Definitions
- the invention relates to a coil for an electromagnetic relay with a coil body which forms a cylindrical coil tube in its basic form as a carrier for a winding package and two flanges as respective axial boundaries of the winding frame.
- winding-carrying coil former also has a coil tube in the form of a cylinder.
- the winding made of thermoplastic coated copper round wires is applied under tension to this coil tube in the winding space between the two flanges, so that the winding package is initially fixed and immobile
- the winding ends are connected, for example, to connecting wires in the coil flanges, with strain relief usually being provided so that the winding ends under tension are subject to changes due to temperature or mechanical stress.
- the winding package on the coil tube is loose and can be moved in the axial and radial directions. Additional external forces such as vibrations, shock loads and temperature changes pose a risk of interruption
- the object of the invention is to design a coil of the type mentioned in such a way that such external forces, even when the winding package shrinks, cannot lead to displacements or rotations of the winding and thus to a risk to the winding ends.
- this object is achieved in that at least one projection engaging in the winding package is formed on the outer circumference of the coil tube.
- a plurality of nasal or conical projections is preferably arranged in a common radial plane distributed over the circumference of the coil tube. The arrangement of the projections in a single radial plane prevents tensions within the winding package from being caused by the projections.
- the Au ⁇ .mid the "coil tube has auf ⁇ at least one flat from which a projection in the form of a bead protrudes.
- This bead may, for example, as a continuation of Kreisquer ⁇ section of the other coil tube circumference.
- FIG. 1 and 2 a coil former with indicated winding in a partially sectioned side view and in cross section, Figures 3 and 4, a further embodiment of a coil body in a perspective sectional view and in side view.
- the coil shown in FIGS. 1 and 2 has a coil body 1 which has a coil tube 2 and two flanges 3 and 4.
- the coil tube 2 has a circular cross section and an inner bore for receiving an iron core (not shown).
- a winding 5 made of thermoplastic is wrapped. Wrapped copper wire. The beginning of the winding 6 is first fastened to a connecting pin 7 which is anchored in the coil flange 3.
- a compact winding package 5 is formed by the wire insulation becoming baked, which can sit loosely on the coil tube 2 after a certain time.
- the coil tube 2 has conical knobs 8, which are arranged near the start of the winding 6 on a common radial plane. These knobs 8 already drill into the winding package from the inside when the winding is applied and thus prevent later movement. Since the knobs 8 are in the vicinity of the coil flange 3, the shrinking winding package is pulled in the direction of the end of the winding 6 at risk, so that stress in the longitudinal direction is avoided.
- FIGS. 3 and 4 A somewhat modified embodiment is shown in FIGS. 3 and 4.
- a coil former 11 has a coil tube 12 with flanges 13 and 14.
- a winding 15 is applied to the coil tube, with a winding start 16 being fastened to a connecting pin 17 in the coil flange 13.
- the coil tube 12 has lateral flats 18, so that the winding package 15, which is adapted to the outer circumference of the coil tube, cannot be rotated on the coil tube even with a certain shrinkage.
- the flattening 18 is interrupted in each case by a bead 19 in the vicinity of the start of the winding 16, in which case the bead is designed as a continuation of the circular surface of the coil tube 12.
