Definitions

  • the invention relates to a connector with a housing made of insulating material, which has at least two mutually parallel rows of contact chambers, in which contact elements can be used, and with a safety slide, which is orthogonal to the direction of insertion of the connector in a gap of the housing to secure the contact elements used can be inserted.
  • Connectors are known for example from DE 3 537 722 A1.
  • an intermediate web is attached in the associated surrounding housing, on which a securing edge is formed, which is formed when the Contact housing protrudes into the outer housing in each contact chamber and thereby grips behind an edge of the contact elements.
  • a secondary securing of the plug contacts within the plug connector and the socket contacts within the plug connector is also required.
  • the plug contacts or socket contacts have been inserted into their respective associated housings (plug strips, relay sockets, etc.) which consist of insulating material, latching elements engage in corresponding openings in these housings and latch there.
  • the secondary fuse is realized in that after the assembly of the connector housing or the socket housing and the aforementioned primary locking of the plug contacts or socket contacts, plastic elements are brought into a position in which they engage behind the contour of the contacts.
  • the plastic elements for the secondary fuse are here as sliding devices, for. B. sliding strips, which are inserted orthogonally to the direction of insertion into the connector plug or into the connector socket and engage with one or more protruding webs edges of the contacts used in the contact chambers of the housing. For safety reasons, these safety slides can only be inserted into the connector housing or into the connector socket when the respective contacts are in the desired position in their contact chambers.
  • the protruding slide can not reach behind the contact with its protruding contour, because it contacts the contact and it is therefore impossible to insert the safety slide.
  • a non-insertable safety slide is noticeable during assembly, so that the connection of the connector plug or connector socket to the corresponding lines must be checked.
  • the safety slide has so far always been implemented in such a way that it only implements a single fuse, namely the secondary fuse of the contacts inserted into the contact chambers.
  • the primary securing of the contact elements takes place in specially designed projections or recesses on the outer walls of the contact chambers, which are completely implemented in the connector.
  • DE 44 07 950 A1 has already described a connector with primary and secondary fuse options, in which one is used as a primary fuse with a first latching tongue of the contact element cooperating primary locking edge is arranged on a fixed contact chamber wall.
  • the opposite second contact chamber wall is designed as a safety slide movable transversely to the plugging direction, which has a segmented and thus interrupted latching edge with the possibility of passage for a second latching tongue on the contact element.
  • the present invention has for its object to provide a connector in which the primary and secondary fuse principle can be implemented in a simple manner, wherein the contact element need only have a single latching tongue.
  • the two broad sides of the locking slide each have a primary locking edge running over their entire wide side, can snap into the locking hooks of the contact elements inserted into the contact chambers, and the two wide sides of the locking slide each have a segmented secondary locking projection edge running below the primary locking edge .
  • the individual segments are spaced so far apart that a contact element can be inserted between two segments. This has the advantage that the contact elements can be easily inserted into the housing.
  • the secondary latching projections can reach behind the contours or edges of the contact elements for their secondary securing.
  • the housing expediently has a spring element on its bottom of the gap facing the insertion direction, into which the safety slide is inserted, in which the safety slide can be latched. This ensures that the safety slide can not easily slide out of the housing when the connector is tilted.
  • a groove is preferably machined into the bottom of the gap of the housing, into which a projection arranged on the underside of the safety slide can be snapped.
  • the spring element in the housing has a first recess and a second recess, the second recess being arranged closer to the interior of the housing.
  • FIG. 1 a possible embodiment of a connector according to the invention is shown in perspective.
  • Reference number 1 denotes the housing of the plug connector and reference number 20 denotes a safety slide 20 which can be inserted orthogonally to the plug direction S into a gap 2 of the housing 1.
  • a contact element 40 which is already inserted into a contact chamber 30 and is designed here as a contact socket can be seen in FIG.
  • a contact chamber 30 is only formed by inserting the safety slide 20 into the gap 2.
  • the housing 1 has slots 11 on its inner wall facing the gap 2, which, spaced apart from one another, each extend parallel in the plug-in direction S. When viewed from above, these slots have a U-shaped cross-sectional shape. Between the individual slots 11 there are webs 12 which separate the slots 11 from one another.
  • each contact chamber 30 is closed at its upper edge by a peripheral edge 13 which has a smaller diameter than the contact element 40.
  • the boundary is identified by reference number 13.
  • the safety slide 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 locking edge 23 preferably extends over the entire width of the locking slide 20.
  • secondary locking projections 24 are provided below these two primary locking edges 23, which can engage behind a contour 42 of the contact element 40 in order to provide a second locking so that the contact element 40 no longer can be pulled out of the contact chamber 30.
  • the individual secondary locking projections 24 are spaced apart from one another to such an extent that a contact element 40 can easily be inserted between two attachable secondary locking projections 24.
  • the space between two secondary locking projections 24 is designated by reference numeral 27.
  • the safety slide 20 has a plurality of longitudinal openings, which are referred to below as auxiliary openings 22 and run parallel to the contact chambers 30.
  • auxiliary openings 22 are arranged in alignment with the intermediate spaces 27 between the secondary locking projections 24 and serve to release the locking tongue 41 from the primary locking edge 23 by passing a suitable pin through the auxiliary opening 22 and pressing the locking tongue 41 from the primary locking edge 41.
  • the safety slide 20 When assembling the connector, the safety slide 20 is first inserted into the housing 1 in a way that the contact element 40 can be inserted into the contact chamber formed by the safety slide 20 and slot 11. When the contact element 40 is inserted correctly, the latching tongue 41 rips behind the primary latching edge 23, so that primary securing is achieved. Then, for secondary securing, the safety slide 20 is moved in accordance with the direction of the arrow P, as a result of which one of the secondary latching projections 24 can engage behind the contour 42 of the contact element 40.
  • FIG. 2 shows various views of the safety slide 20 from FIG. 1.
  • FIG. 2a shows a side view
  • FIG. 2b shows a view from below
  • FIG. 2c shows a view from above
  • FIGS. 2d and 2e each show sectional views through the safety slide 20 from FIG. 2a along the section lines D-D and E-E.
  • Figure 2f shows a plan view of the left end of the safety slide shown in Figure 2a.
  • the reference numerals already known from FIG. 1 are used again for the same parts.
  • the wall sections 21 on the two opposite broad and outer sides of the safety slide 20 can clearly be seen, which represent a wall of the adjacent contact chambers 30 in the assembled state of the housing and the inserted safety slide.
  • FIG. 3 shows the housing 1 of the plug connector already shown in detail from FIG. 1 in a cross-sectional illustration (see FIG. 3a), in a top view (see FIG. 3b), in a view from below (see FIG. 3c) and in sectional views in FIGS. 3d, 3e and 3f along the section lines DD, EE and FF of Figure 3a.
  • the safety slide 20 and the bottom of the gap 2 of the housing 1 have a sliding link guide which is adapted to one another in order to hold the safety slide 20 in place within the housing 1.
  • the openings for the contact chambers of the connector are identified by the reference number 3.
  • a slide groove 10 with two recesses 14, 15 lying next to one another is incorporated on the bottom 4 of the gap 2, as shown in FIG. 3.
  • This link groove 10 with the recesses 14, 15 cooperates with a bow-shaped projection 25 on the underside of the safety slide.
  • the link projection 25 has one on its center protruding link nose 26, which can engage in the two mentioned recesses 14, 15 of the link groove 10.
  • the safety slide 20 is in its pre-latched position. In this position, the contact elements 40 inserted into the respective contact chambers 30 are secured primarily by the primary locking edge 23 already explained, but are not yet secured secondarily. This is only achieved when the safety slide 20 is pushed into the second recess 15. For an operator, these two locking positions are readily recognizable, since a certain amount of force has to be applied when the safety slide 20 is pushed into the gap 2 of the housing 1.
  • the set guide described can in principle be designed as desired, it has proven to be expedient to provide a pre-locking position and a final locking position.
  • the contact elements can already be inserted into the contact chambers 30 and primarily locked, whereby the contact elements are initially held due to each primary locking device.
  • the safety slide 20 is completely pushed into the gap 2 of the housing 1, the final securing of the contact elements 40 is then carried out.
  • the housing 1 has channels 43, between which connecting webs 44 are arranged.
  • These connecting webs 44 are integrally formed on the housing 1 and, starting from the upper contour of the housing 1 shown in FIGS. 3d and 3e, end at the bottom 4 of the gap 2.
  • Two such connecting webs 44 are assigned to each opening 3, the two connecting webs being spaced apart 44 are each arranged on the wall of the respective opening 3 facing the center of the housing.
