Abstract

A printed circuit board arrangement and a method for mounting a product to a main printed circuit board ( 100 ) at a substantially perpendicular angle, the printed circuit board arrangement comprises a main printed circuit board ( 100 ) comprising an elongated slot ( 102 ), and a product ( 128 ) comprising a connector portion ( 130 ) configured to be inserted into the elongated slot ( 102 ). The connector portion ( 130 ) is such that the product ( 128 ) may be attached at a substantially perpendicular angle to the main printed circuit board ( 100 ). The elongated slot ( 102 ) comprises a protrusion ( 104 ), and the connector portion ( 130 ) comprises a spring portion ( 132 ) configured to engage with the protrusion ( 104 ) when the connector portion ( 130 ) is inserted into the elongated slot ( 102 ). This results in a force pressing the connector portion ( 130 ) of the product ( 128 ) to at least one side wall of the elongated slot ( 102 ).

First claim

The invention claimed is:

1. A printed circuit board arrangement, comprising:
a main printed circuit board comprising an elongated slot; and
a product comprising a connector portion configured to be inserted into said elongated slot, such that the product is attached at a substantially perpendicular angle to the main printed circuit board,
wherein the elongated slot comprises a protrusion, and wherein said connector portion comprises a spring portion configured to engage with said protrusion when the connector portion is inserted into said elongated slot, resulting in a force pressing said connector portion of the product to at least one side wall of the elongated slot said force holding the product at a substantially perpendicular angle, and
wherein said spring portion further comprises a recess on a surface thereof, said recess being configured to reduce the force produced by said spring portion.

2. The arrangement according to claim 1 , wherein said protrusion is wedge shaped with at least one sloping surface.

3. The arrangement according to claim 2 , wherein said spring portion is formed with an outer sloping edge, whereby insertion of said connector portion into said elongated slot engages said outer sloping edge with said sloping surface of said wedge shaped protrusion such that said spring portion is forced to bend.

4. The arrangement according to claim 1 , wherein said spring portion is formed by a right-angled cut extending into said product from an outer edge of said product, and said spring portion is formed by the material extending from said right-angled cut towards said outer edge of said product.

5. The arrangement according to claim 1 , wherein said product is a secondary printed circuit board.

6. The arrangement according to claim 5 , wherein said secondary printed circuit board is formed in a FR-4 material.

7. The arrangement according to claim 5 , wherein said secondary printed circuit board is formed in a FR-1 material or a CEM-1 material.

8. The arrangement according to claim 1 , wherein said product is a secondary printed circuit board and said main printed circuit board comprises a main electronic circuit having electrical connections terminating at said elongated slot, and wherein said secondary printed circuit board comprises a secondary electronic circuit having electrical connections terminating in said connector portion.

9. The arrangement according to claim 1 , wherein said product is a metal plate or bracket.

10. The arrangement according to claim 1 , further comprising a soldering joint between the main printed circuit board and said product.

11. A method for mounting a product to a main printed circuit board at a substantially perpendicular angle, said method comprising the steps of:
providing the main printed circuit board comprising an elongated slot which comprises a protrusion, and the product comprising an connector portion comprising a spring portion; and
inserting said connector portion of said product into said elongated slot at a substantially perpendicular angle, wherein inserting said connector portion into said elongated slot comprises:
engaging said protrusion with said spring portion resulting in a force pressing said connector portion of the product to at least one side wall of the elongated slot, and
reducing the force produced by said spring portion through a recess formed on a surface of said spring portion.

12. The method according to claim 11 , wherein the method further comprises the step of:
soldering between the main printed circuit board and said product to provide a soldering joint.

13. The method according to claim 12 , wherein the main printed circuit board comprises a main electronic circuit having electrical connections terminating at said elongated slot, and said product is a secondary printed circuit board comprising a secondary electronic circuit having electrical connections terminating in said connector portion, whereby said soldering joint connects said main electronic circuit and said secondary electronic circuit.
