Problems solved by technology

Although this is efficient in terms of production technology, it leads to limitations in the design of the measuring electrodes
A first limitation stems from the fact that the shape of the flat conductors of the known measuring electrodes is fixedly prescribed, with the result that generally more copper material is used than is technically required
A second limitation is that special plugs usually have to be provided for relatively wide flat conductors for contacting, which leads to correspondingly high material and assembly costs.

Embodiment Construction

[0026] Measuring electrodes 1 for capacitive proximity sensors 2 can be used in motor vehicles for a wide variety of fields of application. Depending on the design, it enables a sensory detection of the presence and / or movement of objects or users. The sensory detection goes back to measuring the change in capacitance of the electrode 1 relative to the substance or relative to another electrode which can easily be detected electronically. Here and preferably, the proximity sensor 2 is used to detect an operating event, ie a predetermined foot movement of the user, wherein the sensory detection of the operating event activates a motorized opening of the tailgate 3 of the motor vehicle. Another exemplary field of application is collision detection on flaps of motor vehicles.

[0027] figure 1 and figure 2 It is shown that the measuring electrode 1 has an electrical conductor structure 4 and a flat support structure 5 for receiving the conductor structure 4 . according to ...

Abstract

The disclosure relates to a measurement electrode for a capacitive proximity sensor (2) of a motor vehicle, having an electrical conductor structure (4) and having a flat carrier structure (5) for holding the conductor structure (4), where a plurality of threading openings (6) are provided in the carrier structure (5), at least one conductor (7) of the conductor structure (4) being threaded through said plurality of threading openings (6).

Description

technical field [0001] The invention relates to a measuring electrode for a capacitive proximity sensor for a motor vehicle according to the preamble of claim 1 , a capacitive proximity sensor with such a measuring electrode according to claim 12 , a machine according to claim 13 A body component of a motor vehicle to which such a proximity sensor is fastened and a method for producing such a measuring electrode according to claim 14 . Background technique [0002] The capacitive proximity sensors in question can be used in completely different fields of application. It is urgent to sensor-aided detection of operational events. The operating event to be detected can be, for example, an approach of a person to a motor vehicle, a predetermined movement of a body part, in particular a foot, of a person or the like. The sensor-assisted detection of such an operating event activates a corresponding control-technical reaction, for example a motorized opening of the tailgate of t...
