Definitions

  • the invention relates to a shielded electrical subrack with a rear wall wiring, the contact pins for plug-in connectors on the rear e.g. of cable connectors, the connectors being covered by a shield plate which is provided with circumferential, feathered spring contacts which can be contacted with grounded contact pins of the rear wall wiring.
  • Such a structure is e.g. become known through the documents of the German utility model G 90 15 255. Due to the narrow distribution of the grounded contact pins, they form an additional shielding jacket that bridges the distance between the cable connector and the rear wall wiring plate.
  • the invention has for its object to improve the contact with the contact pins and the shielding effect.
  • the shielding plate on the back of the backplane wiring plate shields unshielded wires within the subrack.
  • these individual wires were previously only protected by the rear wall of a housing cabinet in which the subrack is inserted. This could cause interference radiation between the individual subracks occur.
  • the shield plate is provided with openings at all points where plugs can be arranged. Openings that are not occupied can be closed, for example, with cover caps which are designed similarly to the shielding jacket of the plug connection.
  • the contact pins are now supported on the inner wall of the opening, they can no longer deflect when the connector is plugged in and when the feathered contact tongues meet the contact pins. This increases the contact force between the contact tongues and the contact pins, as a result of which better contacting is achieved. This already gives a better shielding effect. This is further improved in that a direct contact is made between the grounded contact pins and the shield plate.
  • the grounded contact pins are contacted with at least one shield layer of a backplane wiring board. This creates a close-knit ground connection between the connector shield, the shield plate and the ground layers of the rear wall wiring, which increases the overall shielding even further.
  • a multi-pin connector 1 is attached to a circuit board 2 to which e.g. one or more cables can be connected.
  • the connector has a feathered shield jacket 3, which largely encloses the connector 1 with the exception of its plug side.
  • the shield jacket 3 is made of strip material which is provided with a bulge extending in its longitudinal direction. This has a multiplicity of closed transverse slots 5, between which the shield jacket 3 forms leaf-spring-like contact tongues 4, which essentially extend in the insertion direction.
  • the contact tongues 4 are located near the plug side of the connector 1.
  • the connector 1 is plugged into contact pins 7 of a backplane wiring board 8.
  • the contact tongues 4 are located in the vicinity of contact springs 9 of the connector 1 and are contacted with adjacent earth contact pins 10 of the backplane wiring board 8.
  • the earth contact pins 10 are extended beyond the contact pins 7.
  • a shield plate 11 of the assembly frame extends above the ends of the contact pins 7. This is provided with openings 12 for the connector 1 and the adjacent earth contact pins 10. These protrude into the openings 12 and rest on the inner wall thereof.
  • the contact tongues 4 rest against the earth contact pins 10 under spring tension from the opposite side, so that they are pressed accordingly against the inner wall of the openings 12.
  • the earth contact pins 10 are in contact with ground layers 13 of the rear wiring plate, which creates a close-knit connection between the shield shell 3, the shield plate 11 and the rear wall wiring plate 8.

Abstract

Un châssis électrique blindé présente sur sa face arrière une tôle de blindage (11) munie de trous (12) pour connecteurs multiples blindés (1) à enficher à l'arrière. Chaque connecteur multiple est muni d'une enveloppe de blindage (3) à lames de contact (4) faisant ressort, en contact avec les broches de prise de terre périphériques (10) d'une plaque de câblage (8) du panneau arrière. Les broches de prise de terre (10) font saillie dans les trous (12) de la tôle de blindage (11) et sont pressées par les lames de contact (4) contre leur paroi intérieure. Ainsi s'établit une mise à la masse avec un faible espace libre, entre le connecteur multiple (1), la tôle de blindage (11) et le câblage du panneau arrière (8).

Claims (2)

  1. Châssis électrique blindé comportant un câblage arrière, qui comporte des broches (7) de contact pour des connecteurs (1) multiples pouvant être enfichés à l'arrière, par exemple des fiches de câbles, les connecteurs (1) multiples étant entourés d'une gaine (3) de blindage, laquelle est munie de languettes (4) de contact de type ressort à lame sur le pourtour, ces languettes de contact pouvant entrer en contact avec des broches (10) de contact à la terre d'une plaquette (8) du câblage arrière,
    caractérisé en ce que
    le châssis comporte une tôle (11) de blindage, qui recouvre le câblage arrière et qui est munie de trous (12) de passage pour le connecteur (1) multiple, les broches (10) de contact à la terre pour les languettes (4) de contact pénètrent dans les trous (12) de passage et peuvent y être repoussées par les languettes (4) de contact sur les parois intérieures des trous (12) de passage.
  2. Châssis suivant la revendication 1,
    caractérisé en ce que
    les broches (10) de contact à la terre sont en contact avec au moins une couche (13) de masse de la plaquette (8) du câblage arrière.
