发明名称 Inductive ballast coated with an insulation layer and method of coating the ballast
摘要 A method of coating an inductive stabilization ballast for a discharge lamp with an insulating layer and to a stabilization ballast (1) coated by means of this method. The ballast is immersed, together with a synthetic resin cover (10) covering plug-in contact sockets (4 and 5), in a bath (31) of hardenable liquid insulating material. After immersion, a looped suspension member (12)-which was used during the immersion-is broken from the synthetic resin cover so that the electrical plug-in contact sockets become accessible again. This method prevents the plug-in contact sockets from being coated with insulating material.
