Description

Technical Field

[0001] The invention relates to the technical field of power electronics, in particular to an inverter detection device. Background Art

[0002] An inverter is a power electronic device whose main function is to convert direct current into alternating current. The inverter realizes the conversion from direct current to alternating current, so that electric energy can meet different power needs in a suitable form. In the overload state, the total power of the power equipment connected to the inverter exceeds its rated power. At this time, the power switch tube and other electronic components inside the inverter need to carry a larger current. The long-term high current will increase the heating of the components and may cause the insulation layer of the line to degrade due to overheating and other reasons. Once the insulation is damaged, the current may form a discharge channel in a place where it should not be conducted, and the air is ionized by breakdown, thereby generating an arc. A detector is usually installed inside the inverter. Once an arc occurs, the detector will sound an alarm. After receiving the alarm, the staff will first disconnect the plug and socket, and then reasonably reduce the current output power. After the power is reduced to the right level, reconnect the plug and socket, and then continue to observe the operating status of the equipment and load to ensure normal operation. Arcs are easily generated at the moment of plugging and unplugging, especially when the equipment is plugged and unplugged when it is powered on. The sudden change of current will form an arc between the plug and socket, which will impact the internal circuit of the equipment on the one hand, and on the other hand, the high temperature generated by the arc may burn the operator, bringing safety risks.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0033] Reference Figure 2~Figure 13 , which is the first embodiment of the present invention, provides an inverter detection device, which includes a fixing component 200, a trigger component 300 and a main component 100. The three can cooperate to automatically disconnect the plug and the socket after detecting the generation of an arc, and automatically connect after adjusting the power output power to normal, without manual plugging and unplugging, which not only reduces the risk of electric shock for workers, but also can cut off the circuit in time to avoid accidents such as fire caused by untimely manual plugging and unplugging.

[0034] The fixing assembly 200 includes a plug 101, on which a fixing part 201 is arranged, on which a clamping frame 201a is arranged, a hinged rod 201b is arranged on the top of the clamping frame 201a, the clamping frame 201a and the hinged rod 201b are hinged, a movable plate 201c is hinged at one end of the hinged rod 201b, a ramp rod 201d is fixed to one side of the movable plate 201c, a ramp block 201e is arranged on one side of the ramp rod 201d, a pull rod 201f is fixed to one side of the ramp block 201e, and a cam 201g is arranged on one side of the pull rod 201f.

[0035] When the plug 101 is connected to the inverter body 102, the movable plate 201c can be squeezed. At this time, the movable plate 201c can drive the hinge rod 201b to move, and the movement of the hinge rod 201b can drive the clamping frame 201a to move. A support block is provided at the bottom of the clamping frame 201a, and a support column is sleeved on the outer side of the support block. The support block and the support column are slidably connected, and the support column is fixed to one side of the inverter body 102. The clamping frame 201a can be supported by the setting of the support column to prevent the clamping frame 201a from deviating during movement. When the clamping frame 201a moves to contact with the plug 101, the plug 101 can be fixed to prevent the plug 101 from separating from the inverter body 102. When the movable plate 201c moves, the inclined rod 201d can be driven to move. A connecting groove corresponding to the inclined block 201e is provided on one side of the inclined rod 201d. A connecting tube is sleeved on the outer side of the rod 201d, and the connecting tube is fixed to the inner wall of the inverter body 102. The inclined rod 201d and the connecting tube are movably connected. The connecting tube is used to support the inclined rod 201d, and a connecting spring is fixed on one side of the movable plate 201c. The movable plate 201c can exert an extrusion force on the connecting spring when it moves. In order to prevent the rebound force of the connecting spring from driving the movable plate 201c to return to its original position, the movable plate 201c can be limited by the engagement of the inclined block 201e with the connecting groove. When it is necessary to release the limit on the movable plate 201c and return it to its original position, the cam 201g is rotated, and the convex surface of the cam 201g squeezes the pull rod 201f to make it move. The pull rod 201f moves and drives the inclined block 201e to separate from the connecting groove, thereby releasing the limit on the movable plate 201c, and then the movable plate 201c is driven to return to its original position by the rebound force of the connecting spring.

[0036] The trigger assembly 300 is arranged on one side of the fixing member 201, and includes a trigger member 301. A magnetic wire reel 301a is arranged on the trigger member 301. An armature 301b is inserted on the top of the magnetic wire reel 301a. A guide plate 301c is fixed to one side of the armature 301b. A protrusion 301d is arranged on one side of the guide plate 301c. A slider 301e is fixed to one end of the protrusion 301d. A slide bar 301f is fixed to the bottom of the slider 301e. A hinge bar 301g is arranged at one end of the slide bar 301f. The hinge bar 301g and the slide bar 301f are hinged. An extrusion rod 301h is sleeved on the outer side of the hinge bar 301g. The extrusion rod 301h and the hinge bar 301g are movably connected. A guide rod 301i is arranged on one side of the extrusion rod 301h. A drive rod 301j is hinged to one end of the guide rod 301i. The drive rod 301j is arranged on one side of the plug 101.

[0037] When the arc detector 302c detects the generation of an arc, an alarm will be sounded to alert the staff, and then the armature 301b will move. When the armature 301b moves, it will drive the guide plate 301c to descend, releasing the squeeze on the protrusion 301d, and the slider 301e will move at this time. When the slider 301e moves, it will drive the slide bar 301f to move. When the slide bar 301f moves, it will drive the hinged bar 301g to move. The movement of the hinged bar 301g will drive the squeezing rod 301h to move. When the slider 301e moves, it will drive the squeezing rod 301h to squeeze the guide rod 301i. At this time, the hinged bar 301g will flip and will not drive the guide rod 301i to move. When the slider 301e moves, the cam 201g will be driven to rotate to separate the clamping frame 201a from the plug 101. At this time, the circuit will be disconnected. When the circuit returns to normal, the armature 301b will return to its original position. At this time, the guide plate 301c can be driven to move, so that the guide plate 301c squeezes the protrusion 301d to drive the slider 301e to return to its original position. When the slider 301e returns to its original position, it will drive the squeezing rod 301h to squeeze the reverse guide rod 301i. At this time, the guide rod 301i can be moved, and the guide rod 301i drives the driving rod 301j to move. Through the movement of the driving rod 301j, the plug 101 can be reconnected with the inverter body 102.

[0038] The guide rod 301i is hinged to the inner wall of the inverter body 102, and a return torsion spring is fixed on one side of the guide rod 301i. The torsion force of the return torsion spring can support the guide rod 301i. Example 2

[0039] Reference Figure 2~Figure 13 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0040] Specifically, the fixing assembly 200 also includes a support member 202, which is arranged on the plug 101, an insertion rod 202a is fixed at the bottom of the plug 101, a support sleeve 202b is sleeved on the outer side of the insertion rod 202a, the insertion rod 202a and the support sleeve 202b are movably connected, a first spring 202c is arranged at one end of the insertion rod 202a, the first spring 202c is fixed to the inner wall of the support sleeve 202b, a movable block 202d is fixed at the top of the plug 101, a movable rod 202e is arranged on one side of the movable block 202d, and the movable rod 202e is fixed to the top of the movable plate 201c.

[0041] When the plug 101 is connected to the inverter body 102, the plug rod 202a can be driven to move in the support sleeve 202b. The support sleeve 202b is fixed to one side of the inverter body 102, and the plug rod 202a can apply a squeezing force to the first spring 202c when it moves. When the clamping frame 201a is separated from the plug 101, the limit on the plug 101 is released, and the rebound force of the first spring 202c can drive the plug 101 to separate from the inverter body 102.

[0042] The movement of the plug 101 drives the movable block 202d to move, and the movement of the movable block 202d squeezes the movable rod 202e. The movement of the movable rod 202e drives the movable plate 201c to move, and the movement of the movable plate 201c drives the clamping frame 201a to engage with the plug 101.

[0043] Specifically, a second spring 202f is fixed on one side of the inclined block 201e, and the second spring 202f is fixed to the inner wall of the inclined rod 201d. The pull rod 201f is inserted into one side of the inclined rod 201d, and the pull rod 201f and the inclined rod 201d are movably connected. A rotating column 202g is fixed on one side of the cam 201g, and a driving disk 202h is inserted at one end of the rotating column 202g. An inclined panel 202i is provided on one side of the driving disk 202h, and a third spring 202j is fixed on the top of the inclined panel 202i. A support disk 202k is sleeved on the outer side of the inclined panel 202i, and the support disk 202k and the inclined panel 202i are movably connected. A rotating rod 202l is provided on one side of the driving disk 202h, and a tension spring 202m is fixed on one side of the rotating rod 202l, and the tension spring 202m is fixed to one side of the driving disk 202h.

[0044] When the pull rod 201f moves, it will drive the inclined surface block 201e to move. At this time, the movement of the inclined surface block 201e can apply a squeezing force to the second spring 202f. When the convex surface of the cam 201g rotates to separate from the pull rod 201f, the rebound force of the second spring 202f can drive the inclined surface block 201e to return to its original position.

[0045] A positioning groove corresponding to the inclined plate 202i is provided on one side of the driving disk 202h. When the inclined plate 202i rotates, it will first apply a pulling force to the tension spring 202m. At this time, the driving disk 202h will not rotate due to the engagement of the inclined plate 202i with the positioning groove. When the rotating rod 202l rotates to contact the inclined plate 202i, it can squeeze it. When the inclined plate 202i moves, it can apply a squeezing force to the third spring 202j. The inclined plate 202i moves and separates from the positioning groove to release the limit of the driving disk 202h. Then, the pulling force of the tension spring 202m rebounding can drive the driving disk 202h to rotate. When the driving disk 202h rotates, it will drive the positioning groove to engage with the next inclined plate 202i. The rebound force of the third spring 202j can drive the inclined plate 202i to move and engage with the positioning groove. In this way, the reciprocating movement can drive the rotating column 202g to rotate, and the rotation of the rotating column 202g can drive the cam 201g to rotate.

[0046] Specifically, the fixing assembly 200 also includes a rotating member 203, which is arranged on a rotating column 202g, a rotating shell 203a is fixed at one end of the rotating column 202g, a clamping block 203b is arranged in the rotating shell 203a, a connecting disk 203c is sleeved on the outer side of the clamping block 203b, the clamping block 203b and the connecting disk 203c are hinged, a first torsion spring 203d is fixed on one side of the clamping block 203b, the first torsion spring 203d is fixed to the inner wall of the connecting disk 203c, a reel 203e is fixed on one side of the connecting disk 203c, a coil spring 203f is fixed on one side of the reel 203e, a positioning shell 203g is sleeved on the outer side of the coil spring 203f, a pull rope 203h is arranged in the reel 203e, a fixed pulley 203i is arranged on one side of the pull rope 203h, and one end of the pull rope 203h is fixed to the top of the slider 301e.

[0047] A card slot corresponding to the card block 203b is provided in the rotating shell 203a. When the slider 301e moves, the pull rope 203h can be driven to move. When the pull rope 203h moves, the reel 203e can be driven to rotate. When the reel 203e rotates, a torsional force can be applied to the coil spring 203f. The positioning shell 203g is fixed to the inner wall of the inverter body 102. The coil spring 203f can be supported by the setting of the positioning shell 203g. The rotation of the reel 203e will drive the connecting disk 203c to rotate. The rotation of the connecting disk 203c can drive the card block 203b to rotate. The rotation of the card block 203b can squeeze the card slot to rotate the rotating shell 203a. The rotation of the rotating shell 203a can drive the rotating rod 202l to rotate. The rotating rod 202l is fixed to one side of the rotating shell 203a. The rotating shell 203a is rotatably connected to the driving disk 202h through a rotating shaft.

[0048] When the slider 301e returns to its original position, the pulling of the pull rope 203h can be released. At this time, the force of the rotation of the coil spring 203f can drive the connecting disk 203c to reverse, and then drive the block 203b to reverse. At this time, the slot can squeeze the block 203b to make it move. When the block 203b moves, it can apply a torsional force to the first torsion spring 203d. When the slot rotates to re-engage with the block 203b, the force of the rotation of the first torsion spring 203d can drive the block 203b to return to its original position. In this reciprocating manner, when the slider 301e returns to its original position, it will not drive the cam 201g to rotate.

[0049] Specifically, the trigger assembly 300 also includes a movable part 302, which is arranged on the armature 301b. A reset spring 302a is fixed to the bottom of the armature 301b, a support frame 302b is fixed to the bottom of the reset spring 302a, the magnetic wire drum 301a is fixed to the top of the support frame 302b, and an arc detector 302c is arranged on one side of the magnetic wire drum 301a.

[0050] When the armature 301b moves, it can apply a squeezing force to the reset spring 302a. When the current returns to normal, the rebound force of the reset spring 302a can drive the armature 301b to return to its original position. The magnetic wire drum 301a is used to support the armature 301b. The support frame 302b is fixed to the inner wall of the inverter body 102. The magnetic wire drum 301a can be supported by the setting of the support frame 302b. When the arc detector 302c detects an arc, it relies on sensing the characteristic signals such as the sudden change of current and abnormal voltage generated by the arc. Once the signal meets the preset conditions, it is determined that an arc has occurred, and then the internal circuit is used to trigger the sound and light alarm module to sound an alarm, and at the same time, an electrical signal is output to drive the electromagnetic device to move the armature 301b. The arc detector 302c belongs to the prior art and will not be elaborated here.

[0051] Specifically, a positioning frame 302d is sleeved on the outer side of the slider 301e, the positioning frame 302d and the slider 301e are slidably connected, a connecting frame 302e is fixed to one side of the positioning frame 302d, a limiting frame 302f is set in the connecting frame 302e, and a limiting strip 302g is set on the top of the limiting frame 302f.

[0052] The positioning frame 302d is fixed to the inner wall of the inverter body 102. The positioning frame 302d can support the slider 301e. A fixing groove corresponding to the limiting strip 302g is provided on the limiting frame 302f. When the slider 301e moves, the limiting strip 302g can be driven to slide on the limiting frame 302f. The setting of the fixing groove can prevent the limiting strip 302g from returning to its original position. Then, the movement of the slider 301e will drive the limiting strip 302g to move into the sliding groove in the connecting frame 302e. At this time, the limiting strip 302g will drive the slider 301e to return to its original position, and then drive the guide plate 301c to return to its original position through the armature 301b. The guide plate 301c squeezes the protrusion 301d to make it move, and the movement of the protrusion 301d can drive the slider 301e to return to its original position. Example 3

[0053] Reference Figure 1 to Figure 13 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0054] Specifically, a connecting sleeve 302h is provided on the outer side of the limit bar 302g, and the connecting sleeve 302h and the limit bar 302g are movably connected. A fourth spring 302n is fixed on the top of the limit bar 302g, and the fourth spring 302n is fixed to the inner wall of the connecting sleeve 302h. A translation bar 302i is fixed on the top of the connecting sleeve 302h, and a positioning column 302j is inserted on one side of the translation bar 302i. The positioning column 302j and the translation bar 302i are movably connected, and the positioning column 302j is fixed to one side of the slider 301e.

[0055] When the limit bar 302g moves, the connection sleeve 302h can support the limit bar 302g. When the limit bar 302g moves to separate from the fixed groove, the fourth spring 302n can apply an extrusion force. When the limit bar 302g moves to the top of the fixed groove, the fourth spring 302n can rebound and drive the limit bar 302g to re-engage with the fixed groove. An extrusion block is provided at one end of the slide groove on the connection frame 302e, and the protrusion 302n is provided. 1d can drive the slider 301e to return to its original position, and the limit bar 302g can be squeezed and moved into the limit frame 302f through the setting of the extrusion block, and then the translation bar 302i can be squeezed.

When the limit bar 302g moves to separate from the limit frame 302f, the rebound force of the fifth spring 303c can drive the translation bar 302i to rebound.

[0058] Specifically, a sliding plate 303d is fixed to the bottom of the sliding block 301e, a sixth spring 303e is fixed to one side of the sliding plate 303d, and a support tube 303f is fixed to one end of the sixth spring 303e.

[0059] The support tube 303f is fixed to one side of the inverter body 102. When the slider 301e is in the initial position, it will apply a squeezing force to the sixth spring 303e. At this time, the slider 301e can be limited by squeezing the protrusion 301d by the guide plate 301c. When the guide plate 301c moves to release the squeezing of the protrusion 301d, the limitation of the slider 301e can be released, and then the slider 301e can be driven to move by the rebound force of the sixth spring 303e. The sixth spring 303e can be supported by the setting of the support tube 303f.

[0060] Specifically, it also includes a main body component 100, which is arranged on a plug 101, an inverter body 102 is arranged on one side of the plug 101, a pressing plate 103 is arranged on one side of the plug 101, and a driving rod 301j is sleeved on the outer side of the pressing plate 103.

[0061] A leakage groove is provided on the driving rod 301j, and a fixing block is fixed on one side of the pressing plate 103.

A supporting spring is fixed at the bottom of the pressing plate 103, and the supporting spring is fixed to the inner wall of the plug 101. When it is necessary to completely separate the plug 101 from the inverter body 102, the pressing plate 103 is squeezed, and a squeezing force can be applied to the supporting spring at this time, and then the fixing block will be separated from the leakage groove, so that the plug 101 can be separated from the inverter body 102, and then the pressing plate 103 is released, and the rebound force of the supporting spring can drive the pressing plate 103 to return to its original position for next use, and the inverter body 102 can convert DC power into AC power, thereby realizing the conversion of DC power to AC power.

[0062] When in use, first, align the plug 101 with the inverter body 102 to prepare for connection. During the connection process, the plug 101 will drive the bottom plug rod 202a to move in the support sleeve 202b. When the plug rod 202a moves, it will apply a squeezing force to the first spring 202c fixed to the inner wall of the support sleeve 202b. At the same time, the movement of the plug 101 will also drive the top movable block 202d to move. The movement of the movable block 202d will squeeze the movable rod 202e. The movement of the movable rod 202e will then drive the movable plate 201c to move. When the movable plate 201c moves, on the one hand, it will apply a squeezing force to the connecting spring fixed on one side thereof, and on the other hand, it will drive the inclined rod 201d to move. The inclined rod 201d moves stably under the support of the connecting pipe that is sleeved on the outside and fixed to the inner wall of the inverter body 102. The movement of the surface rod 201d drives the inclined block 201e that cooperates with it through the connecting groove to move. The movement of the inclined block 201e will apply a squeezing force to the second spring 202f fixed on one side of it. At the same time, the movement of the movable plate 201c drives the hinged rod 201b to move. The movement of the hinged rod 201b drives the clamping frame 201a hinged to it to move. The clamping frame 201a is sleeved at its bottom and moves under the support of the support column fixed on one side of the inverter body 102. When the clamping frame 201a moves to contact the plug 101, the plug 101 can be fixed to prevent the plug 101 from separating from the inverter body 102. The inclined block 201e is engaged with the connecting groove on the inclined rod 201d, which can limit the movable plate 201c and prevent the connecting spring from rebounding and driving the movable plate 201c to return to its original position.

[0063] Next, when the arc detector 302c detects the occurrence of an arc, it will sound an alarm to remind the staff, and at the same time the armature 301b will move, and the movement of the armature 301b drives the guide plate 301c to descend, releasing the squeezing of the protrusion 301d, and the slider 301e fixed at one end of the protrusion 301d slides in the positioning frame 302d. The positioning frame 302d is fixed to the inner wall of the inverter body 102 to support the slider 301e. The movement of the slider 301e drives the sliding rod 301f to move, and the movement of the sliding rod 301f drives the hinged bar 301g hinged thereto to move, and the movement of the hinged bar 301g drives the squeezing When the rod 301h moves, the movement of the slider 301e will also drive the extrusion rod 301h to squeeze the guide rod 301i. At this time, the hinge strip 301g will flip and no longer drive the guide rod 301i to move, and the movement of the slider 301e will drive the cam 201g to rotate. The rotation of the cam 201g is achieved by a rotating column 202g fixed on one side of it. The inclined plate 202i on the driving disk 202h plugged into one end of the rotating column 202g first applies a pulling force to the tension spring 202m during the rotation process, and the inclined plate 202i engages with the corresponding positioning groove on the driving disk 202h to make the driving disk 202h Do not rotate temporarily, when the rotating rod 202l rotates to contact the inclined plate 202i, it is squeezed, the inclined plate 202i moves to apply squeezing force to the third spring 202j and separate from the positioning groove, thereby releasing the limit on the driving plate 202h, and the tension spring 202m rebounds to drive the driving plate 202h to rotate, and the driving plate 202h rotates to drive the positioning groove to engage with the next inclined plate 202i, and the third spring 202j rebounds to drive the inclined plate 202i to move and engage with the positioning groove, and the rotating column 202g is rotated reciprocatingly, and the rotation of the rotating column 202g drives the cam 201g to rotate, and the rotation of the cam 201g makes The clamping frame 201a is separated from the plug 101, and the circuit is disconnected at this time. The movement of the slider 301e also drives the pull rope 203h to move. The movement of the pull rope 203h drives the reel 203e to rotate. The rotation of the reel 203e applies a torsional force to the coil spring 203f. The rotation of the reel 203e drives the connecting disk 203c to rotate. The rotation of the connecting disk 203c drives the block 203b to rotate. The rotation of the block 203b squeezes the corresponding slot in the rotating shell 203a to rotate the rotating shell 203a. The rotation of the rotating shell 203a drives the rotating rod 202l to rotate, further assisting the above-mentioned related actions.

[0064] When the circuit returns to normal, the armature 301b returns to its original position under the rebound force of the return spring 302a. When the armature 301b moves, it exerts a squeezing force on the return spring 302a. The bottom of the return spring 302a is fixed on the support frame 302b, and the support frame 302b is fixed to the inner wall of the inverter body 102. The magnetic wire cylinder 301a is fixed on the top of the support frame 302b to support the armature 301b. The armature 301b returns to its original position and drives the guide plate 301c to move. The guide plate 301c squeezes the protrusion 301d to drive the slider 301d. 01e returns to its original position. When the slider 301e returns to its original position, on the one hand, it will drive the pull rope 203h to release the pulling, and the rotation force of the coil spring 203f will drive the connecting disk 203c to reverse, and then drive the block 203b to reverse, and the slot squeezes the block 203b to make it move. The movement of the block 203b applies a torsional force to the first torsion spring 203d. When the slot rotates to re-engage with the block 203b, the rotation force of the first torsion spring 203d drives the block 203b to return to its original position, so that when the slider 301e returns to its original position, it will not drive the cam 201g to rotate.

[0065] On the other hand, the slider 301e returns to its original position and drives the limit bar 302g to move. When the limit bar 302g moves, it is supported by the connecting sleeve 302h sleeved on the outside, and when it moves to separate from the fixed groove on the limit frame 302f, it applies an extrusion force to the fourth spring 302n. When the limit bar 302g moves to the top of the fixed groove, the fourth spring 302n rebounds and drives the limit bar 302g to re-engage with the fixed groove. The extrusion block at one end of the slide groove on the connecting frame 302e can squeeze the limit bar 302g to move it into the limit frame 302f, and then the translation bar 302 i is squeezed, and when the limit bar 302g moves to separate from the limit frame 302f, the translation bar 302i is squeezed by the extrusion plate 303b fixed at one end of the fifth spring 303c translation bar 302i, and the fifth spring 303c is fixed to the support plate 303a fixed at the bottom of the slider 301e under the action of the rebound force, driving the limit bar 302g to move into the sliding groove on the connecting frame 302e.

Before the guide plate 301c squeezes the protrusion 301d to limit the slider 301e again, the slider 301e returns to its original position and drives the squeezing rod 301h to squeeze the reverse guide rod 301i, so that the guide rod 301i moves, and the guide rod 301i drives the driving rod 301j hinged therewith and sleeved on the outside of the pressing plate 103 to move. A fixing block is fixed on one side of the pressing plate 103, and a leakage groove is provided on the driving rod 301j, which is connected When the plug 101 is connected to the inverter body 102, the fixing block is engaged with the leakage groove, and a supporting spring is fixed at the bottom of the pressing plate 103. The supporting spring is fixed to the inner wall of the plug 101, and the plug 101 is driven to reconnect with the inverter body 102 by the movement of the driving rod 301j. If the plug 101 is to be completely separated from the inverter body 102, the pressing plate 103 can be squeezed to apply squeezing force to the supporting spring to separate the fixing block from the leakage groove, and the plug 101 can be separated from the inverter body 102. After releasing the pressing plate 103, the supporting spring rebounds and drives the pressing plate 103 to return to its original position for next use.
