Abstract
The invention discloses a clamp for fixing an optical fiber reinforcing member. The clamp comprises an upper clamp and a lower clamp which are rectangular respectively. The central part of one long side of the upper clamp is provided with a first U-shaped opening. Two sides of the first U-shaped opening are provided with chutes. First V-shaped troughs are arranged between the chutes and the U-shaped opening. The central part of one long side of the lower clamp is provided with a second U-shaped opening of which the size is same with that of the first U-shaped opening, and furthermore the central part of the second U-shaped opening is provided with a fixed shaft core. Two sides of the U-shaped opening are provided with threaded holes. Second V-shaped troughs which match the first V-shaped troughs are arranged between the threaded holes and the second U-shaped opening. The upper clamp is fixed with the lower clamp through screws. The clamp has functions of ensuring high fixing firmness of the reinforcing member, ensuring safe construction tension of an optical cable in a construction process and long-time safe operation of the optical cable, realizing convenient and quick operation, and obtaining remarkable fixing effect.
