  • Patent number: 6478613
    Abstract: Connectors for fuel pumps in motor vehicles have fuel flowing around them. Apart from the connections for the electrical supply lines, such connectors make contact with further electrical components. Corrosive components in fuels attack the connecting points of the connector to the electrical components, so that this can lead to failure of the fuel pump. The new connector is intended to have connecting points which are no longer attacked by the fuel. By extrusion coating parts of the connector with plastic, the connecting points are effectively protected against attack by fuel. Recesses in the plastic extrusion coating allow fuel to still flow around parts of the connector for cooling, while the regions of the connector which are at risk are separated from the fuel.

The connector includes a housing 11 with a rear surface that is held watertight since clearances between a cover 23 and the housing 11 and between the cover 23 and wires 15 are sealed by gelatinous seal members 40. Thus, female terminal fittings 14 are not brought into contact with the gelatinous seal members 40 while being inserted. Therefore, there is no likelihood that the gelatinous seal members 40 are adhered to the female terminal fittings 40 and that the viscosity resistance thereof acts on the female terminal fittings 14.
