Terminating and connecting device

Abstract: A terminating and connecting device with a housing having a lower and upper housing parts, at least one contact spring for electrically contacting at least one terminal lead, at least one terminal element for connecting at least one cable, and at least one metal part for connecting the contact spring to a cable connected by the terminal element. The housing upper part has at least one actuating element and a contact spring. The contact spring has two contact legs connected by a back, and the lower housing part has a top spring has two spring legs and a back which connects the spring legs. When the housing upper part is pressed onto the housing lower part, the actuating element presses on the back of the top spring so that the top spring moves into a position such that the terminal lead is clamped between the contact legs.

Anschlussklemme für Leiterplatten

Abstract: Die vorliegende Erfindung bezieht sich allgemein auf das Gebiet grundlegender elektrisch leitender baulicher Vereinigungen. Bauliche Vereinigungen einer Vielzahl von gegenseitigen isolierten Verbindungselementen, besonders ausgebildet fur gedruckte Schaltungen, wobei die bauliche Vereinigung ein Bauteil einer elektrischen Verbindung zwischen zwei oder mehreren leitenden Gliedern mit direktem Kontakt unter Verwendung einer Feder darstellt. Eine solche Verbindung, insbesondere aus dem Bereich der Klemmen, stellt die elektrische Anschlussklemme dar. Die Anschlussklemme dient als Bindeglied in der Leiterplattenanschlusstechnik zu zuverlassigen Versorgung der industriellen Elektronik und wirtschaftlichen Einzelverdrahtung auf gedruckten Schaltungen. Bei der erfindungsgemasen Ausgestaltung des Kontakteinsatzes einer Anschlussklemme mit symmetrischer Lagerung des Federkraftelements, dem erfindungsgemas gestalteten Federkraftelement mit einfacher Schnittgeometrie und deren einfachen Montage bei der vorteilhaften Verbindung mit dem Kontakteinsatz, entsteht ein geschlossener Klemmkafig, wodurch es ermoglicht wird, die Bauhohe des Isolierstoffgehauses entscheidend zu reduzieren.

New spark-gap technology with efficient line-follow current suppression for the protection of powerful LV distribution systems

Abstract: The electrical properties of low-voltage power systems (LVPS) can have a strong effect on the operational behavior of surge protective devices (SPDs) to be used for protection purposes. Besides the right selection, the qualification-testing of SPDs connected these systems has to be carried out under test conditions which meet the real operating conditions of the power systems in which these SPDs should be installed. In this regard, the “class I and Π operating duty tests” according to IEC 61643-11, chapter 8.3.4.3 is an essential test for the qualification of SPDs connected to LVPS. In this test the SPD is stressed with defined surge-current impulses while it is connected to a power system simulating the characteristic of the real LVPS in which the SPD should be installed. The focus of the work presented is laid on class I SPD based on a newly developed “line-follow current free” spark-gap technology. Fundamental aspects, like basic functional principles, construction details, the performance and also the advantages of this new class I SPD technology are presented and discussed in detail. A special focus is set on the performance of this technology in case of use in powerful LVPS with short-circuit currents up to 100 kA rms.

Plug-in jumper for electrical junction and/or connecting terminals and electrical junction and/or connecting terminal

Abstract: A plug-in jumper for terminal blocks is provided for elastic engagement in openings in busbars and for electrical contact-making of the busbars of at least two junction and/or connecting terminals. The plug-in jumper includes a jumper bar having a bar strip and several plugs which are connected to the bar strip. Each plug has at least two contact legs located essentially parallel to one another, of which at least one is made elastic. The plug-in jumper makes it possible to electrically interconnect different busbars of different terminal blocks since the plugs have two contact areas which are located on top of one another for contact-making of two busbars of two junction and/or connecting terminals which are located next to one another, wherein the two busbars are located on a different planes.

Method and system for creating and checking the validity of device certificates

Abstract: In order to easily identify an invalid device certificate by means of a validity check when signing keys that are used to create device certificates are compromised, the invention proposes providing a piece of state information for device certificates that comprises positive evidence of the existence and validity of the device certificate, and alternatively or additionally applying a special validity model for device certificates, wherein the time of issue of the device certificate is documented by means of a signed electronic timestamp, wherein a different signing key is used for signing the timestamp than for signing the device certificate. A further aspect of the invention involves all information that is required for the validity check on a device certificate being stored in a memory of the device or in a memory associated with the device, so that an identity check on the device can be performed at any time without fetching additional data, i.e. an offline check on the stored device certificate is made possible.
