Definitions

  • the invention relates to a shielded, a metal screen housing having connector, connection side is connected at least one shielded cable to the plug side and a collar comprising a metal plug Direction • or female insert is provided.
  • a plug connector is known from DE-GM 87 13 046.
  • the plug connector as the link between closed electronic systems and the periphery is subject to increasingly higher requirements with regard to electromagnetic compatibility.
  • the development of electronic systems is characterized by an ever increasing processing speed, ie by higher clock frequencies in digital computing and control systems. This increases the sensitivity to high-frequency interference. These interferences can lead to malfunctions which have a direct effect on the quality of these systems.
  • interference also comes from electronic systems or devices themselves, which work with steep-edged, high-frequency signals in the control and power sections.
  • the: connector as an interface element between a closed electronic system and the environment is of decisive importance.
  • the connector known from DE-GM 87 13 046 is provided for such purposes.

  • the metal housing of the connector is made in one piece and with one shell.
  • the contact between the cable shield and the housing of the connector is made by a direct end contact, ie the cable shield is not only partially or via intermediate transitions as with screwed-on clamps, but all around and without intermediate transitions in direct contact with the shield housing.
  • front-side contacting from the housing of the connector to a device wall is provided, so that an unimpeded flow of surface currents is ensured.

  • the inner width of the shield housing at the plug end is selected so that one is attached to a device wall
  • Plug connector of the plug or socket insert whose mating connector on the device wall and the passage opening of the device wall are laterally surrounded by the plug-side housing edge. This encapsulates the plug or socket insert and mating connector as well as the recess in the device wall in an electrically shielded manner.
  • a contact plate is arranged between the plug-side end face of the dish housing and the device wall.
  • a contact plate can e.g. consist of a feathered spring plate.
  • the cable is expediently connected by means of a connector.
  • Connection area of the shield housing screw-in union nut can be made produce the cable shield on the transverse wall of the shield housing in a simple manner by sliding a sleeve over the exposed cable shield, over which the cable shield is turned over on one side by 180 ° and on which the union nut engages on the other side.
  • the plug connector can only be inserted freely after connecting to the mating connector and without being influenced by the fastening process manufactured connector are then locked by means of the fasteners.

Abstract

Afin de satisfaire des exigences élevées de blindage, le boîtier métallique (1) de blindage d'un connecteur à fiches est formé en une seule pièce et en une seule enveloppe, et la pièce d'insertion à fiches mâles ou à douilles (6) est en retrait vers l'intérieur, de sorte que le contact avec une paroi (8) de l'appareil ne se fait que par la face frontale (7) du boîtier (1) de blindage située du côté du connecteur, alors que le blindage (25) du câble est directement en contact du côté frontal avec une paroi transversale (22) du boîtier de blindage (1). On obtient ainsi un connecteur à fiches ayant un minimum de points de transition, de sorte que les courants de surface peuvent s'écouler sans obstacle. L'invention est utile dans des connecteurs à fiches de basse fréquence, notamment dans les boîtiers de blindage de connecteurs à fiches subminiatures.
