[0003] [Patent Document 1] JP 2008-41330 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a flexible bus bar as described in JP 2008-41330 A, melting damage occurs when heat input to the flexible bus bar exceeds the allowable temperature of the connection portion between the braided wire and the connection terminal or the insulating coating.

[0005] An object of the present disclosure is to provide a flexible bus bar that can suppress the occurrence of melting damage. [Means for solving the problem]

[0006] A flexible busbar according to one aspect of the present disclosure comprises a flexible conductor having flexibility and conductivity, a first terminal connected to one end of the flexible conductor, a second terminal connected to the other end of the flexible conductor, and an insulating member having insulating properties and covering the flexible conductor, wherein the first terminal and the second terminal have connection ends connected to a connection destination, and an intermediate portion bent relative to the connection ends and provided between the connection ends and the flexible conductor.

[0007] It is also preferable that the insulating member cover a connection portion between the flexible conductor and the first terminal, and a connection portion between the flexible conductor and the second terminal.

[0008] It is also preferable that the intermediate portion of the first terminal has a connecting portion connecting the connection end and the flexible conductor, and a pair of protrusions protruding from the connecting portion in a second direction intersecting a first direction connecting the connection end and the flexible conductor, and formed at positions spaced apart from each other in the first direction. Effect of the Invention

[0009] According to the present disclosure, a flexible bus bar capable of suppressing the occurrence of melting damage is provided. [Brief description of the drawings]

[0010] [Figure 1] FIG. 2 is a perspective view illustrating a state in which a flexible bus bar according to an embodiment of the present disclosure is connected; [Diagram 2] FIG. [Diagram 3] FIG. 13 is a perspective view showing a modified example of the flexible bus bar. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present disclosure will now be described with reference to the accompanying drawings, in which the same or corresponding components are designated by the same reference numerals.

[0012] Fig. 1 is a perspective view showing a schematic state in which a flexible bus bar according to an embodiment of the present disclosure is connected. The flexible bus bar 1 is used, for example, in a vehicle. As shown in Fig. 1, the flexible bus bar 1 is connected to a terminal block 10 of the vehicle and a stator terminal 22 provided on a stator 20.

[0013] As shown in Fig. 2, the flexible busbar 1 includes a flexible conductor 100, a first terminal 200, a second terminal 300, and an insulating member 400. Note that in Fig. 1, the insulating member 400 is omitted, and the flexible conductor 100 is shown diagrammatically.

[0014] The flexible conductor 100 has flexibility and conductivity. The flexible conductor 100 is made of a conductor capable of carrying a large current. The flexible conductor 100 is made of, for example, a collection of conducting wires, a braided wire, or a bundle of electric wires. The flexible conductor 100 can absorb assembly variations (such as component dimensions and water marks during fastening).

[0015] The first terminal 200 is connected to one end 101 of the flexible conductor 100. The first terminal 200 is connected to the flexible conductor 100 by welding, melting, or crimping. The first terminal 200 is made of a single metal plate. The first terminal 200 has a connection end 210 and an intermediate portion 220.

[0016] The connection end 210 is a portion that is connected to a connection destination (terminal block 10). The connection end 210 is provided with a through hole 210h through which a fastening member such as a bolt is inserted.

[0017] The intermediate portion 220 is bent with respect to the connection end portion 210. The intermediate portion 220 is provided between the connection end portion 210 and the flexible conductor 100. The surface area of ​​the intermediate portion 220 is larger than the surface area of ​​the connection end portion 210. The intermediate portion 220 has a coupling portion 222 and a pair of protrusions 224.

[0018] The coupling portion 222 couples the connection end portion 210 and one end portion 101 of the flexible conductor 100. The coupling portion 222 is formed in a flat plate shape.

[0019] The pair of protrusions 224 protrude from the coupling portion 222 in a second direction (see FIG. 2) intersecting with a first direction (see FIG. 2) connecting the connection end portion 210 and the flexible conductor 100. The pair of protrusions 224 are formed at positions spaced apart from each other in the first direction. The protruding dimension of each protrusion 224 may be smaller than the dimension of the coupling portion 222 in the second direction. The dimension of each protrusion 224 in the first direction may be larger than the distance between the protrusions 224 in the first direction.

[0020] The second terminal 300 is connected to the other end 102 of the flexible conductor 100. The second terminal 300 is connected to the flexible conductor 100 by welding, melting, or crimping. The second terminal 300 is made of a single metal plate. The second terminal 300 has a connection end 310 and an intermediate portion 320.

[0021] The connection end 310 is a portion that is connected to a connection destination (the stator terminal 22). In this embodiment, the connection end 310 is configured as a terminal with a nut. The connection end 310 is connected to the stator terminal 22 by a fastening member 30 (see FIG. 1) such as a bolt.

[0022] The intermediate portion 320 is bent with respect to the connection end portion 310. The intermediate portion 320 is provided between the connection end portion 310 and the flexible conductor 100. The surface area of ​​the intermediate portion 320 is larger than the surface area of ​​the connection end portion 310.

[0023] The insulating member 400 has insulating properties and covers the flexible conductor 100. The insulating member 400 covers the connection portion between the flexible conductor 100 and the first terminal 200, and the connection portion between the flexible conductor 100 and the second terminal 300. The insulating member 400 is made of, for example, a resin film or tube.

[0024] As described above, the flexible busbar 1 of the present embodiment has the intermediate portions 220, 320 bent relative to the connection ends 210, 310, thereby ensuring the surface area of ​​the first terminal 200 and the second terminal 300. This improves the heat dissipation of the terminals 200, 300, thereby suppressing the occurrence of melting damage.

[0025] Furthermore, since the intermediate portion 220 of the first terminal 200 has a pair of protrusions 224, the surface area of ​​the first terminal 200 is further ensured. Furthermore, since the pair of protrusions 224 can hold the components during assembly, the assembly performance is improved.

[0026] It should be noted that the embodiments disclosed herein are illustrative in all respects and should not be considered as limiting. The scope of the present invention is indicated by the claims, not by the description of the embodiments above, and further includes all modifications within the meaning and scope of the claims.

[0027] 3, the intermediate portion 220 of the first terminal 200 may further have a pair of other protrusions 226. The other protrusions 226 are disposed on the opposite side to the protrusion 224 with respect to the connecting portion 222 in the second direction. [Explanation of symbols]
