The utility model discloses a new -type parallel groove clamp, including being equipped with two left and right sides insulating casing of through wires hole side by side, be equipped with electrically conductive pellet between two through wires holes, the insulating casing bilateral symmetry is equipped with a plurality ofly to the screw via hole, the position that corresponds with the screw viahole on the electrically conductive pellet is equipped with the screw hole, the threaded hole side be equipped with female thread and pointed screw identical. The utility model discloses a new -type parallel groove clamp can shell out the insulating covering of electric wire when using, in direct two through wires holes with two cable inserting insulating casing, held insulating carousel again andpassed screw via hole and electric wire with pointed screw, closed the screw hole of pointed screw and electrically conductive pellet soon each other and fixed. The route is constituteed with pointedscrew and electrically conductive pellet to two electric wires. This new -type parallel groove clamp is fit for being used for connecting band insulating covering's electric wire, and the installation is got up very simple and conveniently, has good insulating properties behind the connecting wire.
