Definitions

  • the invention relates to a contact spring formed from a sheet metal strip, in which at one end of the strip a strip section is bent back in a U-shape opposite to the course of the strip and the strip has a cutout in the region of the bend for inserting a contact pin or contact knife.
  • Such a contact spring is from US-PS Re. 29 513 known. It is clear that in this known contact spring to achieve a sufficient spring travel, the bent-back section must be dimensioned relatively long and that therefore a contact knife intended for contact with such a contact spring must also have a relatively large length in order to reach the distance from the free end of the contact spring to be able to penetrate the bent-back section of the contact surface formed.
  • one of the two contact surfaces, namely the contact surface, which is located on the side of the unbent part of the strip is relatively rigid, so that the clamping effect, that is to say the contact force, has to be largely generated by the bent portion.
  • this object is achieved in that a first of two mutually opposing contact surfaces of the contact spring is provided by a region of the U-shaped bent-back strip section directly adjoining the U-shaped bend and the second contact surface is provided directly adjacent to one of the U-shaped bends free end of a tongue cut out of the sheet metal strip in the direction of the strip is formed.
  • the first contact surface is part of an arm directed transversely to the direction of the strip and that either the strip is divided in the direction of the contact surfaces into two mutually parallel webs that the arm only at one end with the U -shaped bent back a web is and that the tongue is formed by the other web, or that the strip towards the contact surfaces consists of three mutually parallel webs and that the arm as a crosspiece connects the two outer longer webs, which are bent back in a U-shape, and the tongue through the shorter middle web is formed.
  • the contact spring is made from a spring sheet metal strip 1, which is formed at one end by a stamping process and any subsequent bending into a pin-shaped or knife-shaped connecting element 2.
  • the sheet metal strip 1 is divided at its other end into two webs 3, 4 arranged next to one another in the direction of the strip 1.
  • the longer of the two webs 3 has at its free end 5 an arm 6 provided transversely to the direction of the strip 1.
  • This, at its free end 7 widened arm 6 is dimensioned so that it with its widening 8 in the unbent state of the Strip 1 is separated from the web 4 by an air gap 9 in the extension of the shorter web 4.
  • the shorter web 4 is provided with a curvature at its free end and forms a contact surface 10 of the contact spring in the region of this curvature.
  • the arm 6 With its widening 8 is juxtaposed with the contact surface 10 of the shorter web 4.
  • the widening 8 of the arm 6 forms a further contact surface 11 with the surface that lies opposite the contact surface 10 of the shorter web 4.
  • both contact surfaces 10, 11 of the bend 18 of the longer web 3 are provided immediately adjacent to one end of the contact spring, so that a contact pin or a contact knife does not require a great length to pass between the contact surfaces 10, 11 reach.
  • both contact surfaces 10, 11 are components of resilient webs, so that the contact surfaces 10, 11 can lay with an optimal spring action against a contact pin inserted between these surfaces or a contact knife inserted between these surfaces.
  • the strip 1 is divided into three mutually parallel webs 12, 13, 14 at the end of the strip which faces away from the connecting element 2.
  • the two outer ones Crosspieces 12, 14 are connected to one another at their free end by the arm 6 and the arm 6 has the widening 8 in its center, which is thereby an extension of the shorter arm 13 which is separated from the widening 8 in the direction of travel by an air gap 9 of the strip 1 is separated when the two outer webs 12, 14 are in the unbent state.
  • the widening 8 of the arm 6 is compared to the free end 15 of the shorter web 13 by a U-shaped back bend 18 of the outer webs 12, 14.
  • the opposing surfaces of the widening 8 of the arm 6 and the free end 15 of the web 13 are designed as contact surfaces 10, 11, between which a contact pin or a contact knife can be inserted, which or is passed through a window 16, the is limited by the curved areas 17 of the longer webs 12, 14.
  • the individual sheet metal strips 1 can be worked out as rungs of a ladder-shaped sheet metal strip from the sheet metal strip, the contact surfaces 10, 11 being located on the same side of the sheet metal strip due to the special design of the contact spring and also on each strip concentrate a narrow area 19, which favors the coating of the areas of the strips 1, which are provided for forming the contact surfaces 10, 11, with precious metal.
