In addition, it is an object of the present invention to provide a connector half-fitting detection structure which has a simple structure and allows the fixed-side connector in any direction to perform a blocking action of the half-fitting detection member (the action of the second conventional example).

[0009]

In order to achieve the above object, the present invention provides a plurality of fixed connectors arranged side by side in a connection box body, an insertion connector fitted to the fixed connector, A connector half-fitting detection structure configured to engage with the engagement portion of the insertion-side connector and to be released by the release projection of the fixed-side connector.
The half-fitting detection member is detachably attached to the fixed connector.
In the peripheral wall of the half-fitting detection member, a baffle plate facing the insertion opening of the adjacent fixed connector is protrudingly provided, and it is impossible to insert the adjacent insertion-side connector into the insertion opening with the baffle plate. It is characterized by becoming.

[0010]

When the insertion of the insertion-side connector is incomplete (semi-fitting), the half-fitting detection member is not detached, and the baffle protruding from the half-fitting detection member inserts the adjacent fixed-side connector. Close the opening to disable insertion of the insertion side connector. Therefore, half-fitting of the connector is easily detected. The baffle plate can be protruded in any direction on the peripheral wall of the fitting detection member, and it is possible to freely select which fixed-side connector is to be cut off, that is, which insertion-side connector is to be associated with.

[0011]

FIG. 1 is an exploded perspective view showing an embodiment of a connector half-fit detection structure according to the present invention. In the drawing, reference numeral 1 denotes a connection box body in which a plurality of fixed connectors 2 to 5 are arranged in front, rear, left and right, and 6 denotes an insertion connector to which a half-fit detection member 7 is attached and connected to a central fixed connector 2. , 8 indicate insertion-side connectors connected to the adjacent fixed-side connectors 3.

On the upper end surface 9 of the housing of the fixed connector 2 at the center, a pair of tapered release projections 10, 10 for the half-fit detection member 7 are provided as in the prior art. The half-fit detection member 7 is provided on a peripheral wall 11 surrounding three sides of the insertion-side connector 6 with a flexible locking claw 12 with respect to the release projection 10 and an abutment with an engagement projection 13 with the connector 6 as in the conventional case. Article 1
4 and a baffle plate 16 is provided on one side of the peripheral wall 11 so as to face the insertion opening 15 of the adjacent fixed connector 3.

As shown by chain lines 16 'and 16 "in FIG. 1, the baffle plate 16 can protrude in any direction on the peripheral wall 11 of the half-fitted detecting member 7, and the adjacent fixed connectors 3, 4, and 5 can be provided. selection of whether to correspond to any is free. Incidentally, the connector
