DOWNLEAD CONNECTING CLAMP Russian patent published in 2025 - IPC H01R4/00 B23B31/20 

FIELD: electricity.

SUBSTANCE: invention relates to devices and clamps intended for connection of electrical conductors during installation of electric installations or construction of cable and overhead power lines, in particular during installation of earthing devices. Downlead clamp for connection of electric conductors comprises a housing with holes made in it, which are intended for placement of electric conductors and clamping elements ensuring crimping of conductors in the hole of the housing. At that, the housing sections around each hole are made conical in the form of collets with separate blades made integral with the housing, and the clamping elements are made in the form of a nut with an inner conical surface, which is screwed on the threaded section of the housing with the possibility of contacting by its inner conical surface with the outer conical surface of the blades of the collets, which crimp the conductor. According to the invention, between the blades of each collet there is a locking member fixed to the housing which restricts the rotation of the broken-off blades of the collet about the opening with the conductor inside.

EFFECT: higher reliability of wires connection.
