What is the main difference between crimping tools for insulated terminals and those for non-insulated terminals?

The primary distinction between crimping tools for insulated terminals and those for non-insulated terminals lies in the design and structure of the crimping jaws. Non-insulated crimpers typically feature sharper teeth or edges that are specifically designed to secure the metal terminal onto a wire without the additional shielding of insulation. This design allows for a more precise grip and a secure connection, which is crucial when dealing with bare wires that need a solid electrical connection.

In contrast, insulated crimpers are crafted to work with terminals that have a protective insulation covering, focusing instead on the placement and compression of the terminal rather than the cutting action that is emphasized in non-insulated crimpers. The difference in design reflects the specific requirements of crimping insulated versus non-insulated terminals, making the sharper teeth on non-insulated crimpers an essential characteristic for their intended use.

The other choices, while mentioning aspects that might be relevant to the context of crimping, do not accurately capture the fundamental difference between the crimping tools designed for insulated and non-insulated terminals. This focus on the mechanical attributes directly correlates to their applications in electrical work, underscoring the importance of selecting the appropriate tool for the specific type of terminal being used.
