Patent number: 5949319Abstract: A bar coil for use as an ignition coil in internal combustion engines (of motor vehicles) is designed so that casting resin can be introduced into an interior space of the bar coil in a manner that is advantageous from a manufacturing standpoint. The bar coil has a centrally arranged channel that extends from a connecting segment, through a core of the bar coil, and to a pan-shaped bottom area of the interior space of the bar coil. Casting resin flowing through the channel enters the closed bottom area, from which it is diverted as a uniform front to flow through gaps in the bar coil to the connecting segment.Type: GrantFiled: May 7, 1998Date of Patent: September 7, 1999Assignee: Robert Bosch GmbHInventors: Karl-Heinz Nuebel, Wolfgang Endres
