Definitions

  • the invention relates to an arrangement for contacting flat film conductors of a film with at least one contact with a first region for connection to the flat film conductor and a second region for further contacting and with a housing for receiving the contact, wherein the housing has a first part with a front portion with at least one contact chamber for receiving the second region of the contact and a rear portion for receiving the first region of the contact and the flat foil conductor and having a second part which serves as a cover of the rear portion.
  • This contact has two areas, one of which has a base plate with at least one toothed crown for contacting the flat film conductor.
  • a base plate with at least one toothed crown for contacting the flat film conductor.
  • two toothed crowns are provided and on each side of the base plate a Crimpflanke is connected. The teeth and Crimpflanken be folded for contacting the film conductor with a tool.
  • a contact for flat film conductor is also known, having serrated crowns.
  • the serrated crowns serve both for contacting and for fixing the foil conductor to the contact.
  • the teeth of the toothed crown are put to it.
  • US 5,643,005 discloses an arrangement for contacting a plurality of individual insulated conductors via insulation displacement contacts. Each conductor is contacted by two successively arranged insulation displacement contacts, which belong to two contact parts, which have a contact area at the other end. The contact areas are arranged in a first Gaffeuseteil in two rows one above the other.
  • This housing part with the contacts can be introduced into a surrounding housing. To introduce the conductor into the insulation displacement contacts, the conductors are first inserted into a cover part of the housing and then pressed with this on the lower part of the housing and in the insulation displacement contacts. In this case, the cover part has two parallel grooves, in each of which a number of insulation displacement contacts come.
  • the contacts are first introduced into the housing, wherein the second part of the housing is in the insertion position. Thereafter, the film with the flat film conductor is inserted into the housing until it stops. Then the second part is pressed into the end position, wherein the teeth of the toothed crown penetrate the foil conductor and enter into the recesses provided for this purpose. This ensures that the flat film conductor is contacted by the tines.
  • the prongs meet when entering the recesses on a slope and are bent or forced out of this outwards or inwards.
  • the contact point By the bending of the teeth is the contact point additionally fixed and thus the contact additionally secured.
  • the second part is connected in the insertion position with the housing and therefore is captive.
  • the film is held securely in the housing. This is ensured by ripping and / or connecting the housing parts to one another by ultrasonically welding or hot-caulking.
  • the arrangement for contacting flat film conductors consists of a housing 1 and at least one electrical contact 2.
  • the contact 2 is used for contacting the flat film conductor of a film 3 on the one hand and for contacting a complementary contact on the other.
  • the electrical contact 2 in the given exemplary embodiment is a socket contact. It would also be possible to provide a pin contact or otherwise equipped contact instead of a socket contact.
  • the contact 2 has a first region 20 for connection to a Falchfolienleiter and a second region 21 for contacting a complementary contact pin.
  • the first region 20 of the contact 2 has a base plate 22 on, in the longitudinal direction one behind the other two serrated crowns 23 and 23 'has.
  • the serrated crowns each consist of four prongs 24, which are exposed from the base plate 22 and bent upwards. At the film side end of the base plate is a bent from the base plate web 25. This web 25 serves as a stop when the contact 2 is introduced into the housing 1.
  • the second region 21 of the electrical contact 2 is designed as a socket contact with four contact springs 26 arranged on the four sides.
  • the contact spring are surrounded by an outer over-spring 27, which has a detent spring tongue 28.
  • the detent spring tongue 28 is used for latching and first securing the contact in the housing 1.
  • the outer over-spring 27 has in addition to the detent spring tongue 28 also has a polarizing rib 29, which ensures that the contact 2 is properly polarized introduced into the housing 1.
  • the housing 1 consists of a first part 10 and a second part 11.
  • the first part 10 has a front portion 12 with at least one contact chamber 13.
  • the contact chamber 13 serves to receive a contact 2.
  • the contact chambers 13 have to the front end 14 of the housing 1 has a passage opening 15 for an electrical contact pin.
  • the second area 21 of the contact 2 is received in the main.
  • the first region 20 of the electrical contact 2 is received in the rear portion 16 of the first part 10 of the housing 1.
  • the rear portion 16 is in Essentially of a base plate 17 on which the first portions 20 of the contacts 2 rest.
  • This base plate 17 also has stops 18 for interacting with the webs 25 of the contacts.
  • the rear part has two side walls 19, which cooperate with the second part 11 of the housing 1.
  • the front portion 12 of the first part 10 has above each chamber a window 30 in which the detent spring tongue 28 of an electrical contact is locked. As a result, a first securing of the contacts 2 in the housing 1 is ensured.
  • FIG. 3 shows a view of the second part 11 of the housing 1 from the side facing the film.
  • This cover is applied to the first part 10 of the housing 1 parallel to the base plate 17.
  • the locking lugs 30 engage in the corresponding recesses 31 of the side walls 19 of the rear portion 16 of the housing 1.
  • the second part 11 is in a Einbring- or Vorrastwolf in the contacts and the Foil can be introduced into the housing.
  • pressure on the second part 11 this is brought from this pre-locking position into an end position, wherein the latching lugs 30 engage in the latching openings 32.
  • the contacts are introduced into the housing with the second part in the pre-locked position and then the film is inserted.
  • the housing has stops 33 against which the film should start. These formed as wall parts stops also serve to guide the second part 11 during insertion of this part.
  • the second part 11 also has window openings 34, are determined by the can, if the film was introduced to the stops 33 in the housing 1. If this is the case, then the second part 11 can be brought into the end position.
  • the second part 11, has recesses 35 which serve to receive the serrations 24 of the serrated crowns 23.
  • the recesses 35 are provided in such a way that they have a bevel, which causes the prongs to be bent outwards during insertion. This ensures that the contact point is held securely.
  • the second part 11 also has ribs 36 which serve to hold down and fix the film.
  • these ribs 36 may be formed of an elastically deformable material such that they exert pressure on the film to ensure contact. Ensuring the contacting is also achieved by further trapezoidal ribs 37 are provided, which serve to weld the second part 11 with the rear portion 16 of the first part 10 with ultrasound.
  • posts 38 are provided on the second part 11, which cooperate with openings 39.
  • the posts 38 engage in the end position in the openings 39 and latch by means of complementary locking means 40 in this.
  • the second part 11 also serves as a second contact assurance for the contact 2 in the housing 1 when it is in the end position.
  • a particularly advantageous introduction of the second part in the first part is given when the housing is placed in a surrounding housing. It may then be provided that the surrounding housing with gate grooves and the second part to be provided with corresponding sliding blocks, such that upon insertion of the housing in the surrounding housing, the second part is forcibly guided to its end position.
