A power distribution box includes a bottom cover having a lower surface. Disposed on the lower surface are a pair of axially offset feet. Each of the pair of feet has a first portion and a second portion spaced apart from the lower surface of the bottom cover so as to form an opening having a back wall. The second contact surface is spaced further apart from the lower surface relative to the first contact surface by a ramp portion so as to define the opening to be tapered. The opening is configured to receive a front edge of a bracket. Also disposed on the lower surface is a guide having a first portion that is angled relative to an insertion direction of the power distribution box to a bracket and a linear wall portion configured to slidably engage a side edge of the bracket.

A tolerance absorbing structure of a first power supply distribution box includes a connection terminal to which one end part of a flat distribution member is connected and fixed; a storage case including a connection opening member into which the connection terminal is inserted and fixed to a vehicle body; an elastic support member configured to support the connection terminal freely movably in a three-dimensional direction with respect to the connection opening member; and a flexible conductor configured to connect a substrate connection part of a circuit conductor stored in the storage case and the connection terminal with an extra length.

An electrical connection box includes: a frame main body; a lid assembled to the frame main body; a plate-shaped member sandwiched between the frame main body and the lid; and a bus bar which has a main body arranged on a surface of the plate-shaped member and a terminal portion bent from the main body toward the lid. The bus bar has a protrusion protruding from a side surface of the terminal portion. The lid has a bus bar holding portion into which the terminal portion is inserted. In the bus bar holding portion, a wall portion opposing the side surface of the terminal portion has a holding groove into which the protrusion is press-fitted.

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.

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.

A receptacle terminal includes a main box and a transverse box. The main box has a front, a rear, sides and ends extending between the front and the rear. The main box has a main blade slot open at the rear configured to receive a first blade terminal along a main plane. The main box has a deflectable spring contact configured to engage the first blade terminal when received in the main blade slot. The transverse box has a front, a rear, sides and ends extending between the front and the rear. The transverse box has a transverse blade slot open at the front configured to receive a second blade terminal along a transverse plane. The transverse box is oriented relative to the main box such that the transverse plane is perpendicular to the main plane.

An electrical connection box includes a lower cover, an upper cover, a connector front opening, bus bars, four first ribs formed of two pairs opposing each other with the bus bar, formed on the lower cover, interposed therebetween, and four second ribs formed of two pairs opposing each other with the bus bar, formed on the upper cover, interposed therebetween. The first ribs and the second ribs are provided such that a pair of ribs is provided to oppose each other on one side and on another side with the bus bar interposed therebetween in a vertical direction, and a pair of ribs is provided to oppose each other on one side and on another side with the bus bar interposed therebetween in a width direction. When viewed from a direction of assembling, the first ribs and the second ribs are provided at different positions.

A receptacle terminal includes a box having a front, a rear, first and second sides and first and second ends defining a cavity. A front blade slot is open at the front configured to receive a first blade terminal. A rear blade slot is open at the rear configured to receive a second blade terminal. A spring contact is in the cavity between the front blade slot and the rear blade slot and includes a first mating interface configured to engage the first blade terminal when received in the front blade slot and a second mating interface configured to engage the second blade terminal when received in the rear blade slot. The first end is split including a first flap and a second flap facing each other at a seam. The first flap and the second flap are independently movable relative to each other.
