8 of short female-female terminals 5-7, male-female terminals 8, long female-female terminals 9-11 and male-female terminals 12 for leading out to
It is necessary to use a total of 10 kinds of terminals, namely, a male-female terminal 13 and a female-female terminal 14 as wire harness connection terminals. Therefore, an increase in component cost due to each type of terminal is unavoidable, and since the length of the terminal to be inserted into the bus bar 3 in the upper case 1 is different, the insertion method cannot be made common and the device cost is extremely high. Expensive.

が高くなる。Assembling the lower case 2 into the upper case 1 is carried out in the manufacturing process of the wire harness, but as shown in FIG. 8, the connection A between the male terminal 15 and the female-female terminal 14 is performed.
Since the structure is such that the connection B between the bus bar 4 and the male-female terminal 12 is performed at the same time, there is a problem in matching and there is a problem that the work is difficult. Further, since the short terminals 5 to 8 and the long terminals 9 to 12 are mixed in the upper case 1, a plurality of protective walls 23 must be provided on the insulating substrate 16 as described above, resulting in unevenness and a complicated shape. Therefore, the molding die cost becomes high.
