Conventionally, in order to suppress rattling of the bus bar circuit board 10 in the housing groove 2, the width of the housing groove 2 is further narrowed or the bus bar circuit board 10 is adapted to the application.
When the common substrate 11 of 10 is further complicatedly bent, the end surface of the busbar circuit board 10 having a small area is pressed against the other edge 15 of the busbar circuit board 10. Therefore, the busbar circuit board 10 is inserted with an increase in insertion resistance into the accommodation groove 2. There was a problem that the dressing operation was not smooth. In particular, when using an automatic assembling device or the like, the deterioration of the mountability is a very serious problem. Further, since the inner space of the cover 20 is relatively narrow, the bundled wire 21 may be pressed against the end face of the bus bar circuit board 10 at the other end edge 15 in the punched state. As a result, the insulating coating material of the bundled wire 21 may be damaged by the end surface of the bus bar circuit board 10 and a short circuit may occur.
