Difficulty: EasyWire Preparation Tools

An electronics technician needs to attach a solderless ring terminal to the end of a stranded copper conductor. Which specialized wire preparation tool is designed to compress and permanently deform the terminal barrel onto the wire?

  1. A
    Diagonal cutters
  2. Wire crimperAnswer
  3. C
    Wire stripper
  4. D
    Cable ripper

Answer

Wire crimper
A wire crimper features contoured jaw nests specifically designed to exert uniform compressive force on a solderless connector barrel, creating a reliable mechanical and electrical joint without severing the conductor strands.

Step-by-Step Solution

1
Identify the primary mechanical operation required by the task.
The task requires compressing and deforming a solderless terminal barrel around exposed conductor strands.
Solderless terminals require controlled mechanical deformation to form a gas-tight, low-resistance electrical and mechanical bond.
2
Select the appropriate electrical hand tool designed for this specific mechanical function.
The wire crimper (crimping tool) is the dedicated hand tool engineered with matching jaw cavities for terminal installation.
Other tools like strippers, cutters, and rippers perform material removal or severing rather than controlled compression.
