Description

1 2557384

  The present invention relates to the field of food

  electrical distribution of movable mechanisms such as overhead cranes, monorails, hoists, small work tools of the drill type, screw machine, or the like, and other devices movable, by means of a sheath, and has for object a feeding device

  electric for such mechanisms.

  Feeders of this type currently existing, are generally in the form of a conductor on which rubbing a current sensor, whose guidance is provided by the insulating jacket of the driver or by a device outside the device of 'food. However, these known devices require ancillary guiding devices and ensuring the maintenance of a good electrical contact thereby increasing the risks of

  malfunction or unreliability.

  The present invention aims to overcome these disadvantages.

  Its purpose is, in fact, to provide a food

  electrical connection for movable mechanisms, characterized in that it is constituted by a box-shaped conductor provided with an insulating envelope, and by a current taker

  in the form of a guide carriage that follows the contours of

  drivers and provided with a current-picking brush, which is pushed into contact with the driver by means of

  pressure springs, and which is connected to the food machine

  Corresponding menter by a flexible connecting cable.

  The invention will be better understood thanks to the description

  below, which relates to a pre-

  1, is given by way of non-limiting example, and explained with reference to the appended schematic drawing, in which: FIG. 1 is a side elevational view in longitudinal section of a device according to the invention, and

  Figure 2 is a sectional view along A-A of Figure 1.

  According to the invention, and as shown more particularly, by way of example, FIGS. 1 and 2 of the appended drawing, the power supply device for mobile mechanisms consists of a conductor

  box shape 1, which is provided with an insulating envelope

  2, and by a current taker in the form of a trolley

guide 3.

  The latter has a contour conforming to the inner contours of the conductor 1, and is provided with a broom 4 of

  socket, which is pushed into contact with the

  1 by means of pressure springs 5, and which is connected to the corresponding feeding machine by a cable of

flexible connection 6.

  On at least one of its surfaces in contact with the conductor 1, the guide carriage 3 is advantageously provided with a coating layer 7 made of an anti-friction material, preferably on its lateral lower faces supporting the largest load and the Thus, a perfect guiding of the guide carriage 3 in the conductor 1 is ensured in a perfect manner, while avoiding

  undesirable wear of the surfaces in contact.

  The box-shaped conductor 1 is a supply sheath whose continuity solutions have the characteristics of FR-A-2 420 864, especially for

  the taking into account of the phenomena of dilation.

  Suspensions for fixing conductors

  and their casing can be mounted by means of

  in the conductor 1 according to a modular arrangement

constant spacing.

  Thanks to the invention, it is possible to ensure the guiding of a current sensor, such as the guide carriage 3, entirely by the conductor 1, without any additional organ,

  forces necessary to maintain good electrical contact

  that being inside the driver assembly 1 - carriage-

  3. Actually, the force of application of the current-picking brush 4 against the corresponding face of the conductor 1, supplied by the springs 5, generates a reaction force

  tending to apply the guide surfaces of the carriage

  3 against the corresponding surfaces of said conductor 1. Finally, the conductor 1 itself performs its function of carrying current and mechanical support, the envelope

  2 only providing an electrical isolation function.

  Of course, the invention is not limited to

  embodiment described and shown in the accompanying drawing.

  Modifications are possible, particularly from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without departing from the

  field of protection of the invention.
