Good material: These uninsulated end-to-end connectors are made of durable tinned copper, rust-resistant and corrosion, for durable use with good electrical conductivity. Simple design: The non-insulated crimping connector is rolling and has no insulation, and there is a wire stop at the center for a clear appearance. They are housed in a storage box to avoid easy losses and storage. Good performance: Our wire-to-end connectors are crimped and can be easily resolved after crimping. The threads can be connected without damaging the terminals. Application: Widely used to connect or build custom cable bundles in machines, power supply, railways, shipbuilding, aviation, home appliances, computers or other automatic equipment.
