Abstract: A holder is provided for a cylindrical electrical safety fuse having conductive end caps. A hollow housing receives the fuse therein through a front side which is closeable with a closure cap. A compression spring at a back end of the housing biases the fuse against a conductive metal inner cap disposed interiorly of the end cap. The inner cap has a radially extending contact tab. A terminal pin is provided to conductively engage the contact tab. The terminal pin has a contact portion with a perpendicularly-extending base, a cantilevered front leg extending from and overlying the base, and a cantilevered spring leg extending from a second end of the base so that the spring leg is disposed intermediately between the front leg and the base and also overlies the base. A clamp slot is defined between the front leg and the spring leg to form an electrical contact with the contact tab.

Abstract: A multimeter comprising a clip-on device (12) and a Hall-effect measuring circuit (5) for measuring either a direct or an alternating current I. Moreover, the multimeter comprises a voltage-measuring circuit (2) for measuring either a d.c. or an a.c. voltage U as applied to two input/output combination sockets (3, 4). By means of a function transformer (30), a digitizing unit (19), a digital unit (25) and further circuit components which also include a battery-operated power-supply unit (1), the measured current and/or voltage values, by taking into due consideration any stored correcting values as well as such correcting values which result from adjusting measurements, and any circuit-specific constants as already previously stored by the manufacturer, are processed in accordance with predetermined rules for proportioning into display signal-waveform-independent values relating to the current I, the voltage U, the apparent power Ps, the real power Pw, the power factor, the frequency f, and further values.

Abstract: A heat dissipating housing (1, 4, 5, 6) with a tub (1, 4) and an outer cover (5, 6) seated on the tub (1, 4)--preferably hermetically tight--for an electronic circuit component (11, 17) which in operation gives off heat to be dissipated such as a light emitting diode (17) and/or a semiconductor driver chip (11) is disclosed. The circuit component (11, 17) is fastened on the bottom (1) of the tub (1, 4). In operation, the heat to be dissipated is to be transferred at least in considerable part via a heat removal body (5, 6) of the housing (1, 4, 5, 6) to an outer surface of the housing, preferably via a heat conducting outer cover (5, 6) serving as the heat removal body (5, 6) to the outer surface air, sweeping the housing.

Abstract: A housing for an optoelectronic circuit module useful in a glass fiber communications system including a luminous flux suspended into the housing. The flux is conducted in a vacuum or a gas, between first and second mutually positioned optical components. The first optical component is attached to the housing via a first support, and a second optical component is attached to the housing via a second support. The first support is installed in one of the housing walls or inside the housing and the second support is rigidly attached to an interior section of the housing. In operation, at least the second support is subjected to large temperature variations of e.g., between -40.degree. C. and +130.degree. C. At least the interior section of the housing which is adjacent to the second support is comprised of a first weldable material and has a first linear thermal expansion coefficient.
