ができる。Further, as shown in FIG. 4, the lever member 15
The rotation operation of the operation portion 17 is a halfway operation incomplete rotation operation, that is, the locking projection 17a of the operation portion 17 of the lever member 15.
Is not completely locked to the locking claw 12b of the lever support portion 12, the upper end portion 2 of the lower cover 20 is
If the lower end portion 30b of the upper cover 30 is to be fitted to 0b, the tip end side of the detection rib 31 of the upper cover 30 interferes with the outer peripheral surface 16c of each cam side plate 16 of the lever member 15 and the upper cover 30 is fitted. Therefore, it is possible to easily detect the abnormality of the intermediate fitting between the connector portion 13 of the connection box body 11 and the mating connector 21 of the lower cover 20. After this detection, the lever member 15 is moved to its operating portion 17
By rotating the locking protrusion 17a of the connector until it is completely locked by the locking claw 12b of the lever supporting portion 12, the connector portion 13 of the connection box body 11 and the mating connector 21 of the lower cover 20 are fitted together. The connector 13 and the mating connector 21 can be surely prevented from being halfway fitted to each other, and the connector fitting failure, that is, the contact failure between both terminals of the connector portion and the mating connector can be reliably performed. Can be prevented.

Since the detection rib 31 is integrally formed at a position facing the introduction opening 16c of the cam groove 16a of the cam side plate 16 of the lever member 15 of a, the connector portion 13 of the connection box body 11 is formed.
And the mating connector 21 of the lower cover 20 can be reliably engaged, and the connector portion 13 and the connector 21
It is possible to reliably prevent a contact failure between the two terminals.
Further, it is possible to further reduce the number of parts and the cost.

る。As described above, according to the first aspect of the invention, when the lever member is not completely rotated in the connector fitting direction, the upper portion of the junction box body is located on the upper surface side in the uncompleted rotation operation. If you try to fit the cover, the detection protrusion of the upper cover interferes with the outer periphery of the cam side plate of the lever member and you cannot fit the upper cover, so the connector part of the junction box body and the mating connector of the lower cover It is possible to easily detect an abnormality in halfway fitting. As a result, the connector part of the connection box body and the mating connector of the lower cover can be securely fitted to each other, and the midway mating of these connector part and the mating connector occurs, that is, between both terminals of the connector part and the mating connector. It is possible to reliably prevent the contact failure.

The upper cover can be fitted on the upper surface side of the junction box body, and the detection projection of the upper cover can function as a stopper for the lever member to fix the lever member at the position where the rotation operation in the connector fitting direction is completed. For,
It is possible to reliably prevent disengagement of the connector portion of the connection box body and the mating connector of the lower cover.
