There are lots of varieties of automotive and marine electrical connectors. A number of the common electrical connectors are butt connectors, ring terminals, spade terminals, and quick disconnect connectors.

Butt connectors are utilized to splice two wires together.

Ring terminals are employed to connect the wire to some stud point just like a screw for grounding or similar.

Spade terminals can be used like ring terminals however the nice thing about the spade terminal or fork terminals could be that the stud does offered to hook up with it. The spade slip round the stud for the connection.

Quick disconnect connectors are employed to hook up to a tab and are avalable 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. You’ll find male and female quick disconnect connectors the woman will slide on the male tab. Other electrical connectors include copper lug ring terminals, crimp caps, t tap connectors, plier tap connectors, hook terminals, and pin terminals.

Electrical connectors might be insulated or non insulated and are avalable in various varieties of insulation. The non insulated electrical connector is generally bare copper which has a tin plating. Insulated terminals comes in PVC insulated, nylon insulated and also heat shrink insulated. The PVC insulated type are usually the cheapest and most common. PVC is commonly a harder insulation which enable it to crack when crimped and consequently I wouldn’t recommend with them. Furukawa Sumitomo Connectors is a softer insulation will not crack if the terminal is crimped. The nylon insulation will even withstand higher temperatures. I would recommend using nylon insulated terminals and connectors. Heat shrink insulated terminals and connectors are perfect for applications where the terminal is exposed to outside elements like high temperatures, rain, snow, and underwater applications.

The heat shrink insulated terminals with adhesive lining create waterproof connections for the wire. Although heat shrink terminals can be costly these are best connectors to work with since will last a long and almost never corrode.

When choosing electrical connectors it’s best to use UL listed terminals and connectors to ensure that you are receiving quality connections. I recommend steering clear of terminals and connectors which are manufactured in China as a result of low quality standards and economical materials they will use to help make the connectors. If you browse the internet you’ll find quality terminals and connectors at inexpensive price points.
