絕緣穿刺線夾(Insulation Piercing Connectors)主要由絕緣殼體、穿刺刀片、防水膠墊、力矩螺栓組成。當做電纜分支連接時，將分支電纜插入支線帽并確定好主線分支位置后，用套筒扳手擰緊線夾上的力矩螺母，隨著力矩螺母的擰緊，線夾上下兩塊暗藏有穿刺刀片的絕緣體逐漸合攏，同時，包裹在穿刺刀片周圍的弧形密封膠墊逐步緊貼電纜絕緣層，穿刺刀片亦開始穿刺電纜絕緣層及金屬導體。當密封膠墊和絕緣油脂的密封程度和穿刺刀片與金屬體的接觸達到效果時，力矩螺母自動脫落，此時，安裝完成且接觸點密封和電氣效果達到。
  
The Insulation Piercing Connectors is mainly composed of an insulating shell, a piercing blade, a waterproof rubber pad and a torque bolt. As a branch of cable connection, the branch cable is inserted into the cap and confirm the main branch line position, the torque nut with the socket wrench, tighten the clamp with tightening torque nut, clamp down two pieces of a puncture blade insulator gradually closed, at the same time, wrapped in a curved blade gradually around the puncture sealing pad close to the cable insulation layer, the puncture blade also began to layer and a metal conductor insulation puncture cable. When the sealing degree of the sealant pad and the insulation grease reaches the best effect when the contact between the puncture blade and the metal body reaches the best effect, the torque nut automatically falls off. At this time, the installation is completed, and the contact point seal and the electric effect reach the best.
