Definitions

• the present invention relates to an electrical connection and fixing system of at least one electrical conductor in the form of a plate on a support piece.
• the invention relates to such systems in which the support part is provided with a stud adapted to engage in a corresponding hole of the conductor and to cooperate with a clamping nut of the conductor on the support part. .
• connection systems are commonly used, for example, in plate or busbar systems for connecting electrical conductors.
• connection systems have a certain number of drawbacks, in particular during the positioning and tightening of the conductor against the support part, in places which are difficult to access.
• connection systems are generally placed in the bottoms of electrical supply cabinets or baskets and are difficult to access for assembly operators. It can then happen that this operator lets escape one or the other of the parts entering into the constitution of these systems and that this one is difficult or even impossible to recover.
• the object of the invention is therefore to solve these problems.
• the subject of the invention is a system for electrical connection and fixing of at least one electrical conductor in the form of a plate on a support piece provided with a stud adapted to engage in a corresponding hole in the conductor. and to cooperate with a nut for clamping the conductor on the support piece, characterized in that an annular spacer made of electrically conductive material is associated with the conductor on the side of this conductor directed towards the support piece, and in that the nut is placed on the opposite side of the conductor, and is associated with the spacer by attachment means allowing the rotation of the nut relative to the spacer and a determined stroke of axial displacement of the nut relative to this spacer, between a mounting position remote from the conductor and a clamping position in abutment against the latter, to facilitate installation and then clamping of the conductor against the support piece.
• the conductor hole has a generally oblong shape to facilitate its centering on the stud;
• the means for attaching the nut to the spacer are in the form of a tubular sleeve of the nut adapted to extend into the hole of the conductor and the free end of which is provided with stop means adapted to cooperate with complementary stop means of the spacer;
• the stop means of the end of the sleeve comprise at least one projecting part and that the complementary stop means of the spacer comprise at least one corresponding flange;
• the means for attaching the nut to the spacer include hook-shaped tabs adapted to engage in the corresponding hole of the conductor and to cooperate with complementary stop means of this spacer;
• the spacer has on its side directed towards the driver means in the form of a receiving slide thereof, allowing a determined travel of transverse movement of the spacer and the nut relative to the driver to facilitate its centering on the stud;
• the support piece comprises at the stud, a reinforcing piece;
• the support part is formed by another conductor
• the support part is formed by an electrical component
• the support part is formed by an electrical connection plate.
• - Fig.1 shows a perspective view of an electrical connection system according to the invention in the mounting position
• - Fig.2 shows a sectional view of such a system
• FIG.3 shows a perspective view of such a system in the clamping position
• FIG.4 and 5 show perspective views respectively of an annular spacer and a nut, forming part of such a system
• - Fig.6 shows a sectional view of an example of application of such a connection system.
• FIGS. 1 to 5 show in fact an electrical connection and fixing system for at least one electrical conductor in the form of a plate, designated by the general reference 1, on a support piece designated by the general reference 2
• This support piece 2 comprises a stud designated by the general reference 3, adapted to engage in a corresponding hole 4 of the conductor 1 and to cooperate with a tightening nut 5 of the conductor on the support piece 2.
• this support piece 2 can be formed by another conductor, an electrical component, an electrical connection plate or bar, etc.
• the support part 2 is formed by another conductor, designated by the general reference 2a in these figures, provided at the stud 3, with a reinforcing part designated by the reference general 2b.
• connection system comprises an annular spacer made of electrically conductive material, and which is designated by the general reference 6 in these figures.
• This annular spacer made of electrically conductive material 6 is associated with conductor 1, on the side of this conductor directed towards the support part 2.
• the nut 5 is placed on the opposite side of the conductor 1 and is associated with this spacer 6 by attachment means allowing the rotation of this nut relative to this spacer and a determined stroke of axial displacement of this nut relative to this spacer between a mounting position remote from the conductor, as illustrated in FIGS. 1 and 2 and a clamping position in abutment against the latter as illustrated in FIG. 3. This makes it easier to set up then clamping the conductor against the support piece, as will be described in more detail below.
• These means for attaching the nut to the spacer can of course have different shapes.
• these means for attaching the nut to the spacer may be in the form of a tubular sleeve 5a of the nut, the free end of which is provided with stop means, for example 5b suitable for cooperate with complementary stop means of the spacer formed for example by a flange 6a thereof.
• the abutment means of the end of the sleeve can include at least one projecting part adapted to cooperate with the corresponding flange of the spacer.
• these means for attaching the nut to the spacer can for example include lugs in the form of hooks adapted to engage in the corresponding hole of the conductor and to cooperate with complementary stop means of this spacer, formed for example by the flange.
• the spacer also comprises, on its side directed towards the conductor, means in the form of a reception slide for the latter, as designated for example by the general reference 6b.
• the hole 4 of the conductor has a generally oblong shape to facilitate its centering on the stud.
• the means in the form of a slide 6b of the spacer and this generally oblong shape of the hole 4 of the conductor allow a determined travel of transverse movement of the spacer 6 and therefore of the nut 5 attached on the latter, relative to the conductor 1, to facilitate its centering on the stud 3 of the support piece.
• This sub-assembly being able to move slightly with respect to the conductor, this allows a possible misalignment between the stud of the support piece and the rest of the system to be made up.
