Abstract

A plug connecting unit for connecting a cable circuit in a cable circuit housing with a sensor module in a sensor module housing, comprising a wireless interface for energy- and/or data transmission between the cable circuit and the sensor module. A first section of the wireless interface is arranged in the cable circuit and a second section of the wireless interface is arranged in the sensor module. The wireless interface is surrounded by a magnetic shielding and the magnetic shielding is arranged in the cable circuit housing and/or in the sensor module housing.

Claims

1. A plug connecting unit for connecting a cable circuit in a cable circuit housing with a sensor module in a sensor module housing, comprising:

a wireless interface for energy and/or data transmission between the cable circuit and the sensor module, wherein;

a first section of said wireless interface lies in the cable circuit, and a second section of said wireless interface lies in the sensor module;

said wireless interface is surrounded by a magnetic shielding of a conductive material, the magnetic shielding being tubularly embodied and including a longitudinal slit; and

said magnetic shielding is arranged in the cable circuit housing and/or in the sensor module housing.

2. The plug connecting unit as claimed in claim 1, wherein:

said wireless interface is embodied as an inductive or capacitive interface.

3. The plug connecting unit as claimed in claim 1, wherein:

said magnetic shielding is composed of a film or a sheet, which is arranged in the interior of the cable circuit housing and/or sensor module housing.

4. The plug connecting unit as claimed in claim 1, wherein:

said magnetic shielding is placed in a cable circuit housing of plastic and/or in a sensor module housing of plastic.

5. The plug connecting unit as claimed in claim 4, wherein:

said cable circuit housing and/or the sensor module housing are produced completely or partially of a plastic bonded ferrite.

6. The plug connecting unit as claimed in claim 5, wherein:

the magnetic shielding is embedded in the cable circuit housing and/or the sensor module housing via the plastic bonded ferrite material.

7. The plug connecting unit as claimed in claim 4, wherein:

said magnetic shielding is embodied in at least one region of the cable circuit housing, which surrounds said first section of said wireless interface, and/or at least in a region of a sensor module housing, which surrounds said second section of said wireless interface.

8. The plug connecting unit as claimed in claim 1, wherein:

said magnetic shielding is composed of a material with a relative permeability >

1.

9. The plug connecting unit as claimed in claim 8, wherein:

said magnetic shielding is ferromagnetic.

10. The plug connecting unit as claimed in claim 1, wherein:

the cable circuit housing and the sensor module housing are tubularly embodied and have a diameter of about 12 mm.

11. The plug connecting unit as claimed in claim 1, wherein:

the magnetic shielding is incorporated within the cable circuit housing and/or the sensor module housing in a material of the cable circuit housing and/or the sensor module housing.
