Abstract

The invention relates to an electrically and thermally connecting device ( 3 ) for batteries and pieces of electrical distribution equipment of an aircraft, comprising a casing ( 5 ) containing a plurality of bare under-voltage parts ( 7 ), said connecting device ( 3 ) being intended to make contact with a portion of the casing ( 5 ) and at least one bare under-voltage part ( 7 ), said connecting device ( 3 ) furthermore comprising: at least one base ( 11 ) that is made from a thermally conductive material and that is intended to be fastened to the portion of the casing ( 5 ); at least one head ( 13 ) that comprises a springback connector and that is intended to make contact with the bare under-voltage parts ( 7 ) and the portion of the casing ( 5 ); and an intermediate element ( 15 ) that is intended to electrically connect the bare parts ( 7 ), said element ( 15 ) being clamped between a base ( 11 ) and a head ( 13 ). The invention also relates to a battery and to a piece of electrical distribution equipment for an aircraft.

First claim

The invention claimed is:

1. An electrically and thermally connecting device for batteries and pieces of electrical distribution equipment of an aircraft comprising a casing containing a plurality of parts made of an electrically conductive material which conveys an electrical charge without electrically insulating protection on a visible area of live parts, said connecting device being designed to be in contact with a part of the casing and at least one live part, said connecting device comprising:
at least one base which is made of a thermally conductive material, and is designed to be secured on the part of the casing or is designed to be secured on the at least one live part;
at least one head which comprises a resilient return connector, and is designed to put the live parts and the part of the casing into contact;
an intermediate element which is designed to connect the live parts electrically, said element being clamped between the base and the head, the base and the head being in contact with elements of a different nature,
wherein the resilient return connector comprising one or more spring strips.

2. The device as claimed in claim 1 , wherein the base is made of a ceramic material.

3. The device as claimed in claim 1 , wherein the resilient return connector comprises a support on which the strip(s) is/are secured, said support being made of aluminum or of copper.

4. The device as claimed in claim 1 , wherein the base is a wedge disposed between the intermediate element and the part of the casing.

5. The device as claimed in claim 1 , wherein the base covers a securing means of the resilient return connector.

6. The device as claimed in claim 1 , wherein the intermediate element is a substantially flat bar made of an electrically conductive material.

7. The device as claimed in claim 6 , wherein the electrically conductive material includes aluminum or copper.

8. The device as claimed in claim 1 , wherein the intermediate element comprises a central part which is glued onto the part of the casing by means of a dielectric insulating film, and at least one end which is clamped between the head and the base.

9. A piece of electrical distribution equipment for an aircraft comprising a casing, at least one electrical power component, and live parts, and a connecting device which ensures the electrical and thermal connection as claimed in claim 1 .

10. The piece of electrical distribution equipment as claimed in claim 9 , wherein the casing comprises a cover which is mobile relative to a body containing the live parts, the connecting device ensuring the electrical and thermal connection of each electronic contact and of the cover.

11. An aircraft battery comprising a casing and at least two cells contained in said casing, said battery comprising at least two connecting devices as claimed in claim 1 .

12. The aircraft battery as claimed in claim 11 , wherein the casing comprises a cover which is mobile relative to a body containing the at least two cells, the connecting device ensuring the electrical and thermal connection of each cell and of the cover.
