Abstract
A device for capturing an electric current for a rail vehicle includes a pad intended to come into contact with an electric power rail, a frame and an electrically conductive arm which mechanically and electrically connects the frame to the pad. The capture device includes a device for measuring the mechanical forces exerted on the arm. The device includes strain sensors which are in contact with the arm and integrated on the inside of an electrical isolation structure, such that the strain sensors may be electrically isolated from the arm. The isolation structure includes a glue layer and a ceramic layer covering the glue layer. The strain sensors are arranged on the ceramic layer.

A device for capturing an electric current for a rail vehicle, the capture device including:
- a pad intended to come into contact with an electric power rail;
- a frame;
- an electrically conductive arm which mechanically and electrically connects said frame to said pad, the arm comprising a central part coupling said frame to a support portion on which said pad is mounted;
- and
- a measuring apparatus for measuring the mechanical forces exerted on said arm, the measuring apparatus comprising strain sensors which are integrated on the inside of an electrical isolation structure, such that the strain sensors may be electrically insulated from said arm, the isolation structure comprising a glue layer deposited on a receiving surface and a ceramic layer covering the glue layer, and wherein said strain sensors are arranged on the ceramic layer.
