When the magnet 8 is in a detection state, the through hole at the upper side of the first sleeve 17 continuously enters air, the second tension spring 24 resets and drives the second slide rod 22 to move downwards through the push disc 23, meanwhile, the clamping plate 28 moves downwards, if the clamping plate 28 is just positioned between two adjacent limit teeth 1601, the clamping plate 28 gradually moves downwards and is clamped between the two adjacent limit teeth 1601, if the clamping plate 28 is not positioned between the two adjacent limit teeth 1601, the lower side of the clamping plate 28 is contacted with the inclined surface of the limit teeth 1601, the inclined surface of the limit teeth 1601 guides the lower side of the clamping plate 28 to enable the clamping plate 28 to move leftwards, in the process of moving the clamping plate 28 leftwards, the clamping plate 28 drives the sealing disc 27 to move leftwards through the pull rod 26, the right side pressure of the sealing disc 27 is reduced, the left side pressure is increased, the air inlet hole of the second sleeve 25 is opened, the air enters the right side of the sealing disc 27 through the air inlet hole of the second sleeve 25, and the air at the left side of the sealing disc 27 is discharged through the air outlet hole of the second sleeve 25, so that the clamping plate 28 can only move leftwards relative to the second sleeve 25, and the right-side tension spring 15 is prevented from moving leftwards (the right-side tension spring 15 is still prevented from moving leftwards due to the fact that the two adjacent limit teeth are still moving to the two limit teeth 15 are positioned between the two adjacent limit teeth and the reset heads 15 and the reset cable 112 is still in a sliding state, and the right-side 15 is prevented from being moved to be in the left and a right-side 15 is still in a state is prevented from being in a state).
After the limiting plate 16 is limited, the left cable head 112 is electrified, the left cable core 1121 transmits current to the right cable core 1121 through the conductive component 111, the current is obtained by an ampere rule (a magnetic field is generated around a conductor with current flowing), the magnetic field is generated around the conductive component 111, the magnet 8 is influenced by the magnetic field to rotate, the magnet 8 drives the extrusion block 9 to rotate 180 degrees through the rotating rod 7, the torsion spring stores force, the extrusion block 9 does not extrude a switch of the miniature power supply 10 any more after rotating, the warning lamp 11 is extinguished, and an operator knows that the two cable cores 1121 are in an electrified state.
When the circuit breaks down, if the cable that joint 1 is connected here is damaged, then left side cable core 1121 no longer carries the electric current to the right, at this moment, can not produce the magnetic field again near conductive component 111, torsion spring reset on the bull stick 7 drives bull stick 7 rotation, extrusion piece 9 rotates 180 and micro-power source 10's touch-press switch contact, warning light 11 lights, when the operating personnel troubleshoots, observe this department warning light 11 and light the back, know that this department circuit goes wrong, need not to use current detection equipment to check gradually, and when the circuit did not break down, micro-power source 10 can not start, thereby the energy saving, avoid the wasting of resources, if need long-range understanding circuit fault position, after micro-power source 10's touch-press switch is triggered, touch-press switch sends the signal to control terminal, control terminal sends the signal to remote control terminal, operating personnel accept signal understanding circuit fault's position, warning light 11 plays the effect of supplementary searching circuit fault this moment.
After the two cable cores 1121 are in the connected state, if the cable head 112 is pulled by an external force instantaneously or other factors move leftwards, taking the left cable core 1121 as an example, the left cable core 1121 moves leftwards from the conductive component 111, but the left cable core 1121 is not completely inserted into the conductive component 111 to generate an arc phenomenon, so that potential safety hazards of a circuit are easily caused, and therefore, the cable needs to be reset in time after the cable core 1121 is pulled by the external force to move leftwards, so that the connection of the circuit is ensured, and the specific operation is as follows: when the cable head 112 moves leftwards, the limiting plate 16 is limited because the clamping plate 28 is clamped between the two adjacent limiting teeth 1601, so that the cable head 112 moves leftwards relative to the trapezoid block 13, the cable head 112 does not squeeze the connecting lantern ring 2 any more, the first spring 3 resets to drive the connecting lantern ring 2 to move leftwards, the connecting lantern ring 2 drives the two triangular blocks 21 to move leftwards, taking the triangular block 21 on the upper side as an example, the triangular block 21 moves leftwards and does not squeeze the wedge block 20 any more, the second spring 19 resets to drive the first sliding rod 18 and the wedge block 20 to move upwards, the push plate 23 moves upwards slowly, the second tension spring 24 is compressed, the clamping plate 28 does not release the limit on the limiting plate 16, so that the limiting plate 16 does not move leftwards in the process of moving the cable head 112, after the cable head 112 stops being dragged by an instant external force, the clamping plate 28 slowly moves upwards to release the limit on the limiting plate 16, the first tension spring 15 resets to drive the internal thread sleeve 12 to move rightwards, meanwhile, the internal thread sleeve 12 drives the cable head 112 to move rightwards through the trapezoid block 13, so that the cable core 1121 is inserted into the conductive component 111 again, the occurrence of an arc phenomenon is avoided, in the process of moving the cable head 112 rightwards, the cable head 112 drives the triangular block 21 to move rightwards through the connecting lantern ring 2, the first spring 3 is compressed, meanwhile, the wedge block 20 is extruded to move downwards, after the cable core 1121 is inserted into the conductive component 111 for a period of time, the clamping plate 28 moves downwards to be clamped between two adjacent limiting teeth 1601, the limiting position of the limiting plate 16 cannot continue to move rightwards, the first tension spring 15 continues to be in a stretching state, when the cable head 112 is separated from the conductive component 111, the cable head 112 is automatically moved, the circuit is in a communicating state, the occurrence of the arc phenomenon is avoided, the potential safety hazard of the circuit is reduced.
Example 2: on the basis of embodiment 1, as shown in fig. 5, the cable head further comprises a sealing assembly, the sealing assembly is arranged on the conductive assembly 111, the sealing assembly is used for sealing the conductive assembly 111 and the cable head 112, the sealing assembly comprises two sealing rings 202 which are distributed in a bilateral symmetry manner, the conductive assembly 111 is provided with two annular grooves which are distributed in a bilateral symmetry manner, the sealing rings 202 are respectively arranged in the annular grooves of the adjacent conductive assemblies 111, and a convex ring 201 matched with the adjacent sealing rings 202 is arranged on one side, close to the conductive assembly 111, of the connecting lantern ring 2.
In the process that the connecting lantern ring 2 moves rightwards, the convex ring 201 of the connecting lantern ring 2 is clamped into the annular groove of the conductive component 111 and extrudes the sealing ring 202, the sealing ring 202 deforms after extrusion, the tightness between the cable core 1121 and the conductive component 111 is improved, and external impurities are prevented from entering the connecting lantern ring, so that the normal operation of the cable core 1121 is influenced.
