The housing member includes a housing body that houses first and second conductive members, a lid body that closes an opening of a second housing chamber of the second conductive member in the housing body, a hinge body as a living hinge therebetween, and a holding mechanism that holds the lid body in the housing body at a closing position, the holding mechanism includes a first engagement holder having an inserted portion, and a second engagement holder having a claw portion.

A power supply device includes a battery cell assembly being an assembly of battery cells each having electrodes, a battery connecting block including a case body including terminal fixing portions connected to each other via flexural deformation portions and a cover fixed to the case body and configured to cover the terminal fixing portions, and lock portions provided to the cover and the case body with intervals in a longitudinal direction. A lock portion other than lock portions located at two end positions in the longitudinal direction is configured to be capable of locking the cover with the case body with a changeable relative lock position of the cover and the case body in the longitudinal direction.

Power supply device

A power supply device () includes a battery cell assembly () being an assembly of battery cells () each having electrodes () and a battery connecting block () including a case body () including an adjacent first and second divided fixing portions () connected to each other via a flexural deformation portion (). The flexural deformation portion () includes a first rising linear portion () having one end fixed to the first divided fixing portion, a second rising linear portion () having one end fixed to the second divided fixing portion, first and second curve portions () bent at the other ends of the first and second rising linear portions () in a direction to come close to each other, and a linear portion () connecting the first and second curve portions to each other.

A fuse cover lockhas a return portion that is inserted through a through hole, which is an engagement portion, so as to be brought into engagement with a step portion. In the return portion that is in engagement with the step portion, an end portion on a side facing a fuse coverin an assembling direction of a fuse holderto the fuse coveris positioned near a circumferential edge of an opening of the through hole.

Fixing structure for fuse holder and fuse cover

A synthetic resin plate () includes a plurality of accommodating parts () which accommodate at least one of bus bars, terminals, and electric wires which are connected to the terminals, hinges () which make first accommodating parts and second accommodating parts of the accommodating parts () connected and relatively movable, and projecting parts which are provided on the top surfaces of peripheral wall parts of the first accommodating parts, and which abut against parts of the second accommodating parts to restrict the movable ranges in the movable directions of the second accommodating parts relative to the first accommodating pans.

Bus bar module accommodating part structure

A power-supply unit and a bus bar module which can reduce die cost of an insulating cover are provided. Each of the two insulating covers is provided so as to cover both a first receiving portion and a second receiving portion. For this reason, the two insulating covers arranged on a plate and aligned in an overlapping direction of a battery can be formed in the same shape and same size.

Bus bar module and power-supply unit

Provided are: a first-group accommodation part () and a second-group accommodation part () in each of which accommodation parts () each of which accommodates at least one of a bus bar (), a terminal (), and an electric wire () connected to the terminal () are arranged; a linkage part () linking the first-group accommodation part () and the second-group accommodation part () to each other; and an electric wire routing part () provided in the linkage part () and accommodating the electric wires ().

Electric wire routing structure for bus bar module

A voltage detecting terminal includes a flat plate-shaped electric contact portion having an insertion hole into which an electrode column of a battery is inserted, and a bent portion formed such that a tip is bent upward with respect to the electric contact portion. The bent portion is provided with a holding portion, and both ends of the holding portion in a plate width direction are expanded in the plate width direction, respectively. The voltage detecting terminal has a lower end surface of the holding portion in a thickness direction abutting against supporting surfaces of the plate and is held by a first housing portion.

Structure for holding voltage detecting terminal

A terminal fixation structure includes a terminal fixing portion including a terminal housing chamber, a terminal including a positioning recessed portion and housed in the terminal housing chamber, and a positioning rib provided in a center of the terminal fixing portion to protrude into the terminal housing chamber and fitted into the positioning recessed portion.

A drawing sectionfor electric wiresis formed such that a bottom plateand a side wallof a wiring pathare extended to be projected from an insulating plate. A tongue piecearound which a tape is wound together with the wires, is formed on the drawing section. The tongue pieceis bent in a direction opposite to a rising direction of the side wallof the drawing sectionso that a projection dimension of the tongue pieceis reduced.

Bus bar module

Abnormal noise at a battery pack busbar module is prevented. A battery pack busbar module includes busbar accommodating portions each accommodate busbars which connect in series batteries, cover portions coupled by hinges to one of side edges of openings in the busbar accommodating portions to cover the openings, and lock portions to lock the cover portions by bringing first engagement portions provided on the other side edges of the busbar accommodating portions and second engagement portions provided on the cover portions into engagement with each other, and ribs projecting from the cover portions to come into abutment with the busbar accommodating portions are formed in positions spaced away from the lock portions, a height of the ribs being set such that the second engagement portions are not brought into engagement with the first engagement portions when the ribs abut the busbar accommodating portions.

Battery pack busbar module

Attaching work of a high-voltage cable is improved. In an electric cable connecting construction of battery packs, the high-voltage cable is connected to conductors held in resin busbar modules for connection with the general electrodes by fastening crimp terminals to the conductors. Two ribs are formed on each of the busbar modules where the crimp terminal is held therebetween to limit an entrained rotation of the crimp terminal. A difference between a gap of the two ribs on one of the adjacent battery packs and a width of the crimp terminal connected to the general electrode is set to a first gap dimension Land A difference between a gap and a width of the crimp terminal connected to the general electrode of the other of the adjacent battery packs is set to a second gap dimension Llarger than the first gap dimension.
