When the metal sheath and/or the sheath protector 10 of the cable in the cross connection box with the unpacking-free detection function needs to be detected, the transmission mechanism 500 can be operated in the first transmission state, so that the detection component 410 is electrically connected with the conductor fixing mechanism 300, and the cross connection mechanism 200 is separated from the conductor fixing mechanism 300, at this time, the detection component 410 is electrically connected with the metal sheath and/or the sheath protector 10 of the cable, and the cross connection mechanism 200 is disconnected from the conductor fixing mechanism 300, so that the metal sheath and/or the sheath protector 10 of the cable can be correspondingly detected through the detection line connected to the outside of the box body 100.

In the aforesaid cross connection case with exempt from to unpack and detect the function, if need detect cable metallic sheath and/or cable sheath protector 10 in the box 100, need not to open the case lid, can reduce fortune dimension personnel's work load and reduce the power off time, and can avoid the problem that the leakproofness because of frequently opening the cross connection case that the case lid brought reduces, and can avoid because of the cross connection case because of the improper problem that causes the cross connection case to soak or wet, thereby prevent that cross connection case insulating properties from reducing or cable sheath protector 10 from damaging. In addition, after the detection of the cable metal sheath and/or the cable sheath protector is completed, the transmission mechanism 500 can be operated in the second transmission state, so that the cross interconnection mechanism 200 is electrically connected with the conductor fixing mechanism 300, and the detection component 410 is separated from the conductor fixing mechanism 300, so that the cross interconnection box can operate normally.
