Description

Technical Field

[0001] The invention relates to a vibration-damping element which is arranged on an outer sheath of a cable and in which at least one electrical conductor is arranged which is preferably connected to a contact counterpart of a plug-in connector. Background Art

[0002] In accordance with Figure 7 and 8 In the existing solutions, the sealing sleeve is pushed onto the wire. The wire (cable) comprises at least one electrical conductor 1, which is arranged in an outer sheath 2. A contact counterpart 3 is arranged at one end of the electrical conductor 1. Figure 7 This arrangement is, for example, a component of a plug-in connector for a plug connection. The sealing sleeve is a component made of two components: a soft component formed by silicon 4 and a hard component formed by plastic 5. The soft component is arranged coaxially within the hard component and the structural unit consisting of the two components is pushed onto the outer sheath 2. This component can also be used for a plurality of conductor cross sections, but the material consumption (silicon) is correspondingly higher in the case of fewer cross sections. Summary of the invention

[0003] The object of the present invention is to improve the above-mentioned arrangement, in particular by preventing / minimizing vibrations of the contacts in the installed / plugged state and reducing the material consumption.

[0004] This object is achieved by the features of claim 1 .

[0005] According to the invention, a damping element made of only one component is used, which is arranged on the outer sheath of the cable, in which at least one electrical conductor is arranged, which is preferably connected to the contact partner of the plug connector, and which has at least one recess in its wall and preferably extends parallel to its longitudinal axis, so that the at least one recess ensures that the compression force is not too high at the maximum tolerance, but the damping element is still compressed at the minimum tolerance. The advantage of using only one component is that a second component is omitted and the material consumption is thus reduced. In addition, the number of components to be installed is reduced.

[0006] Thus, a damping element made of only one component is used. If the desired damping properties and / or mounting forces cannot be achieved immediately, these parameters can be changed very simply by adjusting the hole geometry (number and shape of the recesses). Thus, no complicated adjustments / changes to the associated and adjacent components are necessary.

[0007] The perforations also ensure that the contact pressure is not too high at the maximum tolerances, but that the damping element is still pressed at the minimum tolerances. When used with multiple conductor cross sections in the same housing (e.g., of a plug connector), not only are the properties controlled, but a considerable amount of material is also saved accordingly.

[0008] The damping element consists of only one component (only one material). This saves process steps (preparing and processing two elements made of different materials) and material. In addition, the number of components is reduced and the installation effort is reduced.

[0009] According to one embodiment of the invention, the damping element has at least one recess in its wall and preferably extending parallel to its longitudinal axis. The recess(es) arranged in the wall are arranged symmetrically or asymmetrically. The recess can be completely surrounded by the material of the wall (in the form of a bubble) or can also be open in some areas, for example (see, for example, the elongated cylindrical recess of the embodiment in the drawing). The cross section is, for example, circular, oval, elongated, square, rectangular or the like.

[0010] If the desired damping properties and / or mounting forces cannot be achieved immediately, these parameters can be changed very simply by adjusting the geometry of the recesses (the so-called hole geometry, i.e. the number and shape). Thus, no complex adjustments / changes to the relevant and adjacent components are necessary.

[0011] The damping element is arranged on an outer sheath of the cable, within which at least one electrical conductor is arranged which is preferably connected to a contact partner of a plug connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Next, we will again use Figures 1 to 6 The damping element according to the invention is described in detail and further explained. DETAILED DESCRIPTION

[0013] Figure 1 The damping element 6 according to the invention is shown, which has a wall around a through-opening 7 for the conductor outer sheath 2. At least one recess (perforation), preferably a plurality of recesses, is provided in the wall.

[0014] exist Figure 2 It is shown that the damping element 6 is pushed onto the outer jacket 2 .

[0015] exist Figure 3 It is also shown in Figure 2 The same damping element 6 is pushed onto the outer sheath 2. However, it can be seen here that according to Figure 2 The outer sheath 2 has a ratio according to Figure 3The decisive advantage of the damping element 6 according to the invention can therefore also be seen directly: by expanding (lengthening) the recess in the damping element 6, the damping element 6 can be adapted to the different diameters of the outer sheaths 2 of different conductors via its through opening 7.

[0016] This adaptation is variable and can be adjusted by the number and / or cross-section of the recesses, for example Figure 4 It can be seen there that the damping element 6 (in Figure 4 The wall surrounding the through-opening 7 has a larger Figure 4 The damping element 6 shown on the right has a significantly greater number of recesses 8. By varying the number of recesses 6 and / or their geometry, the diameter range of the through-opening 7 can be varied to precisely defined values. Thus, for example, depending on Figure 4 The damping element 6 shown on the left can be compared to Figure 4 The damping element 6 shown on the right is expanded to a much greater extent (so that the diameter of the through-opening 7 can also be much larger). This can optionally also be combined with different materials.

[0017] It should be pointed out here that Figures 1 to 4 The damping element 6 shown in FIG. 1 has recesses 8 in the form of recesses 8 which are present in the wall of the damping element 6 in an elongated, radially extending manner. It is of course conceivable to vary the shape of the cross section and the position of the respective recess 8 in the wall of the damping element 6. Thus, for example, recesses 8 with a circular cross section and recesses 8 with an elongated cross section, but oriented transversely to the radial extension (thus with respect to Figures 1 to 4 The notch 8 in FIG. 8 is rotated 90°. It should be noted that this Figure 5 Shown in.

[0018] In order to fix the position of the vibration-damping element 6 on the outer sheath 2, it is conceivable to provide an element protruding from the through-opening 7 in the direction of the central longitudinal axis of the vibration-damping element 6, such as at least one circumferential web (oriented transversely or parallel to the longitudinal axis of the vibration-damping element 6), one or more protrusions or the like.

[0019] In addition or as an alternative thereto, it is provided that the damping element 6 has at least one circumferential web 9 and / or at least one circumferential recess 10 on its circumferential surface. Figure 5 and 6 Shown in.

[0020] Here, it can also be seen in another embodiment of the invention that the at least one circumferential web 9 is arranged set back relative to the end (end face) of the damping element 6 .

[0021] In accordance with Figure 5 and 6In the two exemplary embodiments of the embodiment ...

[0022] Reference Figure 5 It can also be seen that the recess 7 in the damping element 6 is arranged in the wall transversely to the radial extension. Figure 6 It can be seen that a recess 8 with a circular cross section is provided in the wall of the damping element 6. Figure 5 and 6 The damping element 6 shown has through-openings 7 of different sizes, so that these through-openings can be pushed onto the outer sheath of conductors with different diameter ranges. This means, for example, that Figure 5 The inner diameter of the through opening 7 of the damping element 6 is 15 mm. By expanding, the damping element 6 can thus be pushed onto a conductor with an outer sheath 2 diameter in the range between (slightly larger than) 15 mm and 20 mm. If, on the other hand, a conductor with an outer sheath 2 diameter in the range between (slightly larger than) 5 mm and 10 mm is to be used, then the damping element 6 according to Figure 6 A damping element 6 in which the inner diameter of the through-opening is 5 mm. The above dimensions (in millimeters) are purely exemplary and can be easily changed depending on the application.

[0023] In a special design, Figure 5 and 6 The circumferential outer geometry of the damping element 6 shown in FIG. 1 is also present internally in the region of the through-opening 7 , the number of inner and outer webs / recesses being able to be identical or different.

[0024] Therefore, to summarize again, the present invention relates to a vibration-damping element, which is made of only one component (only one material), the vibration-damping element is arranged on the outer sheath of a cable, at least one electrical conductor is arranged in the outer sheath, which is preferably connected to the contact counterpart of the plug connector, the vibration-damping element preferably has at least one recess in its wall and preferably extending parallel to its longitudinal axis, the recess arranged in the wall is arranged symmetrically or asymmetrically and is completely surrounded by the material of the wall (in the form of a bubble) or is open in partial areas, for example, so that the at least one recess (perforation) ensures that the extrusion pressure is not too high at maximum tolerances, but the vibration-damping element is still squeezed at minimum tolerances.
