Embodiments for Carrying Out the Invention

[0014] Specific embodiments of the present invention will be described below with reference to the respective figures. Hereinafter, in a state where a wire harness is routed in a vehicle along a predetermined path, an example will be described in which a fuse or a fusible link is added to a power supply wire or a power supply block included in the wire harness to add a location where power can be supplied.

[0015] (Prior Invention) Prior to the invention of the power connection structure according to the embodiment, the present inventors examined the power connection structure shown in Figure 7. Figure 7 is a perspective view of a power connection structure according to a prior invention. For the sake of convenience of explanation of this prior invention, as shown in Figure 7, "front-back direction", "left-right direction", and "up-down direction" are defined. The "front-back direction", "left-right direction", and "up-down direction" are orthogonal to each other.

[0016] The power connection structure shown in Figure 7 includes a male connector 101 and a fuse block 102.

[0017] The male connector 101 has a substantially rectangular parallelepiped shape, with a power line W1 and a ground line W2 incorporated into the housing at the bottom, and two terminal accommodation chambers arranged side by side in the left - right direction and provided in three rows in the front - rear direction at the top.

[0018] The power line W1 and the ground line W2 arranged along the front - rear direction each have a round terminal crimped to one end and a distribution bus bar terminal crimped to the other end, and the distribution bus bar terminals are accommodated in the housing of the male connector 101.

[0019] For the power line W1, the round terminal is connected to the power supply of the relay box, and one end of each of the wire - with - terminals (hereinafter simply referred to as wires) W11, W12, and W13 is connected to the distribution bus bar terminal in each of the left - hand terminal accommodation chambers. The other ends of the wires W11 and W12 are respectively connected to a plurality of loads (+ side) such as electrical components mounted on the vehicle. A tuning - fork bus bar terminal is crimped to the other end of the wire W13, and this tuning - fork bus bar terminal is accommodated in the housing of the fuse block 102.

[0020] For the ground line W2, the round terminal is connected to the body ground (vehicle body metal), and one end of each of the wire - with - terminals W21, W22, and W23 is connected to the distribution bus bar terminal in each of the right - hand terminal accommodation chambers. The other ends of the wires W21, W22, and W23 are respectively connected to a plurality of loads (- side).

[0021] The fuse block 102 houses a plurality of fuses F in the housing. Each fuse F cuts off the circuit between the tuning - fork bus bar terminal and each wire W3 when the current flowing between the tuning - fork bus bar terminal and each wire - with - terminal W3 exceeds the rated value. Each wire W3 is respectively connected to each load (+ side).

[0022] According to the power supply connection structure shown in Fig. 7, power can be supplied from the relay box to each load connected to the wire - with - terminals W3 via the power line W1, the male connector 101, and the fuse block 102. Therefore, in the wire harness mounted on the vehicle, additional locations where power can be supplied to the load via a fuse can be added.

[0023] However, the power supply connection structure shown in FIG. 7 uses the male connector 101, the fuse block 102, and the electric wire W13 that connects the male connector 101 and the fuse block 102, so the number of components is large and there is room for improvement. Hereinafter, the improved power supply connection structure will be described.

[0024] (First Embodiment) FIG. 1 is a perspective view of a power supply connection structure according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view of the block structure BA shown in FIG. 1. In the present embodiment, for convenience of explanation, as shown in FIG. 1, the "front-rear direction", the "left-right direction", and the "up-down direction" are defined. The "front-rear direction", the "left-right direction", and the "up-down direction" are orthogonal to each other.

[0025] The power supply connection structure shown in FIG. 1 includes power supply wires WB1 and WB2 such as battery wires and alternator wires, and a block structure BA.

[0026] The power supply wires WB1 and WB2 that have been pre-divided are overlapped with flat plate portions T1A and T2A having a substantially circular shape at terminals T1 and T2 provided at each end, and are fastened by bolts B (fastening members) inserted through through-holes provided in the flat plate portions T1A and T2A. Each of the power supply wires WB1 and WB2 has one or a plurality of conductors covered with an insulator, but in FIG. 1, the conductors of the power supply wires WB1 and WB2 are not shown.

[0027] The block structure BA has a block body 10, two fuses 21, a fusible link 22, and a bus bar 23. FIG. 1 is a perspective view seen through the block body 10.

[0028] The block body 10 has a substantially rectangular parallelepiped shape, and has, above, two fuse accommodation chambers 11 for accommodating two fuses 21 respectively, and a fusible link accommodation chamber 12 for accommodating a fusible link 22. Two fuses 21 and a fusible link 22 are inserted into the two fuse accommodation chambers 11 and the fusible link accommodation chamber 12 respectively from above. The block body 10 has, below, a bus bar accommodation chamber for accommodating a bus bar 23, and the bus bar 23 is inserted into the bus bar accommodation chamber from below.

[0029] The block body 10 has a first surface 13 and a second surface 14 facing each other. An opening 15 for protruding the fastening portion 233 of the bus bar 23 to the outside is provided on the first surface 13 which is the right side surface, and a fixing fastening portion 16 for fastening and fixing the block body 10 to a mounted body such as a vehicle body is provided on the second surface 14 which is the left side surface. The fixing fastening portion 16 protrudes to the left from the second surface 14 and has a through hole 16A penetrating in the front-rear direction.

[0030] The bus bar 23 is a flat conductive metal member, and has a substantially rectangular bus bar body 230, two tuning fork terminals 231 and tab terminals 232 protruding upward from the bus bar body 230, and a fastening portion 233 protruding to the right from the bus bar body 230. One terminal of the fuse 21 is inserted and fitted into the tuning fork terminal 231 and electrically connected. The female terminal of the fusible link 22 is electrically connected to the tab terminal 232. The fastening portion 233 has a through hole 233a and protrudes from the block body 10 in a state where the bus bar 23 is accommodated in the bus bar accommodation chamber of the block body 10.

[0031] In this way, the block structure BA is assembled by inserting the fusible link 22 and two fuses 21 into the block body 10 from above and inserting the bus bar 23 from below, and the bus bar 23 is electrically connected to the fusible link 22 and the two fuses 21.

[0032] The block structure BA is arranged on the side (left side) of the split power supply wires WB1 and WB2, and the fastening part 233 of the bus bar 23 protruding from the block body 10 is superimposed on the flat parts T1A and T2A of the terminals T1 and T2. With the fastening part 233 superimposed on the flat parts T2A and T1A in this order from the rear, a bolt B is inserted into the through holes provided in each of the flat parts T1A and T2A and the through hole 233a provided in the fastening part 233. The bolt B and the nut N arranged behind the flat part T2A clamp the flat parts T1A and T2A and the fastening part 233, thereby electrically connecting the terminals T1 and T2 and the bus bar 23. The entire terminals T1 and T2 and the fastening part 233 protruding from the block body 10 are covered with an insulating member. The block structure BA is fastened and fixed by screwing a bolt B inserted through the through hole 16A of the fixing fastening part 16 into a screw hole of an object to be attached (not shown).

[0033] As described above, according to the power supply connection structure of the first embodiment, the power supply wires WB1 and WB2 are pre-split, and the flat parts T1A and T2A of the terminals T1 and T2 are connected by being fastened with the bolt B and the nut N. The fastening part 233 of the bus bar 23 protruding from the block body 10 is clamped and connected to the fastening parts (flat parts T1A and T2A) of the power supply wires WB1 and WB2. Therefore, for the power supply wires, with a small number of parts, it is possible to add fuses or fusible links without changing the shape of the power supply block or the like. Also, in the completed wire harness, fuses or fusible links can be added retroactively at the locations where the wires with terminals are fastened by fastening members.

[0034] Also, according to the power supply connection structure of the first embodiment, the fastening part 233 protrudes on the first surface 13 side of the block body 10, and the bus bar 23 is connected to the power supply wires WB1 and WB2. On the other hand, on the second surface 14 side facing the first surface 13, that is, at a location separated from the location where the fastening operation with the power supply wires WB1 and WB2 is performed, the block body 10 can be fixed to the object to be attached, so the workability is good.

[0035] (Modification of the First Embodiment) FIG. 3 is a perspective view of a power supply connection structure according to a modification of the first embodiment. Hereinafter, the differences between the power supply connection structure shown in FIG. 3 and the power supply connection structures shown in FIGS. 1 and 2 will be described. The power supply connection structure shown in FIG. 3 includes a block body 10-1 instead of the block body 10. The block body 10-1 does not have the fixing fastening portion 16 that the block body 10 had, but has an engaging portion 17.

[0036] The engaging portion 17 is provided above the opening 15 on the first surface 13 of the block body 10-1 and engages with a belt FB (fastening tool) for fixing the block body 10-1 to the power supply electric wires WB1 and WB2. The engaging portion 17 is formed by arranging three L-shaped blocks 17-1, 17-2, and 17-3 in parallel in the front-rear direction when viewed in the front-rear direction. Each of the blocks 17-1, 17-2, and 17-3 has a base portion extending in the left-right direction from the first surface 13 and an extending portion extending in the up-down direction from the end of the base portion. Among the blocks 17-1, 17-2, and 17-3 arranged in parallel, the extending portions of the two blocks 17-1 and 17-3 extend from above to below, and the extending portion of the block 17-2 arranged in the center extends from below to above.

[0037] The block structure BA is arranged on the side (left side) of the split power supply electric wires WB1 and WB2. Then, as described above, the fastening portion 233 of the bus bar 23 is overlapped with the flat plate portions T1A and T2A of the terminals T1 and T2 and fastened, so that the terminals T1 and T2 and the bus bar 23 are electrically connected.

[0038] The block structure BA is fastened and fixed by engaging a belt FB, which is an endless belt passed through the power supply wire WB1, with the engaging portion 17. Specifically, as an example, first, before fastening the terminals T1 and T2 to the fastening portion 233 of the bus bar 23, the belt FB is passed through the power supply wire WB1 from the terminal T1 side. Next, the terminals T1 and T2 are fastened to the fastening portion 233 of the bus bar 23. Then, the belt FB passed through the power supply wire WB1 is passed between the first surface 13 of the block main body 10-1 and the extending portion of the engaging portion 17 (blocks 17-1, 17-2, 17-3) and engaged with the engaging portion 17. By engaging the belt FB with the engaging portion 17 in this way, the block structure BA (block main body 10-1) is fixed to the power supply wire WB1.

[0039] According to the power supply connection structure shown in FIG. 3, on the first surface 13 side of the block main body 10-1, the fastening portion 233 of the bus bar 23 is connected to the power supply wires WB1 and WB2. Also, on the same first surface 13 side, the block main body 10-1 can be fixed to the power supply wire WB1 by engaging the belt FB passed through the power supply wire WB1 with the engaging portion 17. Therefore, fuses and the like can be added with space savings.

[0040] (Second Embodiment) FIG. 4 is a perspective view of a power supply connection structure according to a second embodiment of the present invention, and FIG. 5 is an exploded perspective view of the power supply connection structure shown in FIG. 4. FIG. 6 is an exploded perspective view of the block structure shown in FIG. 4. Note that the fuse 41 is not shown in FIG. 6. In the present embodiment, for convenience of explanation, as shown in FIG. 4, "front-rear direction", "left-right direction", and "up-down direction" are defined. The "front-rear direction", "left-right direction", and "up-down direction" are orthogonal to each other.

[0041] The power supply connection structure shown in FIG. 4 includes a power supply wire WB such as a battery wire and an alternator wire, and a block structure BA2.

[0042] The power supply wire WB has one or a plurality of conductors covered with an insulator and is arranged along the front-rear direction.

[0043] The block structure BA2 has a block body 30, a cover 33, a hinge portion 34, a fuse 41 (see FIG. 5), and a bus bar 42. FIG. 4 is a perspective view seen through the block body 30.

[0044] The block body 30 has a fuse housing portion 31 for housing the fuse 41 and a wire housing portion 32 for housing the power supply wire WB. The fuse housing portion 31 is provided above a substantially rectangular parallelepiped-shaped block, and a terminal housing chamber for housing the wire W with terminals is provided below this block. The wire housing portion 32 has a hollow substantially rectangular parallelepiped shape, one side (lower surface side) is open to form an opening 30A, and the front and rear side surfaces are notched in a U shape.

[0045] A cover 33 for covering the opening 30A is attached to the block body 30 via a hinge portion 34. The hinge portion 34 pivotally connects the cover 33 to the block body 30 between a closed position for closing the opening 30A and an open position for opening the opening 30A. The hinge portion 34 is formed by a thin-walled portion of the block body 30 as an example. The cover 33 has a rectangular parallelepiped-shaped bottom wall 33A and side walls provided vertically from the other three sides excluding the side where the hinge portion 34 is attached to the bottom wall 33A. The side walls located in the front-rear direction are notched in a U shape. In the closed position, the bottom wall 33A of the cover 33 closes the opening 30A. In the closed position, the three side walls are housed inside the wire housing portion 32, and the cover 33 is fitted and fixed inside the opening 30A of the block body 30.

[0046] The bus bar 42 is a conductive metal flat plate and has a pressure contact blade 421 and a tuning fork terminal 422. The crimping blade 421 has a pair of crimping pieces extending in a direction (left - right direction) intersecting the extending direction (front - rear direction) of the power supply wire WB, and the power supply wire WB is press - fitted through the lower opening between the pair of crimping pieces. By the press - fitting, the crimping blade 421 bites through the insulator of the power supply wire WB and contacts the conductor. When the crimping blade 421 is further press - fitted, the conductor enters between the pair of crimping pieces, and the power supply wire WB and the crimping blade 421 are electrically connected. The tuning - fork terminal 422 extends substantially orthogonally to the crimping blade 421 at the right - hand end of the crimping blade 421, and the bus bar 42 has a substantially L - shaped cross - section when viewed in the up - down direction. The tuning - fork terminal 422 extends along the extending direction (front - rear direction) of the power supply wire WB, sandwiches the terminal of the fuse 41 from below, and is electrically connected to the fuse 41. The bus bar 42 is disposed in the wire housing portion 32 and the terminal housing chamber, and is electrically connected to the power supply wire WB via the crimping blade 421.

[0047] The block structure BA2 houses the bus bar 42 from below the block body 30 in a state where the cover 33 is disposed in the open position. That is, the block structure BA2 is formed by assembling the bus bar 42 to the block body 30 such that the crimping blade 421 is housed in the wire housing portion 32 and the tuning - fork terminal 422 is housed in the terminal housing chamber located below the fuse housing chamber.

[0048] Next, as shown in FIG. 5, the power supply wire WB is housed in the wire housing portion 32 through the opening 30A, and the crimping blade 421 and the conductor of the power supply wire WB are electrically connected by crimping. Then, the cover 33 is rotated from the open position to the closed position via the hinge portion 34 to close the opening 30A. On the other hand, the fuse 41 is housed in the fuse housing portion 31 from above, and the wire W with a terminal is housed in the terminal housing chamber from below the fuse housing portion 31, and the terminal of the wire W with a terminal is connected to the terminal of the fuse 41. Note that a fuse link may be assembled instead of the fuse 41, or both the fuse and the fuse link may be assembled.

[0049] As described above, according to the power supply connection structure of the second embodiment, the bus bar 42 that conducts with the fuse 41 is directly and electrically connected to the power supply wire WB via the pressure contact blade 421. Therefore, with a small number of parts, it is possible to add a fuse or a fusible link without changing the shape of the power supply block or the like. In addition, a fuse or the like can be connected to an arbitrary position of the power supply wire (+) of the wire harness. Furthermore, a fuse or the like can be added to the completed wire harness as a retrofit.
