Abstract
An automatic circuit breaker has a moving switching link (5) on which a supporting lug (4) is arranged which can pivot with respect thereto. The supporting lug (4) supports a latch bearing (6) and a latch (3) (which can be latched to one another) such that they can pivot. The latch (3) is coupled to an operating knob (1) via a clip (bracket) (2). The bearing (7) for the latch (3) on the supporting lug (4) can be used to operate a contact position indicator (8) and a further switching link. The supporting lug (4) improves the tripping behaviour of the automatic circuit breaker, since the latch bearing (6) and the latch (3) are not mounted directly on the switching link (5), so that the switching link (5) is relieved of load.

The driving head of swivel bearing in casing is by spring 1 ' the be loaded on position of rotation that coincide with disconnected position shown in Fig. 1 and Fig. 3.
Driving head 1 is by ratchet 3 couplings of the switch lock of stretch bow 2 and automatic switch.Ratchet 3 by pin 7 or the tubular rivet swivel bearing that plays the bearing effect on loading plate 4.Ratchet 3 is the U-shaped structure, wherein has to hold on two pivoted arms of ratchet 3 to receive the hole of pin 7 (or tubular rivet).A projection 9 is arranged, this projection back that is engaged in the shoulder 10 of ratchet holder 6 as described below, thereby the locking of realization ratchet 3 and ratchet holder 6 on the strut rail of ratchet 3.
Loading plate 4 is the U-shaped structure, and passes through tubular rivet 12 swivel bearings on contact carriage 5 in its pivoted arm scope.Also insert pin 7 (or tubular rivet) in the perforate on the pivoted arm of loading plate 4, thereby the pin 7 of the ratchet 3 of swivel bearing on loading plate 4 and tubular rivet 12 insert respectively in two dead eyes of loading plate 4, thereby produce the load of symmetry.
Torsionspring 16 warps insert around the projection 14 of the dead eye of the axle 11 on the ratchet holder 6.The gib head 4 of one end 16 of torsionspring 16 ' hang over loading plate 4 ' on, the other end 16 of torsionspring 16 " hang over the hook 6 of ratchet holder 6 ' on.16 pairs of ratchet holder of torsionspring 6 load, and ratchet holder 6 and the ratchet 3 adjacent ends with shoulder 10 are moved to ratchet 3.
The dead eye (Fig. 4 and Fig. 5) of elongated hole 20 structures is arranged on contact carriage 5, and the rotating shaft 11 that is fixed on the casing passes this hole, and loading plate 4 and ratchet holder are inserted on the rotating shaft 11 by its dead eye.
The traction bow 13 of the armature 17 of excitation release 17 ' match with end 22 (Fig. 2 bottom) corresponding to ratchet 3, bimetallic releaser 27 driving member 21 by acting on ratchet holder 6 matches with the end 22 corresponding to ratchet 3.Force direction with torsionspring under ratchet holder 6 acts at excitation release 17 or by the traction bow 13 that bimetallic releaser 27 is passed is opposite, when promptly being rotated counterclockwise as shown in Figure 2, the projection 9 of ratchet 3 is discharged by the shoulder on the ratchet holder 6 10, and ratchet 3 (Fig. 2) turns clockwise, thereby causes by the ratchet 3 and the bow 2 configuration bendings that constitute that stretch.The stiff spring 15 traction contact carriage 5 that hang over simultaneously on the hole 19 on the contact carriage 5 are rotated around the axle 11 that is fixed on the casing, make it to break away from the contact that is fixed on the casing.Automatic switch returns to Fig. 1 and disconnected position shown in Figure 3 at most like this.
When contact carriage 5 during to disconnected position shown in Figure 3 rotation, ratchet is locked in again on the ratchet holder 6, this is because ratchet holder 6 is rotated to ratchet 3 directions by torsionspring 16 on the one hand, and ratchet 3 bow that is stretched 2 rotates under the effect of driving head 1 on the other hand, be locked in the back of the shoulder 10 of ratchet holder 6 until the projection 9 of ratchet 3, torsionspring 1 ' clockwise direction that top driving head 1 is established in it loads.Counterclockwise rotate to the logical position shown in Fig. 2 again by driving head 1, contact carriage 5 is rotated and automatic switch recloses.
Because loading plate 4 can be corresponding to contact carriage 5 rotation, thereby loading plate 4 and ratchet holder 6 can be rotated around a common axle (being made of the rotating shaft 11 that is fixed on the casing).When be fixed on casing on the end of the contact carriage 5 that cooperates of contact contact with contact on being fixed on casing, during promptly closed the end, contact carriage 5 continues to rotate around the end of contact carriage 5 and contact point between the contact that is fixed on the casing, this is because the rotating shaft 11 that is fixed on the casing is inserted in the slotted hole 20 of contact carriage 5, and therefore contact carriage 5 can move corresponding to rotating shaft 11.When logical position, the end adjacent that rotating shaft 11 no longer contacts slotted hole 20 on the contact carriage 5 with ratchet holder 6, but remain with certain distance with this end.Therebetween, for discharging crucial parts, be that ratchet 3 and cooperatively interacting of ratchet holder 6 do not change, this is because these two parts are not directly to be bearing on the contact carriage 5, but be bearing on the loading plate 4, loading plate 4 finishes in closing course, and contact carriage 5 is carried out above-mentioned when mobile, does not move corresponding to ratchet 3 and ratchet holder 6.And subsequently with impact the armature release, exactly, the end 22 of the ratchet holder 6 that matches with the traction bow 13 of bimetallic releaser and the state of driving member 21 no longer change.
In the form of implementation shown in Fig. 1,4 and 5, also add and have a contact position indicating device 8.This contact position indicating device 8 in casing, and has a sweep 24 around axle 23 swivel bearings, and this sweep matches with a perforate on the enclosure wall, and can watch from the outside by this perforate.In addition, contact position indicating device 8 have a lever arm 8 ', lever arm 8 ' on the fluting recessed 28 of a bending is arranged.The pin 7 of ratchet 3 swivel bearings on loading plate 4 insert the lever arm 8 of contact position indicating devices 8 ' on recessed 28 in, thereby contact position indicating device 8 servo-actuateds when contact carriage disconnects and be closed, and indicate the position of contact carriage 5, promptly logical position and disconnected position.
