Electrical power distribution unit and electrical punched grid therefor
View Patent ↗An electrical power distribution unit ( 1 ) for an electrical system has a printed circuit board ( 200 ) with a punched grid ( 100 ) arranged thereon. An electrical component ( 300, 310 ) is arranged on the printed circuit board on a side of the punched grid ( 100 ). An electrical contact ( 350 ) of the electrical component projects through a passage opening in the printed circuit board. The punched grid is arranged between the electrical component and the printed circuit board, and an opening is formed in the punched grid in an area ( 130 ) around the electrical contact. The punched grid has a current infeed ( 110 ) which comprises a plurality of tongues ( 111, 112; 113 ). At least one of the tongues is bendable out of a plane of the punched grid in such a way that two of the tongues form a mutually adjacent common portion ( 115 ), which is electrically contactable by an electrical plug connector.
1. An electrical power distribution unit for an electrical system, comprising:
a printed circuit board, a punched grid arranged on the printed circuit board, and an electrical component, which is arranged on the printed circuit board on a side of the punched grid,
an electrical contact of the electrical component projecting through a passage opening in the printed circuit board,
wherein the punched grid is arranged between the electrical component and the printed circuit board, and an opening is formed in the punched grid in an area around the electrical contact of the electrical component;
wherein a current infeed of the punched grid comprises at least two tongues projecting out of a plane of the punched grid, which rest against one another in electrical contact at a common portion.
2. The electrical power distribution unit according to claim 1 , wherein punched grid pins are provided in the immediate vicinity, separated by a gap which is narrow in comparison with the dimensions of the punched grid, of the portions in the punched grid which are provided between the printed circuit board and the electrical component.
3. The electrical power distribution unit according to claim 1 , wherein the punched grid pins for supplying current to the printed circuit board are provided between the printed circuit board and the electrical component or directly adjacent an outer boundary of the electrical component.
4. The electrical power distribution unit according to claim 1 , wherein the portion of the punched grid located between the electrical component and the printed circuit board extends through and under the electrical component.
5. The electrical power distribution unit according to claim 1 , wherein the portion of the punched grid located between the electrical component and the printed circuit board extends through and under the electrical component between two substantially parallel sides of the electrical component.
6. The electrical power distribution unit according to claim 1 , wherein the area of the punched grid removed for the electrical contact is located wholly between the electrical component and the printed circuit board.
7. The electrical power distribution unit according to claim 1 , wherein the electrical component is seated on the portion of the punched grid located between it and the printed circuit board.
8. The electrical power distribution unit according to claim 1 , wherein a tongue is substantially rectangular, L- or U shaped in plan view, and when bent out, the tongue projects at approximately a 90° angle from the punched grid.
9. The electrical power distribution unit according to claim 8 , wherein a portion of at least one tongue of the current infeed may additionally be bent at least one further time in such a way that this tongue forms a common, mutually adjacent portion with another tongue.
10. The electrical power distribution unit according to claim 9 , wherein the portion bendable a second time may be bent at approximately a 180° angle, in order to form a common portion with a tongue.
11. The electrical power distribution unit according to claim 1 , wherein the current infeed comprises just two tongues bendable against one another, which are substantially U-shaped in plan view and, when bent against one another, the common portion of the two tongues is formed substantially of one branch of the U-shaped tongues.
12. The electrical power distribution unit according to claim 1 , wherein the mutually adjacent portions of the tongues together produce a thickness which corresponds to an internal dimension of a tab of the electrical current infeed of the punched grid.
13. The electrical power distribution unit according to claim 1 , wherein fold joints of the tongues are located centrally relative to an opening formed by the branches of the tongues lying directly opposite one another.
14. The electrical power distribution unit according to claim 1 , wherein the punched grid comprises openings, the respective dimensions of which are such that only electrical contacts of an electrical component may be inserted through the openings.
15. The electrical power distribution unit according to claim 1 , wherein the punched grid has a thickness of less than 0.8 mm.
