Abstract
The utility model discloses a ground bar which comprises an insulating rod and a screw ejector rod that is arranged at the end part of the insulating rod; the screw ejector rod is provided with a frame-shaped rod with a side opening and passes through the bottom edge of the frame-shaped rod; the top edge of the frame-shaped rod is provided with two connecting rods that form an included angle of 60 degrees; and the direction of the included angle faces the insulating rod. The head of the ground bar is not slotted so that the strength of the head of the ground bar is reinforced and the connecting resistance of the ground bar is reduced; the screw ejection pressure acted on grounding wires in the frame is acted at the bottom and side edges of the frame-shaped rod so that the contacting area and the compactness of the ground bar head and a wire can be increased effectively and the contacting resistance can be reduced; the material can be saved by simple design; and the machining technology is also very simple and practical and is convenient for generalization.
Description
Technical field
The utility model relates to a kind of power construction earthing device, is specifically related to a kind of earth rod.
Background technology
At present, the earth rod top of using at a line has two square grooves, be connected and fixed end and two movable aluminium pressing plates with two joint establishment annealed copper wires in the square groove, the connected mode of annealed copper wire and aluminium pressing plate has reduced the intensity of ground connection caput, is easy to generate phenomenons such as loose contact in construction; In addition, when earth lead is treated in the crimping of movable aluminium pressing plate, rely on spring crimping lead, crimping is not firm, and reliability is not strong, and the resistance that connects is big; At last, the processing technology complexity of this earth rod.
The utility model content
The problems referred to above, a kind of intensity of design that the purpose of this utility model is to solve prior art is big, reliable operation, technology is simple, contact is good earth rod.
A kind of earth rod comprises insulating bar and the spiral push rod that the insulating bar end is set, and lateral opening shaped as frame bar is set on the described spiral push rod, and the spiral push rod passes the base of described shaped as frame bar.
The end that described spiral push rod passes described shaped as frame bar is provided with the top pad.
The side of described shaped as frame bar is provided with rotary screw.
The top margin of described shaped as frame bar is that two angles are 60 ° of bar connecting rods, and the direction of angle is towards insulating bar.
The beneficial effects of the utility model are: the utility model ground connection caput is not slotted, and has strengthened the intensity of ground connection caput, has reduced connection resistance; The spiral roof pressure of earth connection in the bottom of described shaped as frame bar and side are provided with frame has increased the contact area and the tightness of ground connection caput and lead effectively, has reduced contact resistance; Material has been saved in simple design, and processing technology is also very simple, and practicality is convenient to promote.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1: a kind of earth rod, comprise insulating bar 1 and the spiral push rod 2 that insulating bar 1 end is set, lateral opening shaped as frame bar 3 is set on the described spiral push rod 2, spiral push rod 2 passes the base of described shaped as frame bar 3.
The end that described spiral push rod 2 passes described shaped as frame bar 3 is provided with top pad 5.
The side of described shaped as frame bar 3 is provided with rotary screw 4.
The top margin of described shaped as frame bar is that two angles are 60 ° of bar connecting rods, and the direction of angle is towards insulating bar.
The beneficial effects of the utility model are: the utility model ground connection caput is not slotted, and has strengthened the intensity of ground connection caput, has reduced contact resistance; The spiral roof pressure of earth connection in the bottom of described shaped as frame bar and side arrange frame has increased contact area and the tight ness rating of ground connection caput and lead effectively, has reduced contact resistance; Material has been saved in simple design, and processing technology is also very simple, and practicality is convenient to promote.
Claims (3)
