Description of the Related Art For locking a terminal in a connector, a flexible locking arm or a locking projection called a housing lance is provided on the inner wall of the terminal receiving hole, and this is engaged with a terminal inserted into the terminal receiving hole. Although it is common to prevent the back-out, the use of an airbag device or other safety device, together with the use of an airbag device or other safety device, allows the terminal locking, which is a separate component, from the front surface of the connector housing (the mating surface with the mating housing). There has been proposed a device in which a tool is attached so as to further prevent the terminal from coming off.

具付コネクタ。An insulating housing for accommodating a terminal in a terminal accommodating hole penetrating therethrough; a housing lance engaging with the terminal in the terminal accommodating hole to temporarily lock the terminal; A terminal locking tool mounted on the mating surface so as to be capable of rotating forward and backward between a temporary locking position and a final locking position, and engaging with a terminal at the final locking position to perform secondary locking. The terminal locking member is provided with a shaft or a bearing (hereinafter, represented by a shaft) protruding from a board, and an insertion hole for a counterpart terminal connected to the terminal in a radial direction with the shaft as a center is provided; A floating prevention piece and a terminal locking rod are formed to project from inside and outside of the insertion hole, respectively, and the insulating housing has a bearing or a shaft (hereinafter, referred to as a bearing) for the terminal locking tool on the fitting surface. ), And the locking rod temporary accommodation hole communicating with the terminal accommodation hole and the floating A detent is provided for engaging the stop piece, and between the terminal locking member and the insulating housing, a shaft of the terminal locking member and a terminal locking rod are provided with a bearing and a locking rod temporary receiving hole of the insulating housing. At the same time, when the floating prevention piece engages with the detent, the forward rotation of the terminal locking member is prevented, the terminal locking rod is stopped in the locking rod temporary receiving hole, and the terminal locking member is inserted. And a means for holding the terminal locking tool at the temporary locking position, and the terminal locking tool at the temporary locking position is positively rotated toward the terminal receiving hole to engage the terminal locking rod with the terminal. A connector with a terminal locking member, comprising means for preventing reverse rotation of the terminal locking member to the temporary locking position and holding the terminal locking member at the final locking position when locking is performed.
