Definitions
- Electric coil in particular for a relay, and method for the production thereof.
- the invention relates to an electrical coil with a coil former, an excitation winding arranged on the coil former between flanges and with a sheathing made of insulating material arranged over the excitation winding.
- the invention also relates to a method for producing such a coil.
- the aim of the invention is to design a coil with a sheathing in such a way and to specify a method for its production that this sheathing enlarges the coil diameter only as little as possible and can be produced with little manufacturing effort.
- this object is achieved in the case of a coil of the type mentioned in the introduction in that the sheathing in the form of a peripheral insulation winding with at least one Winding layer of an insulating fiber is formed, the adjacent windings are glued to a continuous insulating layer.
- a sheathing in the form of an additional winding with an insulating fiber is provided which, after the excitation winding has been wound, is applied in the same way and with the same winding machine in one or, if necessary, in several layers above the excitation winding and is also glued to the flanges.
- the method according to the invention for producing such a coil consists in that after winding the field winding an at least single-layer insulation winding made of an insulating fiber is applied over the field winding and that the individual turns of the insulation winding are glued together.
- the insulating fiber itself can preferably consist of thermoplastic, the fiber being melted by a subsequent heat treatment and the individual turns being glued to one another, or a mineral fiber can be used which is impregnated with a casting resin, for example a thermoset resin and hardens after winding.
- a casting resin for example a thermoset resin and hardens after winding.
- automatic curing at room temperature or curing by heat treatment can be considered. In principle, it would also be conceivable to impregnate the fiber with resin only after winding, which is then distributed through the fiber.
- FIG. 1 shows a relay coil designed according to the invention in a side view with the coil winding partially cut open
- FIG. 2 shows the coil of FIG. 1 in a top view.
- the coil shown in the drawing has a coil body 1 made of plastic, which forms a coil tube 2 and at the ends of each a flange 3 or 4. In the flanges 3 and 4, pairs of coil connecting pins 5 and 6 are embedded in pairs.
- An excitation winding 7 is wound in a conventional manner on the coil tube between the two flanges 3 and 4.
- a single-layer or multi-layer insulation winding 8 is also arranged above this winding 7.
- This insulation winding can consist of a mineral fiber which was impregnated with thermoset resin before winding, but is otherwise wound in the same way as the excitation winding 7. After winding, the thermoset resin hardens by tempering. Instead of the impregnated mineral fiber, a fiber made of a thermoplastic can also be used, the fiber material being melted by heat treatment after winding, so that in this case too, as in the previous case, the individual turns of the insulation winding stick to one another.
- this insulation winding also sticks at its ends to the coil flanges 3 and 4, so that a closed sheath is produced over the excitation winding.
- the winding ends 8a and 8b of the insulation winding can, for example, on the unused pins
- the ends of the insulation winding can also be wound onto the same connection pins 6 over the ends 7a and 7b of the excitation winding. to which the wire connections were previously contacted by soldering or welding.
