Description

The invention relates to a fixing arrangement for a vehicle having at least two conductor wires and a summation screen.

Cables in the vehicle are often fixed at a predetermined distance from a connector and / or decoupled, for example, a strain relief. Especially with multi-pin lines can be damaged by this fixation example, a sum screen that shields the individual wires of the line electromagnetically.

The object on which the invention is based is to provide a fixing arrangement for a vehicle, by means of which a reliable fixing of at least two cable cores is made possible.

The object is solved by the features of the independent claim. Advantageous embodiments are characterized in the subclaims.

The invention is characterized by a fixing arrangement for a vehicle, which has at least two conductor wires. The fixing arrangement has a summation screen which electromagnetically shields the line conductors. The fixing arrangement has a fixing unit with a plurality of recesses for performing the individual conductor wires. The fixing unit is arranged within the summation screen. The fixing arrangement has a clamping unit, which is arranged outside the summation screen and which is designed to exert a clamping force on the summation screen and the fixing unit on the line wires.

Such conductor wires, which are shielded with a sum screen, are used, for example, for Motoransteuerleitungen. For this example, three wires are used.

The sum screen is for example a braided hose, for example made of a metal.

The fixing unit has, for example, a plastic or a rubber. It is slightly elastic, for example.

The sum screen surrounds the leads to shield them electromagnetically. Without the fixation unit, the summation screen can be easily damaged if the conductor wires are fixed from outside the summation screen. The fixing unit, which is arranged within the summation screen, contributes to a clamping force exerted externally on the summit screen being transmitted to the line conductors such that the summit screen is not damaged. In particular, such a contribution is made that the clamping force is transmitted evenly distributed over the summation screen. Thus, a simple and reliable fixation of the wires from the outside is possible. By fixing from the outside, the line wires can be fixed at any point of the line wires, for example, to decouple the wires or to realize a strain relief.

In this context, the outside is in relation to a cross-section perpendicular to the respective extension direction of the conductor cores in the region of the fixing unit in relation to the summation screen.

According to an advantageous embodiment, the recesses of the fixing unit are circular and the diameter of the recesses corresponds approximately to the diameter of the conductor wires.

If the diameter of the recesses corresponds approximately to the diameter of the conductor leads, or if the diameter of the recesses corresponds in particular to the diameter of the conductor leads, then the clamping force can be exerted very well on the conductor leads.

According to a further advantageous embodiment, the outer shape of the fixing unit and the shape of the sum screen are adapted to each other.

The outer shape of the fixing unit and the shape of the summation screen are adapted to each other, for example, so that the summation screen rests on the fixing unit or on an element between the fixing unit and the summation screen. As a result, it may be ensured, if appropriate, that the total screen is not damaged by the fixation since it does not deform or only slightly deforms due to the fixation. At the same time this can be achieved by a good force on the wires.

According to a further advantageous embodiment, the fixing unit is elliptical and the fixing unit is formed so that the summation screen rests on the fixing unit.

For example, with an odd number of wires, such as three-pole Motoransteuerleitungen, but also with a straight number of wire cores can be exercised by the elliptical shape very well, the clamping force on the wires. By the sum screen is applied to the fixing unit, may contribute to the fact that the sum screen may not is damaged by the fixation, since it is not or only slightly deformed by the fixation.

According to a further advantageous embodiment, the fixing unit is formed in two parts.

As a result, for example, a very simple assembly with very good clamping force is possible.

According to a further advantageous embodiment, the two parts of the fixing unit each have parts of all recesses for performing the individual wires.

As a result, the respective cable cores can be easily performed by the fixing unit. For example, the two parts of the fixing unit each have semicircular recesses for performing the individual conductor wires.

According to a further advantageous embodiment, the clamping unit additionally has a fastening element by means of which the clamping unit can be fastened to a fastening device.

For example, the fastener has a plurality of recesses, such as holes. Through these recesses, the fastening element, for example by means of screwing, can be fixed to the fastening device. The fastening device is for example a part of the body of the vehicle.

According to a further advantageous embodiment, the fixing arrangement additionally has a protective tube, which is designed to seal the conductor wires and the sum screen, in particular against the ingress of liquids. The clamping unit is arranged outside the protective tube.

Outside is in this context with respect to a cross-section perpendicular to the respective extension direction of the wires in the region of the fixing unit with respect to the protective tube.

As a result, a fixation of the wires in a protective tube, such as a corrugated pipe is possible.

According to a further advantageous embodiment, the fixing arrangement additionally has a plug to which the line wires are connected and to which the summation screen is attached.

As a result, a fixation of the wires at a predetermined distance from the plug is possible. This is particularly advantageous in applications in which the distance from the plug to the fixation of the conductor wires, for example, for decoupling, is fixed.

According to a further advantageous embodiment, the fixing arrangement additionally has a connector grommet, which is fastened to the plug and which encloses the summation screen. The clamping unit is arranged outside the connector grommet.

Outside is in this context with respect to a cross-section perpendicular to the respective extension direction of the wires in the region of the fixing unit with respect to the connector grommet.

The Steckertülle has, for example, a plastic. It is intended, for example, to seal the cable cores and the total screen, for example against the ingress of liquids.

As a result, the summation screen and the cable cores can be protected from liquids by the connector grommet, for example. Furthermore, this is a fixation of the wires in the area of the connector grommet, especially in the vicinity of the plug possible. Furthermore, it can be helped by the fixing unit that the connector grommet is not damaged by the fixation of the wires.
