Definitions

  • the electrical contacts can constitute lugs, sockets, pins, clips, extenders, the contact itself being pluggable, built-in, spring-loaded, screw, etc.
  • These contacts or contact parts can be mounted on the wires by screws, clamps, crimping, etc. In the case of crimping, this can be carried out bare wire, by insulation displacement contact, by insulation perforation ...
  • the present invention relates to any electrical contact comprising a barrel to be crimped by perforating insulation. It is applicable both to single-strand wires, as well as to the hair or cables called ORFAL ( R ), formed from spiral blades around a cotton strand and particularly used in telephony.
  • ORFAL R
  • the advantage of crimping through insulation perforation is on the one hand that it avoids long and costly labor and ensures increased productivity during assembly, and on the other hand that it avoids damaging the conductor at during the stripping operation, which is particularly important for very thin conductors.
  • the object of the invention is to remedy these drawbacks and to make contacts the barrel of which allows crimping of wires of various types with great reliability both as regards the quality of the contacts and the retention of the wires.
  • the barrel according to the invention is of the type defined in claim 1.
  • the barrel is produced by cutting and forming a brass sheet of 0.25 mm of brass in the general shape of a gutter.
  • the bottom 1 of the gutter has two tongues 2 and 3 cut and raised approximately perpendicular to the axis of the gutter.
  • at least one of the tabs can be slightly inclined towards the contact part 4 of the clip.
  • the wings 8 and 9 of the gutter 1 are crenellated: the hollows 10 of the slots are in front of or to the right of the tongues, while the teeth or projections 11 are located on either side of the tongues 2, 3.
  • the wings 8 and 9 of the gutter 1 are crenellated: the hollows 10 of the slots are in front of or to the right of the tongues, while the teeth or projections 11 are located on either side of the tongues 2, 3.
  • the edges of the teeth 11 are thinned or tapered into knife blades.
  • the teeth 11 of the slots penetrate the insulator and ensure good contacts with the conductors 12 held in place by the Vs of the tongues; the insulator 13 flows in the sticks of the wings 8 and 9 but also in the punctures 14, 15 left open by the cutting of the tongues 2 and 3.
  • the driver takes the winding course represented ; the edges of the V penetrate to the conductors 12, multiply the contacts; the points 6, 7 of the V also penetrate into the insulation and contribute to the contacts.
  • the tensile strength is increased by a slight inclination of one of the tabs.
  • the contact barrel according to the invention applies equally to lugs, pins, various sockets, as to a clip as shown and in general to any electrical crimp contact.
  • each wing 8 9 has three teeth 11 on either side of these tongues. But it goes without saying that we can adopt a different number of tabs each framed between two teeth of slots.

Claims (5)

1. Elektrischer Kontakt mit einer Preßbuchse, die durch Stanzen und Verformen von Metallband eine insgesamt rinenartige Form erhält und deren Flügel bei dem Quetschvorgang auf den Draht umgebördelt werden, wobei der Boden (1) der Rinne mindestens eine Zunge (2, 3) aufweist, die im wesentlichen senkrecht zu der Achse der Rinne gestanzt und umgebogen ist, während die Flügel (8, 9) zinnenförmig (10, 11) geschnitten sind, wobei die Ausschnitte (10) den Zungen (2, 3) gegenüberliegen und die Zähne (11) beiderseits der Zungen (2, 3) stenen,
dadurch gekennzeichnet, daß
- die Zungen (2, 3) eine Kante in Form eines zur Richtung der Öffnung der Rinne hin offenen V haben, welche Kante während des Quetschvorgangs bis zu den Leitern (12) in den Isoliermantel des Drahtes eindringen soll, und daß
- die Zähne (11) während des Quetschvorgangs bis zu den Leitern (12) in den Isoliermantel des Drahtes eindringen,
- so daß der elektrische Kontakt gleichzeitig durch die Zungen (2, 3) und die Zähne (11) hergestellt wird.
2. Kontakt nach Anspruch 1, dadurch gekennzeichnet, daß die Zähne (11) schräg abgeschnitten sind.
3. Kontakt nach einem der vorhergehenden Ansprüche dadurch gekennzeichnet, daß die Enden der Arme (6 und 7) des V der Zungen zugespitzt sind.
4. Kontakt nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß mindestens eine Zunge mit einer Neigung in Richtung auf den Kontakt umgebogen ist.
5. Kontakt nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß zwei Zungen (2, 3) vorgesehen sind, und daß jeder Flügel drei vorstehende Zähne (11) aufweist, die beiderseits der Zungen im Wechsel mit den Auschnitten (10) angeordnet sind.
