Definitions

  • the invention relates to a contact assembly for at least one contact bolt of a contactor.
  • the invention further relates to an electrical assembly with a contactor with two contact bolts.
  • Such contact assemblies are used to tap off the voltage, for example.
  • a contact element is introduced between the contactor and the power consumer.
  • this has the disadvantage that a transition resistance occurs twice here, as a result of which the total resistance increases.
  • the problem of the invention is to provide a solution in which the total resistance is low.
  • a contact assembly for at least one contact bolt of a contactor comprising a contact element with a base part extending in a plane, the base part having an opening for the contact bolt to pass through, and at least one contacting tab that is integrally connected to the base part and located at the edge of the contact opening, the contacting tab being bent out of the plane of the base part and being elastically deflectable parallel to the plane of the base part.
  • An electrical assembly according to the invention comprises a contactor with two contact bolts and a contact assembly according to the invention, wherein the contact assembly touches the surface shells of the contact bolts.
  • the contact bolt can be contacted at the surface shell.
  • a power consumer can furthermore be connected to the contact bolt at an end face or at another location.
  • this connection is also direct, such that a transition resistance only occurs only one single time. The total resistance is lower as a result.
  • the contacting tab can extend perpendicular or substantially perpendicular to the opening. A compact configuration is possible as a result.
  • the contacting tab can protrude perpendicular to the plane of the base part from the base part. As a result, simplicity of manufacture can be achieved.
  • the contacting tab can have a contact point protruding radially inwards over the rest of the contacting tab, which enables a defined contact.
  • the contact point can be embossed, as a result of which it can be manufactured simply.
  • the contacting tab has at least one stiffening tab which extends radially outwards. Deformation of the contacting tab can be minimised as a result.
  • the stiffening tab can be indirectly connected to the base part. For example, it may be connected to the base part only indirectly via the rest of the contacting tab.
  • stiffening tabs per contacting tab. These can be attached at opposite sides of the contacting tab.
  • the stiffening tab can extend away from the rest of the contacting tab, in order not to impede the contacting of the contact bolt.
  • the contact assembly can have at least three contacting tabs.
  • the contacting tabs can be distributed at equal angles in order to enable a uniform distribution of force. In the case of three contacting tabs, these can span an equilateral triangle.
  • the at least three contacting tabs can form a contact bolt receptacle.
  • contacting tabs can each have at least one notch-shaped receptacle, wherein the notch-shaped receptacles are situated in a plane.
  • a retaining element or spring element which retains or clamps the contacting tabs can be able to be received in the notch-shaped receptacles.
  • the notch-shaped receptacle can be open radially outwards, in order to enable a simple attachment of a retaining element or a spring element.
  • the contact assembly can have an annular overspring for the pressing on of the contacting tab.
  • the overspring can be arranged in the notch-shaped receptacles of the contacting tabs.
  • the contact element can be cast in a plastic carrier.
  • Said plastic carrier can stabilise the contact element.
  • handling can be facilitated, because the plastic carrier can be insulating and, as a result, contact with a live element is prevented.
  • the contact assembly can have two openings for two contact bolts. As a result, it is possible to tap off the voltage between the two contact bolts.
  • the contact assembly can have a plug contact element, which is integrally connected to the base part, for contacting a plug for a voltage tapping.
  • This plug contact element can be bent away from the base part in order to enable a compact configuration.
  • the contact assembly can form a plug receptacle. This makes simple contacting possible.
  • the plug receptacle can in particular be formed by a plastic carrier.
  • the plug receptacle can have a coding so that in each case only one fitting plug can be introduced.
  • the contact assembly can have a coding which, in cooperation with the surrounding housing of the relay, can represent a coding which is independent of the relay.
  • the contact bolts can project above the contact assembly mounted thereon.
  • the contact bolts can protrude out of the contact assembly mounted thereon. This permits a compact configuration.
  • a power consumer can be affixed to the projecting-above or protruding part. For example, a cover surface of the contact bolt can remain free and be used for power contacting.
  • the contact bolts of the contactor can be cylindrical in order to enable simple contacting.
  • Other configurations are also possible, for instance prismatic, conical or other shapes.
  • a shape of which the cross-section remains unaltered as the height changes, for instance a cylinder, is particularly advantageous here, because a contact assembly can be slid on easily.

  • the contact points 33 are embossed.
  • the contacting tabs 31 can be elastically deflected in a deflection direction A which extends parallel to the plane B of the base part 30.

The annular oversprings 4 are attached in the next step (Fig. 9).

  • Fig. 13 is a longitudinal section through the combination of the contact assembly 1 and the contactor 2 in the mounted state. There is a direct contact between the contacting tabs 31 and the contact bolt 21. Likewise, there can occur at a cover surface 22 or in a recess 21 a direct connection to a power consumer, in which only one single transition resistance occurs. Such a current circuit consequently has a lower total resistance than an assembly in which a voltage tapping takes place by introducing an additional element between the contact bolts 21 and a contact element 3 and thus an indirect connection takes place between the contact bolts 21 and the power consumer.

  • a plug receptacle 8 has a coding 40, which in each case only enables the connection of a fitting plug.
