[0064] First embodiment:

[0065] Reference Figure 1 and Figure 3-Figure 8 The electrode wire connection device includes a cable 20 and a connector 10 connected to each other. The connector 10 is used to electrically connect to the electrode wire 30, and the electrode wire 30 can be implanted in the body. The electrode wire connection device also includes a plug 40 connected to the cable 20. The plug 40 is used to connect to an external device, such as an in vitro programmer. The electrode wire connection device in this embodiment controls the conductive spring 12 to enter and exit the electrode channel 14 through a push-type switch component 13. The orientation description involved in this embodiment is based on the top of the electrode channel 14 located in the accommodating cavity 111 as a reference direction.

[0066] There are multiple conductive springs 12 arranged at intervals along the electrode channel 14, and each conductive spring 12 is set through the spring slot 151. Each conductive spring 12 is independent of each other and is less affected by errors such as assembly and pressing. The conductive spring 12 includes a U-shaped elastic portion 121, one side of the elastic portion 121 continues to extend through the spring slot 151 and forms a connecting portion 123, and the other side is folded outward to extend to form a fixing portion 124. The extension direction of one side and the other side of the elastic portion 121 is perpendicular or nearly perpendicular to its elastic direction. An arc-shaped abutment portion 122 is also provided between the connecting portion 123 and the elastic portion 121, and the arc-shaped abutment portion 122 is bent toward the fixing portion 124, and the initial position of the arc-shaped abutment portion 122 is located in the electrode channel 14. When the conductive spring 12 passes through one side of the spring slot 151 and bends, the arc-shaped abutment portion 122 moves out of the electrode channel 14, and when it resumes, it moves toward the electrode channel 14 and enters the electrode channel 14. A plurality of first slots 161 are provided through the circuit board 16, and the fixing portion 124 of the conductive spring 12 is inserted and fixed in the first slots 161 and is electrically connected to the circuit board 16. The conductive spring 12 is provided in the accommodating cavity 111, and the opening of the U-shaped structure is perpendicular to the pressing direction of the switch assembly 13. When the switch assembly 13 is pressed, the opening of the elastic portion 121 becomes smaller, so that the conductive spring 12 is partially moved, and the connection stability between the conductive spring 12 and the circuit board 16 is ensured. The conductive spring 12 can also maintain close contact with the contact point of the electrode wire in the pressed state through the elastic portion 121, which effectively improves the stability of the electrical connection.

[0067] In this embodiment, the switch assembly 13 drives the connecting portion 123 to move downward and reset by moving up and down, thereby enabling the arc-shaped abutting portion 122 to move between the electrode channel 14 and the spring slot 151 to achieve the opening and closing of the electrode channel 14. Figure 3-Figure 5 When the electrode wire 30 needs to be connected, the arc-shaped contact portion 122 is moved downward to the outside of the electrode channel 14 by controlling the switch assembly 13, so that the electrode channel 14 is opened, and the electrode wire 30 can smoothly extend into or withdraw from the electrode channel 14. After the electrode wire 30 extends into the electrode channel 14, the switch assembly 13 moves upward, and the arc-shaped contact portion 122 moves toward the direction of the electrode channel 14 until it abuts against the electrode wire 30. After the electrode wire 30 withdraws from the electrode channel 14, the switch assembly 13 moves upward, and the electrode channel 14 is closed again.

[0068] After the electrode wire 30 extends into the electrode channel 14, the arc-shaped abutting portion 122 abuts against the electrode wire 30 and realizes electrical connection between the conductive spring 12 and the electrode wire 30. The arc surface of the arc-shaped abutting portion 122 helps to increase the contact area between the conductive spring 12 and the electrode wire 30, and the arc-shaped abutting portion 122 maintains close contact with the electrode wire 30 through the elastic force of the elastic portion 121, thereby improving the stability of the connection between the electrode wire 30 and the connector 10 or the conductive spring 12.

[0069] Reference Figure 3-Figure 6 , an adapter 15 connected to the shell 11 is arranged in the accommodating chamber 111. The electrode channel 14 and the spring slot 151 are formed between the adapter 15 and the shell 11, and the conductive spring 12 and the circuit board 16 are fixed in the accommodating chamber 111 by the adapter 15. The switch assembly 13 of this embodiment includes an operating member 131, a linkage member 132 and a reset member 133. The linkage member 132 and the reset member 133 are arranged in the accommodating chamber 111, and the reset member 133 is arranged below the direction in which the linkage member 132 is pressed, and the operating member 131 passes through the shell 11 and abuts against the top surface of the linkage member 132. When the operator presses the operating member 131 downward, the linkage member 132 can be driven to move downward, and the reset member 133 is squeezed and elastically deformed. After releasing the operating member 131, the reset member 133 returns to its original state and drives the linkage member 132 and the operating member 131 to move upward to achieve reset. The conductive spring 12 is connected to the linkage member 132 , and the movement and reset of the linkage member 132 can drive the arc-shaped abutting portion 122 of the conductive spring 12 to move and reset between the electrode channel 14 and the spring slot 151 , thereby freely controlling the connection between the electrode wire 30 and the connector 10 .

[0070] Specifically, refer to Figure 6 , a mounting through hole 113 is provided on the shell 11, and the operating member 131 extends into the accommodating cavity 111 through the mounting through hole 113. The operating member 131 is a block-shaped structure with an opening at the bottom, and the four corners of the bottom are folded to form a limiting portion 1311. The size of the limiting portion 1311 is larger than the size of the mounting through hole 113 to prevent the operating member 131 from falling off from the mounting through hole 113. A baffle 116 is also provided below the mounting through hole 113 to prevent the operating member 131 from being completely entered into the accommodating cavity 111 due to excessive pressure. Therefore, the operating member 131 is movably connected to the shell 11 through the limiting portion 1311 and the baffle 116, which is convenient for the operator to operate.

[0071] Reference Figure 3-Figure 6 , the linkage member 132 is located on one side of the electrode channel 14, that is, the linkage member 132 is located on one side of the adapter 15 and the conductive spring sheet 12, and is located on the side away from the opening of the first groove 153, so as to connect the connecting portion 123 of the conductive spring sheet 12. The vertical portion of the linkage member 132 is provided with a plurality of second slots 1321 with openings facing the conductive spring sheet 12. The end of the connecting portion 123, that is, the end away from the arc-shaped abutting portion 122 is inserted into the second slot 1321. The groove wall below the second slot 1321 is an inclined surface, so that the space on the side of the second slot 1321 away from the conductive spring sheet 12 is larger. When the conductive spring sheet 12 moves downward, the connecting portion 123 changes from a horizontal state to an inclined state. The second slot 1321 with a larger space can accommodate the connecting portion 123 when it is fitted and tilted, so as to avoid the connecting portion 123 and the second slot 1321 from abutting against each other and bending.

[0072] The reset member 133 is in contact with the bottom of the linkage member 132. The reset member 133 can drive the linkage member 132 to move upward to reset the multiple conductive springs 12. The top of the linkage member 132 and the bottom of the reset member 133 are respectively in contact with the inside of the shell 11, thereby strengthening the stability of the connection between the linkage member 132 and the reset member 133, and optimizing the internal space arrangement of the accommodating cavity 111. The structure of the reset member 133 is an incompletely closed triangular spring. The opening of the reset member 133 faces the linkage member 132 and is in contact with the bottom of the linkage member 132. The reset member 133 with a triangular structure helps to increase the overall stability of the switch assembly 13. At the same time, the structure is relatively flat and can be installed in a smaller space, thereby improving the space utilization rate in the accommodating cavity 111 and making the structure compact.

[0073] When the operating member 131 is pressed, the linkage member 132 is driven by the operating member 131 to move downward and press the reset member 133 downward. At the same time, the linkage member 132 drives the conductive spring 12 to move downward to the bottom of the electrode channel 14, so that the electrode wire 30 can be inserted into the electrode channel 14. When the operating member 131 is released, the reset member 133 drives the linkage member 132 to move upward, and the arc-shaped abutment portion 122 of the conductive spring 12 is electrically connected to the electrode wire 30 in the electrode channel 14 or moves back into the electrode channel 14. In this way, the operating member 131, the linkage member 132 and the reset member 133 cooperate with each other to realize the movement or rebound of the conductive spring 12 under the pressure control. The push-type switch assembly 13 is relatively convenient to operate, and can timely control the connection and disconnection between the electrode wire 30 and the connector 10, thereby improving the safety of the electrode wire connection device when in use. In this embodiment, the reset member 133 and the elastic portion 121 of the conductive spring 12 form a double elastic force, which can make the connection between the connector 10 and the electrode wire 30 more stable and reliable.

[0074] Reference Figure 3-Figure 4 , Figure 6 , a partition plate 17 is also vertically arranged in the shell 11, and the linkage member 132 and the reset member 133 are limited in the accommodating cavity 111 on one side of the partition plate 17. The adapter 15 and the circuit board 16 are located in the accommodating cavity 111 on the other side of the partition plate 17. The height of the partition plate 17 is lower than the height of the adapter 15, and the connecting portion 123 of the conductive spring 12 crosses the partition plate 17 and is connected to the linkage member 132. The partition plate 17 and the shell 11 surround and limit the linkage member 132 and the reset member 133, avoiding the displacement between the linkage member 132 and the reset member 133 when moving up and down, thereby increasing the stability of the overall structure of the switch assembly 13. At the same time, the provision of the partition plate 17 makes the structural arrangement in the accommodating cavity 111 more neat, thereby improving the utilization rate and functionality of the space. It can be understood that the size of the partition plate 17 can be adjusted and arranged according to the specific structure and size.

[0075] Reference Figure 9-12 The top of the adapter 15 is provided with a first semicircular groove 152 along the length direction, and the inner side of the shell 11 is provided with a second semicircular groove 112. The electrode channel 14 is formed by splicing the first semicircular groove 152 and the second semicircular groove 112. The shell 11 is provided with a connecting through hole 114 that is in communication with the electrode channel 14, and the connecting through hole 114 is used for the electrode wire 30 to pass through the shell 11 to extend into the electrode channel 14. The spring slot 151 is provided on the adapter 15 and is connected to the first semicircular groove 152. The spring slot 151 includes a first part 1511 and a second part 1512. The first part 1511 is located below the first semicircular groove 152 and is through-set along the width direction of the adapter 15. The second portion 1512 is disposed on both sides of the first semicircular groove 152 . The second portion 1512 is a straight groove structure with an open top, and the first portion 1511 is completely connected to the second portion 1512 , thereby enabling the conductive spring 12 to penetrate the spring groove 151 and retain sufficient moving space for the conductive spring 12 .

[0076] Reference Fig.12 A first groove 153 with a lateral opening is further provided below the spring slot 151, and the circuit board 16 is limitedly disposed in the first groove 153. The bottom end portion of the first groove 153 extends downward to form a second groove 154, so as to facilitate the connection between the circuit board 16 and the cable 20 and the distribution of the wires, further improve the space utilization, and improve the reliability and aesthetics of the overall structure.

[0077] It is understandable that the diameter of the electrode channel 14 is equal to the size of the electrode wire 30 or slightly larger than the size of the electrode wire 30 to prevent the electrode wire 30 from shaking when it is inserted into the electrode channel 14. In addition, the number and position of the conductive springs 12 correspond to the number and position of the contacts of the electrode wire 30, and the position of the spring slot 151 corresponds to the position of the contact on the electrode wire 30, thereby ensuring the success rate of the connection between the conductive spring 12 and the electrode wire 30. In this embodiment, the electrode wire 30 is an eight-contact structure, and the number of the conductive springs 12 and the number of the spring slots 151 are eight respectively. In some other embodiments, corresponding to the electrode wire with a four-contact structure or a sixteen-contact structure, the number of the conductive springs 12 and the number of the spring slots 151 are set to four and sixteen respectively.

[0078] Further, refer to Figure 6 and Fig.11The surface of the housing 11 is also provided with a visual window 115. The visual window 115 is interconnected with the electrode channel 14, and a limiting through hole 141 is provided at the end of the electrode channel 14. The size of the limiting through hole 141 is smaller than the size of the electrode channel 14, that is, smaller than the size of the electrode wire 30. The position of the visual window 115 corresponds to the end of the electrode channel 14, so as to facilitate observation of the plugging condition of the electrode wire 30 and ensure accurate connection between the electrode wire 30 and the conductive spring 12.

[0079] Reference Fig.13 The linkage member 132 is an inverted L-shaped structure as a whole, and its top surface area is relatively large, which can effectively increase the contact area between the operating member 131 and the linkage member 132 to ensure the stability of the overall structure.

[0080] The electrode wire connection device of this embodiment connects the spring clip groove where the conductive spring clip is located with the electrode channel, and connects the conductive spring clip with the push-type switch assembly, and the conductive spring clip is partially in the electrode channel. When the operating member of the switch assembly is pressed, part of the conductive spring clip moves to the bottom of the electrode channel so that the electrode wire can be smoothly inserted into the electrode channel. After releasing the operating member, the conductive spring clip rebounds upward to be electrically connected to the contact point of the electrode wire. The push-type switch assembly is simple to operate and has a stable structure. In this embodiment, the conductive spring clip can also maintain close contact with the electrode wire through its own elastic force, effectively improving the stability of the electrical connection, making the electrode wire test convenient, simple, accurate and effective. In the present invention, the partial movement of the conductive spring clip can also be understood as the bending and recovery of one side of the arc-shaped abutment portion of the U-shaped elastic portion.

The conductive spring 12 and the circuit board 16 of this embodiment have the same structure as the conductive spring 12 and the circuit board 16 in the above embodiment, and will not be repeated here. The orientation description involved in this embodiment is based on the top of the adapter 15' located in the accommodating cavity 111 as the reference direction.

[0083] Reference Figure 2 , Figure 14-18The electrode wire connection device includes a cable 20 and a connector 10 connected to each other, and the connector 10 is used to electrically connect with the electrode wire 30. The electrode wire connection device also includes a plug 40 connected to the cable 20, and the plug 40 is used to connect with an external device, such as an in vitro programmer. The connector 10 includes an adapter 15' integrally formed on the inner side of the shell 11, and the electrode channel 14 and the shrapnel slot 151' are connected to each other and arranged on the adapter 15'.

[0090] Reference Figure 14-16 , Fig.19The switch assembly 13' of this embodiment includes a linkage member 132', a slider 134 and a connector 135. The linkage member 132' is disposed in the accommodating chamber 111 and is located on one side of the electrode channel 14 and the circuit board 16. Two vertical limit blocks 18 are also relatively disposed in the accommodating chamber 111. The linkage member 132' is movable up and down between the two limit blocks 18. A vertical third groove 181 is disposed on one side of the two limit blocks 18 close to the linkage member 132', and clamping blocks 1323 that cooperate with the third groove 181 are disposed on both sides of the linkage member 132'. The linkage member 132' can stably move up and down in a straight line direction through the limit cooperation between the clamping blocks 1323 and the third groove 181.

[0091] The slider 134 is movably disposed on the housing 11, the connecting member 135 and the linkage member 132' are disposed in the accommodating cavity 111, and the slider 134 and the linkage member 132' are connected via the connecting member 135. The linkage member 132' is connected to the conductive spring sheet 12, and the linkage member 132' is controlled to move by operating the slider 134 to drive the conductive spring sheet 12 to partially bend and restore, thereby freely controlling the connection and disconnection between the conductive spring sheet 12 and the electrode wire 30.

[0092] The linkage member 132' is provided with an inclined guide rail 1322 and a plurality of second slots 1321' with lateral openings. The ends of the connection parts 123 of the plurality of conductive spring sheets 12, i.e., the ends of the connection parts 123 away from the arc-shaped abutting parts 122, are respectively inserted into the plurality of second slots 1321', so that the arc-shaped abutting parts 122 of the conductive spring sheets 12 can move with the linkage member 132'. The inclined guide rail 1322 is arranged below the second slots 1321'. The inclined guide rail 1322 includes a first fixing part 13221, a second fixing part 13222 and a transition part 13223. The first fixing part 13221 and the second fixing part 13222 are arranged horizontally, and the position of the first fixing part 13221 is higher than the position of the second fixing part 13222. The transition part 13223 is arranged obliquely and connectedly between the first fixing part 13221 and the second fixing part 13222. The connecting member 135 moves laterally and drives the linkage member 132 ′ to move up and down through the inclined guide rail 1322 .

[0093] The connecting member 135 is arranged between the linkage member 132' and the housing 11. It is understandable that the circuit board 16 is located below the electrode channel 14, so the connecting member 135 is arranged on the side of the linkage member 132' away from the electrode channel 14. A guide rod 136 is arranged on one side of the connecting member 135, and the guide rod 136 is connected to the inclined guide rail 1322. The bottom of the first fixing part 13221 and the top of the second fixing part 13222 are respectively provided with arc surfaces that cooperate with the guide rod 136, which helps to limit and fix the guide rod 136 in the first fixing part 13221 or the second fixing part 13222, prevent the guide rod 136 from sliding randomly, and maintain the stability of the overall structure. When the guide rod 136 moves from the first fixed part 13221 to the second fixed part 13222, the linkage part 132' moves upward, the conductive spring sheet 12 returns to its original state from the bent state, and the arc-shaped abutment part 122 moves toward the electrode channel 14. When the guide rod 136 moves from the second fixed part 13222 to the first fixed part 13221, the linkage part 132' moves downward, the conductive spring sheet 12 bends, and the arc-shaped abutment part 122 moves out of the electrode channel 14.

[0094] The electrode wire connecting device of this embodiment controls the connection and disconnection between the conductive spring sheet and the contact point of the electrode wire through a sliding switch assembly. The switch assembly converts the horizontal movement of the slider into the up and down movement of the linkage part through an inclined guide rail, thereby driving the part of the conductive spring sheet located in the electrode channel to move up and down, thereby controlling the connection and disconnection between the electrode wire and the conductive spring sheet. The conductive spring sheet is provided with an elastic part. When electrically connected to the electrode wire, the elastic part can provide a certain pressure to make the connection between the conductive spring sheet and the electrode wire more stable, thereby effectively improving the stability of the electrical connection.
