Plate or other fixtures, one end of back-moving spring 8 is against fixed part 9, and the other end of back-moving spring 8 is then against iron core 7.
When relay is in release conditions, movable contact spring 2 is in phase-separated state, contact with the stationary contact 8 in relay
Slide block 3 is pushed up the first limiting section 11 to catch bar by movable contact spring 2 by stage clip 5, and fine motion is not opened by the arm 31 of stirring of slide block 3
The swing arm 41 of pass 4 works.
During action, coil 6 works, and iron core 7 is drawn to static iron core or yoke, and iron core drives catch bar 1 to move up, catch bar
1 drives movable contact spring 2, slide block 3 to move up by contact stage clip 5, slide block 3 stir the arm 31 swing arm to microswitch 4
41 work, and the swing arm 41 of microswitch 4 performs the stroke of microswitch, when movable contact spring 2 connects with the stationary contact 8 in relay
When touching, the swing arm 41 of microswitch 4 also completes the stroke of microswitch (being equivalent to auxiliary contact also contact), now, direct acting
The magnetic gap stroke of formula magnetic circuit not yet completes, and catch bar 1 continues to move up (i.e. overtravel), and catch bar 1 is by contact stage clip 5
There is provided the contact pressure of movable contact spring 2 and stationary contact 8, now, owing to the arm 31 of stirring of slide block 3 is complete the row of microswitch
Journey, slide block 3 can not move up, then, when catch bar 1 continues to move up, the space that slide block 3 utilizes gap S to be provided is returned
Move back, do not interfere with catch bar 1 and complete magnetic gap stroke.
When relay is in operating state, movable contact spring 2 is in the state of contacting, fine motion with the stationary contact 8 in relay
Switching 4 in the conduction state, slide block 3 is against the second limiting section 12, certainly, according to design needs, it is also possible to be proximate to second
Limiting section 12.
During release, back-moving spring 8 works, and makes catch bar 1 move down, and when catch bar 1 moves down, utilizes contact to press
Spring 5, pushes up again the first limiting section 11 to catch bar by movable contact spring 2 by slide block 3, after catch bar 1 moves down, drives dynamic touching
Sheet 2 and slide block 3 move down, and movable contact spring 2 moves down and makes movable contact spring 2 be separated with stationary contact 8, and slide block 3 makes the swing arm of microswitch 4
41 reset, and microswitch 4 also disconnects.
The HVDC relay of a kind of band microswitch of the present invention, have employed and slide block 3 is arranged on catch bar 1
On, and be reserved with in the installation place of slide block 3 can be movable gap S, when the actuating of relay, slide block 3 is with catch bar 1
Mobile and move, when when slide block 3 completes the stroke of microswitch 4, catch bar 1 continues to move along, slide block 3 can be in order to
With default gap rollback, this structure, on the one hand it is possible to prevent slide block excessive and cause fine motion to open to the power of microswitch
The damage closed, on the other hand can eliminate the slide block impact on movable contact spring stroke so that during the actuating of relay, movable contact spring is with quiet
Contact is more reliable.
