Definitions

  • the invention relates to a contact spring which is intended to be received in a plastic strip housing which has continuous chambers for the springs between a front and a rear side and in which the contact springs consisting of a contact spring part and a connecting part have an end section of the connecting part protrude on the back of the strip housing, and in which the contact spring leg having contact spring part and the post-like connecting part are separately manufactured, interconnected parts, of which at least one with at least one appropriately designed projection in a recess parallel to the course of the contact springs from two together lockable housing halves existing strip housing is lockable.
  • Such a contact spring is known from DE-AS 24 31 220.
  • the post-like connecting part is provided with a 90 ° bend at its end facing the contact spring part. This bend is clamped in a recess between the upper and lower parts of the contact spring strip.
  • torsional stresses which occur especially when the connection part is used as a wrap handle, are safely absorbed by the housing and cannot have an effect on the contact spring part of the contact spring.
  • connection parts protruding from the strip housing are used as contact blades, which are intended to be pressed into the grid bores of a printed circuit board, then such a 90 ° bend of the connecting part, which is fixed in the housing, is less suitable for absorbing the forces which occur during the pressing in.
  • the object of the invention is therefore to design a contact spring of the type mentioned in such a way that, in particular, the forces occurring when the sections of the connecting parts projecting from the housing are pressed into grid bores of a printed circuit board are reliably transmitted to the strip housing without the contact spring part of the contact spring being impaired becomes.
  • the contact spring legs are attached to mutually opposite edges of a flat base plate provided transversely to the course of the contact spring and the base plate is provided on both sides of the contact spring legs with widenings which form the lugs of the contact spring which can be supported in the strip housing and that the post-like connecting part is supported on the side of the base plate facing away from the contact spring legs and is connected to the latter.
  • the connecting part is supported when pressing its protruding portion from the strip housing into the grid hole of a circuit board on the base plate and this with the widenings on the upper part of the strip housing, so that the contact spring legs can in no way be damaged by the forces occurring during the pressing .
  • the contact spring legs have a section cut free with respect to the widenings of the base plate.
  • the widenings on the base plate can advantageously run completely flat, without the contact spring cross section being enlarged by the curvature of the contact spring legs that starts on the base plate.
  • the post-like connecting part is provided with a section widened in cross section.
  • This design of the contact spring enables reliable contact between the connection part and the metallization of the raster bores of a printed circuit board, and due to the special interception of the press-in pressure, the increased press-in pressure required to press in the connection parts designed in this way also safely onto the strip housing without endangering the contact spring part of the contact spring is transmitted.
  • the widenings of the base plate are supported on a supporting wall of the upper part of the strip housing and that this supporting wall is formed by the end of a rib projecting into a chamber facing the lower part of the strip housing, which supports end approaches the contact spring leg is provided.
  • FIG. 1 and 2 show the contact spring in side and front views and FIG. 3 shows a section of a strip housing shown in section with contact springs arranged in chambers of the strip housing.
  • the contact spring 1 is composed of a contact spring part 2 and a connecting part 3.
  • the contact spring part 2 consists of a flat base plate 4, which is arranged transversely to the course of the contact spring 1. At opposite edges of the base plate 4 there are integral contact spring legs 5 which are connected to the base plate 4 and which have contacts 6 at their free ends, between which a contact pin or a contact knife can be inserted (not shown).
  • the base plate 4 is provided with widenings 7 which fit into recesses 10 when the contact spring 1 is inserted into the chambers 8 of the plastic strip housing 9, which extend in the direction of a contact spring inserted into a chamber 8 through support walls 11 from above - or lower part 12, 13 of the strip housing 9 are limited.
  • the support wall 11 on the upper part 12 of the strip housing 9 is advantageously formed by the lower part 13 of the strip housing 9 facing the end of a housing rib 14 protruding into the interior of a chamber 8, which is provided for pre-opening or centering the contacts 6 of the contact spring legs 5.
  • Grooves 16 are formed between the rib 14 and the walls 15 of a chamber 8 running at right angles thereto, which receive end approaches 17 of the contact spring legs 5.
  • connection part 3 On the side of the base plate 4 facing away from the contact spring part 2, the post-like connection part 3 is butt welded to the base plate 4.
  • the connecting part 3 protrudes from the center of the base plate 4 in the axial direction of the contact spring 1.
  • the connector 3 is through Splitting and pushing apart the legs obtained by the splitting enlarged in cross section.
  • the two legs in section 18 of the connection part 3 can be pressed elastically against each other when the connection part 3 is pressed into the grid bore of a printed circuit board and in this way ensure good contact between the connection part 3 and the metallized wall of a grid bore of the circuit board.
  • the widenings 7 of the base plate 4 are supported on the support walls 11 of the housing ribs 14 of the upper housing part 12 and thereby ensure a reliable transmission of the press-in force from the upper part 12 to the connecting part 3 of a contact spring.
