Claim 3

A plug according to claim 1 wherein said core comprises a ferromagnetic stud connecting said electrically conductive element to said arc extinguishing member.

Claim 4

An electrical connector for disconnecting high voltage conductors comprising a receptacle having a first electrically conductive element having one end connected to a high voltage conductor and a first member made of an arc-extinguishing material positioned at the other end of said first element, a plug having a second electrically conductive element having one end connected to a high voltage conductor and a second member made of an arc-extinguishing material positioned at the other end of said second element, and a magnetically permeable core embedded within said second member for influencing the flow path of the arc drawn between said first and second elements on disconnection of said plug from said receptacle.

Claim 5

An electrical connector for disconnecting high voltage conductors comprising a receptacle having a first electrically conductive element having one end connected to a high voltage conductor and a first member made of an arc-extinguishing material positioned at the other end of said first element, a plug having a second electrically conductive element having one end connected to a high voltage conductor and a second member made of an arc-extinguishing material positioned at the other end of said second element, and a magnetically permeable core embedded within said second member for influencing the flow path of the arc drawn between said first and second elements on disconnection of said plug from said receptacle.

Claim 6

An electrical connector according to claim 3 wherein said core comprises a ferromagnetic stud.

Claim 7

An electrical connector for connecting high voltage conductors comprising an electrically insulating plug having a tubular electrically conductive element connected to one of the high voltage conductors, a ferromagnetic stud secured to the end of said element and forming an extension thereof and a member of arc-extinguishing material mounted on said stud, an electrically insulating receptacle having a hollow electrically conductive element connected to another of the high voltage conductors and a sleeve of arc-extinguishing material positioned at the entry to said hollow element to telescopically receive said tubular element and arc-extinguishing member on connection of said plug and receptacle.

Claim 8

An electrical connector for connecting high voltage conductors comprising an electrically insulating plug having a tubular electrically conductive element connected to one of the high voltage conductors, a ferromagnetic stud secured to the end of said element and forming an extension thereof and a member of arc-extinguishing material mounted on said stud, an electrically insulating receptacle having a hollow electrically conductive element connected to another of the high voltage conductors and a sleeve of arc-extinguishing material positioned at the entry to said hollow element to telescopically receive said tubular element and arc-extinguishing member on connection of said plug and receptacle.

Claim 9

The combination of a telescopically insulated cable connector having disconnectable male and female electrical contacts electrically connected to high voltage conductors, the female contact having a first member of arc-extinguishing material positioned at the entry to said female contact, the male contact having a second member of arc-extinguishing material affixed to the end of the male contact, and a magnetically permeable element embedded in one of said first and second members to aid in extinguishing the arc drawn between said contacts on separation.

Claim 10

The combination of a telescopically insulated cable connector having disconnectable male and female electrical contacts electrically connected to high voltage conductors, the female contact having a first member of arc-extinguishing material positioned at the entry to said female contact, the male contact having a second member of arc-extinguishing material affixed to the end of the male contact, and a magnetically permeable element embedded in one of said first and second members to aid in extinguishing the arc drawn between said contacts on separation.
