Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrode, and particularly to a rod-shaped anode electrode used in a humidifier or an ionized water generator.

For example, in an ionized water generator, a pair of electrodes is attached to the bottom of a container containing liquid, that is, an electrolytic cell, or a pair of electrodes is fixed to the top lid of the container, and the top lid is placed over the container, so that the electrodes can be connected to the liquid inside the container. It is designed to affect the liquid and give it an ionizing effect.

In the case of the latter type, in which the electrode is attached to the top lid of the container, if a rod-shaped sintered alloy or the like is used for the anode electrode, a hole is made in the upper end of the electrode 1, as shown in Figure 1, and this hole is A threaded rod 3 is embedded in the upper cover with a conductive resin 2 interposed therebetween, and this threaded rod is fixed to the upper cover with a nut.

FIG. 2 shows the state in which the anode electrode 1 is attached to the upper lid 4. The screw rod 3 of the electrode 1 configured as described above is inserted into the hole 4a of the upper lid 4, and the The crimp terminal 7 of the lead wire is tightened with a nut 8 through washers 5 and 6.

Reference numeral 9 denotes a rubber gasket installed between the electrode main body 1a and the upper lid 4 to prevent water leakage.

The conductive resin 2 is for making good electrical contact between the electrode body 1a and the threaded rod 3.

The threaded rod 3 is simply fixed to the electrode body 1a by the conductive resin 2.

In such a conventional electrode, when the nut 8 is tightened to firmly fix the crimp terminal 7, a force as shown by the arrow in FIG. 2 acts between the electrode body and the threaded rod 3, and the screw There is a drawback that the threaded rod 3 may come off from the electrode body 1a if tensile force is applied to the rod 3 and the conductive resin 2.

The object of the present invention is to provide an electrode free of such drawbacks.

Hereinafter, the present invention will be described with reference to FIGS. 3 and 4.
An example will be explained.

FIG. 3 is a vertical sectional view showing the upper part of the electrode 1 according to the embodiment of the present invention.

A resin mold 11 having a U-shaped vertical cross section is fixed to the offshore belly 3a of the threaded rod 3 by insert molding.
After that, insert the lower part 3b of the threaded rod 3 into a hole previously formed in the upper end of the electrode body 1a made of ferrite, for example.
It is embedded and fixed with a conductive resin 2 interposed therebetween.

The gap between the electrode body 1a and the resin mold 11 is filled with a sealing resin 10 as shown in the figure, and then the measurement is performed.

This filling sealing resin 10 prevents water in the container (not shown) from entering between the threaded rod 3 and the conductive resin 2, and also prevents the electrode body 1a, the resin mold 11. This is to make the fixing between the screw rods 3 more effective.

The electrode 1 of the present invention having such a structure is attached to the container top cover 4 or a suitable electrode holding plate as shown in FIG.

The manner of this installation is almost the same as that explained with reference to FIG.
The washers 5 and 6 and the crimp terminal 7 of the lead wire 12 are placed on the upper surface of the upper cover 4 and tightened with a nut 8.

At this time, since the threaded rod 3 and the resin mold 11 are integrally fixed by insert molding, the tensile force of the threaded rod 3 due to the tightening of the nut 8 is due to the compression between the upper surface of the resin mold 11 and the lower surface of the packing 9. A force acts between both surfaces, and the force is applied downward from the resin mold 11, that is, the lower part 3 of the threaded rod 3.
It has no effect on b.

Therefore, no force due to the tightening of the nut as described in connection with FIG. 2 acts between the conductive resin 2 or the resin mold 11 and the electrode body 1a, and the threaded rod 3 is pulled out from the electrode body 1a. There isn't.

The present invention is useful not only for electrodes attached to the top cover of ionized water generators, but also for similar electrodes built into electrode-type humidifiers and other home appliances.
