Abstract
The utility model relates to a casting copper ground bar and belongs to the field of a connecting device of an electric-conducting circuit; the existing ground bar has the advantages that: the joint is not compact, electric-conducting performance is low, and antiseptic property is low; a layer of copper coating is wholly plated on the surface of the original iron ground bar, the planeness of the end surface of the ground bar is improved, thus leading contact area of two ground bars to be larger when in connection, the combination is more compact, and the electric-conducting performance and the antiseptic property are improved.
Description
Technical field
The utility model belongs to connection device field, conducting wire, and is especially relevant with a kind of cast copper earth rod.
Background technology
Existing be used to conduct electricity the irony earth rod both ends that connect and be provided with screw thread, the butt joint that is used for earth rod is fastening, owing to make the earth rod end face form irregular male and fomale(M﹠F) in earth rod end machining screw, it is not tight to cause two earth rods to engage, therefore under the prerequisite that end thread is not damaged, can use cross grinding or fine cut to make end face smooth, thereby increase the contact-making surface section, increase conductivity, but grinding and meticulous cut cost are than higher, existing production firm often can not adopt, and still there is rough defective in the earth rod end face.
The utility model content
The technical problems to be solved in the utility model will overcome exactly that existing earth rod end face is uneven, and the defective that electric conductivity is not high provides a kind of end face smooth, engages closely, and electric conductivity is superior, the device that Corrosion Protection is good.For this reason, the utility model is by the following technical solutions:
A kind of cast copper earth rod comprises the irony earth rod, it is characterized in that: integral body is coated with the copper coating of one deck on the surface of described irony earth rod.
Use the utility model can reach following beneficial effect: to plate layer of copper by integral body on earth rod, make the smooth of end face change, again because the hardness of copper is less, when connection, end face forms extruding to end face, and it is tightr to make that both ends of the surface engage, and the electric conductivity of copper is better than iron, can greatly improve the conductivity between earth rod and the earth rod,, therefore can improve the decay resistance of earth rod greatly again because the decay resistance of copper is better than iron.
Description of drawings
Fig. 1 is the profile of the utility model front view.
Fig. 2 is the profile of the utility model vertical view.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
As shown in Figure 1 and Figure 2, the utility model is that integral body is coated with the copper coating 2 of one deck on the surface of irony earth rod 1.
When the utility model uses: two cast copper earth rods are screwed in the connector internal thread hole,, after two cast copper earth rods contact, still be rotated again, make cast copper earth rod both ends of the surface mutual extrusion, thereby it is tightr that both ends of the surface are engaged by the connector butt joint.
Claims (1)
1, a kind of cast copper earth rod comprises irony earth rod (1), it is characterized in that: integral body is coated with the copper coating of one deck (2) on the surface of described irony earth rod (1).
