Plastics housing for electric circuit board

摘要

The housing has a peripheral mounting flange with at least one opening in which a metal insert (3) can be fitted, the housing secured to a metal carrier via a fixing screw fitted through the metal insert. The housing has an electrical coupling device (4) for electrically connecting a circuit board terminal (5) to the metal insert and hence to the metal carrier. The coupling device may be provided by a separate component or by a metal layer applied to the inside of the plastics housing.
