CONSTRUCTION SYSTEM FOR A CAPACITIVE SENSOR
First Claim
1. A construction system for a capacitive sensor which extends along a longitudinal axis defining a proximal portion and a distal portion relative to a bar to which it is connected, said capacitive sensor comprising:
- a source electrode arranged in the vicinity of a proximal portion thereof;
an internally hollow screening element which extends along its longitudinal axis, said screening element having a partition intended to configure a first proximal screened chamber and a second distal screened chamber;
an electric field sensor arranged inside said first screened chamber and spaced from the distal end of said source electrode;
a conditioning circuit arranged inside said second screened chamber;
an electric conductor arranged inside said screening element and intended to connect said electric field sensor to said conditioning circuit;
characterized in that it comprises a spacing member provided with a through-duct extending along its axis and a fixing screw;
in that said partition is provided with a hole extending axially along its axis;
in that said spacing member is positioned inside the first chamber with the axis of the through-duct arranged coaxial with the axis of said hole;
in that said spacer is positioned between the proximal face of the partition and the distal face of the field sensor;
in that said field sensor is provided with a threaded hole on its distal face;
in that the head of said screw is arranged inside the second chamber and its shank is arranged so as to pass axially through said hole formed in the partition and across said through duct of said spacing member; and
in that said threaded free end portion of said screw mates with the threaded hole of said field sensor.

Abstract
A construction system for a capacitive sensor comprises a source electrode (210), a screening element (220) with partition (221) which forms a first and a second screened chamber (220.a, 220.b), a field sensor (230), a circuit (250), a spacing member (260) with a through-duct, and a screw (270). The partition (221) is provided with a hole (224) and said spacing member (260) is positioned inside the first chamber (220.a) with the axis (260.y) of the duct arranged coaxial with the axis (224-y) of said hole (224). The same spacing member (260) is positioned between the proximal face (223) of the partition (221) and the distal face (232) of the field sensor (230) and said field sensor (230) is provided with a threaded hole (233). The head (271) of the screw (270) is arranged inside the second chamber (220.b) and its shank (272) is arranged passing axially through said hole (224) and across said through-duct of said spacing member (260) with its end portion which mates with the threaded hole (233) of said field sensor (230).
