Grounding cable clamp

Abstract

The invention discloses a grounding cable clamp comprising a cable clamp body provided with a groove. A movable clamp head capable of moving vertically is embedded into the groove. The cable clamp body is provided with a grounding connection device. A fixed clamp head opposite to the movable clamp head is fixedly connected above the cable clamp body, a bolt hole is arranged below the cable clamp body, and an adjustable bolt penetrates through the bolt hole to be fixedly connected with the cable clamp body while connectedly butts against the movable clamp head. Nonreturn sawteeth which is nonreturn down is arranged on one or two sides of the movable clamp head. Anti-loosing nonreturn sawteeth pieces are matched with the nonreturn sawteeth and arranged at outside of the nonreturn sawteeth of the movable clamp head. A pressure spring is arranged between the anti-loosing nonreturn sawteeth piece and the cable clamp body at at least one side. The movable clamp head and the anti-loosing nonreturn sawteeth pieces are pressed tightly by the pressure spring. The grounding cable clamp is high in universality, simple in structure, balanced in pressure, constant in clamping force, small in contact resistance, stable and reliable in connection, convenient for mounting of a grounding wire, convenient to use and safe to mount, and even can trigger lightning discharge so as to protect the cables.

Description

technical field [0001] The invention relates to a cable clamp, in particular to a grounding cable clamp. Background technique [0002] In today's society, it is very important to use electricity safely and ensure the safe and stable operation of the power grid. The poor handling of wire connections has brought a lot of trouble to people, and even has potential safety hazards. The existing clamps are unevenly loaded on one side and easily deformed on one side. When the nut is tightened, it will slide to the left and right sides. It requires multiple adjustments to align, which increases the difficulty of operation; it cannot be self-locking, and the connection is not stable. Affected by thermal expansion and contraction, it is easy to loosen, the service life is short, and maintenance is frequent; the contact surface is small, professional tools are required, installation is inconvenient, and the versatility is poor.

[0002] In today's society, it is very important to use electricity safely and ensure the safe and stable operation of the power grid. The poor connection of wires has brought a lot of trouble to people, and even has potential safety hazards.

The existing clamps are unevenly stressed on one side and easily deformed on one side. When the nut is tightened, it will slide to the left and right sides. It takes multiple adjustments to align, which increases the difficulty of operation; it cannot be self-locking, and the connection is not stable. Affected by thermal expansion and contraction, it is easy to loosen, the service life is short, and maintenance is frequent; the contact surface is small, professional tools are required, installation is inconvenient, and the versatility is poor. It is inconvenient to install the grounding wire when repairing the cable, and it cannot cause lightning discharge. Thunderstorm cable Vulnerable
