Working principle and using flow:
firstly, a worker can plug the wiring male head 3 and the wiring female head 2, meanwhile, the mounting strip 18 drives the ratchet 10 to rotate along the outer side of the cylinder 9 through the cooperation between the mounting strip 18 and the ratchet 10, when the electromagnet 16 is in an electrified state, magnetism is generated, meanwhile, the electromagnet 16 and the magnetic block 15 repel each other, the movable block 12 drives the pawl 14 to be clamped with the ratchet 10, the ratchet 10 only rotates in a single direction through the cooperation between the pawl 14 and the ratchet 10, the mounting strip 18 can be limited, the mounting strip 18 is prevented from backing, the loosening of the wiring hole 4 and the wiring post 5 is avoided, after the electromagnet 16 is powered off, the first spring 13 can apply an elastic force to the movable block 12, so that the pawl 14 and the ratchet 10 are driven to be separated, the locking state of the ratchet 10 to the mounting strip 18 can be relieved, the ratchet 10 is driven to rotate and reset through the round shaft 31, the wiring male head 3 and the female head 2 can be driven to be separated through the mounting strip 18, and the wiring male head 3 can be automatically pulled out when a fault occurs;
when the staff overhauls the ammeter, and one wiring male head 3 needs to be pulled out from the lower part of the wiring female head 2, the process of pulling out the wiring male head 3 is as follows:
in the first step, in the position state shown in fig. 2 (i.e., fig. 2 of the specification), the pressure point of application when pressing the second mounting plate 29 is located at the right end of the second mounting plate 29, that is, when pressing, the second mounting plate 29 is laterally pressed from the right end of the second mounting plate 29, so that the second mounting plate 29 slides from the right side to the left side in the figure. After the second mounting plate 29 is pressed to slide, the movable plate 22 fixedly connected to the upper side of the second mounting plate 29 slides left along with the second mounting plate from the right side in fig. 2 of the specification, the movable plate 22 slides to drive the round rod 23 connected to the second mounting plate to slide, and after the round rod 23 slides, the tail end of the round rod 23 is inserted into the round groove 27 on the movable frame 26, and then the movable frame 26 is pushed leftwards, so that the clamping between the movable frame 26 and the clamping groove 28 fails, namely the movable frame 26 is separated from the clamping groove 28.
Step two, under the condition that the second mounting plate 29 is continuously pressed, the wiring male head 3 is pulled towards the direction away from the wiring female head 2, in the process that the wiring male head 3 is pulled out, the movable plate 22 arranged on the wiring male head 3 drives the round rod 23 arranged on the movable plate 23 to be away from the wiring female head 2 downwards, the movable plate 22 is capable of pulling the movable frame 26 downwards through the cooperation of the round rod 23 and the round groove 27 (at the moment, the movable frame 26 is separated from the clamping groove 28), and the first mounting plate 8 is also pulled by the movable plate 22 due to the fact that the movable frame 26 is connected to the first mounting plate 8, and is further away from the wiring female head 2 downwards together with the movable plate 22, the round rod 23 and the movable frame 26. Because the first mounting plate 8 is connected through the sliding fit between the movable rod 7 and the connecting plate 6 (the lower end of the movable rod 7 is connected to the first mounting plate 8), the first mounting plate 8 can translate downwards after being pulled, so that the ratchet 10 and the pawl 14 connected to the first mounting plate 8 are separated, the ratchet 10 can rotate, and the blocking effect of the ratchet 10 and the pawl 14 on the pulling-out of the wiring male 3 is avoided. Through such design, under the condition that the electromagnet 16 is not powered off, a certain wiring male head 3 can be detached independently still through a mode of pressing the mounting plate II 29 and then applying a pulling force to the wiring male head 3. "
Step three, after the ratchet 10 is separated from the pawl 14, the pressing of the second mounting plate 29 is stopped, so that the second mounting plate 29 and the movable plate 22 are reset rightward under the action of the elastic force of the second spring 21 (refer to the positional relationship shown in fig. 2 of the specification), after the reset, the round rod 23 is separated from the round groove 27, and after the separation, the movable frame 26 is no longer subjected to the force from the round rod 23, so that the movable frame 26, the first mounting plate 8 and the movable rod 7 are reset upward under the action of the elastic force of the reset spring 32.
