Definitions
- the invention relates to an inductive component with a rod core and a winding body, in which current winding layers enclosing the rod core axis are embedded.
- Rod core enclosing winding body to provide a bed for receiving the Has turns of a current winding.
- the current turns embedded in this way lie concentric around the rod core axis.
- the winding former is used in the manufacture of a such inductive component pushed onto the rod core, whereupon the application which connects current turns.
- An example of a known rod core coil shows Fig. 5.
- the invention has for its object the heating of the inductive component counteract.
- the object is achieved in that the width of the innermost layer of current turns is smaller than the rod core length and that the width of the current winding layers is from the inside out increases outside.
- the winding body bed is by the Current turns filled from the inside out, the current turns layers form.
- the width of the current winding layers is in the direction parallel to the rod core axis measure up.
- the reduction in heat loss achieved is due to the fact that in the outer (i.e. closest to the core ends) the innermost (i.e. the current winding positions closest to the rod core during a current flow a high magnetic field strength is generated by the current turns, which is too high Eddy current losses ("proximity" losses) leads.
- proximity Eddy current losses
- the rod core can lose heat emit directly into the surrounding air, which additionally heats up the component counteracts.
- the winding body is preferably designed as a plastic injection molded part, so that winding bodies with any bed profiles inexpensive in mass production are producible.
- the component according to the invention can be used with the realize the same number of current turns a higher inductance.
- the configuration of the winding body There are various possibilities for the configuration of the winding body. Point the side surfaces of the winding body bed from the side of the current turns If you look at the convex profile, the heat loss is particularly high. In other configurations, the side surfaces of the Wrapper body shaped like a truncated cone outer surface, resulting in a simplified Producibility due to the simple winding bed profile on the other hand leads the side surfaces of the bobbin bed also one from the side of the current turns viewed from have a concave profile.
- the invention also relates to a winding body with a winding body bed Inclusion of current winding layers consisting of concentric windings, their Width from the area to accommodate the innermost layers of current turns towards the area for receiving the outermost layers of current turns increases.
- the inductive component is suitable both as a coil and as a transformer to become.
- the inductive component 1 shown in Fig. 1 has a rod core 2, the one Winding body 3 carries.
- the inductive component 1 is designed as a coil, however, the principle according to the invention is also readily applicable to transformers is applicable.
- the winding body 3 forms a bed in which a winding with current turns 4 is embedded.
- the winding body 3 consists of two shells 3a and 3b which are connected to a sleeve 3c, which in turn is pushed onto the rod core 2.
- the current windings 4 form current winding layers, the width of which is determined by the profile of the Coil body bed is determined, what to do from the shape of the shells 3a and 3b of the Coil 3 depends
- the width of the innermost current winding layer is smaller than that Length of the rod core 2.
- the width of the current winding layers increases from the inside outside too.
- the increase in the width of the current turns depends on the shape of the Shells 3a and 3b form lateral surfaces of the winding body bed.
- Fig. 1 point the side surfaces of the wrap bed, i.e. shells 3a and 3b, one from the side the current windings 4 viewed from a convex profile.
- the inductive so formed Component 1 heats up considerably less than when operating with alternating currents conventional inductive components with rod core, since eddy current losses are reduced are and in addition via the exposed ends of the rod core 2 heat to the ambient air can be delivered.
- Figures 2 and 3 show configurations of the inductive component 1 with others Variants of the winding body 3.
- the lateral surfaces of the winding body bed in the form of an outer truncated cone surface.
- the lateral surfaces and thus the shells 3a and 3b are not curved.
- the lateral surfaces of the winding body bed face from the side of the current turns 4 viewed from concave profile. From the current turn side considered, the shells 3a and 3b are curved outwards.
- Fig. 4 shows a side view of the winding body 3 from the side of a rod core end considered.
- the shell 3a and thus the corresponding side wall of the winding body bed has openings 5, which improve heat dissipation to the ambient air enable.
- the shell 3b, not shown, is also designed.
- the winding body 3 is preferably made of plastic and in an injection molding process manufactured so that any profile shapes of the winding body bed for mass production are inexpensive to manufacture.
- the rod core 2 is in particular made of ferrite, but also other soft magnetic materials are considered as rod core material.
- FIG. 5 shows a rod core coil 10 according to the prior art.
- a winding body 12 is pushed on, which serves to receive current windings 13.
- the profile of the winding body bed is rectangular.
- the winding body encloses the Rod core 11 along its entire length.
