This points out that connecting rod 30 can also use the linkage of other structures to substitute.
In conjunction with Fig. 1-4, operation principle of the invention is briefly described.
Referring to Fig. 1 and 3, closing course：Active contact supporting 11 and active contact 15 are under external force F effects around active contact
Rotating shaft 13 is rotated in an anti-clockwise direction, and active contact assembly underarm 152,112 is promoted from moving contact rack 21 around from moving contact simultaneously
Rotating shaft 23 is rotationally clockwise so that active contact 15 and is moved towards each other from moving contact 24, thus Rapid contact.Herein
In transport process, active contact supporting reduction torsion spring 12 and enough torsion is laid in from moving contact torsion spring 9.Due to active contact
Excess of stroke torsion spring 14 is provided between 15 and active contact supporting 11, when active contact 15 and after contacted from moving contact 24, is actively touched
Head bracket 11 may proceed to rotate, and cross the dead point of actuating mechanism, and now it is suitable to continue around the rotating shaft 13 of active contact for active contact 15
Clockwise rotates, and have compressed journey torsion spring 14, active contact 15 is ensured the contact between it to producing pressure from moving contact 24
Reliably.
Referring to Fig. 2 and 4, process is switched off：When manually operated is cut-off, or short circuit, overload protection arrangement starts makes
When obtaining the disconnection of switch motion mechanism, active contact supporting 11 and active contact 15 act in active contact supporting reduction torsion spring 12
Under, active contact supporting 11 and active contact 15 are rotated in the clockwise direction, while are answered from moving contact rack 21 from moving contact
Rotated in the counterclockwise direction in the presence of the torsion spring 22 of position so that active contact 15 and from 24 motion opposite each other of moving contact, thus
Quick disconnecting circuit.Because active contact 15 and moving simultaneously in opposite directions when being disconnected from moving contact 24, responsiveness
It is 2 times of existing dynamic/static contact system acting speed, the space length of two contacts quickly increases, and arc diameter rapidly diminishes, and goes out
Arc becomes to be more prone to.
Present invention also offers a kind of switch disconnector, wherein, the switch disconnector includes base and installed in base
