Types of Electrical Connectors

There are numerous kinds of marine and automotive electrical adapters. Some of the typical electrical connectors are butt adapters, ring terminals, spade terminals, and quick detach connectors.

Butt adapters are used to splice 2 wires together.

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

Spade terminals can be utilized like ring terminals but the great thing about the spade terminal or fork terminals is that the stud does open to link to it. The spade can slide around the stud for a connection.

Quick detach adapters are used to link to a tab and come in 4 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 detach connectors the woman will move onto the male tab. Other electrical ports consist of copper lug ring terminals, crimp caps, t tap connectors, plier tap ports, hook terminals, and pin terminals.

Insulated terminals can come in PVC insulated, nylon butt connectors insulated and heat shrink insulated. I suggest utilizing nylon insulated ports and terminals. Heat shrink insulated terminals and adapters are fantastic for applications where the terminal is exposed to outdoors components such as high temperatures, rain, snow, and underwater applications.

The heat diminish insulated terminals with adhesive lining produce water resistant connections to the wire. Although heat diminish terminals can be costly they are the best connectors to use because the will last the longest and practically never corrode.

When acquiring electrical adapters it is best to utilize UL noted ports and terminals to make sure you are getting quality connections. I advise keeping away from terminals and connectors that are made in China due to the low quality standards and cheap materials they use to make the ports. If you browse the web you can find quality terminals and connectors at sensible costs.
