cable, splice connectors that permanently join two lengths of wire or cable and panel connectors which are permanently attached to a piece of equipment so that a cable can be attached to a stationary device.

Terminal blocks are a modular block with an insulated frame connecting two or more wires in a reliable manner. A clamping component and a conducting strip are used to secure and organize connecting wires, allowing multiple outgoing wires to join to one singular incoming wire. Wires are secured to the terminal blocks with screw connections, spring cage connections, push in connections (requiring the use of ferrules on the wires), fast connections, or barrier connections (requiring ring or spade terminals on the wires).

Terminal plugs are a type of terminal block that has a cable entry where the wires are inserted into a housing and has a plug output for easy connection to a socket. This allows for frequent disconnects of main connections without the need to disconnect all individual wires.

FAQs

What are terminal block connectors?

Terminal block connectors are electrical connectors that are used to connect and terminate wires or cables. They are commonly used in electrical installations and control systems, where they provide a convenient and reliable method for connecting and disconnecting wires.

What is a terminal strip?

A terminal strip, also known as a terminal block or connection block, is an electrical component that is used to connect multiple wires together. It typically consists of a plastic or metal strip with a series of metal terminals or screws arranged in a row.

How do terminal blocks connect to Din rail?

Most terminal blocks have spring-loaded clips or other mechanisms that allow them to be easily snapped onto the rail.

 

Terminal Block Basics

Single Level Pass Through Terminal Blocks

Single Level Pass Through Terminal Blocks are used to connect two wires together with a common junction point. This is helpful when a component needs to be disconnected or isolated within a circuit. These are the most common types of terminal blocks in industrial applications. 

Ground Terminal Blocks

Ground Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: they are grounded. These terminal blocks have a metal connection from where the wire is terminated, all the way to the bottom of the block where it will clamp into the panel. This allows for an electrical circuit to be grounded without running a wire to the main ground connection on a breaker or surge protector. 

Fused Terminal Blocks

Fused Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: the presence of a fuse. This fuse provides protection for components from too much voltage or current.

Multilevel Terminal Blocks

Multilevel Terminal Blocks are used to connect two wires together with a common junction point, just like single pass though terminal blocks, but with the advantage of making two electrical connections in the same block. These blocks also incorporate fuses and can be grounded.

Disconnect Terminal Blocks

Disconnect Terminal Blocks are similar to fused blocks, however the disconnect stops the flow of electricity by lifting a lever on the terminal block. Unlike fuse blocks, they are a more permanent solution, but will not provide any protection in the event of a power surge.
