    摘要： A circuit for the surveillance of the switching state of a power transistor is constructed such that both, the voltage applied to the power transistor (1) is surveyed by way of a voltage comparator (7), as well as the voltage applied to the load (3) is surveyed by way of a further voltage comparator (8). The comparator (7) in the switched-on state and the comparator (8) in the switched-off state are activated by the input signal (U.sub.IN) of the power transistor (1). The output signals of the two comparators (7, 8) are combined to a status signal (U.sub.Stat). It is possible by way of the proposed circuit to recognize both a short circuit or, respectively, a shunt circuit of the load as well as a leakage current of the power transistor (1) and thus an interruption of the load occurs.

    摘要： A housing for electric componentry comprises a closed frame in which the electric componentry is received, a first electric connection element which is connected to the electric componentry and passes through a wall of the frame, a second electric connection element which is connected to the first electric connection element, and an electric connection cable which is connected to the second electric connection element. A fastening element fastens the electric connection cable to the frame of the housing in such manner that the cable lies parallel to a flat outer surface of the frame. At least a part of the fastening element is constructed integrally with the housing. In a preferred embodiment, the housing further comprises a cover attached by a hinge to the frame. Further, the fastening element comprises first and second parts which bear upon each other with the electric connection cable therebetween. One of the parts of the fastening element is integral with the cover, so that the electric connection cable is fastened to the housing in proper fashion merely by closing the cover of the housing.

    摘要： A housing for an electrical component which protects the electrical component sealed therein and reduces mechanical stress on the electrical component includes two housing sections which are connected to each other, a support for the electrical component located within the housing, and attachment connections for mounting the housing on a mounting point, e.g., of a motor vehicle chassis. To reduce the mechanical stress imposed upon the electrical component, and to obtain a good seal of the housing interior against dirt, etc., the two housing sections are connected to each other directly or via an intermediate piece. The housing interior is sealed by one or two seals, made from elastically or plastically deformable material, which are located between the faces of the support and the housing sections associated with them. The attachment connections are located on one of the two housing sections.

    摘要： A safeguard feature prevents supply of voltage to an electrical device in the event a protective element is no longer reliably connected in a circuit arrangement for protecting a susceptible component from inadmissible voltage values. The protective element in the circuit arrangement is often conveniently provided in the form of a suppressor diode, which is connected in parallel with the susceptible component to be protected, and which experiences breakdown in case of excessive voltage, thereby causing a short-circuit in the power supply. In the event of such protective response, the suppressor diode may heat up considerably, and that the solder used for electrical and mechanical attachment may liquefy or evaporate. As a result the suppressor diode may become completely or partially unsoldered, so that a reliable protection of the susceptible component is no longer ensured by the shorting of the circuit thereacross. At least one of the conductors going from the power supply system to the protected component is therefore provided with a break location, and one of the connections of the suppressor diode bridges the break location prior to breakdown. If the suppressor diode then becomes unsoldered or otherwise detached from the rest of the protection circuit, the susceptible component is nevertheless protected from the inadmissible voltage since it is isolated therefrom by the discontinuity in the conductor provided by a separation therebetween defined by the break location.

    摘要翻译： 在保护元件不再可靠地连接在用于保护敏感元件不被允许的电压值的电路装置中的情况下，保护功能可防止向电气设备提供电压。 电路装置中的保护元件通常以抑制二极管的形式方便地设置，抑制二极管与易受保护的部件并联连接，并且在过电压的情况下经历击穿，从而导致短路 电源。 在这种保护性反应的情况下，抑制二极管可以显着加热，并且用于电和机械附着的焊料可能会液化或蒸发。 结果，抑制二极管可能变得完全或部分未被起动，从而通过其周围的电路的短路不再能够确保敏感部件的可靠保护。 因此，从电源系统到受保护部件的导体中的至少一个设置有断路位置，并且抑制二极管的连接之一在击穿之前桥接断开位置。 如果抑制二极管然后变得未被保护或者与保护电路的其余部分分离，则易受影响的部件仍被保护以免受不允许的电压，因为它由于由断路位置限定的间隔提供的导体中的不连续性而被隔离。
