Electrical Terminals: What Are They For?
power cables and conductors. This little device is extremely versatile and is
available in different sizes and formats.
How electrical terminals work:
Electrical terminals are made of electrically conductive material such as copper tinned or brass. Also, they may or may not have insulation. There are terminals for electrical appliances of various models and sizes. Some can be found insulated or non insulated based on your needs. However, not only are there differences between sizes and models, as it is also common to notice the variation of colors, where each color represents a type of gauge to which the terminal best suits.
Eye / Ring Terminal
This terminal model is ideal for applications where it is necessary to ensure that the conductor won't come off. This is the most secure type of terminal as it remains fully secured. To remove it, it is necessary to remove the screw completely.
To connect the terminal already applied to the conductor with the crimping tool, just insert the screw through the hole in the tongue.
In addition, this terminal model is available for wire gauges from 0.25 to 35 mm2.
Fork Terminal
This terminal is known as a fork, due to its format that has an opening that provides quick installation and ease of fixation on the surface where it will be installed.
Since it is not necessary to completely remove screws in maintenance/installation in this terminal, it is used on terminal strips. As with the Olhal model, the indication for installing the electrical terminal fork can also be made through crimping tool
Pin Terminal
Because of their ease of connection, pin terminals are indicated to use in
terminal strips, contactors and as a flexible cable termination.
Single and Double Tubular Pin Terminal or Eyelet Terminal
This type of terminal is recommended for connecting electrical conductors in installations where dimensions are reduced and resistance to vibrations is required.
Isolated Male and Female Terminal
Made of brass with PVC insulation, the terminals are indicated to be used together in connecting electrical conductors. The male and female terminals fit easily and quickly forming a coupling disconnectable. The male terminal has a tab that slides into the female terminal with great fixation due to the locks and fitting edges existing in the female terminal.
Since they are disconnectable, these terminals are commonly used at points in the installation where disconnection for maintenance is foreseen. Fully insulated male and female terminals ensure greater efficiency, lower short circuit risks and increase safety.
As with other types of terminals, it is recommended to use crimping tools for its application.
One Hole Lug Compression Connector
These terminals are resistant to corrosion and, as they remain completely fixed by screws, this model is considered very safe.
Because they are more robust, this terminal is used to connect components of larger electrical circuits, such as molded case circuit breakers.
Solderstick has a set of the best quality ring/grommet connectors for your installation.
The thick copper barrel ensures a secure and strong crimp every time, providing minimal voltage drop, high current flow and less heat. This will prevent short circuits and problematic wiring that inferior connectors are known for.
Being easy to use, the insulation piping has a unique double wall design.
High quality 3:1 shrink tube features a heat activated sealant coating
to provide a 360 degree secure seal.
It is flame retardant, waterproof and can be used underground.
