[0004]

However, in the above-mentioned prior art, since the connecting portion between the electrode supporting portion and the cover is not sealed, the device is installed in a place with high humidity, a place where water is easily sprayed, and the like. In an atmosphere, water easily penetrates into the electrode support, lowering the insulation of the terminals in the electrode support,
There is a danger of short circuit or short circuit. An object of the present invention is to provide an electrode support capable of improving the sealing property in the electrode support.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to an electrode which is detachably mounted on a fixing member installed in a housing or the like of a facility and is drawn out from the facility. An electrode support having a built-in terminal to which a rod and a wire for supplying power from the outside are connected, and an opening in the electrode support;
And a cover that covers the opening.
With the power supply wire connected to the terminal of the electrode support , the cover is mounted on the opening of the electrode support,

Further, a coupler for connecting an end of a pipe into which the power supply wire is inserted is formed on a side wall of the electrode support so as to protrude from a lead-out portion of the power supply wire in the electrode support. Can be kept.

[0006]

According to the above-described means, in a state where the wire cut in advance to a predetermined length is connected to the terminal of the electrode support, welding or bonding is performed so that no gap exists between the electrode support and the cover. The electrode support and the cover are integrated in a mold state. Therefore, it is possible to prevent water or the like from intruding into the electrode support from the outside, and to prevent an accident such as a short circuit from occurring. In the case where the electrode support portion and the cover portion are both made of a resin material, the heat applied to the bonding surface (opposing surface) by the heating means welds the bonding surface and seals the bonding surface. Stop and integration are performed. In the case of resin materials and other materials, sealing and integration of the bonding surfaces are performed by adhesion. In particular, originally

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an assembled perspective view showing one embodiment of the electrode support according to the present invention. 2 and 3
FIG. 4 is an explanatory diagram showing an installation order. FIG. 4 is a front view showing a working example of the electrode support according to the present invention. FIG.
As shown in the figure, an electrode support 8 according to the present invention connects a plurality of wires 9 (vinyl-coated wires or the like) cut in advance to a predetermined length (for example, several meters) in a factory or the like to a terminal portion in the electrode support. Thereafter, the bonding surface between the electrode support and the cover shown in FIG. 5 is welded by a heating means or bonded with a resin adhesive or the like to achieve a structure in which integration and sealing are achieved. FIG. 1 shows a state after the electrode support and the cover are integrated.

In this case, the electrode support and the cover have substantially the same structure as shown in FIG. 5, but the shape of the lead-out portion of the wire 9 is greatly different from the conventional structure. That is, after the installation of the electrode support is completed, the wire 9 is inserted into the pipe (shown in FIG. 4). In order to connect the end of the pipe to the electrode support 8, a threadless pipe connection coupler 10 is used. Are projected from the side surface of the electrode support. Conventionally, the electrode support part 2, the cover 3, and the wire 5 were separately brought to a construction site (installation site) as separate components and assembled in a specified order. On the other hand, according to the present invention, these are integrally assembled in advance and further brought into a construction site after being made into a sealing structure (for this reason, the wire 9 is cut in advance to a necessary minimum length). ), The connection of the wire rods and the work of attaching the cover only need to be performed by attaching the electrode support 8.

Conventionally, a wire-drawing portion is provided with a slit-shaped outlet as shown in FIG. 6 so that the wire can be easily inserted and positioned because the wire needs to be attached on site. Due to the structure, the sealability was poor, and water and the like easily entered. On the other hand, in the present invention, the wire 9
The pipe connecting coupler 10 has a pipe shape so that the pipe can be inserted, and the pipe is fitted to the pipe connecting coupler 10 outside, so that an extremely high sealing structure can be obtained. In addition, a rubber packing or the like for waterproofing can be attached to the pipe connection coupler 10 as needed. As mentioned above,
Since the electrode support portion and the cover are integrated and a structure is employed in which no gap is formed between the wire 9 and the electrode support 8, it is possible to prevent water or the like from entering the electrode support 8. . Incidentally, in the conventional configuration, it is inevitable that a gap is formed between the periphery of the wire and the electrode support portion 2, and it is impossible to prevent water or the like from entering the terminal portion.

However, according to the structure shown in FIG. 1, it is possible to prevent water or the like from entering the electrode holder 8, to reduce the number of electrical accidents, and to improve the reliability. In addition, since it is not necessary to attach the cover and to connect the wires, it is possible to reduce the work time on site and the number of man-hours. Furthermore, it is possible to eliminate the loss of parts and forgetting to bring them in. Next, an installation procedure of the electrode support according to the present invention will be described with reference to FIGS. 1 to 3 and FIG.

First, one end of a wire 9 cut to a predetermined length (for example, 3 meters) is drawn into the electrode support 8 through a pipe connection coupler 10, and the tip thereof is connected to a predetermined terminal portion of the electrode support 8. Connect to position. At this time, the other end (power supply side) of the wire 9 is marked one by one (addition of a number or the like) so that which wire is connected to which terminal can be identified at the time of installation. Next, as described above, if the electrode support and the cover are integrated by welding or bonding so as to eliminate the gap, the electrode support 8 is completed.

As described above, the electrode support 8 to which the wire 9 is connected in advance and the casing is sealed is brought to the site and installation work is performed. First, as shown in FIG. 4, a fixing member 1 is attached to a coupling 7 vertically mounted in advance on the upper surface of a facility (spring tank or the like) as shown in FIG.
Screw it in and fix it. Further, as shown in FIG. 3, after each of the electrode rods 6 is screwed into a predetermined position in the electrode support 8,
The electrode rod 6 is fixed with a screw or the like to prevent the electrode rod 6 from dropping off naturally. The number of electrode rods 6 is large (for example, 5
In this case, in order to facilitate the fixing operation, the operation is started from the electrode rod to be mounted at the center, and the outer electrode rod is put on the back.

Next, after positioning the electrode holder 8 on the fixed member 1 with the electrode rod 6 inserted into the fixed member 1, the electrode holder 8 is brought into close contact with the fixed member 1, and in this state, an arrow A When the electrode support 8 is rotated in the direction, the bayonet-type joint is fastened. After the electrode supporter 8 and the fixing member 1 are connected in this manner, the screws 11 are screwed into screw holes provided at predetermined positions on the upper surface of the electrode supporter 8, and the electrode supporter 8 rotates on the fixing member 1. Fix so that there is no. Further, the wire 9 is passed through the pipe 12, and an end of the pipe 12 is connected to the pipe connection coupler 10. On the other hand, piping 1
The other end of 2 and the other end of the wire 9 are guided to a joint box 13 attached to a wall surface, and are mechanically and electrically connected. An external power line is connected to the joint box 13.

As described above, in the electrode support according to the embodiment of the present invention, since the main body and the cover of the electrode support are integrated into a mold, the penetration of water or the like is prevented. There are no openings or gaps, and a high waterproof effect can be obtained. In the above embodiment, the pipe connection coupler 10 is of a screwless type, but may be of a threaded type. In addition, a plurality of wirings are identified by numbers or the like, but the color of the covering (the outermost vinyl coating or the like) may be different for each wiring. Or,
The tags may be linked one by one. further,
In the above embodiment, an example in which the present invention is applied to equipment that handles water or the like has been described. However, the present invention is not limited to water, and the present invention can be applied to a case where the present invention is used in equipment that handles liquid other than water.
In the above embodiment, the fixing member 1 and the electrode support 8 are connected by the bayonet type, but may be screwed.

[0015]

As is clear from the above, according to the present invention, since the electrode support portion and the cover portion are integrated before installation at the site, water and the like do not enter the electrode support device. Therefore, a high waterproof effect can be obtained, and the reliability can be improved. Further, the work time required for installation can be reduced.
