However, since this connection is a metal-to-metal contact, it is prone to slipping, and it may come loose due to impact when driving the grounding rod, resulting in poor contact between the grounding rod and the electric wire, or the connection may come off. This has been a problem in terms of security and performance maintenance.

を圧着させている。 FIG. 1 shows a state in which an electric wire 2 is connected to the upper end of the grounding rod 1 by a clamping ring 3. The grounding rod 1 is made of steel, copper, or a steel rod coated with copper, and the electric wire 2 and the clamping ring 3 are made of copper or a copper alloy. It is. Asperities 10 are formed on the outer peripheral surface of the grounding rod 1.
The unevenness 10 can be formed, for example, by scattered recesses as shown in FIG. 2, or by grooves extending in the circumferential direction as shown in FIG. 3. With the grounding rod 1 and the electric wire 2 passed through the clamping ring 3, the grounding rod 1 is deformed by an appropriate clamping tool at the location where the unevenness 10 is formed, and the grounding rod 1 and the electric wire 2 are respectively compressed. At the same time, the grounding rod 1 and the electric wire 2 are crimped.

が得られる。 Therefore, clamping can be easily achieved with an ordinary clamping tool, and in this clamping state, the inner surface of the clamping ring 3 and the electric wire 2 are deformed along the unevenness 10 of the grounding rod 1, and are in a biting state. The clamping ring 3 and the ground rod 1 and the electric wire 2 and the ground rod 1 are firmly and firmly connected, and as a result, a reliable and strong connection between the ground rod and the electric wire is obtained.
凹凸１０への圧締リング３の前記喰込み状態
は、圧締リング３を接地棒１より変形容易な、或
いはほぼ同等の変形容易性を有した材料のものと
することにより、より確実に得られる。 The above-mentioned biting state of the clamping ring 3 into the unevenness 10 can be more reliably achieved by making the clamping ring 3 of a material that is more easily deformable than the ground rod 1 or has approximately the same deformability. It will be done.
溝により凹凸１０を形成する場合、該溝を接地

れるような凹凸とするのが望ましい。 When the unevenness 10 is formed by a groove, the groove can be made to extend in the longitudinal direction of the grounding rod 1, but in order to make the connection more reliable and strong, it should be made to extend in the circumferential direction as shown in Fig. 3. , or extending in a direction oblique to the longitudinal direction, etc.
It is desirable that the grounding rod be uneven so that peaks or valleys appear in the cross section along the longitudinal direction.
