Abstract

The device comprises a small base 2 intended to be fixed to a support structure 23 and to a retaining clip 3. This retaining clip 3 comprises a hub articulated in rotation on the small base and from which two curved tongues extend transversely and that can be elastically separated, can hold one or more electric cables 27 of the installation. The retaining clip 3 can adopt with respect to the small base 2 a preestablished position so as to be unfolded in the working position and folded in the rest position, which represents the minimum bulk.

Description

DEVICE FOR RETAINING CABLES IN A

ELECTRICAL INSTALLATION

  The present invention relates to a cable retention device in an electrical installation and in particular the retention of electrical cables connected to an electrical generator mounted on board a motor vehicle. The retaining device according to the invention is characterized in that it comprises a small base intended to be fixed on a support structure and a retaining clamp comprising a hub articulated in rotation on said small base and from which extend transversely two bent tabs which can be separated elastically, capable of

  maintain one or more cables of the installation.

  This retaining clip can take, relative to the small base, a predetermined position, unfolded for work and folded back in the rest position, which has a

minimum space requirement.

  Additional features and benefits

  of the invention will appear from the detailed description

  which follows, with reference to the appended drawing tables, provided by way of example but not limiting, or: - FIG. 1 is a perspective view of a device according to the invention; - fig. 2 is a section along line II-II of FIG. 1 of a device according to the invention; - fig. 3 is an exploded perspective view of a device according to the invention; - fig. 4 is a side view of an alternator provided with a device according to the invention, and - FIG. 5 & a front view of the alternator

illustrated in fig. 4.

  A device 1 according to the invention (FIGS. 1 to 3) comprises a small base 2 intended to be fixed to a support structure and to a retaining clamp 3 articulated in rotation on the small base and which can take, with respect to this- ci, a preset position, unfolded in the working position (in solid lines in fig. 2) and folded back in the rest position (in thin dashed lines in fig. 2), which has a

minimum space requirement.

  This retaining clamp 3 has a hub 4 provided at its end with aligned pins 5 and protrusions 6 and from which cross two curved tongues 7 which can be spaced apart elastically, capable of holding one or more electric cables. The hub 4 also has a recess 14 orthogonal to the axis defined by the pins 5 and, on its lateral surface, next to the recess 14, a pair of

teeth 15.

  The small base 2 has two appendages facing each other 8 which can be separated in which are formed longitudinal grooves 9 having guide surfaces 10 and in which open

holes 11 aligned.

  On the small base (Figure 2) is also formed a cavity 12 with a stop surface 13 and a hole 16 for the passage of a fixing member to the structure

  support (not shown in the figure).

  - The projections 6 of the retaining clip 3 have shapes complementary to those of the grooves 9 of the appendices 8 in which they must be inserted

  when the device 1 is in the working position.

  The pins 5 of the hub 4 must, however, be inserted into the holes 11 of the appendix 8, allowing the rotation of the retaining clamp 3 relative to the small base 2. In the mounting of the device 1, their insertion is facilitated by the engagement surfaces 10 of the grooves 9 and by the fact that the appendages 8

can be dismissed.

  During the rotation of the retaining clamp 3 relative to the small base 2 from a folded rest position, indicated in thin phantom in Figure 2, the pair of teeth 15 of the hub 4 acts on the surface stop 13 of the cavity 12 of the small base 2, blocking the movement of the retaining clamp 3 and defining the working position of the latter. The locking of the retaining clamp 3 in this position is also obtained by the snap-fastening of the projections 6

  in the grooves 9 of the appendices 8.

  The rotation bringing the retaining clip 3 from the rest position to that of work and vice versa is made possible by the spacing of the appendages 8 as a result of the action of the projections 6 of the hub 4 which emerge from the grooves 9, and by the compression of

the recess 14 of the hub 4.

  The small base 2 and the retaining clip 3 are made of plastic, preferably acetal resin. To avoid damage to this material during the attachment of the device to a support structure, a cleavage metal ring 17 of reinforcement placed in the hole 16 makes it possible to apply an adequate tightening torque to a screw fixing member, not illustrated. in fig. 1 to 3, passing through the

hole 16.

  In fig. 4 and 5, we see a device 1 according to the invention mounted on an alternator 21 of a motor vehicle. The small base 2 is mounted on the body 23 of the alternator by means of a bolt 24. The retaining clamp 3 retains a corrugated tube 26 through which passes a bundle of electrical cables 27 which are thus well maintained in the adjacent position by report to the alternator. For the storage of the alternator 21, it is however possible to fold the retaining clip 3 in the rest position, indicated by a thin dashed line in FIG. 4, which thus avoids possible damage to this part due to impacts against

other elements.

  This embodiment therefore clearly shows the usefulness of the device according to the invention, which can adopt the most advantageous configuration, that

  whether in working or resting condition.

  It goes without saying that the effects of the present invention extend to models which aim to achieve the same objectives thanks to the same innovative concepts.
