[0029] The present invention provides an electrode connector 100 .

[0030] See also Figures 1 to 7The embodiment of the electrode connector 100 includes a housing 1, a clamping member 2, and a pressing member 3. A socket 111 is provided on the side wall of the housing 1. The clamping member 2 is disposed within the housing 1. The electrode can be inserted into or removed from the clamping member 2 through the socket 111. The pressing member 3 is rotatably connected to the housing 1 and has a first position and a second position. When the pressing member 3 is rotated to the first position, the pressing member 3 applies a tightening force to the clamping member 2 to tighten the electrode and maintain a stable connection between the electrode and the clamping member 2. When the pressing member 3 is rotated to the second position, the tightening force of the pressing member 3 on the clamping member 2 disappears, and the electrode can be removed from the clamping member 2 through the socket 111.

[0031] The electrode connector 100 is used to be installed at the end of the wiring harness 200 of the radio frequency treatment equipment, and is used to stably connect the electrodes of radio frequency treatment and / or electrical stimulation treatment with the wiring harness 200. A clamping part 2 is provided in the electrode connector 100, and the clamping part 2 is used to clamp the inserted electrode, and the material of the clamping part 2 is a metal material to ensure that the clamping part 2 has conductivity and deformation performance. When in use, the wiring harness 200 is passed through the shell 1 and welded to the clamping part 2. A socket 111 is provided on the side wall of the shell 1, and the socket 111 is used to insert the electrode. The inserted electrode can be but is not limited to a sheet-like negative electrode sheet, a sheet-like positive electrode sheet, and a sheet-like radio frequency mask, etc. The electrode is in contact with the clamping part 2 and is conductive, thereby realizing electrical connection between the electrode and the wiring harness 200.

[0032] In the present technical solution, the pressing member 3 is rotatably connected to the housing 1 and has a first position and a second position. In the initial state, the pressing member 3 is in the second position, and the pressing member 3 has no fastening effect on the clamping member 2. The electrode can be freely inserted into the clamping member 2 after being inserted from the socket 111. After the electrode is inserted, the pressing member 3 is rotated to the first position, and the pressing member 3 applies a fastening force to the clamping member 2. The clamping member 2 presses the inserted electrode under the fastening effect of the pressing member 3 and maintains a stable connection between the electrode and the clamping member 2, thereby ensuring that the electrode is not easily detached when the human body moves or the harness 200 is pulled, thereby improving the stability of the connection between the electrode and the connector. When the electrode needs to be taken out, it is only necessary to rotate the pressing member 3 to the second position again to release the fastening effect of the pressing member 3 on the clamping member 2, and the electrode can be detached from the clamping member 2 from the socket 111.

[0033] Through the electrode connector 100, the pressing member 3 can be quickly switched between the first position and the second position by simply turning it slightly, thereby compressing or releasing the pressing member 3, facilitating the insertion or extraction of the electrode, and the operation is convenient and quick.

[0034] In some embodiments of the present invention, the clamping member 2 includes a first clip 21 and a second clip 22 folded in half, with the open and closed ends of the first clip 21 and the second clip 22 facing the socket 111. The electrode is inserted from the socket 111 between the first clip 21 and the second clip 22. At this time, the pressing member 3 is in contact with the first clip 21 or the second clip 22. When the pressing member 3 is rotated to the first position, the pressing member 3 applies a tightening force to the first clip 21 or the second clip 22. When the pressing member 3 is in the second position, the tightening force of the pressing member 3 on the first clip 21 or the second clip 22 disappears.

[0035] In this embodiment, the clamping member 2 includes a first clip 21 and a second clip 22 folded in half, each having a bent end and an open end. The clamping member 2 is disposed within the cavity of the housing 1, with one of the first clip 21 and the second clip 22 being in contact with the bottom wall of the housing 1, while the other can be freely opened and closed, with its open end facing the socket 111. The pressing member 3 is disposed in contact with the first clip 21 or the second clip 22. In the initial state, the pressing member 3 is in the second position, the pressing member 3 has no pressing effect on the clamping member 2, the opening and closing ends of the first clip 21 and the second clip 22 are in a separated state, and the electrode is inserted into the gap between the first clip 21 and the second clip 22 after being inserted from the socket 111. Then the pressing member 3 is rotated to the first position, and the pressing member 3 applies a tightening force to the first clip 21 or the second clip 22, so that the first clip 21 and the second clip 22 are tightly fitted, and the first clip 21 and the second clip 22 then clamp the electrode.

[0036] Among them, the clamping part 2 is a metal spring with elastic deformation ability, so that after the fastening force of the pressing part 3 on the clamping part 2 disappears, the first clamp 21 or the second clamp 22 can automatically pop open the other clamp under the action of its own elastic force, thereby automatically releasing the fastening force of the clamping part 2 on the electrode.

[0037] In the embodiment shown in the figure, the pressing member 3 includes a pressing plate 31 and an eccentric cam 32. The pressing plate 31 is disposed outside the housing 1. The eccentric cam 32 is disposed at one end of the pressing plate 31 and is arranged at an angle to the pressing plate 31. The eccentric cam 32 is rotatably connected to the interior of the housing 1 via a rotating shaft 33. The eccentric cam 32 is disposed in contact with the first clip 21 or the second clip 22. The eccentric cam 32 compresses or releases the first clip 21 and the second clip 22 during rotation.

[0038] Specifically, the housing 1 includes a lower shell 11 and an upper shell 12. The upper shell 12 is detachably covered on the lower shell 11, and the socket 111 is provided on the side wall of the lower shell 11. The upper surface of the upper shell 12 is recessed with a receiving groove 122 for accommodating the pressing plate 31. The shape and size of the receiving groove 122 match the shape and size of the pressing plate 31. The bottom wall of the receiving groove 122 is provided with a avoidance hole 123 for the eccentric cam 32 to pass through. The eccentric cam 32 is inserted into the avoidance hole 123 and is rotatably connected to the lower shell 11 via a rotating shaft 33. When the pressing member 3 is rotated to the first position, the outer surface of the pressing plate 31 is flush with the outer surface of the upper shell 12, thereby ensuring the flatness of the surface of the housing 1. The upper shell 12 is detachably connected to the housing 1, such as a screw connection or a snap connection, so as to facilitate the installation of the clamp 2 and the welding of the wiring harness 200 to the clamp 2.

[0039] Furthermore, the inner wall of the upper shell 12 is provided with a guide rib 121. Figures 4 to 6 As shown, the guide rib 121 is located between the socket 111 and the open and closed ends of the clamping member 2. The first clip 21 is arranged in contact with the bottom plate of the lower shell 11. When the second clip 22 is in a natural state, that is, when the second clip 22 is not pressed by the pressing member 3, the distance between the free end of the second clip 22 and the upper shell 12 is H, and the protruding height of the guide rib 121 is not less than H. The guide rib 121 acts as a barrier to prevent the electrode from tilting upward when inserted through the socket 111, ensuring that the electrode is correctly inserted along the predetermined path between the first clip 21 and the second clip 22, thereby avoiding the problem of incorrect electrode installation due to improper operation.

[0040] In this embodiment, the pressing plate 31 serves as the gripping portion of the pressing member 3. The pressing member 3 can be quickly switched between the first and second positions by simply rotating the pressing plate 31. When the pressing member 3 is in the first position, the eccentric cam 32 applies a tightening force to the first or second clip 21, 22. When the pressing member 3 is in the second position, the tightening force of the eccentric cam 32 on the first or second clip 21, 22 disappears.

[0041] Among them, the cross-sectional size of the eccentric cam 32 gradually decreases from one end facing the pressing plate 31 to the end away from the pressing plate 31. When the pressing member 3 rotates to the first position, the tip of the eccentric cam 32 abuts against the clamping member 2, thereby reducing the contact area between the eccentric cam 32 and the electrode, increasing the pressure between the eccentric cam 32 and the electrode, and then increasing the clamping force of the eccentric cam 32 on the clamping member 2, ensuring a stable connection between the electrode and the clamping member 2.

[0042] Reference Figure 6The rotating shaft 33 of the pressing member 3 is set between the pressing plate 31 and the eccentric cam 32, and the vertical connection line between the rotating shaft 33 and the bottom plate of the shell 1 is defined as the reference line. When the pressing member 3 rotates to the first position, the tip of the eccentric cam 32 deviates from the reference line, and the tip of the eccentric cam 32 is located on the side of the reference line facing the socket 111.

[0043] In this embodiment, the tip of the eccentric cam 32 is positioned on the side of the reference line facing the socket 111. When the eccentric cam 32 rotates from the reference line to the final locking position, the tip of the eccentric cam 32 slides relative to the electrode, thereby gradually increasing the clamping force of the eccentric cam 32 on the electrode, achieving a more stable locking effect. At the same time, it can prevent the pressing member 3 from opening too easily and avoid the problem of unlocking due to accidental contact with the pressing member 3.

[0044] The angle at which the tip of the eccentric cam 32 deviates from the reference line is 5° to 15°, that is, Figure 6 The angle a in the range is between 5° and 15°. If the angle is too large, the eccentric cam 32 clamps the electrode too tightly, making it difficult to open the pressing member 3. If the angle is too small, the eccentric cam 32 does not clamp the electrode enough. The angle at which the tip of the eccentric cam 32 deviates from the reference line is controlled between 5° and 15° to ensure that the clamping and unlocking forces of the pressing member 3 are appropriate.

[0045] When the pressing member 3 is rotated to the first position, the distance between the tip of the eccentric cam 32 and the bottom plate of the housing 1 is defined as L. Figure 6 As shown, the thicknesses of the first clip 21 and the second clip 22 are defined as d1 and d2 respectively, and the thickness of the electrode is d3, d1+d2<L<d1+d2+d3. If L is too large, it cannot be pressed tightly and the electrode is easy to fall out. If L is too small, it is difficult to rotate the pressing piece 3 and the internal stress is too large at this time, which can easily damage the connector. The distance between the tip of the eccentric cam 32 and the bottom plate of the shell 1 is greater than the sum of the thicknesses of the two clips, which can ensure that when the pressing piece 3 is closed, the tip of the eccentric cam 32 can apply sufficient pressure to the first clip 21 and the second clip 22. The distance between the tip of the eccentric cam 32 and the bottom plate of the shell 1 is less than the sum of the thicknesses of the two clips and the thickness of the electrode, which can avoid the problem that the eccentric cam 32 applies too much pressure on the electrode, which makes it difficult to rotate the pressing piece 3 and even causes damage due to excessive stress inside the connector.

[0046] Reference Figure 7 In some embodiments of the present invention, a bulge 23 is provided on the side of the first clip 21 facing the second clip 22 and / or on the side of the second clip 22 facing the first clip 21. When the pressing member 3 is rotated to the first position, the bulge 23 is arranged adjacent to the tip of the eccentric cam 32.

[0047] When the first clamping piece 21 and / or the second clamping piece 22 are clamped with the electrode, the convex bump 23 first contacts the electrode, so that the clamping force on the electrode can be applied on a smaller contact surface, thereby increasing the local pressure and helping to clamp the electrode more firmly.

[0048] Furthermore, a receiving hole 24 is formed on the second clamping piece 22 and / or the first clamping piece 21, which is arranged opposite to the protrusion 23. When the pressing member 3 is rotated to the first position, the protrusion 23 secures the electrode in the receiving hole 24. The electrode is depressed by the protrusion 23 and then sinks into the receiving hole 24, which effectively prevents the electrode from slipping during the clamping process and ensures that the electrode is always kept in the correct position.

[0049] In the embodiment shown in the figure, a first convex hump 23 is provided on the side of the first clip 21 facing the second clip 22, and a second convex hump 23 is provided on the side of the second clip 22 facing the first clip 21. The first convex hump 23 and the second convex hump 23 are spaced apart. A first receiving hole 24 is provided on the second clip 22 and is arranged opposite to the first convex hump 23, and a second receiving hole 24 is provided on the first clip 21 and is arranged opposite to the second convex hump 23. In this way, the direction of the pressing force applied to the electrode by the first convex hump 23 is opposite to the direction of the pressing force applied to the electrode by the second convex hump 23, that is, the electrode is subjected to clamping forces from two directions, which not only provides a more stable clamping effect, but also makes it less likely for the electrode to slide between the two clips, preventing the risk of the electrode slipping during treatment.

[0050] The clamping member 2 is provided with a notch 25 at the bending portion between the first clamping piece 21 and the second clamping piece 22 , which can weaken the mechanical strength of the clamping member 2 at the bending portion and facilitate bending deformation of the clamping member 2 .

[0051] The present electrode connector 100 does not limit the number of clamping members 2; one, two, three, or even more clamping members 2 may be provided. The greater the number of clamping members 2 provided, the stronger the clamping force exerted by the clamping members 2 on the electrode. Preferably, two clamping members 2 are provided, and the two clamping members 2 are arranged side by side within the housing 1. Providing two clamping members 2 can save material while ensuring that the clamping members 2 have sufficient clamping force on the electrode.

[0052] The present invention also provides a radiofrequency treatment device comprising an electrode connector 100 and electrodes for radiofrequency treatment and / or electrical stimulation treatment. The electrode connector 100 is detachably connected to the electrodes. The specific structure of the electrode connector 100 is similar to that of the aforementioned embodiments. Since the present radiofrequency treatment device utilizes all the technical solutions of all of the aforementioned embodiments, it possesses at least all the beneficial effects of the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here.

[0053] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
