Definitions
- the invention relates to an overcurrent release according to the preamble of claim 1.
- B. become known from DE-OS 31 49 811.
- separate calibration elements are provided on both sides of each bimetal strip, each of which is arranged in chambers of the release bridge, on the one hand, and the differential bridge, on the other, that are open on one side.
- These calibration elements are arranged opposite one another and are in contact with the bimetal strip. After adjustment, they are cast with a hardening plastic compound.
- These calibration elements are designed and held in the chambers in such a way that they are positively and non-positively applied to both sides of each bimetallic strip during the calibration or adjustment process.
- the initially loosely arranged calibration elements are to be fixed in such a way that, with uniform heating of all existing bimetal strips, the subsequent switch lock of a switch is only actuated when the release bridge and the differential bridge have exceeded the calibration position once defined due to the joint effect of all bimetal strips.
- the tripping bridge should be held firmly and only the differential bridge should be deflected to such an extent that the switch lock is triggered.
- the invention is based on the object of creating a reliably adjusted bimetallic release of the type mentioned at the beginning and of reducing the effort required for the adjustment.
- the creation of such a bimetal trigger is characterized by the characteristics of
- Each bimetallic strip has an opening at its release end for receiving a calibration element, which, after being inserted into this opening, is supported both on the release bridge and on the Differen.tial Hampshire and moves in the opening when the bridge is moved during the adjustment process for fastening after adjustment, can move freely.
- Fig. 1 shows a side view
- Fig. 2 is a plan view of an adjusted bimetallic release
- 3 and 4 show two side views of a trigger according to FIG. 1 during the adjustment process.
- 5a to c show different designs of a bimetal at its release end.
- 6 and 7 schematically show a top view and a side view of a device for deflecting a bimetallic release according to FIGS. 1 to 4 during the calibration process.
- Hg. 7a shows a detail of Fig. 7.
- 1 to 4 has a trigger bridge 10, which is mounted at 11 in the housing or frame of a switch, not shown.
- On the release bridge 10 a differenti & bridge 12 is rotatably supported at 13.
- On the differential bridge 12 there is a transmission
- FIGS. 3 and 4 show two phases of the calibration method for producing the calibrated state according to FIGS. 1 and 2.
- a device according to FIGS. 6 and 7 is used. This device is mounted in the pivot point 11 of the release bridge and each has two bridges assigned to a bridge Claws 22.23. Two opposite claws 22 and 23 are connected to each other by a spring 24. 3 and 4, the opposing walls of the release bridge 10 and differential bridge 12 run parallel to each other. In order to compensate for tolerances, they can also be weakly conical, as the detail according to FIG. 7a shows.
- the calibration elements 19 are loosely inserted into the openings 21 of the bimetallic strips 17. Then they are made using the device Fig. 6 and 7 positively brought to Ausl Harborbrü ⁇ ke 10 and Differe ⁇ t ialmaschine 12. By turning the device around the point 11 in the direction 25, the bridges 10 and 12 with the calibration elements 19 clamped between them are brought to the trigger point 15 of the switching mechanism. This position is shown in Fig. 3. When triggered, the device is stopped and the bimetals 17 are in this position, for. B. by heating, brought into the position in which the triggering must take place. This process is shown in Fig. 4. In this position, the calibration elements 19, z. B. by laser welding, firmly connected to the bimetals. (Welding points 20.
- the advantage of the present invention is that only one calibration element is required per bimetal strip. This and the type of arrangement of this calibration element on the bimetallic strip result in low calibration effort and the possibility of carrying out a simple and reliable adjustment.
- the method for carrying out the calibration also corresponds to that of the first-mentioned exemplary embodiment, the device for carrying out the method having to be adapted accordingly to the changed position of the bimetal strips.
