The utility model discloses a design includes a plurality of specific implementation schemes, and different implementation schemes respectively have technical or applied the emphasis, and different implementation schemes can make up the collocation to satisfy different application scenes, solve different application demands. The following description of specific embodiments is, therefore, not to be taken in a limiting sense, as the invention is intended to be limited to the precise embodiments disclosed.

Hereinafter, various exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

The utility model discloses a connection structure of wire and electrode ring specifically as follows:

as shown in fig. 1, a metal ring 401 is first sleeved on one end of the lead 301, and the metal ring 401 is riveted. The wire 301 is made of MP35N material. The diameter of the wire 301 is 0.1mm to 1mm, preferably 0.12mm to 0.88mm, and the length of the wire 301 is 10cm to 400cm, preferably 12cm to 95cm. The metal ring 401 has an outer diameter of 0.3mm to 3mm, a wall thickness of 0.01mm to 1mm, and a length of 0.5mm to 10mm, preferably an outer diameter of 0.8mm to 2.5mm, a wall thickness of 0.1mm to 0.8mm, and a length of 0.8mm to 8mm. Then, as shown in fig. 2, the swaged metal ring 401 has an arc shape and a curved surface corresponding to the inner surface of the electrode ring 501. The metal ring 401 is made of a medical metal material capable of passing nuclear magnetism, such as platinum-iridium alloy, titanium alloy and the like, and is machined according to a specific size. In some embodiments, the riveted metal ring 401 can have other shapes that increase the surface area of the wire to electrode ring weld. In other embodiments, other metal materials capable of increasing the surface area of the welding point between the lead and the electrode ring can be introduced between the lead and the electrode ring, or the metal ring is riveted into other shapes capable of increasing the surface area of the welding point between the lead and the electrode ring. For example, small metal pieces of various shapes can be incorporated.

Then, the electrode ring 501 is fitted over the metal ring 401 so that the arc-shaped metal ring is fitted to the inner surface of the electrode ring after caulking and the contact area between the two is increased as much as possible. The swaged metal ring 401 is welded to the inner surface of the electrode ring 501, thereby completing the electrical connection of the lead wire 301 to the electrode ring 501. The welding method here can be selected from soldering, resistance welding or laser welding.

The utility model discloses an above-mentioned wire and electrode ring's connection structure's favourable effect as follows:

since a material such as MP35N as a wire has poor soldering property by itself, it is more difficult to secure the soldering reliability if its soldering point is small. After the riveted metal ring is introduced between the lead and the electrode ring, the contact area of the welding part can be obviously improved, and the welding firmness is further enhanced.
