Abstract
Official abstract text for this publication.
A wiring module is directed to a wiring module configured to be attached to a plurality of power storage elements having electrode terminals. The wiring module includes: a plurality of busbar units: and wires connected to the busbar units. Each of the busbar units includes: a busbar connected to the electrode terminals; a circuit board; and a fixing means configured to fix the circuit board to the busbar. A conductive path is routed on the circuit board, and the conductive path includes: a connection land electrically connected to the busbar; and a wire land soldered to the corresponding wire. The busbar includes a crimping part that fixes the wire, and the wire is interposed between the crimping part and the circuit board.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A wiring module configured to be attached to a plurality of power storage elements having electrode terminals, the wiring module comprising: a plurality of busbar units; and a corresponding wire connected to each of the busbar units, wherein each of the busbar units includes: a busbar connected to the electrode terminals; a circuit board including a fixing part and a first surface; and a fixer configured to fix the circuit board to the busbar, a conductive path is routed on the circuit board, the conductive path includes: a connection land electrically connected to the busbar; and a wire land formed on the first surface and soldered to the corresponding wire, the busbar includes a crimping part that fixes the corresponding wire, the corresponding wire is interposed between the crimping part and the circuit board, wherein the fixing part holds and fixes the corresponding wire in cooperation with the crimping part, and wherein the fixing part is in contact with the corresponding wire on the first surface. 2 . The wiring module according to claim 1 , wherein the circuit board has a second surface located on a side opposite to the first surface, and the fixing part is in contact with the busbar on the second surface. 3 . The wiring module according to claim 1 , wherein the circuit board includes a cutout formed in the vicinity of the crimping part. 4 . The wiring module according to claim 3 , wherein the crimping part is disposed inside the cutout. 5 . The wiring module according to claim 1 , further comprising a protector configured to hold the busbars, wherein the circuit boards have a clearance between the circuit boards and the protector. 6 . The wiring module according to claim 1 , wherein the conductive path includes a chip fuse provided between the connection land and the wire land. 7 . The wiring module according to claim 1 , wherein the busbar has a first fixation hole, the circuit board has a second fixation hole, the fixer is a rivet, and the rivet includes a shaft portion configured to be inserted into the first fixation hole and the second fixation hole, and a head portion that is formed at an end of the shaft portion and has a diameter greater than hole diameters of the first fixation hole and the second fixation hole. 8 . The wiring module according to claim 1 , wherein the wiring module is a vehicular wiring module configured to be electrically attached to the plurality of power storage elements mounted on a vehicle.
