What are splice connectors?

A splice connector is a special type of connector designed to crimp two or more wires together by cutting through their plastic insulating jackets. This type of connector consists of a sharp metal insert that enables the connector to safely cut through the insulation and establish a quick and secure connection. By doing so, the power from a source cable can be easily transferred to the next cable. 

Types

Splice connectors are available in different varieties. Two of the most common types are:

• Crimp butt splice terminal: These types of splice connectors have a tube shape with two crimps. Crimp butt splice terminals are generally used to change, lengthen and/or repair conductors.
• Crimp closed end terminal: These types of splice connectors are designed to terminate wires and secure them from being exposed to oxygen and moisture, thus preventing corrosion.

Other than these, splice connectors are also available as push wire terminals and crimp barrel foil terminals. 

How do splice connectors work?

A splice connector works by cutting through the insulation and crimping wires together. There is a plastic clip in the splice connector that has a sharp metal insert. This metal insert cuts through the insulating jackets with precision and crimps together two or more wires. The splice connector plastic clip thus secures the wires together without needing any soldering.
