Claim:
1. An electrical connector configured to provide a sealed electrical link between an inside environment subjected to corrosive gases or liquids under a first pressure and an outside environment of a second pressure, the electrical connector comprising: a connector body configured to be hermetically secured to a pressurized enclosure separating the inside environment and the outside environment to create a pressure barrier with an outside of the pressurized enclosure and comprising gastight feed-throughs configured to receive electrical contacts connecting said outside environment to said inside environment; conductor cables connected to said electrical contacts within said inside environment, each conductor cable comprising an outer insulating layer, the outer insulating layer comprising a fusible thermoplastic material; a thermoplastic insulator surrounding said conductor cables and secured to said connector body, at least a portion of said thermoplastic insulator comprising the fusible thermoplastic material; a thermoplastic weld based on a localized fusion between said at least a portion of said thermoplastic insulator and said outer insulating layers of said conductor cables, wherein the thermoplastic weld is configured to protect the connection between the conductor cables and electrical contacts from moisture crossing the pressure barrier; a space defined by a separation between the connector body and the thermoplastic insulator comprising a supply of insulating oil held captive between said connector body and said thermoplastic insulator, wherein the thermoplastic insulator constitutes a removable sealing element, secured with respect to the connector body by a screw-fastening element, that enables the connector body to remain hermetically secured to the pressurized enclosure when protection of the connection fails; and a cover secured to said connector body, wherein the cover is the screw-fastening element.
