って固定していた。The conventional method of manufacturing an electrical junction box is to first punch out a busbar pattern as shown in Figure 2 from a material, bend it, then cut the bridge 7 and assemble it to the insulating plate 1, or assemble it to the insulating plate and then remove the bridge. 7 was cut and stored in lower case 3 and upper case 4. As a means of assembling the bus bars 2a and 2b onto the insulating plate, as shown in FIG. Alternatively, as shown in FIG. 6, a hole 11 is made on the bus bar 2 and a fixing lip 12 protruding from the insulating plate 1 is used to fix the bus bar 2.
しかしながら上記した電気接続箱の製造方法においては

の寸法′精度と絶縁板の寸法精度が異なるため製品精度
管理が難しく作業性も悪いといった問題点があった。However, in the method for manufacturing the electrical connection box described above, the bus bars of each layer are separately assembled on the insulating plate, which results in a lack of reliability during assembly and increases the load on the assembly equipment. Furthermore, since the bus bar and the insulating plate are integrated in post-processing, the number of man-hours increases. Furthermore, since the dimensional accuracy of the bus bar itself is different from the dimensional accuracy of the insulating plate, there is a problem in that product accuracy control is difficult and workability is poor.

ねたバスバーを絶縁材料で一体成型する。The method for manufacturing an electrical connection box of the present invention will be explained in detail below with reference to FIGS. 1 to 3. First, in the electrical junction box, several types of busbar patterns (Figure 2 is one example) are punched out and bent to form busbars (however, the bridge 7 is not cut) to form internal circuits from the material.
Bus bars 2a 12 of each layer are placed on the jig B13 shown in the figure.
Stack b s 2 c with desired spacing. At this time, in order to keep the interval between the bus bars of each layer constant, use jig B.
Each layer bus bar holding pin 14a, 1 protruding from 13
4b and 14C, and by changing the length of the busbar holding pins, the busbars of each layer 2 a % 2 b
12c interval can be changed as appropriate. Jig B1
After stacking the bus bars 2a, 2b% 2c of each layer on 3, a jig A15 is set, and the stacked busbars are integrally molded with an insulating material using an injection molding machine.

6 into the bridge cut jig 17, and cut the cut pin 1.
Busbar assembly 1 with bridge cut jig 19 provided with 8
The bridge portions 7 of 7 are cut all at once. After that, store it in the lower case and upper case as necessary.
なおブリッジカットは一括して行なうことが好ましいが
、カット位置等の都合によっては２回等に分けて行なっ
てもよい。Although it is preferable to perform the bridge cut all at once, it may be performed in two parts depending on the circumstances such as the cutting position.
