Insulated Ring Terminals Fixable _ good elasticity _ to bear collosion _ unable broken

(1) Non-insulated terminals are simple tin-plated copper connectors. These are the least expensive because they have no insulation and are one piece only. They are used when there will never be any danger of someone short circuiting the connection through inadvertent touching.

(2) PVC insulated terminals are the most common. The barrel of the terminal is insulated with PVC plastic to protect against short circuits. The PVC and the copper barrel are crimped once to fix the terminal to the bare wire.

(3) Nylon insulated terminals are sometimes called “double crimp” terminals. They are crimped once on the bare wire and once on the insulation of the wire. This makes the “pull-out strength” of the terminal much superior. This product is ideal for high vibration or heavy industrial applications since the crimp is extra secure. Note that nylon insulation has a distinct clear look to it.

(4) Heat shrink insulated terminals utilize a plastic and glue that insulates the connection. After crimping or soldering the terminal, a torch or electric heat gun is used to shrink the insulation around the wire and the glue inside the insulation makes a moisture resistant seal. This product is ideal for trucks, autos, and other applications where dust and moisture could compromise the connection.
