Definitions
- a cable generally has a cable shield surrounding the entirety of the lines carried along.
- the cable shield is, for example, in the form of an electrically conductive metal braid jacket or a metal foil winding.
- the cable shield which is often also used as a return conductor, must be electrically contacted with the connector housing.
- the electrical connection of the cable shield takes place in the connector housing and should take place as evenly as possible over the circumference of the cable.
- this is particularly necessary for the uninterrupted electromagnetic shielding of the lines inside the cable.
- a corresponding contacting device, the so-called “cable shielding support”, thus represents a subcomponent of the generally ring-shaped connector housing.
- a contacting device for the metal braid jacket of shielded cables which can be made electrically conductive with a connector housing.
- the contact element of the contacting device is formed by a helical spring pressed against the metal braid jacket and accommodated in an annular housing with a C-shaped cross section. Furthermore, a sleeve-shaped clamping part, which can be locked with the helical spring, can be inserted into the metal braid jacket to clamp it.
- a disadvantage of the device listed above is that the contacting device is in three parts.
- the helical spring must be in addition to the assembly steps which take place in a shield-contacting manner are first inserted into the ring-shaped housing with a C-shaped cross section in an extra assembly step.
- both the annular coil spring and the annular housing are characterized by relatively complex manufacturing processes and increased production costs due to the C-shaped cross section.
- the invention is based on the object of specifying a device for contacting the cable shield of a cable, in particular in a connector housing, which can be manufactured with less effort and is easier to handle.
- the object is achieved by the device for electrical contacting of a cable shield specified in claim 1.
- the contacting device has only two parts. This is particularly beneficial for quick and easy-to-use assembly.
- the cable shield for example in the form of a metal braid jacket, can be contacted with a plug housing by means of a clamping ring and a retaining disk which can be snapped onto it.
- Another advantage is the low production costs of the two-part contacting device.
- IG 1 shows, by way of example, a sectional illustration of a ring-shaped connector housing with the contacting device according to the invention with a mounted cable
- FIG. 2 shows an example of a sectional view of a cable and the contacting device according to the invention
- FIG 3 shows an example of a plan view of an embodiment of the clamping sleeve of the contacting device according to the invention.
- FIG. 1 shows an example of a sectional illustration of an annular plug housing 13, into which a cable 9 is guided.
- the cable has cable strands 92 which are electrically conductively connected to the plug contacts 14 of the plug housing 13.
- the cable 9 also has a cable shield 91 surrounding the cable strands 92.
- the cable shield 91 is, for example, an electrically conductive metal braid jacket or a metal foil winding, which serves for the electromagnetic shielding of the cable strands 92. to
- the cable shield 91 is electrically conductively connected to the connector housing 13 as evenly as possible over the circumference of the cable.
- the two-part contacting device according to the invention which has a sleeve-shaped clamping sleeve 1 and a holding disk 10.
- the clamping sleeve 1 and the holding disk 10 are additionally mechanically and electrically connected to the connector housing 13 by screwing or locking (not shown).
- FIG. 2 a sectional view of the cable 9 and the contacting device according to the invention is shown as an example for further explanation.
- This has an electrically conductive, annular clamping sleeve 1, the jacket 34 of which is provided at one end 3 with at least one axial slot 41.
- the axial slot 41 runs approximately par- allel to the axis of symmetry of the clamping sleeve 1.
- the contacting device according to the invention furthermore has a holding disk 10, in the passage opening 11 of which the clamping sleeve 1 can be inserted in such a way that an intermediate cable shield 91 can be electrically contacted in a resiliently jamming manner.
- the opening widths of the clamping sleeve 1 and the holding disc 10 are matched to one another in such a way that on the one hand the interposition of the cable shield 91 is possible and on the other hand there is a jamming.
- the axial slot 41 of the clamping sleeve 1 effects a spring action of its jacket 34 with respect to the passage opening 11 of the retaining disk 10 and the cable shield 91.
- the clamping sleeve 1 is above the cable shield 91 of the cable 9 can be pushed on, so that it lies in particular on the outer surface 21 of the jacket 34 of the clamping sleeve 1.
- the cable shield 91 extends from the inside through the clamping sleeve 1 to the outside.
- the holding disc 10 can be pushed over the clamping sleeve 1 and clamped with it in such a way that at the same time the cable shield 91 is electrically contacted between the holding disc 10 and the clamping sleeve 1.
- retaining washer 10 and / or clamping sleeve 1 are furthermore arranged in the plug housing 13 and connected to it in an electrically conductive manner for reasons of electromagnetic shielding (see FIG. 1).
- At least two spring segments 5 and 6 are formed by at least two axial slots 41 made in the jacket 34 of the clamping sleeve 1, whereby a spring effect of the clamping sleeve 1 in the radial direction is achieved.
- the spring segments 5 and 6 represent in particular the part of the clamping sleeve 1 which passes through the holding disk 10.
- the cable shield 91 is clamped between the outer surface 21 of the jacket 34 of the clamping sleeve 1 and the passage opening 11 of the holding disc 10 and electrically contacted.
- the spring properties of the clamping sleeve 1 are determined in particular by the number of axial slots and their individual slot depth. In the exemplary embodiment in FIG. 2, four axial slots 41, 42, 43 and 44 (the latter in FIG. 3) are shown, distributed uniformly over the circumference of the clamping sleeve 1, as a result of which the four spring segments 5 are in the clamping sleeve 1 , 6, 7 and 8 (the latter two are shown in FIG. 3).
- the clamping sleeve 1 can additionally have a flat support ring 2 at the end 4 opposite the axial slot 41, 42, 43 or 44 (the latter shown in FIG. 3).
- This advantageously serves to enlarge the outer surface 21 of the jacket 34 of the adhesive sleeve 1 and thus, owing to the larger surface area, in particular to improve the electrical contacting of the cable shield 91 between the clamping sleeve 1 and the holding disk 10.
- the support ring 2 in particular enables at least one the axial slots 41, 42, 43 and / or 44 (the latter shown in FIG. 3) to the support ring 2 with the length a. This serves as a further possibility for influencing the spring properties of the spring segments 5, 6, 7 and 8 (the latter shown in FIG. 3) which are effected by the axial slots 41, 42, 43 and / or 44.
- the clamping sleeve 1 has at the end 3 provided with axial slots 41, 42, 43 and 44 (the latter shown in FIG. 3) at least one latching lug 51, 61, 71 and / or 81 (at least outwardly curved) (the latter in FIG. 3) shown) on.
- the detent 51, 61, 71 and 81 (the latter shown in Figure 3) is used for resilient locking of the Clamping sleeve 1 with the holding disk 10 while simultaneously contacting the cable shield 91. This is advantageous in order to facilitate the assembly of the contacting device on a cable shield 91.
- the clamping sleeve 1 engages with the holding disk 10, thereby preventing the two-part contacting device from jumping apart again.
- the holding disk 10 advantageously has at least one conical inlet bevel 12 in the form of a folded phase in the passage opening 11.
- the widening 12 can then advantageously be gripped behind by the latch 51, 61, 71 or 81 (the latter shown in FIG. 3) at the end 3 of the clamping sleeve 1.
- the symmetrical design of the retaining disk 10 can be brought about by the inlet bevels 12 on both sides in the through-opening 11 shown in FIG. This is particularly advantageous during assembly, since the retaining disk 10 can be pushed onto the clamping sleeve 1 without having to observe a preferred direction. This serves in particular to reduce the assembly time.
- FIG. 3 also shows, by way of example, a top view of the clamping sleeve 1 with support ring 2 of the contacting device according to the invention already described in FIG. 2.
- the clamping sleeve 1 has four axial slots 41, 42, 43 and 44 which are evenly distributed on the jacket 34 of the clamping sleeve 1 and which are continued, for example, with the length a in the support ring 2.
- the four spring segments 5, 6, 7 and 8 are formed with the detents 51, 61, 71 and / or 81.
- the advantage of the device according to the invention is, in particular, the two-part and thus inexpensive design of the contacting device. This also benefits in particular from quick and easy-to-use assembly without the use of tools.
