Definitions
- the invention relates to an overcurrent release a U-shaped yoke, a coil winding, a pole and an armature, with an air gap between the pole and the armature exists and the coil winding between the two Legs of the yoke is arranged.
- an overcurrent release is described for example in EP-A-0 326 449.
- a generic device is used for instantaneous overcurrent releases used as known in circuit breakers for switching and protecting motors and others Consumers.
- These undelayed Overcurrent releases are designed as electromagnetic releases, which is essentially a coil winding, a coil former, an anchor, a pole, a plunger, a retaining spring and include a yoke.
- the anchor pulls at a certain one Rated current of the circuit breaker, e.g. at the twelve times the rated current for motor protection or 19 times Rated current at the transformer protection.
- the anchor movement works on a key switch and on a moving contact to open the contacts. According to the standard (IEC60947) the Response current fluctuate by a maximum of ⁇ 20%.
- the coil winding is opened a bobbin wound.
- the bobbin is provided with a flange on which the Winding wire is present.
- the bobbins are mostly multi-layer wrapped and the last layer for fixation with one Adhesive tape bandaged.
- the coils form a compact one Unity avoiding the above problems.
- the coils are attached Windings made to prevent high short-circuit currents pull the coil together and can deform.
- the invention has for its object a device with a coil winding to create a positioning allows the coil winding in its axial direction.
- the object is achieved in that between the coil winding and one of the two legs of the yoke an adjustment ring is provided as a variable spacer between the Coil winding and the yoke acts, and that by twisting the adjustment ring the position of the coil winding to the air gap is changeable in the axial direction.
- adjustment ring is provided with an external toothing. This enables easy adjustment by hand or by machine a manufacturing facility.
- the overcurrent release 1 shows the essential components of an overcurrent release 1 is shown in an exploded view for Circuit breakers for switching and protecting motors and other consumers.
- the overcurrent release 1 is essentially a U-shaped yoke 2, a coil winding 3, a coil former 4, an armature 5, a pole 6 with an associated plunger 7 and an adjustment ring 8 composed.
- the overcurrent release 1 in the assembled state in which the coil winding 3 on the coil former 4th is threaded, the coil winding 3 between the two legs of the U-shaped yoke 2 is arranged and the bobbin 4 through an opening in the upper leg of the Jokes 2 protrude through.
- the armature 5 and the pole 6 are located itself in the cavity of the cylindrical bobbin 4, so that in FIG. 2, only the plunger 7 from the coil body 4 at the bottom protrudes.
- the adjustment ring 8 is arranged between the lower leg of the yoke 2 and the Coil winding 3. He owns one pointing to the last turn 9, to the winding wire pitch adapted area 10 and thus forms a large area Support of the coil winding 3.
- Adjustment ring 8 On the inside is the Adjustment ring 8 provided with teeth, not shown here, which engage teeth on the bobbin 4.
- teeth By twisting of the adjustment ring 8 can the coil winding 3 exactly to the air gap between the armature 5 and the pole 2 in the axial direction be positioned.
- the adjustment ring 2 as a spacer acts between the coil winding and the yoke 2 is the The coil winding is thus secured against shifting.
- the said Internal teeth prevent unintentional turning back of the adjustment ring 8.
- the outer circumference is the Adjustment ring 8 provided with a toothing 11, the one easy adjustment by hand or by machine through a manufacturing facility allows.
