Abstract

An electrical isolation device including a support with thickness E including two faces facing one another, referred to, respectively, as the two faces having a length L, a width l; on each face of the support, a plurality of voltage dividers is positioned extending over the length, each voltage divider including electrical components that are connected in series and arranged according to a first and a second stage, each first stage including a row of even components and a row of odd components, the rows being parallel, and adjacent, and the second stage corresponding to a linear arrangement of components.

First claim

The invention claimed is:

1. An electrical insulation device comprising:
a support with thickness E comprising two faces facing one another, referred to, respectively, as front face and rear face, the two faces having a length L, a width l;
on each face of the support, a plurality of voltage dividers is positioned extending over the length L of said face, each voltage divider comprising electrical components that are connected in series and arranged consecutively according to a first and a second stage, each first stage comprising a row of even electrical components and a row of odd electrical components, the two rows being parallel along the length L, and substantially adjacent along the width l, and each second stage corresponding to a linear arrangement of the electrical components.

2. The device according to claim 1 , wherein for each of the rows of even electrical components and the rows of odd electrical components the spacing along the length L between two electrical components of a same row is less than the spacing needed for the insertion of an electrical component.

3. The device according to claim 1 , wherein the spacing along the width l of the rows of even electrical components and the rows of odd electrical components arranged on a same face is regular, said spacing being less than a spacing needed for insertion of an electrical component.

4. The device according to claim 1 , wherein in each of the rows of even and odd electrical components the arrangement of said electrical components is regular along a step T in the direction of the length L.

5. The device according to claim 4 , wherein the rows of even electrical components of the two faces of the support are in phase with each other, and the rows of odd electrical components of the two faces of the support are likewise in phase with each other, the rows of even electrical components have an offset along the length L with respect to the rows of odd electrical components, the offset being that of a half-step T/2.

6. The device according to claim 1 , wherein the support comprises an armouring layer inserted between two layers of electrical insulator, and disposed substantially parallel to the two faces of the support, the armouring layer being adapted to reduce the crosstalk between electrical components facing each other across the thickness E of the support.

7. The device according to claim 6 , wherein the armouring layer extends only over a first surface, the first surface being the surface facing the surface occupied by the first stages on the front face and the rear face.

8. The device according to claim 7 , wherein two first stages each disposed on a different face of the support can have only a single row of electrical components facing each other across the thickness E of the support, so that at least one row of components on one of the two faces is not facing any row disposed on the other face, the armouring layer extends only over a second surface, the second surface being limited to the projection along the direction E of the surface occupied by the rows of the front face each facing a row of the rear face.

9. The device according to claim 1 , wherein the second stages of the front and rear faces are arranged in parallel with each other along the length L, the second stages of the front face being staggered along the width l in relation to the second stages of the rear face such that no electrical component of the second stages of a face is facing, even partially, another electrical component arranged on the other face.

10. The device according to claim 1 , wherein the second stages of the voltage dividers comprise one free end designed to be connected to a source of low voltage.

11. The device according to claim 1 , wherein the first stages of the voltage dividers each comprise one free end designed to be connected to a voltage measuring device.

12. The device according to claim 1 , wherein the electrical components of the voltage dividers form a printed circuit board with the support.

13. The device according to claim 1 , wherein all the electrical components of all the voltage dividers are identical, and the electrical components are electrical resistors.

14. The device according to claim 1 , wherein the support comprising the voltage dividers furthermore comprises a moulding and an overmoulding designed to provide an electrical insulation and a mechanical strength of the device.

15. The device according to claim 14 , wherein the device is provided with fixation on a rail.

16. The device according to claim 15 , wherein the rail is a DIN rail.
