Definitions

  • the invention relates to an electrical connector with a housing having a plurality of contact chambers arranged in at least one row with contacts in the contact chambers and with a hinged flap having projections which extend into the contact chambers in a locking position of the flap to secure the contacts therein which is also suited for flat foil conductors.
  • the electrical connector comprises a main housing with a plurality of contact chambers arranged in one row, for receiving contacts therein and a subhousing having projections that extend into the contact chambers in a locking position of the subhousing to secure the contacts therein.
  • the subhousing has a shaft that is slidingly introduced into a bearing track on the housing in a direction perpendicular to a mating direction of the connector. When slid to the end of the track, the subhousing is in its locking position.
  • the connector comprises a housing with chambers for terminals and a pivotable flap that is used to press the flat foil conductor against the terminals.
  • DE 29805026 Ul discloses a electrical connector with a housing with a plurality of contact chambers arranged in two rows, for receiving contacts therein and a flap on either side of the housing, the flap having projections that extend into the contact chambers in a locking position of the flap to secure the contacts therein.
  • the flaps are moulded as a separate part and mounted on the housing and are moved transversally to a mating direction of the connector to be closed.
  • GB 1525046 discloses an electrical connector with three contact chambers arranged in a row in a housing with contacts therein and a hinged flap with projections. The projections extend into the contact chambers in a locking position of the flap to secure the contacts therein where the hinged flap is connected to the housing via a film hinge.
  • US 4,082,402 discloses a contact and an electrical connector for flat foil conductors.
  • the electrical connector includes a housing with nine electric contacts arranged in a row, the contacts being suitable for connection to the conductors of a foil and for engaging a mating contact.
  • the housing includes a flap which is hinged to the housing via a film hinge and which can be connected in a locked manner to the housing in a locking position. The flap serves to protect the connections between the contacts and the flat foil conductors. Additional securing of the contacts in the contact chambers is not effected by the hinged flap. Further strain relief on the connector is also not provided.
  • a further object of the invention is to provide a connector for flat foil conductors that includes additional strain relief for the flat foil. The object is achieved by a connector having the features of claim 1. The sub-claims provide advantageous developments.
  • a connector according to the invention includes a strain relief for the flat cable.
  • this strain relief is formed integrally with the housing. This prevents loss of the small pins typically used to provide strain relief.
  • a further particular advantage is that, when producing the housing for the connector, the flap and the housing can be produced as two separate parts using very simple tools, these two parts being adapted for assembly upon opening of the tools and then being connected to one another by a hinge.
  • a further particular advantage is that the flap on the housing locks in a pre-locking position and therefore prevents unintentional removal of the flap from the housing.
  • a further particular advantage is that, with the connector according to the invention, the foil is initially terminated at the contacts and the contacts then introduced into the housing with the foil.
  • the strain relief of the foil is initially effected by the corresponding arrangements and the flap can then be brought into its end position to check whether the contacts are located in the correct position.
  • the contacts also have a so-called first contact securing means, for example, the contacts have a spring tongue which locks behind a corresponding housing shoulder when the contacts are introduced fully into the housing chambers.
  • a secondary contact securing means of a connector according to the invention will initially be described with reference to Figures 1 to 7.
  • Various strain relief arrangements will then be described with reference to Figures 8 to 12.
  • Figures 1 to 7 show various perspective views and a cross-section of a connector 1 according to the invention. Only a housing 2 and a flap 3 is shown in some figures ( Figures 1 to 3 and 7), whereas Figures 4, 5 and 6 also show a foil 4 introduced therein.
  • the housing 2 includes a face 5 and a cable end 6.
  • the housing 2 includes eight contact chambers 7 arranged in a row.
  • the contact chambers 7 extend from the face 5 to the cable end 6 of the housing 2.
  • Each contact chamber 7 serves to receive an electric contact.
  • the electric contact is so designed that it can be assembled with a mating contact and includes a region for engaging a flat foil conductor of the foil 4.
  • Each contact also includes, for example, a catch spring tongue with which it locks behind a shoulder 8 of the contact chamber 7 when the contact is inserted into the contact chamber 7.
  • Each contact chamber 7 also includes an opening 9 through a lateral wall 10 of the housing 2.
  • the housing 2 includes, on opposing sides, a catch arm 11 for interlocking with a mating connector.
  • the housing 2 also includes a strain relief 12 on each side at the cable end 6.
  • the housing 2 includes a bearing track 13 along the lateral wall 10. This is bounded by one of the strain relief arrangements 12 on one side and includes an opening 14 on the other side.
  • a flap 3 is provided next to the housing 2.
  • the flap 3 consists of a plate, a shaft 15 being provided at one end of the plate and a row of projections 16 at the other end of the plate.
  • the number of projections 16 corresponds to the number of chambers 7.
  • the flap 3 and the housing 2 are produced independently of one another from a thermoplastic material. During the opening of the tools for the injection moulding of the two parts, it is proposed that the flap 3, with shaft 15, be inserted automatically into the bearing track 13 through opening 14.
  • Figure 1 shows the state of flap 3 and housing 2 prior to insertion.
  • Figures 2 and 5 show the flap 3 inserted into the housing.
  • Three longitudinal recesses 17 extend parallel to the shaft 15 are arranged in the flap 3 close to the shaft 15.
  • Three projections 18 are accordingly located on the lateral wall 10 above the shaft bearing 13. When the flap 3 is located in its end position on the housing 2, the projections 18 are arranged above the openings 17. If the flap 3 is accordingly rotated round the shaft 15, the projections 18 engage in the openings 17 and ensure guidance of the flap 3 in the direction perpendicular to the plug-in direction S.
  • a lug 19 is provided on one side of the flap 3.
  • the lug 19 interacts with the wall 20 and therefore the opening 14.
  • the lug 19 is guided past the wall 20 in an interlocking manner. This ensures that the flap 3 is located in a pre-locking position from which it cannot be removed accidentally. Accidental removal of the flap 3 from the housing 2 is thus prevented.
  • the projections 16 of the flap 3 run against the openings 9 in the lateral wall 10. Owing to further pressure on the flap 3 in the direction of the housing 2, the projections 16 penetrate into the recesses 9 in the individual chambers 7 and therefore into the chambers 7. The contacts are therefore secured in the chambers 7.
  • the strain relief arrangement 12 includes a slot 30 into which a section of the foil 4 can be inserted.
  • the section of the foil 4 includes an opening 31.
  • a pin 34 is arranged in one of the two hollow cylinders 33.
  • the pin 34 is connected to the internal wall of the hollow cylinder 33 via a set breaking point 35.
  • the strain relief 12 also includes a slot 31 and the foil 4 is also provided with an opening 31.
  • the diameter of the post 37 is somewhat smaller than the internal width of the hollow cylinder 33.
  • the post 37 is also connected to the housing 2 on one side only and has a slot 39 on the other side so that the post 37 is slightly resilient. Owing to this arrangement, it is possible to introduce the foil 4 with opening 31 through the slot 31 and over the post 37 so that the foil 4 is secured against extracting forces.
