DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention is based on a cable retainer. A cable retainer is already known (German Patent Disclosure DE 24 40 201 A1) that is integrated into the casing of a cooling fan of an internal combustion engine, but there is a risk that the cable retainer will break off when the cable is installed or removed, since for reasons of strength a relatively inelastic plastic is used for the casing.
ADVANTAGES OF THE INVENTION
The cable retainer according to the invention, has the advantage over the prior art of being simple in construction, allowing easy installation and removal of the cable with little risk of breakage of the cable retainer. To install or remove the cable, the retaining tongue need merely be bent slightly, while in the installed state of the cable bending forces no longer act on the retaining tongue; only pressure forces act on the end face of the free end, so that a secure hold of the cable is assured even if vibrational stresses occur.
Advantageous refinements of and improvement to the cable retainer defined by the main claim are possible by means of the provisions recited hereinafter.
It is especially advantageous, for the retaining tongue provided with a bottom face oriented toward a body, a top face remote from the body and side faces, to provide a guide rail next to each side face of the retaining tongue; the guide rail has a guide face with a portion that is at least partly inclined relative to the top face and that at least in the direction toward the free end of the retaining tongue extends with a less spacing from the body than the bottom face of the retaining tongue. During installation and removal of the cable, the guide faces of the guide rail prevent the retaining tongue from being bent past its limit of elasticity and breaking.
It is also advantageous to make the cable retainer of plastic and to embody it as an integral part of the body.
BRIEF DESCRIPTION OF THE DRAWING
One exemplary embodiment of the invention is shown in simplified form in the drawing and described in further detail in the ensuing description.
FIG. 1 shows a three-dimensional view of the cable retainer of the invention;
FIG. 2 is a section through the cable retainer of FIG. 1 during the installation of a cable; and
FIG. 3 is a section through the cable retainer of FIG. 1 with a cable installed.
DESCRIPTION OF THE EXEMPLARY EMBODIMENT
In FIGS. 1-3, a cable retainer 1 is shown which either is embodied as an independent component or is an integral part of a body 2, which is formed for instance by the casing of a cooling fan for internal combustion engines, as shown in DE 24 40 201 A1, which is hereby expressly incorporated by reference in this respect. If the cable retainer 1 and the body 2 are separate components, then they are joined together in a manner not shown, such as by adhesive bonding, soldering, welding, or by screw fastening. The cable retainer 1 and the body 2 may be of different materials. If the cable retainer 1 is an integral component of the body 2, then plastic is used as the material for it.
The cable retainer 1 has a retaining element 5, which has a rectangular cross section, for instance, and which, beginning at the body 2, has a vertical flat wall 6 extending away from the body and adjoining the flat wall (6) a curved wall 7, which extends circularly for instance and describes at least a quarter-circle. In the exemplary embodiment shown, the curved wall 7 extends over approximately 120.degree. and ends at a free wall end 10, which in the exemplary embodiment shown is inclined toward the body 2. An inner wall 11 of the retaining element 5 has a flat portion 12 in the region of the flat wall 6, and a curved portion 15 in the vicinity of the curved wall 7.
The cable retainer 1 also has a spring-elastic retaining tongue 16, whose free end 17 is aimed with its end face 20 toward the retaining element 5. The retaining tongue 16 has a rectangular cross section and extends along a longitudinal axis 21 from a fixed tongue end 22 to the free tongue end 17 with a top face 25 remote from t
