Single level pass-through terminal blocks: These are simply used to connect two wires together, i.e.Types of terminal blocks Electrical terminal blocks can be classified on the basis of structure, device type, termination options etc. Terminal blocks keep connections much more secure and wires well organized. That allows us to increase the number of terminals according to the requirements. Most terminal blocks are usually modular and mounted on DIN rail. The body has a mounting arrangement so that the block can be easily mounted on or unmounted from a PCB or a mounting rail. It also provides a base for clamping element. The insulating body of a terminal block houses a current carrying element (a metal strip or terminal bar). A typical simplest terminal block is as shown in the image below. It consists of a clamping component and a conducting strip. Here we use terminal blocks.Ī terminal block (also called as connection terminal or terminal connector) is a modular block with an insulated frame that secures two or more wires together. But what if there are a number wires that need to be joint/connected near each other? Or, what if multiple outgoing wires are to be connected to a single incoming wire? Then this method will neither be safe nor be convenient anymore. But, is it safe? We can apply insulation tape over the joint or use a wire connector. You should do a seal strength test by pulling on the wires after sealing to make sure it is secure and the seal is completed.How do we connect two wires? By stripping the insulation at the ends and twisting them together? Yes, it works. A sealed terminal also acts as a strain relief on the wire connection. The new seal insulates the wires, makes it air tight, and is resistant to moisture and chemicals. By applying heat, the adhesive material begins to shrink and then melts onto the wire, forming a tight seal by keeping the insulation and wires safely encased. When the wire and crimping are set you’ll need to apply heat from a commercial heat gun or paint peeling gun (hair dryers do not have enough BTU) to heat the terminal. You will then crimp the terminal before applying heat. To make wire connections using heat shrink terminals you will need to first prepare the wire and insert all of the copper strands so that they fit into the terminal barrel, making sure you have a perfect fit so that the copper wiring is not exposed. Heat Shrink Terminals are commonly used when a complete seal is necessary for protecting against contamination and moisture. With that in mind, let’s take a look at insulated ring or spade electrical terminals to help determine which one you’ll want to use to fit your need: An electrician would also help you to make a safe electrical connection that can be approved by your local regulatory requirements.

An experienced electrician can help you to better understand how to ensure safety when attaching electrical terminals to exposed wires. A terminal connection must have solid mechanical contact and good electrical contact to work effectively and to prevent damage to the conductors. At Electrical Basics, there are a number of choices from the small and simple electrical connections, to ones that require a strong, sturdy connection for more permanent and hazardous installations.Īn electrical component uses terminals to make electrical wire connections. Since electrical currants and wire sizes vary based on the project, you will need to do some research to find the right one that can handle the electrical load, and protect the wires at its connection point.
Using the right one is important not only for your personal safety, but for ensuring a safe electrical connection at the installation point in a facility, on equipment, and for other home or business applications. There are a variety of electrical terminals you can choose from when you need to do an electrical wiring project.
