Definitions

  • the invention relates to a connector for Cageclamp connection technology, which is made in one piece as a stamped and bent part and which has a first leg for receiving a tension spring and a second leg for contacting.
  • a generic connector according to FIG 4 is used for terminal blocks.
  • the tension spring is supported by support lugs angled laterally on the first leg and thus protected against incorrect operation in such a way that the actuating tool is inserted into the wire insertion opening and the tension spring is thus bent.
  • the laterally angled support tabs are in turn supported in the housing.
  • the connector designed in this way is relatively expensive to manufacture due to the high cost of materials.
  • the invention has for its object to improve a connector of the type mentioned above so that it can be manufactured with little material loss.
  • the object is achieved in that a locking lobe is removed from the first leg and the first leg is angled in the opposite direction.
  • FIG 2 shows the connector according to FIG 1 in a front
  • FIG. 3 shows a perspective view of the connector according to FIG.
  • FIG. 1 shows a section of a contactor housing, which is composed of an upper part 1, a lower part 2 and a cap 14.
  • the connector 3 is mounted for cage clamp connection technology.
  • the connector 3 carries two cage tension spring 4, for their actuation when connecting a conductor in the cap 14 an opening 5 for carrying out a tool, e.g. a screwdriver is provided.
  • the cap 14 is provided with a line feed opening 6.
  • the connector 3 shown in a side view in FIG. 2 is made in one piece as a stamped and bent part and consists of a first leg 7, which has 2 horn-shaped receptacles 8 at its end, and a second leg 9, which is angled at almost a right angle to it, for con - tacting serves.
  • Two cage tension springs 4 can be clamped onto the first leg 7.
  • a flap 10 which has been sheared between the horn-shaped receptacles 8 (see FIG. 3) is bent opposite to the direction of the second leg 9.
  • This tab 10, which serves to support the cage tension springs 4, can be produced without waste.
  • From the first leg 7, a locking tab 11 is also smoothly sheared out of the middle and angled in the opposite direction to the first leg 7.
  • the second leg 9 is in his
  • the assembly of the connector 3 in the contactor housing is carried out by first inserting the connector 3 with its second leg 9 into a groove 12 in the upper part 1 and then installing the lower part 2 from below, locking over the locking tabs 11.
  • the deformation 13 ensures that the connector 3 is seated in the groove 12 without play.
  • a punctiform press fit results, the plastic of the housing giving way.
  • the horn-shaped receptacles 8 are supported on the cap 14 of the contactor housing, so that when the cage tension spring 4 is actuated, plastic deformation due to the bending moment on the first leg 7 of the connecting piece 3 is prevented.
  • the connector 3 described can be manufactured inexpensively due to the low material consumption. Such connectors are usually manufactured from a stamped strip. The cost savings due to lower material consumption are particularly high if the connecting pieces are rolling seam welded contact pieces, in which the stamped strip is welded continuously with a silver strip. This is because the punching waste is coated with silver.

Abstract

La présente invention concerne une pièce de raccord (3) fabriquée d'une seule pièce sous forme de pièce pliée à la presse, présentant une patte (9) de contact et une autre patte prévue pour recevoir un ressort de traction (4), d'où des languettes (10. 11) sont découpées et coudées. Ces languettes (10, 11) servent à protéger le ressort de traction (4) fixé par pression lorsque l'on utilise un raccord conducteur non conforme, et à bloquer la pièce de raccord (3) lors du montage dans le boîtier.
