Abstract

The support for a printed circuit board, positioned at a distance parallel to the support, includes a base plate and spacers for spacing the printed circuit board from the base plate. The spacers have a head for connecting the spacers to the printed circuit board. The spacers have a bottom portion connected to fastening elements of the base plate provided at a side facing the printed circuit board. The bottom portions are flat and parallel to the base plate. The fastening elements have securing projections for the bottom portions. Each bottom portion has at least two edges engaged by the securing projections. The fastening elements have abutments for the bottom portions, wherein the bottom portions rest at the abutments when engaged by the securing projections.

Claims

1. A support having a printed circuit board positioned at a distance parallel to said support, said support comprising:

a base plate;

spacers for spacing the printed circuit from said base plate;

said spacers having a head for connecting said spacers to the printed circuit board;

said spacers having a bottom portion;

said base plate having a side facing the printed circuit board;

said base plate having fastening elements for securing each one of said bottom portions to said side;

said bottom portions being flat and parallel to said base plate;

said fastening elements having securing projections for said bottom portions;

each one of said bottom portions having at least two edges engaged by said securing projections;

said fastening elements having abutments for said bottom portions, wherein said bottom portions rest at said abutments when engaged by said securing projections.

2. A support according to claim 1, wherein said securing projections and said abutments are stamped from said base plate.

3. A support according to claim 1, wherein said fastening elements have a spring tongue stamped from said base plate and wherein one of said abutments is located at a free end of said spring tongue.

4. A support according to claim 1, wherein said bottom portions are rectangular.

5. A support according to claim 1, wherein said bottom portions are square.

6. A support according to claim 1, wherein:

said spacers have a cylindrical sleeve portion;

said head and said bottom portion are at opposite ends of said sleeve portion; and

said bottom portion surrounds said sleeve portion and laterally projects therefrom.

7. A support according to claim 1, wherein said head is an inwardly rolled end of said sleeve portion.

8. A support according to claim 1, wherein said spacers are stamped from a single piece of sheet metal.

9. A support according to claim 1, wherein said securing projections and said abutments are located within a plane of said base plate.

10. A support according to claim 1, wherein said securing projections and said abutments project from a plane of said base plate.

11. A support according to claim 1, wherein said fastening elements include a depression stamped into said base plate.

12. A support according to claim 11, wherein said depression has a bottom that is positioned at a distance below said side.
