Types of Electrical Connectors

!±8± Types of Electrical Connectors

There are many types of automotive and nautical electrical connectors. Some of the coarse electrical connectors are butt connectors, ring terminals, spade terminals, and quick disconnect connectors.

Butt connectors are used to splice two wires together.

Ring terminals are used to associate the wire to a stud point like a screw for grounding or similar.

Spade terminals can be used like ring terminals but the nice thing about the spade final or fork terminals is that the stud does open to associate to it. The spade can slide nearby the stud for a connection.

Quick disconnect connectors are used to associate to a tab and come in four tab sizes,.110 tab is 1/8 inch,.187 tab is 3/16 inch,.250 tab is 1/4 inch and.375 tab is 3/8 inch. There are male and female quick disconnect connectors the female will slide onto the male tab. Other electrical connectors consist of copper lug ring terminals, crimp caps, t tap connectors, plier tap connectors, hook terminals, and pin terminals.

Electrical connectors can be insulated or non insulated and come in discrete types of insulation. The non insulated electrical connector is ordinarily bare copper that has a tin plating. Insulated terminals can come in Pvc insulated, nylon insulated and heat shrink insulated. The Pvc insulated type are ordinarily the cheapest and most common. Pvc tends to be a harder insulation and can crack when crimped and for this conjecture I do not suggest using them. Nylon insulation is a softer insulation and will not crack when the final is crimped. The nylon insulation will also withstand higher temperatures. I suggest using nylon insulated terminals and connectors. Heat shrink insulated terminals and connectors are great for applications where the final is exposed to outside elements such as high temperatures, rain, snow, and underwater applications.

The heat shrink insulated terminals with adhesive lining originate waterproof connections to the wire. Although heat shrink terminals can be precious they are the best connectors to use since the will last the longest and practically never corrode.

When purchasing electrical connectors it is best to use Ul listed terminals and connectors to make sure you are getting ability connections. I suggest staying away from terminals and connectors that are made in China due to the low ability standards and cheap materials they use to make the connectors. If you search the internet you can find ability terminals and connectors at reasonable prices.
