Abstract
The utility model discloses a low-voltage ground clamp used for a compact electrical structure. A first fixture body is disposed on an upper part of a support and one end is clamped between two sheets of the support. A second fixture body is disposed on an end of an arc-shaped or zigzag connecting rod. The other end of the arc-shaped or zigzag connecting rod is hinged between the two sheets of the support. A hinged end of the arc-shaped or zigzag connecting rod is provided with a return spring. On a lower part of the support, a flat nut is disposed below the arc-shaped or zigzag connecting rod. An adjustable bolt is jointed in the flat nut in a screwed manner. A lower part of the adjustable bolt is provided with a connecting device which can be connected with an insulating operation rod.

The second described clamp body arc or zigzag connecting rod be set to it is compressed and is hinged on connecting rod by holddown spring.
Junction at the second clamp body and connecting rod arranges holddown spring, can improve the thrust of this clamp body.
The second described clamp body is plates structure, and position is provided with two to the lug of downward-extension in the middle, is provided with connecting hole on lug, and connecting rod is stuck in the middle of two lugs, and one end of the second clamp body is supported on connecting rod.
On the clamping face of the first clamp body, be provided with dentalation.
On the clamping face of the first clamp body, dentalation is set, the frictional force in the time of can improving clamping.
Two of described support is the structure of 7 fonts, and the horizontal edge position of 7 fonts is used for fixing the first clamp body, and the two ends of the first clamp body are locked on horizontal edge.
Adopt the support of this structure, can play the effect of supporting the first clamp body, thereby improve the clamping force of clamping.
7 font hypotenuses of support adopt two threaded connectors to lock, and two threaded connectors are respectively in 7 lower left corners of font hypotenuse and the medium position on the right.
Adopt the connected mode of this location arrangements, can guarantee the adjusting of adjusting bolt angle, can guarantee again the firm grip of support.
The jockey that adjusting bolt bottom is connected with insulated operating rod is for to be symmetrically arranged with bearing pin in the bottom of insulated operating rod.
In sum, the utility model following advantage compared to existing technology:
Compact electrical structure low-voltage ground wire clamp of the present utility model, between the first clamp body and the second clamp body, the way of contact is designed to rotate pinching, guarantees that earthing clamp and quilt are connect conductor contact reliable.Simultaneously because the angle of adjusting bolt is adjustable, thereby realize wire clamp jaws direction adjustable function, to can aim at easily connect busbar.
