Abstract:
With a temperature-dependent switch, a temperature-dependent switching mechanism is accommodated in a housing and, depending on its temperature, establishes an electrical connection between at least two connection electrodes provided on the outside of the housing. The housing has a lower part and a cover part, closing the latter while forming at least one join, with an adhesive layer stamped on in the region of the join and sealing the join. A process for producing a temperature-dependent switch sealed in this way is likewise described.
Abstract:
A temperature-dependent switch comprises a housing having a lower housing part and a cover part capping said lower housing part. A first countercontact is provided at an inner surface of said cover part, said first countercontact having a projection pointing into said housing. A second countercontact is provided at an inner surface of said lower housing part. Inside of said housing a temperature-dependent switching mechanism is arranged, said mechanism including an electrically conductive spring element having an opening. Dependent on the temperature said spring element assumes at least two distinct switching positions, whereby in its first switching position the spring element is in contact with both said first and second countercontacts, thereby electrically interconnecting said first and second countercontacts. At least when said spring element is in its first switching position, said projection at said first countercontact protrudes into said opening in said spring element, thereby centering the latter in the housing.
Abstract:
A Method of Manufacturing a Shrink-On Cap In a method for manufacturing a shrink-on cap (10'), first of all heat-shrink tubing sections (27) having an opening at each of their two ends (14, 17) are prepared. The heat-shrink tubing section (27) is then pressed together at its end (17), producing a welded seam which constitutes a rim (16) and closes off the corresponding opening. The rim (16) lies substantially in a plane of symmetry of the heat-shrink tubing section (27). The rim (16) is then deformed in such a way that its sharp edge (18) and pointed corners are removed from the plane of symmetry. A method for protecting an electrical component by means of a shrink-on cap (10') produced this way is also described.
Abstract:
A temperature controller comprises a bimetallic switching mechanism that switches in response to a predetermined temperature, a lower housing part receiving the switching mechanism, a cover part closing off the lower housing part, and a substantially inert film that is arranged between the lower housing part and the cover part. The substantially inert film comprises a polyimide. The film comprises a mechanical seal between the lower housing part and the cover part.
Abstract:
A temperature controller (10) having bimetallic switching device (15) which switches at an excess temperature and a heating resistor (23) in the same circuit as this which has the effect of a self-locking function. The heating resistor (23) is designed on a film (22) which is provided for thermal and/or electrical insulation.
Abstract:
An electrical load, such as a motor, has a first and a second terminal element for supplying electricity to the load. The second terminal element is directly connected to the load whereas the first terminal element together with a further terminal element forms a clamping socket for a switching device. The further terminal element is electrically connected to the load. When the switching device is inserted into the seat, the first terminal element is connected to the load in series with the further terminal element via the switching device.
Abstract:
A switch comprises a first and a second external terminal as well as a temperature-dependent switching mechanism that creates, as a function of its temperature, an electrically conductive connection between the two external terminals for an electrical current to be conducted through the switch. The switching mechanism comprises a switching member which changes its geometrical shape between a closed position and an open position as a function of temperature and, in its closed position, carries the current flowing through the switch. The switching mechanism further comprises a spring element which is permanently connected electrically and mechanically in series with the switching member. The displacing force of the spring element is substantially temperature-independent, the switching member having a temperature-dependent displacing force which, in its creep phase, is greater than the displacing force of the spring element.
Abstract:
A switch is described, having a housing 12 which receives a temperature-dependent switching mechanism 11 and which has a first housing part 15 on whose inner base 25 a first electrode 24 connected to a first external terminal 23 is arranged, as well as a second housing part 14, closing off the first housing part 15, that comprises a second electrode 20 connected to a second external terminal 22. The switching mechanism 11 creates, as a function of its temperature, an electrically conducting connection between the first and the second electrode 24, 20. A series resistor 34 is arranged in the housing 12, geometrically and electrically between the switching mechanism 11 and one of the two electrodes 20, 24.
Abstract:
A temperature-dependent switch has first and second external terminals arranged at an electrically conductive lower housing part and an insulating cover part, respectively. Within said lower housing part there is arranged a temperature-dependent switching mechanism having a bimetallic snap disk and an electrically conductive spring disk carrying a movable contact element that is configured integrally with and as a dome on the spring element. Depending on the temperature of said bimetallic snap disk said spring element is in electrical contact with said first terminal and via said movable contact element with said second terminal.
Abstract:
A switch having a housing which receives a temperature-dependent switching mechanism is described, the housing having an electrically conductive lower part as well as an electrically insulating cover part, closing off the lower part and attached thereto, on whose inner side a first countercontact, to which through contact is made externally, is provided for the switching mechanism. The lower part serves as the second countercontact of the switching mechanism and creates, as a function of its temperature, an electrically conductive connection between the two countercontacts. Arranged on the cover part in lossproof fashion are a first connection electrode that is connected electrically to the first countercontact, as well as a second connection electrode that is electrically connected to the lower part as a consequence of the attachment of the cover part to the lower part.
