Each tab 13 protruding into the housing 11 on the side of this junction box
The pitch (spacing) of a must be the same as the pitch (spacing) of each terminal of the female connector to be inserted and connected to this, but the pitch of each tab 13a protruding into the housing 11 conforms to the female connector terminal As shown in FIG. 5, each of the projecting tabs 13a of the upper and middle bus bars is bent and the degree of the bending is changed to set each of the projecting tabs 13a as shown in FIG. The pitch between them is set to a predetermined pitch, or as shown in FIG.
The pitch between the projecting tabs 13a is set to a predetermined pitch by changing the thickness of the insulating plate 15 interposed in the lamination of the thirteen.

In addition, a bus bar having a tab bent at a right angle above the housing and protruding and a bus bar extending linearly and protruding from the side of the housing is laminated with an insulating plate interposed therebetween.
An electrical junction box with an electronic circuit board of -205214 is known.

In addition, the end of the bus bar arranged on the insulating substrate surface was extended straight in a straight line without bending, and a plurality of circuit boards, which were made into parallel male terminals, were stacked and housed in a casing in a state where they were stacked.
The electrical junction box of -28420 is known.

Also, each of the ends of the plurality of busbars is bent to form a plug terminal, and a connector housing for inserting the bent terminal into each of the bent terminals to maintain the laminated state of the laminated board is inserted into the end of the box cover. A plug-in device for a wiring board disclosed in Japanese Utility Model Publication No. Sho 58-7773, which is inserted into a part, is known.

[Problems to be Solved by the Invention] As described above, the pitch of each tab 13a protruding into the housing 11 on the side surface of the connection box is set to a pitch suitable for the pitch of various female connector terminals. If the degree of bending of each protruding tab 13a is variously set as shown in FIG. 5, various molds for molding the bending tab are required, which increases the cost and increases the cost. As shown in the figure, if the thickness of the insulating plate 15 interposed in the lamination of the bus bars 13 is changed to a large thickness, an insulating plate having a thickness larger than the thickness required for insulation is used, and the connection box becomes large. There is a problem that it becomes expensive.

Busbar 13 and insulating plate 15 so that the connection box does not become large
When the number of bus bars 13 to be laminated is reduced as in the connection box 10 shown in FIGS. 7 and 8 in order to reduce the lamination thickness of the The insulating plate 15 must be widened in the width direction and the bus bar must be provided in the expanded width area, and there is a problem that the junction box 10 becomes large in the width direction.

Further, the electric connection box with an electronic circuit board disclosed in the utility model publication and the electric connection box disclosed in the utility model publication are formed by using a laminated insulating plate in order to form tabs extending and protruding on the side surface of the housing at various predetermined intervals. Since there is no other way to change the thickness,
There is a problem that the insulating plate becomes unnecessarily thick and the connection box becomes large and expensive.

Further, the plug-in device for a wiring board disclosed in the above-mentioned utility model publication has a problem that various bent terminal molding dies for setting the pitch of the bent terminals in various ways are required, resulting in an increase in cost.

The present invention solves the above-mentioned problems, and does not require a costly bending tab molding die, and does not need to form a thick or wide insulating plate to be interposed and laminated, and protrudes into the housing. An object of the present invention is to provide a small-sized, low-cost electric connection box in which the pitch of tabs can be adjusted and set to a pitch that matches the pitch of female connector terminals.
