CONNECTOR COMING-OFF PREVENTING TOOL, COMMUNITY ANTENNA TELEVISION DEVICE, AND WIRING SYSTEM

PROBLEM TO BE SOLVED: To provide a simple, reliable, and cheap connector coming-off preventing tool. SOLUTION: A locking part is formed around the outer periphery of the cylindrical contact plug hold portion of a connector plug. A connecting portion is formed in the peripheral portion of a case. The connector coming-out preventing tool having an opening at least at one end of the equipment is formed including a space for housing a portion except the face of the case to be mounted to the object through the opening, a recess to which the locking part formed around the contact holding portion of a connector plug is engaged, and fixing means formed in a position opposite to the connecting part formed on the case. The fixing means of the stopper and the connecting means of the case have two mounting states. In one state, the connector plug is removably engaged in a state of the connector plug removably connected to a connector base. In the other state, the recess of the stopper and the stopper of the connector plug are engaged rotatable in the rotating direction of the connector plug, while being locked in the comming-out direction of the connector plug from the connector base for preventing comming-off.
