[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting electrode for an air purifier or the like which collects dust by charging dust particles floating in the air.

[0002]

2. Description of the Related Art The configuration of a conventional dust collecting electrode will be described with reference to FIG. In FIG. 3, in the dust collecting electrode wound around the core 17 so that the strip-shaped coated conductive layer 12 and the strip-shaped conductive layer 13 are sequentially superposed at a certain interval, a high-voltage connection terminal 14 and a ground connection are provided. By applying a high DC voltage of several kV between the strip-shaped coated conductive layer 12 and the strip-shaped conductive layer 13 via the terminal 15, the charged dust particles are collected by Coulomb force.

In the above-mentioned dust collecting electrode, a part of the insulating material 21 of the strip-shaped coated conductive layer in order to electrically connect the conductive layer 22 of the coated conductive layer in the strip-shaped coated conductive layer 12 and the high voltage connection terminal 14. 3 was peeled off as shown by the hatched portion of the coating conductive layer 12 as shown in part A of FIG. 3, and was caulked using a metallic rivet 23 to obtain an electrical connection. In the dust collecting electrode, the strip-shaped conductive layer 13 and the ground connection terminal 1 are connected.
Rivet 2 made of metal to electrically connect
The electrical connection was obtained by caulking with No.3.

[0004]

However, a connection terminal must be used for connection to an external terminal as in the case of the dust collecting electrode, and a metallic rivet is used for electrical connection between the conductive layer and the connection terminal. It was caulking using. Also, when using a coated conductive layer, it is necessary to peel off a part of the insulating material to expose the conductive layer, which increases the number of manufacturing steps,
There was a problem that the material cost increased.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to obtain a dust collecting electrode with reduced material costs.

[0006]

In order to achieve the above object, a dust collecting electrode according to the present invention comprises a first conductive layer and a second conductive layer provided at a predetermined interval in a frame of an insulating resin material. The protrusions which are sequentially arranged and provided on the conductive layer disposed outside in the conductive layer are provided as protrusions serving as connection terminals with external terminals, and the protrusions are formed on the frame of the insulating resin material. A notch is provided so as to protrude from the outer surface of the conductive layer. With this configuration, connection with an external terminal can be performed by a protrusion provided on the conductive layer. There is no need for a connection terminal for electrically connecting and a metal rivet for electrically connecting the conductive layer and the connection terminal.
