Description

This invention relates to a conductive member for connecting two electrical components, and a mounting structure for the conductive member. In recent years, efforts toward realizing a low-carbon or decarbonized society have become more active, and research and development on electrification technologies are being conducted in the vehicle sector to reduce CO2 emissions and improve energy efficiency. Patent Document 1 describes an electrical junction box mounted in a vehicle, which houses a fuse, an electrical component, in an electrical component storage compartment. The busbar connected to the terminals of the electrical junction box has a stepped portion, and a structure (finger-prevention structure) is described that narrows the gap between the busbar and the protective cover covering the terminal to prevent fingers from entering the electrical component storage compartment.

Hereinafter, an embodiment of the conductive member and mounting structure for the conductive member of the present invention will be described based on the attached drawings. The drawings should be viewed in the direction of the reference numerals. First, with reference to Figures 1 and 2, the conductive member 40 of one embodiment of the present invention will be described. Figure 1 is a perspective view of the conductive member 40. Figure 2 is a front view of the conductive member 40. In the explanation of Figures 1 and 2, the arrows shown in the figures will be described as the X-axis, Y-axis, and Z-axis directions, respectively. The conductive member 40 comprises a flat conductive portion 41 and an insulating protective cover 50 that covers the outer circumferential surface of the conductive portion 41, and connects two electrical components. The two electrical components can be any components having terminals to which the conductive member 40 is connected; in one example described later, these are two battery modules 11. Here, the conductive member 40 is arranged such that its length is in the X-axis direction and its thickness is in the Y-axis direction. The conductive portion 41 is a busbar formed from a conductive metal material. The conductive portion 41 is formed, for example, by press-forming sheet metal of copper, iron, or aluminum. Alternatively, the conductive portion 41 may be formed by press-forming sheet metal of an alloy such as a copper alloy or an aluminum alloy. The conductive portion 41 has a main body portion 42 covered by a protective cover 50, and a first connection portion 43a and a second connection portion 43b that are exposed from the protective cover 50 and electrically connected to the terminal portions of each electrical component. Note that the main body portion 42 is covered by the protective cover 50 and therefore not visible, so it is shown with a dashed line in the illustration. The first connecting portion 43a is provided at the +X side end 42a of the main body portion 42. The first connecting portion 43a is bent toward the +Y side relative to the main body portion 42. More specifically, the first connecting portion 43a is bent approximately perpendicularly toward the +Y side from the -Z side edge 42e1 of the main body portion 42. Here, the bent portion between the first connecting portion 43a and the main body portion 42 is also referred to as the bent portion 44a. The bent portion 44a is provided on the -Z side relative to the main body portion 42. The second connecting portion 43b is provided at the -X side end 42b of the main body portion 42. The second connecting portion 43b is bent toward the +Y side relative to the main body portion 42. More specifically, the second connecting portion 43b is bent approximately at a right angle toward the +Y side from the +Z side edge 42e2 of the main body portion 42. Here, the bent portion between the second connecting portion 43b and the main body portion 42 is also called the bent portion 44b. The bent portion 44b is provided on the +Z side relative to the main body portion 42. Both the first connecting portion 43a and the second connecting portion 43b have surfaces facing the Z-axis direction and are provided with through holes 45 that penetrate in the Z-axis direction.
