Provided is a wiring module with which there is no risk that a connector will interfere with other components in a state in which the connector is not connected to an external device. A wiring module to be attached to a power storage element group in which a plurality of power storage elements are lined up includes a bus bar for electrically connecting the plurality of power storage elements together, an insulating protector that accommodates the bus bar and is to be mounted onto the power storage element group, a wire that extends from the bus bar to the outside of the insulating protector, a connector that is provided at an extending end portion of the wire, the extending end portion extending from the insulating protector, and a connector holder that is provided in the insulating protector and detachably holds the connector.

Wiring module

A connection apparatus for connecting a battery module and an electronic device is for connecting a battery module in which a plurality of electric cells are arranged in a line and are connected to each other, and an electronic device arranged on a side of the battery module. The connection apparatus includes: a connection bus bar in which a welding plate to be connected to a connection electrode in the battery module is provided at one end, and the other end portion to be connected to a connecting portion of the electronic device is provided at the other end; and an insulating cover that is made of a synthetic resin and is attached to a lower face of the connection bus bar.

Connection apparatus for connecting battery module and electronic device, and method for manufacturing insulating cover

A wiring module comprising: a bus bar that connects adjacent electrode terminals of a plurality of single batteries each having positive and negative electrode terminals; and a detection terminal that is overlaid on the bus bar and is for detecting a state of a single battery among the plurality of single batteries. The detection terminal is provided with a welded portion welded onto the bus bar, a locked portion that locks to a locking portion provided on the bus bar and holds the detection terminal in a state in which the welded portion is overlaid on the bus bar, and a reinforcing portion that prevents the welded portion from performing a bending deformation so as to keep the welded portion in a flat plate shape overlaid on the bus bar.

Wiring module, detection terminal, and method for manufacturing detection terminal

A busbar module () includes a busbar () having a plate-like body () electrically connectable to battery cells (), a barrel () composed of a cut-and-raised portion () formed on the plate-like body () and a wire () fixed to the barrel (). Integration of the plate-like body () to be connected to the battery cells () and the barrel () to be fixed to the wire () achieves a weight reduction.

Busbar module and busbar

In a connection module attached to a single battery group from a first direction, a detection terminal connected to an electrode terminal of the single battery group includes: a body portion made of a metal plate material formed in an approximately rectangular plate shape; and a projection portion in a plate shape connected to a base edge of the body portion and having a plate surface intersecting with a plate surface of the body portion. An insulation protector of the connection module includes a holding portion holding the detection terminal in a posture in which the plate surface of the body portion is orthogonal to the first direction. The holding portion includes a locking piece. A lower surface of a claw portion provided at the lower end of the locking piece locks the plate surface of the body portion and restricts the movement of the detection terminal in the first direction.

Connection module for a power storage group of plural power storage elements

A connection structure () is provided for connecting electrical storage element groups (), each of which is formed by connecting electrical storage elements () having electrode terminals () in series, side by side. The electrical storage element groups () are connected electrically by connecting a connecting member () for connecting adjacent electrical storage element groups () to a first electrode terminal (A) and a second electrode terminal (B). The first electrode terminal (A) is arranged on one end part of one electrical storage element group () and on the side of the adjacent other electrical storage element group () and the second electrode terminal (B) is the electrode terminal () arranged on another end part of the other electrical storage element group (B) opposite to the one end part of the one electrical storage element group (A) and on the side of the adjacent one electrical storage element group (A).

Connection structure for electrical storage element groups

A bus bar that requires less installation space, and can reliably position and hold an electric wire. An electrical wire is to be connected to a bus bar, and the bus bar is to be joined to an electrode terminal of an electricity storage element. The bus bar includes: an electrical wire connection portion that is constituted by a member included in the bus bar, is provided in an end portion of the bus bar, and to which an end portion of the electrical wire is to be connected. The electrical wire connection portion includes a core wire connection portion to which a core wire of the electrical wire is to be connected; and a positioning and holding portion that is configured to position the electrical wire in a direction (a direction indicated by an arrow Z) that is orthogonal to an axial direction of the electrical wire in plan view, and to hold the electrical wire.

Bus bar and connection module provided with the bus bar

An insulating protector of a wiring module is provided with: a first unit that includes a first holding portion that holds one end side, in a connection direction, of the connection members; and a second unit that includes a second holding portion that holds the other end side, in the connection direction, of the connection members. The second holding portion is contiguous with the first holding portion. The first and second holding portions include separating walls that face side edges of the connection members, and coupling portions that couple the first and the second holding portions to each other. The separating walls include enlarged gap portions that are formed so that gaps between the enlarged gap portions and the side edges of the connection members are larger on the side where the coupling portions are located than on the side where ends of the connection members are located.
