Are formed so as to project, and the pins are formed so as to be fitted into the receiving holes 21 formed in the conductive layer 20. The reference numeral 30 in FIG. 1 indicates a plug for connecting the base ends of the respective cords together to the main body 10.

Reference numeral 16 shown in FIG. 1 denotes an electrode connecting member as a connecting means in the present invention. As shown in FIG. 3, two columnar members 16A are integrally formed and each columnar member is formed. A pair of through holes 32 through which the cord 14 penetrates are formed at the center of the member.

As shown in FIG. 3, the through hole 32 is formed with a long diameter hole 32A having a diameter larger than the diameter of the cord from the substantially center in the longitudinal direction of the cylindrical body to the end portion on the electrode 12 side, while the other A short diameter hole 32B slightly shorter than the diameter of the cord is formed on the end side.

The connector 16 has a hole 32 through which a cord passes.
Since it has A and 32B, it can be slid along the cord, and the connector can slide with the cord in the short-diameter hole 32B, so that it can be connected at a desired position on the cord 14 when not sliding. The tool can be fixed.

By sliding the connector 16 to the electrode side, the base end portion 28B (see FIG. 2) of the boss portion has the long hole 32 of the connector.
The pair of electrodes 12 are maintained close to each other when they are almost fitted into A, and the electrodes are connected. On the other hand, when the connection of the electrodes is released, the connecting tool 16 may be slid in the opposite direction.

As described above, according to the present embodiment, since the pair of electrodes can be attached to the body in advance by the connecting tool 16 in a state of being in close proximity to each other, the electrodes are prevented from being separated from each other and are displaced from each other so that there is stiffness. The electrode can be effectively concentrated and applied to the affected pot. If it is desired to widely apply the electrode to the body, the connecting tool may be slid toward the main body to release the connection of the electrode. When connecting the electrodes,
It is desirable to connect via a slight gap to prevent a short circuit between the electrodes.

FIGS. 4 and 5 show a second embodiment of the electrode connecting structure. The difference from the above-mentioned embodiment is that the connecting tool 16 is detachable. Connector 1
The conductor cord 6 is divided into two parts with one end of the conductor cord in the perpendicular direction opened, and each of the divided members 16C and 16D is configured so that the open end side 41 rotates around the fixed end 40. Engagement protrusions 42 and engagement holes 44 are formed on the facing surfaces on the open end side of the respective divided bodies, and when the respective divided bodies are made to face each other and pressed, they are engaged with each other and the coupling tool 16 and the electrodes are mutually attached. It can be fixed in a position where it can be connected. However, the connector of this embodiment can be fixed on the conductor cord 14 as in the first embodiment and then slid on the cord 14.

FIG. 6 shows a third embodiment of the electrode connecting structure, in which a pair of engaging holes 36 are formed in the triangular sheet electrodes 12 at positions adjacent to each other so as to correspond to a connecting tool. , The engaging piece 16E having the pair of engaging protrusions 38 is used to form the engaging protrusions 38 into the engaging holes 3 as shown by the alternate long and short dash line.
6, a pair of electrodes can be connected to each other by engaging with 6. In this embodiment, since the sheet electrode is formed in a triangular shape, the boss portion 2
8 is formed so as not to be at the end portion of the sheet electrode but at substantially the center position. The shape of the electrode according to the present invention may be circular, as well as triangular as in the present embodiment.

FIGS. 7 to 10 show a fourth embodiment of the electrode connecting structure, in which the connecting means is integrally formed with the sheet electrode. Specifically, a flange 45 (corresponding to a convex portion of the present invention) is formed around the boss portion 28 protruding outside the electrode, and this flange has a trapezoidal groove in the protruding portion 70 (the present invention). Equivalent to a recess) 50
As shown in FIG. 10, the electrodes can be connected to each other by being fitted inside.

The flange 45 and the projecting portion 70 are integrally formed with the base body 18 of the electrode in a trapezoidal shape such that the cord 14 side is a short side on the surface of the electrode. As shown in FIG. The flat concave portion 50 into which the flange 45 is inserted is formed over the entire length of the protruding portion 70, and the surface thereof is partially open. A protrusion 74 is formed downward from the center of the lower surface of the flange portion 45 of FIG. 8, and a small hole 78 is formed from the opening surface of the recess 50 toward the inside of the sheet electrode (see FIG. 7). .

In this embodiment, a pair of electrodes can be connected to each other as shown in FIG. 10 simply by fitting the flange 45 protruding outside one electrode into the flat recess 50 of the other electrode. Moreover, since the projections 74 and the small holes 78 of both electrodes are engaged with each other, the connection of both electrodes becomes more stable. In order to prevent a short circuit between both electrodes, it is desirable to provide the protrusion 74 and the small hole 78 at a position where both electrodes can be connected to each other through a slight gap.

According to this embodiment, since the connecting means is integrally formed with the electrode instead of the separate member, the connecting tool can be stored,
Alternatively, problems such as loss can be solved. Furthermore, since the surface of the protrusion 70 is open,
The conductor cord 14 of the electrode can be delivered outside the electrode without being interrupted.

11 to 13 show a fifth embodiment of the electrode connecting structure. This embodiment is different from each of the above-mentioned embodiments in that the pair of electrodes 12 are attached to the second sheet electrode 58 as the conductor of the present invention to be connected to each other.

A second base body 60 made of rubber, a second conductive layer 62 made of conductive silicone rubber integrally molded with the second base body 60, and a second conductive layer 62 attached to the body surface. The second adhesive pad 64 is detachably attachable.

On the surface of the second substrate 60, a pair of openings 66 having substantially the same size as the first sheet electrode 12 are formed so as not to be continuous with each other. The conductive surface 62A on the surface of the conductive layer 62 is exposed. Therefore, the first pair of sheet electrodes 12 can be connected to each other by attaching the first sheet electrodes 12 to the conductive surfaces 62A exposed from the openings 66, respectively. A pair of the second conductive layers 62 is provided corresponding to each sheet electrode 12, and the pair of second conductive layers 62 are shielded from each other by the base body 60 made of silicon rubber which functions as an insulator. Therefore, even if the first sheet electrode 12 is attached to the second sheet electrode 61, it is possible to prevent short-circuiting with each other.

According to this embodiment, the first sheet electrode 12
By connecting the first adhesive pad 22 of the second sheet electrode 58 to the conductive surface 62A of the second sheet electrode 58, both electrodes are electrically connected, and the low-frequency current generated from the first adhesive pad 22 and the like. Can be transmitted to the body through the second conductive layer 62 and the second adhesive pad 64.

The conductive layer 62 of the second sheet electrode 58 according to the present embodiment has an area substantially similar to the area of the first conductive layer on the connection side with the first electrode, but is connected to the body. On the side, the area is larger than this. Therefore, the electrode area of the conductive surface 62B on the body side is enlarged, and the probability of applying the electrode to the pot of the body can be increased.

In the embodiment of FIG. 14, a pair of second sheet electrodes 58A separated from each other is detachably attached to the first sheet electrode 12. This second sheet electrode has substantially the same structure as that of the second sheet electrode shown in FIGS.

According to this embodiment, since the second sheet electrode can be detachably attached to the first sheet electrode, the electrode area can be increased only when desired. Moreover, since the size of the electrode is increased, it is possible to increase the probability of hitting the electrode with the vase.

In the present invention, the means for connecting the electrodes is not limited to the one described in the above embodiment, and any means capable of connecting the electrodes may be used.
