Abstract
A fuel injector assembly includes a valve housing, a valve stem that is disposed in the valve housing, a magnetic coil that surrounds the valve housing and is used to displace the valve stem within the valve housing, and a terminal blade. The terminal blade includes a bus bar that provides an electrical connection between the magnetic coil and an external connector. In addition, the terminal blade includes a clip that is connected to the bus bar at a clip first end and to the valve housing at a clip second end. The clip includes a sacrificial portion that is configured to part, for example by dissolving, when the terminal blade undergoes an overmolding process. As a result of the overmolding process, the clip is separated into multiple, spaced portions.

A terminal blade fora fuel injector that includes include a valve housing that supports an injector valve, and a magnetic coil that surrounds the valve housing and is configured to actuate the valve, the terminal blade configured to provide an electrical connection between the magnetic coil and an electrical connector, the terminal blade comprising:
- an electrically conductive bus bar that is configured to form an electrical connection with the electrical connector and the magnetic coil;
- and
- a clip that is connected to the bus bar at a clip first end and to the valve housing at a clip second end, the clip including a sacrificial portion, the sacrificial portion configured to part when the terminal blade undergoes an overmolding process in such a way that the clip is separated into multiple portions.
A fuel injector assembly comprising:
- a valve housing;
- a valve stem that is disposed in the valve housing and moveable relative to an inner surface of the valve housing along a valve housing longitudinal axis,
- a magnetic coil that surrounds the valve housing and is used to actuate the valve stem;
- and
- a terminal blade that is configured to provide an electrical connection between the magnetic coil and an external connector, the terminal blade comprising:
- an electrically conductive bus bar that is configured to form an electrical connect the external connector and the magnetic coil;
- and
- a clip that is connected to the bus bar at a clip first end and to the valve housing at a clip second end, the clip including a sacrificial portion, the sacrificial portion configured to part when the terminal blade undergoes an overmolding process in such a way that the clip is separated into multiple portions.
