  • the invention relates to a connector according to the preamble of claim 1.
  • Connectors are known for example from DE 3 537 722 A1.
  • Contact elements i.e. in the case of connector plugs the plug contacts and in the case of connector sockets the socket contacts, in the associated housing an intermediate web attached to which a safety edge is formed, which when inserting the contact housing in the housing protrudes into each contact chamber and thereby each engages behind an edge of the contact elements.
  • the secondary fuse is realized in that after Equipping the connector housing or the socket housing and the mentioned primary latching of the plug contacts or Socket contacts brought plastic elements into one position in which they reach behind the contour of the contacts.
  • the plastic elements for the secondary fuse are here as sliding devices, e.g. B. sliding strips, realized, the orthogonal to the direction of insertion in the connector plug or inserted into the connector socket and with one or more protruding webs Edges of the inserted in the contact chambers of the housing Get in touch with contacts.
  • the safety slide is on most connectors always realized so far that he only one Fuse, namely the secondary fuse in the contact chambers inserted contacts realized.
  • the primary backup the contact elements take place in particular designed projections or recesses on the outer walls of the contact chambers that are completely in the connector are realized.
  • DE 44 07 950 A1 already includes a connector Primary and secondary backup option described, at which one as a primary fuse with a first locking tongue interacting primary locking edge of the contact element a fixed contact chamber wall is arranged.
  • the opposite second contact chamber wall is considered to be transverse to Plug direction of movable safety slide formed, the a segmented and thus interrupted locking edge Possibility of passage for a second locking tongue on Has contact element.
  • the US-A-5 116 236 a connector with a primary fuse and a secondary fuse.
  • the primary backup is flexible Paired locking hooks formed on the safety slide
  • the secondary fuse is by using the flexible snap hooks in the longitudinal direction of the locking slide, alternating pairs of rigid locking projections educated.
  • the flexible snap hooks can be used with one tool be bent aside to include a contact element in the associated one To be able to use the contact chamber.
  • the contact element is then provisionally in the chamber by an associated flexible snap hook held. If all contact elements are inserted in the housing, the safety slide is moved by half the contact chamber center distance moved so that the rigid locking projections then the contact elements secure in the individual contact chambers.
  • the present invention has for its object a Specify connector in which the primary and secondary security principle can be implemented, wherein the contact element also only a single latching tongue needs to show.
  • the secondary locking projections can behind contours or edges of the contact elements for their secondary fuse. At the Moving the safety slide in the gap in the housing it is therefore possible to use both a primary backup as well a secondary fuse of those used in the contact chambers To ensure contact elements.
  • the housing expediently points in the direction of insertion facing bottom of the gap into which the safety slide is inserted, a spring element in which the safety slide can be snapped into place. This will ensured that the safety slide when tilting the Do not easily slip the connector out of the housing can.
  • a groove incorporated, in which one on the Projection arranged on the underside of the safety slide can be snapped into place.
  • the spring element in the housing has a first Depression and a second depression, the second Depression is arranged closer to the interior of the housing.
  • FIG. 1 shows a possible exemplary embodiment a connector according to the invention in perspective shown.
  • the housing of the connector and with the reference numeral 20 an orthogonal to plug direction S into a gap 2 of housing 1 insertable safety slide 20 designated.
  • 1 is one already inserted into a contact chamber 30
  • Contact element 40 which is designed here as a contact socket is recognizable.
  • a contact chamber 30 only by inserting the safety slide 20 formed in the gap 2.
  • the housing 1 of its inner wall facing the gap 2, slots 11, which are spaced apart from each other parallel in the direction of insertion S extend. Viewed from above, these have Slots have a U-shaped cross-sectional shape. Between individual slots 11 are webs 12, which the Separate slots 11 from each other, arranged.
  • each contact chamber 30 is on their upper edge by a circumferential border 13 the one has a smaller diameter than the contact element 40, completed.
  • the boundary is identified by reference number 13.
  • the safety slide has 20 has an approximately anchor-shaped cross-sectional shape.
  • Primary locking edges 23 are formed on which locking hooks 41 of the contact elements 40 can snap into place.
  • the primary snap edge 23 preferably extends over the entire width of the safety slide 20.
  • are below these two Primary locking edges 23 each have so-called secondary locking projections 24 provided behind a contour 42 of the contact element 40 can grab to provide a second fuse, so that the contact element 40 no longer out of the contact chamber 30 can be pulled out.
  • the individual secondary locking projections 24 are so far apart from each other that between two attachable secondary locking projections 24 without further ado Contact element 40 can be inserted.
  • the space between two secondary locking projections 24 is identified by reference numeral 27 designated.
  • auxiliary openings 22 extending parallel to the contact chambers 30 Longitudinal openings.
  • These auxiliary openings 22 are aligned with the Spaces 27 between the secondary locking projections 24 arranged and serve the locking tongue 41 of the Solve primary locking edge 23 by using a suitable pin the auxiliary opening 22 out and the locking tongue 41 of the Primary locking edge 41 is pressed.
  • the Safety slide 20 in the housing 1 in an idea used so that the contact element 40 in the through Safety slide 20 and slot 11 formed contact chamber can be inserted. With correct insertion of the Contact element 40 behind the locking tongue 41 the Primary locking edge 23 so that a primary fuse is reached becomes. Then the safety slide is used for secondary securing 20 shifted according to the direction of arrow P, whereby one of the secondary detent projections 24 is behind the contour 42 of the contact element 40 can grip.
  • FIG. 2a shows a side view
  • Figure 2b is a bottom view
