Definitions

  • the present invention relates to a contact element for establishing an electrical contact between two contact pieces according to the preamble of claim 1.
  • contact lamellas which can also be referred to as contact lamellas, have become known from the prior art.
  • the EP 0 716 474 a contact element which comprises a one-piece contact strip which extends along a longitudinal direction and with which two opposite contact surfaces can be electrically contacted.
  • the length of the contact strip can be easily deformed so that it is easy to install.
  • the contact lamella has according to the EP 0 716 474 some disadvantages.
  • the scalability with regard to the electrical currents to be transmitted is very limited.
  • an increase in the current is also accompanied by an increase in the cross section of the contact element.
  • Such a scaling is not easily possible because otherwise advantageous properties are lost.
  • the contact element becomes stiffer when it is enlarged.
  • the mechanical insertion force can only be influenced slightly if the lamella is used in a socket or plug connection.
  • the area of use or the spring deflection area is also restricted with regard to the geometric dimensions between the two contact surfaces.

  • the invention is based on an object of specifying a contact element which overcomes the disadvantages of the prior art.
  • the contact element should be more easily configurable for different applications.
  • a contact element for establishing an electrical contact between two contact pieces comprises a carrier strip extending in the longitudinal direction and a plurality of contact parts which are connected to the carrier strip.

  • the contact parts which are responsible for the actual electrical contact switching, a defined electrical contact can be achieved between the two contact pieces. Due to the carrier tape, which is variable in its length, it is possible, in particular when installing the contact element, to stretch or compress it without affecting the contact parts. In this way, the contact parts can be dimensioned with regard to the electrical contact function and the longitudinal stretchability of the carrier tape can take place independently of the dimensioning of the contact part. This means that the two functions "electrical contact” and "longitudinal stretchability" can be dimensioned independently of one another.
  • That the carrier tape is designed such that the length of the carrier tape changes in the longitudinal direction when a force is applied to the carrier tape” is understood to mean that the carrier tape as such is designed such that its length changes when the force is applied.

  • the carrier tape extends cylindrically around a central axis, with then the line and the pivot line also extend cylindrically around the central axis.
  • the expression that the line and the pivot line are parallel is to be understood to the effect that the cylindrical circumferential line and the cylindrical circumferential pivot line lie in parallel planes which are transverse to the central axis.
