Electrochemical device and electronic device

An electronic device comprising an electrochemical device, the electrochemical device comprising:

• a housing, wherein the housing defines an accommodation cavity and comprises a cover, the cover comprises a first surface facing toward the accommodation cavity and a second surface facing away from the accommodation cavity, and the cover comprises a first through-hole running through the first surface and the second surface;
• a connecting strip, connected to the first surface or the second surface or connected to an inner wall of the cover surrounding the first through-hole, wherein the connecting strip comprises a second through-hole communicating with the first through-hole;
• an insulator, fitly connected to the connecting strip, wherein the insulator comprises a third through-hole communicating with the second through-hole;
• and
• a feedthrough connector, comprising a first part and a second part, wherein the first part is fitly connected to a surface of the insulator, the surface of the insulator being away from the connecting strip, the first part covers the third through-hole, one end of the second part is connected to a surface of the first part, the surface of the first part is a surface of the first part facing toward the connecting strip, and the second part extends away from the first part and is partly disposed in the first through-hole, the second through-hole, and the third through-hole.
