Thomas and Betts
Dragon Tooth? Insulation Piercing Crimp Connectors

Magnet wire (copper or aluminum) is a very common type of wire that is used in home appliances, the automotive industry (anti-lock braking systems, power windows, etc.), furnaces, lawn tools, and the electrical motor and transformer industries. It is Ideal for Winding Coils, Inductors, Transformers, Lighting, Ballasts, Relays & Timers, and Motor Applications.

Magnet wire is available with many types of insulation, depending on the end use. For example Polyurethane, which is suitable for use up to 130C, has good solderability. Other film types such as Polyesterimide (180C), and Armored Polyesterimide (220C) are very tough, and due to their high temperature stability are not suitable for soldering except with removal of the jacket. Therefore, due to the toughness and high temperature stability of the insulation, it creates problems splicing and terminating.

Another problem is when manufacturers need to connect aluminum magnet wire to copper. The two materials exhibit different thermal properties, as well as different responses to various temperatures seen in the applications.

Thomas and Betts (T&B) has a unique solution to these issues with their Dragon Tooth® Insulation piercing terminals. Now you no longer need to weld or remove the outer jacket of the magnet wire to perform your splices or terminations.

 Features

  • Made of tin plated copper for high conductivity and excellent corrosion resistance.
  • Insulation piercing “teeth”
  • For use in aluminum and copper magnet wire connections
  • Available with bolt holes, fork terminals, or as splices or disconnects
  • Accommodates wire sizes #20 to #4/0 AWG and cmil from 50K to 230K
  • When compressed onto insulated magnet wire, the teeth penetrate the jacket and bite into the conductor, providing extra strength, and less sliding action.
  • Will penetrate all standard copper and aluminum magnet wire insulations such as: heavy Formvar, poly-thermaleze polyester, polyurethane, etc.
