Embodiment Construction

[0055] Figure 1a A simplified cross-sectional view of a first embodiment of a detection device 10 is shown, for example a power Zener diode, referred to simply as a diode in the following. The testing device 10 has a base element 12 with a receptacle 8 . The receptacle 8 has a pot shape, wherein other shapes are also conceivable. Semiconductor components 18 are arranged on the pot-shaped bottom. As can be seen from FIG. 1 , the semiconductor element 18 is directly connected to the socket element 12 . The semiconductor element 18 may be made of silicon. It can have a pn junction as a barrier. The socket element 12 can be made of non-ferrous metal, preferably copper or other non-ferrous metal. However, other materials can also be used for these elements 12 , 18 .

[0056] The header element 16 made of electrically conductive material is in turn arranged directly on the semiconductor element 18 . The head element 16 is electrically connected to the base element 12 only via...

Abstract

The invention relates to a polarity reversal protection unit for motor vehicles. Said unit has a detector unit (10), a first connection element (22) that is electrically connected to a supply supporting structure (94) and a second connection element (24) that is electrically connected to the potential of the vehicle body. In the event of a polarity reversal, the first connection element (22) is electrically connected to the second connection element (24) by means of a detector unit (10). In addition, the polarity reversal unit is characterised in that an insulating layer (26) is provided between the first connection element (22) and the second connection element (24), each of the connection elements (22, 24) has at least one receptacle (36, 38) and the detector unit (10) is located in a form-fit in at least one receptacle (36, 38).

Description

technical field [0001] The present application generally relates to a reverse polarity protection device for automobiles, which has a detection device, a first connection element electrically connected to the power supply base, a second connection element at the potential of the vehicle body, wherein, in polarity In the case of reverse connection, the first connection element is electrically connected to the second connection element through the detection device. The present application also relates to a power supply base with such a reverse polarity protection device and a method for preventing polarity reversal of an on-vehicle power grid. Background technique [0002] Today's automotive on-board power grid is increasingly used and has several different loads. The load is generally powered by the car battery. Many of these loads are sensitive to polarity reversal. Examples of such situations are semiconductor non-contact switches or electrolytic capacitors, which can be...
