ELECTRICAL CONNECTOR AND TERMINAL FOR A WINDING OF CAPILLARY WIRE OF AN IGNITION COIL FOR INTERNAL COMBUSTION ENGINES, IGNITION COIL FOR INTERNAL COMBUSTION ENGINES AND FITTING PROCESS FOR THE ENGAGEMENT OF SAID CONNECTOR

摘要

A connector (1) for the connection to a magnetic coil (B) wound onto a support element (10) is described. The magnetic cable (C) that realizes the coil (B) is covered by an insulating layer. The connector comprises an elastic spring contact element (1,100,200,50) which is made of conductive material and which in the rest condition tends to return into the closed condition. The spring contact element (1,100,200,50) is kept in an open condition during insertion of the connector on the support element (10). Furthermore, the spring contact element (1,100,200,50) includes on its inner walls cutting elements (1d, 100d, 200d, 52e) for cutting into the insulating layer. Finally, stop means are provided in order to prevent the spring contact element closing by more than a given amount. At the end of the closing phase the spring contact element (1,100,200,50) performs a mechanical retention function and at the same time creates an electrical contact between the support element (10) and the magnetic coil (B).
