  After the connection box body 3 is positioned along the guide portion 45 as shown in FIG. 4, the switch is pushed to lower the press-fitting tool 41, and the fuses 8 are connected to the fuse mounting holes 12 (see FIG. Press fit into 5). The pressure input is substantially equal to the force required for connection between the tab terminal of the fuse 8 and a not-shown clamping terminal or female terminal in the connection box body.

  When the press-fitting is completed, the first guide jig 5 is removed as shown in FIG. The upper end surface of each fuse 8 is positioned substantially on the same plane as the upper surface 2 a of the fuse mounting portion 2 of the junction box body 3, that is, the upper opening end of each fuse mounting hole 12. The first guide jig 5 (FIG. 4) is returned to the original receiving member 17 (FIG. 1). Then, the next connection box body 3 is set on the receiving tool 4 (FIG. 1), and each fuse is inserted into each fuse mounting hole 12 by the same operation as described above.

  In the above embodiment, the receiver 4 for inserting and setting the junction box body 3 is provided. However, when the junction box body 3 is stable, the junction box body 3 is directly attached to the work table 18 without using the receptacle 4. It is also possible to put it on.

  In the above-described embodiment, the case where three types of fuses 8 are mounted has been described. However, when four types of fuses 8 are used, four second guide jigs 6 and four component storage boxes 10 are used. Similarly, five or more types of fuses 8 can be mounted.

  For example, when an optional fuse (8) is retrofitted to the fuse mounting portion 2 of the junction box body 3, the first guide jig 5 is provided with a number of fuse guide holes 19 excluding the optional fuse. The fuse guide holes 19 of the first guide jig 5 and the total number of fuse guide holes 26 of the second guide jigs 6 are made to coincide with each other. It is also possible to install in the (fuse mounting hole 12).

  Moreover, in the said embodiment, although it comprised so that the cover 9 of the component storage box 10 might be closed compulsorily, between each adjacent component storage box 10 and each 2nd guide jig 6 (receiver 7), for example. A component storage box corresponding to the second guide jig 6 removed from the support 7 with a high partition wall (not shown) between them and with the lid 9 of each component storage box 10 removed (not provided) It is also possible to make the operator recognize 10 by illuminating 10 with a light through the control unit 34 by a signal from the sensor 31. This is effective in inserting the fuse 8 using only the first and second guide jigs 5 and 6 without using the lid 9. In addition, by using each component storage box 10 without the lid 9 and inserting the various fuses 8 with the first guide jig 5 and the plurality of types of second guide jigs 6, the accuracy of preventing erroneous insertion is It is effective though it falls a little.
