Definitions

  • the spring bar described in DE-OS 24 31 220 also has similar disadvantages, in which the contact spring with the connecting part is clamped via an angle between the cover and the bottom part.
  • the connecting part can itself be deformed, specifically in the area where it is welded to the contact spring.
  • each end of each web pointing towards the connection side has a recess, that the projections of the contact elements are each formed on the press-in pin and that each projection engages in the recess of the associated web.
  • the invention is always implemented when the contact elements are arranged or anchored in the housing or in the cover in such a way that they absorb the forces acting on the housing and can convert them into press-in forces so that the active parts of the contact elements, namely the spring tongues are fully relieved.
  • the invention therefore no longer requires a tool with pins in order to be able to connect the socket to a plate. Rather, with the invention it is possible to establish the connection between the socket and the plate without complicated tools.
  • the forces acting on the housing during the establishment of the connection are absorbed exclusively by the pins, which regularly consist of a harder and stronger material. Since the spring tongues do not come into contact with any tools, they cannot be damaged.
  • An expedient measure of the invention provides that the recesses are open towards the lid.
  • the Measures must also be taken such that the recesses are open towards both the cover and the longitudinal central axis of the contact chamber.
  • This measure of the invention ensures that even at high pressure that can act on the housing, there can be no displacement or displacement of the plastic material in the region of the recesses, since this is due to the boundary walls of the recesses and the addition to the V-shaped recess for the leading ground contact pulled area of the pin is prevented. The material simply has no way of leaving the recess.
  • each recess which is in pressure connection with one of the projections, runs at right angles to the longitudinal center axis of the contact chamber, then there is an optimal transmission of forces from the contact chambers to the pins.
  • a further advantageous measure of the invention provides that each recess in the direction of the cover in a groove, which is formed in the associated inner wall of the contact chamber and runs parallel to it, runs out into the insertion opening of this contact chamber for the contact element. It is expedient here if the cross section of the groove is stepped with respect to the counter-guide parts.
  • each projection has a support section running transversely to the plug-in direction and a guide section running parallel to the plug-in direction, the transition zone between these sections being rounded off, it is ensured above all that the spring body cannot be tilted during the assembly of the contact spring strip. It is useful if all the transition areas in the projections are rounded because the contact elements are made of a considerably harder material than the housing, so that the slightest inaccuracies when inserting the contact elements into the contact chamber can damage the housing.
  • leading knife contacts are often used to discharge unwanted charges. So that these leading knives do not collide with the pin and the two parts are damaged as a result, the end of the pin facing the knife contact pins can have a recess for leading knife contact pins tapering towards the other end of the pin. In this way, manufacturing-related irregularities can also be compensated for in the knife contact pins.
  • a measure of the invention provides that the cover has locking bodies with lugs which engage in recesses in the housing.
  • the advantages achieved by the invention are, in particular, that even when the interior of the housing is changed, the production of the contact spring strips can be carried out just as easily as the production of the conventional contact spring strips, without foregoing the advantages of the conventional contact spring strips.
  • the most important advantage, however, is the fact that no special tool is required to make the connection between the contact spring strip and the plate.
  • FIGS. 3 and 4 show part of a contact spring strip with a housing 8 and with openings 12, 14 of a socket with a cover 18 with through openings 20 arranged in contact chambers 10 with openings 12, 14 therethrough.
  • the contact elements 22 (cf. in particular FIGS. 3 and 4) consist of V-shaped springs with two legs 30, 31 with guide sections 34, 36, 38, which with counter-guide sections 40 formed in the inner wall of the contact chamber 10 and extending axially, 42 (cf. in particular FIG. 5) work together.
  • the contact elements 22 have spring tongues 50, 52, which can cooperate with knife contact pins (not shown in more detail) of a male connector, and the webs 62, 64, which are arranged between two counter-guide sections 40, 42 and protrude toward the central longitudinal axis 60 of the contact chamber 10, the latter for the cover 18 oriented end sections taper, are kept apart.
  • the contact element 22 also has a press-in pin 68 which emerges from the contact chamber 10 protrudes and crosses the lid 18.
  • the axial region of the web 62 has a recess 70.
  • the contact element 22 has two pin projections 74, 76 which run transversely to the longitudinal center axis and are supported in a fixed manner in the recesses 70, 71 of the web 62.
  • the part of the press-in pin 68 which cooperates with the cover 18 has a barb-like extension 80 which tapers towards the free end of the press-in pin 68 and is slightly wider than the width of the cover opening 82.
  • the end of the groove 84 formed in the insertion opening 86 has an extension 90, which serves for better insertion of the pin projections 74, 76 into the contact chamber 10.
  • the cross section of the groove 84 is stepped with respect to the counter-guide sections 40, 42. It can be seen (see in particular FIGS. 6 and 7) that two opposing webs 62, 64, each with a recess 70, 71, are formed in the contact chamber 10. Both webs 62, 64 taper towards the cover 18, the recesses 70, 71 being formed within the taper, the ends of which are rounded.
  • the contact element 22 consisting of two stamped parts has two pin projections 74, 76, the width of the contact element 22 in the area of the pin projections 74, 76 corresponding approximately to the width of the contact chamber 10 in the area of the recesses 70, 71. It is thereby achieved that the sides of the pin projections 74, 76 running parallel to the longitudinal central axis of the contact element 22 can slide on the walls 100, 102 of the groove 84 or of the recesses 70, 71. It can be seen (cf. in particular FIG. 3) that the pin projections 74, 76 each have a support section running transversely to the plug-in direction and a guide section running parallel to the plug-in direction, the transition zone 104, 106 between these sections being rounded off. Furthermore, the press-in pin has a zone 80 which, due to oversize, sticks in the cover 18 and thus absorbs part of the axial forces during the press-in process and thus relieves the support in the area of the pin projections 74, 76.
  • the press-in pins 68 also have press-in zones 112, the width of which corresponds approximately to the width of the through openings 20 in the cover 18.
  • the cover 18 has latching bodies 120 directed towards the socket with lugs which can be detachably connected to recesses in the socket.
