A specialized electrical connector designed to establish an electrical connection through the insulation of one or more conductors without requiring the removal of that insulation. These connectors typically utilize sharp, metallic teeth or blades that pierce the insulation layer, creating a secure and reliable electrical pathway to the conductor core. A common example involves tapping into an existing cable to power a new device without cutting or stripping the original wire.
This method offers several advantages, including reduced installation time, minimized risk of conductor damage, and improved connection reliability due to the prevention of moisture and contaminants from entering the connection point. Historically, these connectors were developed to streamline electrical installations and maintenance, particularly in applications where disrupting existing circuits was undesirable or impractical. Their use contributes to overall system integrity and efficiency.
