Definitions
- the invention relates to an inductive miniature component for SMD assembly with a coil carrier made of plastic or ferrite material, in or on which at least one coil winding is arranged, whereby on one outside of the coil carrier and in one piece with this projecting connection pins are arranged, around each of which a End of the winding wire of a coil winding is wound around in several turns, and a method for producing such a component.
- Such an inductive miniature component with a coil carrier made of ferrite material is described, for example, in German Utility Model No. 298 24 118.8.
- the invention has for its object to form an inductive miniature component for SMD assembly with the features specified at the beginning and in the preamble of claim 1 such that even when using winding wires with a very thin diameter, the risk of the end of the winding wire tearing off even in the event of shock - Vibration exposure is significantly reduced.
- the basic idea of the invention is not to wind the respective end of the winding wire directly onto the connecting pin, but to first encircle the connecting pin with a wire in several turns. The end of the winding wire is then wound around in several turns on the resulting metallizing wire winding surrounding the connecting pin.
- the previous wrapping of the connecting pin with an electrically conductive wire of larger diameter creates wide metallized areas that are similar to metal connections. It has been shown that connections can be achieved in this way that are mechanically much more stable than connections in which the end of the winding wire is wound directly onto the connecting pin.
- the diameter of the wire of the metallizing wire winding should be so large that its tensile strength is sufficient to meet the demands placed on the component with regard to impact and shaking stress. It has turned out that it is favorable if the wire of the metallizing wire winding has a diameter which is at least twice as large as the diameter of the winding wire.
- the wire of the metallizing wire winding can be a CuAg wire, but also a tinned Cu wire can be used or a wire made of an alloy with higher tensile strength, such as bronze.
- connection technology according to the invention can be used both for coil carriers made of plastic material and for coil carriers made of ferrite material and ceramic plates.
- the arrangement of the connecting pins is arbitrary and can be adapted to the respective needs. Exemplary embodiments of an inductive miniature component according to the invention are explained in more detail below with reference to the accompanying drawings
- FIG. 1 shows a miniature inductive component, which is designed as a transponder coil, in a top view
- Fig. 2 shows the component of Figure 1 in section along the line 11-11 in Fig. 1.
- FIG. 3 shows a view of the component according to FIG. 1 from the bottom side
- FIG. 4 shows a partial view of the component according to FIG. 1 in the region of a connecting pin, in an enlarged representation compared to FIG. 1;
- FIG. 5 shows a top view of the coil carrier of a miniature component, which is designed as a hood, without a coil winding;
- FIG. 6 shows a section through the coil carrier according to FIG. 5 along the line A-B;
- FIG. 7 shows a partially sectioned view of the coil former according to FIG. 5 from the direction VII in FIG. 5;
- FIG. 8 is a top view of a coil carrier designed as a ceramic plate for double-hole core transformers
- FIG. 9 is a top view of a coil carrier designed as a ferrite winding body for an inductive component.
- a transponder coil is shown with a coil carrier 1 designed as a hood, into which a coil winding 2 is inserted.
- the coil carrier 1 has an octagonal plan and is made of plastic material.
- connecting pins 1.1, 1.2, 1.3 and 1.4 are arranged, which are integrally connected to the coil carrier.
- the connecting pins 1.1 to 1.4 are arranged in the transverse direction to the coil axis.
- the ends 2.1 to 2.4 of the coil winding 2 are wound in several turns around the connecting pins 1.1 to 1.4.
- connection technology using the example of the connecting pin 1.1. It can be seen that between the surface of the connecting pin 1.1 and the turns 2.1 of the winding wire end wound around it there is a metallizing wire winding 3.1, which consists of an electrically conductive wire whose diameter is larger than that
- FIGS. 5 to 7. This in turn is a bobbin 4 designed as a hood, which has a rectangular plan, and the connecting pins 4.1, 4.2, 4.3, 4.4, 4.5, 4.6 are each arranged on two opposite side walls of the bobbin 4.
- the connection of the ends of the winding wire, not shown, of the coil winding, also not shown, is carried out in the same way as described with reference to FIG. 4.
- FIG. 8 Another example is the coil carrier 5 shown in FIG. 8, which is designed as a ceramic plate for a double-hole core transformer and has connecting pins 5.1, 5.2, 5.3 or 5.4 and 5.5 on the opposite side faces.
- the coil carrier 6 is designed here as a ferrite winding body with two connecting pins 6.1 and 6.2 on the opposite sides of the winding body.
- One end 7.1 of the winding 7, which is otherwise only indicated, is wound in several turns around the connecting pin 6.1 after a metallizing wire winding 8.1 has also been applied to it in several turns from a wire whose diameter is larger than the diameter of the winding wire.
