description

The invention relates to a capacitor; it relates in particular to a built-in interference suppression capacitor for alternators, hereinafter referred to as generator, and above all a capacitor for radio interference suppression and safeguarding the electromagnetic Compatibility.

It is known to use interference suppression capacitors for generators with rectifiers that are mounted, for example, from the outside will.

Here, the capacitor has a lead whose inductance ensures the interference suppression of the capacitor Resonance phenomena and lowering the upper limit frequency of 3 limits. Additional connection elements for the supply line are also required. In addition, there is a separate insulating bushing when mounting the rectifier in the generator necessary.

The invention is based on the object of providing an interference suppression capacitor, in particular for installation in generators, which bypassing the at the booth of Technology shown disadvantages can be built into the generators.

This object is achieved by the capacitor according to claim

1 solved. Further advantageous embodiments of the invention Device emerge from the following claims

2 to 4. The invention will be explained in more detail with reference to FIGS. 1 to 3 explained.

Fig. 1 is a vertical section through an inventive Embodiment;

Fig. 2 is a vertical cross section around the embodiment according to FIG. 1, which has been rotated by 90 °;

Fig. 3 is a schematic cross section through an inventive, Interference suppression capacitor built into a generator.

According to FIGS. 1 and 2, there is the inventive
Capacitor from a capacitor element 4, which preferably has a polycarbonate dielectric. This capacitor is
preferably completely encapsulated with a plastic 5,
polyamides in particular are suitable.

The capacitor element. 4 has two tab-shaped connections on the capacitor plates,
which are designed in the form of a band and are arranged on the opposite sides of an insert part 3 made of plastic, which is for example rectangular. This insert 3 is preferably integrated into the extrusion coating 5. In the insert 3, a passage 6 is formed, which also passes through the connection lugs 1 and 2, the passage 6
on one side of the insert 3 continues in a tubular shape. In this way, an insulating bushing 6 integrated in an interference suppression capacitor is made available. This insulating socket 6, which is provided with an interference suppression capacitor, can be used wherever two components are to be mechanically connected to one another and have a potential against one another, and at the same time these two components are to be electrically isolated from one another via an insulating body 7. Since the capacitor tab 1 is not insulated in the area of the exit of the insulating bushing 6, a metal screw passed through the bushing 6 rests with its head in an electrically conductive connection on the tab 1. Accordingly, the tab 2 is not insulated in the area of the socket 6, so that it is designed for electrical contact in this area. According to FIG. 3, in the case of a special generator, this area rests on the plus-side heat sink 8, while the minus-side heat sink 9 is connected to the capacitor bracket via the screw 10.

The capacitor of the invention is particularly
suitable for installation in a generator; the simple compact execution of the capacitor according to the invention without

Connecting lines or connecting elements reduce the cost of materials and assembly time considerably.
