Adoption of hard engineering plastics, the wire connectors are wear-resistant and practical for use. Plastic shell molding, interior steel, which has better electric conductivity and better grip the wire, won't fall off easily even with strong vibration. Easy to use, simply strip the wire ends and then inserted into the cap, then pressed with pressure pliers. Multi-purpose wire connectors which can be widely applied to electrical products, lighting, household wiring and other wiring equipments.
