Forms of Electrical Connectors

There are many varieties of automotive and marine electrical connectors. Some of the common electrical connectors are butt connectors, ring terminals, spade terminals, and quick disconnect connectors.

Butt connectors are widely-used to splice two wires together.

Ring terminals are widely-used to connect the wire into a stud point as being a screw for grounding or similar.

Spade terminals may be used like ring terminals but the nice thing about the spade terminal or fork terminals is that the stud does ready to accept connect to it. The spade slide round the stud to get a 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 will find men and women quick disconnect connectors the female will slide on top of 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 may be insulated or non insulated and are avalable in a variety of forms of insulation. The non insulated electrical connector is normally bare copper that has a tin plating. Insulated terminals can come in PVC insulated, nylon insulated as well as heat shrink insulated. The PVC insulated type are usually the cheapest and many common. PVC is often a harder insulation and can crack when crimped and that’s why I do not recommend using them. Amphenol Connector is often a softer insulation and won’t crack once the terminal is crimped. The nylon insulation will likely withstand higher temperatures. I propose using nylon insulated terminals and connectors. Heat shrink insulated terminals and connectors are ideal for applications where the terminal is encountered with outside elements for example high temperatures, rain, snow, and underwater applications.

Heat shrink insulated terminals with adhesive lining create waterproof connections towards the wire. Although heat shrink terminals will not be free those are the best connectors to work with because the last a long and seldom corrode.

When purchasing electrical connectors it is advisable to use UL listed terminals and connectors to make sure you are receiving quality connections. I propose staying away from terminals and connectors which are produced in China because of the poor standards and cheap materials they normally use to make the connectors. Should you search the internet you will find quality terminals and connectors at good prices.
