In this case, for example, it is possible to assemble by inserting a rod-like member into the hollow part and opening the pressing member and then engaging, thereby improving the ease of assembling.
  • the inclined surface that forms the concave portion by disposing the members facing each other on the side where the electrode terminals are inserted on the clamping surface of the clamping member with each member.
  • the pressing member may be formed to have a convex portion at a portion corresponding to the concave portion.
  • the pressing member may be an inertia member! /, Or a through hole may be formed on both sides of the convex portion. ! /
  • the pressing member of the present invention having elasticity and having a curved shape can firmly clamp the electrode terminal between the pressing member and the holding member by screwing the holding member to the holding member.
  • the number of parts can be reduced by providing a clamping member on the wall surface of the storage case (cell case).

Abstract

Dispositif de couplage (100) pour coupler électriquement des terminaux d’électrode (3, 4) d’une batterie recouverte d’un film, pourvu d’un élément de mise en sandwich (20) ayant un premier élément (21) et un second élément (22), et d'un élément de pression (30). L’élément de pression (30) presse sur le terminal d’électrode (3) pour une électrode positive et sur le terminal d’électrode (4) pour une électrode négative dans la batterie recouverte d’un film (1) dans une direction dans laquelle les terminaux peuvent entrer en contact les uns avec les autres par pression. Les terminaux sont mis en sandwich par des plans de mise en sandwich (21a, 22a) de l’élément de mise en sandwich (20) en se recouvrant partiellement.
