DETAILED DESCRIPTION

(6) As illustrated on FIG. 1, an electrical apparatus 1 such as a terminal block 3 comprises a conducting bar 5. The terminal block 3 has two insertion orifices 7a, 7b, each arranged for receiving a conductor. Connectors 10 are coupled to the terminal block 3.

(7) The conducting bar 5 comprises a part 11 having two contact plugs 13a, 13b arranged to be in contact when a conductor is inserted in the corresponding insertion orifice 7a, 7b.

(8) As illustrated on FIGS. 2 and 3, the part 11 of the conducting bar 5 has a longitudinal extension direction 15 according to a determined length as depicted by reference 11 in FIG. 3, the first contact plug 13a and the second contact plug 13b extending transversally to the extension direction 15 of the part 11 of the conducting bar 5.

(9) The first contact plug 13a and the second contact plug 13b are also disposed in a parallel manner and are symmetrical with respect to a plane 17 transversal to the extension direction 15 of the part 11 of the conducting bar 5.

(10) The part 11 of the conducting bar 5 comprises a first planar portion 19 extending along a first plane 21, a second planar portion 23 extending along a second plane 25 and a third planar portion 27 extending along a third plane 29. Each portion 19, 23, 27 are extending according to the determined length along the extension direction 15.

(11) The second plane 25 and the third plane 29 are parallel and both perpendicular to the first plane 21. The part 11 of the conducting bar 5 comprises an adjoining edge 31 of the first portion 19 with the second portion 23 and an adjoining edge 33 of the first portion 19 with the third portion 27. The adjoining edges 31, 33 extend along the extension direction 15 of the part 11 of the conducting bar 5.

(12) As illustrated on FIG. 4, the first portion 19, the second portion 23 and the third portion 27 originate from a same planar base 35. The base 35 is a cutout plate, the part 11 of the conducting bar 6 having been obtained by folding along the extension directions of the adjoining edges 31, 33.

(13) It thus appears that the width 37 of the base 35, defined transversally to the extension direction 15 of the part 11 of the conducting bar 5, substantially corresponds to the sum of the widths of the first portion 19, of the second portion 23 and of the third portion 27.

(14) The first contact plug 13a and the second contact plug 13b both originate from the first portion 19.

(15) A first cutout 43 along a first open contour 39 is produced in the planar base 35. This first open contour 39 has a rectangular form, the first cutout 43 being produced over two lengths and a width of the rectangle.

(16) A first folding axis 41 is defined as being substantially superimposed to the width of the non cutout rectangle. The first contact plug 13a hence originates from folding the first cutout 43 of the first portion 19. The first cutout 43 is defined as being the inner part to the first contour 39.

(17) The second contact plug 34b, similarly, originates from folding a second inner cutout 45 to a second open contour 47. Then are also achieved the second cutout 45 then a folding along a second folding axis 49.

(18) The comparison of the part 11 of the conducting bar 5 and the base 35 of which the part 11 of the conducting bar 5 originates allows distinguishing the advantages of the present invention.

(19) The base 35 is substantially rectangular. This allows an easy disposition on a plate in which a plurality of bases 35 must be cut out. The plate off-cuts are thereby reduced.

(20) In fact, the orientation of the second contour 47 producing the second contact plug 13b does not go over the rectangular shape of the base 35.

(21) This is due to the disposition of the first contour 39 and the second contour 47 which produces the contact plugs 13a, 13b. The fact that these cutouts 43, 45 are symmetrical with respect to a transversal plane 17 allows maintaining the rectangular shape of the base while obtaining a part 11 of the conducting bar 5 of which the contact plugs 13a, 13b are spaced apart sufficiently to be suitable for the terminal block 3.

(22) In fact, if the cutouts were produced in the same direction along the extension direction 15 of the part 11 of the conducting bar 5, the base 35 would have an extension 51 outside the current contour of the base 35 as represented in dots on FIG. 4.

(23) As it is known per se, the invention is not limited to the sole embodiment of this part of the conducting bar, described above by way of example, it encompasses all the variants.
