Definitions

  • the present invention relates to electrical connectors and more particularly to electrical connectors within which noise filter means are incorporated.
  • an outer insulative housing In the modular jack of the present invention, there is an outer insulative housing. An interior medial wall projects upwardly from the bottom wall of this housing. The housing has open front and rear ends and a ferrite element is positioned over part of the open rear end and against the interior medial wall. An elongated insulative insert is positioned over the top end of the ferrite element and extends into the interior of the housing.

Abstract

L'invention se rapporte à un ensemble douille modulaire à filtre, comprenant un boîtier isolant externe (10) doté de faces avant et arrière ouvertes. Un élément en ferrite (72), à fils verticaux conducteurs (86, 88), est placé à proximité de l'extrémité postérieure, et une pièce rapportée isolante allongée (94) est superposée à l'élément en ferrite. Cette pièce isolante est fixée au boîtier, les fils conducteurs s'étendant verticalement depuis l'élément en ferrite, au-dessus du côté supérieur de la pièce rapportée, jusqu'à sont extrémité, puis se recourbant vers le bas et vers l'arrière afin de venir en appui sur la surface supérieure d'une paroi médiane interne du boîtier. Un procédé d'assemblage d'une douille à caractéristique de filtrage du bruit est également décrit.
