Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The invention relates to an electrical component, in particular a capacitor, which has an electrical connection contact.
[0002]
[Prior art]
In fact, components which are already configured as capacitors are known, in which the connection contacts are configured as connection wires or as thin blade tapes, and the connection contacts are each connected with fixed ends to the electrodes of the component. . With its free end facing this component, the connecting wire or blade tape is soldered to the circuit board. The electrical circuit produced in this way has the disadvantage of requiring a relatively large space. Soldering connection wires or braided tapes to the circuit board is also associated with some manufacturing costs.
[0003]
[Problems to be solved by the invention]
It is an object of the present invention to provide a configuration in which a component of the type described at the outset can be easily connected to other electrical components to form an electrical circuit.
[0004]
[Means for Solving the Problems]
This problem is solved by providing the fork-shaped cut-clamp contact for the solderless cut-clamp connection wiring.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Advantageously, the component with the cut-and-clamp contact can be inserted directly into the other electrical component and / or the connecting wire of the winding wire and contacted therewith. This saves additional auxiliary means, for example, conductor tracks and / or solder means. This component also allows for a connection with other electrical components in a structural and cost-saving manner.
[0006]
Advantageously, the cut-clamp contacts are arranged parallel to one another with their direction of extension. In this case, the component can more easily be inserted or pressed into the connection wires of the other electrical components. In this case, a plurality of cut / clamp contacts provided on the component can be simultaneously connected to connection wires of other components in one operation step.
[0007]
In a preferred embodiment of the invention, the fork-shaped cut-and-clamp contacts are arranged on the mutually facing end faces of the component, in particular on the mutually facing end faces. By arranging the cut-clamp contacts on both sides of the component, the cut-clamp contacts can be pressed more easily against the connecting wires of other components. This is done by applying pressure to the back of the component opposite the cut-clamp contact.
[0008]
Advantageously, the at least one connection contact has two cut-and-clamp contacts laterally spaced from one another, which are integrally connected to one another at a fixed end. The connecting contacts can optionally also be inserted simultaneously into a plurality of connecting wires of other electrical components, so that they can be connected to one another and to the connecting contacts. The mutually separated cut-clamp contacts furthermore prevent the electrical component from tilting laterally when the cut-clamp contacts are pressed.
[0009]
In an advantageous embodiment of the invention, the connecting contacts are angled at their ends facing the cut-clamp contacts to form a mating aid. The pressure required to press the cut-clamp contacts against the connecting wires of the other electrical components is transferred to the connecting contacts in a relatively large area in this fitting aid. This allows the electrical component to be more easily connected to other electrical components.
[0010]
In an advantageous embodiment of the invention, the electrical component is embodied as a film capacitor with at least two electrodes, each of which has a plurality of electrode layers. Here, the electrode layers of the individual electrodes are connected to one another by a scoop layer, and the electrical connection contacts are attached to this scoop layer and are preferably welded thereto. This provides a good electrical connection between the electrodes of the capacitor and the connection contacts. Welding the connection contacts with the scoop layer can also be performed inexpensively with standard tools existing in the electrical industry. The electrical components can be configured as film capacitors, coil capacitors, or ceramic capacitors.
[0011]
Advantageously, the connecting contacts are configured in a substantially H-shape with two longitudinal legs interconnected by a transverse web. The longitudinal legs have one leg on each side of the transverse web, each longitudinal leg being connected at its leg to the scoop layer and having cut-clamp contacts on the other leg. In this case, the connection contacts can be made with a saving in material, but still have a high mechanical load capacity.
[0012]
In a preferred embodiment of the invention, the components are configured symmetrically with respect to the center plane and / or the center line. In this case, the component can be manufactured at a lower cost. Furthermore, it can be handled well when attached to a circuit device.
[0013]
【Example】
The electrical component, generally designated by 1, is configured as a film capacitor having two electrodes separated from one another by a dielectric. The electrodes each have a plurality of electrode layers not shown in detail in the drawing. Adjacent electrode layers of different electrodes are each separated from one another by a dielectric layer therebetween. The layer staple formed from the electrode layer and the dielectric layer has a substantially square shape.
[0014]
The electrode layers of the individual electrodes are connected to one another in a manner known per se by a scoop layer 2 extending transversely thereto. FIGS. 1 and 3 show that the scoop layer 2 is arranged on the end faces of the component 1 that are separated from each other.
[0015]
Each scoop layer 2 is provided with one electrical connection contact 3, which is connected to the scoop layer 2 by a welding point 4. The connection contacts 3 are preferably made of a metal material and can be made, for example, from a metal sheet using a stamping process.
[0016]
The connection wires, cables, etc., each have two fork-shaped cut / clamp contacts 5 in order to cut / clamp and connect the connection contacts 3 to another wired electrical component without soldering. As can be seen from FIG. 2, the cut-clamp contact 5 has two fork arms 6, each of which is separated from one another by a slit, which fork arm tapers towards its free end. The fork arms 6 have cutting edges on the inside facing each other. The distance between the fork arms 6 is selected to be smaller than the size of the wire or the like sandwiched between them. As a result, when the wire or the like is sandwiched between the fork arms 6, it is securely clamped. The electrical component 1 can thus be easily connected to other electrical components, connecting wires and the like into one compact circuit configuration.
[0017]
FIGS. 2 and 3 show that the cut-clamp contacts 5 are arranged substantially parallel to one another with their extension direction, and that their free ends also point in the same direction. Thus, the entire cut-clamp contact 5 can be connected simultaneously with a connection wire such as another electrical component by applying a mechanical pressure to the back surface of the component opposite to the cut-clamp contact 5. In order to keep the mechanical load on the layer staples of the component 1 as low as possible during the press-fitting of the cut-clamp contacts 5, the connecting contacts 3 form a fitting aid 7 at the end remote from the cut-clamp contacts. Are angled toward different connection contacts 4. The pressing force required for press-fitting the cut-and-clamp contact 5 is guided directly to the connection contact via the fitting aid 7.
[0018]
As can be seen from FIG. 2, the connection contacts 3 each have two cut-and-clamp contacts 5 laterally spaced from one another. These are arranged with their extension surfaces parallel to the scoop layer 2 and are integrally interconnected at their fixed ends by a transverse web 8. Here, the connection contact 3 is configured in an H-shape with two longitudinal legs interconnected by a transverse web 8. The longitudinal legs have one leg 9, 10 on each side of the transverse web 8. Among them, the leg 9 is connected to the scoop layer 2 and the leg 10 has the cut-clamp contact 5.
[0019]
FIGS. 1 to 3 further show that the component 1 is symmetric with respect to the center plane 11 and the center line 12.
[0020]
The electrical component 1 embodied as a capacitor has an electrical connection contact 3 which has a fork-shaped cut-clamp contact 5 for solder-less cut-clamp connection wiring. The electrical component 1 can thus easily be formed and connected to the wired electrical components in an electrical circuit.
