Claims
- 1. Method for assembling a gyromagnetic device comprising the steps of:
- pre-assembling and positioning an assembly, by means of a dummy which has a same shape and same dimensions as a casing of the gyromagnetic device, said assembly being obtained by stacking in the dummy of:
- (a) a first internal ground plate, which has a plurality of tongues attached thereto,
- (b) a first ferrite and dielectric wafer,
- (c) a conducting core,
- (d) a second ferrite and dielectric wafer, and
- (e) a second internal ground plate, which has a plurality of slits, adapted to receive said plurality of tongues;
- placing the tongues of the first ground plate through the slits of the second ground plate; and
- then deforming said tongues to compress and assemble the unit.
- 2. Method of assembling a gyromagnetic device according to claim 1, wherein the core has a metallic frame, comprising the further step of positioning the core in the pre-assembled unit by means of an internal edge of a cut-out in the metallic frame which comprises said core, said internal edge fitting an external contour of the dummy.
- 3. Method for assembling a gyromagnetic device, comprising a first step of
- preassembling a unit by stacking:
- (a) a first internal ground plate, which has a plurality of tongues,
- (b) a first ferrite and dielectric wafer,
- (c) a conducting core, having microstrips and a frame surrounding external connectors,
- (d) a second ferrite and dielectric wafer, and
- (e) a second internal ground plate, which has a plurality of slits, adapted to receive said plurality of tongues of the first ground plate, to form a pre-assembled unit;
- and comprising the further steps of, in order:
- positioning a pressure and thermal-compensation washer which has a plurality of right angle tongues and a plurality of slanting tongues in a casing;
- positioning a magnet in said right angle tongues;
- placing the tongues of the first ground plate through the slits of the second ground plate, and then folding at least one of said tongues to assemble the unit;
- depositing the pre-assembled unit on the magnet;
- setting the casing and its contents in a housing provided in a first electrode of an electric welding tool;
- laying the first ground plate of the preassembled unit on the casing and its contents and in the housing provided in the same electrode of the electric welding tool;
- electrically welding the first ground plate to the casing under pressure using a second electrode, to join the casing with the first ground plate and thereby complete the gyromagnetic device;
- withdrawing the gyromagnetic device from the initial electrode of the welding tool; and
- cutting the microstrips of the external connectors of the core to remove the metallic core-positioning frame and expose said external connectors.
