Top: wire terminating in an insulated ferrule Center: Several ferrules with colored insulation, and two uninsulated ferrules Insulated, and uninsulated ferrules. An electric wire ferrule (sometimes electric end terminal) is a metal tube crimped over stranded wire to secure the strands within a screw terminal.
Crimp tool for 0.14 mm 2 to 10 mm 2 (26–8 AWG) insulated and non-insulated ferrules. Crimping is a method of joining two or more pieces of metal or other ductile material by deforming one or both of them to hold the other. The bend or deformity is called the crimp. [1] [2] Crimping tools are used to create crimps.
A simple spring clamp, used on an automotive vacuum hose. Another type of spring clamp, typically only used on vacuum hoses, is just a piece of spring steel wire bent into a loop, with the ends curled to provide handles. These are used similar to standard spring clamps, but are just pinched by hand, and provide very little clamping force.
F-Crimp is a more mechanically robust crimp connection compared to the common barrel-crimp type readily available at retail locations (Radio Shack, Home Depot, etc.). It also has an optional second crimp section that crimps to the insulation, providing strain relief. Because of these characteristics, automobiles use F-Crimp almost exclusively.
For power circuits, the color-coding uses the same colors as residential construction, and adds the additional wires used for three-phase systems. Black, Red and Blue are used for hot wires and White is used as the neutral wire in a 120/208 V circuit. Brown, Orange and Yellow are used as hot wires and gray is used as the neutral wire in a 277/ ...
