And 104, implanting the positioning device 30 into the second connecting device 20, wherein when the positioning device 30 is implanted into the second connecting device 20 to the second implantation state, the positioning device 30 is locked with the second connecting device 20.
In this step, the head 3011 is engaged with a recess formed on the upper surface of the buckle 2022, the second boss 3013 is engaged with the slot 2023, and the end of the rocker structure 201 is clamped between the implantation structure 301 and the blocking structure 302.
In addition, as shown in fig. 11, based on the connector for preventing live plugging and unplugging according to the embodiment of the present invention, the embodiment of the present invention further discloses an unlocking method for a connector for preventing live plugging and unplugging, including the following steps:
in this step, the head 3011 is lifted above the first positioning structure 101 and the buckle 2022;
in this embodiment, before the positioning device 30 is pulled out of the second connecting device 20 to the first implantation state, the limiting protrusion 203 can limit the downward movement amplitude of the positioning device 30, and the positioning device 30 cannot be unlocked by pressing, so that unlocking caused by mistakenly pressing the positioning device 30 can be effectively prevented;
meanwhile, before the positioning device 30 is pulled out of the second connecting device 20 to the first implantation state, the tail end of the rocker structure 201 is clamped between the implantation structure 301 and the blocking structure 302, so that the up-and-down movement amplitude of the rocker structure 201 can be greatly limited, and therefore, when the positioning device 30 is implanted into the second connecting device 20 to the second implantation state, the unlocking caused by mistakenly pressing the rocker structure 201 can be effectively prevented;
furthermore, before the positioning device 30 is pulled out of the second connecting device 20 to the first implantation state, the blocking structure 302 is structurally reinforced by the stiffener structure 303, so that the unlocking caused by too much force of mistakenly pressing the rocker structure 201 is prevented.
According to the unlocking method of the connector for preventing live plugging and unplugging, disclosed by the invention, in the unlocking process of the connector for preventing live plugging and unplugging, the signal male and female terminals are separated by unlocking the wane structure 201, then the power male and female terminals are separated by unlocking the positioning device 30, and the wane structure 201 and the positioning device 30 are respectively positioned at two sides of the connector for preventing live plugging and unplugging, so that the connector for preventing live plugging and unplugging is respectively unlocked in sections from two sides, the misoperation of simultaneous unlocking when the structure for unlocking is positioned at one side is avoided, and the safety in the operation process is further improved.
In summary, in the prior art, a high voltage arc is generated instantaneously when the male terminal and the female terminal of the power terminal are separated, which may cause a potential safety hazard of personal injury. By adopting the connector for preventing live plugging and unplugging, the positioning device in the second locking state can not be pressed, false unlocking can be prevented, meanwhile, the blocking structure in the positioning device can prevent the rocker structure from being pressed by mistake, and after the positioning device is unlocked to the first implantation state, the rocker structure is pressed to unlock the second positioning structure, so that the signal terminals are separated; and then the positioning device is pressed to unlock the first positioning structure, so that the power terminals are separated, and the connector is unlocked. In addition, because the position of the unlocking signal terminal and the position of the unlocking power terminal are respectively positioned at two sides of the connector, the problem that simultaneous unlocking can occur when the positions of the unlocking two terminals are positioned at one side can be avoided. Through the connector for preventing live plugging, the signal terminals which are interlocked can be separated first, the power terminals are separated later, and the live plugging operation of the connector is effectively avoided.
The same and similar parts in the various embodiments in this specification may be referred to each other. The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention.
