[0011] (Reference example) Before describing specific embodiments of the present invention, a reference example will be described with reference to Fig. 13. A distribution device 100 shown in the reference example is a device that distributes power supplied from a trunk line L1 to multiple branch lines L2 (three branch lines in this embodiment). Terminal fittings T1 and T2, which are LA terminals provided with screw insertion holes for screws Sc, are attached to the ends of the trunk line L1 and the multiple branch lines L2. The distribution device 100 includes a fuse H10, a bus bar 101, and a resin block 102 to which a nut is fixed. One end of the fuse H10 and the terminal fitting T1 of the trunk line L1 are fastened together and attached to the resin block 102 by the screw Sc and the nut.

[0012] The bus bar 101 is provided with a screw insertion hole for connecting the fuse H10 and three screw insertion holes for connecting the terminal fitting T2 of the branch line L2. The other end of the fuse H10 and the bus bar 101 are fastened together with a screw Sc and a nut N and attached to the resin block 102. The terminal fitting T2 of the branch line L2 and the bus bar 101 are also fastened together with a screw Sc and a nut N and attached to the resin block 102. This allows power from the trunk line L1 to be distributed to the branch line L2.

[0013] However, in the above-described reference example, if it was desired to add more branch lines L2, it was necessary to increase the size of the resin block 102 itself and connect more branch lines L2. In other words, if it was desired to add more branch lines L2, it was necessary to replace the distribution device 100 itself, and it was not easy to add more branch lines L2.

[0014] Next, specific embodiments of the present invention will be described below with reference to the drawings. For convenience of explanation, the following terms are defined as "front-rear direction," "left-right direction," "up-down direction," "front," "rear," "left," "right," "up," and "down" as shown in Figure 1 etc. The "front-rear direction," "left-right direction," and "up-down direction" are perpendicular to each other.

[0015] (First embodiment) Next, a distribution device in a first embodiment that solves the above problems will be described with reference to Figures 1 to 4. The distribution device 1A of this embodiment is a device that branches power supplied from one trunk line L1 into four branch lines L2. As shown in Figures 1 and 2, the distribution device 1A includes a first block assembly 2L to which the trunk line L1 and two branch lines L2 are attached, a second block assembly 2R to which the two branch lines L2 are attached, a fuse (third conductive part) H1, and a joint block 3.

[0016] First, the first block assembly 2L will be described. As shown in FIGS. 2 and 3, the first block assembly 2L has a first conductive portion 21L and a first resin block 22L to which the first conductive portion 21L is attached. A terminal fitting T1 to which an end of the trunk line L1 is attached and terminal fittings T2 to which ends of two branch lines L2 are attached are connected to the first conductive portion 21L. In this embodiment, the terminal fittings T1 and T2 are configured as LA terminals provided with circular screw insertion holes HS into which screws Sc are inserted.

[0017] Next, the first conductive portion 21L will be described. In this embodiment, the first conductive portion 21L is composed of a first bus bar 23L and two fuses H21 and H22. The first bus bar 23L is a wiring member obtained by pressing a metal plate or the like. As shown in FIG. 3 and other figures, the first bus bar 23L is composed of an upper plate portion 231L that is vertically aligned in the up-down direction, a side plate portion 232L that is vertically aligned in the left-right direction and hangs downward from the front end at the left end of the upper plate portion 231L, a lower plate portion 233L that is vertically aligned in the up-down direction and extends rightward from the lower end of the side plate portion 232L, and a locking plate portion 234L that is vertically aligned in the front-rear direction and extends rightward from the rear end of the side plate portion 232L.

[0018] The upper plate portion 231L has three circular screw insertion holes HS arranged in the front-to-rear direction for inserting the screws Sc. The lower plate portion 233L has one circular screw insertion hole HS for inserting the screws Sc. The locking plate portion 234L has a locking hole (not shown) that locks with a locking protrusion (not shown) of the first resin block 22L.

[0019] Fuses H21 and H22 each include a fuse body 24 made of a chip fuse and a pair of connection portions 25 protruding from both front and rear ends of the fuse body 24. When an overcurrent flows through the fuse body 24, the fuse body 24 melts and cuts off the overcurrent. The pair of connection portions 25 are formed in a plate shape and are provided with screw insertion holes HS for passing screws Sc through.

[0020] The first resin block 22L is formed in a cubic shape that is elongated in the front-rear direction. The left-right length of the first resin block 22L is approximately equal to the left-right length of the fuse main body 24. A fuse accommodating portion 221L and two nut fixing portions 222L that position the fuse accommodating portion 221L are arranged side by side in the front-rear direction on the upper and lower surfaces of the first resin block 22L. The fuse accommodating portions 221L on the upper and lower surfaces of the first resin block 22L face each other in the vertical direction. The nut fixing portions 222L on the upper and lower surfaces of the first resin block 22L also face each other in the vertical direction. A nut fixing portion 223L is further provided on the upper surface of the first resin block 22L, rearward of the nut fixing portion 222L.

[0021] A nut N that screws into the screw Sc is fixed to the nut fixing portions 222L, 223L. The nut fixing portions 222L, 223L are recessed from the upper and lower surfaces of the first resin block 22L. A groove is formed on the inner surface of this recess, into which a flange provided on the end of the nut N is inserted. The recess and groove of the nut fixing portions 222L, 223L are extended to the left end of the first resin block 22L, and an opening is provided on the left side. The flange provided on the end of the nut N is inserted from this opening into the groove of the nut fixing portions 222L, 223L and fixed.

[0022] The fuse accommodating portion 221L accommodates the fuse bodies 24 of the fuses H21 and H22. The fuse accommodating portion 221L is recessed from the upper and lower surfaces of the first resin block 22L. The fuse accommodating portion 221L extends to both left and right ends, and has openings on both the left and right sides.

[0023] The first resin block 22L is also provided with two locking holes 224L that penetrate in the left-right direction and are aligned in the front-rear direction. A locking arm 311 provided on the joint block 3 (described later) is inserted through the right opening of the two locking holes 224L, and a locking protrusion 312 provided at the tip of the locking arm 311 locks onto the left side surface of the first resin block 22L. One of the two locking holes 224L is provided between the fuse accommodating portions 221L provided on the upper and lower surfaces of the first resin block 22L. The other is provided forward of the front nut fixing portion 222L.

[0024] Furthermore, a T-shaped locking groove 226L is provided on the rear surface of the first resin block 22L when viewed from the left-right direction. The locking groove 226L extends in the left-right direction and is open on both sides. A T-shaped locking portion 322 provided on the joint block 3 (described later) can be slidably inserted through this opening.

[0025] Next, the second block assembly 2R will be described. The first block assembly 2L and the second block assembly 2R are formed as mirror images symmetrical in the left-right direction. Therefore, the second block assembly 2R can be roughly described in the same way as the first block assembly 2L described above by replacing "first" with "second," "L" with "R," "left" with "right," and "Figure 3" with "Figure 4." Therefore, a detailed description will be omitted here. The difference between the first block assembly 2L and the second block assembly 2R is that the second conductive part 21R is connected only to terminals T2 attached to the ends of the two branch lines L2, and is not connected to the main line L1.

[0026] Next, the joint block 3 will be described. As shown in Fig. 1, the first block assembly 2L and the second block assembly 2R are arranged on both the left and right sides of the joint block 3, and the fuse H1 is arranged on the joint block 3. As shown in Fig. 2, the joint block 3 has a main body portion 31 in which the first block assembly 2L and the second block assembly 2R are positioned on both the left and right sides, and a rear end portion 32 provided on the rear side of the main body portion 31.

[0027] The main body 31 is formed in a cubic shape that is long in the front-rear direction. Two pairs of locking arms 311 protrude from both left and right side surfaces of the main body 31. The locking arms 311 are formed in the shape of plates that are vertical in the up-down direction and are flexible in the up-down direction. The locking arms 311 also extend in the left-right direction and are provided with locking protrusions 312 that protrude upward at their tips. When the locking arms 311 are inserted into the locking holes 224L, 224R, the locking protrusions 312 are locked with the left side surface of the first resin block 22L and the right side surface of the second resin block 22R. This locks the first resin block 22L and the second resin block 22R to the joint block 3 in the left-right direction.

[0028] The main body 31 is also provided lower than the vertical height of the first resin block 22L and the second resin block 22R. As a result, when the first block assembly 2L and the second block assembly 2R are assembled with the joint block 3, the main body 31 is recessed below the first resin block 22L and the second resin block 22R, as shown in Fig. 1, and the fuse main body 24 of the fuse H1 can be accommodated in this recess.

[0029] As shown in FIG. 2, the rear end portion 32 is longer in the left-right direction than the main body portion 31. Specifically, the rear end portion 32 is approximately equal to the sum of the left-right length of the first resin block 22L, the left-right length of the main body portion 31, and the left-right length of the second resin block 22R. The rear end portion 32 is also approximately the same height as the first resin block 22L and the second resin block 22R. The main body portion 31 protrudes from the front end surface of the rear end portion 32. The rear end portion 32 and the lower surface of the main body portion 31 are approximately flush with each other. As a result, the upper surface of the main body portion 31 is positioned lower than the upper surface of the rear end portion 32.

[0030] Further, a nut fixing portion 321 for fixing the nut N is provided on the upper surface of the rear end portion 32. Two nut fixing portions 321 are provided side by side in the left-right direction. The nut fixing portion 321 is recessed from the upper surface, and a groove into which the flange of the nut N is inserted is formed on the inner surface of the recess. Furthermore, the recess and groove of the nut fixing portion 321 are provided extending to the rear end. As a result, an opening is provided on the rear side of the nut fixing portion 321, and the flange of the nut N can be inserted and fixed into the groove of the nut fixing portion 321 from this opening. In this embodiment, the nut is fixed to the nut fixing portion 321 provided on the left side.

[0031] Furthermore, two T-shaped locking portions 322 are provided on the front surface of the rear end portion 32, sandwiching the main body portion 31. The locking portions 322 are formed into a T shape and are composed of a first portion 322A that protrudes forward and extends in the left-right direction, and a second portion 322B that protrudes in the up-down direction from the front end of the first portion 322A and extends in the left-right direction. The T-shaped locking portions 322 are slidably inserted into locking grooves 226L, 226R provided in the first and second resin blocks 22L, 22R, and the first and second resin blocks 22L, 22R and the joint block 3 are locked in the front-rear direction.

[0032] Next, the assembly procedure for the above-described distribution device 1A will be described. First, the first block assembly 2L is assembled. Nuts N are fixed to the nut fixing portions 222L and 223L of the first resin block 22L. Next, the first bus bar 23L is moved from left to right, and a locking protrusion (not shown) provided on the first resin block 22L is inserted into a locking hole provided in the locking plate portion 234L of the first bus bar 23L, thereby locking the first bus bar 23L to the first resin block 22L.

[0033] At this time, the upper plate portion 231L of the first bus bar 23L is disposed on the upper surface of the first resin block 22L, the side plate portion 232L is disposed on the left side surface of the first resin block 22L, and the lower plate portion 233L is disposed on the lower surface of the first resin block 22L. Furthermore, the frontmost screw insertion hole HS provided in the upper plate portion 231L and the screw insertion hole HS provided in the lower plate portion 233L are opposed in the vertical direction to the nut N fixed to the rear side of the nut fixing portion 222L. Furthermore, the middle screw insertion hole HS provided in the upper plate portion 231L is opposed in the vertical direction to the nut N fixed to the nut fixing portion 223L.

[0034] Next, one side of the connection portion 25 of the fuse H21 is placed on the upper plate portion 231L, and one side of the connection portion 25 of the fuse H22 is placed on the lower plate portion 233L. A screw Sc is passed through a screw insertion hole HS provided on one side of the connection portion 25 of the fuse H21 and the front-most screw insertion hole HS of the upper plate portion 231L, and then screwed into a nut N fixed to the rear side of one of the nut fixing portions 222L provided on the upper surface of the first resin block 22L. Also, a screw Sc is passed through a screw insertion hole HS provided on one side of the connection portion 25 of the fuse H22 and the screw insertion hole HS provided on the lower plate portion 233L, and then screwed into a nut N fixed to the rear side of one of the nut fixing portions 222L provided on the lower surface of the first resin block 22L. This causes the first bus bar 23L and the fuses H21 and H22 to be fastened together to the first resin block 22L.

[0035] Furthermore, the terminal fittings T2 are placed on the other side of the connection portions 25 of the fuses H21 and H22. At this time, the terminal fittings T2 are placed so that the branch wire L2 is forward of the terminal fittings T2 and the longitudinal direction of the branch wire L2 is parallel to the front-to-rear direction. Next, a screw Sc is passed through the screw insertion hole HS provided in the terminal fitting T2 and the screw insertion hole HS provided in the other side of the connection portions 25 of the fuses H21 and H22, and is screwed into the nut N fixed to the front side of the nut fixing portions 222L provided on the upper and lower surfaces of the first resin block 22L. This fastens the fuses H21 and H22 and the terminal fitting T2 together to the first resin block 22L. The first block assembly 2L is completed through the above assembly process.

[0036] The second block assembly 2R is assembled in the same manner. The assembly of the second block assembly 2R can be explained by replacing "first" with "second," "L" with "R," and "left" with "right" in the assembly of the first block assembly 2L described above, so a detailed explanation will be omitted here.

[0037] Next, the first block assembly 2L and the second block assembly 2R are assembled to the joint block 3. First, the assembly of the first block assembly 2L will be described. The first block assembly 2L is moved from left to right, approaching the joint block 3. Then, the left side of the two locking portions 332 provided on the joint block 3 is slid and inserted into the locking groove 226L of the first block assembly 2L. In addition, the locking arm 311 of the joint block 3 is inserted from the right opening of the locking hole 224L of the first block assembly 2L. When the first block assembly 2L is further moved from left to right, the locking protrusion 312 provided at the tip of the locking arm 311 engages with the left side surface of the first resin block 22L. This completes the attachment of the first block assembly 2L to the joint block 3.

[0038] The assembly of the second block assembly 2R can be explained by replacing "first" with "second," "L" with "R," and "left" with "right" in the installation of the first block assembly 2L described above, so a detailed explanation will be omitted here.

[0039] Next, the fuse H1 and the trunk line L1 are attached. First, the attachment of the fuse H1 will be described. The connection portion 25 of the fuse H1 is placed on the upper plate portion 231L of the first bus bar 23L and the upper plate portion 231R of the second bus bar 23R, respectively. The screw Sc is passed through the screw insertion hole HS provided in the connection portion 25 of the fuse H1 and the screw insertion hole HS provided in the center of the upper plate portions 231L and 231R, and then screwed into the nut N fixed to the nut fixing portions 223L and 223R. This causes the first bus bar 23L, the second bus bar 23R, and the fuse H1 to be fastened together to the first and second resin blocks 22L and 22R.

[0040] Next, the installation of the trunk line L1 will be described. When the first and second block assemblies 2L and 2R are attached to the joint block 3, the rear ends of the upper plate portions 231L and 231R of the first and second bus bars 23L and 23R are placed on the rear end portion 32. The terminal fitting T1 is then placed on the upper plate portion 231L that is placed on the rear end portion 32. At this time, the terminal fitting T1 is placed so that the trunk line L1 is located rearward of the terminal fitting T1 and the longitudinal direction of the trunk line L1 is parallel to the front-to-rear direction. Next, the screw Sc is threaded through the screw insertion hole HS provided in the terminal fitting T1 and the screw insertion hole HS provided at the rearmost position of the upper plate portion 231L and then screwed into the nut N fixed to the rear end portion 32. This tightens the terminal fitting T1 and the first bus bar 23L together to the joint block 3. The above assembly process completes the distribution device 1A.

[0041] According to the first embodiment described above, the fuse H1 is connected between the first bus bar 23L of the first block assembly 2L and the second bus bar 23R of the second block assembly 2R. As a result, normally, only one of the first block assembly 2L and the second block assembly 2R is used, and when it is desired to add a branch line L2, the branch line L2 can be easily added by connecting the first bus bar 23L of the first block assembly 2L and the second bus bar 23R of the second block assembly 2R with the fuse H1.

[0042] Furthermore, according to the first embodiment described above, the terminal fittings T1, T2 provided at the ends of the main line L1 and the branch lines L2 are connected to the first conductive part 21L and the second conductive part 21R so that the longitudinal directions of the main line L1 and the branch lines L2 are parallel to the front-rear direction. The first block assembly 2L and the second block assembly 2R are arranged side by side in the left-right direction. This allows for miniaturization.

[0043] Furthermore, according to the first embodiment described above, the distribution device 1A includes the joint block 3 disposed between the first resin block 22L and the second resin block 22R, and the fuse H1 is disposed on the joint block 3. As a result, even if there is no mounting space for the fuse H1 on the first resin block 22L and the second resin block 22R, by providing the joint block 3, it is possible to provide a mounting space for the fuse H1 in the joint block 3.

[0044] Furthermore, according to the first embodiment described above, the terminal fittings T2 are arranged on the upper and lower surfaces (outer surfaces) of the first resin block 22L and the second resin block 22R, which face each other in the vertical direction perpendicular to both the front-rear direction (longitudinal direction) and the left-right direction (arrangement direction of the first and second block assemblies 2L, 2R). This allows for size reduction in the left-right direction.

[0045] In the first embodiment described above, the first conductive portion 21L is composed of the first bus bar 23L and two fuses H21 and H22, but this is not limited to this. The first conductive portion 21L may be composed of only the first bus bar 23L, as shown in Fig. 5. In the example shown in Fig. 5, the branch line L2 is not connected to the first bus bar 23L via the fuses H21 and H22, but is connected directly to the first bus bar 23L.

[0046] (Second embodiment) Next, a distribution device 1B according to a second embodiment will be described with reference to Figures 6 to 10. In Figures 6 to 10, parts equivalent to those of the distribution device 1A shown in Figures 1 to 4 described in the first embodiment above will be assigned the same reference numerals, and detailed description thereof will be omitted.

[0047] The distribution device 1B of this embodiment is a device that branches power supplied from two trunk lines L1 into six branch lines L2. One of the two trunk lines L1 (the left side in the figure) is connected to an alternator (not shown) and supplies power from the alternator. The other (the right side in the figure) is connected to a battery (not shown) and supplies power from the battery.

[0048] The distribution device 1B of the first embodiment has a joint block 3 to ensure a space for accommodating the fuse H1, but the distribution device 1B of the second embodiment does not have the joint block 3. As shown in Figure 6 etc., the distribution device 1B of the second embodiment has a first block assembly 2LB, a second block assembly 2RB, and a fuse (third conductive part) H1.

[0049] First, the first block assembly 2LB will be described. As shown in Figures 7, 9, etc., the first block assembly 2LB has a first conductive part 21LB and a first resin block 22LB to which the first conductive part 21LB is attached. A terminal fitting T1 to which one end of the trunk line L1 is attached, and terminal fittings T2 to which the ends of the three branch lines L2 are attached are connected to the first conductive part 21LB.

[0050] First, the first conductive part 21LB will be described. In this embodiment, the first conductive part 21LB is composed of a first bus bar 23LB and two fuses H21 and H22. The first bus bar 23LB is a wiring member obtained by performing a press process or the like on a metal plate. As shown in Figure 9, the first bus bar 23LB is composed of an upper plate portion 231LB that is vertical in the vertical direction, a rear side plate portion 232LB that is vertical in the front-to-rear direction and extends upward from the front end of the upper plate portion 231LB, an upper plate portion 233LB that is vertical in the vertical direction and extends forward from the upper end of the rear side plate portion 232LB, a side plate portion 234LB that is vertical in the left-to-right direction and hangs downward from the left end of the upper plate portion 233LB, a lower plate portion 235LB that is vertical in the vertical direction and extends rightward from the lower end of the side plate portion 234LB, a side plate portion 236LB that protrudes forward from the front end of the side plate portion 234LB and is arranged on the same plane as the side plate portion 234LB, and a locking plate portion 237LB (see Figure 7) that is vertical in the front-to-rear direction and extends rightward from the rear end of the side plate portion 234LB.

[0051] As shown in FIG. 9, the upper plate portion 231LB is provided with a bolt insertion hole HB for inserting a bolt B (described later) and a screw insertion hole HS for inserting a screw Sc, which are aligned in the front-rear direction. The bolt insertion hole HB is located rearward of the screw insertion hole HS and extends to the right end of the upper plate portion 231LB, with an opening on the right side. The bolt B can be inserted into the bolt insertion hole HB through this opening. The upper plate portion 233LB, the side plate portion 236LB, and the lower plate portion 235LB each have one screw insertion hole HS for inserting a screw Sc. The locking plate portion 237LB (FIG. 7) is provided with a locking hole (not shown) that is engaged with a locking protrusion (not shown) of the first resin block 22LB.

[0052] The fuses H21 and H22 are similar to those in the first embodiment, and therefore a detailed description thereof will be omitted here.

[0053] The first resin block 22LB is formed in a cubic shape that is elongated in the front-rear direction. The left-right length of the first resin block 22LB is longer than the left-right length of the fuse body 24. The first resin block 22LB has a rear end portion 221LB, a front end portion 222LB, a plurality of locking arms 224LB (first locking portions), and a plurality of locking portions 225LB (first locking portions). The upper surface of the rear end portion 221LB is located lower than the upper surface of the front end portion 222LB, and a step surface 223LB is provided between the rear end portion 221LB and the front end portion 222LB. A bolt fixing portion 226LB and a nut fixing portion 227LB are provided on the upper surface of the rear end portion 221LB, aligned in the front-rear direction. The bolt fixing portion 226LB is located rearward of the nut fixing portion 227LB. The nut fixing portion 227LB is provided on the left side of the rear end portion 221LB, and an accommodation space for accommodating the left half of the fuse body 24 of the fuse H1 is provided to the right of the nut fixing portion 227LB.

[0054] A fuse accommodating portion 228LB and a nut fixing portion 229LB for positioning the fuse accommodating portion 228LB between them are provided side by side in the front-rear direction on the upper and lower surfaces of the front end portion 222LB, respectively. The fuse accommodating portions 228LB provided on the upper and lower surfaces of the front end portion 222LB face each other in the vertical direction. The nut fixing portions 229LB provided on the upper and lower surfaces of the front end portion 222LB also face each other in the vertical direction. The fuse accommodating portion 228LB and a nut fixing portion 229LB for positioning the fuse accommodating portion 228LB between them are also provided side by side in the front-rear direction on the left side of the front end portion 222LB. The rear nut fixing portion 229LB provided on the left side is positioned vertically aligned with the fuse accommodating portions 228LB provided on the upper and lower surfaces. The fuse accommodating portion 228LB provided on the left side is positioned vertically aligned with the front of the nut fixing portions 229LB provided on the upper and lower surfaces. The front nut fixing portion 229LB provided on the left side surface is located further forward than the front nut fixing portions 229LB provided on the top and bottom surfaces.

[0055] A nut N that screws into the screw Sc is fixed to the nut fixing portions 227LB and 229LB. The nut fixing portions 227LB and 229LB are recessed from the top, left, and bottom surfaces of the first resin block 22LB, and a groove into which a flange provided at the end of the nut N is inserted is formed on the inner surface of the recess. The recess and groove of the nut fixing portion 227LB extend to the left end of the rear end portion 221LB and open to the left. The recess and groove of the nut fixing portion 229LB provided on the top and bottom surfaces of the front end portion 222LB extend to the left end of the front end portion 222LB and open to the left. The recess and groove of the nut fixing portion 229LB provided on the left side of the front end portion 222LB extend to the upper end of the front end portion 222B and open upward. The flange of the nut N is inserted into the groove through the opening of these nut fixing portions 227LB and 229LB and fixed.

[0056] The fuse accommodating portion 228LB accommodates the fuse bodies 24 of the fuses H21 and H22. The fuse accommodating portion 228LB is recessed from the upper and lower surfaces of the first resin block 22LB. The fuse accommodating portion 228LB extends to both left and right ends, and has openings on both the left and right sides.

[0057] The multiple locking arms 224LB and the multiple locking portions 225LB are arranged alternately in the front-rear direction to be locked to a second resin block 22RB (described later). The multiple locking arms 224LB and the multiple locking portions 225LB are provided so as to protrude to the right from the rear end portion 221LB and the front end portion 222LB. The locking arms 224LB are provided so as to be flexible in the front-rear direction, and a locking protrusion that protrudes rearward is provided at the right end. The locking portion 225LB is formed in a plate shape that is perpendicular to the front-rear direction, and a locking protrusion that protrudes rearward is provided on the periphery.

[0058] Next, the second block assembly 2RB will be described. The first block assembly 2LB and the second block assembly 2RB are formed as mirror parts that are approximately symmetrical in the left-right direction. Therefore, in the above description of the first block assembly 2LB, if you replace "first" with "second," "L" with "R," "left" with "right," and "Figure 9" with "Figure 10," the second block assembly 2RB can be roughly described in a similar manner, so a detailed description will be omitted here.

[0059] The first block assembly 2LB differs from the second block assembly 2RB in that the other end of the main line L1 is connected to the second conductive portion 21RL. The first block assembly 2LB and the second block assembly 2RB are not symmetrical with each other in the shape of the top surface of the rear end portion 221RB and the shape of the upper plate portion 231RB. In the second embodiment, a nut fixing portion 227RB is provided on the top surface of the rear end portion 221RB instead of the bolt fixing portion 226LB. Furthermore, a screw insertion hole HS is provided on the upper plate portion 231RB instead of the bolt insertion hole HB.

[0060] Furthermore, the locking arm 224RB (second locking portion) and the locking portion 225RB (second locking portion) are not symmetrical. The locking arm 224RB of the second resin block 22RB is disposed at a position facing the locking portion 225LB of the first resin block 22LB in the left-right direction, and the locking protrusions provided on the locking arm 224RB and the locking portion 225LB lock with each other in the left-right direction. The locking portion 225RB of the second resin block 22RB is disposed at a position facing the locking arm 224RB of the first resin block 22LB in the left-right direction, and the locking protrusions provided on the locking portion 225RB and the locking arm 224RB lock with each other in the left-right direction.

[0061] Next, the assembly procedure for the above-described distribution device 1B will be described. First, the first block assembly 2LB is assembled. Nuts N are fixed to the nut fixing portions 227LB and 229LB of the first resin block 22LB. Also, bolts B are fixed to the bolt fixing portion 226LB of the first resin block 22LB. Next, the first bus bar 23LB is moved from left to right, and the locking protrusion (not shown) provided on the first resin block 22LB is inserted into the locking hole provided in the locking plate portion 237LB of the first bus bar 23LB, thereby locking the first bus bar 23LB to the first resin block 22LB.

[0062] At this time, the upper plate portion 231LB of the first bus bar 23LB is disposed on the upper surface of the rear end portion 221LB, the rear side plate portion 232LB is disposed on the stepped surface 223LB, the upper plate portion 233LB is disposed on the upper surface of the front end portion 222LB, the side plate portions 234LB and 236LB are disposed on the left side surface of the front end portion 222LB, and the lower plate portion 235LB is disposed on the lower surface of the front end portion 222LB. At this time, the shank of the bolt B is inserted into the bolt insertion hole HB provided in the upper plate portion 231LB. Furthermore, the screw insertion hole HS provided in the upper plate portion 231LB faces the nut N fixed to the nut fixing portion 227LB in the vertical direction. Furthermore, the screw insertion hole HS provided in the upper plate portion 233LB, the side plate portion 236LB, and the lower plate portion 235LB face the nut N fixed to the nut fixing portion 229LB in the vertical direction.

[0063] Next, one side of the connection portion 25 of the fuse H21 is placed on the upper plate portion 233LB, and one side of the connection portion 25 of the fuse H22 is placed on the lower plate portion 235LB. A screw Sc is passed through a screw insertion hole HS provided on one side of the connection portion 25 of the fuse H21 and a screw insertion hole HS provided on the upper plate portion 233LB, and then screwed into a nut N fixed to the rear side of a nut fixing portion 229LB provided on the upper surface of the front end portion 222LB. A screw Sc is also passed through a screw insertion hole HS provided on one side of the connection portion 25 of the fuse H22 and a screw insertion hole HS provided on the lower plate portion 235LB, and then screwed into a nut N fixed to the rear side of a nut fixing portion 229LB provided on the lower surface of the front end portion 222LB. This causes the first bus bar 23LB and the fuses H21 and H22 to be fastened together to the first resin block 22LB.

[0064] Furthermore, the terminal fittings T2 are placed on the other side of the connection portions 25 of the fuses H21 and H22, respectively. At this time, the terminal fittings T2 are placed so that the branch wire L2 is forward of the terminal fitting T2 and parallel to the front-to-rear direction. Next, a screw Sc is passed through the screw insertion hole HS provided in the terminal fitting T2 and the screw insertion hole HS provided in the other side of the connection portions 25 of the fuses H21 and H22, and screwed into the nut N fixed to the front side of the nut fixing portions 229LB provided on the upper and lower surfaces of the front end portion 222LB. This fastens the fuses H21 and H22 and the terminal fitting T2 together to the first resin block 22LB.

[0065] The terminal fitting T2 is also placed on the side plate portion 236B. At this time, the terminal fitting T2 is similarly placed so that the branch wire L2 is in front of the terminal fitting T2 and parallel to the front-to-rear direction. Next, the screw Sc is screwed into the screw insertion hole HS provided in the terminal fitting T2 and into the nut N fixed to the rear side of the nut fixing portion 229LB provided on the left side surface of the front end portion 222LB. This fastens the first bus bar 23LB and the terminal fitting T2 together to the first resin block 22LB.

[0066] Furthermore, with the shank of the bolt B passing through the screw insertion hole HS of the terminal fitting T1, the terminal fitting T1 is placed on the upper plate portion 231LB of the first bus bar 23LB. At this time, the terminal fitting T1 is placed so that the main wire L1 is behind the terminal fitting T1 and is parallel to the front-to-rear direction. Next, when the nut N is screwed onto the bolt B, the first bus bar 23LB and the terminal fitting T1 are fastened together to the first resin block 22LB. Through the above assembly process, the first block assembly 2LB is completed.

[0067] The second block assembly 2RB is assembled in the same manner. The assembly of the second block assembly 2RB can be explained by replacing "first" with "second," "L" with "R," and "left" with "right" in the assembly of the first block assembly 2LB described above, so a detailed explanation will be omitted here.

[0068] In the second block assembly 2RB, only the attachment of the terminal fittings T1 is different, so this will be explained here. The terminal fittings T1 are placed on the upper plate portion 231RB of the second bus bar 23RB. At this time, the terminal fittings T1 are placed so that the main wires L1 are rearward of the terminal fittings T1 and parallel to the front-to-rear direction. Next, a screw Sc is passed through the screw insertion hole HS provided in the terminal fitting T1 and the rear side of the screw insertion hole HS provided in the upper plate portion 231RB, and is screwed into a nut N fixed to the rear side of the nut fixing portion 227RB provided on the upper surface of the rear end portion 221RB. This fastens the second bus bar 23RB and the terminal fittings T1 together to the second resin block 22RB.

[0069] Next, the first block assembly 2LB and the second block assembly 2RB are attached to each other. The first and second block assemblies 2LB and 2RB are brought close to each other in the left-right direction. Then, the locking arm 224LB provided on the first resin block 22LB is engaged with the locking portion 225RB provided on the second resin block 2RB, and the locking portion 225LB provided on the first resin block 22LB is engaged with the locking arm 224RB provided on the second resin block 2RB. This allows the first block assembly 2LB and the second block assembly 2RB to be attached side by side in the left-right direction.

[0070] Next, the fuse H1 is attached. The connection portion 25 of the fuse H1 is placed on the upper plate portion 231LB of the first bus bar 23LB and the upper plate portion 231RB of the second bus bar 23RB, respectively. A screw Sc is passed through the screw insertion hole HS provided in the connection portion 25 of the fuse H1 and the screw insertion holes HS on the front sides of the upper plate portions 231LB and 231RB, and then screwed into a nut N fixed to a nut fixing portion 227LB provided on the front side of the rear end portion 221LB. This tightens the first bus bar 23LB, the second bus bar 23RB, and the fuse H1 to the first and second resin blocks 22LB and 22RB.

[0071] In the second embodiment described above, the first conductive portion 21LB is composed of the first bus bar 23LB and two fuses H21 and H22, and the second conductive portion 21RB is composed of the second bus bar 23RB and two fuses H21 and H22. However, this is not limited to this. The first conductive portion 21LB may be composed of the first bus bar 23LB and three fuses H21, H22, and H23, as shown in FIG. 11 . The second conductive portion 21RB may be composed of the second bus bar 23RB and three fuses H21, H22, and H23, as shown in FIG. 12 . In the second embodiment, the front sides of the fuse accommodating portions 228LB and 228RB and the nut fixing portions 229LB and 229RB provided on the left and right sides of the front end portions 222LB and 222RB were not used. However, in the examples shown in FIGS. 11 and 12 , these portions are used. Terminal fittings T2 attached to the left and right sides of the front end portions 222LB and 222RB are connected to the first bus bar 23LB and the second bus bar 23RB via a fuse H23.

[0072] According to the second embodiment described above, the first resin block 22LB is provided with a locking arm 224LB and a locking portion 225LB that lock onto the second resin block 22RB, and the second resin block 22RB is provided with a locking portion 225RB and a locking arm 224RB that lock onto the locking arm 224LB and the locking portion 225LB. This allows the first resin block 22LB and the second resin block 22RB to be directly locked together, eliminating the need for a joint block 3 and reducing the number of parts.

[0073] According to the second embodiment described above, the terminal fitting T2 attached to the branch wire L2 is disposed on the left side of the first resin block 22LB, one of the outer surfaces facing each other in the left-right direction, which is the side farther from the second resin block 22RB, and the terminal fitting T2 is disposed on the right side of the second resin block 22RB, one of the outer surfaces facing each other in the left-right direction, which is the side farther from the first resin block 22LB. This prevents the terminal fitting T2 from being sandwiched between the first resin block 22LB and the second resin block 22RB, thereby enabling miniaturization.

[0074] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0075] For example, in the above-described embodiment, the fuse H1 is used as the third conductive part, but this is not limiting, and a bus bar may also be used.
