Electrical connector for a SCR doser

An electro-actuator comprising:

• an overmoulded coil from an outer face of which protrudes a block wherefrom extends a plurality of electrical pins in electrical contact with a plurality of terminals of an electrical connector, said electrical connector comprising;
• a connector body and a plurality of electrical terminals for electrically connecting the pins of said electro-actuator, the connector body defining a passage for an electrical cable and a recess which arranges the plurality of electrical terminals;
• the connector body further comprising a base and two opposing resilient arms extending from said base, said resilient arms defining a space therebetween;
• and
• a hook mechanically engaged with said block;
• wherein said space comprises said recess and a downward portion for receiving the block, said downward portion being adjacent and continuous with said recess and being wider than said recess;
• wherein each resilient arm defines at its end a spur oriented toward the opposite arm and having a sloped outer face configured such that a distance between the opposing outer faces is smaller than a width of the block, the spurs defining said hook;
• wherein during engagement of the electrical connector to the electro-actuator, said resilient arms deflect from a rest position and when the electrical connector is fully engaged, said resilient arms self-return to said rest position.

A doser adapted for spraying a fluid, said doser having a body enclosing an electro-actuator including pins protruding from a connector block, the body being provided with an aperture enabling insertion of an electrical connector, the electrical connector comprising:

• a connector body and a plurality of electrical terminals for electrically connecting the pins of said electro-actuator, the connector body defining a passage for an electrical cable and a recess which arranges the plurality of electrical terminals;
• the connector body further comprising a base and two opposing resilient arms extending from said base, said resilient arms defining a space therebetween;
• and
• a hook configured to mechanically engage with the connector block;
• wherein said space comprises said recess and a downward portion for receiving the connector block, said downward portion being adjacent and continuous with said recess and being wider than said recess;
• wherein each resilient arm defines at its end a spur oriented toward the opposite arm and having a sloped outer face configured such that a distance between the opposing outer faces is smaller than a width of the connector block, the spurs defining said hook;
• wherein during engagement of the electrical connector to the electro-actuator, said resilient arms deflect from a rest position and when the electrical connector is fully engaged, said resilient arms self-return to said rest position.
