Since the shell member can be rotated with respect to the insulating housing, for example, the shell member cannot be used for fixing the connector device to the main wiring board, and the connector device is separately used as the main wiring board. It is necessary to provide a member (hold-down member) for fixing, which increases the manufacturing cost of the connector device. Further, the shell member is rotated with respect to the insulating housing so that the shell member is in a depressed position with respect to the insulating housing, whereby the locking protrusions in the locking means formed on a part of the shell member are formed on the insulating housing. When projecting into the plate member insertion portion provided in the insulating housing through the formed insertion hole, the shell is caused by, for example, rattling of a rotating shaft that rotates the shell member with respect to the insulating housing. The locking projection in the locking means that rotates with the member causes a positional shift with respect to the insertion hole formed in the insulating housing, and cannot protrude into the plate-like member insertion portion through the insertion hole. There is a possibility that the wiring plate member inserted into the plate member insertion portion cannot be locked. Further, the state in which the wiring plate-like member inserted into the plate-like member insertion portion by the locking projection in the locking means is locked is that the locking projection is engaged with the wiring plate-like member by the elasticity provided by the locking means. When the elasticity of the locking means deteriorates, the locking of the wiring plate member inserted into the plate member insertion portion by the locking protrusion is not properly performed. There is a risk of it.
