A so-called silent discharge type large-capacity ozone generator for generating ozone is used.

A large number of discharge tubes as shown in FIG. 3 are used in this silent discharge type ozone generator. In FIG. 3, 1
Is a discharge tube composed of a glass tube (dielectric tube) whose one end is closed, and a high voltage electrode 2 is formed on the inner circumference of the discharge tube by coating a metal such as Al or SUS.
A metal brush 3 and a fuse 4 that come into contact with the high-voltage electrode 2 are arranged on the inner circumference of the discharge tube 1, and a male screw portion 5 is engraved at the tip of the fuse 4.

In the discharge tube constructed as shown in FIG. 3, its high voltage electrode must be connected to a high voltage insulator (not shown). In this case, as shown in FIG. 4, the external thread 5 of the discharge tube 1
At, the metal plate 6 is attached with screws 7 to connect the discharge tubes 1 to each other. Further, the discharge tube 1 and a high-voltage insulator (not shown)

A large-capacity ozone generator uses tens to hundreds of tens of discharge tubes. In order for all the discharge tubes to be electrically connected, at least two or more metal plates 6 must be projected from one discharge tube, and the number of metal plates must be equal to or more than the number of discharge tubes. And
Connection work was difficult. In addition, it becomes uncertain whether or not all the discharge tubes are electrically connected, as the number of discharge tubes increases, and there is a high possibility that some discharge tubes are not connected.

The present invention has been made in view of the above points, and an object thereof is a discharge tube connecting device and a discharge tube connecting method for an ozone generator capable of surely connecting a large number of discharge tubes by a simple connecting operation. To provide.

BEST MODE FOR CARRYING OUT THE INVENTION The discharge tube connecting device of the present invention is constructed as shown in FIG. FIG. 1 shows only the portion inserted into the discharge tube 11. In FIG. 1, one end of a metal plate 16 is preliminarily fixed by welding to the tip portion of a fuse 14 inserted into the inner peripheral portion of the discharge tube. Further, inside the welded portion of the metal plate 16 and inside the tip of the fuse 14, the female screw 1
7 is engraved. An elongated hole 18 is provided at the other end of the metal plate 16. The distance between the female screw 17 and the elongated hole 18 is formed to be equal to the distance between the centers of adjacent discharge tubes.

A plurality of discharge tubes 11b to 11n are arranged so that a plurality of concentric circles are formed around the center of 1a and are adjacent to the elongated hole 18 of the metal plate 16 of the discharge tube on the same circle. The female screw 17 of the discharge tube is screwed and connected. Next, the other end of the fuse of the discharge tube 11a serving as the center,
The metal plates 6 similar to the conventional one are connected to the high voltage insulators 21 provided on the outer peripheral portions of the plurality of discharge tubes so as to bridge all concentric circles. The discharge tube 1 which is the center of this
The method of connecting 1a and all the concentric circles and the high-voltage insulator 21 is not limited to the metal plate 6 but may be a conductive wire or the like.

With such a connecting method, a large number of discharge tubes can be easily connected. Since one end of the metal plate 16 is fixed to the fuse 14 in advance, the discharge tube can be surely connected by a simple work of screwing the long hole and the female screw.
