Definitions

  • the invention relates to a dust-protected electrical contact, the live parts of which are arranged in a closed housing.
  • Such dust-protected contacts have hitherto become known in the form of the so-called reed relays, which consist of a cylindrical glass housing, in the wall of which two or more contact tongues, which are superimposed with their contact ends at the distance from the switching stroke, are melted and actuated by the magnetic field of a solenoid become.
  • a disadvantage of these contacts is, on the one hand, the extremely high sensitivity of the glass housing at the melting points, which has the consequence that rib formation can often be observed there as a result of low external impact forces.
  • Another disadvantage of this contact is the low switching capacity, which results from the low switching stroke that can be managed by the electromagnetic field acting directly on the contact blades.
  • the invention has for its object to provide an electrical contact of the type described, the housing is insensitive to rough treatment during transport and with the much larger currents than can be switched.

  • the housing sections to be deformed for making contact are expediently made of plastic.
  • a contact according to the invention Since the housing of the contact, which is now no longer made of glass, is now largely insensitive to impacts and vibrations as well as temperature differences, a contact according to the invention always remains protected against dust even under rough operating conditions. Another important advantage of a contact according to the invention results from the possibility, instead of the previously usual contact actuation by direct field action on the contact tongues, now deforming the housing by mechanical action thereon and thereby producing the switching stroke of the contact. The occurring elastic bracing of the housing provides the restoring force of the contact after the actuating force has been released.

Likewise, the deformation of the contact housing can also be carried out by means of a plunger which is moved in a purely translatory manner, for example the plunger of a hand-operated key or the iron core of a magnetic coil.
  • such a resilient housing is provided, which the two housing sections, in which one or more contact tongues are arranged under the action of an external actuating force, perform a relative movement with respect to one another in which the contact tongues participate, which after the actuating force has been canceled out the action of the restoring force of the housing return to the starting position.
  • the housing is provided with one or more notches, which bring about a local reduction in the bending resistance moment of this housing, as a result of which the position of the bending point of the housing and the size of the required bending force and the resulting restoring force and the size of the contact force are defined.

Abstract

Le contact electrique est constitue par un boitier (1) entierement ou en partie deformable elastiquement, dans les parois duquel sont inserees, de maniere etanche a la poussiere, au moins deux lames de contact (2, 3). Les surfaces de contact (4) des lames sont placees vis-a-vis et entrent en contact lors d'une deformation appropriee du boitier, par exemple lorsque le boitier est incurve dans son plan longitudinal. Des que la force d'actionnement (F) cesse, le boitier revient dans sa position de repos sous l'effet de ses proprietes elastiques et les surfaces de contact sont ecartees l'une de l'autre. Le nombre de points de contact, la section de droite du boitier, le materiau du boitier, le mecanisme d'actionnement et le sens de deformation peuvent etre choisis dans une plage tres large.
