As a preferred solution, the nuts of the bolt connection pair are butterfly nuts.

As a preferred solution, the grounding rod is provided with a depth warning mark, so as to facilitate judging whether the depth of the grounding pile into the ground meets the safety regulations.

As a preferred solution, the connection terminal has a wire hole to connect with an external cable.

As a preferred solution, the wire hole is crimped with the external cable.

As a preferred solution, the distance between the two through holes on the ground rod for fixing the position of the copper terminal is between 20-25 mm.

As a preferred solution, the distance between the handle of the grounding stake and the nearest of the two through holes of the grounding stake is 100-200mm.

As a preferred solution, the ground rod has recessed areas at the positions of the two through holes to accommodate the connecting terminals.

As a preferred solution, the size of the recessed area along the axial direction of the ground rod is between 200-400 mm.

Compared with the prior art, the electric grounding pile of the utility model has the following beneficial effects:

The utility model adopts two-hole copper terminals and two bolt connection pairs to connect the grounding pile and the grounding wire, so that the connection is not easy to loose during use, can ensure good grounding of the equipment, meet the needs of ground discharge, and improve the grounding pile. The safety of construction personnel is guaranteed. In addition, butterfly nuts are used instead of ordinary nuts for the bolt connection pair, and the grounding pile has a handle, which makes installation and disassembly convenient, reduces construction difficulty, and saves manpower and time.

【Detailed ways】

Below in conjunction with accompanying drawing, the utility model is described in detail below.

As shown in the accompanying drawing 1, the electric grounding pile provided by one embodiment of the utility model includes a grounding pile body 1, a copper terminal 2 and a bolt connection pair 3, and the grounding pile body 1 includes a grounding pile handle 11 and a grounding rod 12 , the ground stake handle 11 is fixedly connected to the ground rod 12, and the ground rod is provided with two through holes 13 for fixing the position of the copper terminal 2. In FIG. 1 , diagrams (a) and (b) mainly show the front and side of the grounding pile body 1 , and diagram (c) shows the grounding pile body 1 installed with copper terminals 2 and cables.

The ground rod 12 is mainly used for inserting into the ground, so as to realize the ground connection. The ground stake handle 11 is mainly used to facilitate the user to ground the ground rod 12 or pull it up. In this embodiment, the top end of the grounding rod 12 is connected to the middle part of the grounding stake handle 11 , that is, forms a T shape. It should be appreciated that, as an alternative, the top end of the ground rod 12 may be connected to one end of the ground stake handle 11, ie, form an L shape.

Preferably, the distance a between the two through holes 13 on the ground rod 12 for fixing the position of the copper terminal is between 20-25mm (millimeter). The distance b between the handle of the ground stake and the nearest of the two through holes of the ground stake is 100-200mm.

Preferably, the ground rod has a recessed area (see figure a and figure b) at the position of the two through holes to accommodate the connection terminal. The size of the recessed area along the axial direction of the ground rod is between 200-400mm.

As shown in Figure 2, the bolt connection pair 3 includes bolts, butterfly nuts and gaskets, the bolt connection pair 3 is used to fix the copper terminal 2 on the ground pile body 1, and the copper terminal 2 is Two-hole copper connection terminal, the two holes of the copper connection terminal 2 are aligned with the two through holes 13 on the ground rod 12 for bolts to pass through. The nuts of the bolt connection pair 3 are butterfly nuts, and each nut has two arms protruding from the outside, which is convenient for users to tighten and loosen by hand.

In this embodiment, when the grounding pile is in use, first arrange the wire ends of the grounding wire and stuff them into the wire hole 21 of the two-hole copper terminal 2; After crimping, ensure that the wire end is electrically connected to the copper terminal 2. Fix the crimped ground wire on the ground rod 12 with a butterfly nut, and ensure that the bolts are tightened.
