A backshell for connecting an overall-shielded harness including shielded cables to a connector, the backshell including a sleeve having a full toothed ring, a first external area for receiving the terminations of the shielding, and a second external area for receiving the overall-shielding of the harness, the backshell further including an attachment ring having a first internal area and arranged so that it can slide over the sleeve up to an abutment position in which it covers the first external area of the sleeve so as to cover the terminations of the shielding. This backshell is designed to make a terminated shielding harness and a connection protected against EM interference between the terminated shielding harness and a connector.

Backshell with electromagnetic protection

An optical probe that measures the level of a liquid in a tank includes a transparent and refracting optical waveguide for receiving an injection of a collimated light beam. The optical waveguide internally reflects the collimated light beam according to a total reflection regime in any part of the optical waveguide located in a gaseous medium and refracts the collimated light beam according to a refraction regime in any part of the optical waveguide immersed in a liquid medium. The optical waveguide switches from the total reflection regime to the refraction regime at the interface between the gaseous medium and the liquid medium, and mirrors are arranged around said optical waveguide and reverse the path of a light beam collimated and refracted by the optical waveguide, the optical path covered by the collimated light beam representing the level of the liquid in the tank.
