Description
Technical field
The present invention relates to a kind of distribution box, in particular to a kind of low-tension distribution box of line apparatus with ground.
Background technique
Currently, in order to guarantee the safety of service personnel, it is first right to need before maintenance when overhauling to low-tension distribution box
Route inside low-tension distribution box is grounded.Currently used grounding wire device generally includes to be grounded, the both ends of ground line
It is respectively arranged with electrical wire clip, when carrying out ground connection operation, the wiring in one of electrical wire clip and low-tension distribution box will be grounded
Column is connected, another electrical wire clip is connected with ground path.But in the actual operation process, due to adjacent in low-tension distribution box
The distance between two binding posts are smaller, and traditional electrical wire clip volume is larger, therefore electrical wire clip is often because of insufficient space
And be difficult to attach on binding post, bigger difficulty is caused to ground connection operation.
For example China Patent Publication No. CN102456957A, a kind of entitled earthing wire clip, insulation support arm are solid
Determine that inverted U insulation support arm is installed on pedestal, probe aluminium strip is installed outside insulation support arm, inside insulation support arm
