Polygonal part having cavities for a panel core, in particular of a satellite antenna reflector
The polygonal part ( 1 ) has, on each side (C 1 to C 6 ), at least one of the following assembly elements: at least one lug ( 3 ), at least one recess ( 4 ), each of said lugs ( 3 ) and each of said recesses ( 4 ) of the part ( 1 ) having a trapezoidal shape, with in each case complementary shapes, the trapezium of each of said lugs ( 3 ) widening towards the outside of the part ( 1 ) and the trapezium of each of said recesses ( 4 ) widening towards the inside of the part ( 1 ), and each of said lugs ( 3 ) having a width, defined transversely with respect to a right bisector of the corresponding trapezium, which is greater than the width of each of said recesses ( 4 ).
1. A part intended for a panel core, in particular for a satellite antenna reflector, said part being substantially planar and having a polygonal shape with cavities, each side of the part featuring at least one of the following assembly elements: at least one lug, at least one recess, characterised in that each of said at least one lug and each of said at least one recess of the part have a trapezoidal shape, with in each case complementary shapes, the trapezoidal shape of each of said at least one lug widening towards an outside of the part and the trapezoidal shape of each of said at least one recess widening towards an inside of the part, and in that each of said at least one lug has a maximum width defined transversely to a perpendicular bisector of the trapezoidal shape, which is greater than a maximum width of each of said at least one recess.
2. The part according to claim 1 , wherein each of said at least one lug is identical, and wherein each of said at least one recess of the part is identical.
3. The part according to claim 1 , characterised in that each of said at least one lug and each of said at least one recess of the part has the shape of an isosceles trapezium.
4. The part according to claim 1 , characterised in that the width of each of said at least one lug is included in a defined range of widths between 100% and 150% of the width of each of said at least one recess.
5. The part according to claim 1 , characterised in that each of said at least one lug has a length defined along a perpendicular bisector of the corresponding trapezoidal shape, which is less than or equal to a length of each of said at least one recess.
6. The part according to claim 1 , characterised in that each side of the part features at least two assembly elements.
7. The part according to claim 6 , characterised in that each side of the part features the same assembly elements.
8. The part according to claim 1 , characterised in that said part has a generally hexagonal shape.
9. A part intended for a panel core, in particular for a satellite antenna reflector, said part being substantially planar and having a polygonal shape with cavities, each side of the part featuring at least one of the following assembly elements: at least one lug, at least one recess, characterised in that each of said at least one lug and each of said at least one recess of the part have a trapezoidal shape, with in each case complementary shapes, the trapezoidal shape of each of said at least one lug widening towards an outside of the part and the trapezoidal shape of each of said at least one recess widening towards an inside of the part, and in that each of said at least one lug has a maximum width defined transversely to a perpendicular bisector of the trapezoidal shape, which is greater than a maximum width of each of said at least one recess, characterised in that said at least one lug has a length defined along a perpendicular bisector of the trapezoidal shape which is less than a length of said at least one recess.
