Problems solved by technology

[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 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, easy to loosen, short service life, frequent maintenance; small contact surface, requires professional tools, inconvenient installation, poor versatility

Embodiment 1

[0020] Such as figure 1 and figure 2 As shown, a multi-directional rotating connection cable clamp is characterized in that it includes two movably connected cable clamps, each cable clamp includes a clamp body 1, and a groove 2 is provided in the clamp body 1, and the concave A moving chuck 3 that can move up and down is embedded in the groove 2. A static chuck 4 opposite to the clamping end of the moving chuck 3 is fixedly connected to the clamp body 1. The opening orientation of the clamp body 1 and the groove 2 is opposite. One side is provided with a bolt hole, and an adjusting bolt 5 passes through the bolt hole and is fixedly connected with the clamp body 1 , and is connected with the movable chuck 3 at the same time. The sizes of the two cable clamps can be the same or different, and can hold cables with the same or different thicknesses. The two movable cable clamps are back-to-back structure, face-to-face structure or back-to-face structure. The back-to-back struc...

Embodiment 2

[0022] On the basis of embodiment 1, this embodiment has been improved as follows:

[0023] One side or both sides of the movable chuck 3 of one of the two movably connected cable clamps is provided with downward check sawtooth, and the outer side of the check sawtooth of the movable clamp 3 is provided with The anti-loosening anti-reversal sawtooth sheet 6 matched with it, at least one side of the anti-loosening anti-reversal sawtooth sheet 6 and the clamp body is provided with a compression spring 7, the movable chuck 3 and the anti-loosening anti-reversal sawtooth sheet 6 Compressed by clip spring 7. Wherein the compression spring 7 is a wave-shaped leaf spring or a columnar spring, and the columnar spring can be a cylindrical helical spring, preferably a leaf spring. The difference from Example 1 when disassembling is that the outer protective cover 8 needs to be disassembled first, the compression spring 7 is taken out, the anti-loosening anti-reverse saw-tooth piece 6 i...

Embodiment 3

[0025] On the basis of embodiment 1, this embodiment has been improved as follows:

[0026] One side or both sides of the movable clamp 3 of each cable clamp of the two movably connected cable clamps are respectively provided with downward check sawtooth, and the outer side of the check sawtooth of the movable clamp 3 is provided with There is an anti-loosening anti-reversal sawtooth sheet 6 matched with it, and a compression spring 7 is arranged between the anti-loosening and anti-reversal sawtooth sheet 6 on at least one side and the clamp body, and the movable chuck 3 and the anti-loosening and anti-reversal sawtooth sheet 6 is compressed by stage clip 7. Wherein the compression spring 7 is a wave-shaped leaf spring or a columnar spring, and the columnar spring can be a cylindrical helical spring, preferably a leaf spring. The difference from Example 1 when disassembling is that the outer protective cover 8 needs to be disassembled first, the compression spring 7 is taken ...

Abstract

The invention discloses a multidirectional rotary connection cable clamp. The clamp is characterized by comprising two movably connected cable clamps, wherein each cable clamp comprises a clamp body, a groove is arranged in the clamp body, a movable chuck capable of moving up and down is embedded into the groove, a fixed chuck opposite to the clamping end of the movable chuck is fixedly connected to the clamp body, a bolt hole is arranged on one side of the clamp body opposite to the opening direction of the groove, and an adjusting bolt penetrates through the bolt hole, is fixedly connected with the clamp body and abuts against the movable chuck. The clamp is high in generality, capable of being suitable for various diameters of cables, simple in structure, reasonable in design, balanced in pressure, constant in clamping force, small in contact resistance, reliable in connection and safe in use.

Description

technical field [0001] The invention relates to a cable clamp, in particular to a multi-directional rotating connection 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, has a short service life and frequent maintenance; the contact surface is small, professional tools are required, installation is inconvenient, and the versatility is poor. Contents of the invention [0003...
