Fuel injection apparatus
First Claim
1. A fuel injection apparatus comprising:
- a body having a high-pressure fuel passage that allows high pressure fuel to flow therethrough;
a nozzle having an injection orifice that allows high pressure fuel to be injected therethrough when the nozzle is opened;
a pressure control unit that controls opening and closing of the nozzle by controlling pressure applied to a nozzle needle of the nozzle in accordance with an electric signal received from an exterior;
a physical quantity measurement unit that outputs an electric signal in accordance with a physical quantity of high pressure fuel;
a first terminal connected to the pressure control unit;
a second terminal connected to the physical quantity measurement unit;
a positioning member that integrally holds the first terminal and the second terminal and locates the first terminal and the second terminal at predetermined spaced apart positions; and
a connector main body portion that receives therein the positioning member, the connector main body portion being made of a resin, wherein;
the positioning member is a separate component from the connector main body portion that is received in the connector main body portion.
