摘要:
Gegenstand der Erfindung ist eine thermische Überlastschutzanordnung (40) zum Schutz eines auf einer Trägereinrichtung (10) mit Stromführungselementen (14, 16) angeordneten elektrischen Bauelements (12), insbesondere elektronischen Bauelements, wobei die Überlastschutzanordnung (40) mehrere, je eines der Stromführungselemente (14, 16) mit einem zugehörigen Anschluss (22, 24) eines elektrischen Bauteils elektrisch kontaktierende und bei Überlast des Bauelements (12) schmelzende Lotverbindungen (18, 20) und eine Abtrennvorrichtung (30) zum Lösen mindestens einer dieser Verbindungen (18, 20) aufweist. Erfindungsgemäß ist vorgesehen, dass das Bauteil das Bauelement (12) ist oder zumindest aufweist und die Abtrennvorrichtung (30) eine das Bauelement (12) gegenüber der Trägereinrichtung (10) zumindest bei Erwärmung vorspannende Abtrennvorrichtung zur räumlichen Separation des Bauelements (12) von mindestens einem der Stromführungselemente (14, 16) ist, die bei Aufschmelzen der Lotverbindungen (18, 20) auslöst. Die Erfindung betrifft weiterhin ein entsprechendes Verfahren zum Schutz eines Bauelements (12).
摘要:
Disclosed herein is a battery pack including a battery cell having an electrode assembly of a cathode/separator/anode structure mounted in a battery case together with an electrolyte in a sealed state, and a protection circuit module (PCM) electrically connected to the battery cell, wherein the PCM is provided with a safety device of which a circuit is cut off when temperature is high or a large amount of current flows.
摘要:
The invention relates to an electronic assembly (1) which comprises a printed circuit (2), provided with strip conductors (6) and equipped with a plurality of SMD components (4) and/or additional electronic and/or electromechanical components using a suitable solder, thereby forming an electronic circuit. The aim of the invention is to ensure by simple means that power dissipation of such an electronic assembly is reduced. For this purpose, a plurality of connections is established between strip conductors (6), components and/or component parts via respective spring-loaded contact bridges (12, 12', 12'', 12''').
摘要:
A printed-circuit board includes an insulating substrate (20) with wiring patterns (12), and a fuse (6) on the substrate (20). One end of the fuse (6) is connected directly to a first pad (12a) of one wiring pattern (12), whereas the other end of the fuse (6) is connected directly to a second pad (12b) of another wiring pattern (12). The fuse (6) is covered with a protective material (7).
摘要:
The invention relates to an electric or electronic appliance which is provided with a weakened conductor area (burning area 7) for protecting against failures that are caused by extreme power consumption. Said area at least partially carries a non-conductive coating (8, 9) that serves for arc extinguishing. The coating can be provided with arc-extinguishing substances if required.
摘要:
The invention relates to a self-resetting thermal release, comprising a flat thermostatic bimetal snap element (1, 9), said snap element being fixed on the circuit substrate with high-melting solder by at least one soldered junction and being thermally coupled with said circuit substrate. Said soldered junction is configured as a first contact point (5) for connection to a corresponding circuit contact of the circuit substrate (4). The snap element (1, 9) is mechanically pre-cambered into an arch-shape in such a way that when the release is not activated, it is in electroconductive contact with a second contact point (6) of the circuit substrate (4). When the release is triggered, the camber of the arch is reversed, and so the snap element no longer comes into contact with said second contact point (6).
摘要:
The thermal cut-out consists of a strip-like leaf spring (1) with contact points (5, 6) at the ends for connection to corresponding circuit contacts (21, 22) on the substrate (20). The leaf spring (1) has a spring arm (4) as a connector between the contact points with a roof-shaped deformation (7) and a spring section (13) connecting thereto. After the leaf spring (1) has been soldered to the circuit contacts (21, 22), pressure distortion of the roof-shaped deformation (7) produces a prestress in the spring arm (4). The thermal cut-out is suitable for circuits in general and especially for film circuits.
摘要:
Die Erfindung betrifft eine elektrische Baugruppe (1) mit einer Sensorik (10) und ein Verfahren zum Steuern einer elektrischen Baugruppe (1). Dabei werden mittels eines Steuergerätes von der Sensorik (10) bereitgestellte Messdaten, welche eine thermomechanische Eigenschaft der Baugruppe (1) charakterisieren, empfangen und zu einem Steuersignal für wenigstens ein aktives Beeinflussungselement (17) der Baugruppe (1) verarbeitet. Mittels des wenigstens einen aktiven Beeinflussungselements (17) wird durch aktive Beeinflussung wenigstens eines Bauelementes (2, 3, 4, 5, 6, 7, 9) der Baugruppe (1) in Abhängigkeit von dem Steuersignal die thermomechanische Eigenschaft beeinflusst und dadurch ein Ausdehnungsunterschied zwischen wenigstens zwei Bauelementen (2, 3, 4, 5, 6, 7, 9) der Baugruppe (1) minimiert.
摘要:
A thin film fuse is formed by two substantially planar conductors, separated from each other by a thin gap. The conductors and gap are over-coated with a thin, conductive material having a surface tension when melted, great enough to pull the conductive material out of the gap.
