Figure 3 is an exploded view of the connector of the embodiment of the present utility model. Figure 4 is a schematic diagram of the structure of the switch assembly of the connector of the embodiment of the present utility model in the pressed state. Figure 5 is a schematic diagram of the structure of the switch assembly of the connector of the embodiment of the present utility model after reset.

[0049] Referring to Figures 1 - 5 , the electrode wire connection device of this embodiment includes a cable 10, a connector 20 and a plug 30. The connector 20 and the plug 30 are respectively connected to both ends of the cable 10. The connector 20 is used to connect with the electrode wire, the electrode wire is used for implantation in the body, and the plug 30 is used to connect with external devices such as an external programmer, etc. The connector 20 includes a housing 21, a circuit board 22, a plurality of conductive elastic pieces 23 and a switch assembly 24. An electrode groove 212 and a conductive groove 213 are provided on the outer side of the housing 21. The housing 21 has an accommodation cavity 211 inside, and the electrode groove 212 communicates with the accommodation cavity 211 through the conductive groove 213. The circuit board 22 and the conductive elastic pieces 23 are arranged in the accommodation cavity 211 and connected to the switch assembly 24. The switch assembly 24 includes a button 241 and a connection seat 242. The connection seat 242 is arranged in the accommodation cavity 211, and the circuit board 22 and the conductive elastic pieces 23 are fixed on the connection seat 242. One end of the button 241 extends into the accommodation cavity 211 and is connected to the connection seat 242. The electrode wire connection device of this embodiment can drive the conductive elastic piece 23 to move by controlling the button 241, and thus freely control the connection between the conductive elastic piece 23 and the electrode wire.

[0050] Referring to Figure 4 , a top end of the housing 21 is recessed inward to form the electrode groove 212. The electrode groove 212 is arranged along the length direction of the housing 21. One end of the electrode groove 212 is set as an opening, and the other end is communicated with a slender groove 217. The top and the end far from the electrode groove 212 of the slender groove 217 are set as openings to accommodate and fix a guiding metal wire (not shown in the figure) extending from the electrode wire. The metal guiding wire is used to enhance the rigidity of the electrode wire and facilitate the connection between the electrode wire and the connector 20.

[0051] Referring to Figure 2 and Figure 5, a plurality of conductive grooves 213 are arranged at intervals along one side of the electrode groove 212, and are communicated with the electrode groove 212, and at least part of the bottom of the electrode groove 212 is communicated with the conductive groove 213. The conductive groove 213 penetrates through the groove wall of the electrode groove 212. The conductive groove 213 is longitudinally communicated with the electrode groove 212, and then penetrates through part of the bottom of the electrode groove 212, so that the electrode groove 212 is communicated with the accommodation cavity 211. The bottom of the electrode groove 212 is communicated with the conductive groove 213, so that the conductive elastic sheet 23 can continue to move towards the electrode wire direction after passing through the conductive groove 213, and then abuts against the contact point of the electrode wire, realizing a stable connection between the conductive elastic sheet 23 and the electrode wire.

[0052] Referring to Figure 6 and Figure 7 , the connector 20 further includes a fixing member 25. The fixing member 25 is arranged in the electrode groove 212 and is located at one end of the electrode groove 212 away from the slender groove 217, and can assist in limiting and fixing the electrode wire. The fixing member 25 includes a U-shaped clamping portion 251 and a connecting portion 252. The connecting portion 252 extends into the accommodation cavity 211 and is connected to the housing 21. The clamping portion 251 can clamp and fix the electrode wire to fix the electrode wire in the electrode groove 212. A fixing groove 216 cooperating with the clamping portion 251 is arranged in the electrode groove 212, and a fixing through hole 219 communicated with the accommodation cavity 211 is arranged at the bottom of the fixing groove 216. The connecting portion 252 is an inverted umbrella-shaped structure, including a rod portion 2521 connected to the clamping portion 251 and an inverted triangular crown portion 2522. After the crown portion 2522 passes through the fixing through hole 219, it can be clamped in the accommodation cavity 211, thereby realizing the connection between the fixing member 25 and the housing 21. Optionally, the fixing member 25 can be made of elastic silicone or rubber and the like, which is convenient for clamping and disassembling the electrode wire, and is also convenient for the installation and disassembly between the connecting portion 252 and the housing 21.

[0053] Referring to Figure 3 and Figure 8 , the conductive elastic sheet 23 and the circuit board 22 are arranged relatively perpendicular to each other. A slot 221 is arranged on the circuit board 22. The conductive elastic sheet 23 is a U-shaped structure with an opening downward. The vertical part on one side continues to extend and is inserted and fixed in the slot 221, and the vertical part on the other side is used to abut against the contact point of the electrode wire. The bent part of the U-shaped structure has a certain elasticity. When the conductive elastic sheet 23 abuts against the contact point, the vertical part can apply a continuous pressure to the contact point, thereby improving the reliability of the contact between the conductive elastic sheet 23 and the contact point.

[0054] It can be understood that the number and position of the conductive elastic pieces 23 correspond to the number and position of the contacts of the electrode wire, and the position of the electrode groove 212 corresponds to the position of the contacts on the electrode wire, thereby ensuring the success rate of the connection between the conductive elastic piece 23 and the electrode wire. In this embodiment, the electrode wire has an eight-contact structure, and the number of the conductive elastic pieces 23 and the number of the electrode grooves 212 are both eight. In some other embodiments, for the electrode wire corresponding to a four-contact structure or a sixteen-contact structure, the number of the conductive elastic pieces 23 and the number of the electrode grooves 212 are correspondingly set to four or sixteen.

[0055] Referring to Figure 2 and Figure 8 , the conductive elastic piece 23 and the circuit board 22 are connected to the connection seat 242 by clamping the circuit board 22 in the limiting groove 243, and the switch assembly 24 can drive the conductive elastic piece 23 to move between the accommodating cavity 211, the conductive groove 213 and the electrode groove 212. The top end of the connection seat 242 is provided with a limiting groove 243, that is, one end of the connection seat 242 close to the electrode groove 212. The limiting groove 243 has a lateral opening, and this opening faces the side of the connection seat 242 where the button 241 is provided. The circuit board 22 extends into the limiting groove 243 from this lateral opening, and the size of the limiting groove 243 is matched with the size of the circuit board 22 to limit and fix the circuit board 22. A clamping groove 244 is further provided at the top end of the limiting groove 243, and the clamping groove 244 communicates with the limiting groove 243 longitudinally (vertically, that is, perpendicular to the moving direction of the button 241) to accommodate the conductive elastic piece 23 on the circuit board 22. The clamping groove 244 also has a top opening and a lateral opening, and the lateral opening of the clamping groove 244 and the lateral opening of the limiting groove 243 are in the same direction and communicate with each other. That is to say, the clamping groove 244 penetrates through the top end of the limiting groove 243 and has the same lateral opening as the limiting groove 243 to simultaneously push the circuit board 22 and the conductive elastic piece 23 into the limiting groove 243 and the clamping groove 244.

[0056] Referring to Figure 2 and Figure 8 , a contact plate 245 is vertically provided on one side of the clamping groove 244, and a convex block 2451 is provided on the contact plate 245. The conductive elastic piece 23 abuts against the convex block 2451 to enhance its own stability. The contact plate 245 is provided on the side of the conductive elastic piece 23 away from the electrode groove 212, and can provide a certain supporting force for the conductive elastic piece 23 when the conductive elastic piece 23 abuts against the electrode wire, and improve the contact stability between the conductive elastic piece 23 and the electrode wire. Referring to Figure 9 , a weight-reducing hole 247 is further provided on the connection seat 242 to reduce the weight, which helps to reduce the rebound time of the connection seat 242, thereby improving the response speed of the switch assembly 24 and ensuring that the conductive elastic piece 23 and the electrode wire can be connected quickly and stably.

[0057] Referring to Figure 2 ,Figures 10 - 11 One end of the button 241 extends into the accommodation cavity 211 and is connected to the connection base 242. The button 241 is located on the side of the conductive elastic sheet 23 away from the conductive groove 213. When the button 241 is pressed into the accommodation cavity 211, the connection base 242 can drive the conductive elastic sheet 23 to move from the electrode groove 212 into the electrode groove 212 or the accommodation cavity 211. An installation through hole 218 is also provided on the housing 21, and the button 241 extends into the accommodation cavity 211 through the installation through hole 218 and is connected to the connection base 242. An elastic reset member 246 abuts against the side of the connection base 242 opposite to the button 241. When the button 241 is pressed, the connection base 242 moves and drives the conductive elastic sheet 23 to move from the electrode groove 212 to the accommodation cavity 211, and at the same time, the elastic reset member 246 is squeezed and deformed. After the button 241 is released, the elastic reset member 246 returns to its original shape and drives the connection base 242 and the button 241 to move back to their original positions, and at the same time drives the conductive elastic sheet 23 to move into the electrode groove 212. In this embodiment, the elastic reset member 246 and the U-shaped conductive elastic sheet 23 form a double-elastic structure. After the conductive elastic sheet 23 abuts against the electrode wire, the conductive elastic sheet 23 exerts a force on the electrode wire, and the elastic reset member 246 exerts a force on the connection base 242. The directions of the two forces are the same, ensuring the reliability of the connection between the connector 20 and the electrode wire.

[0058] Refer to Figure 12 A groove 2421 is provided on the connection base 242, and a limiting rod 26 is provided on the inner side of the housing 21 near the groove 2421. The position of the limiting rod 26 corresponds to the position of the groove 2421. The elastic reset member 246 is arranged in the groove 2421 and sleeved on the limiting rod 26. When the elastic reset member 246 is squeezed and deformed, it can deform along the limiting rod 26, thereby preventing the elastic reset member 246 from shifting during the compression or recovery process, effectively improving the stability of the switch assembly 24.

[0059] When the connecting device of this embodiment connects the electrode wire, first press the button 241 to make the conductive elastic sheet 23 withdraw from the electrode groove 212 to open the electrode groove 212. After the electrode wire is placed in the electrode groove 212, release the button 241, and the conductive elastic sheet 23 moves into the electrode groove 212 to clamp and conduct the electrode wire. The structure of this electrode wire connecting device is simple, the operation is convenient, and the overall structure is highly reliable. In addition, the electrode groove 212 is arranged on the outer side of the housing 21. When the electrode wire is placed in the electrode groove 212, all the contact parts are exposed on the outside. Therefore, the operator can clearly observe the connection situation between the contact and the conductive elastic sheet 23 and make adjustments, effectively improving the stability and safety of the connection between the device and the electrode wire, and reducing phenomena such as poor electrical contact between the electrode wire and the connecting device or the electrode wire not being clamped tightly.

[0060] Refer to Figures 10 - 12, two limiting members 214 are further provided in the accommodation cavity 211. The connecting seat 242 is located between the two limiting members 214, and a relatively small distance is maintained between the connecting seat 242 and the limiting members 214. The limiting members 214 can ensure that the connecting seat 242 moves in a straight line without increasing the friction force between the limiting members 214 and the connecting seat 242, thereby ensuring that the conductive elastic piece 23 can accurately pass through the conductive groove 213 and connect with the contact on the electrode wire. A hollow portion 2141 is further provided on the limiting member 214, and the cable 10 can pass through the hollow portion 2141 and be connected to the circuit board 22.

[0061] Referring to Figure 13 and Figure 14 , an auxiliary member 215 is further provided in the accommodation cavity 211. The auxiliary member 215 abuts against the lower side of the connecting seat 242. A slider 2151 with a relatively small area is provided on the surface of the auxiliary member 215 that abuts against the connecting seat 242. The bottom surface of the connecting seat 242 only abuts against the slider 2151, which can effectively reduce the friction force received when the connecting seat 242 moves, make the reaction speed of the switch assembly 24 more sensitive, and at the same time can extend the service life of the switch assembly 24. In this embodiment, two auxiliary members 215 are provided in the accommodation cavity 211, and two sliders 2151 are arranged at intervals on each auxiliary member 215 to ensure the force balance of the connecting seat 242. Two stoppers 27 are further provided between the two auxiliary members 215. The stoppers 27 are fitted outside the groove 2421. The stoppers 27 are used to block the notch of the groove 2421 to prevent the elastic reset member 246 from coming out of the groove 2421.

[0062] The electrode wire connection device of this embodiment controls the movement of the conductive elastic piece by connecting the conductive elastic piece with the movable switch assembly, and further realizes the free control of the on-off of the electrical connection between the conductive elastic piece and the electrode wire. The bottom of the electrode groove is longitudinally communicated with the accommodation cavity through the conductive groove, so that the conductive elastic piece can further extend into the electrode groove to abut and fix the electrode wire. The utility model improves the stability of the electrical connection between the electrode wire and the conductive elastic piece, effectively improves the accuracy and efficiency of signal transmission, makes the electrode wire test convenient, simple and effective, and helps to accurately judge the position of the electrode wire, the early treatment effect, etc.

[0063] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
