Definitions

  • the invention relates to a connector comprising an electrically insulating connector housing, which is formed from a plurality of housing parts, at least one disposed in a receiving space of the connector housing contact element, which is accessible via a plug opening for a contact element of a complementary connector, and via a cable opening in the connector housing leading electrical cable whose electrical conductor is connected to the contact element.

  • the joints between the receiving spaces of the connector housing also are cohesively closed, so that here too no leakage currents can pass from one receiving space to the other through the joints, but also in this case, the leakage currents must extend either via the plug opening and / or the cable opening.

Abstract

L'invention concerne un connecteur enfichable comprenant un boîtier de connecteur enfichable configuré de manière électriquement isolante et composé de plusieurs pièces de boîtier, au moins un élément de contact, qui est placé dans un logement du boîtier de connecteur enfichable et qui est accessible à un élément de contact d'un connecteur enfichable complémentaire par l'intermédiaire d'une ouverture d'enfichage, et un câble électrique qui est introduit dans le boîtier de connecteur enfichable par une ouverture de câble et dont le conducteur électrique est relié à l'élément de contact. Afin d'améliorer le connecteur enfichable de manière que le boîtier de connecteur enfichable puisse être aussi compact que possible tout en offrant des lignes de fuite aussi grandes que possible, il est proposé que les joints entre les pièces du boîtier qui sont adjacents au logement soient fermés par fusion de la matière et que, de cette manière, les lignes de fuite partant de l'élément de contact dans le logement aillent exclusivement vers l'ouverture d'enfichage et/ou l'ouverture du câble.
