Fig. 2 is the exploded perspective view of embodiment of the invention switch enclosure shown in Figure 1;
Fig. 3 is the stereogram that the major part of above-mentioned a kind of switch enclosure of the prior art is shown;
Fig. 4 is the part forward sight sectional drawing that the major part of another kind of switch enclosure in the above-mentioned prior art is shown.
Fig. 1, Fig. 2 show the switch enclosure 10 of one embodiment of the invention.In switch enclosure 10, tabular planar substrates 13 (wiring plate) is loaded in the installing space of being made up of lower casing portion and last housing department 12.Electric current distribution bus bar 14, relay 15 and microcomputer 16 are installed on the upper surface of substrate 13.
Total line 14 is made of a laminar metallic plate, is installed in the substrate 13, and makes the upper surface of the Width of total line 14 perpendicular to substrate 13.The cross section is respectively V-arrangement and L shaped mounting portion 14a, 14b makes by the side that approaches an end of total line 14 is holded up.Intelligent power switch 17 is fixed on mounting portion 14a, the 14b by unshowned screw thread among Fig. 2, and V-arrangement mounting portion 14a provides the groove of an installation switch 17 so that and three sides of this switch contact.Similarly, L shaped mounting portion 14b provide a kind of and switch 17 two contacted ways of contact in side.In the side of the relative switch 17 with 14b of mounting portion 14a, fin 19 links to each other with 14b with mounting portion 14a by dull and stereotyped 20, these flat board 20 electric insulations, but can conduct heat.
An end of total line 14 with it one make a power supply supply input chip part 21, and 22 make an end 22 with it integratedly at the other end of total line 14.In a position, stretch out a port 23 with external communications from the side of last housing department 12 corresponding to contact 21.Switch enclosure 10 makes connector contact and be connected to contact part 21 by connector being inserted port 23.Be in the position corresponding to end 22 to do on the upper surface of housing department 12 and have a plurality of shell portions 25 of holding up that are used to insert the jack 24 of mini fuse silk 26, the terminal 27 of each fuse 26 can make this terminal 27 link to each other with end 22 by fuse 26 is inserted in the jack 24.
