Description
Technical field
The present invention relates to a kind of D.C. contactor, particularly relate to a kind of D.C. contactor auxiliary contact.
Background technology
At present, on market, existing seal DC contactor is with auxiliary contact, being opened or closed and main tactile of auxiliary contact
Point keeps consistent, and for judging the state of main contacts, i.e. main contacts is off or closes.These existing auxiliary contact use and are producing
The sound contact chip of auxiliary contact is set inside product, when the mechanism section action of main contacts, drives auxiliary contact to move simultaneously and connect
Contact action, so that auxiliary contact keep consistent with the state of main contacts.But the structure of this auxiliary contact is complicated, to product
Design, part processing, finished product assembling process require higher.
Summary of the invention
In order to overcome drawbacks described above, the invention provides a kind of D.C. contactor auxiliary contact, use magnetic field induction former
Reason is made, it is not necessary to from interiors of products leading-out terminal, enormously simplify structure design and the product assembling product process of product.
The present invention is to solve that its technical problem be the technical scheme is that a kind of D.C. contactor auxiliary contact,
Moving contact including the main contacts for driving this D.C. contactor moves up and down so that its static contact with this main contacts is connected
With the power transmission shaft disconnected, and auxiliary contact consistent with this main contacts kinestate；Described power transmission shaft upper end is connected described dynamic
Contact, lower end external stability is arranged with dynamic iron core；Described auxiliary contact include tongue tube, permanent magnet, the first pure iron sheet and second
Pure iron sheet, this first and second pure iron sheet is symmetricly set in immediately below described power transmission shaft, and between having between this first and second pure iron sheet
Gap；This permanent magnet is fixed on the second pure iron sheet, even if described power transmission shaft moves downwardly to the described moving contact of bottom and stationary contact
When head is in off-state, this power transmission shaft is against this permanent magnet；This tongue tube is arranged at this first and second pure iron sheet one side；Described
The circle outer Monday of dynamic iron core is also arranged with pure iron part, and this pure iron part upper end extends to outside described dynamic iron core, this pure iron zero
Part lower end extends on described first and second pure iron sheet.
As a further improvement on the present invention, further respectively have below described first and second pure iron sheet for support this
One, first and second working of plastics of two pure iron sheets.
As a further improvement on the present invention, described power transmission shaft upper end is movably set in magnetic pole core, and this power transmission shaft is positioned at
It is additionally provided with back-moving spring outside part between this magnetic pole core and dynamic iron core.
The invention has the beneficial effects as follows: these D.C. contactor auxiliary contact, use tongue tube, place on tongue tube side
One permanent magnet, uses pure iron sheet to guide magnetic circuit to guide, and the master being installed to D.C. contactor according to pre-designed position touches
Point mechanism adnexa, when main contacts mechanism section moves, the position of dynamic iron core can change, and then changes original magnetic circuit trend,
The state of tongue tube changes therewith, and then the state of instruction main contacts.These auxiliary contact utilize magnetic principles, from without from
Interiors of products leading-out terminal, enormously simplify internal structure and the assembling process of product, and cost reduces the most accordingly.

Detailed description of the invention
In conjunction with accompanying drawing, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment, the most in every case
The simple equivalence change made with scope of the present invention patent and description and modification, the most still belong to patent of the present invention and contain
Within the scope of lid.
As shown in figures 1 to 6, a kind of D.C. contactor auxiliary contact, including the main contacts for driving this D.C. contactor
Moving contact 102 move up and down so that the power transmission shaft 103 that switches on and off of its static contact 101 with this main contacts, and with this
The auxiliary contact that main contacts kinestate is consistent；Power transmission shaft upper end is connected moving contact, and lower end external stability is arranged with dynamic iron core
104；Auxiliary contact include tongue tube 1, permanent magnet the 2, first pure iron sheet 3 and the second pure iron sheet 4, and this first and second pure iron sheet is symmetrical
It is arranged at immediately below described power transmission shaft, and between this first and second pure iron sheet, there is gap；This permanent magnet is fixed on the second pure iron sheet
On, even if this power transmission shaft is against this permanent magnet when power transmission shaft moves downwardly to bottom moving contact and static contact is off-state；
This tongue tube is arranged at this first and second pure iron sheet one side；Enclosing in the outer Monday of dynamic iron core and be also arranged with pure iron part 5, this is pure
Ferrum part upper end extends to outside dynamic iron core, and this pure iron part lower end extends on first and second pure iron sheet.
Preferably, further respectively have below first and second pure iron sheet for support this first and second pure iron sheet first and second
Working of plastics 7,8.
Preferably, power transmission shaft upper end is movably set in magnetic pole core 105, this power transmission shaft be positioned at this magnetic pole core and dynamic iron core it
Between part outside be additionally provided with back-moving spring 106.
Fig. 1 is auxiliary contact structural representation of the present invention, and it is by tongue tube, permanent magnet, first and second pure iron sheet, with
And first and second working of plastics composition, permanent magnet is fixed on the second pure iron sheet, and its mounting means is as shown in Figure 2.As it is shown on figure 3, just
Often under state, main contacts disconnects, and dynamic iron core is near permanent magnet, by the magnetic field short circuit of permanent magnet, magnetic field without tongue tube (such as Fig. 5
Shown in the middle direction of arrow), tongue tube disconnects.As shown in Figure 4, when product is energized, dynamic iron core motion drives power transmission shaft to move upward,
The moving contact making main contacts contacts with static contact, i.e. main contacts Guan Bi, and now, dynamic iron core is away from permanent magnet, and magnetic field is through overdrying spring
Pipe (as shown in the direction of arrow in Fig. 6) so that it is Guan Bi.
