The present invention also provides a kind of vehicle that at least one above-mentioned switch enclosure is housed.
Total line is represented a kind of electric current distribution member in the present invention, and normally one, it will be by the power distribution of power input input in many electronic components or circuit.Total line has many outputs usually, can connect elements such as fuse and/or relay box on these outputs.Intelligent power switch is represented a kind of switch that contains electronic equipment in the present invention, and this switch can detect at least one as the electrical quantity of electric current one class passed through and according to the work of this parameter control switch.
With reference to the accompanying drawings a preferred but non-restrictive example of the present invention is described, in the accompanying drawing:
Fig. 1 is the stereogram of embodiment of the invention switch enclosure;
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.
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.
As shown in Figure 2, switch 17 has the connection pin, and this pin inserts in the hole of substrate 13, so just total line 14 is installed in the substrate securely.Pin and wiring electrically contact at the lower surface of substrate 13, and wiring is provided in two surfaces of substrate in a conventional manner, and this does not show in Fig. 2.Wiring also be installed on suprabasil other elements and link to each other, as relay 16, microcomputer 16 and fuse 16.
