Quick Connects are a product that are known by a few different names.
They are known as quick connects, disconnects, Fastons and even just as tabs.
Often times you will see this type of termination on relays or other heavy duty applications that require a fair amount of current. They also provide easy connecting and disconnecting which is why they have their name.
Once a wire is terminated to either a male or female quick connect they can either be terminated directly to each other or they can be inserted into connector housings so that many of them can be terminated at the same time and not touch each other.
Often times you will see this combination in automotive applications, as well as, industrial applications where ease of use and higher voltage and current may be in use.
We have many examples of both the terminals as well as the housings.
