Definitions

  • the invention relates to a device for coding a Connector with pin contacts, a connector with pin contacts and a mating connector with closable openings for coding pins is provided and the connector corresponding to the unlocked Set the mating connector coding pins has in the assembled state in the openings protrude into the mating connector.
  • Such a device is e.g. by EP 0179999 A2 known.
  • This type of coding has the disadvantage that in addition to the pin field for the connectors additional space is needed for connection purposes cannot be used.
  • the invention is based, a less complex task and to create a space-saving coding device.
  • the support sleeve sits on the bottom of the connector housing. She is considerably more resistant to kinks than the pin contact. A try with an assembly in the wrong slot causes that the assembly is not even with increased effort can be inserted more without the pin contact or the support sleeve is damaged.
  • the support sleeve can e.g. be hollow cylindrical, the inner diameter is slightly less than the diagonal thickness of the pin contact. As a result, the support sleeve is held clamped on the pin contact.
  • the training according to claim 4 can be squeezed the support sleeve between two crimping jaws in a simple manner realize.
  • a connector 1 is equipped with pin contacts 2.
  • the pin contacts 2 are designed so that with Socket contacts of a mating connector, not shown are contactable.
  • pin contacts 2 can be used for coding purposes.
  • the pin contacts 2 serving as coding pins are provided with support sleeves 3 amplified, which are axially attachable to the pin contacts 2 according to the arrow shown. They are provided with two pairs of diametrically opposite notches 4, 5, which oval deform the cross section of the cylindrical support sleeves 3 at these points.
  • the outer notches 5 are adjacent to the free pin end, the inner notches 4 are arranged at the other end of the support sleeve 3. These are supported on the base of a housing 6 of the connector 1 and enclose the pin contacts 2 over their entire length. From the figure it can be seen that the two pairs of notches 4 and 5 are angularly offset from one another.
  • the cross section of the support sleeve 3 is in the area the inner notches 4 shown.
  • the support sleeve 3 is deformed into an approximately oval cross-section, where the small semiaxis of the inner ellipse is larger than the thickness of the pin contact 2.
  • the support sleeve 3 is opposite the pin contact 2 rotated so far that two opposite longitudinal edges of the Pin contact 2 touch the inner wall of the notches 4.
  • FIG. 5 shows the cross sections of the two notches 4 and 5. They form two elliptical oval zones, whose large semiaxes in their angular position by approx. 35 Degrees to each other about the central axis of the pin contact 2 are. The points of contact with the longitudinal edges of the Pin contact 2 are thus clockwise or counterclockwise to the side of the small semiaxes so that the pin contact 2 twisted accordingly between the two notches 4 and 5 becomes. There is a permanent elastic clamping effect between the pin contact 2 and the support sleeve 3, whereby a secure mutual liability is guaranteed.

Claims (6)

  1. Dispositif pour coder un connecteur (1) à contact (2) à broche, un connecteur à contacts à broche et un dispositif à fiches conjugué étant muni d'ouvertures pouvant être fermées pour des broches de codage et le connecteur (1) comportant de manière correspondante aux emplacements du dispositif à fiches conjugué qui ne sont pas fermés des broches de codage qui, à l'état assemblé, pénètrent dans les ouvertures du dispositif à fiches conjugué, caractérisé en ce que les broches de codage sont réalisées comme des contacts (2) à broche prévus pour produire la liaison d'enfichage et de section transversale rectangulaire, sur lesquels sont enfichées, pour le codage, des douilles (3) de soutien qui prennent appui sur le boítier (6) du connecteur (i) et qui sont maintenues bloquées avec possibilité de coulissement sur les contacts (2) à broche.
  2. Dispositif suivant la revendication 1, caractérisé en ce que la douille (3) de soutien est munie d'au moins une entaille (4, 5) sur laquelle la douille (3) de soutien est bloquée sur le contact (2) à broche.
  3. Dispositif suivant la revendication 2, caractérisé en ce que les entailles (5) sont constituées de deux déformations du genre de moulures diamétralement opposées, qui sont disposées à l'extrémité extérieure, tournées vers le dispositif à fiches conjugué, de la douille (3) de soutien et entre lesquelles le contact (2) à broche est bloqué.
  4. Dispositif suivant la revendication 2 ou 3, caractérisé en ce que la douille (3) de soutien cylindrique a, dans la zone des entailles (4, 5) une section transversale ovale du genre d'une ellipse.
  5. Dispositif suivant la revendication 3 ou 4, caractérisé en ce qu'il est prévu à l'extrémité intérieure de la douille une deuxième paire d'entailles (4) dont la largeur bloquante est un peu plus grande que l'épaisseur correspondante du contact (2) à broche de section transversale rectangulaire, en ce que la largeur bloquante des deuxièmes entailles (4, 5) est inférieure à l'épaisseur en diagonale du contact (2) à broche et en ce que les entailles (4) intérieures sont prévues en étant tournées autour de l'axe médian de la douille (3) de soutien, par rapport aux entailles (5) extérieures, jusqu'à ce que les entailles (4, 5) se déforment en se tordant sur les grands côtés du contact (2) à broche.
  6. Dispositif suivant l'une des revendications précédentes, caractérisé en ce que les entailles (5) extérieures ont les mêmes dimensions de section transversale que les entailles (4) intérieures.
