Description
Technical field
The present invention relates to a kind of high pressure sealing D.C. contactor with auxiliary contact, fine motion in replacement seal D.C. contactor
Switch makees the function of auxiliary contact.
Background technology
(or disconnect) is used, it is necessary to a kind of connection of auxiliary contact when the main contacts of seal DC contactor is switched on or switched off
Judge in main contacts state, judgement operation is done to main contacts state by this auxiliary contact, when being actually used for improving product
Security.In actual application, auxiliary contact break-make low current, play the break-make of signal.At present, due to sealing
The problem of with design, the seal DC contactor of in the market is typically without auxiliary contact, the sealed direct-current contact with auxiliary contact
The auxiliary contact of device typically using microswitch is set in arc-chutes, connect plastic sheet, plastic sheet on the drive link of movable contact
When being moved with drive link while stir microswitch and cut-off, i.e., letter is connected by connection (or disconnection) state of microswitch
Number.But such a structure easily causes main contacts state and the inconsistent phenomenon of auxiliary contact state because the stroke of microswitch is small,
Contactor function is influenceed, further, since auxiliary contact are arranged on main contacts side, and it is bigger to take up space, and need to reduce main contacts
The arc extinguishing magnet steel of one side, it is unfavorable for the arc extinguishing of main contacts, causes product break performance unstable.
The content of the invention

Contact chip, and for driving the moving contacting plate to move up and down with the transmission core bar with the main stationary contact opening and closing, this moves and connect
Contact is vertically connected on the upper end of the transmission core bar, and the upper surface of the transmission core bar is provided with an auxiliary push-rod, described
Shielding case to should auxiliary push-rod position be provided with a circular hole, the auxiliary push-rod upper end is placed through in the circular hole；On the shielding case
Further respectively have auxiliary contact and the lower auxiliary contact lower auxiliary contact are arranged on this below auxiliary contact, the auxiliary pushes away
Bar can drive the lower auxiliary contact to be switched on and off with auxiliary contact on this when being moved up and down with the transmission core bar.
As a further improvement on the present invention, auxiliary contact neck and lower auxiliary contact are respectively equipped with the shielding case
Neck, the upper auxiliary contact are placed on this in auxiliary contact neck, and the lower auxiliary contact are placed in the lower auxiliary contact
In neck.
As a further improvement on the present invention, the upper auxiliary contact neck, one end of lower auxiliary contact neck connect simultaneously
Form V-structure.
As a further improvement on the present invention, divide on the other end of the upper auxiliary contact neck, lower auxiliary contact neck
It She You not be used to limit the upper auxiliary contact, the plastic sheet of lower auxiliary contact.
As a further improvement on the present invention, the upper auxiliary contact and lower auxiliary contact are a reed, the reed
One end is curved and the other end of the reed is externally provided with a lead-out wire.
As a further improvement on the present invention, the auxiliary push-rod is plastic push-rod.
As a further improvement on the present invention, the transmission core bar lower end is externally provided with coil, iron core and return spring.
The beneficial effects of the invention are as follows：The high pressure sealing D.C. contactor with auxiliary contact on shielding case by setting
Circular hole and upper and lower auxiliary contact, while be driven on core bar upper surface and auxiliary push-rod is set, auxiliary push-rod is transported up and down with transmission core bar
Move and drive lower auxiliary contact and upper auxiliary contact to be switched on or switched off, so as to which main contact contact is switched on and off into state progress
Judge.Because auxiliary push-rod is arranged on transmission core bar upper surface and upper and lower auxiliary contact are arranged on shielding case, therefore take empty
Between it is very small, it is not necessary to arc extinguishing magnet steel is sacrificed, so that the service behaviour of contactor is more stable.
