The working principle is as follows:

when the lock core is used, the cable 9 firstly penetrates through the through hole to be connected into the positioning cover 4, then the positioning cover 4 is screwed, the cable 9 is fixed by utilizing the contraction effect of the conical threads, the head of the cable 9 is just touched with the lock core 2 at the moment, and the preparation work is finished as shown in figure 1.

When two cables 9 are butted, the plugging ends of two connector bodies 1 are plugged, as shown in fig. 5, in the plugging moving process, the second limiting surface 19 touches the control rod 6 and pushes the control rod 6 to swing, so as to overcome the first spring 24 to pull the lock core 2 outwards, so that the front end of the lock core 2 extends out, at this time, the limiting ball 7 is simultaneously positioned in the first limiting hole 111 and the limiting through hole 33 to limit the linkage frame 3, so that the linkage frame 3 is kept still and the tool rest 21 slides in the linkage frame 3, so under the action of the first inclined surface 34 on the linkage frame 3, the two ring cutters 22 are pushed to respectively overcome the first torsion spring 23 to rotate until the two ring cutters 22 are combined to perform ring cutting on the insulating skin outside the cables 9, as shown in fig. 5, after the insulating skin of the cables 9 is cut circularly, the two connector bodies 1 are continuously pushed to be plugged, and then drive the lock core 2 to continue moving outward, make the lock core 2 stretch into the lock core groove 13 on the opposite connector body 1, the lock core 2 contacts with the linkage frame 3 and pulls the linkage frame 3 to move together in this process, when the lock core 2 contacts with the linkage frame 3, the first spacing hole 111, the spacing through hole 33 and the second spacing hole 211 are just communicated, thus make the spacing ball 7 move and enter the second spacing hole 211, namely the knife rest 21 and the linkage frame 3 are spacing-linked, and then drive the linkage frame 3 to move when the lock core 2 moves, and when the contact connecting rod 31 contacts with the first spacing surface 18, the first spacing surface 18 pushes the contact connecting rod 31 to overcome the second torsion spring 32 to rotate and clamp towards the middle, meanwhile the ring cutter 22 always moves outward and is in the closed state along with the lock core 2 in this process, and then drive the cut-off insulation skin to move together to expose the metal core of the cable 9, therefore, when the contact link 31 is folded towards the middle, the metal core of the cable 9 is clamped, so that the contact point 311 is communicated with the metal core of the cable 9, and because the connection point 312 and the contact point 311 are communicated inside the contact link 31 and the connection point 312 is respectively connected with the contact probe 51 and the contact pinhole 52 through the conducting wire 8, when the connector bodies 1 on two sides are completely butted, the corresponding contact probe 51 and the contact pinhole 52 are inserted, so that the circuits on two sides are communicated, and meanwhile, the lock cylinders 2 on two sides are just respectively inserted into the lock cylinder grooves 13 of the other side, the lock cylinder 2 pushes the second inclined surface on the positioning pin 15 to overcome the second spring 16 to move, until the positioning pin 15 is aligned with the positioning hole 26, the positioning pin 15 is pushed to be clamped into the positioning hole 26 under the restoring action of the second spring 16 so as to lock the lock cylinders 2, namely, the two connector bodies 1 are locked, and the connection of the cables 9 on two sides is completed, as shown in fig. 6.

When the two connector bodies 1 need to be separated when a circuit fails, the positioning pins 15 on the two connector bodies 1 are pulled outwards simultaneously by overcoming the second spring 16, so that the lock cylinders 2 on the two sides are unlocked simultaneously, at the moment, the lock cylinders 2 are pushed to move inwards under the action of the first spring 24, the control rod 6 is further driven to rotate to push the second limiting surface 19 to separate the two connector bodies 1, at the moment, under the action of the limiting ball 7, the linkage frame 3 and the tool rest 21 are still in a limited state, so that the lock cylinders 2 move inwards to drive the linkage frame 3 to move together, when the contact connecting rod 31 is separated from the first limiting surface 18, the contact connecting rod 31 is driven to rotate and separate under the action of the second torsion spring 32, so that the contact connecting rod is disconnected with the metal inner core of the cable 9, and at the same time, after the contact connecting rod 31 is separated, the contact point 311 is in contact with the inner wall surface 17 of the connector body 1 for limiting, at the moment, the first limiting hole 111, the limiting through hole 33 and the second limiting hole 211 are just communicated, the linkage frame 3 can not move continuously, as shown in fig. 5, the limiting ball 7 enters the first limiting hole 111 to position the linkage frame 3, then the lock cylinder 2 continues to move inwards under the action of the first spring 24, the ring cutter 22 is controlled to rotate and separate under the action of the first torsion spring 23, so that the cable 9 is loosened completely, the lock cylinder 2 is also retracted completely, namely, the connector bodies 1 on the two sides are separated completely, and then the positioning cover 4 is unscrewed to detach the cable 9 for maintenance, so that the detachment of the connector body 1 is completed.
