Lead-in for electronic bobbins
View Patent ↗A coil bobbin ( 10 ) has a housing ( 12 ) having a floor ( 14 ) with at least one electrical lead-in ( 16 ) projecting therethrough for attachment to a printed circuit board ( 18 ). The at least one electrical lead-in ( 16 ) is provided with thermal-strain relief ( 20 ) between said floor ( 14 ) and the printed circuit board ( 18 ). In a preferred embodiment of the invention the strain relief takes the form of a loop formed in the lead-in.
1. A coil bobbin comprising:
a housing having a floor with at least one electrical lead-in projecting therethrough for attachment to a printed circuit board, said at least one electrical lead-in being provided with thermal-strain relief formed in said electrical lead-in between said floor and said printed circuit board.
2. The coil bobbin of claim 1 wherein said thermal-strain relief comprises at least one loop formed in said electrical lead-in.
3. The coil bobbin of claim 2 wherein said loop comprises a U-shaped portion.
4. The coil bobbin of claim 2 wherein said loop comprises an O-shaped portion.
