As described above, according to the cable connector attaching / detaching tool of the present invention, the base bracket and the operating lever can be grasped with one hand, and the operating lever can be rotated with respect to the connector extracting lever. For example, the connector extraction lever can be swung with respect to the base bracket while resisting the urging force of the urging means as the operation lever rotates, and the connector extraction lever and the operation lever can be attached to the base bracket. It is possible to provide a state in which the tool is in a state of being substantially parallel to the face down, the height dimension of the tool in the vertical direction is as small as possible, and an inexpensive tool for attaching and detaching a cable connector can be provided.

Moreover, the connector engaging body is engaged with the receptacle connector, the first engaging portion of the connector extracting lever is engaged with the slide ring of the cable plug connector, and the connector extracting body is released by releasing the hand from the operating lever. Since the lever for the connector swings with respect to the base bracket by the biasing force of the biasing means, the slide ring of the cable plug connector is released while the locked state of the lock-type cable connector is released along with the swing of the connector extraction lever. The cable plug connector can be easily pulled out from the receptacle connector by swinging it against the connector body, and the cable plug connector is not deformed or damaged because it does not apply unnecessary force to pull out the cable plug connector from the receptacle connector. You can prevent the cable plug connection Since the head contacts the stopper piece of the base bracket, the cable plug connector can be clamped between the stopper of the base bracket and the lever for removing the connector, and the stopper piece of the base bracket can be used for the connector extracting lever of the cable plug connector. Since it is prevented from dropping from the first engaging part of the cable plug connector, there is no risk of the cable plug connector dropping or coming into contact with other parts and being damaged, and it is possible to remove the cable plug connector in a narrow space from the receptacle connector with one hand. Can be done reliably.

According to the cable connector attaching / detaching tool of the present invention, since the lever lock mechanism locks the operating lever with respect to the base bracket, the connector extracting lever and the operating lever are attached to the base bracket by the lever locking mechanism. It can be maintained in a state that it is lying in a substantially parallel position to the base bracket, and the connector extraction lever can be released from the base bracket by the urging force of the urging means simply by releasing the lock of the operating lever with respect to the base bracket. Can be swung with respect to.

Further, according to the cable connector attaching / detaching tool of the present invention, the second engaging portion of the connector extracting lever is engaged with the slide ring of the cable plug connector, and the head of the cable plug connector is attached to the operating lever. The cable plug connector can be clamped between the second engaging portion of the connector extracting lever and the pressing piece of the actuating lever simply by abutting against the pressing piece. The slide ring of the cable plug connector, which is prevented from coming off from the second engaging portion by the pressing piece of the operating lever, and is sandwiched between the second engaging portion of the connector extracting lever and the pressing piece of the operating lever. Position above the receptacle connector and slide the cable plug connector's slide ring into the receptacle with the pressing piece of the operating lever. Since it can be pushed into the connector, the cable plug connector can be inserted into the receptacle connector, and if the second engaging part of the connector extracting lever and the pressing piece of the operating lever are separated from the cable plug connector, The plug connector can be easily attached to the receptacle connector in a narrow space with one hand.
