Title: Spark-free electric switching device - allows switching in high temperature range by relay control and electronic control in front of load
Inventor: BALLES WOLFRAM
IPC: H01H9/56
Filed: 1992-08-12
Abstract: The switch device switches electrically operated devices in high temp. ranges. An electronic control (I, II) and a relay control (R1, R2) are connected in parallel to each other in front of the electric load to be switched. The relay control (R1, R2) is activated by the switching on or off of the electronic control (I, II) as the phases (A, B, C) of the mains current pass through the null point. For switching an ohmic load, a null voltage switch is used as the electronic control (I, II). For switching an inductive or capacitive load, an electronic control (I, II) with a duty cycle adjustable with phase-shift of the current null point relative to the voltage null point is used. USE/ADVANTAGE - Esp. for use in aircraft, at temps. above 85 deg.C. Allows reliable operation at high temps.
Patent DE-4228490-A1 (DE)
Inventor: FRECH FRIDOLIN ALOIS
IPC: H01R13/645
Filed: 1992-08-27
Abstract: The plug connector system (S) for multipole electrical plugs (40) is used for coding to prevent undesired insertion into a plug socket which it fits, which makes it possible to use identical plug connector designs for multiple purposes. With respect to the external dimensions of the plug (40) and plug-socket insert (14), the plug connector system (S) is constructed in a common, standardised manner for specific numbers of poles. The coding system (26) and the contact system (48) of the socket and plug (40) are physically separated in the insertion direction (R) and are independent of one another. The plug connector system (S) is used for electrical connections to main and peripheral communications apparatuses, for example ISDN, telephone, terminal and modem as well as PC and host computer. <IMAGE>
