Definitions

  • ABSTRACT This device relates to a holding arrangement for reed contacts [52] us. Cl. ..200/l68 R, 200/166 BH i a plastic body provided with oblong hole-shaped recesses [51] Int- Clinto the upper half of which each time two oppositely directed Field of Search loo/168 R, 166 166 flexible remaining portions project, of which respectively one 317/101 CC, 101 CP; 336/65; 174/167 is cutoff.
  • the present invention relates to a holding arrangement for reed contacts used in switches, pushbutton keys and the like.
  • hermetically sealed contacts instead of the open contacts.
  • different kinds of holding arrangements for the reed contacts have become known. Except for reed relays in which the contact tubes are arranged within the coils, the most simple holding arrangement is characterized by the fact that the two connecting terminals are soldered to the soldering terminals of a printed circuit, thus being simultaneously utilized as a mechanical mounting means, as far as lying contacts are concerned.
  • the terminals are soldered to two different parallel plates or else, in the absence of a second plate, the free terminal is connected to the plate or board with the aid of a connector strip, with this strip simultaneously being designed to serve as a holding arrangement for the reed contact.
  • FIG. 1 shows the plastic body as the starting material
  • FIGS. 2 and 3 show this body with each time two reed contacts inserted in different positions.
  • FIG. 1 illustrates the hole pattern of the plastics body 1 which may have outer contours adapted to the respective purpose, hence may either have the shape of a die-castor molded block of a punched strip, or may form part of another component, such as a pushbutton-key body.
  • the depth of the body corresponds to almost one-third to one-half of the length of the reed contact (2) to be held in position.
  • the cross section of the recesses 3 corresponds in the lower half 4 to that of an oblong hole, whereas two oppositely directed flexible remaining portions 6 project into the upper half 5, with the roots of these remaining portions appropriately lying somewhat outside the imaginary circular arc of the hole, so that these remaining portions, if so required can be easily cut off.
  • the height of the recess 3 is adapted to the diameter of the reed contact.
  • FIGS. 2 and 3 show two different arrangements of each time two reed contacts 2 within the plastics body I.
  • the shape of the recess 3 resembling that of an oblong hole, permits the in sertion of the contact 2 randomly either in the left-hand or in the right-hand half.
  • the respective disturbing remaining portion 6 is cut off at 7, whereas the other remaining portion 6, when inserting the reed contact 2 will give way upwardly, and is clamped between the ceiling of the recess and the reed tube. In this way the reed contact 2 is given a very firm seating without impairing its easy interchangbeability.
  • both reed contacts 2 may also be arranged either on the right-hand or on the left-hand side of the recesses.
  • An arrangement for holding reed contacts comprising a plastic body
  • said recesses including distinctly different upper and lower portions
  • each recess resembling the shape of an oblong hole
  • each recess including two elongated portions projecting from opposite sides of the respective recess directly into the recess to provide uneven upper and lower recess portions.
  • a reed contact is fitted tightly into the space between the remaining elongated portion and the side of the corresponding recess.
  • a reed contact is fitted tightly into the space between each remaining elongated portion and the side of the corresponding recess.
  • a reed contact is fitted tightly into the space between each remaining elongated portion and the side of the corresponding recess.
