Above-mentioned shell and above-mentioned casket module 5 have constituted " framework " of the present invention.In addition, in the present embodiment, shell and casket module 5 are that split forms, but in the present invention, shell and casket module 5 also can be integrally formed.
Above-mentioned casket module 5 is made of synthetic resin, forms bulk.On this casket module 5, be provided with bolt assembly installation portion 6 that bolt assembly 2 is installed and the electronic component mounting part 8 that a plurality of electronic components such as relay, fuse, connector are installed.In addition, in the side of casket module 5, be provided with the fastener 9 that engages to above-mentioned shell.In addition, the formation about bolt assembly installation portion 6 is described hereinafter.
Shown in Fig. 4 waited, above-mentioned bolt assembly 2 comprised the metal bolt 3 with head 31 and axial region 32, and the roughly rectangular resin component 4 that is fixed on the head 31 of bolt 3.As shown in Figure 1, by this bolt assembly 2 is installed on the bolt assembly installation portion 6, pass at axial region 32 under the state of the bolt hole 70 that is arranged on the busbar 7, this bolt assembly 2 is outstanding from the upper surface of casket module 5.By not shown nut is screwed together on the axial region 32,2 pairs of terminal (not shown) and busbars 7 between above-mentioned nut and head 31 of this bolt assembly are fixed, and keep the state that is electrically connected of above-mentioned terminal and busbar 7.In addition, above-mentioned terminal is meant the terminal of the end that is connected power line, and this power line is from busbar 7 power supplies of power supplys such as storage battery, alternating current generator to electrical junction box 1.
Above-mentioned busbar 7 is to distribute to many electric wires (not shown) via relay, fuse, connector etc. by being electrically connected the electric power imported with the terminal that is connected in power line, by metallic plate being carried out the Wiring member that punch process etc. obtains.Shown in Fig. 3 waits, on this busbar 7, be provided with: be positioned at bolt assembly installation portion 6, terminal connecting portion 71 superimposed and that be electrically connected with this terminal with the terminal that is connected in power line; Be positioned at electronic component mounting part 8, and the electronic component connecting portion 72 that is electrically connected with electronic components such as relay, fuse, connectors.In addition, terminal connecting portion 71 forms tabular, and is provided with bolt hole 70.
As shown in Figures 2 and 3, above-mentioned bolt assembly installation portion 6 comprises: the encirclement wall 10 that the resin component 4 of bolt assembly 2 is surrounded; Be arranged on the inner surface that surrounds wall 10, card is only inserting on the bolt assembly 2 of the inboard that surrounds wall 10 below surrounding wall 10, and a pair of card that supports above-mentioned bolt assembly 2 ends sticking department 11; With the inner surface that is arranged on encirclement wall 10, and be configured in the slip-off preventing sticking department 12 that card ends the below of sticking department 11.
Above-mentioned encirclement wall 10 is made of four walls, forms square tube shape.As shown in Figure 2, above-mentioned a pair of card ends sticking department 11, on two the relative walls in surrounding wall 10, is provided with one respectively.Above-mentioned a pair of card end sticking department 11 form can strain the arm shape, extend obliquely upward from the inner surface that surrounds wall 10.End in the lower end of resin component 4 by the leading section card that above-mentioned a pair of card is ended sticking department 11, end 11 pairs of bolt assemblies 2 of sticking department by above-mentioned a pair of card and support.
The only wall portion of sticking department 11 of card that is not provided with in surrounding wall 10 is provided with an above-mentioned slip-off preventing sticking department 12.As shown in Figures 2 and 3, ended by a pair of card at bolt assembly 2 under the state of locking part 11 supportings, this slip-off preventing sticking department 12 does not contact with bolt assembly 2.As shown in Figure 5, the card that ends sticking department 11 and resin component 4 when a pair of card only gets loose, make bolt assembly 2 move to a pair of card when ending the below of sticking department 11,, come off from casket module 5 to prevent above-mentioned bolt assembly 2 by this slip-off preventing locking part 12 being connected to the lower surface of resin component 4.
In addition, as shown in Figure 5, under the state of slip-off preventing sticking department 12 and the lower surface butt of resin component 4, this slip-off preventing sticking department 12 is set at the front end that makes axial region 32 and is positioned at the position of passing bolt hole 70 and being higher than the surface of terminal connecting portion 71.
And the both sides at the slip-off preventing sticking department 12 of above-mentioned encirclement wall 10 are provided with a pair of slit 13.Thus, when bolt assembly 2 inserts when surrounding walls 10 inboard, surround part between a pair of slit 13 in the wall 10 by bolt assembly 2 pushings and crooked laterally.
Then, with reference to Fig. 4 the number of assembling steps of above-mentioned electrical junction box 1 is described.At first, busbar 7 is installed to shell and is on the casket module 5 of released state.Secondly, above-mentioned electronic component is installed on each electronic component mounting part 8, the electronic component connecting portion 72 of this electronic component and busbar 7 is electrically connected.
Then, shown in the arrow C of Fig. 4, bolt assembly 2 is inserted the inside that surrounds wall 10 from the below of casket module 5.At this moment, initial, resin component 4 and slip-off preventing locking part 12 butts, the part between a pair of slit 13 in the encirclement wall 10 is to the outside curve of surrounding wall 10.Then,, make bolt assembly 2 cross slip-off preventing sticking department 12, the part between a pair of slit 13 that surrounds in the wall 10 is returned to crooked preceding state by bolt assembly 2 is further inserted upward.
Then, by bolt assembly 2 is further inserted upward, bolt assembly 2 makes a pair of card end sticking department 11 to surrounding wall 10 lateral bending songs, self is ended between the sticking department 11 from above-mentioned a pair of card pass through, and the leading section card that a pair of card is ended sticking department 11 ends the lower end at resin component 4.Like this, bolt assembly 2 is installed on the bolt assembly installation portion 6.In addition, by bolt assembly 2 is installed on the bolt assembly installation portion 6, make axial region 32 pass the bolt hole 70 of terminal connecting portion 71.
Then, casket module 5 is installed in the shell.Then, the terminal and the terminal connecting portion 71 that are connected in power line is superimposed, nut is screwed to axial region 32, above-mentioned terminal and terminal connecting portion 71 are electrically connected.At last, the top cover body is installed on the shell.Through such step, electrical junction box 1 assembled finishing.
In addition, in electrical junction box 1, under the medium situation of the process of assembly process or conveying, when axial region 32 has been applied in the power that is higher than set point, the card that then a pair of card ends sticking department 11 and resin component 4 only gets loose, and bolt assembly 2 finally might move to the below that a pair of card ends sticking department 11.In this case, owing to the effect of slip-off preventing sticking department 12 makes bolt assembly 2 be prevented from and can not come off from casket module 5, so, by controlling and pick up axial region 32 from the upper surface side of casket module 5, can make a pair of card end locking part 11 and only recover card again with resin component 4 with finger or pliers etc.
In addition, above-mentioned execution mode has only been represented representative embodiment of the present invention, and the present invention is not limited to above-mentioned execution mode.That is, in the scope that does not break away from purport of the present invention, can carry out various distortion.
