Column is mounted on electromagnet armature upper surface, pressure spring set on electromagnet armature, and electromagnet armature can electromagnet with
It can be moved between vertical plate, dynamic touch panel is mounted on column top, and two static contacts are separately mounted on vertical plate top, limit switch installation
In vertical plate bottom side, edge can be with two gold of limit switch when electromagnet armature is moved downwardly to the limit, and on electromagnet armature
Belong to swing rod contact.
The utility model further includes guide plate, is oriented to sleeve-board on column.
The utility model further includes vibration damping sheet, and electromagnet is mounted on bottom plate by vibration damping sheet.
The static contact and dynamic touch panel are all made of Wu's copper and are made, and electroplate.

Specific embodiment
It is described in further detail below in conjunction with attached drawing to the embodiments of the present invention.
As shown in Figure 1, a kind of high-voltage large current relay, including bottom plate 1, electromagnet 2, electromagnet armature 3, pressure bullet
Spring 4, vertical plate 5, column 6, dynamic touch panel 7, two static contacts 8, guide plate 9, vibration damping sheet 10, limit switches 11, it is characterised in that: electricity
Magnet 2 is mounted on bottom plate 1 by vibration damping sheet 10, and vertical plate 5 is mounted on electromagnet 2, and column 6 is mounted on electromagnet armature 3
Surface, 4 sets of compression spring on electromagnet armature 3, and electromagnet armature 3 can be transported up and down between electromagnet 2 and vertical plate 5
Dynamic, dynamic touch panel 7 is mounted on the top of column 6, and two static contacts 8 are separately mounted on the top of vertical plate 5,9 sets of guide plate on column 6,
Limit switch 11 is mounted on 5 bottom side of vertical plate, when electromagnet armature 3 is moved downwardly to the limit, and along can be on electromagnet armature 3
Two metal swing rods of limit switch 11 contact.The dynamic touch panel 7 and static contact 8 of the utility model are made using Wu's copper, and
Electroplate.The utility model compression spring material is piano wire.The vertical plate is made using FR4 insulating epoxy plate.
The utility model is powered in electromagnet 2 and generates magnetic force, and electromagnet armature 3 can be moved downward because of magnetic force, compression spring 4
Compression, moves touch panel 7 and stationary contact 8 disconnects.
The utility model electromagnet 2 power off magnetic force disappear, electromagnet armature 3 can due to compression spring 4 releases stress to
Upper movement, moves touch panel 7 and stationary contact 8 is closed.
As shown in Figure 1, vibration damping sheet 10 is to reduce the impact force generated when electromagnet armature 3 moves downward.Guide plate 9
