Description
Technical field
The utility model relates to a kind of side-mounted A.C. contactor that is loaded in the closure, the closed interchange contact of especially a kind of modularization.
Background technology
A.C. contactor of the same type, the mode as external CT type A.C. contactor adopts upper and lower shell to fasten is provided with electromagnetic system and contact system two large divisions in the shell.Electromagnetic system comprises yoke and armature and coil three parts; Contact system comprises fixed contact and is contained in the contact bridge of contact in supporting that the contact support links to each other with armature.Last cover top portion has form, and the contact support is provided with " L " type first finger and shows arm, and the side of being, the side annular of indication arm on the corner is provided with two rotating shafts and coil rack and is rotationally connected, and is provided with back-moving spring between indication arm and the shell.Behind the coil electricity, armature overcomes the active force of stage clip under the effect of electromagnetic force, drives the contact support and moves upward together, and main circuit is connected, and indicates arm also to rotate around the axis simultaneously, and its top is attached on the form, thereby shows the closure state of contact; Behind the coil blackout, armature falls the contact support under the effect of deadweight and stage clip, indicates the arm top also to leave form simultaneously, represents that with this contact is in the disjunction state.The contactor of this structure has following shortcoming: the one, and stage clip is by indicating the arm indirectly-acting in the contact support, and the breaking speed of contact is slower; The 2nd, the connected mode of coil exit is unreliable; The 3rd, adopt and rotate indication arm configuration complexity, show undistinct; The 4th, the upper and lower structure of housing, the Mould Machining complexity, cost is higher.
Summary of the invention
The purpose of this utility model provides the closed A.C. contactor of the novel modularization of a kind of structure, to overcome the above-mentioned defective that existing similar A.C. contactor exists.
For achieving the above object, the closed A.C. contactor of the modularization that the utility model provides comprises shell, electromagnetic system and contact system, described electromagnetic system comprises yoke, armature and coil, described contact system comprises contact and is contained in moving contact and the touch spring of contact in supporting, contact system is provided with reaction spring, it is characterized in that also being provided with running indicator spare, running indicator spare is a light-emitting diode, described coil is made up of two parts, the side is the former limit as the operation electriomagnet control coil, and the outside is wound with the secondary as LED power source.Adopted with the indication of light-emitting diode as the operating condition of A.C. contactor, it have clear display, bright, angular field of view is wide, the advantage that visual range is far away and sees through form and observes the effect of indication arm and compare and have fairly obvious advantage.
Be also reaction spring to be designed to the single line spring simultaneously as further improvement of the utility model, wire spring little groove being connected with armature of intermediate sleeve contact support in, other is through on the coil rack at two ends.Substitute two reaction springs with the single line spring, reach the purpose that the contact support is resetted equally, thereby reduced part, and the processing of wire spring is also easy than torque spring, the isochrone spring directly acts on the contact support, thereby contact has higher breaking speed.
Be to simplify the design of coil lead-out mode as another improvement of the present utility model, changed and be connected to mode on the ramp with lead-out wire from brace more earlier through lug plate, take directly lead and ramp to be coupled together with lead-out wire, and lead-out wire embedding jail fixed with adhesive again, thereby reach the purpose of saving part, simplifying technology in the groove of coil rack.
Below in conjunction with drawings and Examples technology contents of the present utility model is described further.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be A-A of the present utility model to cutaway view.
Fig. 3 is an outline drawing of the present utility model.
Embodiment
As shown in drawings, the closed A.C. contactor of this modularization comprises shell, electromagnetic system and contact system three big major parts.Electromagnetic system comprises yoke 1, armature 2 and coil 14.Coil is made up of two parts: the side is the former limit as the operation electriomagnet control coil, and the outside is wound with the secondary as light-emitting diode 16 power supplys, and they all are wound on the coil rack 15 that plastics make.The yoke flexible fastening of " E " type is on the top of coil rack 15, the armature 2 of " E " type by little axle 3 and contact support 4 combine can be in coil rack moving linearly.Contact system mainly comprises: be fixed on the fixed contact 9 on the supporting member and be contained in contact and support movable contact bridge 8 and touch spring 5 in 4.The contact support is fixed on the below of yoke by little axle 3, and the two ends of the wire spring 7 of a counter-force are through in two apertures of coil rack 15 bottoms and can be free to slide, and intermediate sleeve is supported 4 motions with armature 2 and contact in the groove of little axle 3.Control coil lead-out wire 12 tightly is embedded in the dedicated slot of coil rack 15, and again with adhesive glue jail, its two poles of the earth link to each other with the two ends on former limit respectively.Shell is divided into left shell 18 and right casing 17, two cover top portion and merges the limit and respectively be provided with half hole, merges into a circular hole, and light-emitting diode 16 is inlaid in the merging hole of centre of left and right sides shell.Termination 11 is wiring place of main circuit; Termination 13 is wiring place of control coil; The card rail 6 that is positioned at the bottom is contactor is installed usefulness on 35mm standard mounting rail securing members.
The course of work of the present utility model is such: control coil energising back armature overcomes the counter-force of wire spring under the effect of electromagnetic attraction, be with the contact support to move upward together, movable contact bridge in contact support this moment is just connected with fixed contact, has realized the purpose of main circuit energising.Meanwhile respond to the generation correspondent voltage immediately light-emitting diode is lighted, shown that contactor is in operating state around the secondary winding of control coil outside; Behind the coil blackout, armature and contact are supported under the counter-force effect of wire spring and get back to the origin-location, and the movable contact bridge also separates with fixed contact, make the main circuit outage, and this moment, light-emitting diode extinguished at once, and the expression contactor is in the state of quitting work.
