A wiring module that is to be attached to a unit cell group in which a plurality of unit cells that each have positive and negative electrode terminals are arranged, including a plurality of basic units arranged in a direction in which the unit cells are arranged. Each of the plurality of basic units includes: a bus bar configured to electrically connect the electrode terminals of two adjacent unit cells to each other; an electrical wire that is to be electrically connected to the unit cells to detect a state of the unit cell group; a fuse configured to electrically connect the bus bar and the electrical wire to each other, and prevent an overcurrent; and a housing provided with a fuse opening into which the fuse is inserted, and a bus bar opening into which the bus bar is inserted. The fuse opening opens in a direction in which the bus bar extends.

A waterproof construction of a three-phase line part includes a three-phase line part having three bus bar construction bodies, a first terminal block provided on one end side of the three-phase line part, a second terminal block provided on the other end side of the three-phase line part, and a tubular exterior member that covers a middle portion of the three-phase line part. One end of the tubular exterior member is water-tightly fixed to a first housing of the first terminal block, and the other end thereof is water-tightly fixed to a second housing of the second terminal block, in a state that the tubular exterior member covers the three-phase line part.

A holding frame for a plug-type connector is intended to have good heat resistance and a high level of mechanical robustness and, when installed in a metallic plug-type connector housing, enable protective grounding while at the same time being convenient to use, in particular during the replacement of individual modules. To this end, it is proposed to manufacture the holding frame at least partially from spring-elastic sheet metal. For this purpose, the holding frame can have a basic portion and a deformation portion, which are formed from different materials. The basic portion is used for fixing an accommodated module in a plane. The deformation portion can assume an insertion state and a holding state, wherein the insertion state permits insertion of at least one module into the holding frame in a direction transverse to the plane and an accommodated module is fixed in the holding state.

An embodiment is directed to a module-to-module power connector configured to form connections between battery modules installed in a battery housing of an energy storage system. The module-to-module power connector includes electrical interfaces and busbar(s) configured to form one or more electrical connections terminals of adjacent battery modules. The busbar(s) is flexibly configured to permit a defined range of movement of the electrical interfaces during insertion of the respective battery modules into respective battery module compartments. The module-to-module power connector may further be arranged inside in a tunnel space, whereby holes are defined in a battery module mounting area housing the battery modules that open into the tunnel space.

The power distributor for vehicles according to the present disclosure includes at least the following components: an electronic attachment and a central distributor module with a printed circuit board for electrical components, a feed-in busbar to connect the printed circuit board to a feed-in terminal, and a cable directly connected to the power distributor. The electronic attachment accommodates the ESD-sensitive electronic components and serves to switch and where applicable to diagnose the electrical components on the printed circuit board and can be connected to the printed circuit board by a plug-in contact with several terminals. According to the present disclosure, the advantages of the printed circuit board for unbundling the signals to the various electrical components are combined with the advantages of a separate electronic attachment.

A connector comprises a first receiving portion formed with a first opening, a second receiving portion formed with a second opening, a first contact portion located inside the first receiving portion and a second contact portion located inside the second receiving portion.
