By this structure, main body 60 is mutually fastening by fastening bolt 91 with auxiliary body 90.This makes it possible to prevent the auxiliary body 90 that can be caused by the vibrations of motor vehicles in addition from removing.
When main body 60 fits together with auxiliary body 90, as shown in Figure 6, the auxiliary terminal 94 of auxiliary body 90 is directly assembled to the main terminal 66 of main body 60.Therefore, main printed circuit board 64 firmly connects mutually with auxiliary printing circuit board 93.
With reference to Fig. 7, electric power is supplied to auxiliary body 90 from the input/output circuitry the lower surface of main body 60 through being arranged on main body 60 and connector 68.
Different from prior art terminal box, do not need the additional connector being provided for supplying electric power to auxiliary body 90.Therefore, the general structure changing terminal box is not needed.Therefore, do not need again to manufacture terminal box when adding option.This makes existing terminal box can be used in a kind of new motor vehicles.
The process of assembling junction box assembly structure according to first embodiment of the invention will be described now.
First, as shown in Figure 3, upper body 92, auxiliary printing circuit board 93 and lower body 96 fit together to obtain auxiliary body 90.Then, auxiliary body 90 seated connection is on the auxiliary body installation portion 69 of main body 60.Auxiliary body 90 utilizes fastening bolt 91 to be fixed to main body 60.The combination of main body 60 with auxiliary body 90 is arranged in housing 80.After this, upper cover 70 and housing 80 fit together.Thus, the assembling process of junction box assembly structure is completed.
According to the present invention, several functions can be added when not changing the overall dimension of terminal box.
In junction box assembly structure, main terminal box provides common functions, and assistant junction box provides additional function.Therefore, different optional functions can be added into single terminal box by junction box assembly structure.
And this junction box assembly structure can share to different types of motor vehicles and simplify terminal box.
And this junction box assembly structure can reduce exploitation and the manufacturing cost of terminal box.
< second execution mode >
Fig. 8 shows junction box assembly structure second embodiment of the invention.With reference to Fig. 8, comprise main body 60 according to the junction box assembly structure of the second execution mode and be arranged in a pair auxiliary body 90 at relative both lateral sides place of main body 60.
Second embodiment of the invention, two auxiliary bodies 90 can be mounted to main body 60.Therefore, compared with the first execution mode, more function can be added into terminal box.
And, as shown in Fig. 9 c, even if two auxiliary bodies 90 are mounted to main body 60, also only increase the size of upper cover 70 a little.The shape of junction box assembly structure does not significantly change.Specifically, the size that be arranged on the housing 80 in engine room remains unchanged.Therefore, the layout changing engine room is not needed.
Although attached not shown, multiple auxiliary body can be arranged on three of main body or four sides.
Other structure according to the junction box assembly structure of the second execution mode constructs identical with those of the junction box assembly structure according to the first execution mode.
