The magnet 112 is inserted into the magnet accommodating portion 111b of the terminal housing 111 so that the second coupling terminal portion 220 is magnetically coupled to the first coupling terminal portion 110.

The magnet 112 is formed in a donut shape so that the insertion groove 110b can be formed together with the insertion groove through hole 111a in a state of being inserted into the magnet accommodating portion 111b of the terminal housing 111. The insertion groove 110b of the first coupling terminal portion 110 formed by the insertion groove through hole 111a and the magnet 112 can be specifically confirmed from FIG.

On the other hand, the terminal housing 111 is made of a metal through which an electric current can flow.

Next, the conductive pad portion 200 coupled to the low frequency generator 100 by a magnetic force will be described.

The conductive pad portion 200 is rotatably coupled to a connecting seat member 210 provided with a plurality of second coupling terminal portions 220 and a plurality of contact pads for transmitting a low frequency current to the human body. 230 and.

The connecting sheet member 210 of the present embodiment has a heart-shaped sheet shape that covers all of the plurality of first coupling terminal portions 110 provided in the low frequency generator 100.

The connecting seat member 210 is provided with a plurality of second coupling terminal portions 220 that are detachably coupled to the first coupling terminal portion 110 and electrically connected to the first coupling terminal portion 110.

While such a plurality of second coupling terminal portions 220 are coupled to the first coupling terminal portion 110, the connecting seat member 210 is detachably coupled to the lower surface of the low frequency generator 100.

The connecting seat member 210 is formed with a pair of first through holes 211 for rotatably connecting the second coupling terminal portion 220 at positions corresponding to the first coupling terminal portion 110. The first through hole 211 is for penetrating the shaft protrusion 221d of the detachable terminal block 221 described later.

A pair of second coupling terminal portions 220 are rotatably coupled to the connecting seat member 210. Since the second coupling terminal portion 220 is coupled to the first through hole 211 formed at a position corresponding to the first coupling terminal portion 110, it is coupled to the low frequency generator 100 via the second coupling terminal portion 220. The posture of the connecting seat member 210 is fixed with respect to the low frequency generator 100.

A contact pad 230 for transmitting a low frequency current generated from the low frequency generator 100 to the human body is coupled to the lower end portion of the second coupling terminal portion 220, respectively. The plurality of contact pads 230, one side of which is coupled to the second coupling terminal portion 220, are rotatable with respect to the connecting seat member 210 together with the second coupling terminal portion 220. Therefore, the plurality of contact pads 230 can change their postures with respect to the connecting seat member 210 and the low frequency generator 100.

The contact pad 230 receives the transmission of the low frequency current generated from the low frequency generator 100 via the first coupling terminal portion 110 and the second coupling terminal portion 220, and transmits this to the human body.

As can be confirmed from FIG. 7, the second coupling terminal portion 220 of the present embodiment includes the detachable terminal block 221 and the contact pad coupling piece 222, and the first and second washers 223 and 224.

The detachable terminal block 221 is composed of a terminal body 221c and a shaft protrusion 221d, and is made of a metal that can be magnetized and energized.

On the upper side of the terminal body 221c, there are a second magnetic coupling plane 221a that is magnetically coupled to the first magnetic coupling plane 110a of the first coupling terminal portion 110 and is in surface contact with the first magnetic coupling plane 110a, and a second magnetic coupling plane. A columnar insertion protrusion 221b is formed so as to project upward from 221a and be inserted into the insertion groove 110b of the first coupling terminal portion 110.

The shaft protrusion 221d is formed so as to project downward from the lower side of the terminal body 221c, and a locking head 221e is formed at the end of the shaft protrusion 221d (not shown in FIG. 7). The locking head 221e can also be formed by welding or soldering a metal piece, and in the present embodiment, the end portion of the shaft protrusion 221d is crimped to form the head of the rivet. The locking head 221e is formed.

The locking head 221e integrally connects the connecting seat member 210, the first washer 223, and the contact pad coupling piece 222 to the shaft protrusion 221d. In FIG. 7, which shows the separated state of the second coupling terminal portion 220, the locking head 221e cannot be confirmed, and the coupled state of the second coupling terminal portion 220 is shown. At 8, the locking head 221e can be confirmed.

That is, the detachable terminal block 221 is manufactured in the form shown in FIG. 7, and the lower end of the shaft protrusion 221d is fitted with the connecting seat member 210, the first washer 223, and the contact pad coupling piece 222 in that order. By crimping the portions to form the locking head 221e, rivet coupling is performed as shown in FIG.

In addition to the above-mentioned coupling method, the contact pad coupling piece 222 is directly welded to the shaft protrusion 221d with the connecting seat member 210 and the first washer 223 sequentially fitted to the shaft protrusion 221d to perform bonding. It can also be made to be welded. That is, various methods can be presented as a method of connecting the contact pad coupling piece 222 to the shaft protrusion 221d.

The contact pad connecting piece 222 of the present embodiment for joining by the rivet joining method has a third through hole 222b formed and is bent from the edge of the connecting central body 222a extending in the horizontal direction and the connecting central body 222a. Includes a pair of rivets 222c extending downwards.

The third through hole 222b is for penetrating the shaft protrusion 221d of the contact pad coupling piece 222, and the pair of coupling blades 222c is for coupling the contact pad 230 to the contact pad coupling piece 222.

FIG. 7 shows a “∩” -shaped contact pad coupling piece 222 in which a pair of coupling blades 222c is bent downward, and FIG. 8 shows a contact pad 230 and a second washer 224 on the contact pad coupling piece 222. The state in which the end portion of the coupling wing 222c is bent in the horizontal direction is shown so as to be coupled. The specific binding form and method will be described again later.

The first washer 223 has a disk shape, and a second through hole 223a for the shaft protrusion 221d to penetrate is formed in the center thereof. The first washer 223 is interposed between the connecting seat member 210 and the contact pad coupling piece 222 so that the shaft protrusion 221d penetrates the second through hole 223a.

The second washer 224 is joined together when the contact pad 230 is coupled to the contact pad coupling piece 222, and is manufactured in a disk shape like the first washer 223. The second washer 224 is formed with a pair of second slits 224a through which the pair of coupling blades 222c of the contact pad coupling piece 222 penetrates.

On the other hand, the first slit 234, which has not been described in advance, is formed in the contact pad 230, and will be described again with a specific configuration of the contact pad 230.

The contact pads 230 of the present embodiment have a shape in which the width on one side is narrow and the width on the other side is wide, and a pair is provided. Each contact pad 230 has a heart pattern divided in half, and when a pair of contact pads 230 are brought into contact with each other, a heart pattern is formed as shown in FIG. The shape of the contact pad 230 can be variously changed according to the embodiment.

The contact pad 230 includes a pad body 231 made of a flexible and flexible material, a conductive electrode portion 232 provided on the lower surface of the pad body 231 and a conductive adhesive portion 233 provided on the lower surface of the conductive electrode portion 232. Including.

The pad body 231 is made of a flexible material so that it can be bent into a shape corresponding to a contact portion of the human body. As an example, it can be made of rubber, silicone or fabric material.

The conductive electrode portion 232 has a shape that is widely spread so as to correspond to the shape of the pad body 231. The conductive electrode portion 232 contacts the second coupling terminal portion 220 and energizes. The conductive electrode portion 232 is not particularly limited in material and shape as long as it can uniformly transmit a low-frequency current to the human body.

The conductive adhesive portion 233 is provided on the lower surface of the conductive electrode portion 232 and is adhered to the user's skin to transmit the low frequency current transmitted to the conductive electrode portion 232 to the human body.

The conductive adhesive portion 233 of the present embodiment is made of a conductive hydrogel. Conductive hydrogels are hydrophilic polymeric substances and have properties very similar to living tissues. Therefore, when the contact pad 230 is brought into contact with the skin via the conductive adhesive portion 233, the same effect as when the conductive electrode portion 232 is in direct contact with the skin is obtained.

Further, since the conductive adhesive portion 233 made of conductive hydrogel is not completely adhered to the skin, it can be easily attached and detached, and can be used repeatedly as long as it is not contaminated by foreign matter.

Release paper (not shown) adheres to the lower surface of the conductive adhesive portion 233. The release paper is for preventing foreign matter from sticking to the adhesive surface of the conductive adhesive portion 233, and is also used for conventional low-frequency equipment, and is not shown separately.

The contact pad 230 is coupled to the second coupling terminal portion 220 or the connecting seat member 210 so that the contact pad 230 can rotate about the second coupling terminal portion 220 as a rotation center.

A pair of first slits 234 for the pair of coupling blades 222c to penetrate is formed on one side of the contact pad 230. The pair of first slits 234 are formed so as to penetrate the pad body 231 and the conductive electrode portion 232, whereby the coupling blade 222c inserted into the first slit 234 is conducted so as to penetrate the first slit 234. It comes into contact with the sex electrode portion 232.

Next, a specific coupling structure of the connecting seat member 210, the second coupling terminal portion 220, and the contact pad 230 will be described with reference to FIGS. 7 to 9.

The detachable terminal block 221 is located above the connecting seat member 210, and the first washer 223 and the contact pad coupling piece 222 are arranged so as to be sequentially located below the connecting seat member 210.

The shaft protrusion 221d of the detachable terminal block 221 penetrates the first through hole 211 of the connecting seat member 210 and protrudes downward, and the protruding shaft protrusion 221d comes into contact with the second through hole 223a of the first washer 223. The pad coupling piece 222 is sequentially passed through the third through hole 222b.

After that, the end portion of the shaft protrusion 221d is crimped so that the locking head 221e is formed at the end portion of the shaft protrusion 221d. The formed locking head 221e prevents the connecting seat member 210, the first washer 223, and the contact pad coupling piece 222 from detaching from the shaft protrusion 221d of the detachable terminal block 221.

The contact pad 230 is coupled to the contact pad coupling piece 222. The pair of coupling blades 222c penetrates the pair of first slits 234 formed on one side of the contact pad 230 and the second slit 224a formed on the second washer 224 and projects downward so as to project downward. The coupling blade 222c is bent in the horizontal direction so that the contact pad 230 and the second washer 224 are fixed to the contact pad coupling piece 222.

The second washer 224 coupled with the contact pad 230 prevents the first slit 234 of the contact pad 230 from being damaged by the coupling wing 222c and provides an area where the lower surface of the contact pad 230 is supported by the coupling wing 222c. The number is increased so that the contact pad 230 can be stably bonded to the contact pad coupling piece 222.

After the contact pad 230 and the second washer 224 are bonded to the contact pad bonding piece 222, the finishing tape 225 is attached so that the bonded portion is not exposed to the outside.

The plurality of second coupling terminal portions 220 are also separated from the connecting sheet member 210 at regular intervals so that the plurality of first coupling terminal portions 110 are disposed on the lower surface of the low frequency generator 100 at regular intervals. And are placed. Therefore, the contact pad 230 of the conductive pad portion 200 can be easily coupled to the low frequency generator 100 at one time.

In order to separate the conductive pad portion 200 from the low frequency generator 100, all the second coupling terminal portions 220 must be separated from the first coupling terminal portion 110 together, so that the conductive pad portion 200 is low. It can be maintained in a very tightly coupled state with the frequency generator 100.

In particular, even if a force is applied to any of the plurality of contact pads 230, the force is distributed to all the second coupling terminal portions 220 via the connecting seat member 210, so that the specific contact pad to which the force is applied is applied. The 230 is not independently separated from the low frequency generator 100, and the entire conductive pad portion 200 is maintained in a tightly coupled state with the low frequency generator 100.

The first coupling terminal portion 110 and the second coupling terminal portion 220 of the variable low-frequency device according to the present embodiment are magnetically coupled by a magnet 112 inserted into the first coupling terminal portion 110.

Since the second coupling terminal portion 220 is made of a magnetizable metal, when it is brought close to the first coupling terminal portion 110, magnetic coupling is performed by a magnet 112 provided inside the first coupling terminal portion 110.

The first coupling terminal portion 110 has a structure including a first magnetic coupling plane 110a and a circular insertion groove 110b, and the second coupling terminal portion 220 is a second magnetic coupling plane that is magnetically coupled to the first magnetic coupling plane 110a. The structure includes a 221a and a cylindrical insertion protrusion 221b to be inserted into the insertion groove 110b.

Therefore, the insertion projection 221b is inserted into the insertion groove 110b and can be easily coupled to the fixed position only by bringing the second coupling terminal portion 220 close to the first coupling terminal portion 110.

The insertion protrusion 221b inserted into the insertion groove 110b prevents the first and second magnetic coupling planes 110a and 221a from slipping each other in a state where the second coupling terminal portion 220 is coupled to the first coupling terminal portion 110. To prevent the combined position from shifting.

That is, while the contact pad 230 is attached to the body and used, the conductive pad portion 200 is not easily separated from the low frequency generator 100 even if the wearer moves violently.

The contact pad 230 is rotatable with respect to the connecting seat member 210 together with the second coupling terminal portion 220. Further, the second coupling terminal portion 220 is rotatably coupled to the first coupling terminal portion 110 of the low frequency generator 100. Therefore, the contact pad 230 can be rotated together with the second coupling terminal portion 220 to easily change the posture with respect to the low frequency generator 100.

Even if the first coupling terminal portion 110 and the second coupling terminal portion 220 that are magnetically coupled rotate in contact with each other, the coupling force due to the magnetic force does not decrease, so that they are not easily separated.

Further, since the connecting seat member 210 maintains a posture fixed to the low frequency generator 100 by the plurality of second coupling terminal portions 220, the second coupling seat member 210 is second while the contact pad 230 is rotated to change the posture. The coupling terminal portion 220 is not easily separated from the first coupling terminal portion 110.

On the other hand, the two contact pads 230 must not interfere with each other as they must come into contact with the skin in a state of being separated from each other. As described above, the contact pad 230 of the present embodiment has a shape in which one side has a narrower width than the other side, so that even if the two contact pads 230 are rotated to some extent, they do not interfere with each other.

By rotating the contact pad 230 to deform the form of the variable low-frequency device according to the present embodiment, the two contact pads 230 can be easily attached to a portion where the body breaks or protrudes, such as a joint. ..

In particular, it can be easily used on parts such as the neck, shoulders, wrists, and elbows where it is difficult to attach conventional low-frequency devices to which the contact pads are fixed in a straight line, so the usable range is wider than before. Enlarge greatly.

Therefore, it is used for general purposes such as stimulating tendons and ligaments in joints that are difficult to stimulate with conventional low-frequency devices to relieve pain, or to strengthen specific muscles. Is possible.

In this embodiment, a mode in which a pair of contact pads 230 are provided is illustrated, but this is only an example. Depending on the embodiment, it may be implemented in a form in which two or more pairs of contact pads 230 are provided.

Even when two or more pairs of contact pads 230 are provided, all the contact pads 230 must be rotatably coupled to the connecting seat member 210 via the second coupling terminal 220.

The above description of the present invention is for illustration purposes only, and a person having ordinary knowledge in the technical field to which the present invention belongs does not change the technical idea or essential features of the present invention. You can see that it can be easily transformed in various forms.

Therefore, it should be understood that the embodiments described above are merely exemplary in all respects and are not limiting. For example, each component described in a single type may be implemented in a distributed manner, and components described as similarly distributed may also be implemented in a combined form.

The scope of the present invention is indicated by the scope of claims, which will be described later, rather than the above detailed description, and the meaning and scope of the scope of claims, and all modifications or modifications derived from the concept of equality thereof, of the present invention It should be interpreted as being included in the scope.
