例が決して稀ではないのである。 Known safety devices of this type are already fitted at the factory with individual fuses, which are clamped and held between the contacts of each conductor of the current circuit. Particularly in motor vehicles, it is necessary to safely interrupt a large number of current circuits, and therefore each vehicle is equipped with a relatively large number of fuses, which are arranged side by side in a row at intervals. ing. The disadvantage of such safety devices is that they are expensive. This means that the fuse must be manufactured as an individual component in a separate processing or working step, which requires additional manufacturing equipment. A further disadvantage is that the individual fuses must be clamped between the contacts of the conductor in a separate working step, which requires high installation costs. In addition, the electrical contact between the fuse and the conductor contacts is highly variable, especially after long-term use, due to construction conditions and dependence on clamping or clamping spring forces. There is a possibility that the variation range of the electrical contact connection will be large and the characteristics of the fuse will be adversely affected. For example, a bad electrical contact inevitably results in a high voltage drop, which can cause considerable heating at the fuse and its surroundings. Such heating can lead to failures at the fuse location, in which case the operating function is adversely affected and additional repairs are required. In this way, the use of separate individual fuses that are clamped or clamped not only significantly reduces technical reliability, but also
The cost will be extremely high. In connection with this, it must be taken into account that in practice, due to the current strict standards for electrical equipment, fuses for interrupting current circuits only work very rarely. Therefore, for example in a motor vehicle,
It is not uncommon for a single fuse to not need to be replaced during a vehicle's entire operating life of approximately 10 to 15 years.

That is, the safety device according to the invention should be easy to manufacture and install, require no additional components, and reduce costs. Furthermore, it must be possible to accommodate the plug-in fuse when required after its installation and to maintain its electrical contact reliably and permanently, thereby increasing safety.

The invention is solved by covering the central electrical device, and in addition, in the cover of the central electrical device, one observation opening is formed for each individual molten conductor.

み、別個のヒユーズを使用すればよい訳である。 The advantage of the invention is that the fuses of the current circuit can be manufactured in a single processing step at the same time as the conductor is manufactured, which eliminates the need for additional production equipment for the fuses as well as additional installation operations and is therefore costly. The point is that it can save a considerable amount of money. Particularly in safety devices installed in motor vehicles where the conductor is formed as a flat rectangular strip, the molten conductor can be punched from one material simultaneously with the conductor in the same processing or work step. . Another advantage is that a completely satisfactory mechanically and electrically excellent electrical contact connection is obtained between the conductor or its contacts and the molten conductor. Due to the integral construction described above, a completely fixed connection is achieved with almost no vibration or loosening, and therefore always permanently reliable over a long period of use, even over several years. This is because a good contact connection is guaranteed. In this way, heating due to unacceptable voltage drops due to deterioration of the contact connections is completely avoided, failures resulting therefrom are also excluded, and high operational reliability is achieved. If a fault occurs in the electrical circuit and the molten conductor operates and blows out, forcing the current circuit to break, after removing the fault in the current circuit, it is preferable to install a commercially available fuse between the contacts of the conductor. to make the current circuit operational again. Therefore, according to the present invention, a separate fuse is required only if the molten conductor, which has already been formed integrally with the conductor in the factory or manufacturing facility, burns out in the event of a fault (which occurs very rarely). It's fine if you use it.
