    摘要： This application provides an electrochemical device and an electronic device. The electrochemical device includes: a housing, an insulator, a connecting strip, and a feedthrough connector. The housing defines an accommodation cavity and includes a cover. The cover includes a first wall face oriented toward the accommodation cavity and a second wall face away from the accommodation cavity. The cover includes a first through-hole that runs through the first wall face and the second wall face. The connecting strip is connected to the first wall face, the second wall face, or an inner wall of the first through-hole. A second through-hole of the connecting strip communicates with the first through-hole. The insulator is fitly connected to the connecting strip. The insulator includes a third through-hole communicating with the second through-hole. A first part of the feedthrough connector is fitly connected to a wall face of the insulator, the wall face being away from the connecting strip. The first part covers the third through-hole. One end of a second part of the feedthrough connector is connected to a wall face of the first part, the wall face being oriented toward the connecting strip. Another end of the second part is disposed at the first through-hole, the second through-hole, and the third through-hole separately. The electrochemical device according to this application is characterized by relatively high energy density and mounting precision, and relatively low production cost.

    摘要： Provided is a battery pack. The battery pack includes a battery cell, an input/output terminal to/from which a charging/discharging current of the battery cell is inputted/outputted, and a connector detachably connected to the input/output terminal, wherein the input/output terminal includes a first hollow conductive member protruding in a first direction and a second hollow conductive member protruding to surround an outer periphery of the first hollow conductive member, the connector includes a central guide protruding in a second direction opposite to the first direction and a third hollow conductive member protruding to surround the outer periphery of the central guide, the central guide is fitted into a hollow portion of the first hollow conductive member, and the third hollow conductive member is fitted into a recess space between the first and second hollow conductive members and is electrically connected to the first and second hollow conductive members by interposing an elastic connection member arranged in the recess space. According to an embodiment, a connection structure between an input/output terminal connected to one group of battery cells and a connector connected to the external load, the external charger or another group of battery cells, is enhanced so that a connection structure may be simplified, the number of components and cost may be reduced and the reliability of an electrical connection may be enhanced.
