Description

Lightning Ground Plate Fasteners {Fastener for Lightning Plate}

The present invention relates to a lightning strike plate fastener that is installed in the underground buried portion of the telegraph pole can easily and effectively perform the grounding of lightning.

Lightning rods are installed in the telephone poles, and copper wires connected to the lightning rods are buried underground to earth the lightning. Conventionally, as shown in Figure 6, four ground copper piles (21) all around the telephone pole 20, and connected to the connection wire 22 as a fence. Such a grounding structure is cumbersome for installation work, the price of the ground copper 21 is expensive and the installation area is wide, the amount of work increases. The ground copper 21 should be kept at a distance of 30 cm from the telephone pole because the electric current of the lightning strikes the wet telephone pole and damages the transformer and the like.

The present invention aims to provide lightning arrester ground plate fasteners that can be easily installed and reduce the workload of grounding structures.

In order to achieve this purpose, the present invention focuses on a structure that is fastened around the telephone pole and prevents electric shock and easy fastening structure. In addition, the grounding effect is excellent and the cost of raw materials is reduced.

The present invention will be described in detail with reference to the accompanying drawings.

The present invention is basically composed of two members are combined, one to two auxiliary members can be added separately to match the diameter of the telephone pole. The first member 1 and the second member 2 are fastened to each other to form a unitary body and finally installed around the telephone pole with the fastening belt 17, and the ground copper plate 18 is seated around the first member 1 and the second member 2.

As shown in FIG. 1, the basic configuration of the present invention includes a recess 9 and an inserting portion 11 and an inserting portion 13 formed at one side thereof, and arranged at equal intervals on the front side thereof, and a locking step 5 at the top thereof. ) And a first member 1 having a spacer 4 having a seat groove 6 formed thereon, and corresponding to the insertion piece 11 and the insertion portion 13 of the first member 1 on one side thereof. Insertion portion 13 and the insertion piece 11 of the lower opposite position is formed and the other side is formed with a coupling projection 10 corresponding to the recess groove 9 and the front side is disposed at equal intervals and the locking jaw (5) at the top And a second member 2 having a spacer 4 formed with a seat groove 6.

The spacer 4 adjacent to the other end of the first member 1 and the second member 2 is formed with a recess 7 and a belt hole 8. A key piece 12 is inserted into the back of the insertion piece 11. The insertion part 14 and the key groove 15 are formed in the attachment part 13.

The combined state of the first member 1 and the second member 2 is shown in FIGS. 2 and 3. In addition, the same structure or short connecting member 16 is illustrated in FIG. As for the connecting member 16, normally, two kinds of one and two spacers 4 are selectively used according to the diameter of a telephone pole.

The first member 1 and the second member 2 are fitted to each other by the female and male inserting portions 13 and the inserting pieces 11. The insertion piece 11 enters the insertion hole 14 of the insertion portion 13, and the key piece 12 on the rear surface of the insertion piece 11 is securely fastened by being caught by the key groove 15 of the insertion portion 13. The first member 1 and the second member 2 fastened in this way are wound around the telephone pole 20, and then the coupling protrusion 10 is inserted into the recess groove 9 and a separate tightening belt 17 is recessed ( 7) and the belt hole 8 is firmly installed in the telephone pole 20. As such, when the first member 1 and the second member 2 or the connecting member 16 are fastened to the telegraph pole 20, the ground copper plate 18 is wound around the seat groove 6 of the spacer 4. The ground copper wire 19 is connected to the ground copper plate 18.

Since the ground copper plate 18 of the present invention has a large area, the grounding effect is sufficiently exhibited, and the risk of electric leakage is effectively blocked by the insulating plate 3 and the spacer 4 made of plastic.

The present invention saves 25% in the cost of the whole equipment by replacing the expensive ground copper file with the ground copper plate, and the installation range is reduced, making the installation work extremely easy.
