Module three: Core Electrician's Tools
Types of Crimp Connectors
Flat Blade Terminals
These are typically used where the wire is going to be attached using a nut and bolt or a screw.
Ideal for inserting the ends into a terminal block that uses a screw to secure the connection.
These can be used to slip under the head of a flat headed terminal screw before it’s tightened down.
Splices (Butt and Parallel)
A butt splice has an internal stop for the wire half way through, whereas a parallel splice doesn’t. They are both used for permanent wire joints.
These are a compact flat blade crimp connector that fit in small screw terminal blocks; frequently found in electronic circuitry.
A version of the spade terminals that lets 3 wires be joined and un-joined
Female/male push on
These are used to make joints that can be taken apart. Unless an additional sleeve is used they are not fully insulated and are most likely be used on low voltage DC control circuitry.
Boot Lace Ferrules
Boot lace ferrules are crimp connectors that slip over the end of multi-strand wire. The nose of the ferrule is then crimped on to the wire. This makes the end of the wire perfectly suited to be inserted into a terminal and screwed down.
Now that you know about the different types of crimps, its worth finding out about the different types of Crimping pliers.
