The invention discloses a wire clamp, belonging to the technical field of clamps. The wire clamp comprises a wire clamp body and a fixing clamp. The fixing clamp is arranged below the wire clamp body; the upper end surface of the wire clamp body is longitudinally provided with a plurality of wire slots; and wire penetrating holes are downwards disposed in front of the wire slots. The production efficiency is improved. A plurality of wires are fixed on the wire clamp, and then the wires are fixed on a PCB printed circuit board together, thus the wires are only stressed in the vertical direction and can not be stressed independently, and the wires are well fixed.
