When wires are routed inside the electrical junction box, a wire guide is provided on the insulating plate, wires are routed along the wire guide, and a pressure contact terminal is press-connected to the wire. In many cases, the other end of the terminal protrudes into a fuse housing portion or a relay housing portion formed on the surface of the case and is connected to a fuse, a relay, or the like.
For example, in the electrical junction box 1 disclosed in Japanese Patent Laying-Open No. 2005-51877 (Patent Document 1), as shown in FIG. 9, the insulating plate 2 in which the electric wires 3 are wired in the horizontal direction is accommodated in the case 4. Then, the press contact blade portion 5a at one end of the terminal material 5 for connection with the external circuit is press contact connected to the electric wire 3, and the connection portion 5b at the other end is protruded into the side connector housing portion 6 provided on the side of the case. ing. By fitting a connector (not shown) connected to the end of the external wiring material into this laterally extending connector housing portion 6, the electric wire 3 of the internal circuit and the external wiring material can be connected via the terminal 5. ing.

One end of the pressure contact blade portion 5a must be provided in the vertical direction, while the other end connection portion 5b must protrude into the laterally extending connector housing portion 6 in the horizontal direction. Therefore, it is necessary to bend the terminal material 5 into an L shape, and there is a problem that the number of processing steps and cost increase.
Further, when it is necessary to arrange the height position of the connection portion 5b of the terminal material 5 at substantially the same height as the electric wire 3 for the reason of design of the electric junction box, as shown in FIG. There is a problem that the part 5a side is bent in a U-shape, resulting in a more complicated shape, which further increases the number of processing steps and costs. In Patent Document 1, the terminal material 5 is protruded into the sideways connector housing portion. However, the same problem occurs in the case of the sideways fuse housing portion.

  Moreover, in the electrical junction box 1 provided in Patent Document 1, since the insulating plate 2 for arranging the electric wire 3 is provided and the insulating plate 2 is accommodated in the case 4, the electrical junction box 1 is There is also a problem that the number of parts increases as the size increases.

Therefore, it is possible to make the press contact terminal into a flat shape that does not need to be bent, and to reduce the processing man-hour and cost of the press contact terminal.
In addition, since the wires that are routed inside the case are not directly on the insulating plate, but are wired directly on the case inner surface along the guide pins protruding from the inner surface of the case, an insulating plate for the wiring guide becomes unnecessary, The number of parts can be reduced and the electrical junction box can be reduced in size.

The component housing portion including the fuse housing portion is composed of a housing space surrounded by the lower case and the upper case and defined by the partition wall projecting from the lower case, and the fuse case is housed in the housing space.
The fuse case has a structure in which a plurality of fuse cavities for inserting one fuse each are arranged in parallel, and is inserted and fixed from the front end opening of the fuse housing portion. The press contact terminal is held in a terminal holding portion provided in each fuse cavity of the fuse case, and each press contact terminal held by the terminal holding portion when the fuse case is inserted and fixed to the fuse housing portion is connected to the electric wire. It is set as the structure which press-connects to an edge part.

Moreover, in FIG.4 and FIG.5, the electric wire w wired is partially abbreviate | omitted.

Next, a method for assembling the electrical junction box 10 will be described.
First, as shown in FIG. 2, the wire w is routed horizontally in the wire routing region S of the lower case 11, the terminal side on the fuse housing portion side is bent in an inverted U shape, and the wire insertion of the partition wall 11b is performed. It passes through the notch 11c and passes through to the fuse accommodating part 13 side, and the terminal part wa of the electric wire w along the partition wall 11b faces downward on the fuse accommodating part 13 side. This downward terminal portion wa is further passed through the electric wire insertion hole 11e to position and fix the terminal.
Next, the bus bar 20 laminated on the insulating plate 21 is disposed on the upper layer of the electric wire w, and the tuning fork terminal portion 20a of the bus bar 20 is protruded into the fuse housing portion 13.

  Further, the electric wire w to be arranged in the electric wire arrangement region S of the lower case 11 is bent at the position of the guide pin 11k and arranged along the required wiring path, and the terminal insertion fixing portion 11h is provided. At the position, the press contact terminal 31 is driven in from above, and the electric wire w and the press contact terminal 31 are press connected. The pressed contact terminal 31 is fixed by the terminal insertion fixing portion 11h. The tuning fork terminal portion and the tab-like terminal portion protruding above the press contact terminal 31 are protruded upward through a through-hole formed in the laminated body when the laminated body of the bus bar 20 and the insulating plate 21 is disposed on the upper layer. ing.

Next, the upper case 12 is assembled to the lower case 11 to form the fuse accommodating portion 13 surrounded by the lower case 11 and the upper case 12. The fuse case 40 is inserted and fixed from the front end opening of the fuse accommodating portion 13. In each fuse cavity of the fuse case 40, a press contact terminal 30 for connecting a fuse is held in advance.
When the fuse case 40 is inserted into the fuse housing portion 13 and locked together, the press contact blade of the horizontal wire press contact portion 30a of the press contact terminal 30 housed in the fuse cavity 41 cuts the insulation coating of the downward end portion wa of the wire w. Then, it is press-contacted with the conductor of the electric wire w.
At the same time when the fuse case 40 is inserted and fixed, the tuning fork terminal portion 20 a of the bus bar 20 protrudes into the fuse cavity 41 of the fuse case 40.
As a result, the tuning fork terminal portion 20a of the bus bar 20 is located above the fuse cavities 41 arranged in parallel with the fuse case 40, and the tuning fork terminal on the other end side of the press contact terminal 30 connected to the electric wire w below the opposite. The part 30b will be located.

  Finally, when the fuse 50 is inserted into each fuse cavity 41 of the fuse case 40, the tuning fork terminal portion 30b of the press contact terminal 30 is connected to the tab-shaped output terminal 50a of the fuse 50, while the tab-shaped input terminal of the fuse 50 is connected.

According to the electrical junction box having the above-described configuration, the electric wire w that is horizontally wired along the inner surface of the bottom wall of the lower case 11 is moved over the partition wall 11b that protrudes from the lower case 11 and is vertically lowered in the fuse accommodating portion 13. Since it is positioned and held in the direction, it can be press-connected with the wire press-contact portion 30a of the press-contact terminal 30 in the horizontal direction in the lateral fuse housing portion. Thus, both the pressure contact direction of the pressure contact terminal 30 with respect to the electric wire w and the pressure contact direction of the pressure contact terminal 30 with respect to the output terminal 50a of the fuse 50 accommodated in the fuse accommodating portion 13 can be made horizontal. Therefore, the press contact terminal 30 can be formed into a flat shape that does not require bending, and the processing man-hours and cost of the press contact terminal 30 can be reduced.
Further, the wire w that is three-dimensionally wired along the partition wall 11b of the lower case 11 is routed through the wire insertion notch 11c, and the distal end side is further passed through the wire insertion hole 11e to fix the wire w. For this reason, the wire pressure contact portion 30a of the pressure contact terminal 30 can be reliably pressure-connected to the electric wire w only by pushing the pressure contact terminal 30 from the side.

  Further, the electric wire w is guided directly to the inner surface of the bottom wall of the lower case 11 by a guide pin 11k, and the press contact terminal 31 for press-connecting with the wired electric wire w is press-connected from above to protrude from the lower case 11. Since it can be fixed by the provided terminal insertion fixing portion 11h, an insulating plate for arranging the electric wire w becomes unnecessary, and the electrical connection box 10 can be reduced in size by not accommodating the insulating plate in the case. .
