  • Patent number: 10601017
    Abstract: A conductor module includes a wiring member, a plurality of bus bars, a plurality of locking pieces, and a reinforcing member. A plurality of wirings and through-holes are formed in the wiring member. The bus bar is electrically connected to one of two electrode terminals. The two through-holes are formed in a first opposing region opposing one end face between both end faces of the bus bar opposing each other in a width direction with an electrical connection portion where the bus bar and the wiring are electrically connected interposed therebetween. The locking piece is formed integrally with the bus bar, is arranged in the through-hole, has a distal end positioned radially outward of the through-hole, and fixes the bus bar to the wiring member. The reinforcing member reinforces the wiring member, and is formed to surround the through-hole.

  • Patent number: 10553917
    Abstract: A conductor module includes a wiring member, a plurality of bus bars, and a plurality of locking pieces. The wiring member is formed in a film shape with flexibility, and a plurality of wirings and through-holes are formed therein. The bus bar is electrically connected to one of two electrode terminals. The two through-holes are formed in a first opposing region opposing one end face between both end faces of the bus bar opposing each other in a width direction of the bus bar with an electrical connection portion where the bus bar and the wiring are electrically connected interposed therebetween when viewed from the width direction. The locking piece is formed integrally with the bus bar, is arranged in the through-hole, has a distal end positioned radially outward of the through-hole when viewed from an axial direction of the through-hole, and fixes the bus bar to the wiring member.
