[0054] (Second Embodiment) Next, a second embodiment will be described. Figure 10 is a block diagram of a wire harness structure incorporating the block and crimp connector of this embodiment. In this figure, parts equivalent to those described in Figures 1 to 9 in the first embodiment described above are denoted by the same reference numerals, and their detailed descriptions are omitted.

[0055] As shown in the figure, the wire harness structure 30 includes R / B4, a plurality of electric wires L4 (third electric wires) drawn out from R / B4, a crimp connector 31 provided at the end of R / B4 of the electric wire L4, a box 32 into which the crimp connector 31 is fitted, an electric wire L5 (fourth electric wire) connected between the box 32 and electronic equipment (not shown), and a connector 33 provided at one end of the electric wire L5 and fitted into the box 32.

[0056] Since R / B4 is equivalent to that in the first embodiment described above, a detailed explanation is omitted here. In the first embodiment, R / B4 was connected to BFT3 which was directly attached to battery 2, but in the second embodiment, it is connected to junction box (J / B) 40 instead of BFT3. J / B40, like BFT3, branches off power from battery 2.

[0057] Multiple wires L4 are connected between R / B4 and electronic equipment (not shown). In this embodiment, wire L4 is composed of the wires L1 and L3 described above. The crimp connector 31 is provided at the end of wire L4 away from R / B4.

[0058] As shown in Figures 13 and 14, the crimp connector 31 comprises a connector housing 31A and a crimp terminal 31B housed in the connector housing 31A. The connector housing 31A is provided in a substantially cylindrical shape with openings 31C and 31D on both sides in the direction of the cylinder length. For simplicity of explanation, in Figures 13 and 14, the direction of the cylinder length will be described as the front-rear direction. The electric wire L4 is pulled out from the rear opening 31D of the connector housing 31A. The connector housing 31A has a first housing section 311A ​​and a second housing section 312A that are divided in the vertical direction.

[0059] As shown in Figure 14, the first housing portion 311A ​​is provided with a front opening 313A which forms part of the front opening 31C of the connector housing 31A, a rear opening 314A which forms part of the rear opening 31D of the connector housing 31A, and a lower opening 315A which is provided on the lower side surface that is vertically opposite to the first housing portion 311A.

[0060] The second housing portion 312A, like the first housing portion 311A, is provided with a front opening 316A that forms part of the front opening 31C, a rear opening 317A that forms part of the rear opening 31D, and an upper opening 318A provided on the upper side surface that is vertically opposite to the first housing portion 311A.

[0061] The crimp terminal 31B has a connection portion 311B, a base plate 312B, and a crimp portion 313B. The connection portion 311B is connected to a busbar, which is a connection circuit housed in a box 32, described later. The base plate 312B extends from the connection portion 311B to the rear in the front-to-back direction (the longitudinal direction of the electric wire L4). The base plate 312B is perpendicular to the vertical direction. The crimp portion 313B has a pair of crimp blades 314B, 314B erected below the base plate 312B. The pair of crimp blades 314B, 314B are arranged side by side with a gap in the left-to-right direction. In this embodiment, three crimp portions 313B are arranged side by side in the front-to-back direction on the base plate 312B.

[0062] The wire L4 is inserted between the pair of crimping blades 314B, 314B. The insulation of the wire L4 is cut by the pair of crimping blades 314B, 314B. As a result, the core wire of the wire L4 is pressed between the pair of crimping blades 314B, 314B, and the wire L4 is connected to the crimping terminal 31B.

[0063] The crimp terminals 31B are arranged in a row within the first housing section 311A ​​and the second housing section 312A, with the connecting portion 311B facing the front openings 313A and 316A, the crimp portion 313B facing the rear openings 314A and 317A, and a pair of crimp blades 314B, 314B erected from the bottom plate 312B toward the lower opening 315A and the upper opening 318A. The crimp terminals 31B are arranged in a row within the first housing section 311A ​​and the second housing section 312A, arranged in a left-right direction.

[0064] <Manufacturing method for press-fit connector 31> The crimp terminal 31B is inserted through the lower opening 315A and upper opening 318A of the first housing section 311A ​​and the second housing section 312A, respectively, to house the crimp terminal 31B inside the first housing section 311A ​​and the second housing section 312A. This operation may be performed manually or using a robotic arm.

[0065] Next, the first housing section 311A ​​and the second housing section 312A are transported to the automatic crimping mechanism. The automatic crimping mechanism holds multiple electric wires L4 together. The automatic crimping mechanism inserts the held electric wires L4 into the first housing section 311A ​​and the second housing section 312A through the lower opening 315A and the upper opening 318A, and presses them toward the pair of crimping blades 314B, 314B to perform crimping.

[0066] Next, the lower opening 315A of the first housing portion 311A ​​and the upper opening 318A of the second housing portion 312A are joined together to complete the crimp connector 31.

[0067] As shown in Figures 10 and 11, the box 32 is fitted with the aforementioned crimp connector 31 and the connector 33 attached to the electric wire L5. Multiple boxes 32 are provided and arranged in various parts of the vehicle. In this embodiment, for example, the boxes 32 are provided inside the passenger compartment and in the left and right areas of the engine compartment, which is outside the passenger compartment. A busbar (not shown), which is a connection circuit, is provided inside the box 32, and when the crimp connector 31 and connector 33 are fitted together, the electric wire L4 and the electric wire L5 are connected.

[0068] The wire L5 is connected between the box 32 and the electronic equipment in the area surrounding the box 32. The wire L5 described above can be manufactured using a general-purpose automatic terminal insertion machine.

[0069] According to the wire harness structure 30 with the configuration described above, the R / B4 and wire 4 connected using an automatic crimping machine are dispensed and assembled into the vehicle, and the crimp connector 31 attached to the wire 4 is fitted into the box 32. In addition, the wire L5 is connected between the box 32 and the electronic equipment. This allows the entire assembly from R / B4 to just before the box 32 to be manufactured using an automatic crimping machine, thereby improving productivity and reducing labor costs.

[0070] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. Furthermore, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention.

[0071] The relay block 6C had a crimp connector 19C, but it is not limited to this. As with the fuse block 6A, the crimp connector 19C may be eliminated, and the block housing 20B may be divided into two parts, each housing crimp terminals 14C and 25C.

[0072] In the second embodiment described above, the busbar constituted the connection circuit, but this is not the only possible configuration. For example, the connection portion 311B constituting the crimp connector 31 may be made from a splice terminal, and multiple wires L5 may be directly connected to the splice terminal.

[0073] In the second embodiment described above, the box 32 simply connected the wires L4 and L5, but it is not limited to this. As with R / B4, the box 32 may be provided to allow connection of electronic components such as fuses and FLs, and the wires L4 and L5 may be connected via these electronic components.
