摘要： In order to provide a method for isolating a circuit and a thermal link, wherein the link has a very low resistance and is suitable for high currents, in particular very high short load currents, and also has a high degree of reliability, in particular under difficult conditions, such as thermal and mechanical loading which lasts for a relatively long time, for example, the invention proposes that, during the phase transition of the material of the fusible element (10) from the solid to the liquid state, the volume of the fusible element (10) increases and the pressure increases and, owing to the increase in volume and the increase in pressure, the fusible element (10) is dislodged so as to break the electrical connection.

摘要： The protective element includes an elastic member firmly adhered through a solder to second conductor layers and current-carrying electrode terminals formed on a prescribed substrate in such a manner to divide a current-carrying path in plural to form an electric current interruption portion. The solder has a liquid-phase point higher than a mounting temperature at which the protective element is mounted to a protection target device. The elastic member is soldered onto the second conductor layers and the current-carrying electrode terminals in a state that the elastic member maintains a level of stress allowing at least one of the current-carrying electrode terminals among the second conductor layers and the current-carrying electrode terminals to be separated from the elastic member by deformation of the solder even in a case where the solder is not completely melted.

摘要： The fuse assembly contains a first casing member with a first chamber, and a second casing member with a second chamber. An enclosed space is thereby formed by joining the first and second casing members together. A disconnection member is sandwiched between the first and second casing members. The disconnection member contains two electrodes and a fuse element between the two electrodes. Each electrode contains a first lateral section, a vertical section, and a second lateral section, jointly and integrally forming a C-like shape. The electrodes are positioned at two opposing ends of the second casing member and the fuse element is housed in the enclosed space. The enclosed space allows the fuse element to break off completely, thereby avoiding electrical arc and achieving enhanced usage safety.

摘要： In one aspect of the present invention, subminiature fuses are soldered to a PCB via clips attached to the fuse end caps. The clips are physically attached to the PCB pads, enabling the fuse to be replaced if needed and providing thermal decoupling between the fuse and the heating sinking solder/PCB pads. The fuse and clips can also be picked and placed in one operation. In another aspect, improved fuse clips are provided that include tabs that separate the housing portions of the clips from the heating sinking solder/PCB pads. Such improved clips further enhance thermal decoupling. In a further aspect, an improved fuse is provided, in which the thermal decoupling tabs just described are provided directly with the fuse. In yet a further aspect, a thermally insultive fuse body is provided to further decouple the fuse element from its surroundings.

摘要： In order to produce a cost-effective fuse (100) in chip design, which is applied to a carrier substrate (10) made of a Al2O3 ceramic having a high thermal conductivity, and which is provided with a fusible metallic conductor (13) and a cover layer (14), in which the melting point of the metallic conductor (13) may be defined reliably, it is suggested that an intermediate layer (11) having low thermal conductivity be positioned between the carrier substrate (10) and the metallic conductor (13), the intermediate layer (11) being formed by a low-melting-point inorganic glass paste applied in the screen-printing method or an organic intermediate layer (11) applied in island printing. Furthermore, a method for manufacturing the fuse (100) is specified.
