Abstract
Abstract A printed circuit assembly is herein proposed which has a multiplicity of generally L-shaped external terminal elements each of which is connected at one end to a printed circuit on the printed base panel through a soldered joint and which is formed at the other with a plug portion which is to be inserted into a plug socket. The plug portion projects usually perpendicularly from the printed base panel and extends on the same side as the joints on the base panel. The joints on the base panel are therefore soldered in a single dip-soldering operation in which the plug portions of the external terminal elements are kept intact with the result that no changes in size and configuration are invited as a result of the dip-soldering operation. The external terminal elements are thus readily inserted into the plug socket and are prevented from being dislocated or deformed when the plug socket is connected to or disconnected from the group of the terminal elements. The assembly may further include retaining means for securely holding the terminal elements in position relative to the printed base panel.
