Definitions

• the present invention relates to a connector for high amperage electrical bushing.
• MBE Epitaxy by molecular jet
• epitaxial layers are obtained by transporting a material, containing the constituent elements of the layer to be formed, to a substrate, metallic or semiconductor, where it is adsorbed. This material transport is carried out in a vacuum chamber and preferably under ultra-vacuum, ie at a pressure of less than 10 "9 mbar in order to obtain films free of any contamination.
• the most common source of material for this molecular beam epitaxy is evaporation from a Knudsen type source. It is then a crucible heated by the Joule effect.
• the crucible which can be made of boron nitride or high purity graphite, for example, has a cylindrical or conical shape.
• the Joule effect is generally obtained by the use of a resistant element, for example a filament.
• a resistant element for example a filament.
• temperatures above 1000 ° C are necessary, which involves injecting a strong current into the resistive element.
• a chain of suitable elements is therefore necessary to deliver the required current to the resistive element.
• Electrical bushings 1 with high amperage for example at least of the order of 50 A are thus used to establish a connection between the resistive elements situated inside the vacuum enclosure and the outside of the enclosure where the generators are placed ( Figure 1).
• Electric cables 2 of appropriate section, for example, 10 mm 2 for a current I between 35 and 50 A, ensure the connection between these generators and the electrical bushings 1.
• Electrical connectors 3 with copper lugs are used to make the connection between the high-amperage electrical bushings and the power cables 2.
• this type of connection does not allow easy manipulation of the power cables 2.
• the mounting / dismounting of the power cables 2, for example to change a cell requires the screwing / unscrewing of screws 5 at the level of the thimble 3.
• the electrical bushing 1 is then subjected to torsions which can result in a loss of tightness of said bushing 1.
• any action on the electrical connectors 3 with thimble implies a problem of electrical safety for the user because this manipulation requires the removal of any electrical insulation.
• the objective of the present invention is to provide a connector for electrical crossing with high amperage, simple in design and economical, being excellent conductor while allowing easy handling of the power cables as well as high protection for the user. .
• the invention relates to a connector for high amperage electrical bushing comprising at least one pin having a first main axis, comprising a first assembly comprising a socket having a second main axis, said socket being intended to be fixed on a cable electric, and a first insulator intended to cover at least partially the socket.

• An object of the present invention is the production of a connector 10 for electrically connecting a power cable to an electrical bushing 11 with high amperage. These bushings 11 are well known and allow electrical connections to be made between elements placed in a closed volume and a generator located outside this volume.
• This crossing electric 11 comprises at least one spindle 12 having a first main axis 13 and of diameter d.

It further comprises a part 19 comprising a recess 20 centered on the second main axis 16 and of diameter d intended to surround the pin 12 of the electrical bushing 1 1 when the electrical connection is established between said cable 17 and said bushing 1 1.
• This socket 15 is produced in a very good conductive material with low contact resistance, preferably high quality copper, silver.
• Said first assembly also comprises a first insulator 21 intended to cover at least partially the sleeve 15. In a preferred embodiment, said insulator 21 completely covers the sleeve 15 with the exception of said recesses 18, 20 serving to receive the pin 12 or the power cable 17.
• the first assembly further comprises a cap 22 comprising a first recess 23 centered on the second main axis 16 of the sleeve and locking means 24 for fixing the cap 22 on the first insulator 21.
• a cap is used here to mean a piece of insulating material comprising a wall 25 integral with a bottom 26. The internal diameter D of this piece is at least equal to the external diameter of the first insulator 21 so that after fixing the cap 22 on the first insulator 21, this then partially covers said insulator.

• the internal diameter D of the cap 22 is less than the external diameter of the first insulator 21 so that the cap 22 is fixed to said first insulator 21 by stamping.
• the inside diameter of the second insulator 28 is equal to or greater than the outside diameter of the first insulator 21 so that the first set can be freely inserted or removed from the second set.
