Abstract
The utility model provides an unthreaded connector for a copper-plating steel bar grounding electrode, which comprises two sections of copper-plating steel bars and a connector, wherein the connector is of an unthreaded connector (2), and the unthreaded connector (2) is of an unthreaded sleeve which is in interference fit with the two sections of copper-plating steel bars (1,3); the inner diameter of the unthreaded connector (2) is in a butted-tapered shape, i.e. the inner diameter D1of the two ends of the unthreaded connector (2) is larger than the inner diameter D2 of the middle thereof; and D1-D2 = 0.3mm + /-0.25mm, and the diameter D of the copper-plating steel bars (1,3) is equal to the inner diameter D1 of the two ends of the unthreaded connector (2). The utility model eliminates the inner threads of an ordinary connector and the copper-plating steel bars, so that the connection is more convenient, the operation is simple, the production process is simple, the production cost is lowered, and the use is safe and reliable.
Description
Technical field
The utility model relates to a kind of copper facing rod iron earth electrode does not have screw thread coupling, is used for the usefulness of the prolongation connection of copper facing rod iron earth electrode.
Background technology
The connector mechanical connection is the main connected mode of copper facing rod iron earth electrode, and it connects the overall performance quality that tightness degree has determined copper facing rod iron earth electrode.Screw thread coupling is arranged because simple in structure, easy to connect, safe and reliable, at home and abroad obtained in the connection of copper facing rod iron earth electrode using widely, yet copper facing rod iron earth electrode in transit, can't be connected with screw thread coupling is arranged because of a silk mouthful modification takes place in collision easily, the copper plated steel bastinade is when underground, driving force is by conducting between copper facing rod iron and the copper facing rod iron, can't exempt damage, cause simple question complicated for the reliability of connector connector and copper facing rod iron screw thread.At present, some place takes the chamotte fusing mode to connect copper facing rod iron earth electrode both at home and abroad, and the reliability of its connection is higher than screw thread coupling, and still, because its cost is high slightly, the construction procedure relative complex can not get promoting on a large scale always.
Summary of the invention
The utility model is at above situation, and developing a kind of removal has the copper facing rod iron earth electrode of screw thread coupling internal thread not have screw thread coupling.
The technical solution of the utility model: copper facing rod iron earth electrode of the present utility model does not have screw thread coupling and comprises two sections copper facing rod irons and connector, its connector is no screw thread coupling, no screw thread coupling is the no threaded sleeve with two sections copper facing rod iron interference fit, the internal diameter of no screw thread coupling is taper, promptly there be not the inside diameter D 2 of the inside diameter D 1 at screw thread coupling two ends greater than its centre, D1-D2=0.3mm+/-0.25mm.
Described copper facing rod iron earth electrode does not have screw thread coupling, and the diameter D of its copper facing rod iron equals not have the inside diameter D 1 at screw thread coupling two ends.
Advantage of the present utility model: the utility model has been removed the internal thread of common connector and copper facing rod iron, make connection more convenient, simple to operate, production process is simple, reduce production costs, safe and reliable, avoided the problem that has screw thread copper facing rod iron in transportation, can't be connected with connector because of silk mouth modification, this no screw thread coupling has also been simplified the production process of copper facing rod iron earth electrode, and copper facing rod iron earth electrode two ends can not make screw thread, the copper plated steel bastinade is when underground, guarantee that strength is by the conduction between copper facing rod iron and the copper facing rod iron, exempted the possibility that connector damages, ensured the reliability that connects.

Embodiment
As Fig. 1, Fig. 2, Fig. 3: among the figure: copper facing rod iron 1,3, no screw thread coupling 2. copper facing rod iron earth electrodes of the present utility model do not have screw thread coupling and comprise two sections copper facing rod irons and connector, connector is no screw thread coupling 2, no screw thread coupling 2 is the no threaded sleeves with two sections copper facing rod irons, 1,3 interference fit, the internal diameter of no screw thread coupling 2 is taper, the inside diameter D 1 of promptly not having screw thread coupling 2 two ends is greater than the inside diameter D 2 in the middle of it, D1-D2=0.3mm+/-0.25mm. copper facing rod iron 1 and 3 diameter D equal not have the inside diameter D 1. at screw thread coupling 2 two ends
Using method:
(1) will there be the end that screw thread coupling 2 is fixed in copper facing rod iron 1;
(2) copper facing rod iron 1 is knocked in no screw thread coupling 2, built-in length is 1/3 of no screw thread coupling length;
(3) other end built-in length of an end of another root copper facing rod iron 3 being knocked in no screw thread coupling 2 is 1/3 of no screw thread coupling length;
Two copper facing rod irons that (4) will couple together 1,3 continue to beat in no screw thread coupling 2, and two copper facing rod irons 1 are got final product with 3 tight contact of end face.
Claims (2)
1. a copper facing rod iron earth electrode does not have screw thread coupling, comprise two sections copper facing rod irons and connector, it is characterized in that: connector is a no screw thread coupling (2), no screw thread coupling (2) is the no threaded sleeve with two sections copper facing rod irons (1,3) interference fit, the internal diameter of no screw thread coupling (2) is taper, promptly there be not the inside diameter D 2 of the inside diameter D 1 at screw thread coupling (2) two ends greater than its centre, D1-D2=0.3mm+/-0.25mm.
2. copper facing rod iron earth electrode according to claim 1 does not have screw thread coupling, it is characterized in that: the inside diameter D 1 at the diameter D of copper facing rod iron (1,3) equals not have screw thread coupling (2) two ends.
