WIRING MODULE
Document Type and Number:
WIPO Patent Application WO/2024/075689
Kind Code:
A1
Abstract:
Provided is a wiring module 20 to be attached to a battery layered body 11L that is formed by layering a plurality of laminate batteries 11 comprising electrode leads 12, and that comprises a joint part 13 in which the electrode leads 12 of the laminate batteries 11 are overlapped with each other and joined together. The wiring module 20 comprises: a terminal 30; an electrical wire 45 that is connected to the terminal 30; and a protector 50 that holds the terminal 30 and the electrical wire 45. The terminal 30 comprises: a body part 31; a connection part 32 that extends from the body part 31, and that is connected facing the first direction to the electrode leads 12 constituting the joint part 13; and a bent plate part 33 that is connected via a bending part 35 to the body part 31, and that extends in the first direction toward the laminate batteries 11 side. The protector 50 includes: a protector body 51; a recessed part 56 that is recessed in the first direction toward the laminate batteries 11 side with respect to the protector body 51, and that accommodates the bent plate part 33; and at least one deflection piece 62 that extends from the protector body 51, and that is capable of deflective deformation in a second direction orthogonal to the first direction. The deflection piece 62 comprises: a plurality of plate parts 63 that extend in the first direction and that are aligned spaced apart from each other in the second direction; and at least one connection part 64 that connects the end parts in the first direction of two adjacent plate parts 63. The plurality of plate parts 63 include at least a base end-side plate part 63B that is connected to the protector body 51, and a distal end-side plate part 63A that is disposed so as to oppose the terminal 30. The distal end-side plate part 63A comprises an engagement part 65A that is disposed in the recessed part 56, and that engages with the bent plate part 33 from the side opposite the laminate batteries 11 side in the first direction. The plate parts 63 and the connection part 64 are connected alternately to each other from the base end-side plate part 63B to the distal end-side plate part 63A, and due to this configuration, the deflection piece 62 forms a bellows shape.
