Technical Field

[0001] This utility model relates to the field of electrical connections in medical devices, and in particular to an electrode connection wire. Background Technology

[0002] In the prior art, the electrical connection between the treatment device and the treatment electrode of the electronic or medical device that cooperates with each other is generally a plug-and-socket connection. In the prior art, the electrical connection is mostly achieved by using spring pins and spring pins to clamp the upper and lower clamps to secure the object to be tested. For example, Chinese patent CN201120353548.6 discloses a dual-purpose charging clip, or Chinese patent CN219833042U discloses a direct-plug connector that is easy to assemble. It adopts a shell, a current bar, a clamping spring, a rotating element, and a rod element. The current bar is fixedly installed in the shell, the rotating element is rotatably installed on the first rotating axis of the shell, and the clamping spring is installed on the rotating element. Under the action of the rotating element, the installation stability of the clamping spring is ensured.

Current technologies for electrical connections of planar electrodes are either too cumbersome or too costly, failing to balance cost control, ease of production and assembly, and guaranteed product lifespan and reliability.

At the connection point between the electrode wire connecting terminal 106 and the wire body 102, there is an internal core wire branching structure 105 and a wire SR103. The internal core wire branching structure 105 is used to split one power line in the wire body 102 into multiple power lines. The connection enables electrical connection of one or more interface terminals of the treatment device; wire SR103 serves as the SR between the connecting wire 100 and the connector converter 700, protecting the wire body 102 from excessive bending damage by preventing damage; the internal core wire branching structure 105 and wire SR103 are connected by an anti-rotation structure 104, which secures the wire body 102 after assembling the connector converter 700 housing, preventing internal rotation. The anti-rotation structure 104 and the internal core wire branching structure 105 are implemented using existing structures with similar functions, and will not be described in detail here.

[0053] The converter base shell 200 is used to mount the conductive spring sheet 300, which supports the rotary pressing function. Its material is typically a polymer material such as ABS, PC / ABS, PC, or POM. The conductive spring sheet 300 forms an electrical connection with the planar electrode when the rotating shaft 400 is pressed down. Its material is typically a flexible material such as stainless steel, 65 manganese steel, or beryllium copper. The thickness of the conductive spring sheet 300 ranges from 0.2mm to 1.0mm, preferably from 0.35mm to 0.55mm. The conductive spring sheet 300 is connected to the electrode wire connection terminal 106. A heat-shrink tubing 500 is provided at the connection point between the conductive spring sheet 300 and the electrode wire connection terminal 106 for insulation protection. The connection can be achieved by welding. Its material is typically a polyolefin (such as polyethylene PE), polyvinyl chloride (PVC), ethylene-vinyl acetate copolymer (EVA), polyethylene terephthalate (PET), or polyvinylidene fluoride (PVDF).

[0054] As attached Figure 4 As shown, the converter bottom shell 200 includes a conductive spring support surface 201, a bottom shell conductive spring positioning post 202, a bottom shell rotating shaft base 203, a bottom shell rotating shaft base positioning hole 204, a bottom shell conductive spring initial positioning groove 205, a conductive spring elastic transition arm groove 206, a support surface 207, a first electrode wire fixing groove 208, a first electrode wire anti-rotation groove 209, a first hook structure 210, a first limiting groove 211, a first positioning groove 212, and a bottom 213 of the planar electrode insertion cavity;

[0055] A conductive spring support surface 201 is disposed in the connector converter 700 to accommodate a conductive spring 300. A bottom shell conductive spring positioning post 202 is used to position the conductive spring 300, and assists the conductive spring support surface 201 in accommodating the conductive spring 300. One end of the conductive spring support surface 201 is provided with a bottom shell conductive spring initial positioning groove 205, which is used to position the conductive spring 300. The other end of the conductive spring support surface 201 is provided with a conductive spring elasticity guide. The arm groove 206 is used to transition the elasticity of the conductive spring 300, effectively preventing the spring from becoming misaligned due to shaking or falling during its shelf life. The side of the conductive spring elasticity transition arm groove 206 away from the conductive spring support surface 201 is provided with a support surface 207, which is used to accommodate the electrode wire connection terminal 106, i.e., to support the electrode wire connection terminal 106 after the heat shrink tubing 500.

This angle enables the conductive spring support surface 201 to communicate with the support surface 207, effectively avoiding uneven height of the bottom teeth after the spring is assembled.

[0056] The conductive spring support surface 201 has a bottom shell rotating shaft base 203 and a bottom shell rotating shaft base positioning hole 204 on its side, which are used to connect with the rotating shaft 400.

[0057] The bottom shell 200 of the converter is also provided with several first hook structures 210, first limiting grooves 211, and first positioning grooves 212, which are used to cooperate with the upper shell 600 of the converter to achieve assembly positioning and snap-fit ​​fixation;

[0058] An insertion cavity 701 for a planar electrode is provided at the energized point of the connector converter 700; the energized point of the conductive spring support surface 201 serves as the bottom 213 of the insertion cavity for the planar electrode.

[0059] The converter upper shell 600 includes a planar electrode insertion cavity top end 601, a second limiting boss 602, a plurality of second hook structures 603, a second positioning post 604, a second electrode wire anti-rotation groove 605, and a second electrode wire fixing groove 606.

[0060] As attached Figure 5 As shown, the converter upper housing 600 is provided with a planar electrode insertion cavity top part 601. The planar electrode insertion cavity top part 601 and the planar electrode insertion cavity bottom part 213 together constitute a planar electrode insertion cavity 701. The planar electrode insertion cavity 701 is used to insert a planar electrode to realize the electrical connection of the conductive spring 300.

[0061] The converter upper shell 600 is provided with a plurality of second limiting bosses 602, a plurality of second hook structures 603, and a second positioning post 604. The second limiting bosses 602 correspond one-to-one with the first limiting grooves 211, the second hook structures 603 correspond one-to-one with the first hook structures 210, and the second positioning posts 604 correspond one-to-one with the first positioning grooves 212, so as to realize the assembly positioning and snap-fit ​​fixation with the converter bottom shell 200. The converter upper shell 600 is provided with a second electrode wire anti-rotation groove 605 and a second electrode wire fixing groove 606 at the end away from the power supply.

The second electrode wire fixing groove 606 cooperates with the first electrode wire fixing groove 208 to prevent rotation of the wire body 102.

[0062] As attached Figure 6 As shown, the planar electrode is inserted into the insertion cavity 701 of the planar electrode; the rotating shaft 400 presses or releases the planar electrode with the connector converter 700 through its own rotating shaft assembly 401. When the rotating shaft is pressed, the planar electrode forms an electrical connection with the conductive spring inside the converter, and then forms an overall electrical connection with the connecting wire; when the rotating shaft is opened, the electrical connection between the planar electrode and the conductive spring is released, and the planar electrode is disconnected.

[0063] The number of conductive spring contacts is the same as the number of electrode wire connection terminals, and each conductive spring contact corresponds to a separate connection channel; this achieves a single-line connection between the treatment device and the treatment point; in this embodiment, the specific value of the conductive spring contact 300 is not limited and can be arbitrarily set according to actual conditions; as shown in the attached figure. Figure 8 As shown, the conductive spring 300 includes a support fixing arm 301, a connecting protrusion 303, a spring angle 304, a conductive spring positioning hole 305, a conductive spring positioning arm 306, a conductive spring elastic transition arm 307, and a conductive spring connecting end 308.

[0064] The main structure of the conductive spring 300 consists of a support and fixing arm 301 and a spring arm above the support and fixing arm. The spring arm moves closer to or further away from the support and fixing arm 301 when the rotation shaft 400 is pressed or relaxed, and works with the inserted planar electrode to achieve electrical connection or disconnection between the planar electrode and the conductive spring. The support and fixing arm 301 is used to support and fix the bottom of the conductive plane. A connecting protrusion 303 is provided on the side of the support and fixing arm 301 near the planar electrode, which is used to connect the planar electrode and the conductive spring 300, and supports the planar electrode to be electrically connected in either the forward or reverse direction. The connecting protrusion 303 is preferably a whole protrusion, but can be a partial protrusion.

[0065] The end of the elastic arm near the planar electrode is provided with a spring angle 304, which is used for limiting and guiding the insertion of the planar electrode into the conductive spring piece; the angle between the plane containing the spring angle 304 and the plane containing the elastic arm is θ1, and the value of θ1 ranges from 30° to 80°, preferably from 45° to 60°; as shown in the attached figure. Figure 11 As shown, the distance above the thickness of the planar electrode in the insertion cavity 701 is L6, where L6 ≥ 0.2 mm, preferably within the range of 0.5 mm to 1.5 mm; this facilitates the insertion and removal of the planar electrode; and, in conjunction with the design of the θ1 included angle, prevents errors in the placement of the planar electrode and improper insertion, ensuring consistency between the insertion position and the position of the conductive spring.

[0066] The support and fixing arm 301 is provided with a conductive spring piece positioning hole 305, which is used to fix the conductive spring piece on the bottom shell 200 of the converter, that is, to cooperate with the bottom shell conductive spring piece positioning post 202 on the bottom shell 200 of the converter.

[0067] The support fixing arm 301 is provided with a conductive spring piece positioning arm 306 on the side near the planar electrode, which is used to fix the conductive spring piece on the bottom shell 200 of the converter, that is, to cooperate with the bottom shell conductive spring piece initial positioning groove 205 on the bottom shell 200 of the converter.

[0068] The connection between the support arm 301 and the elastic arm is a conductive spring transition arm 307, used for the non-elastic structure of the conductive spring, i.e., the transition between the support arm 301 and the elastic arm, and the conductive spring connection end 308, which cooperates with the conductive spring elastic transition arm groove 206 on the converter bottom shell 200; the distance between the spring angle 304 and the conductive spring elastic transition arm 307 is defined as the elastic arm region L3, where L3 ≥ 15mm; the distance between the fulcrum of the conductive spring rotation axis and the conductive spring elastic transition arm 307 is defined as L4, where L4... The thickness should be ≥5mm, preferably 6mm~20mm, to improve the fatigue life of the conductive spring after repeated opening and closing of the rotating shaft 400; when the planar electrode is not inserted in the bare test, the force of the rotating shaft pressing down should be as close to 0N as possible; the greater the force required when the rotating shaft is pressed down in the bare test, the higher the requirements for the friction resistance of the rotating shaft and the elasticity of the conductive spring; setting the relative position of the rotating shaft and the conductive spring is crucial; the distance between the conductive spring positioning arm 306 and the conductive spring elastic transition arm 307 is defined as L7, which is usually ≥15mm, preferably 10mm~60mm; the distance between the conductive spring positioning arm 306 and the connecting protrusion 303 is defined as L8, where L8 ≥3mm;

[0069] The conductive spring transition arm 307 has a conductive spring connection end 308 on the side away from the planar electrode, which is used to realize the electrical connection between the conductive spring and the electrode wire connection terminal 106.

[0070] As attached Figure 9 and attached Figure 17 As shown, the rotating shaft 400 includes a rotating shaft assembly 401, a conductive spring separator post 402, and a pressing rib 403. The rotating shaft assembly 401 is an integral structure of the rotating shaft 400 and is located at one end of the rotating shaft 400. The rotating shaft assembly 401 is provided with a conductive spring separator post 402, and the conductive spring separator post 402 is provided with a pressing rib 403 to realize the pressing of the planar electrode. The pressing rib should be rounded to facilitate rotation. The effective pressing amount L5 after the pressing rib and the planar electrode are pressed should be ≥0.2mm, preferably in the range of 0.25mm~0.7mm, to effectively ensure the pull-out force of the planar electrode under the pressing state and prevent the planar electrode from falling off during use and causing safety issues. The pull-out force is ≥3N, preferably 10N~25N.

[0071] In some other embodiments of this utility model, the rotating shaft 400 can be implemented by other structures, such as not providing a built-in rotating shaft assembly 401, but using a pin structure to connect the rotating movable part to the converter upper shell 600.

[0072] As attached Figure 7 As shown, a dispensing adhesive 702 is provided in the insertion cavity 701 of the planar electrode. The dispensing adhesive 702 is located at the root of the conductive spring positioning arm 306. After the dispensing adhesive is applied, the bottom of the conductive spring is fixed to be consistent with the bottom shell of the converter, which effectively avoids the situation that the bottom teeth are not the same height after the spring is assembled.
