Noise suppressor unit
View Patent ↗The invention relates to a noise suppressor unit ( 1 ) for installing and mounting a common mode choke for a noise suppressor onto a circuit board ( 3 ). The noise suppressor unit ( 1 ) comprises a circuit board holder ( 7 ), onto which the toroid ( 4 ) is positioned, the toroid being coiled with at least two coils ( 5 ), the circuit board holder ( 7 ) comprising connecting plates ( 8 ), wherein one coil end ( 6 ) at the most is or more coil ends ( 6 ) are connected to each connecting plate ( 8 ) and wherein the connecting plates ( 8 ) are intended to be surface mounted to mounting surface areas in the circuit board ( 3 ), and wherein the connecting plates ( 8 ) are electrically insulated from each other, and lifting means ( 9 ) for an assembly head or the like of an automatic assembly machine for placing the noise suppressor unit ( 1 ) onto the circuit board ( 3 ) by the automatic assembly machine.
1. A noise suppressor unit comprising:
a circuit board base,
a toroid coiled with at least two coils, each coil comprising two coil ends,
connecting plates that are electrically insulated from each other, wherein,
the toroid is positioned on the circuit board base, each of the coil ends is connected to one of the connecting plates, the connecting plates being positioned to form electrical connections with a circuit board.
2. A noise suppressor unit as claimed in claim 1 , wherein the connecting plates are so dimensioned and designed that the toroid is apart from the connecting plates.
3. A noise suppressor unit as claimed in claim 1 , wherein each connecting plate comprises an upper connecting plate, to which one coil end at the most is connected, and a lower connecting plate, which is in an electrical connection with the upper connecting plate and which is intended to be surface mounted to mounting surface areas in the circuit board.
4. A noise suppressor unit as claimed in claim 3 , wherein the upper connecting plates are so dimensioned and designed that the toroid is apart from the upper connecting plates.
5. A noise suppressor unit as claimed in claim 3 , wherein the lower connecting plates are substantially rectangular.
6. A noise suppressor unit as claimed in claim 1 , wherein the noise suppressor unit comprises four connecting plates and the toroid is coiled with two coils.
7. A noise suppressor unit as claimed in claim 6 , wherein the circuit board base is substantially rectangular and each connecting plate is located at one corner of the circuit board base.
8. A noise suppressor unit as claimed in claim 1 , wherein the connecting plates are made of copper or copper metal.
9. A noise suppressor unit according to claim 1 wherein the suppressor unit has a place for lifting means to grab the noise suppressor unit.
10. A noise suppressor unit as claimed in claim 9 , wherein the place for lifting means is located in the middle opening of the toroid.
11. A noise suppressor unit as claimed in claim 9 , wherein the place for lifting means is located on the surface of a circuit board holder.
12. The noise suppressor unit of claim 1 , wherein the toroid coiled with at least two coils forms a common on mode choke.
13. A noise suppressor unit comprising:
a circuit board base configured to be positioned on a circuit board,
a toroid positioned on the circuit board base,
a place for lifting means to grab the noise suppressor unit, the place being located at the middle opening of the toroid, on the surface of the circuit board base.
14. A noise suppressor unit comprising:
a toroid; and
an intermediary connecting base on which said toroid is positioned, said intermediary connecting base being configured to connect said toroid to a circuit board,
wherein said intermediary connecting base includes a surface portion located at the middle of said toroid, said surface portion and said toroid being dimensioned so as to allow a lifting unit to grab said noise suppressor unit.
