Embodiment
By reference to the accompanying drawings; the utility model is elaborated; but protection range of the present utility model is not limited to following embodiment, the simple equivalence namely in every case done with the utility model claim and description changes and modifies, and all still belongs within the utility model patent covering scope.
Consult Fig. 1-3, a kind of closed type D.C. contactor of band signal feedback, the end cap 2 comprising contactor case 1 and be arranged at outside this contactor case port, this contactor case and end cap seal form a cavity, inner frame 3, moving contacting plate 4, drive link 5, iron core 6, coil 7, back-moving spring 8 and two fixed contacts are provided with in this cavity, this iron core is fixedly installed on outside the bottom of this drive link, and is positioned at this coil; The upper end of this drive link is passed and is stretched in this inner frame, and this moving contacting plate is fixed on the upper end of this drive link; This back-moving spring is arranged at outside this drive link, and two ends push against this iron core and inner frame respectively; The two ends of this moving contacting plate form two moving contacts respectively, and two these fixed contacts lay respectively at the top of two these moving contacts.Described moving contacting plate is fixedly connected with a microswitch post rod 9, separately in described inner frame, be provided with a sensitive switch 10, this sensitive switch can be withstood when this microswitch post rod moves up and down with described moving contacting plate and make this sensitive switch conducting and this sensitive switch that can come off that this sensitive switch is disconnected.
The L-type push rod 102 that described microswitch post rod comprises brace 100, holding section 101 and is fixed on this holding section, this brace fixed cover is located on described drive link, and the engaging of this holding section is positioned on this brace.
Described sensitive switch is electrically connected appliance controller by signal feedback line 11, exports closed or cut-off signal to appliance controller.
In described inner frame, be also provided with arc extinguishing magnet steel 12, connected by epoxy glue seal between described contactor case and end cap.
The operation principle of D.C. contactor is: under nature, two moving contacts on moving contacting plate do not contact with corresponding two fixed contacts, when after coil electricity, iron core moves upward under the influence of a magnetic field vertically, power transmission shaft is driven to move upward thus, the moving contacting plate of power transmission shaft upper end moves upward thus together, make two moving contacts upwards with two fixed contact conductings.When after coil blackout, magnetic field dissipate, iron core is not by magneticaction, and power transmission shaft is axial downward movement under the effect of returning spring, and the movable contact spring of power transmission shaft upper end moves downward thereupon, and two moving contacts and two fixed contacts are disconnected.
The present invention owing to being provided with microswitch post rod and sensitive switch simultaneously on the contact chip of above-mentioned D.C. contactor, microswitch post rod and moving contacting plate are synchronized with the movement, thus in its natural state, namely under D.C. contactor disconnection, microswitch post rod does not contact with sensitive switch, sensitive switch disconnects, when D.C. contactor closes, microswitch post rod is synchronized with the movement with the moving contacting plate of D.C. contactor, moving contacting plate move to two moving contacts are contacted with two fixed contacts time this microswitch post rod promote sensitive switch make this sensitive switch close, namely cut-offfing of sensitive switch contacts synchronous switching off with direct current, pass through this sensitive switch connection signal feedback line thus to appliance controller, thus realize D.C. contactor cut-off signal feedback, so that controls D.C. contactor in time cut-offs situation.
