Abstract

The present invention relates to a start system ( 1 ) comprising a plurality of electrical apparatuses ( 3, 5 ) each comprising an insulating casing ( 7, 9 ), secured to each other and having an alignment along a first extension direction (D 1 ). The plurality of electrical apparatuses ( 3, 5 ) is intended to be brought on a plurality of securing rails ( 13, 15 ) extending along a second extension direction (D 2 ) transversal to the first extension direction (D 1 ). A first electrical apparatus ( 3 ) comprises a removable mounting device ( 21 ) including a primary movable mounting element ( 17 ), the mounting device ( 21 ) forming a primary housing ( 35 ) in which a portion ( 13 a ) of a first rail ( 13 ) is able to be inserted. A second electrical apparatus ( 5 ) comprises a secondary mounting element ( 19 ), the secondary mounting element ( 19 ) forming, with the insulating casing ( 9 ) of the second electrical apparatus ( 5 ) a secondary housing ( 81 ) in which is able to be inserted a portion ( 15 a ) of a second rail ( 15 ).

First claim

The invention claimed is:

1. A start system intended to be brought on a plurality of securing rails, the start system comprising a first electrical apparatus being intended to collaborate with a first securing rail from among the plurality of securing rails, and a second electrical apparatus being intended to collaborate with a second securing rail from among the plurality of securing rails and intended to be mounted with the first electrical apparatus and electrically connected to the first electrical apparatus in such a manner as to form the start system, the first electrical apparatus and the second electrical apparatus being aligned along a first extension direction (D 1 ),
the first electrical apparatus comprising a first insulating casing and a mounting device secured to the first insulating casing, the mounting device comprising:
a support intended to be brought on the first electrical apparatus of the start system and comprising at least one guiding element,
a primary mounting element capable of occupying a retracted position and a deployed position in which the primary mounting element forms a primary housing with the support in which is intended to be inserted a first portion of the first securing rail by defining a first relative securing position (P 1 ) of the first securing rail with respect to the first electrical apparatus, the primary mounting element being arranged to be guided between the retracted position and the deployed position by said at least one guiding element, and
a return element arranged for returning the primary mounting element towards the deployed position,

the first insulating casing comprising a first pressing area intended to collaborate with a second portion of the first securing rail when the first securing rail is disposed according to the first relative securing position (P 1 ) with respect to the first electrical apparatus,
the first securing rail extending along a second extension direction (D 2 ) transversal to the first extension direction (D 1 ) when the first securing rail is disposed in the first relative securing position (P 1 ) of the first securing rail with respect to the first electrical apparatus, and
the second securing rail being in a first relative securing position (P 1 ′) of the second securing rail with respect to the second electrical apparatus when the second electrical apparatus is mounted with the first electrical apparatus and the first securing rail is in the first relative securing position (P 1 ), in which the second securing rail is extending along the second extension direction (D 2 ) and is shifted in the first extension direction (D 1 ) with respect to the first securing rail.

2. The start system according to claim 1 , wherein the support comprises a locking element comprising a pressing portion intended to collaborate with the first electrical apparatus.

3. The start system according to claim 2 , wherein the support comprises an elastic element comprising a bearing portion intended to collaborate with the first electrical apparatus.

4. The start system according to claim 3 , wherein the elastic element comprises a planar portion and an opening.

5. The start system according to claim 3 , wherein the first insulating casing comprises:
a retaining housing comprising an inserting portion for inserting the locking element of the mounting device and a pressing part against which the locking element of the mounting device is in abutment, and
a maintaining element arranged to collaborate with the bearing portion of the elastic element of the mounting device.

6. The start system according to claim 1 , wherein the primary mounting element comprises a gripping portion.

7. The start system according to claim 1 , wherein the first electrical apparatus further comprises a first individual securing device comprising:
a first individual mounting element being stationary and forming with the first insulating casing, a first housing in which is intended to be inserted the first portion of the first securing rail by defining a second relative securing position (P 2 ) of said first securing rail with respect to the first electrical apparatus, and
a second individual mounting element moveable between a retracted position and a deployed position, and forming with the first insulating casing, a second housing when the second individual mounting element occupies its deployed position, in which is intended to be inserted the second portion of the first securing rail when the first securing rail is disposed according to the second relative securing position (P 2 ) of said first securing rail with respect to the first electrical apparatus.

8. The start system according to claim 7 , wherein the first individual securing device comprises a first pressing housing defined between the first individual mounting element and the second individual mounting element, forming the first pressing area.

9. The start system according to claim 7 , wherein the second electrical apparatus comprises a second individual securing device comprising:
a third individual mounting element moveable between a retracted position and a deployed position, and forming with a second insulating casing a third housing when the third individual mounting element occupies its deployed position, in which is intended to be inserted a first portion of the second securing rail in a second relative securing position (P 2 ′) of said second securing rail with respect to the second electrical apparatus, and
a fourth individual mounting element forming with the second insulating casing a fourth housing in which is intended to be inserted a second portion of the second securing rail disposed in the second relative securing position (P 2 ′) of said second securing rail with respect to the second electrical apparatus.

10. The start system according to claim 1 , wherein the second extension direction (D 2 ) is oriented according to an angle between 60° and 120° with respect to the first extension direction (D 1 ).

11. The start system according to claim 1 , wherein the second electrical apparatus comprises a second insulating casing and, in complement with the primary mounting element of the first electrical apparatus when the second electrical apparatus is mounted with the first electrical apparatus and the first securing rail is in the first relative securing position (P 1 ), a secondary mounting element being stationary and forming with the second insulating casing a secondary housing in complement with the primary housing formed by the primary mounting element and the support,
the secondary housing being intended to receive a first portion of the second securing rail in the first relative securing position (P 1 ′) of the second securing rail with respect to the second electrical apparatus, and
