8, the stability of the bus bar 75 on the bus bar circuit board is slightly deteriorated, the swing of the terminal 73 tends to increase, and the dimensional variation S 4 in the swing direction (width direction) of FIG. Even if the size variation S 3 is about the same as the example, the opening area of the electrical contact portion (not shown) of the female terminal of the mating connector (not shown) is necessarily small. , The insertion property to the mating terminal becomes poor, and the mating between the male and female connectors is not performed smoothly,
When the connector mating force (insertion force) increases, in the worst case,
There is a concern that the male and female terminals or the male terminal 73 may collide with the front end of the mating connector housing, causing the terminal 73 to be deformed or damaged. Further, before the connector fitting, due to the inter-terminal pitch P 2 narrow, there is concern that the terminal 73 between the male mold adjacent could contact.
