Multi-class butt joint type unshielded twisted pair

The utility model discloses a multi-class butt joint type unshielded twisted pair which comprises a connector, a wire body and a fixed twisted pair storage box, the connector is fixed at one end of the wire body, the wire body is coiled in the fixed twisted pair storage box, and the fixed twisted pair storage box is fixedly connected with the other end of the wire body. The outer wall of the backface of the connector is attached to the switch B and compresses the switch B under the tension action of the wire body, so that the switch B is in a trigger state for a long time, operation of the motor cannot be caused even if an operator touches the switch A by mistake, use is safer, and meanwhile pulling of the wire body caused by continuous operation of the motor in a wire winding saturated state is effectively avoided; the service lives of the joint and the wire body are prolonged; during take-up, the switch A is pressed, the motor operates to drive the winding shaft to rotate reversely,the wire body is pulled a
