[0028] Most common electrode connectors on the market connect cables and radiofrequency therapy devices using either threaded or pull-out connectors. Threaded connectors are cumbersome to assemble and disassemble, while pull-out connectors, while convenient, can damage the connection due to frequent plugging and unplugging, increasing wear and tear costs.

[0029] The utility model provides an electrode connector and a radio frequency treatment device, aiming to realize convenient disassembly of electrodes and reduce consumable material costs.

[0030] See also Figures 1 to 4 In one embodiment of the present invention, the electrode connector is used to connect an electrode 5 for radio frequency and / or electrical stimulation therapy. The electrode connector includes a housing 1, a circuit board 2, a pressing member 3, and a pressing member 4. A relief opening 11 is provided on the top of the housing 1, and an insertion opening 12 for inserting or removing the electrode 5 from the housing 1 is provided on the side wall of the housing 1; a plurality of conductive elastic pins 21 are provided on the surface of the circuit board 2 facing the relief opening 11, and the circuit board 2 is disposed in the housing 1; one end of the pressing member 4 abuts against the pressing member 3, and the pressing member 3 covers the plurality of conductive elastic pins 21; wherein, one end of the pressing member 4 is accommodated in the relief opening 11, and can be rotatably connected to the housing 1 relative to the housing 1, and has a first position and a second position;

[0031] When the pressing member 4 is in the first position, one end of the pressing member 4 applies a certain tightening force to the pressing member 3 to tighten the electrode 5 and maintain a stable electrical connection between the electrode 5 and the multiple conductive spring pins 21 of the circuit board 2;

[0032] When the pressing member 4 is located at the second position, the fastening force applied by one end of the pressing member 4 disappears, and the electrode 5 can be detached from the insertion port 12 .

[0033] In this embodiment, the shell 1 is made of hard plastic material, which is strong, durable and insulated, and can protect the internal circuit board 2, electrode 5 or cable, etc., and can prevent conductive short circuits. The shape of the shell 1 is not limited here and can be determined according to actual conditions. The circuit board 2 can be a PCBA or other types of circuit boards 2. The circuit board 2 is arranged inside the shell 1 and can play a role in protecting the circuit board 2. A plurality of conductive elastic pins 21 are provided on one surface of the circuit board 2 facing the avoidance opening 11. Through the plurality of conductive elastic pins 21, the connection of electrodes 5 at different pin positions can be achieved. There is a spring inside the conductive elastic pin to achieve adaptive fitting of different electrode 5 contours within the travel range, while achieving electrical conduction and transmission of control signals, thereby improving the scope of use of the electrode connector 10.

[0034] The pressing member 4 can adopt a combination of a button and a self-locking track, and the self-locking function of the button can be used to press the pressing member 3 against the electrode 5 on the circuit board 2, so that the electrode 5 and the circuit board 2 are electrically connected; a combination of a pressing plate 42 and a cam 41 can also be adopted, and the end of the cam 41 does not coincide with the rotation axis of the cam 41, so that the rotational motion can be converted into a linear motion in the vertical direction, and then the rotational motion of the cam 41 can be converted into a linear motion of the pressing member 3 in the vertical direction, so that the pressing member 3 is close to the circuit board 2 or away from the circuit board 2.

[0035] The electrode connector 10 proposed by the technical solution of the present invention includes a housing 1, a circuit board 2, a pressing member 3, and a pressing member 4. The top of the housing 1 is provided with a relief opening 11, and the side wall of the housing 1 is provided with an insertion opening 12 for inserting or removing the electrode 5 from the housing 1. The surface of the circuit board 2 facing the relief opening 11 is provided with multiple conductive spring pins 21 for electrically connecting to the electrode 5. One end of the pressing member 4 is rotatably connected to the housing 1 and has a first position and a second position. When the pressing member 4 is in the first position, one end of the pressing member 4 applies a tightening force to the pressing member 3 to clamp and tighten the electrode 5 to the multiple conductive spring pins 21 of the circuit board 2, ensuring a stable electrical connection between the electrode 5 and the circuit board 2. When the pressing member 4 is in the second position, the tightening force applied by one end of the pressing member 4 to the pressing member 3 disappears, allowing the electrode 5 to be removed from the insertion opening 12. This allows the electrode 5 to be separated from the electrode connector 10. This electrode connector 10 can achieve rapid removal of the electrode 5 without damaging the insertion and removal points of the electrode 5, saving consumables costs.

[0036] In the embodiment of the present invention, the pressing member 4 includes a cam 41 and a pressing plate 42 extending from the cam 41 at a certain angle. The cam 41 is received in the escape opening 11 and abuts against the pressing member 3 .

[0037] In this embodiment, the pressing member 4 includes a cam 41 and a pressing plate 42 extending from the cam 41 at a certain angle. The center of the cam 41 is eccentrically arranged with respect to the rotation axis of the cam 41. The eccentric arrangement converts the rotational motion of the cam 41 into the linear motion of the pressing member 3. Rotating the pressing plate 42 drives the cam 41 to rotate, and the cam 41 drives the pressing member 3 to move closer to or away from the circuit board 2, pressing the electrode 5 against the circuit board 2 or releasing the electrode 5 from the circuit board 2. A rotating flange is provided on the housing 1 or on both edges of the avoidance opening 11, and the cam 41 can rotate about the rotating flange as an axis. When the pressing member 4 is in the first position, the pressing plate 42 is in contact with the outer wall of the housing 1; when the pressing member 4 is in the second position, the pressing plate 42 forms a certain angle with the outer wall of the housing 1.

[0038] In an embodiment of the present invention, a plurality of convex grooves are provided on the surface of the pressing member 3 facing the circuit board 2. When the pressing member 4 is in the first position, the external force applied to the electrode 5 is greater than the friction force generated between the electrode 5 and the pressing member 3 and the plurality of conductive elastic pins 21 due to the fastening force, and the electrode 5 can be detached from the insertion port 12.

[0039] Furthermore, the electrode 5 includes a sheet-shaped FPC, and an opening (not shown) for inserting or disengaging the electrode 5 is provided on the side wall of the abutment member 3 facing the insertion port 12 of the shell 1. This opening is arranged relative to the insertion port 12 on the shell 1. When the pressing member 4 is in the first position, the electrode 5 is fixed horizontally, and this opening serves to position the electrode 5 during horizontal insertion.

[0040] In this embodiment, a plurality of convex grooves are provided on the surface of the pressing member 3 facing the circuit board 2, which can increase the friction between the pressing member 3 and the electrode 5. When the pressing member 4 is in the first position, the external force applied to the electrode 5 in the direction of disengagement from the insertion port exceeds the friction force corresponding to the fastening force, and the electrode 5 can be pulled out. If the operator makes an error in operation, the electrode 5 can be pulled off by itself due to the external force, thereby preventing the mask sheet of the electrode 5 from being torn from the human face and causing pain.

[0041] In the embodiment of the present invention, two guide posts 22 are respectively provided on two opposite sides of the circuit board 2 , and the pressing member 3 can move in the vertical direction along the two guide posts 22 .

[0042] In this embodiment, a guide post 22 is provided on opposite sides of the circuit board 2 to limit the movement path of the pressing member 3 to prevent it from deflecting and causing connection failure.

[0043] In the embodiment of the present invention, at least two first elastic members 23 are provided on the circuit board 2 , and the at least two first elastic members 23 are symmetrically arranged around the plurality of conductive spring pins 21 . When the pressing member 4 is in the first position, the at least two first elastic members 23 abut against the electrode 5 .

[0044] In this embodiment, at least two first elastic members 23 are sandwiched between the fixing seat and the pressing member 3. The at least two first elastic members 23 are symmetrically arranged on both sides of the plurality of conductive elastic pins 21. When the pressing member 4 is in the first position, the first elastic members 23 are in a compressed state. The at least two first elastic members 23 can ensure uniform force between the plurality of conductive elastic pins 21 and the electrode 5. When the pressing member 4 moves from the first position to the second position, the first elastic member 23 recovers its deformation and pushes the pressing member 3 away from the circuit board 2, thereby facilitating the removal of the electrode 5 from the electrode connector 10.

[0045] In an embodiment of the present invention, a limiting portion 31 is protruded from one end of the pressing member 3 away from the insertion port 12 . The limiting portion 31 extends toward the circuit board 2 and is used to limit the depth of the electrode 5 inserted into the insertion port 12 .

[0046] In this embodiment, a limiting portion 31 is protruded from the end of the pressing member 3 away from the insertion port 12. When the electrode 5 is inserted into the electrode connector 10 from the insertion port 12, it will abut against the limiting portion 31 and will not continue to be inserted, thereby controlling the insertion length of the electrode 5.

[0047] In the embodiment of the present invention, one of the two opposite surfaces of the electrode 5 or the pressing member 3 is provided with a protrusion 32 , and the other is provided with a groove 51 . When the pressing member 4 is located at the first position, the protrusion 32 is locked in the groove 51 .

[0048] In this embodiment, one of the electrode 5 or the pressing member 3 is provided with a protrusion 32, and the other is provided with a groove 51. When the pressing member 4 is in the first position, the protrusion 32 can be pressed into the groove 51, thereby fixing the electrode 5 on the pressing member 3 in the horizontal direction, thereby improving the connection strength between the electrode 5 and the pressing member 3.

[0049] In the embodiment of the present invention, the electrode connector 10 further includes a second elastic member, one end of which is connected to the surface of the pressing member 3 facing the electrode 5 , and the other end of which is used to abut against the electrode 5 .

[0050] In this embodiment, one end of the second elastic member abuts against the pressing member 3, and the other end abuts against the electrode 5. When the pressing member 4 is in the first position, the protrusion 32 can be pressed into the groove 51, and the second elastic member is in a compressed state. When the pressing member 4 is in the second position, the second elastic member recovers its deformation and pushes the electrode 5 off the pressing member 3, so that the electrode 5 can be more conveniently removed from the electrode connector 10.

[0051] In an embodiment of the present invention, a first magnetic member 421 is provided at one end of the pressing member 4 away from the avoidance opening 11, and a second magnetic member 13 is provided on the outer wall of the shell 1. When the pressing member 4 is in the first position, the first magnetic member 421 is magnetically connected to the second magnetic member 13.

[0052] In this embodiment, a first magnetic component 421 is provided at the end of the pressing member 4 away from the avoidance opening 11, and a second magnetic component 13 is provided on the outer wall of the shell 1. When the pressing member 4 is in the first position, the first magnetic component 421 is magnetically connected to the second magnetic component 13, which can further tighten the pressing member 4 and prevent the pressing member 4 from being accidentally opened, causing the pressing member 3 to separate from the circuit board 2, and then causing the electrode 5 to fall off and the electrical connection to fail.

[0053] The present invention further provides a radiofrequency treatment device, comprising the electrode connector 10 as described above and an electrode 5 for radiofrequency and / or electrical stimulation treatment, wherein the electrode connector 10 is detachably connected to the electrode 5 .
