Specific embodiment
In order to be further understood that the summary of the invention of the utility model, this reality is elaborated below in conjunction with specific embodiment
With novel.
As shown in Figure 1, the utility model provides a kind of double sealing high pressure contactor, including shell 2, bottom cover 1 and contact group
Part, the bottom cover 1 are arranged in 2 lower end of shell, and the shell 2 is arranged in the contact assembly and composition is covered at the bottom 1
In enclosure space, the contact assembly is divide into upper part and lower part by upper plate 10, the contact assembly be located at the upper plate 10 with
Under part include magnetizer 3, hollow coil 4, sealing column 5, interlocking lever 9, moving magnet 6 and static magnet 8,6 He of moving magnet
The static magnet 8 is arranged one on the other, and the static magnet 8 is arranged above the moving magnet 6, the moving magnet 6 and described quiet
Reaction spring 7 is set between magnet 8, and the magnetizer 3 is arranged on the bottom cover 1, and the hollow coil 4 is arranged described
On magnetizer 3, in the hollow circle 4 of the line, the moving magnet 6 and the static magnet 8 are arranged at institute for the setting of sealing column 5
It states in sealing column 5, the part that the contact assembly is located at 10 or more the upper plate includes sealed base 11, moving contact 14, stationary contact
First 17 and ceramic seal shell 19, the sealed base 11 and the ceramic seal shell 18 connect, thus may be used by welding
To guarantee the leakproofness of the two combination, guarantee internal element from the influence of extraneous factor, internal is the sealing of accommodation space
Structure, the moving contact 14 and the static contact 17 are respectively provided with the appearance inside the sealed base 11 and the ceramic seal shell 18
It receives in space, lower gearing rod set 12 and the first line of a couplet is respectively set in the periphery that the interlocking lever 9 is located at the part of 10 or more the upper plate
Lever covers 15, and touch spring 13 is arranged in the lower gearing rod set 12, E type circlip 16 is arranged in the upper gearing rod set 15.
When the present embodiment is run, when power supply is connected, the hollow coil 4 is powered on, and the static magnet 8 generates electromagnetic attraction,
The moving magnet 6 overcomes the elastic force of the reaction spring 7, and the static magnet 8 moves；Since inside fixation is inconjunction with the gearing
Bar 9 will drive the interlocking lever 9 that the moving magnet 6 is followed to move upwards, and due to described so the moving magnet 6 moves
Moving contact 14 is mounted on the upper end of the interlocking lever 9 by upper and lower connecting rod set, the interlocking lever 9 follow the moving magnet 6 to
Also the moving contact 14 is driven to move upwards while upper movement, so that the moving contact 14 and the static contact 17 are in contact,
Contact closure, to control load.
Work as power cut-off, when hollow 4 power loss of coil, the electromagnetic attraction of the static magnet 8 disappears, by the counter-force
The reaction force of spring 7, the moving magnet 6 are separated with the static magnet 8, and the moving magnet 6 is restored to downwards original position, described quiet
8 mesoporous of magnet is less than 9 intermediate ledge of interlocking lever point, so that the moving magnet 6 reaches fixed position, while the gearing
Bar 9 moves downward, and the moving contact 14 and the static contact 17 disconnect, and contact disconnects, and stops the control to load.
When the utility model is in the circuit for high-voltage large current, the sealing of contact is simultaneously filled with inert gas, effectively
Ground reduces contactor injury caused by contact as phenomenon of arc discharge in disjunction, carries out between the head and shell of sealing
Encapsulating preferably protects the harm as brought by the rupture of the sealing ceramic case on head.
It will be apparent to those skilled in the art that the double sealing high pressure contactor of the utility model includes above-mentioned the utility model
Any combination of each section shown by the summary of the invention and specific embodiment part and attached drawing of specification, as space is limited simultaneously
Each scheme to keep specification concise without constituting these combinations describes one by one.It is all in the spirit and principles of the utility model
